Surface wear and roughness of experimental composites containing calcium orthophosphate particles following toothbrush abrasion

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This study evaluated experimental composites containing dicalcium phosphate dihydrate (DCPD) particles for toothbrush wear and roughness. Composites containing bisphenol‐A glycidyl dimethacrylate/triethylene glycol dimethacrylate with 50 vol% inorganic fraction consisting of barium glass and DCPD (35:15 and 15:35 vol%) or barium glass only ...

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4102-4126, 10 March 2026.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as
