Researchers from Sandia National Laboratories have identified a big hurdle to progressing solid-state lithium-ion battery performance in small electronics: the movement of lithium ions across battery interfaces.
Scientists have created a water cloaking concept hinged on electromagnetic forces that has the ability to eliminate the wake of an object, thereby considerably minimizing its drag while at the same time assisting it in evading detection.
A study, carried out by EPFL, reports that adding guanidinium into perovskite solar cells stabilizes their efficiency at 19% for 1000 hours under full-sunlight testing circumstances. Details of the study have been published in Nature Energy.
UC Berkeley physicists state that an individual’s physical attraction to hot bodies is real. To be clear, the physicists are not talking about sexual attraction towards a “hot” human body. However, the researchers have demonstrated that a glowing object in fact attracts atoms, opposing to what most people – including physicists– would guess.
For more than six and a half decades, niobium boride (NbB) has been regarded a typical example of a superconducting material. This presumption has been noted down in manuals related to physics of condensed matter and scientific articles journals, and has at present been challenged in a research carried out by scientists from the University of São Paulo (USP), Brazil, and from San Diego State University, United States.
Following the starting signal, two electrons speed off in opposite directions. The one that wins the race is hardly seven attoseconds (7x10-18 seconds) ahead. It has been impossible to measure the difference till now as it is very small. However, that difference is brought about by chirality, a hallmark of molecules responsible for emitting electrons.
Metallic lithium tends to get deposited on the anodes when lithium-ion batteries are charged very rapidly. This lowers battery capacity and lifespan and can even damage the batteries.
Investigations of nonlinear phenomena of magneto-plasmonic waveguides is enthralling because of their basic significance as well as their prospective use in integrated nanoplasmonic devices for manifold usability in chip-scale plasmonic communication systems.
According to a study performed at University of Limerick (UL), Ireland, mobile phone speakers and motion detectors in video games and cars may soon be powered by electricity produced from low cost and sustainable biomaterials.
Dentists depend on composite materials in order to carry out restorative procedures, such as filling cavities. However, these materials, such as tooth enamel, can be susceptible to the growth of plaque, referring to the sticky biofilm that causes tooth decay.
