Podcast appearances and mentions of louis brus

Is it possible to 'see' quantum mechanics in action? In a podcast conversation, chemistry laureate Moungi Bawendi speaks about the incredible gratification of visualising quantum mechanics and how his collaboration with co-laureate Louis Brus started. He also shares his love of music and speaks about how his lab's yearly ski trip helps his group work better together. Intuition and diversity in science are two more topics that are up for discussion. Hosted on Acast. See acast.com/privacy for more information.

Some words of wisdom from chemistry laureate Louis Brus: "You recognise opportunity and then you have to take advantage of it. Seize the opportunity basically. It takes some struggle." In a conversation with podcast host Adam Smith, Louis Brus speaks about the process of discovery and his own scientific path. Hosted on Acast. See acast.com/privacy for more information.

Here we discuss the discovery of quantum dots, those small particles hovering between molecule-size and macroscopic-size. We begin with physicist and refugee from Nazis Herbert Fröhlich, whose predictions led the way in the 1930s. Among the researchers we encounter are Aleksei Yekimov, Louis Brus, and Moungi Bawendi. Quantum dots were real, but could they be made reliably of specific sizes? The answer turned out to be yes, but you have to carefully control the conditions to make them.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

Imagine a particle so small that it's the same relative size to a soccer ball as that football is to the planet Earth. That's the size of a quantum dot – a type of nanocrystal that changes colour depending on its size, and was once thought impossible to actually make. Now, three scientists who helped discover and synthesise these quantum dots have been awarded the 2023 Nobel prize in chemistry.In this week's episode we speak to Louis Brus, one of these new Nobel laureates, and an emeritus professor of chemistry at Columbia University in New York, about his work on quantum dots and what winning the accolade means.

Three scientists in the United States won the Nobel Prize in Chemistry on Wednesday. The three won for their discovery of quantum dots, a technology widely used today to make displays for electronic devices and medical imaging. 周三，美国三名科学家荣获诺贝尔化学奖。 三人因发现量子点而获奖，量子点是一种当今广泛用于制造电子设备和医学成像显示器的技术。 The Royal Swedish Academy of Sciences awarded the prize to Moungi Bawendi of the Massachusetts Institute of Technology, Louis Brus of Columbia University in New York, and Alexei Ekimov of Nanocrystals Technology. 瑞典皇家科学院将该奖授予麻省理工学院的 Moungi Bawendi、纽约哥伦比亚大学的 Louis Brus 和纳米晶体技术公司的 Alexei Ekimov。 The academy said the three were honored for their work with particles that “have unique properties and now spread their light from television screens and LED lamps.” 该学院表示，这三人因其在粒子方面的工作而受到表彰，这些粒子“具有独特的特性，现在可以从电视屏幕和 LED 灯中传播光线”。 LED lights are electronic lights used all over the world, which use energy very effectively. LED灯是世界各地使用的电子灯，其能源利用效率非常高。 Pernilla Wittung Stafshede, a member of the Nobel committee that awarded the prize, said, “We have displays on TVs, in your cellphone, that use quantum dots inside...” 诺贝尔奖颁奖委员会成员佩尼拉·维通·斯塔夫谢德 (Pernilla Wittung Stafshede) 表示：“我们在电视、手机上都有显示屏，里面使用了量子点……”Quantum dots are extremely small particles, called nanoparticles. They are said to be about 1/10,000 the width of a human hair. The dots glow blue, red, green or other colors when exposed to light. The color they give off depends on the size of the particles. Larger dots look red, and smaller dots look blue. The color change is caused by the behavior of electrons in these small spaces. 量子点是极小的颗粒，称为纳米颗粒。 据说它们的宽度约为人类头发的 1/10,000。 当暴露在光线下时，这些点会发出蓝色、红色、绿色或其他颜色的光。 它们发出的颜色取决于颗粒的大小。 较大的点看起来是红色的，较小的点看起来是蓝色的。 颜色的变化是由电子在这些小空间中的行为引起的。 Physicists had predicted these color-change properties as early as the 1930s. However, it took 50 years of research and development to control the size of quantum dots correctly. 早在 20 世纪 30 年代，物理学家就预测了这些变色特性。 然而，人们花了50年的研发时间才正确控制量子点的尺寸。 Ekimov and Brus were the early researchers of the technology. Bawendi is credited with developing the production of quantum dots being used today. Ekimov 和 Brus 是该技术的早期研究人员。 巴文迪因开发了当今使用的量子点的生产而受到赞誉。 Bawendi used the words, “very surprised, sleepy, shocked, unexpected and very honored,” to describe his feelings. Bawendi added he was not thinking about the possible uses of his work when he started researching quantum dots. 巴文迪用“非常惊讶、困倦、震惊、意外和非常荣幸”来形容他的感受。 巴文迪补充说，当他开始研究量子点时，他并没有考虑他的工作的可能用途。 “The motivation really is the basic science. A basic understanding, the curiosity of how does the world work? And that's what drives scientists and academic scientists to do what they do,” he said. “动机确实是基础科学。 对世界如何运作的基本了解和好奇心？ 这就是驱使科学家和学术科学家去做他们所做的事情的动力，”他说。 Brus of Columbia University said he did not answer the phone call from the Swedish academy. He finally saw the news online when he got up in the morning. 哥伦比亚大学布鲁斯表示，他没有接听瑞典科学院的电话。 早上起床的时候，他终于在网上看到了这条新闻。 Brus said the practical uses of quantum dots, like creating the colors in TV screens, are something he was hoping for when he started the work many years ago. 布鲁斯说，量子点的实际用途，比如在电视屏幕上创造颜色，是他多年前开始这项工作时所希望的。 “Basic research is extremely hard to predict exactly how it's going to work out,” Brus said. “It's more for the knowledge base than it is for the actual materials. But in this case, it's both.” “基础研究很难准确预测其结果，”布鲁斯说。 “这更多的是为了知识库而不是实际材料。 但在这种情况下，两者都是。” Ekimov is the former chief scientist at Nanocrystals Technology, a company based in New York where he started working in 1999. The Swedish academy credited him with showing how the size of nanoparticles affected the colors in glass. Ekimov 是纽约 Nanocrystals Technology 公司的前首席科学家，他于 1999 年开始在纽约工作。瑞典科学院称赞他展示了纳米颗粒的尺寸如何影响玻璃的颜色。The three will receive 11 million Swedish crowns, about $1 million, and a gold medal when they collect their Nobel Prizes at the award ceremonies in December. 三人在 12 月的颁奖典礼上领取诺贝尔奖时将获得 1100 万瑞典克朗（约合 100 万美元）和一枚金质奖章。

