Synergistic Effects of Silica and Calcium‐Based Dual Admixtures on the Flowability, Microstructure, and Strength Development in Low‐Carbon Concrete

Applied Research, Volume 5, Issue 4, August 2026.
ABSTRACT Eco‐friendly construction practices have emerged as a cornerstone of modern development. Due to the substantial carbon emissions from cement production, there is a growing demand for supplementary cementitious materials. This study investigated the synergistic effects of two different wastes, silica‐rich rice husk ash (RHA) and calcium‐rich ...

An Analysis of Great Tit Egg Traits Across the City Mosaic: Urbanisation Does Not Affect Egg Size and Pigmentation Patterns

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Based on data from over 550 great tit (Parus major) eggs collected in the city mosaic, this research finds no effect of urbanisation on egg volume or pigmentation patterns. These results suggest that urban‐driven environmental pressures may not be as strong or directional during the egg laying phase as they are at later stages of reproduction ...

Carbonation and chloride penetration resistance of sustainable structural concrete with alkali-activated and ordinary Portland cement binders: a critical review

Sustainable Structures
The use of concrete with alkali-activated binders in structural engineering applications is restricted by the uncertainty surrounding its long-term performance.

Carbon Fiber used in Concrete

International Journal of Advanced Research in Science, Communication and Technology
Carbon fiber-reinforced concrete (CFRC) is an emerging material that enhances the mechanical properties and durability of traditional concrete by incorporating carbon fibers. In India, with the construction sector growing rapidly and facing challenges related to durability and sustainability, CFRC can offer a solution.

CO2‐Derived Architected Carbons for Sustainable Energy Conversion and Storage

EcoMat, Volume 8, Issue 8, August 2026.
CO2‐derived carbon architectures are systematically engineered via thermochemical, electrochemical, and hybrid pathways to tailor electronic structure, interfacial charge transfer, and catalytic functionality. These materials demonstrate versatile performance across electrocatalysis and energy storage, establishing a coherent framework that links ...

Recent History of Surface Ocean Acidification Extremes That Compound Marine Heatwaves

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract Compound extremes are of concern for ocean health, such as when ocean acidification extremes (OAX) and marine heatwaves (MHW) co‐occur. These compound events (OAX∩ $\,\cap \,$MHW) may amplify stress beyond the impact of each driver alone, yet their historical distribution remains poorly quantified.

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other
