Abstract The use of cinnamic acid provides an approach to the research and development biobased plastics for reduction global warming caused by increasing amounts carbon dioxide in atmosphere. Cinnamic acids metabolic systems plants microorganisms have been extensively studied. These cinnamates are reactive ultraviolet (UV) light, polymers based on these exhibit unique properties. In this focus...

An approach to generalize any kind of collinear functional in density theory noncollinear functionals is proposed. This satisfies the correct limit for functional, guaranteeing that exact after generalization still spins. Besides, it has well-defined and numerically stable derivatives, a desired feature spin-flip time-dependent theory. Furthermore, provides local torque, hinting at its applicat...
