Al ritmo actual de extinción, la mayoría de las especies desaparecerán antes de que podamos describirlas. El consorcio del Atlas Europeo de Genomas de Referencia puso en macha en 2022 un proyecto para comprender la biodiversidad, monitorear sus cambios y determinar cómo frenar su disminución mediante el uso de la ciencia genómica. Dos años después, ha sentado las bases metodológicas y colaborativas para llevarlo a cabo y ha publicado los genomas de referencia de alta calidad de 98 especies europeas. Hemos entrevistado a Ana Riesgo, investigadora en el Museo Nacional de Ciencias Naturales (CSIC) y una de las coordinadoras del proyecto en España. Alba Calejero nos ha informado de la presentación de un nuevo catálogo de distancias cósmicas para desvelar los misterios de la formación del universo, con testimonios de David Navarro y Pablo Renard, del Instituto de Ciencias del Espacio (CSIC). En 1783 los hermanos Elhuyar descubrieron el wolframio. Aunque su símbolo es la W, la IUPAC lo denomina tungsteno, algo con lo que no están de acuerdo muchos científicos españoles que, como nos ha contado José Manuel Torralba, reclaman que se adopte su denominación original. En el Año Cajal, José Luis Trejo nos ha hablado de un corto producido por el CSIC y la FECYT sobre los “Cuentos de vacaciones” escritos por nuestro premio Nobel, relatos con finalidad pedagógica sobre el progreso científico en los que siempre están presentes el microscopio y la microbiología. Con Javier Ablanque y su máquina del tiempo hemos viajado al Londres de 1930 para conocer a los golpeadores de ventanas, encargados de despertar a los vecinos disparando guisantes o garbanzos a los cristales, y conocer la física de la cerbatana. En nuestros "Destinos con ciencia", nuestra compañera Esther García nos lleva de viaje al Reino Unido para conocer los lugares donde se gestó el descubrimiento de la doble hélice de ADN. Escuchar audio

Stemningen er intens til IUPAC's generalforsamling i Genève, Schweiz i 1997. Stormagterne; USA, Rusland og Tyskland er i gang med noget, der bedst kan sammenlignes med en krig. En krig, der heldigvis ikke bliver udkæmpet med våben. Det er i stedet en krig, der kæmpes med argumenter og videnskabelige standpunkter, og som senere får navnet “Transfermium Wars”. Og et af de grundstoffer, der er omdrejningspunktet for denne krig, er grundstof 105.Periodisk – en RAKKERPAK original produceret af Rakkerpak Productions.Historierne du hører bygger på journalistisk research og fakta.

What products do you use with cobalt in them? Can cobalt ever precipitate out of solution and cause problems? Under what conditions can this happen? Can cobalt in a product become a foulant or degradation catalyst for an RO membrane if used?    Periodic Water Table With James McDonald # 52 With everything happening during Industrial Water Week on the podcast, we didn't have room for that week's edition, but don't worry, because the 52nd and last Periodic Water Table with James topic is none other than…  Water or H2O or dihydrogen monoxide or even oxidane, the IUPAC-compliant name for water. There are many names for water. It has inspired art, poetry, music, architecture, comics, inventions, love, and more. It has helped both create and destroy civilizations. It is at the very heart of what you and I do every day as we practice the noble profession of industrial water treatment. It is water. How much do you know about water though? Why is water a liquid at room temperature when other molecules of similar or even heavier molecular weights are gasses? How does its density change with temperature? How conductive is pure water? Is water a stable molecule or does it ever disassociate? Have you taken out a steam table lately and looked at the trends as pressures and temperatures change?

A química Márcia Foster Mesko, professora da Universidade Federal de Pelotas (UFPEL), no Rio Grande do Sul, foi premiada pela União Internacional de Química Pura e Aplicada neste domingo (20) em Haia, na Holanda, durante o congresso mundial de Química. Ela foi a única pesquisadora da América Latina selecionada neste ano para receber a distinção de “Mulheres Notáveis na Química ou Engenharia Química”. Ela é a terceira brasileira a receber este prêmio, depois da professora Vanderlan Bolzani (Unesp) em 2011, e da professora Yvonne Mascarenhas (UFSCar) em 2017. Neste episódio, falando diretamente de Haia, a Profa. Márcia comenta sobre o prêmio, seu trabalho com a determinação de halogênios em baixa concentração, e seu trabalho de extensão com meninas do ensino fundamental.

