Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Structure–Activity Relationships in Methyl‐Driven Overhauser Effect DNP

open access: yesChemistry – A European Journal, EarlyView.
Dynamic nuclear polarization (DNP) was investigated in a wide array of methyl‐containing Blatter radicals to identify design principles for the synthesis of an Overhauser DNP polarizing agent. Fourteen different radicals were synthesized, which revealed that only radicals possessing sterically unhindered methyl groups in sites of high spin density were

Amino Acid Modified Polymer Mesh for Removal of the Heavy Metal Ions Pb2+, Hg2+, Cu2+, and Ni2+ From Aqueous Solutions

open access: yesChemie Ingenieur Technik, EarlyView.
Adsorbents for cations of copper, lead, mercury, and nickel are obtained via grafting polymer mesh with an acrylic acid copolymer and subsequent functionalization with an amino acid. A distinct influence of the type of amino acid on the adsorption occurs.

AutoGCA—A Software Tool for the Automated Analysis of Gas Chromatograms

open access: yesChemie Ingenieur Technik, EarlyView.
The automation of tedious manual or semi‐automated analysis of gas chromatograms offers significant time savings in analytical chemistry. An automated approach is proposed that works even for gas chromatography datasets with highly overlapping or baseline distorted peaks. ABSTRACT Gas chromatography (GC) is an important tool in analytical chemistry and

Coupled heat and mass transfer in reactive parallel‐plate flow: A perturbative Graetz model with modal symmetry and Arrhenius kinetics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.
