Delafossite CuFeO2 is a promising photocathode material for solar hydrogen production, but its performance low because of poor charge transport properties. When the prepared electrode annealed by hybrid microwave annealing (HMA), photoelectrochemical water reduction activity increases more than 4 times (−1.3 mA cm–2 @ 0.4 VRHE), while conventional thermal (CTA) improves only 2 (−0.62 @0.4 VRHE). The postannealing intercalates extra oxygen into lattice to form CuFeO2+1.5δ, which carrier...

A microwave-assisted hydrothermal synthesis produces ZnFe2 O4 containing Na residue as a precursor to CO2 hydrogenation catalyst that displays high conversion and selectivity liquid hydrocarbon products in the gasoline diesel range with olefin-to-paraffin ratios. Compared reference catalysts derived from Fe2 O3 ZnO-Fe2 physical mixture, -derived contains well-dispersed iron particles Zn serving structural promoter. profound effect of residual an electronic promoter is also observed, which...

Abstract The intestinal microbiota affect various physiological traits of host animals such as brain development, obesity, age, and the immune system. In swine industry, understanding relationship between growth stage is essential because directly related to feeding system pigs, thus we studied 32 healthy pigs across five sows at 10, 21, 63, 93, 147 d ages. were altered with separated into three distinct clusters. relative abundance several phyla genera significantly different stages. We...

This study evaluated the trace mineral availability of zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), and selenium (Se) in major feed ingredients, including corn, wheat, soybean meal (SBM), fish (FM). Additionally, we assessed bioavailability these minerals pigs supplemented with inorganic, organic, nano-sized forms prepared via hot-melt extrusion (HME). A total 64 barrows (Yorkshire × Landrace Duroc crossbreds) an average initial body weight 26.61 ± 4.12 kg were housed individually...

Abstract The Fischer–Tropsch synthesis (FTS) is a feasible pathway to chemicals and fuels from underutilized resources like coal, natural gas, biomass, shale instead of the current petroleum‐based production. Owing its high activity low price, iron‐based catalysts are widely used in FTS, yet with higher better selectivity should be developed for widespread applications. Herein, we report unique strategy synthesize an efficient iron catalyst FTS by applying graphitic carbon nitride (g‐C 3 N 4...

Curcuma longa L. (turmeric) is used as a food spice; however, its strong taste restricts wider applications ingredient despite well-known health benefits. To develop an effective yet simple process for enhancing antioxidant and anti-inflammatory activities, turmeric was gun-puffed at various pressures. Puffed exhibited increase in brown color porous structures, indicating the occurrence of Maillard reaction vaporization during process. Proximal analysis revealed that puffing did not alter...