We discuss the origins of names in organic chemistry, starting the with chaos when Lavoisier and friends didn't create such a terminology in the 1780s. August Hofmann, in the 1860s, began to systematize things for his students, but it didn't take hold. Charles Friedel, though, got an International Congress of Chemistry in 1889 to consider the problem, which created an 1892 Geneva Nomenclature Congress. Finally some sense began to creep into organic nomenclature, and this eventually led to IUPAC after World War I. Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

Welcome to “Analytically Speaking,” the podcast from LCGC and Spectroscopy. Here in Episode 13, podcast host Dr. Jerry Workman talks to Dr. Paul C. DeRose, who is a senior research chemist at the National Institute of Standards and Technology (NIST) and leads the NIST Biochemical Science Division's project in luminescence standards development for chemical analysis and assay validation. We spoke to Paul about his current research interests in fluorescence and luminescence spectroscopy, specifically concerning the development of fluorescence standards and methods for validation of chemical and clinical assays. Paul's research has resulted in publications in various areas of fluorescence spectroscopy and microscopy. He has developed fluorescence standard guidelines and recommendations for ASTM, IUPAC, and the US Pharmacopeia. He is also the chair of ASTM E13.01.01 sub-committee on Molecular Luminescence.

We examine the founding of the International Union for Pure and Applied Chemistry, the organization that sets standards for names of elements and compounds, starting with the first international chemical congress at Karlsruhe, Germany, the 1892 Geneva Rules, a 1911 International Association of Chemical Societies, and finally the IUPAC founded in 1919. We look at some of the controversies over committees trying formulate rules for naming compounds, and what and where exactly the IUPAC is.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

We discuss the discovery of elements 93 to 103, from 1940 through the early 1960s. We hear of Enrico Fermi's work, Otto Hahn and Lise Meitner's discovery of fission, McMillan and Abelson's success, and then the long tenure of Glenn Seaborg discovering elements. Albert Ghiorso was added to the mix. There were Cold War controversies over discoveries at Berkeley versus Dubna and even the Nobel Institute in Sweden. IUPAC was inconsistent with its imprimatur on discovery. Finally, we hear something of the tribulations and difficulties in doing radioactive analytical chemistry on tiny amounts of elements.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

Como muchos de nuestros oyentes recordarán del instituto, el peso atómico es el número que se encuentra debajo del símbolo de un elemento químico en la Tabla Periódica. En algunos casos no es un número fijo (p. ej. el boro procedente de Turquía tiene un peso atómico menor que el boro de California debido a las diferencias en su composición isotópica). Estos pequeños cambios podrían parecer insignificantes, pero son importantes para determinar la pureza y el origen de un elemento o de un alimento natural, investigar casos de dopaje, seguir el rastro de contaminantes en el aire o en el agua o identificar la procedencia de restos arqueológicos. La Unión Internacional de Química Pura y Aplicada (IUPAC) acaba de revisar el peso atómico de cinco elementos (Ar, Ir, Hf, Pb e Yb) en una colaboración internacional de muchos meses de trabajo que ha requerido el empleo de los últimos avances tecnológicos. Hemos entrevistado a Javier García Martínez, presidente de la IUPAC desde el pasado mes de enero. La semana pasada hablamos de la primera fotografía de Sagitario A*, el agujero negro situado en el centro de nuestra galaxia. Hoy Montse Villar nos ha contado las investigaciones que se han hecho en los últimos ha contado 50 años para que esa imagen sea posible. Jesús Martínez Frías nos ha informado del sorprendente hallazgo de microorganismos de 800 millones de años de antigüedad conservados en cristales de sal hallados en la Formación Browne (Australia central). En nuestra historia de la ciencia, Nuria Martínez Medina ha dedicado un capitulo a la francesa Jeanne Baret, la primera mujer que dio la vuelta al mundo en la expedición de Bouganville aunque para eso tuvo que disfrazarse de hombre. Fernando Blasco nos ha hablado del juego matemático “Torre de Hanoi”. Son discos de radio creciente apilados en una de las tres varillas de un tablero. El objetivo es mover la pila en otra de las varillas en el menor número posible de pasos, siguiendo una serie de reglas: Sólo se puede mover un disco a la vez; no puede haber nunca un disco de mayor tamaño o sobre uno de tamaño menor; y solo se puede desplazar el disco que se encuentre arriba en cada varilla.

