For application as a pseudocapacitor electrode, highly porous CoO nanowalls are fabricated directly on 3D macroporous nickel foam (see images). A relatively high areal capacitance is achieved because of the structure. By grafting with another pseudocapacitive oxide, can be further significantly boosted, owing to increased surface area caused by hierarchically structure well possible synergetic effect between two oxides.

The effect of Na3(PO3)3 on the growth KDP crystal (101) faces was studied by Michelson interference technique and atomic force microscopy. experimental results show that rates were near zero at low supersaturation when doped into solution, i.e., there a interval similar to "growth dead zone". began increase rapidly as crossed zone" continued increase. increased doping concentration increased. In addition, anisotropy hillocks decreased competition became more intense gradually in solution...

Abstract Multi‐focal lenses are widely applied in zoom imaging, parallel laser processing, 3D displays, among others. However, conventional refractive or diffractive elements cannot realize independently switchable multi‐focal points at arbitrary spatial positions. The ultra‐thin metasurface provides a compact solution while the commonly used interleaved meta‐units scheme deteriorates performance of meta‐devices. Here authors propose all‐dielectric noninterleaved metalenses with...

Abstract Heat shock protein 90 ( H sp90) is a highly conserved chaperone that interacts with various client proteins to mediate their folding and stability. The Broad‐Complex‐Tramtrack‐Bric‐a‐brac (BTB) domain, also known as poxvirus zinc finger (POZ) exists widely in different conserved. However, the stability mechanism of BTB domain‐containing has not been fully understood. Co‐immunoprecipitation pull‐down assay were performed investigate interaction between sp90 transcription factor B...

Abstract Manipulation of wavefront lies at the core next‐generation information technologies. Compared to metal and dielectric metasurfaces, atomic 2D materials exhibit excellent prospects toward fulfilling ultra‐thin thickness requirements in flat optics shaping, with much smaller than those traditional bulky devices. However, phase manipulation by light propagating through is suppressed due its sub‐nanometer thickness. Here, an approach reported realize reflection singularities...
