Notched impact behavior of polymer blends: Part 1: New model for particle size dependence [PDF]
, 2009 A model is proposed to explain the observed relationships between particle size and fracture resistance in high-performance blends, which typically reach maximum toughness at particle diameters of 0.2–0.4 μm.

Angewandte Chemie, Volume 137, Issue 47, November 17, 2025.Diese Arbeit integriert die anodische H2O2‐Erzeugung mit Ammoximierung für eine effiziente Oximsynthese. Durch die Regulierung des lokalen pH‐Wertes durch Elektrolytoptimierung erreicht das System eine Elektroneneffizienz von 81 % und eine H2O2‐Nutzung von 98 % und bietet damit eine verallgemeinerbare Strategie für elektrochemisch‐chemische ...

Transfer molding of PMR-15 polyimide resin [PDF]
, 1985 Transfer molding is an economically viable method of producing small shapes of PMR-15 polyimide. It is shown that with regard to flexural, compressive, and tribological properties transfer-molded PMR-15 polyimide is essentially equivalent to PMR-15 ...
