Evaluation of Air Inlet Configuration's Effect on Biochar Properties From African Mesquite Pod Carbonization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...

Optimization and Characterization of Aspirin‐ and Ibuprofen‐Loaded Lipid‐Based Nanoparticle Synthesis for Antibacterial Activity and Cytotoxic Effect

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Lipid‐based nanoparticles (LNPs) are favored for drug delivery because of their low toxicity, high biocompatibility, ability to self‐assemble into nanoparticles, and ability to enhance drug bioavailability, thereby improving drug release modulation and pharmacokinetics.

Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Composition of the L5 Mars Trojans: Neighbors, not Siblings

, 2007
Mars is the only terrestrial planet known to have Tro jan (co-orbiting) asteroids, with a confirmed population of at least 4 objects. The origin of these objects is not known; while several have orbits that are stable on solar-system timescales, work by ...

Development and Characterization of Cellulose Films Incorporating Vitamin A and E‐Loaded Liposomes

Journal of Applied Polymer Science, EarlyView.
Liposome‐cellulose films deliver UV‐light shielding, wetting, and high rigidity for green tattoo aftercare. ABSTRACT This study introduces cellulose films enriched with vitamin A/E liposomes as sustainable, bioactive dressings for tattoo aftercare. Morphological analysis showed a smoother, more continuous microtexture than the neat cellulose films ...

Tailored Dual Responsive Hybrid Gelatin Methacryloyl/Poly[2‐(Dimethylamino)Ethyl Methacrylate] Hydrogels for Efficient Ibuprofen Release in Topical Applications

Journal of Applied Polymer Science, EarlyView.
GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated

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

Journal 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
