Scanning Electron Microscope is a sophisticated tool used in many fields of scientific research, even in ceramics.The use of an electron beam instead of light allows to get not only outstanding high resolution images but also detailed information on the composition of the sample.Insights are so accurate and exhaustive that offer manufacturers clear solutions or, at least, suggestions about the actions that should be taken to properly solve production critical issues.How does the tool work and what are its most important functions to support ceramic industry?

How much more of our world could we understand, if we could take stock of it, one atom at a time? If we could see the structure of individual molecules, understand the complex ways they interact with one another, and witness first-hand how they move? These are questions for electron microscopy, and more broadly, for Materials Science. Materials scientists peer into the atomic structure of the stuff that makes up our world, to figure out the relationships between the structure of a material, and its resulting properties. They study how to change materials at the molecular level, to improve the way they function in the real world. It's an interdisciplinary field that spans the physics and chemistry of matter, engineering, and industrial manufacturing. It's led to an enormous number of advances, from nanotechnology to aerospace engineering, pioneering medical innovations to quantum computing. And SOME of these advances are thanks to the work of Professor Colin Humphreys. As Professor of Materials Science at Queen Mary University of London, and Distinguished Research Fellow at the Department of Materials Science at the University of Cambridge, Colin works on materials with fascinating properties that would be hard to understand without delving into their atomic structure: semiconductors, superconductors, nanoparticles, and ultra-high temperature aerospace materials. He's also a committed student of Christianity and applies his scientific mind to questions of biblical scholarship: calculating the exact date of the crucifixion for example, or naturalistic explanations for miracles.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.08.19.256909v1?rss=1 Authors: Zhang, K., Pintilie, G. D., Li, S., Schmid, M. F., Chiu, W. Abstract: Breakthroughs in single-particle cryo-electron microscopy (cryo-EM) technology have made near-atomic resolution structure determination possible. Here, we report a ~1.35-Å structure of apoferritin reconstructed from images recorded on a Gatan K3 or a Thermo Fisher Falcon 4 detector in a commonly available 300-kV Titan Krios microscope (G3i) equipped with or without a Gatan post-column energy filter. Our results demonstrate that the atomic-resolution structure determination can be achieved by single-particle cryo-EM with a fraction of a day of automated data collection. These structures resolve unambiguously each heavy atom (C, N, O, and S) in the amino acid side chains with an indication of hydrogen atoms' presence and position, as well as the unambiguous existence of multiple rotameric configurations for some residues. We also develop a statistical and chemical based protocol to assess the positions of the water molecules directly from the cryo-EM map. In addition, we have introduced a B' factor equivalent to the conventional B factor traditionally used by crystallography to annotate the atomic resolution model for determined structures. Our findings will be of immense interest among protein and medicinal scientists engaging in both basic and translational research. Copy rights belong to original authors.

Structural biologists rejoiced when cryo–electron microscopy, a technique to generate highly detailed models of biomolecules, emerged. But years after its release, researchers still face long queues to access these machines. Science's European News Editor Eric Hand walks host Meagan Cantwell through the journey of a group of researchers to create a cheaper, more accessible alternative.   Also this week, host Joel Goldberg speaks with psychiatrist and researcher Goodman Sibeko, who worked with the Xhosa people of South Africa to help illuminate genetic details of schizophrenia. Though scientists have examined this subject among Western populations, much less is known about the underlying genetics of people native to Africa.   This week's episode was edited by Podigy.   Listen to previous podcasts.   About the Science Podcast

James Baughman uses his background in photography and chemistry to understand material failures, but he uses his imagination to see pictures in the electron microscope scans.

To make materials better, sometimes you have to start with a failure. And if you look hard enough, you can see art in the science.