Monica Is a group leader at ICIQ (Institut Català d'Investigació Química / Institute of Chemical Research of Catalonia), Tarragona, Spain. Her group focuses on the ‘Development of new chemical transformations: From organometallic mechanistic studies to catalysis'. Prior to her current position, Monica conducted postdoctoral research at the University of Michigan, Ann Arbor, USA, which followed awarding of her Ph.D. from the University of Valladolid, Spain – where she also earnt her B.Sc. and M.Sc.In 2018, Monica was selected as one of the ‘Talented 12' by Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society (ACS). She is also involved in outreach activities to increase the visibility of women in Science. You will hear the following terms used during the interview. I've included some descriptions here. NMR – Nuclear Magnetic Resonance subjects samples to a strong magnetic fields and measures the resonance pattern of the nuclei. It is widely used to study the structure and dynamics of organic molecules.Palladium – A chemical element with atomic number 46. It is a rare metal and over 50% of palladium supply is used in catalytic processes, most commonly catalytic converters attached to automobile exhausts.Cobalt A chemical element with atomic number 27. Most commonly produced as a by-product of Copper and Nickel production, the main use for colbalt is in Li-ion batteries, and the production of certain high-strength metal alloys.Transition metal – in chemistry, the term transition metal is defined in one of three ways:Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. In practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".The expanded IUPAC definition specifies which elements are included. As well as the elements of groups 4 to 11, scandium and yttrium are included Lanthanum and actinium, which are considered group 3 elements, are however classified as lanthanides and actinides respectivelyNucleophile – A chemical species that forms bonds with electrophiles by donating an electron pair.Oxidant – A substance that has the ability to oxidize another substance. In chemical reactions this refers to the oxidant accepting electrons.Intermediate – A chemical entity that is formed during a reaction, but that is typically converted to another form when the reaction completes. During the discussion, Monica mentions a number of the publications that her groups have produced. Links to her publications are available from the group website. Monica is contactable on social media, and you can find her on LinkedIn https://www.linkedin.com/in/monica-h-perez-temprano-3659ab3b/ The group website is https://www.iciq.org/research/research_group/dr-monica-h-perez-temprano/ On Twitter, the group is @Perez_Temprano Our theme music is "Wholesome" by Kevin MacLeod (https://incompetech.com)Music from https://filmmusic.ioLicense: CC BY (http://creativecommons.org/licenses/by/4.0/) Connect with me (Paul) at https://www.linkedin.com/in/paulorange/H.E.L. group can be found at www.helgroup.com online,on LinkedIn at https://www.linkedin.com/company/hel-group/ on Twitter, we're @hel_group, https://twitter.com/hel_groupor search for us on Facebook 

During our recent Happy Hour, we had an interesting discussion on a spate of recent incidents that brought us around to talking about a skunky compound This topic was given to us by a Specialist listener on our Monthly Happy Hour. Seems there is a stinky fruit that has been giving the local college some issues, so it gave us the opportunity to talk about the cause.

