The NdFeB magnets with millimeter sizes, typically between 0.5 and 12 mm, have been widely used in electronics, acoustic products, and micro-motor. Preparing these magnets by the traditional sintering and bonding techniques is associated with complicated process and sacrificed density and machineability of the magnet. Aiming at the huge market requirements and facing those technical problems, the...
Aqueous solutions of dipotassium tetrathiafulvalene dicarboxylate (1), potassium ferricyanide and poly(vinyl alcohol) were used to cast air-stable, flexible and electrically conductive films. Casting at 80-95°C formed a network of microcrystals oriented in the film plane. Spectroscopic studies showed that these crystals contain π-stacks of the cation radical 1 + . No evidence for mixed valence...
