Crystallography for the misfit crystals

Advanced algorithms plus an exceptional X-ray laser can reveal the structures of not-so-neat-and-tidy materials unattainable by other techniques

24-Jan-2022

Francis Crick, who famously co-discovered the shape of DNA, once said: “If you want to understand function, study structure.” Many decades later, this remains a tenet of biology, chemistry, and materials science. A key breakthrough in the quest for DNA’s structure came from X-ray crystallography, ...

On the line: Watching nanoparticles get in shape

New method could advance next-generation applications in medicine, cosmetics, and petroleum recovery

26-Feb-2021

Liquid structures - liquid droplets that maintain a specific shape - are useful for a variety of applications, from food processing to cosmetics, medicine, and even petroleum extraction, but researchers have yet to tap into these exciting new materials' full potential because not much is known ...

New algorithm sharpens focus of world's most powerful microscopes

Scientists develop a technique that improves the resolution of cryo-electron microscopy

09-Oct-2020

We've all seen that moment in a cop TV show where a detective is reviewing grainy, low-resolution security footage, spots a person of interest on the tape, and nonchalantly asks a CSI technician to "enhance that." A few keyboard clicks later, and voila - they've got a perfect, clear picture of ...

X-rays uncover a hidden property that leads to failure in a lithium-ion battery material

Experiments at SLAC and Berkeley Lab uproot long-held assumptions and will inform future battery design

19-Sep-2018

Over the past three decades, lithium-ion batteries, rechargeable batteries that move lithium ions back and forth to charge and discharge, have enabled smaller devices that juice up faster and last longer. Now, X-ray experiments at the Department of Energy's SLAC National Accelerator Laboratory ...

Splitting water: Nanoscale imaging yields key insights

20-Jul-2018

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel - just as plants do - researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may ...

Mapping nanoscale chemical reactions inside batteries in 3-D

06-Mar-2018

Researchers from the University of Illinois at Chicago and Lawrence Berkeley National Laboratory have developed a new technique that lets them pinpoint the location of chemical reactions happening inside lithium-ion batteries in three dimensions at the nanoscale level. "Knowing the precise ...

Google provides open source library for quantum chemistry

Platform-independent solution to integrate future developments

26-Oct-2017

Since physicists have been dealing with the theoretical description of molecules, the solving of quantum mechanical equations has been a major obstacle. This is supposed to be a thing of the past with the release of an open source based system. Google has introduced such a system to the public ...
