Although several new optical storage technologies, such as multiwavelength optical storage, holographic optical storage, super-resolution optical storage, and near-field optical storage, have been developed, these technologies require sophisticated manipulation and expensive equipment, which restricted their use in many practical applications.Photochromism has gained significant attention as an effective optical st...

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...

source:scienceAbstractThe study of subtle effects on transport in semiconductors requires high-quality epitaxial structures with low defect density. Using hybrid molecular beam epitaxy (MBE), SrTiO3 films with a low-temperature mobility exceeding 42,000 cm2 V−1 s−1 at a low carrier density of 3 × 1017 cm−3 were achieved. A sudden and sharp decrease in residual resistivity accompanied by an enhancement in the superconducting transition temperature were observed across the second Lifshitz transition where the third band becomes occupied, revealing dominant intraband scattering. These films ...
