Non-metallic surface-modified X-Cu (X = F, Cl, Br) metal catalysts for all-pH hydrogen evolution reaction with high performance.

Producing hydrogen through water electrolysis represents a clean and sustainable solution that is crucial in addressing the energy crisis. Nonetheless, the slow process of water electrolysis leads to large different kinetics for hydrogen evolution reaction (HER) under different pH solutions. Here, we designed surface modified metallic X-Cu catalysts (X = F, Cl, Br) with different non-metallic elements on nickel foam (NF) using an electrochemical deposition method, which realizes high performance for all-pH range.

Monolayer MXO as potential 2D altermagnets and half-metals: a first principles study.

Realizing novel two-dimensional (2D) magnetic states would accelerate the development of advanced spintronic devices and the understandings of 2D magnetic physics.

Humoral and cellular immune responses induced by serogroup W135 meningococcal conjugate and polysaccharide vaccines.

Investigating the mechanisms by which W135 meningococcal conjugate (PSW135-TT) activates adaptive immune responses in mice can provide a comprehensive understanding of the immune mechanisms of bacterial polysaccharide conjugate vaccines. We compared B-cell and T-cell immune responses immunized with W135 meningococcal capsular polysaccharides (PSW135), tetanus toxoid (TT) and PSW135-TT in mice. The results showed that PSW135-TT could induce higher PSW135-specific and TT-specific IgG antibodies with a significant enhancement after two doses.

Electronic structures and quantum capacitance of twisted bilayer graphene with defects based on three-band tight-binding model.

Twisted bilayer graphene (tBLG) with C vacancies would greatly improve the density of states (DOS) around the Fermi level () and quantum capacitance; however, the single-band tight-binding model only considering p orbitals cannot accurately capture the low-energy physics of tBLG with C vacancies. In this work, a three-band tight-binding model containing three p orbitals of C atoms is proposed to explore the modulation mechanism of C vacancies on the DOS and quantum capacitance of tBLG. We first obtain the hopping integral parameters of the three-band tight-binding model, and then explore the electronic structures and the quantum capacitance of tBLG at a twisting angle of = 1.

Ferromagnetic ordering correlated strong metal-oxygen hybridization for superior oxygen reduction reaction activity.

The efficiency of transition-metal oxide materials toward oxygen-related electrochemical reactions is classically controlled by metal-oxygen hybridization. Recently, the unique magnetic exchange interactions in transition-metal oxides are proposed to facilitate charge transfer and reduce activation barrier in electrochemical reactions. Such spin/magnetism-related effects offer a new and rich playground to engineer oxide electrocatalysts, but their connection with the classical metal-oxygen hybridization theory remains an open question.

Organic Photocathode Supported by Copper Nanosheets Array for Overall Water Splitting.

The Z-scheme overall solar water splitting is a mimic of natural photosynthesis to convert solar energy into chemical energy. Since the energy levels of most organic semiconductors match well with the hydrogen evolution potential, they have great application prospects as photocathodes in Z-scheme photoelectrochemical systems. However, due to the weak light absorption and difficult carrier separation, the photocurrent density and onset potential of organic photocathodes are still low.

In late 2019, COVID-19 quickly spread across the globe and became a pandemic crisis. This study aimed to investigate whether the establishment of the PGY training had positive effects on the self-efficacy and emotional traits of medical workers.

Electronic structures and anisotropic carrier mobilities of monolayer ternary metal iodides MLaI(M=Mg, Ca, Sr, Ba).

Exploiting two-dimensional (2D) materials with natural band gaps and anisotropic quasi-one-dimensional (quasi-1D) carrier transport character is essential in high-performance nanoscale transistors and photodetectors. Herein, the stabilities, electronic structures and carrier mobilities of 2D monolayer ternary metal iodides MLaI(M = Mg, Ca, Sr, Ba) have been explored by utilizing first-principles calculations combined with numerical calculations. It is found that exfoliating MLaImonolayers are feasible owing to low cleavage energy of 0.

Phage therapy is an alternative approach to overcome the problem of multidrug-resistant bacteria. Here, a novel bacteriophage AhyVDH1, which infects Aeromonas hydrophila 4572, was isolated and its morphology, one-step growth curve, lytic activity, stability under various conditions, and genome were investigated. Transmission electron microscopy revealed that AhyVDH1 has an icosahedral head 49 nm in diameter and a contractile tail 127 nm in length, suggesting that it belongs to the family Myoviridae.

Ideal two-dimensional solid electrolytes for fast ion transport: metal trihalides MX with intrinsic atomic pores.

Exploring ultrathin two-dimensional (2D) solid electrolytes with fast ion transport is highly desirable in nanoelectronics, ionic devices and various energy storage systems, following the rapid scaling of devices to the nanometer scale. Herein, two-dimensional (2D) metal trihalides MX3 (ScCl3, ScBr3, AsI3, ScI3, YBr3, SbI3, YI3 and BiI3) with intrinsic atomic pore structures have been examined and found to be promising as realistic 2D solid electrolytes. Through examining the binding interactions and the diffusion barriers of monolayer MX3-ion (Li+, Na+, K+, Mg2+, and Ca2+) systems by utilizing first principles calculations, it is found that MX3-ion complexes are energetically favorable and the energy barriers of some MX3-ion systems are comparable to or even smaller than those of the conventional solid electrolyte systems.

NLRC5 mediates cell proliferation, migration, and invasion by regulating the Wnt/β-catenin signalling pathway in clear cell renal cell carcinoma.

NLRC5, a newly discovered member of the NLR family, has been reported to regulate immune responses and promote cell proliferation, migration, and invasion in hepatocellular carcinoma. However, to date, the potential regulatory roles and molecular mechanisms by which NLRC5 affects the development and progression of clear cell renal cell carcinoma (ccRCC) remain largely unknown. In this study, human clinical data from The Cancer Genome Atlas database revealed that increased NLRC5 expression was associated with advanced stage and poor prognosis in ccRCC patients.

Simulation of Stress Field during the Selective Laser Melting Process of the Nickel-Based Superalloy, GH4169.

In this paper, GH4169 alloy's distributions of temperature and stress during the selective laser melting (SLM) process were studied. The SLM process is a dynamic process of rapid melting and solidification, and we found there were larger temperature gradients near the turning of scan direction and at the overlap of the scanning line, which produced thermal strain and stress concentration and gave rise to warping deformations. The stresses increased as the distance became further away from the melt pool.
