Selective Electrochemical Degradation of Lignosulfonate to Bio‐Based Aldehydes
ChemSusChem, Volume 16, Issue 8, April 21, 2023., 2023 Order from the chaos: An innovative electrochemical protocol for the degradation of lignosulfonate is presented. First lignosulfonate is oxidized electrochemically at planar nickel electrodes and then a thermal treatment at 170 °C follows. The complex polymer is degraded successfully into aldehydes such as vanillin and acetovanillone in good yields ...

Advanced Engineering Materials, Volume 25, Issue 8, April 2023., 2023 Microalloying additions of B, C, and Zr in cast and wrought Ni‐based superalloys are reviewed. Grain boundary segregation improves cohesion and strength. Excessive additions promote (co‐)precipitation of borides, carbides, and other inclusions, which benefit or deteriorate mechanical properties during processing.
