Formylation with "Supercritical” CO2: Efficient Ruthenium-Catalyzed Synthesis of N -Formylmorpholine [PDF]

open access: yes, 2018
Formylation of morpholine with "supercritical” CO2 using the bidentate ruthenium catalyst RuCl2(dppe)2 affords high N-formylmorpholine production rate at almost 100% selectivity. The solventless reaction could be an interesting alternative to the present

Direct Consolidation of Copper–Graphene Composite by Rotary Swaging

open access: yesAdvanced Engineering Materials, EarlyView.
The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...
