First successful protein structural analysis in a levitating drop of liquid
Generally, in rechargeable batteries, lithium ions are transported by the electrolyte from the negative electrode to the positive electrode during the discharging process and the ionic flow path reverses during the recharging process.
Proteins are complex molecules that are responsible for carrying out all of the processes that sustain life. A better understanding of how these molecules perform their functions can be achieved by learning the assembly of their atoms and how the structure of this assembly changes as the atoms react. Until now, no imaging technique has allowed the observation of molecular movement in such speed and detail.
Using a cooling technique developed by researchers at Harvard University, JILA physicists have improved the ability of their robust laser “combing” technique to determine the structures of large, complicated molecules present in pharmaceuticals, fuels, explosives, and the gases surrounding stars.
Researchers at the Johns Hopkins University report that each year, birth defects, surgery, or trauma have resulted in an estimated number of 200,000 people requiring bone replacement surgery in the face or head.
Molybdenum disulfide (MoS2) is used as an effective lubricant in motorcycle and aircraft engines, and in the universal and CV joints of automobiles and trucks. The material also exhibits a remarkable light absorption property, according to Isabell Thomann, an engineering researcher at Rice University. This quality makes molybdenum disulfide a potential candidate for the development of photocatalytic and optoelectronic devices.
All living cells are essentially soft and squishy balloons containing DNA, proteins, and a large amount of water. These cells are surrounded by oily membranes, which can withstand considerable amounts of stress like bending, stretching, and squeezing. It was only recently that researchers have started to understand the functions and organization resulting from that stress.
For the first time, researchers have successfully imaged all of the steps involved in a complicated organic reaction, and subsequently resolved the microscopic mechanisms that account for their behavior. The study was performed by an international team of scientists, including the UPV/EHU's Nano-Bio Spectroscopy Research Group.
With documented public water issues caused by corrosion in Hoosick Falls, New York, and Flint, Michigan, it is necessary to know the impact of corrosion on copper at the atomic level so that such issues can be avoided in future pipes. Corrosion-related damage costs represent 3% of the US Gross Domestic Product (roughly $503.1 billion, as per the values in 2013).
A group of researchers at Okayama University and Osaka University, Japan examined the state of the surface of apparently fixed powder beds in which air weak enough not to move the powder is injected, and observed anomalous sinking phenomena, a world first.
