We report a facile and large-scale fabrication of three-dimensional (3D) ZnO/CuO heterojunction branched nanowires (b-NWs) their application as photocathodes for photoelectrochemical (PEC) solar hydrogen production in neutral medium. Using simple, cost-effective thermal oxidation hydrothermal growth methods, b-NWs are grown on copper film or mesh substrates with various ZnO CuO NWs sizes densities. The characterized detail using high-resolution scanning transmission electron microscopies...
We report the fabrication of a three dimensional branched ZnO/Si heterojunction nanowire array by two-step, wafer-scale, low-cost, solution etching/growth method and its use as photoelectrode in photoelectrochemical cell for high efficiency solar powered water splitting.

The NiOx film has three functions: (i) serves protection layer to improve the chemical stability Si photoelectrode, (ii) acts an oxygen evolution catalyst, and (iii) provides junction photovoltage further reduce overpotential. onset potential is reduced below thermodynamic oxidation level was observed at...

The photoelectrodes show orders magnitudes higher photocurrent compared to bare electrodes. More interestingly, selective photoelectrochemical cathodic or anodic behavior resulting in either oxidation reduction was achieved by tuning doping concentration p-type core. Specifically,...
We report the systematic study of 3D ZnO/Si branched nanowire (b-NW) photoelectrodes and their application in solar water splitting. focus our on correlation between electrode design structures (including Si NW doping, dimension trunk branch ZnO NWs, b-NW pitch size) photoelectrochemical (PEC) performances (efficiency stability) under neutral conditions. Specifically, we show that for electrodes with lightly doped p-Si core, larger branches longer cores give a higher photocathodic current,...
We studied the thin film heterojunction photodiode made of nickel oxide (NiO) and zinc (ZnO) deposited by low cost energy-efficient sol–gel spin coating. The highly visible-transparent with a smooth interface gives rise to good photoresponse quantum efficiency under ultra-violet (UV) light illumination.

Principal component analysis (PCA) is an important and widely used unsupervised learning method that determines population structure based on genetic variation. Genome sequencing of thousands individuals usually generate tens millions SNPs, making it challenging for PCA interpretation. Here we present VCF2PCACluster, a simple, fast memory-efficient tool Kinship estimation, clustering analysis, visualization VCF formatted SNPs. We implemented five estimation methods three its users to choose...
Despite considerable advances in retinal prostheses over the last two decades, resolution of restored vision has remained severely limited, well below 20/200 acuity threshold blindness.
