Graphene Materials for Sustainable Energy Applications: A Contemporary Perspective

Carbon Energy, EarlyView.
ABSTRACT Graphene has garnered significant attention as a promising material with great potential for contributing to sustainable energy initiatives, such as RE100 (100% renewable energy initiative) and CF100 (100% carbon‐free initiative). This review aims to explore the potential of graphene for advancing renewable energy applications by highlighting

Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Dry‐Processed Dual‐Layer Thick Cathodes With Distinct Ni Compositions to Mitigate Degradation in Lithium‐Ion Batteries

EcoEnergy, EarlyView.
Dry‐processed thick cathodes can increase battery energy density, but uneven reactions accelerate degradation. This work shows that the position of high‐nickel cathode material is critical. Placing NCM811 near the current collector and NCM622 near the separator reduces local overreaction, particle cracking, metal crossover, and interphase growth ...

Models for Punching Shear Capacity in Concrete Slabs

, 2013
Model Code 2010 was published in the spring of 2012 by the International Federation for Structural Concrete (fib), and presents a whole new model for punching shear design. Whereas the method for punching shear design in Eurocode 2 is mainly empirical, the method in Model Code 2010 is grounded in a physical model called the Critical Shear Crack Theory.

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Cononsolvency‐Assisted Fabrication of Hydrogels and Microgels With Tunable Porosity, Diffusivity and Stiffness

Macromolecular Rapid Communications, EarlyView.
The cononsolvency of poly(dimethyl acrylamide‐co‐hydroxyethyl acrylamide) copolymers in water‐acetonitrile mixtures enables the synthesis of hydrogels with finely tuned porosity. Optimized for droplet‐based microfluidics, this approach facilitates the fabrication of porous microgels with tunable mechanical and diffusion properties, offering precise ...

Explainable machine learning models for punching shear capacity of FRP bar reinforced concrete flat slab without shear reinforcement

Case Studies in Construction Materials
Existing semi-empirical formulas for predicting punching shear capacity in FRP bar reinforced concrete flat slabs without shear reinforcement often prove inaccurate and unstable. This is primarily due to limited modeling data, inadequate consideration of

Solvent‐Tuned DLP 3D‐Printed PNVCL Hydrogels With Enhanced Thermoresponse

Macromolecular Rapid Communications, EarlyView.
DLP 3D printing of PNVCL hydrogels remains challenging due to a trade‐off between printability and thermoresponsive performance. Here, DEG‐tuned P(NVCL‐DVA) organohydrogels were successfully 3D‐printed and subsequently solvent‐exchanged with water. The optimized hydrogels exhibited interconnected porous structures, high water uptake and rapid thermo ...

Immunomodulatory, Antibacterial, Antioxidative and EGF‐Delivering Hydrogel Remodels Wound Microenvironment for Infected Diabetic Wound Healing

National Materials, EarlyView.
In this study, we engineered an antibacterial, antioxidative and epidermal grow factor‐encapsulated multifunctional hydrogel for the repair of chronic and refractory wounds. The hydrogel markedly promoted wound healing in rat models of diabetic foot ulcers and infected wounds by modulating wound microenvironment.
