DOI: 10.1002/adma.202208284
Abstract: Electrochemical oxidative lignin cleavage and coupled 2‐furaldehyde reduction provide a promising approach for producing high‐value added products. However, developing efficient bifunctional electrocatalysts with noble‐metal‐like activity still remains a challenge. Here, an efficient electrochemical strategy is… read more here.

DOI: 10.1002/app.45398
Abstract: Resorcinol-formaldehyde adhesives can reinforce stress fractures that appear from wood surface preparation. Researchers have found that applying the resorcinol-formaldehyde prepolymer, hydroxymethylated resorcinol, to the surface of wood improves the bond strength of epoxy and polyurethane… read more here.

DOI: 10.1002/bip.23520
Abstract: The redeposition of lignin to the fiber surface after organosolv pretreatment was studied using two different reactor types. Results from the conventional autoclave reactor suggest that redeposition occurs during the cooling down stage. Redeposited particles… read more here.