Thanks for listening and watching! Don't just get on the job, get into the job! Was talking about a few incidents he heard about where people were eating a fruit that smelled so bad that people called the FD to investigate. The fruit is called Durian Fruit [Show pic of Durian fruit] The Durian Fruit is ugly. It's like a sea urchin. Its big, thorny, and super stinky! It depends on what side of the fence you sit, there are the people that think it smells a pleasant smell. Some say it smells like gym socks. [kind of like how europeans find our chocolate] It has been found that the overall odor of durian pulp could be mimicked by only two compounds: fruity smelling ethyl (2S)-2-methylbutanoate and roasted onion-like smelling 1-(ethylsulfanyl)ethane-1-thiol. Did you say Thiol?! Why yes I did… Then lets talk about some thiols and what they are It's a sulfur compound. Technically it's an organosulfur compound. Basically is a sulfur-hydrogen group thats attached to an organic molecule OR an alkyl group. Now this group can be called a few things, all meaning the same. You could say thiol group, sulfhydryl group or a sulfanyl group. All mean the same. All stinky. Oddly enough thiols are an analogue of alcohols. The word thiol means a mix of the works alcohol and sulfur in Greek.  You may be asking yourself, where would I find some of these little bombs? You can find it in Hydrogen Sulfide or mercaptans. Now taking a look purely at the periodic table, you would find the Sulfur element immediately south of the Oxygen element. Meaning I would assume it has many of the same properties as oxygen (and I think we're pretty comfortable with oxygen as an element) But the SH functional group is MUCH different than an OH function. The purely SH group is what they would call a sulfhydryl group in the IUPAC naming system.  On a side note, the word mercaptan is an ancient word. Its from the latin language. So the older ones were named by saying an alkyl group, then “mercaptan”. Old skool. You may also find them in the brewing process as a bug in the software. When you add hops to the wort there is one specific one  One of the unique properties of Thiols is that they don't form hydrogen bonds, so they have a low boiling point. What does that mean to you as a responder? [the low BP means high VP therefore its coming to find my nose] Right, The 2-buten-1- thiol above is one of the components of skunk spray. Mercaptan (aka Methanethiol) is purposely added to bottled gas and natural gas in order to reveal leaks.  More places are asparagus, cabbage, red grapes, apples and peaches. Are they acidic or basic? They tend to be more basic. Are they flammable? They can be. The mercaptans are, but not everyone is.

Speciation is defined as: ‘the distribution of an element amongst defined chemical species in a system’ (IUPAC). Chemical species include isotopic composition, electronic or oxidation states and molecular structures. Speciation analysis is the analytical process of identifying and/or measuring the amounts of one or more individual chemical species in a sample.Chemical and elemental species are important in many fields of science and health. Human health and nutrition can be influenced by the presence or absence of certain chemical species such as iron, selenium, arsenic, and mercury. Some chemical species are potentially toxic and are targets of concern. In this presentation, learn about the importance and role of chemical species.Hosted by Patricia Atkins from SPEX CertiPrep.Stay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexcertiprep/Stay connected with SPEX SamplePrep!Website: https://www.spexsampleprep.com/Facebook: https://www.facebook.com/SPEXSamplePrep/Twitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexsampleprep/Support the show (http://www.spexcertiprep.com)

