Fluoroarene Strategy in Total Synthesis of Natural Flavonoids

AbstractVicenin-2, a naturally occurring bis-C-glucosyl flavonoid, was synthesized by exploiting a sequential C-glycoside formation and aromatic nucleophilic substitution (SNAr reaction) of the fluoroarene derivative, i.e., 1,3,5-trifluorobenzene, converting fluorine atoms to oxygen function.

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.

Aloe vera–Based Green Synthesis of Silver Nanoparticles With Characterization, Potent Antibacterial and Antioxidant Properties

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Green synthesis has emerged as a suitable alternative to the traditional method for manufacturing nanoparticles (NPs) as it provides a safer, sustainable, healthy, and environmental path for the NPs synthesis. Silver nanoparticles (AgNPs) were prepared using a green method with locally sourced Aloe vera leaf extract.

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...
