Small but strong carbon nanotubes (CNTs) are fillers of choice for composite reinforcement owing to their extraordinary modulus and strength. However, the mechanical properties nanocomposites still much below those parameters individual nanotubes. The gap between expectation experimental results arises not only from imperfect dispersion poor load transfer also unavailability polymers that can be effectively utilized within composites Aramid nanofibers (ANFs) with analogous morphological...

Elastomers such as polyurethanes usually possess low stiffness, and the addition of traditional fillers typically results in a moderate improvement. Aramid nanofibers (ANFs) represent one most promising nanoscale building blocks for high-performance nanocomposites.

Abstract Single‐atomic transition metal–nitrogen–carbon (M–N–C) structures are promising alternatives toward noble‐metal‐based catalysts for oxygen reduction reaction (ORR) catalysis involved in sustainable energy devices. The symmetrical electronic density distribution of the M─N 4 moieties, however, leads to unfavorable intermediate adsorption and sluggish kinetics. Herein, a Fe–N–C catalyst with asymmetry induced by one nearest carbon vacancy adjacent Fe─N is conceptually produced, which...