* How Did Radioactive Decay Start in Earth's Crust? (Re-run during recovery from a minor accident while Bob was out boating. "See you guys, Lord-willing, next week!") Real Science Radio co-hosts Bob Enyart and Fred Williams describe Walt Brown's Hydroplate Theory from his book, In the Beginning, and Dr. Brown's discovery of the origin of Earth's radioactivity. Ways to learn about the origin of Earth's radioactivity: - Listen to today's program (above) - Read this written show page - Read Bob's brief 2019 RMCF articles Part 1 & Part 2 - Read Walt's theory right here at hpt.rsr.org - See this visually just below in Bryan Nickel's video tutorial - Read Walt's theory beginning on page 380 of the PDF of ITB 9th Edition. Consider: - God created a paradise for mankind so no radioactivity would have existed on the original Earth because radioactive decay can cause birth defects, disease, and death with lowered lifespans. - For ex., uranium formed on Earth, as evidence by its worldwide ratio (see below)  - The fourth state of matter, beyond solid, liquid, and gas, is plasma (lightning, neon lights, etc.) which is like a gas but with the electrons stripped away.- By the piezoelectric effect, pressure on quartz produces an electric voltage and the granite in the Earth's crust is more than one-fourth quartz. - Z-pinched electrical pulses produce nuclear combustion by stripping away electrons and then squeezing together nuclei producing radioactive and other elements. - Decay rates speed up by a billion times or more when half lives are measured for atoms stripped of their electrons; for example when ionized the 41-billion year half life of rhenium's beta decay speeds up to 33 years.- Atmospheric lightning produces new isotopes (most of which decay within minutes).  2017 Update: Nature reports that lightning storms "trigger atmospheric photonuclear reactions" that produce isotopes. [In 2010 Dr. Brown published his Radioactivity theory including references to little noticed research showing that atmospheric lightning produces radioisotopes (and also explains the Oklo Natural "Reactor").] 2017 Science Headlines: Lightning produces radioisotopes. (See ITB since 2010.)  - Earthquake Lights: Earthquakes produce piezoelectric lightning flashes in the ground and also, coming out of the ground. (See also rsr.org/eql.) 2017 Update: Twitter video of this phenomenon during Mexico's deadly magnitude 8.1 quake. [Thanks to RSR London listener Remy for the heads up.] 2016 Update: Video of earthquake lights surface, this time after New Zealand's magnitude 7.8 quake epicentered between Christchurch and Wellington. 2014 Update: A paper in the journal Seismological Research Letters is reported on in USA Today's Scientists find records of rare 'earthquake lights'. 2013 Update: This may be the phenomena causing the apparent pre-quake disturbances in the ionosphere that led scientists to consider a possible earthquake warning system, as reported in 2008 by BBC News, and pursued by the U.K. and Russia in 2011 and generating continued interest and research in 2013 in a European Geophysical Union conference presentation, and here with RSR's 2014 interview with QuakeFinder. - The journal Nature reports that an average earthquake produces hundreds of millions of volts. - During the upheaval of the global flood pressure in the crust produced enormous voltages that produced plasma surges in the crust. - Those voltages smashed together the nuclei of atoms to create, in the crust, radioactive elements and massive, instantaneous apparent radioactive decay.- Missing uniform distribution of earth's radioactivity: From our RSR debate with theoretical physicist (emphasis on the theoretical), Lawrence Krauss... The theory of chemical evolution claims that all of our radioactive elements were created in the explosion of stars, but that would predict a relatively uniform distribution on Earth, at least throughout the crust, and possibly the mantle too. However, in an otherwise contentious interview, Krauss agreed with Enyart's statement on air that 90% of Earth's radioactivity (uranium, thorium, potassium-40, etc.) is located in the continental crust, and Krauss added, a mystery for him, that it tends to concentrate around granite! That is, that 90% is not in the mantle nor in the enormous amount of the crust which lies under the oceans, but our planet's radioactivity is concentrated in 1/3rd of 1% of the Earth's mass, in the continental crust. (Further, the release of it's heat has not yet reached a steady state.) Krauss offered a partial explanation: that uranium was originally evenly distributed throughout (an alleged) molten earth but being a large atom, it floated toward the surface. This the bias of this physicist led him to forget, apparently, that it is density, and not size, that causes things to float. Even denser than gold, uranium is one of the most dense elements (excluding atheists and other manmade phenomena). Further, for argument's sake, that would only explain the relative absence of radioactivity deep in the Earth, but would not explain uranium's distancing itself from the mantle and from the oceanic crust, nor its affinity for the continents and even, of all things, for granite. Further, under Krauss' belief in the widespread falsehood that the planet was once molten, if so, then the gold in the crust should have sunk to the core! The creationists, on the other hand, have a theory based on observational science as to why radioactivity is concentrated around granite. - Absurd consistency of uranium isotopes IF formed in space: Consider this from Walt Brown's Origin of Earth's Radioactivity chapter: The isotopes of each chemical element have almost constant ratios with each other. ... Why is the ratio of 235U to 238U in uranium ore deposits so constant almost everywhere on Earth? One very precise study showed that the ratio is 0.0072842, with a standard deviation of only 0.000017. [There's less than one U235 atom, with its 700M year half-life, for every hundred U238s, with their 4.5B year half-lives.] Obviously, the more time that elapses between the formation of the various isotopes (such as 235U and 238U) and the farther they are transported to their current resting places, the more varied those ratios should be. The belief that these isotopes formed in a supernova explosion millions of light-years away and billions of years before the Earth formed and somehow collected in small ore bodies in a fixed ratio is absurd. Powerful explosions would have separated the lighter isotopes from the heavier isotopes. Some radioisotopes simultaneously produce two or more daughters. When that happens, the daughters have very precise ratios to each other, called branching ratios or branching fractions. Uranium isotopes are an example, because they are daughter products of some even heavier element. Recall that the Proton-21 Laboratory has produced superheavy elements that instantly decayed. Also, the global flux of neutrons during the flood provided nuclei with enough neutrons to reach their maximum stability. Therefore, isotope ratios for a given element are fixed. Had the flux of neutrons originated in outer space, we would not see these constant ratios worldwide. Because these neutrons originated at many specific points in the globe-encircling crust, these fixed ratios are global. - Waltbrownium, the IUPAC, and the Nobel Prize in Physics: The element that decayed into daughter products U-235 and U-238 is the naturally occurring though now-extinct waltbrownium. Symbol Wb. Atomic number (Z) 184. Atomic weight of > 473.07. 184 protons. > 289 neutrons. Solid at Earth's crustal temperatures and pressures. Half-life perhaps ~10 ns. Waltbrownium is the heaviest chemical element discovered (though indirectly) and therefore atop the post-Actinoid series. Wb is not [yet] an IUPAC officially named element but has been preliminarily named, here, by RSR. The identification of this element should earn its discoverer a Nobel Prize in Physics after he identified the evidence for its existence and the experimental evidence for its formation. The uniform uranium ratio provides the evidence to confirm that waltbrownium existed on the Earth. (This evidence provides as much, or even more, confirmation as neutrinos provide for solar fusion.) Further, the thousands of Proton-21 Laboratory experiments in the Ukraine (and in the U.S. at Sandia Nat'l Labs, Russia,

