Abstract The electrochemical conversion of nitrate to ammonia is a way eliminate pollutant in water. Cu-Co synergistic effect was found produce excellent performance generation. However, few studies have focused on this high-entropy oxides. Here, we report the spin-related nitrate-to-ammonia using oxide Mg 0.2 Co Ni Cu Zn O. In contrast, Li-incorporated MgCoNiCuZnO exhibits inferior performance. By correlating electronic structure, that spin states are crucial for pair with high O can...
The potential of water (photo)electrolysis technology to provide hydrogen as a fuel on large scale depends how viable electrocatalysts for the oxidation reaction (WOR) and evolution (HER) are whether they can be constructed from elements which abundant in Earth's crust. Here we show that ternary sulfides cobalt–tungsten nickel–tungsten (MWSx where M is Co or Ni) efficient robust HER over wide pH range. These novel were readily grown conducting electrode surface by employing scalable...
The construction of viable photoelectrochemical (PEC) devices for solar-driven water splitting can be achieved by first identifying an efficient independent photoanode oxidation and a photocathode hydrogen generation. These two photoelectrodes then must assembled with proton exchange membrane within complete coupled system. Here we report the preparation Si/a-CoMoSx hybrid which shows impressive performance (onset potential 0.25 V vs RHE photocurrent jsc 17.5 mA cm–2 at 0 RHE) in pH 4.25...
Abstract The forkhead box (FOX), FOXO1 and FOXO3, transcription factors regulate multiple functions in mammalian cells. Selective inactivation of the Foxo1 Foxo3 genes murine ovarian granulosa cells severely impairs follicular development apoptosis causing infertility, as shown here, cell tumor (GCT) formation. Coordinate depletion suppressor Pten gene Foxo1/3 strain enhanced penetrance onset GCT Immunostaining Western blot analyses confirmed phosphatase tensin homolog (PTEN) depletion,...
The role of the hedgehog (HH) signaling pathway in ovarian function was examined transgenic mice which expression a dominant active allele signal transducer smoothened (SmoM2) directed to ovary and Müllerian duct by cre-mediated recombination (Amhr2(cre/+)SmoM2). Mutant were infertile had reproductive tract defects. Ovaries contained follicles all sizes corpora lutea (CL), but oocytes rarely recovered from oviducts superovulated remained trapped preovulatory follicles. Measures luteinization...
Abstract In this work, the step‐wise oxidation mechanism of nickel (Ni) nanowires is elucidated. Rapid vacancy diffusion plays a significant role at low temperatures in forming heterostructures oxide (NiO) nanotubes with Ni nanowires. Subsequent investigations nanowire higher and faster temperature ramp rates show that it difficult to bypass rapid stage, which affects formation final structure. Therefore, unlikely form solid NiO or uniform wall thickness through conventional...

A scalable method to load a cobalt-oxide-phosphate (CoPi) water oxidation electrocatalyst onto the surface of mesoporous graphitic-carbon-nitride (mpg-CNx) semiconductor is reported. This procedure resulted in significant enhancement photocatalytic activity mpg-CNx oxidation. The optimal loading gave an oxygen evolution rate up approximately 1 mmol O2 gcat−1 h−1 under 100 mW cm−2 visible light illumination pH 7 phosphate buffer containing Ag+ or Na2S2O8 as electron scavenger which was 400...
A new catalyst, prepared by a simple physical mixing of ruthenium (Ru) and tungsten (W) powders, has been discovered to interact synergistically enhance the electrochemical hydrogen evolution reaction (HER). In an aqueous 0.5 M H2SO4 electrolyte, this which contained miniscule loading 2-5 nm sized Ru nanoparticles (5.6 μg per cm2 geometric surface area working electrode), required overpotential only 85 mV drive 10 mA/cm2 H2 evolution. Interestingly, our catalyst also exhibited good immunity...
Cobalt oxide for oxygen evolution reaction (OER) often suffers from over-oxidation and structural instability under alkaline conditions. We develop erbium (Er)-doped CoO microspheres with the assistance of L-aspartic acid, which show superior OER activity stability by leveraging electron supply effect Er to optimize structure prevent over-oxidation.
Molybdenum oxide (MoO3) is a promising anode buffer layer (ABL) for high-performance organic photovoltaic (OPV) devices. However, the reasons enhanced performances remain unclear. In this work, we show that defect states play an important, if not dominating, role in improving OPV performances. The changes both density of and work function MoO3 with annealing are shown correlated device performance. increased densities improve performance through hole extraction rate at MoO3/organic...
The structural and optical properties of sputter deposited nitrogen (N) doped CuO (CuO(N)) thin films are systematically investigated. It is found that the incorporation N into causes an enlargement bandgap reduction in resistivity CuO(N) films. Furthermore, a gradual phase transformation from to Cu2O observed with increase concentration. effects annealing temperature on its dependence concentration also process significantly depends temperature. Heterojunction solar cells p-type n-type...
Using the small polaron model, we show clearly that oxygen vacancy defects are detrimental to electrochromic responses of molybdenum oxide (MoO3). The observed phenomenon is explained by studying oxidation states (Mo) metal, which central site specific model. First, used pair explain red-shift between absorption peak induced and inserted lithium (Li). Next, any Mo5+ results in either a poor cathodic optical pair, or forms inactive for Li insertion. main reason latter due inability generate...
The instability of isolate catalysts during metal-assisted chemical etching is a major hindrance to achieve high aspect ratio structures in the vertical and directional silicon (Si). In this work, we discussed showed how catalyst motion can be influenced controlled by semiconductor doping type oxidant concentration ratio. We propose that triggering event deviating brought about unequal etch rates across catalyst. This indirectly affected through rates. While events are stochastic, offers...
Abstract In this work, we investigate the transport processes governing metal-assisted chemical etching (MacEtch) of silicon (Si). We show that in oxidation Si during MacEtch process, hole charges can be accomplished by diffusion metal ions. The is subsequently governed a redox reaction between ions and Si. This represents fundamentally different proposition whereby such understood to occur through carrier conduction followed injection into (or electron extraction from) Consistent with ion...
Abstract The Hendra and Nipah viruses (HNVs) are highly pathogenic pathogens without approved interventions for human use. In addition, the interaction pattern between attachment (G) fusion (F) glycoproteins required virus entry remains unclear. Here, we isolate a panel of Macaca-derived G-specific antibodies that cross-neutralize HNVs via multiple mechanisms. most potent antibody, 1E5, confers adequate protection against challenge in female hamsters. Crystallography demonstrates 1E5 has...
