Synthesis of Amides from Amines and Esters Under Hydrothermal Conditions

open access: yesChemistryOpen, Volume 15, Issue 2, February 2026.
In this study, we explore the amide synthesis under hydrothermal conditions, using amines and esters as the starting materials. Proposed major pathway starts with ester hydrolysis, followed by condensation between carboxylic acids and amines. The amide yield is dependent on the substrate structure, solution pH, and the presence of dissolved metal salts.

D‐Optimal Design for Enzymatic Ring‐Opening Polymerization of ε‐Caprolactone: Toward Sustainable Polyester Synthesis Using Biobased Solvents

open access: yesJournal of Polymer Science, Volume 64, Issue 3, Page 817-824, 1 February 2026.
A D‐optimal design of experiments maps the influence of key reaction parameters on enzymatic ε‐caprolactone polymerization. Thus linking multivariate conditions to conversion, molar mass characteristics, and by‐product formation, whilst demonstrating that biobased solvents offer viable, sustainable media for polyester synthesis.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...