Today the Periodic Table is nicely filled out with 118 elements, but don’t be fooled--the search is on for element 119. The question is, do we have the tools to discover it? And, if we do, what might it be like? In this episode of Orbitals, we celebrate the International Year of the Periodic Table by chatting about the exciting possibilities with IUPAC executive director Dr. Lynne Soby and researcher Dr. Dawn Shaughnessy, who has five elemental discoveries on her CV. Written and hosted by Samantha Jones, PhD

Velaquí, por primeira vez en galego e cos 118 elementos actuais, a Canción dos Elementos interpretada ao vivo no Teatro Principal de Santiago por César Goldi (voz) e Manuel Riveiro Piano na Gala "Férveche a mente" o 30-9-17. Hai moitas versións da "The Element Song" de Tomas Lehrer. A orixinal só contaba con 102 elementos. En español destaca a de Nacha Guevara. So coñecemos unha versión actualizada aos 118 elementos actuais aprobados pola IUPAC o 28 de novembro de 2016, a de Helen Arney. Bea Fariñas fíxonos os seguintes apuntamentos a ter en conta: - Os gases nobres con sufixo -on (neon, argon, cripton, xenon, radon e oganesson) en galego teñen acentuación grave, isto é, non se acentúan graficamente por ser graves rematadas en -n e pronúncianse /néon/, /árgon/, /crípton/ etc. - roentgenio e seaborgio pronúncianse coma g suave, como se se escribisen "roentguenio" e "seaborguio" (non se escriben así para respectar o antropónimo orixinario). - O elemento de n. at. 117 en galego é ténesso Para o nome en galego dos elementos botamos man desta táboa da RSEQ confeccionada polo grupo "CienciaNosa" https://2.bp.blogspot.com/-yP1cZ0C7hYg/WMgK1bEkyqI/AAAAAAAABH4/3PORkia9i581ieCm5KF5x1g065M7kbrsQCLcB/s1600/tabla%2Bperiodica%2Ben%2Bgalego%2B2017.png

Bea Fariñas fíxonos os seguintes apuntamentos a ter en conta: - Os gases nobres con sufixo -on (neon, argon, cripton, xenon, radon e oganesson) en galego teñen acentuación grave, isto é, non se acentúan graficamente por ser graves rematadas en -n e pronúncianse /néon/, /árgon/, /crípton/ etc. - roentgenio e seaborgio pronúncianse coma g suave, como se se escribisen "roentguenio" e "seaborguio" (non se escriben así para respectar o antropónimo orixinario). - O elemento de n. at. 117 en galego é ténesso Para o nome en galego dos elementos botamos man desta táboa da RSEQ confeccionada polo grupo "CienciaNosa" https://2.bp.blogspot.com/-yP1cZ0C7hYg/WMgK1bEkyqI/AAAAAAAABH4/3PORkia9i581ieCm5KF5x1g065M7kbrsQCLcB/s1600/tabla%2Bperiodica%2Ben%2Bgalego%2B2017.png

Iniciamos 2016 con 4 novos inquilinos oficiais na táboa periódica. Son elementos artificiais radioactivos de vida tan efémera que nalgúns casos só se preparou un so átomo! Logo de anos de verificacións a IUPAC decidiu completar a sétima fila da táboa periódica. O catedrático emérito de Química Inorgánica da USC Manolo Bermejo cóntanos todo o que hai atrás destes descubrimentos.

