Alumina–Silica Hybrid Reinforcement in Jute/Epoxy Composites: Mechanical Characterization and Modified Rule of Mixtures for Strength–Toughness–Hardness Optimization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural fiber composites offer sustainable alternatives to synthetic materials but need performance enhancement for structural applications. This study investigates the mechanical behavior of jute fiber–reinforced epoxy composites modified with alumina–silica hybrid fillers at varying compositions and loadings.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Volumetric stability control of steel slag and its mechanism research [PDF]

E3S Web of Conferences
Free calcium oxide (f-CaO) in steel slag is converted to calcium hydroxide (Ca(OH)2) on contact with water, accompanied by significant volume expansion, a property that greatly limits the widespread use of steel slag.

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

Archaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of