El Nobel de Química de este año no ha estado exento de polémica tras producirse una supuesta filtración en la que se daban como galardonados a tres científicos, Moungi Bawendi, Louis Brus y Alexei Ekimov, todos ellos vinculados a universidades estadounidenses. Finalmente, parece que la filtración ha sido una realidad, ya que el Premio Nobel de Química 2023 ha premiado el descubrimiento y desarrollo de puntos cuánticos, nanopartículas tan diminutas que su tamaño determina sus propiedades de los anteriormente mencionados científicos.

O francês Moungi Bawendi, o americano Louis Brus e o russo Alexei Ekimov foram anunciados como os vencedores do Prêmio Nobel de Química em 2023 pela descoberta e pelo desenvolvimento de pontos quânticos, nanopartículas tão pequenas que o seu tamanho determina as suas propriedades. Essas partículas estão em televisores e lâmpadas LED, e também podem orientar os cirurgiões na remoção de tecidos tumorais, entre muitas outras aplicações. A professora Beate Saegesser Santos (UFPE), com 20 anos de pesquisas em pontos quânticos, explica a ciência premiada e comenta essa edição do Prêmio Nobel.

En el programa de hoy repasamos los tres premios Nobel de ciencias que se han hecho públicos hace unos días. Dedicamos unos minutillos a cada uno de ellos, en este orden: - El Nobel de Química 2023 ha galardonado a Moungi Bawendi, Louis Brus y Alexei Ekimov por el descubrimiento y el desarrollo de técnicas para sintentizar *puntos cuánticos*, unos pequeños cristales cuyas propiedades físicas y químicas dependen de su tamaño. - El Nobel de Medicina 2023 ha tenido poca sorpresa: Katalin Karikó y Drew Weissman por las técnicas de modificación del ARN que hicieron posible el desarrollo de vacunas de ARN. - El Nobel de Física 2023 ha premiado a Pierre Agostini, Ferenc Krausz y Anne L'Huillier por inventar las técnicas que han permitido generar pulsos de *attosegundos*, que a su vez están permitiendo estudiar el movimiento y la dinámica de electrones individuales dentro de átomos y moléculas. Tres premios muy merecidos, todos ellos presentes en las "quinielas" que hacemos todos los años y a los que podríamos dedicar un programa completo, pero en ausencia de ello al menos os los resumimos para que sepáis por dónde han ido los tiros. Si queréis saber más sobre el Nobel de Medicina le acabamos de dedicar un programa completo en nuestro pódcast hermano, Aparici en Órbita: buscad el episodio s06e02. También podéis aprender más sobre las vacunas de ARN aquí, en La Brújula de la Ciencia, en el programa que hicimos cuando estaban empezando a distribuirse, en 2021: se trata del capítulo s10e21.

