New transmission microscope for low-energy electrons
Physicist Daniël Geelen (Leiden University) has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defended his Ph.D. thesis on May 31st.
Electron tomography technique leads to 3-D reconstructions at the nanoscale
Understanding the microscopic structure of a material is key to understanding how it functions and its functional properties. Advances in fields like materials science have increasingly pushed abilities to determine these ...
Novel technique achieves 32-fold increase in nanometric bactericide's activity
In recent decades, research groups in the field of materials science have invested time and resources to answer the following question: Is it possible to develop new techniques to produce silver particles on a nanometric ...
Liquid cell transmission electron microscopy makes a window into the nanoscale
From energy materials to disease diagnostics, new microscopy techniques can provide more nuanced insight. Researchers first need to understand the effects of radiation on samples.
Scientific challenges and opportunities for remediating radioactive waste
One of the nation's enduring scientific challenges has been to find effective ways of remediating millions of gallons of chemical and radioactive waste remaining from Cold War activities. Now a team of experts has combed ...
Efficient and high-throughput technique to study the structure of DNA
It may be the most famous structure in biology, but it wasn't until a few years ago that biophysicist Enzo di Fabrizio and his colleagues took the first direct images of the DNA double helix with an electron microscope.
Mapping battery materials with atomic precision
Lithium-ion batteries are widely used in home electronics and are now being used to power electric vehicles and store energy for the power grid. But their limited number of recharge cycles and tendency to degrade in capacity ...
Permian carbo-loading: How starchy treats helped build an ancient world
Everyone loves a nice plate of pasta. After all, starch is the ultimate energy food. Now, we have proof that carbo-loading has been a thing for at least 280 million years.
Bryozoans, brachiopods, and phoronida originate from the common ancestor
A biologist from Lomonosov Moscow State University has studied the nervous system of the adult phoronida using modern methods and presented new facts regarding the taxonomy of invertebrates, proving that phoronids, barchiopods ...
