By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers have reproduced with astonishing fidelity the luminous hues and subtle shadings of Girl With a Pearl Earring, Dutch artist Johannes Vermeer's masterpiece. • Email to a friend • Researchers propose a nano-confinement strategy to host multiple Fe and Cu single atoms inside the extremely narrow yet regular surface cavities of graphitic carbon nitride to form sub-nanometer reactors. • Email to a friend • The development of efficient electrocatalyst to produce molecular hydrogen from water is receiving considerable attention, in an effort to decrease our reliance on fossil fuels. Silver sulfide nanocrystals have attracted enormous interests due to its excellent properties. • Email to a friend • Scientists developed a method to generate circularly polarized light from the ultimate symmetrical structure: the sphere. Their approach involves breaking the inherent symmetry of the sphere by electron beam excitation, which allows for precisely controlling the phase and polarization of the emitted light. • Email to a friend • Researchers have demonstrated the use of elastic vibrations to manipulate the spin states of optically active color centers in SiC at room temperature. They show a non-trivial dependence of the acoustically induced spin transitions on the spin quantization direction, which can lead to chiral spin-acoustic resonances. • Email to a friend • The physicochemical properties of nanoparticles alone cannot predict the fate of nanoparticles in biological systems. Current evidence suggests that the formation of a corona on the nanoparticle surface is the most important parameter that controls nanoparticle toxicity. Scientists now showed that protein corona modulates internalisation and cytotoxicity of nanodiamonds in non-phagocytic and phagocytic cells. Specifically, they found that corona made of bovine serum albumin (BSA), which represents the most abundant protein in blood plasma, reduced nanodiamond agglomeration. • Email to a friend • |
