Copper nanoparticles/fluorine-doped tin oxide (FTO) nanocomposites were successfully prepared by a simple hydrothermal method. The synthesized nanocomposites were characterized by X-ray diffraction (XRD), UV-visible diffuse-reflectance spectrum (UV-VIS DR... see more

In this paper, the new photocatalyst, Ptx-/TiO2-yBy was prepared by impregnation method via coupling with a inorganic water splitting system, namely, a ternary system K+,Na+/B4O72- - H2O for hydrogen evolution. The integration process of the preparation f... see more

The highly efficient electrochemical hydrogen evolution reaction (HER) provides a promising way to solve energy and environment problems. In this work, various transition metals (Fe, Co, Ni, Cu, Ag, and Pt) were selected to support on molybdenum carbides ... see more

Developing bi-functional electrocatalysts for both oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) is crucial for enhancing the energy transfer efficiency of metal–air batteries and fuel cells, as well as producing hydrogen wit... see more

Chicken meat has a high nutrient content. However, its quality is easy to be degraded. The degradation is normally characterized by the formation of metabolite gases (NH3 and H2S) as deterioration indicators. Sensors detect phenomena better than human sen... see more

In this paper, we propose to numerically simulate the spatial-temporal (axial and radial) evolution of the density of certain nitrogen oxides present in the gaseous mixture: 74% N2, 10% O2, 8% H2O and 8% CO2 which is subject to a negative corona discharge... see more

The 17q21.31 band is one of the most structurally complex and evolutionary dynamic regions of the genome. Frequencies of two single nucleotide polymorphisms (SNPs): rs9468 and rs1800547 determine worldwide distribution of H1 and H2 haplotypes. Recent stud... see more

The influence of polyacrylamide (PAA; Mn between 5·103 and 1.5·106 gmol-1 ) on hydrogen evolution reaction at the polycrystalline gold in 0.5 M H2SO4 was studied using potentiodynamic measurements (5 mV/s) in the potential range from 0 to -0.6 V/she. It w... see more

The aim of this paper was to establish the seasonal evolution of the microclimate factorslevel in several shelters from Turda Zoo. Four sets of measurements were made (in summer, autumn,winter and spring) in different places: the cage and the paddock of t... see more
