Development of High-Performance Ethanol Gas Sensors Based on LaO Nanoparticles-Embedded Porous SnO Nanofibers.

Porous pure SnO nanofibers (NFs) and LaO nanoparticles (NPs)-embedded porous SnO NFs were successfully synthesized via electrospinning followed by calcination. These materials were systematically evaluated as gas-sensing elements in metal-oxide-semiconductor (MOS) sensors. The LaO NPs embedded in porous SnO NFs demonstrated superior gas-sensing performance compared to pure SnO NFs.

Can energy aid drive greener economic growth? A global evidence.

As a bilateral or multilateral international policy, foreign aid has the potential to contribute to economic growth in recipient countries, but the impact on green growth, especially aid flows to the energy sector, is unclear. Existing studies have paid little attention to the actual effects of whether energy aid is effective in raising green total factor productivity (GTFP) in recipient countries. To fill this gap, this study investigates the dynamic impact of energy aid on GTFP in recipient countries using balanced panel data for 92 countries from 2002 to 2019, and the study also examines potential sectoral heterogeneity and impact mechanisms.

Enhanced Energy Storage Performance through Controlled Composition and Synthesis of 3D Mixed Metal-Oxide Microspheres.

Binary transition metal oxide complexes (BTMOCs) in three-dimensional (3D) layered structures show great promise as electrodes for supercapacitors (SCs) due to their diverse oxidation states, which contribute to high specific capacitance. However, the synthesis of BTMOCs with 3D structures remains challenging yet crucial for their application. In this study, we present a novel approach utilizing a single-step hydrothermal technique to fabricate flower-shaped microspheres composed of a NiCo-based complex.

Effects of Gas Composition on the Lipid Oxidation and Fatty Acid Concentration of Tilapia Fillets Treated with In-Package Atmospheric Cold Plasma.

Cold plasma (CP) is a non-thermal preservation technology that has been successfully used to decontaminate and extend the shelf life of aquatic products. However, the preservation effect of CP treatment is determined by several factors, including voltage, time, and gas compositions. Therefore, this study aimed to investigate the effects of gas composition (GasA: 10% O, 50% N, 40% CO; GasB: air; GasC: 30% O, 30% N, 40% CO) on the lipid oxidation of tilapia fillets treated after CP treatment.

A perspective on the molecular simulation of DNA from structural and functional aspects.

As genetic material, DNA not only carries genetic information by sequence, but also affects biological functions ranging from base modification to replication, transcription and gene regulation through its structural and dynamic properties and variations. The motion and structural properties of DNA involved in related biological processes are also multi-scale, ranging from single base flipping to local DNA deformation, TF binding, G-quadruplex and i-motif formation, TAD establishment, compartmentalization and even chromosome territory formation, just to name a few. The sequence-dependent physical properties of DNA play vital role in all these events, and thus it is interesting to examine how simple sequence information affects DNA and the formation of the chromatin structure in these different hierarchical orders.

Hierarchical dinucleotide distribution in genome along evolution and its effect on chromatin packing.

Dinucleotide densities and their distribution patterns vary significantly among species. Previous studies revealed that CpG is susceptible to methylation, enriched at topologically associating domain boundaries and its distribution along the genome correlates with chromatin compartmentalization. However, the multi-scale organizations of CpG in the linear genome, their role in chromatin organization, and how they change along the evolution are only partially understood.

Effective Electrocatalytic Hydrogen Evolution in Neutral Medium Based on 2D MoP/MoS Heterostructure Nanosheets.

The hydrogen evolution reaction (HER) in the neutral medium can avoid the problems caused by strong acid (bases) media and thus is promising for practical application. The suitable catalyst in the neutral medium for HER requires good conductivity for decreasing ohm resistance, porous structures for weakening diffusion resistance, and plentiful active sites, but its synthesis remains a challenge. Here, the 2D MoP/MoS heterostructure nanosheets rather than common anion doping supported on carbon cloth (CC) was designed to meet the above criteria.

Anion-Modulated HER and OER Activities of 3D Ni-V-Based Interstitial Compound Heterojunctions for High-Efficiency and Stable Overall Water Splitting.

Overall water splitting driven by a low voltage is crucial for practical H evolution, but it is challenging. Herein, anion-modulation of 3D Ni-V-based transition metal interstitial compound (TMIC) heterojunctions supported on nickel foam (Ni N-VN/NF and Ni P-VP /NF) as coupled hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalysts for efficient overall water splitting is demonstrated. The heterointerface in Ni N-VN has a suitable H* absorption energy, being favorable for enhancing HER activity with onset overpotential (η ) of zero and Tafel slope of 37 mV dec in 1 m KOH (close to that of Pt/C/NF).