Napoleon-Komplex Abgesehen davon, dass Napoleon durchaus nicht von kleiner Statur war, ist umstritten ob es den sogenannten Napoleon-Komplex tatsächlich gibt. Er beschreibt einen theoretischen Zustand bei Männern von kleinem Wuchs, denen übermäßige Aggressivität und dominantes Sozialverhalten zugeschrieben wird. Die Englische Zeitung "The Telegraph" zieht aus einer Studie der Oxford University den Schluss, dass es den Napoleon-Komplex tatsächlich gibt. Es wird beim Lesen der Studie nicht so recht klar, wie man zu dieser Behauptung gelangen kann. Immerhin wurde die Studie ausschließlich mit weiblichen Testpersonen durchgeführt, die Symptome von Verfolgungswahn haben. Bei dem Experiment mussten die Teilnehmerinnen eine Zugfahrt in einer Virtuellen Umgebung machen. In zwei Durchläufen wurde die Kunstwelt jeweils so angepasst, dass das Empfinden der eigenen Körpergröße einmal verkleinert und einmal normal war. Danach wurden die Testpersonen dazu befragt, ob sie sich beobachtet oder bedroht vorkamen oder den Eindruck hatten, die anderen Fahrgäste hätten sich gegen sie verschworen. Bei kleiner als normal empfundener Körpergröße fühlten die Testpersonen sich stärker verfolgt. Dabei war der Effekt stärker, wenn die Reihenfolge erst normal und danach verkleinert war. Die 7. Reihe des Periodensystems An wen muss man sich eigentlich wenden, wenn man mal ein neues Chemisches Element entdeckt hat? Hüter des Periodensystems der Element ist die International Union of Pure and Applied Chemistry (IUPAC), deren Sitz sich in USA befindet. Welche Elemente es in Zukunft zu entdecken lässt sich anhand der Ordnungszahlen theoretisch erschließen. Dementsprechend gibt es Elemente die vorübergehende Namen haben, die eben der Ordnungszahl entsprechen. So hat das Element 113 derzeit den Namen Ununtrium (eins-eins-drei). Jetzt hat das IUPAC die Entdeckung der Elemente 113, 115, 117 und 118 anerkannt. Die neuen Elemente dürfen jetzt dauerhafte Namen bekommen. Auch für die Benennung gibt es Regeln. Infrage kommen Namen aus folgenden Bereichen: Mythologischer Begriff Mineral Ort oder Land Eigenschaft Wissenschaftler Typischerweise werden Namen toter Wissenschaftler verwendet. Die einzige Ausnahme ist das Seaborgium, dass noch zu seinen Lebzeiten im Jahr 1997 nach Glenn T. Seaborg benannt wurde. Bei den Elementen der 7. Reihe des Periodensystems handelt es sich um Superschweren Elemente, die allesamt nur für den Bruchteil einer Sekunde existieren ehe sie in andere Elemente zerfallen. In der Natur kommen sie nicht vor. Sie werden künstlich hergestellt, indem man leichtere Kerne mit großer Geschwindigkeit aufeinanderprallen lässt. Das Ununtrium (113) wurde von Kosuke Morita am Reiken Institute in Japan entdeckt. Die Elemente 115, 117, 118 konnte ein Russisch-Amerikanisches Forscherteam aus Dubna und Kalifornien nachweisen. http://www.theguardian.com/science/2016/jan/04/periodic-tables-seventh-row-finally-filled-as-four-new-elements-are-added Drogen Welche Rauschmittel sind eigentlich am schädlichsten? In der medizinischen Fachzeitschrift "The Lancet" ist kürzlich eine Studie erschienen, welche die Schädlichkeit von Rauschmitteln bewertet. Mit Mitteln des Centre for Crime and Justice Studies haben Wissenschaftler ein Bewertungsmodell mit 16 Kriterien entwickelt, um die Schädlichkeit auf einer Skala von 0 bis 100 Punkten einzuordnen. Unterschieden wird Schädlichkeit für den Konsumenten und Schädlichkeit für andere. Dabei wird feiner untergliedert, zwischen unmittelbare Schäden durch die Substanz selbst und mittelbare Schäden etwa HIV-Infektionen bei Heroinkonsumenten durch kontaminierte Injektionsnadeln. Die mit Abstand schädlichste Substanz ist demnach Alkohol, gefolgt von Heroin und Crack. Most dangerous Drug (IFLScience) und das Lancet-Paper Angesichts der schädlichen Wirkung von Rauschgiften stellt sich die Frage, wie Gesellschaften damit umgehen sollen. Der bisherige Weg ist angesichts der britischen Studie inkonsequent, da die schädlichste aller Drogen frei verkäuflich ist, während, von Tabak abgesehen, die weniger schädlichen allesamt verboten sind. Bei Cannabis gibt es vereinzelt Ansätze einer Legalisierung. Bereits 2009 schrieb das englische Wirtschaftsmagazin "The Economist", dass der erbitterte Kampf gegen Drogen völlig wirkungslos geblieben ist, obwohl er Unsummen an Geld verschlingt. Tatsächlich nützt das Verbot von Rauschmitteln am meisten den kriminellen Organisationen, die auf den Schwarzmarkthandel spezialisiert sind. Mit einem Jahresumsatz von etwa 320 Dollar rangiert dieses Geschäft in der Größenordnung eines mittleren Mineralölkonzerns. Wie eigentlich seit dem Ende der Alkoholprohibition in den USA bekannt ist, hat das Verbot einer Substanz keinen nennenswerten Einfluss auf den Handel und Konsum davon. Die Kriminalisierung führt aber dazu dass die Qualität und Reinheit der konsumierten Substanzen nicht kontrollierbar ist und somit die Schädlichkeit des Konsums unnötig verstärken. Weiterhin führt sie dazu dass die Konsumenten im Verborgenen agieren, was sie häufig daran hindert Hilfsangebote anzunehmen. Dabei zeigen Versuche, beispielsweise in Portugal, dass die Legalisierung von Rauschmitteln nicht zu einem gesteigerten Konsum führt.

