Regulation of the valleytronic properties in single-layer NbSeCl.

The regulation of the valleytronic properties of two-dimensional materials can contribute to the in-depth study of valley physics and improve its potential for applications in valleytronic devices. Herein, we systematically investigate the electronic properties and the modulation of the valleytronic properties in single-layer NbSeCl.

Theoretical Study of the Ternary Compound Monolayer CuPSe for Photocatalytic Water Splitting with Efficient Optical Absorption.

Utilizing photocatalytic method to produce hydrogen by splitting water is an efficient strategy to solve the hotspot issues of energy crisis and environmental pollution. Herein, we systematically investigate the corresponding properties of the reported Cu-bearing ternary compound monolayer CuPSe by using the first-principle calculations.

High Curie temperature ferromagnetic monolayer T-CrSH and valley physics of T-CrSH/WS heterostructure.

Two-dimensional magnetic materials are attracting widespread attention not only for their excellent applications in spintronic devices but also for their potential to regulate valley splitting, which is crucial for valleytronics. Herein, we design a monolayer Janus ferromagnetic semiconductor T-CrSH by using first-principles calculations. We reveal that monolayer T-CrSH has a magnetic moment of 3 per unit cell, which is primarily contributed by the 3d orbitals of the Cr atom.

Photocatalytic water splitting for hydrogen production with high efficiency monolayer InTe: a theoretical study.

Employing density functional theory (DFT) calculations, we explore the excellent performance of two-dimensional (2D) semiconductor InTe in photocatalytic water splitting at the theoretical level. The calculated results illustrate that 2D InTe is a direct band gap semiconductor with a moderate band gap value and an ultrahigh optical absorption coefficient in the visible light region. It was found that its conduction band edge is higher than the reduction potential of water (-4.

Quasi-One-Dimensional Structure and Possible Helical Antiferromagnetism of RbMnBi.

Quasi-one-dimensional materials exhibit not only unique crystal structure but also abundant physical properties such as charge density wave, Luttinger liquid, and superconductivity. Here we report the discovery, structure, and physical properties of a new manganese-based quasi-one-dimensional material RbMnBi, which crystallizes in a monoclinic space group 2/ (No. 12) with lattice parameters = 23.

Sequence analysis of α-(1, 2)-fucosyltransferase gene in nine Chinese individuals with Para-Bombay phenotype.

Background: To analyze the sequence of α-(1, 2)-fucosyltransferase gene (FUT1) in nine individuals with Para-Bombay phenotype.

Methods: Para-Bombay phenotype was defined according to the serologic characteristics and ABO genotypes. The full coding region of FUT1 was amplified, genotype and haplotype were analyzed by direct and TOPO cloning sequencing which was used to discriminate heterozygous mutations of FUT1.
