Numerical and experimental investigation of laser remelting in selective laser melting of 316L stainless steel

Selective laser melting (SLM) has a wide application potential as a near-net-shape manufacturing process, but with the increasing quality requirements of additive manufactured parts in various industries, high demands are placed on the manufacturing quality, density uniformity an...

Biomass-plastic Co-pyrolysis for sustainable biochar: Mechanisms, reactor technologies, and circular-carbon applications

The rapid accumulation of lignocellulosic biomass residues and plastic waste poses significant environmental challenges because conventional disposal methods, including landfilling and incineration, contribute to greenhouse gas emissions and inefficient resource use. Biochar prod...

Hypergraph-Augmented Reconstruction and Adaptive Metric Aggregation Network for Few-Shot Fine-Grained Image Classification

Few-shot fine-grained image classification aims to recognize unseen fine-grained categories from very few labeled examples. The task is difficult because visually similar classes may differ only in subtle details, while images from the same class can vary considerably. Useful evi...

Evidence-hierarchy audit of public DGA benchmarks for trustworthy AI-assisted transformer assessment

Dissolved gas analysis (DGA) is widely used for condition assessment of oil-immersed power transformers, but public-data artificial intelligence (AI) studies can overstate evidential reliability when labels are heterogeneous, samples overlap across benchmarks, or random splits ig...

Decoupling Flavor From Spoilage: A Microbial and Chemical Framework for Volatile Sulfur Compounds and Biogenic Amines in Washed‐Rind and Aged Cheeses

ABSTRACT Ripened washed‐rind and long‐ripened cheeses owe their prized sulfurous, savory character to intensive proteolysis and amino‐acid catabolism; the same activity, when poorly controlled, also generates sensory off‐flavors and toxic biogenic amines (BAs). Histamine and tyra...

Static and dynamic biomechanical responses of the lumbar spine under different loads: A finite element study

Lumbar spinal loads differ across various scenarios, including lumbar extension in the lateral recumbent position, seated/standing trunk extension, upright sitting or standing, muscular tension, muscular relaxation, and whole-body vibration. Nevertheless, systematic comparative s...

Lattice Boltzmann Modeling of Droplet Impact on a Superhydrophobic Ridge

ABSTRACT The impact dynamics of droplets on a single rectangular superhydrophobic ridge are systematically investigated using the lattice Boltzmann method. The effects of ridge width, droplet deviation, and Weber number on droplet deformation and breakup are examined through exte...

Influence of glaze-iced insulators on force and motion characteristics of charged water droplets under DC voltage and natural icing test validation

Glaze ice exhibits high density and strong adhesion, readily forming ice bridges that impair insulator performance. While previous studies have primarily concentrated on macroscopic icing behavior under AC or DC fields, the role of icicles in affecting the motion of charged water...

Cutting performance and surface integrity of hardened GCr15 bearing steel in laser-ultrasonic vibration-assisted turning

Hardened GCr15 bearing steel is an important engineering material for bearing applications, where high dimensional accuracy and surface integrity are required. Nevertheless, the high hardness of the material makes efficient machining difficult and often leads to accelerated tool...

Multi-omics analyses identify PGAM2-associated energy-metabolism signatures linked to bull testis size divergence and spermatogenic potential

Testicular development and spermatogenic capacity are important determinants of male reproductive potential and breeding value in livestock. However, the molecular features associated with natural variation in testicular size remain incompletely understood. In this study, large-t...

Transition Mechanism of Promotion/Inhibition of Ice Accretion on Overhead Ground Wires Under Electric Field Effects

Ice accretion on overhead ground wires is a significant hazard threatening the safe operation of power systems. The electric field exerts a complex bidirectional effect—both promoting and inhibiting—on ice growth, and the underlying mechanism of this transition remains unclear. T...

Separation of Methanol and MTBE Azeotrope via Choline-Based Deep Eutectic Solvents: Liquid–Liquid Equilibrium and Molecular Mechanism

Abstract Methyl tert-butyl ether (MTBE) is an excellent additive for gasoline. Because of the formation of an azeotropic mixture by MTBE and methanol during its production, it is a challenge to separate the azeotrope. To investigate the effect of hydrogen bond donor (HBD) functio...

Pb(II) Selectivity of Oxygen-Functionalized Lignite-Based Carbon Material in the Presence of Competitive Cu(II)/Cd(II) Interference

Abstract A series of lignite-derived activated carbons (CK-400-CK-700) was prepared by KOH activation to clarify the effects of pore structure and surface oxygen functionality on Pb(II) adsorption. Although the BET surface area increased from 456.60 to 1300.70 m2·g–1 with activat...

Lattice-Confined Rh Single Atoms in SrTiO3 Enable Leaching-Resistant and Durable Heterogeneous Hydroformylation

Abstract Heterogeneous Rh catalysts hold great promise for olefin hydroformylation by integrating the catalytic efficiency of Rh with facile separation and recycling. However, achieving high catalytic activity together with long-term stability remains a formidable challenge becau...
