Effective Measurement of the Influence of an Ovoidal Particle Shape on the Tortuosity and Permeability: Theoretical and Numerical Studies

An ovoid is a common particle, which is usually formed by constant extrusion and friction during running water handling. However, there is still debate over how the form of ovoidal particles affects the tortuosity and water permeability of particle packing systems. The tortuosity...

Disclosing Structural Determinants Governing Stereopreferences of Ketoreductases toward Reduction of Halogenated Aryl Ketones

Abstract Ketoreductases (KREDs) are widely used for asymmetric ketone reduction, yet predictable control of stereoselectivity remains challenging due to the limited understanding of structure–selectivity relationships. Here, we integrate site-directed mutagenesis and molecular dy...

Unveiling the determinants and formation mechanisms of the intention-behavior gap among private enterprises participating in new infrastructure construction

Purpose A disconnect between the intention to participate and the actual engagement among private enterprises is impeding the effective promotion of new infrastructure construction (NIC). To address this critical barrier, this study aims to identify the determinants of this inten...

Amino‐Modified Dual Support for Synergistic Stabilization of Ultrafine NiPd Nanoparticles as a Superior Dehydrogenation Catalyst

ABSTRACT The development of low‐cost and highly active heterogeneous catalysts is crucial for promoting formic acid (FA) as a practical hydrogen carrier for fuel cells. Herein, we report a novel strategy for the synthesis of ultrafine NiPd bimetallic nanoparticles (NPs) supported...

Promotion of nisin production by integrating rare earth salt stimulation and foam separation with fermentation system

Nisin is an antimicrobial peptide which offers potential for the replacement of synthetic preservatives in the food industry. However, nisin is difficult to produce on a large scale due to low synthesis efficiency and severe feedback inhibition. The objective of this work was to...

Prediction Method of Residual Electrical Life of Air Circuit Breakers Based on Mechanical Parameters

Air circuit breakers are critical protective devices in low-voltage distribution systems, and their reliability is considered to have significant influence on the operation of such systems. With respect to the electrical performance degradation of air circuit breakers, the relati...

Systematic ConditionsOptimization of Kilometer-ScaleAramid Fiber with High Tensile Strength via Microfluidic Spinning

Abstract Poly(p-phenylene benzimidazole-benzamide) (PBIA) fiber, with superior mechanical properties, has become a promising chemically synthesized high-performance aramid fiber. The crystallization and orientation behaviors of PBIA fiber critically determine its comprehensive pr...

Spatial Heterogeneity and Influencing Factors of the Resilient Cultural Landscape of Great Wall Villages: A Case Study of Chicheng County, China

Great Wall villages are living cultural landscapes within a linear heritage corridor, yet they face growing pressures from population decline, rural hollowing, uneven development, and tourism-related transformation. This study evaluates the cultural landscape resilience of 20 Gre...

Regulating Solvation Chemistry via Strongly Coordinating Anion and Weakly Solvating Cosolvent for Low‐Temperature Sodium Metal Batteries

ABSTRACT Sodium metal batteries (SMBs) hold great promise for next‐generation energy storage systems due to their abundant sodium resources, high theoretical specific capacity, and low redox potential. However, they suffer from rapid capacity degradation at low operating temperat...
