Carrageenans are major gel forming polysaccharides in the extracellular matrix of the red macroalga Chondrus crispus. These galactans are made of linear chains of repetitive disaccharide motifs based on d-galactose residues alternately linked by β-1,4 and α-1,3 glycosidic bonds. A definite number of disaccharide motifs are known, based on their reg...

New lithiated NaSICon-typed phosphates LiNiV2(PO4)3/C (LNVP/C) and LiMnV2(PO4)3/C (LMVP/C), prepared via the sol-gel synthesis route, are investigated as negative electrode materials for Li ion batteries (LIBs). This study discusses the structural and morphological features of the synthesized materials and reports their electrochemical performance/...

Sulfidic hot springs harbor unique microbial communities and are important in mercury (Hg) species transformations, although the fine scale drivers of these processes remain poorly understood. Here we studied Hg speciation in water, biofilms, and sediment across three sampling seasons in a French sulfidic hot spring with low Hg concentrations. Micr...

A series of diphenyliodonium and tetrabutylammonium salts of vanadium (+V) and iron (+III) mono and disubstituted polyoxotungstates was designed and tested as visible light photoinitiators for the free radical polymerization of acrylates or the cationic polymerization of epoxides. Interestingly, these polyoxotungstates could act as efficient photos...

Mg fluorinated alkoxyborate-based electrolytes are promising candidates for rechargeable Mg batteries. In this work, we investigate a series of Mg alkoxyborates with a different degree of anion fluorination in terms of their physicochemical properties, Mg metal anode, and organic cathode electrochemical performance, as well as Mg metal/electrolyte ...

Agricultural organic wastes can leach dissolved organic matter (DOM) into surrounding water bodies, establishing them as significant sources of aquatic DOM. Given the importance of DOM in biogeochemical cycling of mercury (Hg), this DOM may mediate divalent Hg (Hg(II)) reduction, a process that remains poorly understood. This study investigated Hg(...

Lysozyme-responsive nanoparticles were fabricated using a hydrophilic protein (gelatin type A) as the core and a hydrophobic polysaccharide (chitosan) as the shell. In this study, curcumin was used as a model molecule for encapsulation and promoted the aggregation of gelatin nanoparticles. Transglutaminase catalyzed both intramolecular cross-linkin...

Macromolecular drug delivery systems are engineered nanotechnologies used for the targeted delivery and controlled release of therapeutic agents to a specific biologic target, a rapidly growing need in the age of tailor-made therapeutic treatments. The rise of drug delivery systems stems from their ability to solve the pharmacological issues that o...
