Strain-Reduced Inversion Symmetry in Ultrathin SnPSe Crystals for Giant Bulk Piezophotovoltaic Generation.

With the potential to surpass the Shockley-Queisser (S-Q) limitation for solar energy conversion, the bulk photovoltaic (BPV) effect, which is induced by the broken inversion symmetry of the lattice, presents prospects for future light-harvesting technologies. However, the development of BPV is largely limited by the low solar spectrum conversion efficiency of existing noncentrosymmetric materials with wide band gaps. This study reports that the strain-induced reduction of inversion symmetry can enhance the second-order nonlinear susceptibility (χ) of SnPSe crystals by an order of magnitude, which contributes to an extremely high value of 1.

Achieving stable partial nitrification by exploiting lag phase of NOB recovery for selective washout.

Stable inhibition of nitrite-oxidizing bacteria (NOB) is a significant challenge in achieving partial nitrification (PN) and partial nitrification-anaerobic ammonia oxidation (PNA). Growing evidence suggested that NOB can develop resistance to suppression over time, leading to the re-enrichment of NOB within reactors. To address these issues, this study aimed to achieve stable PN by regulating SRT to selectively washout NOB during the lag phase of activity recovery following FA/FNA exposure.

Differential insights into the distribution characteristics of bacterial communities and their response to typical pollutants in the sediment and soil of large drinking water reservoir.

In this study, a large drinking water reservoir (Fengshuba Reservoir) was chosen as a representative case, and the bacterial communities in the sediments and soils of Water-level fluctuating zone (WLFZ) as well as their responses to heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) were systematically investigated. The results indicated that the abundance and diversity of the bacterial community obviously changed with seasonal hydrological variations in sediments, and the absolute abundance and composition of bacteria community differed significantly between the sediment phase and soil phase. Bacteria with the ability to degrade pollutants rapidly proliferate and gain ascendancy in the soil phase, with Burkholderia-Caballeronia-Paraburkholderia (B-C-P) and Bradyrhizobium forming the core of the largest community.

Measuring Attractive Interaction between a Self-Electrophoretic Micromotor and a Wall.

Chemically driven micromotors exhibit a pronounced affinity for nearby surfaces, yet the quantification of this motor-wall interaction strength remains unexplored in experiments. Here, we apply an external force to a self-electrophoretic micromotor which slides along a wall and measures the force necessary to disengage the motor from the wall. Our experiments unveil that the required disengaging force increases with the strength of chemical driving, often surpassing both the motor's effective gravity and its propulsive thrust.

Phase evolutions of sodium layered oxide cathodes during thermal fluctuations.

Layered transition metal oxide (NaTMO) cathodes are considered highly appropriate for the practical applications of sodium-ion batteries (SIBs) owing to their facile synthesis and high theoretical capacity. Generally, the phase evolution behaviors of NaTMO during solid-state reactions at high temperature closely related to their carbon footprint, prime cost, and the eventual electrochemical properties, while the thermal stability in various desodiated states associated with wide temperature fluctuations are extremely prominent to the electrochemical properties and safety of SIB devices. Therefore, in this review, the influences of sintering conditions such as pyrolysis temperature, soaking time, and cooling rates on the phase formation patterns of NaTMO are summarized.

Synergistic interface regulation for achieving fast kinetics and highly reversible zinc metal anodes.

Uncontrolled zinc dendrite growth and adverse side reactions at the Zn anode interface severely limit its practical application. Based on theoretical calculations, this study in situ constructs a functional interface (ICFI Zn) on the Zn anode surface, consisting of a surface-textured structure and a zinc-philic protective layer. Benefiting from the synergistic effect of ion regulation and atomic anchoring of this functional interface, the ICFI Zn anode achieves homogenised regulation of ion fluxes, facilitates ion transport kinetics, effectively suppresses side reactions and guides the deposition of dendrite-free Zn.

Nanofiltration membranes with fast water transport induced by controlled interfacial diffusion to enhance desalination and micropollutant removal.

Nanofiltration (NF) membranes offer tremendous potential in wastewater reuse, desalination, and resource recovery to alleviate water scarcity and environmental contamination.

In situ HO production from self-sufficient heterogeneous Fenton reaction over Fe/MoS for potential environmental remediation applications.

Fenton reaction technology has worked well in water and wastewater treatment; however it is often limited by such problems as continuous external supply of HO, slow Fe/Fe cycle rate, high energy requirements, and maintenance of low pH during operation.