This recording is from the  NorthWest Herb Symposium. Jay and Bridget Johnson of Tree Farm Communications host this excellent event each August in Coupeville, WA. Their next event is August 23rd - 26th, 2018.  LEARN MORE CLASS DESCRIPTION Epigenomics is the study of epigenetic changes in gene expression that occur without commensurate changes in DNA base pair sequences; these changes may be transmissible to subsequent generations. Recent research in the emerging field of Epigenomics strongly supports the probabilities of therapeutic transgenerational herbalism. Epigenomics is developing in response to research showing very convincingly that many cancers are initiated and controlled by transmissible extrachromosomal mechanisms. Ryan Drum, PhD has a BSc in Chemical Technology and a PhD in Botany (Phycology) from Iowa State University. While a NATO Scholar, he did postdoctoral studies on Cell Biology using the Electron Microscope and Microcine at the Universities of Bonn, Germany and Leeds, England. For 10 years he taught Botany and related subjects at Universities (UMASS/Amherst, UCLA, WWU). He studied Herbal Medicine with Ella Birzneck, founder of Dominion Herbal College in British Columbia for 12 years, and taught at their summer seminars for 35 years. He has been an adjunct faculty at Bastyr University since 1984, and he lectures at major herbal conferences and herbal schools. Dr. Drum is the author of over 30 scientific papers in peer-reviewed journals, the author of Electron Microscopy of Diatom Cells 1966, Springer Verlag, a 100-Plate Atlas, in print for 20 years, and a contributing author of two chapters in Planting the Future (Gladstar and Hirsch 2001) and a chapter in Fundamentals of Naturopathic Endocrinology, M.

Imagine a Where's Waldo book with nothing butblack and white pictures. Good luck using his candy-stripesweater as a visual cue. Now you know what it's like trying to find a virus on a greyscale microscopic image. Microbiologists have dealt with this problem for decades, because when things get small, things go dark. Photons, bits of light essential to discerning color, are too clunky to resolve anything much smaller than say, a synapse connecting two neurons.

I visited Arizona and spoke at the AZGroups event with Scott Guthrie and Brady Gaster. While I was there my friend Eric Herbrandson (you might remember him from ScratchAudio and Hanselminutes) invited my wife and the kids over to the AppFive offices to check out their Electron Microscope. This isn't a tiny microscope...it's huge but it looks at tiny things all using WPF software that's written by AppFive. Forgive the cell phone video, this was originally intended as just a bit of video for myself but I thought you guys might enjoy it as well.

This is an episode about electron microscopes with Bernard van Vlimmeren and Kees Kooijman of FEI Company. Among other things, we talk about the various kinds of electron microscopes, the components that go into electron microscopes, the important role of the sensors and a couple of example applications.

Are quarks the ultimate seeds of matter or is there a deeper layer of the Cosmic Onion? If there is, HERA, the most powerful electron microscope in the world, may be the first to know.

Purified mitochondrial ribosomes (60S) have been isolated from locust flight muscle. Purification could be achieved after lysis of mitochondria in 0.055 M MgCl2. Mitochondrial 60S and cytoplasmic 80S ribosomes were investigated by electron microscopy in tissue sections, in sections of pellets of isolated ribosomes, and by negative staining of ribosomal suspensions. In negatively stained preparations, mitochondrial ribosomes show dimensions of sim270 x 210 x 215 Å; cytoplasmic ribosomes measure sim295 x 245 x 255 Å. From these values a volume ratio of mitochondrial to cytoplasmic ribosomes of 1: 1.5 was estimated. Despite their different sedimentation constants, mitochondrial ribosomes after negative staining show a morphology similar to that of cytoplasmic ribosomes. Both types of particles show bipartite profiles which are interpreted as "frontal views" and "lateral views." In contrast to measurements on negatively stained particles, the diameter of mitochondrial ribosomes in tissue sections is sim130 Å, while the diameter of cytoplasmic ribosomes is sim 180–200 Å. These data suggest a volume ratio of mitochondrial to cytoplasmic ribosomes of 1:3. Subunits of mitochondrial ribosomes (40S and 25S) were obtained by incubation under dissociating conditions before fixation in glutaraldehyde. After negative staining, mitochondrial large (40S) subunits show rounded profiles with a shallow groove on a flattened side of the profile. Mitochondrial small subunits (25S) display elongated, triangular profiles.
