Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Experimental Study on the Combustion and Explosion Characteristics of Tributyl Phosphate and Kerosene Mixtures at Different Initial Pressures in High‐Temperature Environments

Energy Science &Engineering, EarlyView.
The explosion hazard of TBP and kerosene mixed vapor in the nuclear fuel reprocessing process is studied. The results enrich the explosion characteristics and explosion limits of TBP‐kerosene, and provide reference value and basis for the safety setting of the operation process and operating environment of nuclear fuel reprocessing plants ABSTRACT As ...

Enhancement Method and Safety Analysis of Sealing Unit in Gas Packer

Shiyou jixie
The gas packer rubber is a key part for achieving separate layer and interval production of gas wells. The conventional three-unit rubber barrel structure is prone to initial failure during setting, which will lead to a decrease in the overall stress ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...
