Points matter when designing nanoparticles that drive important chemical reactions using the power of light, according research from Rice University's Laboratory for Nanophotonics.
Professor James Rondinelli's new design criteria for enhancing the spin lifetime of a class of quantum materials could support Internet of Things devices and other resource-intensive technologies.
Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic resonance, magnetization patterns can be made visible. When using increasingly intense pulses, however, the magnetization image fades away. The mechanism responsible for this loss in resonant magnetic scattering intensity has now been clarified.
Studies indicate that homemade masks help combat the spread of viruses like COVID-19 when combined with frequent hand-washing and physical distancing. Many of these studies focus on the transfer of tiny aerosol particles; however, researchers say that speaking, coughing and sneezing generates larger droplets that carry virus particles. Because of this, mechanical engineer Taher Saif said the established knowledge may not be enough to determine the effectiveness of some fabrics used in homemade masks.
Additive free, multimaterial 3D printing is achieved for milk-based products without temperature control
In summary, a comprehensive temperature-dependent electrical transport, Raman scattering, synchrotron XRD, and DFT study has been carried out to understand the effect of external pressure on perovskite NaOsO3.
The National Institute of Information and Communications Technology has developed a unique superconducting hot electron bolometer mixer (HEBM) using magnetic materials. The 2 THz band HEBM produced this time has a low noise performance of about 570 K (DSB), which is about 6 times the quantum noise limit, and a wide IF band characteristic of about 6.9 GHz, which is about 3 GHz larger than the conventional structure HEBM. Both of these are world-class performance.
Researchers at the Max Born Institute (MBI) have shown that high-resolution movies of molecular dynamics can be recorded using electrons ejected from the molecule by an intense laser field.
Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go? In a new study, a Monash-led team has for the first time confirmed what actually happens to those calcium atoms. Surprising everyone, the calcium goes underneath both the upper graphene sheet and a lower 'buffer' sheet, 'floating' the graphene on a bed of calcium atoms.
The criteria for comparing virtual and actual clothes was clarified, which will be useful for future utilization of 3D simulators for garment production.
