I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#New solar material could clean drinking water” With Army funding researchers at the University of Rochester have developed an aluminum panel that angled at the sun purifies water. Credit: Courtesy of University of Rochester Providing clean water to soldiers in the field and citizens around the world is essential, and yet one of the world’s…
“#Long-term heat-storage ceramics absorbing thermal energy from hot water” First-principles calculations of formation energies. (A) Periodic table colored by the total electronic energies of λ-Ti3O5 with an elemental substitution. Blue elements are those where substituted λ-Ti3O5 shows a lower formation energy than that of pure λ-Ti3O5. Orange elements are those where substituted λ-Ti3O5 shows a…
“#Spinning chemicals for faster reactions” Credit: CC0 Public Domain Cardiff University scientists have devised a new way of making reactions up to 70 times faster by using state-of-the-art equipment to spin chemicals around. They found that efficient mixing within a chemical reaction could be achieved by spinning chemicals and catalysts around in a small tube,…
“#Liquid crystals create easy-to-read, color-changing sensors” PME scientists and engineers have developed a way to stretch and strain liquid crystals to generate different colors. This could be applied in smart coatings, sensors, and wearable electronics. Credit: Oleg Lavrentovich, Liquid Crystal Institute, Kent State University Chameleons are famous for their color-changing abilities. Depending on their body…
“#Microscopy technique reveals nanoscale detail of coatings as they dry” Lehigh University researchers saw a “tempest in a teapot” as they observed the microstructure evolution of colloid-polymer film during the drying process. Credit: Kaewpetch, T., Gilchrist, J.F./Lehigh University Dull. Slow. Unchanging. Like watching paint dry. But take a closer look at that paint—all the way…
“#Polarization of bromine molecule in vanadium oxide cluster cavity and new alkane bromination” Peak of the spectrum due to polarized bromine molecule. Credit: Kanazawa University Alkanes are major constituents of natural gas and oil, consisting of carbon and hydrogen atoms only. The C-H bonds of alkanes are chemically stable with low reactivity. Technologies that enable…
“#Reducing the operating temperature of ceramic fuel cells with a high proton conductivity electrolyte” Design of the NCO/CeO2 heterostructure functionalities for fast proton migration. Credit: Science (2020). DOI: 10.1126/science.aaz9139 A team of researchers affiliated with several institutions in China has developed a way to reduce the operating temperature of ceramic fuel cells by using a…
“#Research on seawater surface tension becomes international guideline” Surface tension is the property of water that enables bugs to skim the surface of water. Research by John Lienhard and Kishor Nayar to understand how the surface tension of seawater changes with temperature and salinity has become an international standard. Credit: Christopher Paul High The property…
“#To engineers’ surprise, radiation can slow corrosion of some materials” These optical and scanning electron microscope images show irradiated and unirradiated zones of a nickel-chromium alloy. The left side shows examples of foils with irradiation; instead of degrading the material as it almost always does, the radiation actually makes it stronger by reducing the rate…
“#Liquid water is more than just hydrogen-oxygen molecules” Infrared spectra of light (red), heavy (blue), semiheavy (gray) water, and ionic species that have been identified in the current study. Red, white and black circles depict oxygen, hydrogen and deuterium atoms, respectively. Arrows show the directions of species vibrational deformation.
