Understanding the microforming related tribological science of engineered magnesium alloys at high temperatures

Friction
Microforming is a promising approach to micromanufacturing miniaturized components. The material flow and tribological aspects of microforming are affected by the size effect.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. Materials and Methods Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each group).

Organic–Inorganic Composite Nanofibers Based on YSZ Nanofibers Anchored PANI/SnS2 Heterojunction for Flexible Room Temperature NO2 Sensor

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
A novel organic–inorganic YSZ@PANI/SnS2 composite nanofiber film was prepared via an in‐situ construction strategy of a PANI interfacial layer. The biomimetic "branch‐leaf" structure effectively disperses and releases stress and energy, while accelerating gas diffusion/transport and providing abundant active sites.

Continuum nanomechanics for nanocrystalline and ultrafine grain materials

IOP Conference Series: Materials Science and Engineering, 2014
An extension of the classical continuum mechanics model is provided for the solution of boundary value problems at the nanoscale. The resulting continuum nano-mechanical model is based on the introduction of new terms to account for the interaction of bulk and surface points of the medium, which becomes significant as the specimen size is reduced down ...

Prediction of the Stress-Strain Response of the Ultrafine-Grained Materials Using Multi-Scale Analysis

, 2010
There are several severe plastic deformation processes that transform the material from microsized grains to the nanosized grains under large deformations. The grain size of a macrostructure is generally 300 μm.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like
