source:azomLimitations of Conventional P-N Junction Solar CellsThe efficiency of traditional p-n junction solar cells is limited to 31% - 41% depending on the sunlight concentration. Moreover, expensive crystalline silicon modules are used for the production of p-n junction solar cells, which makes these PV materials economically unviable for power harvesting applications compared to other energy generation sources.Significance of Low Band Gap FE Materials for Solar Cell ApplicationsLow bandgap ferroelectric (FE) materials have gained significant attention from the scientific community due to ...

Effect of an enamel matrix derivative (Emdogain) on the microhardness and chemical composition of human root dentin: an in vitro study source：natureAbstractThe advantage of using an Enamel matrix derivative EMD Emdogain as an intracanal medication could be a manner to strength the tooth structure, improving the physical and chemical properties of dentin. We tested, in vitro, the effect of Emdogain on the surface microhardness and chemical composition of root dentin. Ten human teeth were used to produce dentin specimens originated from the canal walls (n = 30) that remained in contact to E...

source:analyticsinsightAt the U.S. DOE Argonne National Laboratory, researchers achieved quantum coupling of tiny magnetsElectrons are teeny tiny magnets. Tiny magnets can be utilized for connections in corrective devices or for holding together replacement dentures where several teeth are absent. They have a north and a south pole and spin around an axis. When coated tiny magnets can work effectively and have an increased resistance to corrosion. Quantum computers are machines that use the properties of quantum physics to store data and perform computations.Quantum computing is a quickly aris...
