Epitaxial Growth of GaN Films on Chemical-Vapor-Deposited 2D MoS Layers by Plasma-Assisted Molecular Beam Epitaxy.

The van der Waals epitaxy of wafer-scale GaN on 2D MoS and the integration of GaN/MoS heterostructures were investigated in this report. GaN films have been successfully grown on 2D MoS layers using three different Ga fluxes via a plasma-assisted molecular beam epitaxy (PA-MBE) system. The substrate for the growth was a few-layer 2D MoS deposited on sapphire using chemical vapor deposition (CVD).

Droplet epitaxy of InGaN quantum dots on Si (111) by plasma-assisted molecular beam epitaxy.

The droplet epitaxy of indium gallium nitride quantum dots (InGaN QDs), the formation of In-Ga alloy droplets in ultra-high vacuum and then surface nitridation by plasma treatment, is firstly investigated by using plasma-assisted molecular beam epitaxy. During the droplet epitaxy process, in-situ reflection high energy electron diffraction patterns performs the amorphous In-Ga alloy droplets transform to polycrystalline InGaN QDs, which are also confirmed by the characterizations of transmission electron microscopy and X-ray photoelectron spectroscopy. The substrate temperature, In-Ga droplet deposition time, and duration of nitridation are set as parameters to study the growth mechanism of InGaN QDs on Si.

The practical process of manufacturing poly(methyl methacrylate)-based scaffolds having high porosity and high strength.

Poly(methyl methacrylate) (PMMA)-based scaffolds have been produced using the granule casting method with grain sizes M80-100 and M100-140. The novelty of this study was the application of the cold-cutting method (CCm) to reduce the PMMA granule size. PMMA granule shape, granule size (mesh), and sintering temperature were the primary variables in manufacturing PMMA scaffolds.

Modification of dietary rumen degradable starch content by chemical processing of feed ingredients: A meta-analysis.

The efficiency of starch utilization in ruminant feed can be enhanced by reducing the degradation of starch in the rumen. Chemical processing of feed ingredients may modify such ruminal starch degradation. This study aimed to evaluate the chemical processing of ruminant feed ingredients on rumen degradable starch (RDS) and starch degradation kinetics in the rumen.

Evaluation of Megasphaera elsdenii supplementation on rumen fermentation, production performance, carcass traits and health of ruminants: a meta-analysis.

Objective: This study was conducted to evaluate the use of Megasphaera elsdenii (M. elsdenii) as a probiotic on rumen fermentation, production performance, carcass traits and health of ruminants by integrating data from various related studies using meta-analysis.

Methods: A total of 32 studies (consisted of 136 data points) were obtained and integrated into a database.
