A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Magnetism for the Quantification of Sorption in Porous Materials From Liquid Media

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
This adsorption quantification technique uses external magnetic fields and a magnetic holder to measure mass changes during adsorption, making it universally applicable to any adsorbate. Unlike standard methods, it requires calibration only for the adsorbent rather than for every analyte.
