Both theoretical and experimental studies have confirmed that combining two or more two-dimensional (2D) monolayer materials into heterostructures is an efficient way to tailor the physical properties of single 2D materials. In this paper, we design a 2D bilayer α-tellurene/GaTe (Te/GaTe) van der Waals heterostructure (vdWH) with an extremely strong interlayer hybridization, a distinctive electronic, spin and optical properties using first-principles calculations. Our calculated results show that the Te/GaTe vdWH is an intrinsic type-I vdWH with an indirect band gap of 0.

Type II diabetes mellitus (T2DM) is a prevalent, long-standing metabolic condition marked by the body's reduced response to insulin and inadequate insulin production, impacting a significant portion of the global population. Research has demonstrated that bioactive peptides play a crucial role in reducing blood sugar levels, enhancing insulin sensitivity, balancing lipid metabolism, and combating inflammation. These peptides also contribute to the enhancement of pancreatic islet function, lowering systemic inflammation by influencing various molecular signaling pathways.

This study aimed to identify novel α-amylase inhibitory peptides from Russian sea cucumbers and elucidate their inhibitory mechanisms. Among the 52 identified sea cucumber peptide (SCP), two peptides with potential α-amylase inhibitory activity, FPSPPLVA (SCP1) and GPPMPPPPLP (SCP2), were selected from the sequences researched. The results showed that both SCP1 and SCP2 exhibited α-amylase inhibitory activity with IC of 0.

Pyrethroids are widely used against agricultural pests and human disease vectors due to their broad insecticidal spectrum, fast action, and low mammalian toxicity. Unfortunately, overuse of pyrethroids has led to knockdown resistance (kdr) caused by mutations in voltage-gated sodium channels. Mutation I1011M was repeatedly detected in numerous pyrethroid-resistant Aedes aegypti populations from Latin American and Brazil.

The low hardness and poor wear resistance of laser-cladding 316L stainless steel impose significant constraints on its practical applications. In this study, a strategy for strengthening laser-cladding 316L stainless steel with WMoTaNb refractory high-entropy alloy as a reinforcement material is proposed. The results confirm that the coating primarily comprises a body-centered cubic (BCC) Fe-based solid solution, a network-distributed hexagonal FeX (X = W, Mo, Ta, and Nb) Laves phase, and a diffusely distributed face-centered cubic (FCC) (Ta, Nb)C phase.

Hydrogenation of carbon dioxide to value-added chemicals and fuels has recently gained increasing attention as a promising route for utilizing carbon dioxide to achieve a sustainable society. In this study, we investigated the hydrogenation of CO over M/SiO and M/AlO (M = Co, Ni) catalysts in a dielectric barrier discharge system at different temperatures. We compared three different reaction modes: plasma alone, thermal catalysis, and plasma catalysis.

LaCaCoFeO in its various compositions has proven to be an excellent CO-resistant oxygen transport membrane that can be used in plasma-assisted CO conversion. With the goal of incorporating green hydrogen into the CO conversion process, this work takes a step further by investigating the compatibility of LaCaCoFeO membranes with hydrogen fed into the plasma. This will enable plasma-assisted conversion of the carbon monoxide produced in the CO reduction process into green fuels, like methanol.

Due to the asymmetrical structure in the vertical direction, Janus two-dimensional (2D) monolayer (ML) materials possess some unique physical properties, holding great promise for nanoscale devices. In this paper, based on the newly discovered MoAZ (A = Si, Ge; Z = N, P, As) ML, we propose a class of 2D Janus MoAZH ML materials with good stability and excellent mechanical properties using first-principles calculations. We demonstrate that the novel Janus MoAZH ML materials are all semiconductors with bandgaps ranging from 0.

Rice ratooning, the fast outgrowth of dormant buds on stubble, is an important cropping practice in rice production. However, the low ratooning ability (RA) of most rice varieties restricts the application of this cost-efficient system, and the genetic basis of RA remains unknown. In this study, we dissected the genetic architecture of RA by a genome-wide association study in a natural rice population.

Two-dimensional ferroelectric monolayer materials with reversible spontaneous polarization provide more regulatory dimensions for their relevant van der Waals heterostructures. Using first-principles calculations, we construct the CN/InSe bilayer heterostructure and study its physical properties as well as the effects of -field and strain. The results indicate that the intrinsic polarization of the component InSe monoalyer can significantly adjust the electronic properties of the CN/InSe heterobilayer.

Topologically disordered metallic glass nanoparticles (MGNPs) with highly active and tailorable surface chemistries have immense potential for functional uses. The synthesis of free-standing MGNPs is crucial and intensively pursued because their activity strongly depends on their exposed surfaces. Herein, a novel laser-evaporated inert-gas condensation method is designed and successfully developed for synthesizing free-standing MGNPs without substrates or capping agents, which is implemented via pulse laser-induced atomic vapor deposition under an inert helium atmosphere.
