Aqueous rechargeable Zn-metal batteries (ARZBs) are considered one of the most promising candidates for grid-scale energy storage. However, their widespread commercial application is largely plagued by three major challenges: The uncontrollable Zn dendrites, notorious parasitic side reactions, and sluggish
In this paper, the Ir-modified MoS2 monolayer is suggested as a novel gas sensor alternative for detecting characteristic decomposition products of SF6, including H2S, SO2, and SOF2. The corresponding adsorption properties sensing behaviors were systematically studied using density functional theory (DFT) method. theoretical calculation indicates that Ir modification can enhance surface activity improve conductivity intrinsic MoS2. physical structure formation, states (DOS), deformation...
Abstract. Colloidal particles are the most active soil components, and they vary in elemental composition environmental behaviors with particle size due to heterogeneous nature of natural soils. The purposes present study clarify how affects physicochemical properties aggregation kinetics colloids further reveal underlying mechanisms. Soil colloidal fractions, from two alkaline soils – Anthrosol Calcisol were subdivided into three ranges: d<2 µm, d<1 µm d<100 nm. organic inorganic...
Soil structural stability is fundamentally linked to soil functionality and sustainable productivity. Rheological properties describe the deformation flow behavior of under external stress, playing a crucial role in understanding structure stability. Despite their importance, studies about rheological black soils Northeast China remain limited. This study aims assess two kinds with different degrees degradation China. The parameters these various water contents shearing were quantified by...
The electric field distribution along the insulator surface plays a significant role in improving flashover characteristics of insulation an HVdc power system. Functionally graded material with conductivity ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\sigma $ </tex-math></inline-formula> -FGM) is promising approach that enables to be more uniform, which leads hinder flashover. This article proposes...
In this paper, we propose an analog circuit building block generator, which is composed of a layout-aware sizing scheme and automated layout generator. We reformulate the problem as novel constrained multi-objective optimization Bayesian that can find multiple different qualified designs. further leverage nested multi-fidelity method in to counterbalance schematic-level simulation expensive post-layout without losing efficiency. The generator enables in-loop generation, thus it possible set...
This work presents a highly secure anticounterfeiting strategy based on upconversion/afterglow hybrids with tricolor emissions tuned by single 975 nm laser. The are composed of NaYF4:Yb/Tm and NaYF4:Yb/Er microrods CaS:Eu2+ afterglow phosphors. Under excitation, the exhibit multicolor from green to white adjusting laser power then emit red light when is off. synergistic excitation blue-green emitted Tm/Er microrods, emission not only has strong initial intensity but also lasts for 3 s....
The effect of ion beam treatment on surface flashover characteristics epoxy is evaluated and explored. Epoxy samples are prepared carried out for 10-, 15-, 20-, 25-, 30-min durations using an end-Hall source. Flashover test both pristine treated conducted at negative dc voltage in air. results indicate the effectiveness to enhance properties epoxy. resin increased 21.35% after a duration 20 min. Optical microscopic images, scanning electron microscopy (SEM) from Fourier transform infrared...
Insulating oil is indispensable cooling impregnation and isolation agent for oil-filled electrical equipment, such as power transformers. The aging byproducts, i.e., water organic acids, impose a serious threat to these expensive reclamation complicated process.

To mitigate the issues of soil quality degradation and environmental pollution caused by excessive fertilizer use in apple orchards, present study investigated effects organic substitution combined with chemical nitrogen (N) reduction on nutrient status, enzyme activity, microbial communities (bacteria, fungi archaea) over one year an orchard. Five fertilization treatments were implemented, including 100% (CK), 80% + 20% liquid humic (S1), 60% 40% (S2), (S3), (S4). Substituting fertilizers...
Tailoring the secondary surface morphology of electro-spun nanofibers has been highly desired, as such delicate structures equip with distinct functions. Here, we report a simple strategy to directly reconstruct polyvinyl alcohol/polyvinylpyrrolidone (PVA/PVP) by water evaporation. The roughness and diameter depend on temperature during vacuum drying. Surface changes from smooth rough were observed at 55 °C, significant drop in nanofiber diameter. We attribute formation intermolecular forces...