Descubrimiento de clusters atómicos, conocidos como "quantum dots", gana el Premio Nobel de Química 2023. Aplicaciones transforman tecnología actual.El mundo científico ha sido testigo de una revelación impactante. Moungi Bawendi, un químico de ascendencia francesa y tunecina, afincado en el prestigioso MIT; Louis Brus, renombrado profesor emérito en la Universidad de Columbia; y Aleksey Ekimov, nacido en la Unión Soviética y ahora líder en Nanocrystals Technology en Nueva York, han recibido conjuntamente el reconocido Nobel de Química 2023. Su inigualable aportación al descubrimiento de clusters atómicos, bautizados como "quantum dots", ha marcado un antes y un después en la nanotecnología. Esta invención es la piedra angular de notables avances en la visualización de pantallas modernas y en herramientas vanguardistas en el ámbito médico.La nanotecnología, un mundo fascinante en escala atómica, ha revelado sorpresas con el descubrimiento de los "quantum dots". Estos pequeños clusters, comparables en relación de tamaño a un balón de fútbol con la Tierra, se utilizan hoy en día para añadir colores vivos a las pantallas planas, iluminación LED y herramientas médicas avanzadas.Aunque el impacto de los "quantum dots" es innegable, la trayectoria no ha sido sencilla. El camino hacia su descubrimiento estuvo plagado de escepticismo. Durante años, muchos se preguntaron si valía la pena invertir en el control de materiales a tan pequeña escala.A pesar de los desafíos, el trabajo pionero de estos científicos ha demostrado ser invaluable. Desde su introducción en la industria multimillonaria de las televisiones hasta su aplicación en bioimágenes, los "quantum dots" han transformado nuestra forma de ver y entender el mundo en la escala nanométrica.

"This is a collaborative effort," says Louis E. Brus when asked for his first reaction to the award of the 2023 Nobel Prize in Chemistry, "partly physics, partly chemistry, partly material science." In this conversation with the Nobel Prize's Adam Smith he pays tribute to the many contributors to the field and discusses his own motivations for exploring the nature of nanoparticles in the productive environment of Bell Labs, 40 years ago. "It's a surprise, at this point, after all these years," he says, "I'm just lucky, I guess, that the Nobel Prize has chosen to honour this particular areas of research at this time." Hosted on Acast.

