Exploring the Role of Energy Consumption and Labour Productivity in Understanding the Effects of Climate Change on International Trade

The World Economy, EarlyView.
ABSTRACT Climate change can influence international trade through several mechanisms, including infrastructure damage, disruptions to energy systems and reductions in labour productivity. Recent evidence for the United States also suggests that energy consumption responses play a central role in transmitting the real effects of natural disasters. Using

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3692-3713, July 2026.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Dynamic modeling of three-phase upflow fixed-bed reactor including pore diffusion [PDF]

, 2002
The dynamics of a three-phase upflow fixed-bed reactor are investigated using a non-isothermal heterogeneous model including gas–liquid and liquid–solid mass transfer and diffusion/reaction phenomena inside the catalyst.

Synthesis and Evaluation of Aromatic Sulfonamide and Disulfonamide Derivatives as Dengue Virus NS3–NS5 Interaction Inhibitors

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
A synthetic methodology for the preparation of asymmetric benzene‐1,4‐disulfonamides was developed and applied to generate potential anti‐dengue virus (DENV) compounds. Guided by computer‐assisted structural rationalization, we designed synthetically more accessible analogs with reduced toxicity that interact with the DENV NS5 domain, thereby ...

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.
