Toward Sustainability: Intensification of Light‐Driven Whole Cell Biocatalysis

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Whole‐cell, light‐driven biotransformations in photoautotrophic microorganisms offer the potential for higher atom economy by directly harnessing reducing equivalents and oxygen generated through natural photosynthesis. Current advances include the development of strains with improved growth rates and reactor designs that mitigate self‐shading ...

Synthesis of fused cyclic chromene and alicyclic chromene derivatives from 2-amino-4-[4-(dimethylamino)phenyl]5-oxo-4H,5H-pyrano [3,2-c]chromene-3-carbonitrile

open access: yesAl-Mustansiriyah Journal of Science, 2017
Derivatives of fused cyclic chromene and alicyclic chromene were synthesized starting from 2-amino-4-[4-(dimethylamino)phenyl]5-oxo-4H,5H-pyrano [3,2-c]chromene-3-carbonitrile. The structures of the synthesized compounds were elucidated by spectral data :

Flavouring Group Evaluation 82 Revision 2 (FGE.82Rev2): Consideration of epoxides evaluated by JECFA

open access: yesEFSA Journal, Volume 24, Issue 4, April 2026.
Abstract The Panel on Food Additives and Flavourings (FAF) of the European Food Safety Authority was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No.

Wide Band Gap Boron Nitride Nanodots‐Incorporated Polyetherimide Dielectrics for High‐Temperature Dielectric Energy Storage

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
The inherent conjugation effects between molecular chains in PEI dielectrics induce substantial energy loss escalation at elevated temperatures. This study incorporated BNNDs into PEI films, successfully achieving effective capture of motion charges under high‐temperature conditions.

Gas‐Phase Dehydrogenation of Perhydro Benzyltoluene Using a Commercial Pt on Alumina Catalyst–Stability and Kinetics

open access: yesEnergy Technology, Volume 14, Issue 3, March 2026.
Dehydrogenation of H12‐BT is normally conducted in a multiphasic reaction whereas hydrogen release lowers the partial pressure of H12‐BT and induces H12‐BT evaporation. Due to H12‐BT evaporation major parts of the released hydrogen origin from gas phase dehydrogenation.
