FRP-to-Softwood Joints: Experimental Investigation [PDF]

open access: yes, 2011
A proper understanding of the interfacial behaviour between timber and bonded fibre-reinforced polymer (FRP) composites will assist in the rational and optimal design of FRP strengthening works for timber structures. To enhance this understanding, a series of single-lap FRP-to-timber joint shear tests are reported herein in which the strength of the ...

Mechanistic Insights Into Cellulose Dissolution in Solvents for Advanced Industrial Applications: A Systematic and Bibliometric Review

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability.

The Utilization of Silica–Lignin Composite as a Green Adsorbent for Cobalt and Lead Metal Ions in Aqueous Phase

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in environmental waste can pollute the environment and disrupt human health if not managed properly. Heavy metal contamination from industrial waste, particularly cobalt (Co) and lead (Pb), poses serious environmental and health risks due to their toxicity, persistence, and bioaccumulative nature.

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

open access: yesAsia-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 ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

open access: yesJournal of Applied Polymer Science, EarlyView.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating
