Systematic transformation of coordination polymer particles to hollow and non-hollow In(2)O(3) with pre-defined morphology.
Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles are formed from the calcination of non-porous CPPs.
متن کاملHollow Microsphere: a Review
The purpose of writing this review on Hollow microspheres is to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. Hollow microsphere promises to be a potential approach for gastric retention. The recent developments of FDDS including approaches to design single-unit and multiple-unit floating systems, mechanism of floating mi...
متن کاملHollow-core microstructured polymer optical fiber.
We have fabricated microstructured polymer optical fibers that guide light in a hollow core using the photonic bandgap mechanism. The hollow core allows the use of polymer fibers to be extended to wavelength ranges where material absorption typically prohibits their use, with attenuation lower than the material loss observed in the infrared. The fabrication method is similar to other microstruc...
متن کاملElastic properties of hollow colloidal particles.
The elastic properties of micrometer-sized hollow colloidal particles obtained by emulsion templating are probed by nanoindentation measurements in which point forces are applied to solvent-filled particles supported on a flat substrate. We show that the shells respond linearly up to forces of 7-21 nN, where the indentation becomes of the order of the shell thickness (20-40 nm). In the linear r...
متن کاملDrawing of Hollow Multilayered All-Polymer Fibers
We present a fluid dynamics model for the drawing of hollow multilayer polymer optical fiber. A newtonian model is considered assuming slender geometries. Hollow core collapse during drawing and layer thickness non-uniformity are investigated as a function of draw temperature, draw ratio, feeding speed, core pressurization and mismatch of material properties in a multilayer.
