Tibetan singing bowls
We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes ...
متن کاملVinca Alkaloids
Vinca alkaloids are a subset of drugs obtained from the Madagascar periwinkle plant. They are naturally extracted from the pink periwinkle plant, Catharanthus roseus G. Don and have a hypoglycemic as well as cytotoxic effects. They have been used to treat diabetes, high blood pressure and have been used as disinfectants. The vinca alkaloids are also important for being cancer fighters. There ar...
متن کاملBuilding Bowls for Miscellaneous Media
The features we present of the augmented bowl have been designed to exploit our commonsense understandings and everyday uses of container-like objects. As we’ll explain, in choosing the features, we’ve attempted to build on the ways in which physical content can be casually added to or retrieved from a bowl with little to no thought. We’ve also tried to capture the way bowls loosely contain the...
متن کاملSynthesis of nano-bowls with a Janus template.
Colloidal particles with two or more different surface properties (Janus particles) are of interest in catalysis, biological imaging, and drug delivery. Eccentric nanoparticles are a type of Janus particle consisting of a shell that envelops the majority of a core particle, leaving a portion of the core surface exposed. Previous work to synthesize eccentric nanoparticles from silica and polysty...
متن کاملInteraction between anions and substituted molecular bowls.
Complexes formed by anions and substituted molecular bowls were studied by means of computational methods. The bowls consisted of corannulene molecules substituted with five or ten F, Cl, or CN groups, whereas Cl(-), Br(-) and BF(4)(-) were the anions considered. Substitution with F, Cl and CN hardly affects the geometry of the bowl, but produces an inversion of the molecular electrostatic pote...
