Solution-processed nickel oxide passivation on large-area silicon electrodes for efficient photoelectrochemical water splitting.

Photoelectrochemical water splitting is a promising technology for converting solar energy into chemical energy. For this system to be practically viable, the materials and processes employed for photoelectrode fabrication should be cost-effective and scalable. Herein, we report the large-scale fabrication of nickel oxide-coated n-type silicon (n-Si) photoanodes chemical bath deposition for efficient photoelectrochemical water oxidation.

What is the prevalence of developmental prosopagnosia? An empirical assessment of different diagnostic cutoffs.

The prevalence of developmental prosopagnosia (DP), lifelong face recognition deficits, is widely reported to be 2-2.5%. However, DP has been diagnosed in different ways across studies, resulting in differing prevalence rates.

Effect of Chitosan Coating for Efficient Encapsulation and Improved Stability under Loading Preparation and Storage Conditions of Lipopeptides.

This study aims to evaluate the effect of chitosan coating on the formation and properties of cyclic lipopeptide (CLP)-loaded liposomes. A nanoencapsulation strategy for a chitosan-coated liposomal system using lecithin phospholipids for the entrapment of antibiotic CLP prepared from KB21 was developed. The produced chitosan-coated CLP liposome had mean size in the range of 118.

Brain region-specific regulation of histone acetylation and efflux transporters in mice.

Multidrug resistance protein 1 (MDR1) and breast cancer resistance protein (BCRP) protect the brain by restricting the passage of chemicals across the blood-brain barrier. Prior studies have demonstrated the epigenetic regulation of MDR1 and BCRP in cancer cells treated with histone deacetylase (HDAC) inhibitors that enhance histone acetylation and gene transcription. In the present study, we tested the in vivo effects of two HDAC inhibitors, valproic acid (VPA; 400 mg/kg) and apicidin (5 mg/kg), on Mdr1 and Bcrp transporter expression in brain regions of adult male mice injected intraperitoneally daily for 7 days.

Enhanced Photocatalytic Performance Depending on Morphology of Bismuth Vanadate Thin Film Synthesized by Pulsed Laser Deposition.

We have fabricated high quality bismuth vanadate (BiVO) polycrystalline thin films as photoanodes by pulsed laser deposition (PLD) without a postannealing process. The structure of the grown films is the photocatalytically active phase of scheelite-monoclinic BiVO which was obtained by X-ray diffraction (XRD) analysis. The change of surface morphology for the BIVO thin films depending on growth temperature during synthesis has been observed by scanning electron microscopy (SEM), and its influence on water splitting performance was investigated.

Peptoid helicity modulation: precise control of peptoid secondary structures via position-specific placement of chiral monomers.

The degree of peptoid helicity can be effectively modulated by position-specific incorporation of α-chiral aromatic monomers. In this study, we report the structural role of each monomer position collected from 30 comprehensive model peptoid oligomers demonstrating a meticulous manner to fine-tune peptoid secondary structures.
