Hierarchical Uniform Supramolecular Conjugated Spherulites with Suppression of Defect Emission [PDF]
iScience, 2019 Easily processed, well-defined, and hierarchical uniform artificial architectures with intrinsic strong crystalline emission properties are necessary for a range of light-emitting optoelectronic devices. Herein, we designed and prepared ordered supramolecular spherulites, comprising planar conformational molecules as primary structures and multiple ...

Collimation of a spherical collisionless particles stream in Kerr space-time
, 2009 We examine the propagation of collisionless particles emitted from a spherical shell to infinity. The number distribution at infinity, calculated as a function of the polar angle, exhibits a small deviation from uniformity. The number of particles moving
