Dual‐Plane Engineered GO‐Shielded GaN Core–Shell Nanowires for Cl−‐Resilient and Durable Seawater Splitting Photoelectrodes

Carbon Energy, EarlyView.
The double‐bond phenomenon enables dual energy band mechanisms that enhance the efficiency of seawater splitting. Atomic interactions at the GO/GaN interface encompass various configurations, such as van der Waals interactions, covalent interactions, type‐II and Z‐scheme alignments, and chloride‐ion repulsion.

Influence of Contact Pressure on Performance and Crossover in Zero‐Gap Alkaline Water Electrolysis

Chemie Ingenieur Technik, EarlyView.
Cell performance and product gas quality in zero‐gap alkaline water electrolysis are influenced by the mechanical contact pressure in the electrode area. With a newly developed contact‐pressure cell, it was found that the influence of contact pressure can vary drastically, depending on the cell configuration, electrode type, and diaphragm.

Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

Deep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Steel segment–anchor bolt (cable) structure for TBM tunnels under extremely intense rockburst conditions: Design method and field application

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.

Prediction of numerical distortion after welding with various welding sequences and clampings

Metalurgija, 2010
Welding simulation of a test cover for hydropower plant was made due to very large dimensions of the cover. The main aim was to predict distortion after welding in order to avoid machining the cover. Welding process was simulated with the Sysweld program

Multifunctional Oleylamine Enables Direct Regeneration of Spent Lithium Iron Phosphate Cathodes through Coupled Lattice and Interface Repair

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional oleylamine‐assisted solvothermal strategy is introduced for coupled lattice and interface repair of S‐LFP cathodes. Benefiting from its strongly coordinating amine groups and long hydrophobic alkyl chains, oleylamine simultaneously acts as an intrinsic reductant, defect‐repair mediator, morphology stabilizer, and carbon/nitrogen ...

Seismic Performance of Reduced‐Strength Steel MRFs With SMA‐Based Superelastic Friction Dampers: An Experimental Investigation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Shape memory alloys (SMAs) exhibit excellent self‐centering capability due to their stress‐induced phase transformation, making them highly suitable for applications in resilient infrastructure. This study investigates the seismic performance of reduced‐strength moment‐resisting frames (MRFs) equipped with SMA‐based superelastic friction ...
