Nitrogen-Doped Porous Nickel Molybdenum Phosphide Sheets for Efficient Seawater Splitting.

Hydrogen is emerging as an alternative clean fuel; however, its dependency on freshwater will be a threat to a sustainable environment. Seawater, an unlimited source, can be an alternative, but its salt-rich nature causes corrosion and introduces several competing reactions, hindering its use. To overcome these, a unique catalyst composed of porous sheets of nitrogen-doped NiMo P (N-NiMo P) having a sheet size of several microns is designed.

Investigation of electroencephalography variations of mental workload in the exposure of the psychoacoustic in both male and female groups.

Therefore, this study was performed with the aim of investigating the brainwave in the face of psychoacoustic and the change of difficulty level of task. 120 persons were exposed to 16 psychoacoustic parameters (loudness, sharpness, roughness and fluctuation strength).

Surface-Enhanced Raman Spectroscopy Substrates for Food Safety and Quality Analysis.

Surface-enhanced Raman spectroscopy (SERS) has been identified as a fundamental surface-sensitive technique that boosts Raman scattering by adsorbing target molecules on specific surfaces. The application of SERS highly relies on the development of smart SERS substrates, and thus the fabrication of SERS substrates has been constantly improved. Herein, we investigate the impacts of different substrates on SERS technology including plasmonic metal nanoparticles, semiconductors, and hybrid systems in quantitative food safety and quality analysis.

Effect of the preparation method on activity of Cu-ZSM-5 nanocatalyst for the selective reduction of NO by NH.

The selective catalytic reduction of NO with ammonia (NH-SCR) was studied over Cu-ZSM-5 nanocatalysts which were prepared by several methods, including conventional ion-exchange (IE), conventional impregnation (IM), ultrasound-enhanced impregnation (UIM), and conventional deposition-precipitation (DP) using NaOH and homogeneous deposition-precipitation (HDP) using urea.