On the version of Hot off the Wire posted Oct. 4 at 6:50 a.m. CT: WASHINGTON (AP) — The House of Representatives has entered uncharted territory after the success of a last-ditch, right-wing effort to remove fellow Republican Kevin McCarthy from the speakership. A resolution called a motion to vacate was brought forward by Florida Republican Rep. Matt Gaetz and passed Tuesday with the support of eight Republicans and every Democrat present. The effort makes McCarthy the first speaker in history to be removed from office. McCarthy's subsequent announcement he would not run for the job again clears the path for any Republican to jump in. Some members, including Gaetz, have been broaching potential consensus candidates like Majority Leader Steve Scalise or Whip Tom Emmer who they believe could bring the conference together. STOCKHOLM (AP) — Three scientists have won the Nobel Prize in chemistry for their work on quantum dots. Those are tiny particles that can release very bright colored light and are used in electronics and medical imaging. Moungi Bawendi, Louis Brus and Alexei Ekimov were honored Wednesday for their work with the particles just a few atoms in diameter and that spread their light from television screens and LED lamps. Quantum dots' electrons have constrained movement, and this affects how they absorb and release visible light, allowing for very bright colors. WASHINGTON (AP) — President Joe Biden has announced another $9 billion in federal student loan debt forgiveness. The relief will be provided through existing programs. The details were provided by the White House on Wednesday. Biden has been under pressure to fulfill his promises on student debt relief even though his original plan was overturned by the conservative majority on the Supreme Court. In total, 3.6 million borrowers will have had $127 billion in debt wiped out since the Democratic president took office. The White House says Biden believes college should be a ticket to the middle class, not a burden weighing on families. Republicans have fought Biden's plans on student debt. BALTIMORE (AP) — Officials say at least five people have been wounded, none critically, in a shooting at Morgan State University in Baltimore that happened as students were headed to a homecoming week campus ball. A shelter-in-place order was lifted around 12:30 a.m. Police Commissioner Richard Worley said the five victims, four men and one woman, are between the ages of 18 and 22, but police released no information on suspects and said they did not know how many shooters were involved. Morgan State University President David Wilson said he had canceled Wednesday's classes, and would hold an emergency meeting Wednesday morning to decide whether to hold other homecoming week events. ALBANY, N.Y. (AP) — New York City Mayor Eric Adams says he's traveling to Latin America to discourage people from seeking asylum in the city as it struggles to handle a massive influx of migrants. The Democratic mayor detailed the trip in a news conference Tuesday. He says he wants to give an honest assessment of the situation and tell people in the region that the city's shelter system has been overwhelmed and is at capacity. Adams has made a series of urgent pleas for a shift in federal immigration policy and for funding to help the city manage the arrival of migrants. VENICE (AP) — A bus carrying dozens of people plummeted 50 feet from an elevated road in Venice, causing a fiery crash that killed 21 people and injured at least 15 mostly foreign tourists returning to a nearby campsite. Those who died in the crash Tuesday night included at least four Ukrainians and a German citizen, according to Venice prefecture. At least two of the dead were children. The new, electric bus was carrying foreign tourists when it fell from an elevated street on Tuesday evening, catching fire. The driver was killed. A Venice city councilor said he was an experienced driver and local prosecutors are investigating if he felt ill. The Rangers and Twins win their American League Wild Card openers, while the Diamondbacks and Phillies do the same in the National League. On the version of Hot off the Wire posted Oct. 3 at 3:30 p.m. CT; updated at 4 p.m. CT: WASHINGTON (AP) — House Speaker Kevin McCarthy has been voted out of the job in an extraordinary showdown, a first in U.S. history. The 216-210 vote was forced by a contingent of hard-right conservatives and throws the House and its Republican leadership into chaos. McCarthy's chief rival, Rep. Matt Gaetz of Florida, brought forward the “motion to vacate,” drawing together more than a handful of conservative Republican critics of the speaker and many Democrats who say he is unworthy of leadership. Next steps are uncertain, but there is no obvious successor to lead the House Republican majority. NEW YORK (AP) — A judge has imposed a limited gag order on President Donald Trump after he disparaged a key court staffer during his civil business fraud trial. Judge Arthur Engoron issued the order Tuesday. The order applies to all parties in the case and pertains only to verbal attacks on court staff. It came after Trump recirculated a disparaging social media post about Engoron's principal law clerk, Allison Greenfield. Trump then deleted the post. WILMINGTON, Del. (AP) — Hunter Biden has pleaded not guilty in Delaware to three federal firearms charges filed after the implosion of an earlier deal to resolve a long-running investigation. The California resident's Tuesday plea sets the case on a track toward a possible trial in 2024 while President Joe Biden is running for reelection. The Democratic president's son has been charged with lying about his drug use in 2018 on a form to buy a gun he kept for about 11 days. He could face up to 25 years in prison if convicted. A judge asked Hunter Biden if he understood the charges against him, and Biden replied: “Yes, Your Honor.” WASHINGTON (AP) — The White House says President Joe Biden has been in touch with U.S. allies and partners to discuss continued support for Ukraine in its fight against Russia. Tuesday's conversation came after Biden signed legislation late Saturday to keep the U.S. government funded. The bill did not include billions in aid for Ukraine that he had requested. The Republican-controlled House dropped the Ukraine aid request as a concession to growing opposition among GOP lawmakers. Poland's president told reporters after the call that Biden assured the leaders that backing exists for continuing U.S. support to Ukraine. TAIPEI, Taiwan (AP) — Taiwan has