HOXD10 attenuates renal fibrosis by inhibiting NOX4-induced ferroptosis.

In chronic kidney disease (CKD), renal fibrosis is an unavoidable result of various manifestations. However, its pathogenesis is not yet fully understood. Here, we revealed the novel role of Homeobox D10 (HOXD10) in CKD-related fibrosis.

Free-triplet generation with improved efficiency in tetracene oligomers through spatially separated triplet pair states.

Singlet fission (SF) can potentially boost the efficiency of solar energy conversion by converting a singlet exciton (S) into two free triplets (T + T) through an intermediate state of a correlated triplet pair (TT). Although efficient TT generation has been recently realized in many intramolecular SF materials, their potential applications have been hindered by the poor efficiency of TT dissociation. Here we demonstrate that this can be overcome by employing a spatially separated (T…T) state with weak intertriplet coupling in tetracene oligomers with three or more chromophores.

Pressure effects on the structures and electronic properties of halide perovskite CsPbX (X = I, Br, Cl).

Cesium lead halide perovskites as ideal photovoltaic and optoelectronics materials have attracted more and more attention. Here, we investigated the structure and electronic properties of halide perovskite CsPbX (X = I, Br, Cl) by particle swarm optimization and first principles methods at hydrostatic pressure. For CsPbI, the structure phases and corresponding phase transitions of non-perovskite orthorhombic Pnma (non-Pv-Pnma), monoclinic C2/m (C2/m-I), and another different monoclinic phase C2/m (C2/m-II) are found in the pressure range 0-120 GPa.

The exchange bias behavior of BiFeO nanoparticles with natural core-shell structure.

The surface and interface effects of small antiferromagnetic nanostructures are important on the modulation of their magnetic properties. In this report, temperature and particle size dependent magnetic exchange bias effect was investigated in BiFeO (BFO) nanoparticles that possess natural core-shell structure. Nonmonotonic variation of exchange bias field, interesting surface spin-glass state and improved exchange bias training effect are only obtained in 18 nm BFO particles.

Vapor-solid growth and characterization of aluminum nitride nanocones.

Aluminum nitride nanostructures are attractive for many promising applications in semiconductor nanotechnology. Herein we report on vapor-solid growth of quasi-aligned aluminum nitride nanocones on catalyst-coated wafers via the reactions between AlCl3 vapor and NH3 gas under moderate temperatures around 700 degrees C, and the growth mechanism is briefly discussed. The as-prepared wurtzite aluminum nitride nanocones grow preferentially along the c-axis with adjustable dimensions of the sharp tips in the range of 20-60 nm.
