Freeze–Thaw Durability and Pb Leaching Control of Graphene-Assisted MICP-Stabilized Pb-Contaminated Loess: Coupled Hydro-Environmental and Geotechnical Performance

Freeze–thaw cycling can strongly disturb the pore-water environment, soil fabric, and contaminant mobility of heavy-metal-contaminated loess, thereby threatening the long-term effectiveness of stabilization treatments in seasonally frozen regions. This study investigated the coup...

Seismic fragility analysis of multi-line transmission structure based on gas-insulated switchgear (GIS) equipment for nuclear power applications

The stable transmission of nuclear-generated electricity is vital for grid reliability and reactor external power supply. This study addresses this critical need by developing Finite Element Models (FEMs) of Gas-Insulated Switchgear (GIS) and a representative multi-line transmiss...

Influence of Composite Mineral Admixtures and Expansive Agent on the Mechanical Properties, Durability and Microstructure of Cementitious Materials

To improve volume stability and durability of cementitious materials, a composite mineral admixture including ground granulated blast furnace slag, fly ash and silica fume was incorporated at a fixed 12% replacement ratio together with varying dosages of an expansive agent (EA)....

Reactive PLD Guides the Transformation to Noncrystalline C‐Ga‐Se‐Cl Films with a Halogen‐Defined Interface for Enhanced Luminescence

ABSTRACT Pulsed laser deposition is known for copying the composition of a target into a thin film. Adding a reactive gas can change the growth process, but the chemistry usually stays close to the target. Using a carbon‑rich environment and a pulsed chlorine source from polyviny...

Risk-Informed Ecological Network Optimization in a Semi-Arid Coal Mining Landscape

Coal mining landscapes require restoration strategies that account not only for where ecological risk is concentrated but also for how risk constrains landscape connectivity. However, landscape ecological risk assessment is still commonly used as a zoning tool, with weak links to...

Risk Assessment of Post-Earthquake Gas Explosion Disaster Chains in High-Rise Residential Buildings: A Fuzzy Bayesian and Complex Network Approach

To address the challenges in risk prevention and control of post-earthquake gas explosions in high-rise buildings and the deficiencies of traditional methods in handling uncertainty, this paper conducts a risk evolution analysis from the perspectives of fuzzy Bayesian networks (F...

Silica-Inspired Aerogel Thermal Metamaterials with Gradient Porosity: High-Temperature-Induced Pore Sintering Evolution via Nanoindentation

Localized densification of nanoporous silica under combined mechanical compression and elevated temperature involves coupled pore collapse, skeletal rearrangement, and thermally activated sintering. Clarifying how local pre-compression regulates these processes is important for u...
