Kinetics of ε‐Caprolactone Ring Opening Polymerization: Experimental and Modeling Study

Journal of Polymer Science, Volume 64, Issue 15, Page 3226-3237, 1 August 2026.
We present a multi‐scale model for the ring‐opening polymerization of ε‐caprolactone to polycaprolactone (PCL), approximating final melt properties. We conducted batch experiments at various temperatures and reactant ratios. Using this data, we determined the kinetic parameters.

Assessing the Effects of Biodiesel Production on Sustainability: A Bayesian Two‐Stage Data Envelopment Analysis Approach

Sustainable Development, Volume 34, Issue 4, Page 5648-5668, August 2026.
ABSTRACT Sustainable development transforms production systems, requiring integrated environmental, social, and economic strategies. Energy systems are key agro‐industrial supply chains in developing countries. Brazil's soybean supply chain impacts Gross Domestic Product, mainly through exports.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Epoxidation of Cashmeran and Unprecedented Rearrangement to an α‐Carbonyl δ‐Spirolactone

European Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
A new strategy enables diastereoselective conversion of Cashmeran into a previously unknown α‐carbonyl δ‐spirolactone via epoxidation, Baeyer–Villiger oxidation, and acid‐catalyzed rearrangement. Structure and mechanism were confirmed by NMR, single crystal X‐ray diffraction, and computational studies. We report the epoxidation of Cashmeran followed by
