A Library of Versatile Lignocellulose‐Derived Monomers From 5‐(Chloromethyl)furfural

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
5‐(Chloromethyl)furfural (CMF), an emerging bio‐based platform molecule, was coupled with lignin‐derived compounds to afford a library of ligno‐cellulosic monomers under mild and scalable conditions. The products were isolated in high yields without chromatographic purification and further reduced to renewable diols, providing versatile building blocks

Effect of BaO on the structural, optical, and gamma-ray shielding properties of multicomponent borate glasses

Open Chemistry
The (55−x)B2O3-(22+x)BaO–13ZnO–5CaO–4MgO–1La2O3 (where x = 0, 4, 8, 12 mol%) glasses were prepared via the melt-quenching technique. FTIR spectral indicates the initial polymerization of the network followed by severe depolymerization beyond 26 mol% BaO.
