redOrbit Staff & Wire Reports - Your Universe Online Researchers are one step closer to solving the mysteries of graphene, the carbon allotrope that could be the basis for the next generation of sensors, transistors, processors and more - if scientists can find a way to produce it in large quantities and mold it into the shape necessary to power future devices. One of the major problems with the material is that it is difficult to grow it into a layer that is only a single atom...

Gold-plated Fossil Cleanup
2012-05-24 07:27:54

A team from the University of Leicester has solved a long-standing problem in fossil research, and their novel approach will assist in the study of ancient specimens. Fossils are often coated with a very thin layer of gold to study the specimens under an electron microscope. The gold brings out otherwise invisible details. When the analysis is complete the fossils need to be returned to their natural state. However, the removal of the gold has always been difficult, expensive, and uses...

First Atomic-Scale Real-Time Movies Of Platinum Nanocrystal Growth In Liquids

Berkeley Scientists Create Graphene Liquid Cells for Electron Microscopy Studies of Nanocrystal Formation [ Watch the Video ] They won´t be coming soon to a multiplex near you, but movies showing the growth of platinum nanocrystals at the atomic-scale in real-time have blockbuster potential. A team of scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a technique for encapsulating liquids of...

Looking into specimens on an atomic level in liquids, and understanding atomic processes so far regarded impossible The Korea Advanced Institute of Science and Technology (KAIST) announced that a research team from the Department of Materials Science and Engineering has developed a technology that enables scientists and engineers to observe processes occurring in liquid media on the smallest possible scale which is less than a nanometer. Professor Jeong Yong Lee and Researcher Jong Min...

Sandia National Laboratories is using its Ion Beam Laboratory (IBL) to study how to rapidly evaluate the tougher advanced materials needed to build the next generation of nuclear reactors and extend the lives of current reactors. Reactor operators need advanced cladding materials, which are the alloys that create the outer layer of nuclear fuel rods to keep them separate from the cooling fluid. Better alloys will be less likely to deteriorate from exposure to everything from coolant fluids...

UCLA researchers are now able to peer deep within the world's tiniest structures to create three-dimensional images of individual atoms and their positions. Their research, published March 22 in the journal Nature, presents a new method for directly measuring the atomic structure of nanomaterials. "This is the first experiment where we can directly see local structures in three dimensions at atomic-scale resolution – that's never been done before," said Jianwei (John) Miao, a...

Some Bacteria Attack Using Poison Daggers
2012-02-27 10:00:41

[ Watch the Video ] Bacteria have evolved different systems for secreting proteins into the fluid around them or into other cells. Some, for example, have syringe-like exterior structures that can pierce other cells and inject proteins. Another system, called a type VI secretion system, is found in about a quarter of all bacteria with two membranes. Despite being common, researchers have not understood how it works. Now a team, co-led by researchers at the California Institute of...

Researchers from the University of York are pioneering the development of electron microscopes which will allow scientists to examine a greater variety of materials in new revolutionary ways. The team, headed by Professor Jun Yuan and Professor Mohamed Babiker, from the University´s Department of Physics has created electron beams with orbital angular momentum — electron vortex beams — which will open the way to many novel applications including the more efficient...