Mythos des Monats, die Wahrheit Sind Kupfermünzen überhaupt aus Kupfer? (Magnetversuch, 94,35 % Fe, 5,65 % Cu) Pflanzen brauchen Elemente C, O, H, Makronährstoffe N, K, Mg (Magnesium), Ca, S, P und Spurenelemente aus dem Boden, Fe, Zn (Zink), Co, Cl, B, Mo, Mn und tatsächlich Cu! Elementares Cu kann aus der Münze durchs H2O aufgenommen werden und die Zellwände stabilisieren. Cu wirkt fungizid. Oligodynamischer Effekt wie Ag.

Lo sciopero di domani della scuola spiegato bene dai prof. Orgoglio Chimica Donna: due ricercatrici italiane si aggiudicano il prestigiosissimo IUPAC 2015

An overview of organic chemistry, beginning with a discussion of the nature of organic compounds, the history of vitalism and its influence on the development of organic chemistry, and what makes carbon so special. I then discuss some important concepts in organic chemistry, including IUPAC nomenclature, functional groups, aromaticity, fullerenes, polymers, and organic synthesis. Recommended prelistening is Episode 15: Chemical Bonding, and Episode 23: Chemical Reactions.

Can Chemistry be the solution to face the challenge of diminishing drinking water supplies worldwide? Does the water we drink differ in different regions around the world? IUPAC and UNESCO have developed a set of experiments (acidity, salinity, filtration, distillation) for pupils of different ages to analyze the quality of water and learn how to treat their local water sources. Children all around the world will have the opportunity to upload the results of their investigations to an official website, making this initiative a Global Chemistry Experiment, and eventually, the biggest chemistry experiment ever.
