Improvement of Concrete Durability and Strength with Epoxy Resin Concrete

European Journal of Theoretical and Applied Sciences
Portland cement concrete has wide applications in construction owing to its good strength and relatively low cost. However, exposure to extreme environmental conditions has many significant drawbacks. Cracking due to mechanical stresses, chemical degradations, and extreme fluctuations in temperature accelerate the deterioration of concrete by way of ...

A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

Advanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Impact of Silica Sand on Mechanical Properties of Epoxy Resin Composites and Their Application in CFRP–Concrete Bonding

Applied Sciences
Premature debonding between carbon fiber-reinforced polymer (CFRP) and concrete is a critical issue in structural reinforcement applications, often leading to a significant reduction in the load-carrying capacity of the system.

Precision Synthesis of Biomass‐Derived Graphene‐Like Carbon With Tailored Crystallinity via Controlled Flash Joule Heating

Carbon Energy, EarlyView.
A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.
