Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Wood‐based composite boards present a problem due to formaldehyde emissions from engineered particleboard, which pose health and environmental risks. This study explored the production of activated carbon (AC) from Scots pine (Pinus sylvestris) wood residues using phosphoric acid (H3PO4) as a chemical activator.

Restoration of human tooth enamel
BMEMat, EarlyView.Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Improved consolidation of silicon carbide [PDF]
Alpha silicon carbide powder was consolidated by both dry and wet methods. Dry pressing in a double acting steel die yielded sintered test bars with an average flexural strength of 235.6 MPa with a critical flaw size of approximately 100 micro m.

Effect of Cation Contamination of Gas Diffusion Layer on Water Management and Performance of PEMFCs
Carbon Energy, EarlyView.This study investigates Cr3+ contamination effects on GDL performance in PEMFCs, revealing hydrophobicity loss, pore structure changes, and Cr2O3 formation. Durability tests show a six‐fold increase in voltage decay rate, highlighting Cr3+‐induced degradation mechanisms that accelerate fuel cell failure.
