The development of bimetallic nanoparticles (i.e., tiny particles composed of two different metals that exhibit several new and improved properties) represents a novel area of research with a wide range of potential applications. Now, a research team in the University of Maryland (UMD)’s A. James Clark School of Engineering has developed a new method for

Agência FAPESP – Highly concentrated aqueous electrolytes, known as water-in-salt electrolytes, could be an alternative to the organic solvents used in car batteries and other electrochemical devices. Abundance and, hence, low cost are key factors in this application, alongside nontoxicity, according to the review article “Water-in-salt electrolytes for high voltage aqueous electrochemical energy storage devices”

To keep from getting caught in their own webs, these spiders use a nonstick comb on their back legs. Now, researchers reporting in

Electron spin–a fundamentally quantum property–is central to spintronics, a technology that revolutionized data storage,[1] and that could play a major role in creating new computer processors. In order to generate and detect spin currents, spintronics traditionally uses ferromagnetic materials whose magnetization switching consume high amounts of energy. In the April 22, 2020 issue of Nature,

Now,

When looking at a left hand in the mirror, it looks like a right hand. However, the left hand never overlaps the right hand. Such a geometrical relationship that an image of the object in a plane mirror cannot be brought to coincide with itself is called chirality. A clockwise or counterclockwise helical staircase is

Nanoengineers at the University of California San Diego are working on a COVID-19 vaccine using an unconventional candidate: a plant virus. The team’s goal is to use plants to create a stable, easy to manufacture vaccine that can be shipped around the globe. It will be packaged in slow-release microneedle patches that patients can wear

The team, led by physicists at the Technische Universität Kaiserslautern (TUK) in Germany and University of Vienna in Austria, generated the Bose-Einstein condensate (BEC) through a sudden change in temperature: first heating up quasi-particles slowly, then rapidly cooling them down back to room temperature. They demonstrated the method using quasi-particles called magnons, which represent the
