Researchers from University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the XUV spectrum to generate second harmonics on a laboratory scale. As the team writes in Science Advances, they were able to achieve this effect for the first time with a laser source on a laboratory scale and thus investigate the surface of a titanium sample down to the atomic level.
Like water vapor on the bathroom mirror, gas molecules come together and condense into liquid droplets due to the attractive forces between them. In a study published in Nature Physics, researchers have discovered that active particles can condense by turning and moving toward crowded areas.
Scanning technology aimed at detecting small amounts of nuclear materials was unveiled by scientists in Sweden today, with the hope of preventing acts of nuclear terrorism.
Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) developed a new approach to determine the best electrode materials composition for Solid-state lithium-ion batteries. The research group of St. Petersburg Polytechnic University developed a method to determine the electrochemical capacity of each component of the "nickel-cobalt oxide" system.
So far, only a handful of siRNA, or other RNA interference-based therapeutics that can shut down harmful genes to keep viruses from spreading have been approved. Chemical engineering researchers in the Cockrell School of Engineering have created several nanoparticles to help solve the problem of getting the siRNA into the body and guiding it to the target.
The University of Kent's School of Physical Sciences, in collaboration with the Science and Technology Facilities Council (STFC) and the Universities of Cardiff, Durham and Leeds, have developed an algorithm to train computers to analyse signals from subatomic particles embedded in advanced electronic materials.
New sensors developed by Professor Otto Gregory, of the College of Engineering at the University of Rhode Island, and chemical engineering doctoral student Peter Ricci, are so powerful that they can detect threats at the molecular level.
The demonstration that a tiny cloud of atoms can be turned from a heat engine into a cooler by cranking up the interactions between the particles provides both deep fundamental insight and a possible template for more efficient thermoelectric devices.
A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an analysis of the proton mass radius in Physical Review D on May 11. The proton mass radius is determined to be 0.67 ± 0.03 femtometers, which is obviously smaller than the charge radius of the proton.
University of Chicago Asst. Prof. Mark Levin and his team have discovered a way to create new molecules by cutting nitrogen atoms from molecules.
