Cellulose processing from biomass and its derivatization into carboxymethylcellulose: A review
Scientific African, 2022 Many physical, chemical, and/or enzymatic treatments have been used to open the structure of lignocellulosic biomass, separate its components and obtain cellulose. The alkaline-bleaching treatment is most preferred in terms of reagent availability.

Chemoselective Formation of Unsymmetrically Substituted Ethers from Catalytic Reductive Coupling of Aldehydes and Ketones with Alcohols in Aqueous Solution [PDF]
, 2015 A well-defined cationic Ru–H complex catalyzes reductive etherification of aldehydes and ketones with alcohols. The catalytic method employs environmentally benign water as the solvent and cheaply available molecular hydrogen as the reducing agent to ...

Asia-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.

Electrooxidative Divergent Halocyclizations of Ambident Amides
Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.Electrooxidation enables tunable halocyclization of ambident amides, yielding either C–O or C–N products through ionic or radical pathways, respectively. While detailed experimental and analytical mechanistic studies highlight mode‐dependent selectivity, in silico experimentation provided insight into the energetic origin of this divergence.

Carbasugar analogues of galactofuranosides: α-O-linked derivatives
Beilstein Journal of Organic Chemistry, 2010 Using an indirect method, we have synthesised α-linked carbasugar analogues of galactofuranosides for the first time. Ring opening of a β-talo configured carbasugar 1,2-epoxide by alcohol nucleophiles under Lewis acidic conditions proceeded with very ...

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication
Chemistry – A European Journal, EarlyView.This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

Bifunctional Lewis and Brønsted acidic zeolites permit the continuous production of bio-renewable furanic ethers [PDF]
, 2017 The catalytic valorisation of bio-renewable feedstock often relies upon multi-stage processing of highly-functionalised substrates, resulting in selectivity and processs engineering challenges. Herein, we demonstrate that a bifunctional zeolitic material,
