A simple ESR identification methodology for Electrolytic Capacitors conditon mo...

Electrolytic capacitors are usually used in power electronic systems for smoothing, energy storage or filtering. They have the best overall performance for these objectives being a critical element in the design of these systems, in several applications, with different requirements. But, infortunately, in most cases, they are the most life-limiting device. The expected life of electrolytic capacitors depends on...

Muscicapines, a new class of guaiane-type sesquiterpene alkaloids from Croton m...

Three new guaiane-type sesquiterpene alkaloids, muscicapine A (1), muscicapine B (2), and muscicapine C (3) were isolated from the roots of Croton muscicapa. The structures were established by analysis of spectroscopic data, mainly 1D and 2D NMR and MS. This is the first report of a new class of guaiane-type sesquiterpene alkaloids.
