Hydrogen peroxide thermochemical oscillator as driver for primordial RNA replication

open access: yes, 2014
This paper presents and tests a previously unrecognised mechanism for driving a replicating molecular system on the prebiotic earth. It is proposed that cell-free RNA replication in the primordial soup may have been driven by self-sustained oscillatory ...

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

open access: yesInternational Journal of Chemical Kinetics, Volume 58, Issue 5, Page 199-209, May 2026.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Two‐Step Synthesis of a Chiral Fluorinated Alcohol With Silica‐Supported Enzyme RrADH in Batch and Continuous Flow Mode

open access: yesChemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
A two‐step process was transferred from batch to flow mode for the synthesis of (R)‐2‐fluoro‐1‐phenylethanol as a benchmark, consisting of a decarboxylative fluorination in aqueous media, followed by an enantioselective biocatalytic reduction of the prochiral intermediate with RrADH immobilized on silica supraparticles.

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Electrochemical Regioselective Chalcogenocyclizations of 2‐Alkynylbenzamides in Flow

open access: yesChemElectroChem, Volume 13, Issue 8, 15 April 2026.
A sustainable electrochemical method enables regioselective 6‐endo‐dig chalcogeno‐cyclizations of ortho‐alkynylbenzamides in continuous flow. Using diphenyl diselenide as an electroactive coupling partner, the process avoids metals and stoichiometric oxidants, offering scalable access to selenium‐containing heterocycles.