issued a weather alert as Typhoon Koinu is approaching and may make landfall later this week, bringing gales and downpours to the southeastern parts of the island. The weather bureau put out a land warning on Tuesday after issuing a sea alert late Monday. Koinu was moving northwest with sustained winds of 101 mph near its center, according to the bureau. Forecasters expected it to bring strong winds and downpours to southern and eastern parts of Taiwan early Wednesday and potentially make landfall in the southeastern part of the island on Thursday. WASHINGTON (AP) — Former union leader and Democratic insider Laphonza Butler has been sworn in as the newest member of the U.S. Senate, replacing California Sen. Dianne Feinstein after her death and becoming only the third Black female senator in history. Butler was appointed by California Gov. Gavin Newsom on Sunday, just two days after Feinstein died at her home in Washington. Butler is a longtime fundraiser and strategist in the state's Democratic circles and was the head of Emily's List, a national organization that raises money for women candidates who support abortion rights. Butler was sworn in by Vice President Kamala Harris, who served as the second Black female senator. Donald Trump's campaign is calling on the Republican National Committee to cancel all remaining presidential primary debates. In a statement late Monday, top Trump advisers say the RNC must instead “refocus its manpower” on defeating Joe Biden next year. The statement also repeats debunked falsehoods about election fraud, claiming without evidence that Democrats are working to steal the 2024 election. Trump has maintained the lie that the 2020 election was stolen, despite multiple legal cases, investigations and his own attorney general finding no fraud. The RNC didn't immediately respond to requests for comment. Rival Ron DeSantis' campaign says Trump should show up to debate and that the U.S. “needs a president who will fight for them anywhere, in any forum.” TORONTO (AP) — An official says India has told Canada to remove 41 of its 62 diplomats in the country, ramping up a confrontation over Canadian accusations that India may have been involved in the killing of a Sikh separatist leader in suburban Vancouver. The official spoke on condition of anonymity ahead of public reaction from the Canadian government later Tuesday. The official confirmed an earlier report from the Financial Times. Canadian Prime Minister Justin Trudeau has said there were “credible allegations” of Indian involvement in the slaying of Hardeep Singh Nijjar, a 45-year-old Sikh leader who was killed by masked gunmen in June WASHINGTON (AP) — The National Zoo's three giant pandas are set to return to China in December with no public signs the 50-year-old exchange agreement struck by President Richard Nixon will continue. There are diplomatic tensions between China and a number of Western governments. And China appears to be gradually pulling back its pandas from Western zoos as their agreements expire. The departure of the bears from the nation's capital would mean the only giant pandas left in America are at the Atlanta Zoo — and that agreement expires next year. Panda-philes visiting the Washington zoo say they're making plans to visit Atlanta next summer to see those pandas before they leave. DENVER (AP) — Colorado's highest court says it will hear the case of a Christian baker who refused to make a cake celebrating a gender transition. The decision announced Tuesday comes after a U.S. Supreme Court victory this summer for a graphic artist who didn't want to design wedding websites for same-sex couples. Baker Jack Phillips won a partial victory before the U.S. Supreme Court in 2018 in another case after refusing to make a gay couple's wedding cake. He was later sued by a transgender woman after he refused to make her cake to celebrate her gender transition. WASHINGTON (AP) — U.S. Rep. Henry Cuellar of Texas is back at work after being carjacked by three armed attackers less than a mile from the Capitol. Cuellar said Tuesday he was “good” and even joked about the frightening experience, saying his car was recovered but what really upset him was that they had taken his sushi. The Democrat says the robbers “came out of nowhere" and pointed guns at him. Monday night's carjacking is the second assault on a member of Congress in the District of Columbia this year. In February, Minnesota Democrat Angie Craig was assaulted in her apartment building. Craig suffered bruises while escaping serious injury. DETROIT (AP) — Stellantis is recalling nearly 273,000 trucks in the U.S. because the radio software can stop the rear view camera image from being displayed. The recall announced Tuesday by U.S. safety regulators covers certain Ram 1500 pickup trucks and some Ram 3500 chassis cabs from the 2022 and 2023 model years. Also covered are 2022 through 2024 Ram 2500 trucks. The National Highway Traffic Safety Administration says a rear view display without an image reduces a driver's view and increases the risk of a crash. Dealers will update the radio software at no cost to owners, who will be notified by letter starting Nov. 17. WASHINGTON (AP) — The Army is launching a sweeping overhaul of its recruiting to focus more on young people who've spent time in college or are job hunting early in their careers. The Army's aim is to reverse years of enlistment shortfalls. A major part of this is the formation of a new professional force of recruiters instead of relying on soldiers assigned to the task. Army Secretary Christine Wormuth tells The Associated Press some of the changes will begin in the next 90 days but a wholesale transformation to turn around years of decline is several years in the making. Wormuth says the Army hasn't met its annual goal for new enlistment contracts since 2014. DETROIT (AP) — The Michigan Supreme Court has turned down an appeal and cleared the way for the parents of the Oxford High School shooter to face trial on involuntary manslaughter charges. James and Jennifer Crumbley are accused of making a gun available to Ethan Crumbley and ignoring his mental health needs. The state appeals court in March said the couple could face trial, and the Supreme Court says it will let that decision stand. Ethan Crumbley killed four fellow students and injured seven other people at Oxford High in November 2021. A judge last week said he's eligible for life in prison without parole. —The Associated Press About this program Host Terry Lipshetz is a senior producer for Lee Enterprises.
