Abstract:

Porous Wall Hollow Glass Microspheres (PWHGMs) were developed by the Savannah River National Laboratory. What makes these microspheres unique is the interconnected porosity spread throughout their wall allowing various materials to travel from the surface to the hollow interior. With their characteristic porosity, the PWHGMs are a great tool for encapsulating or filtrating different materials. Unfortunately, there is little information available on the mechanical properties of PWHGMs. The main goal of this research was to develop a method to crush individual microspheres and statistically anal

Abstract:

Ultrasound irradiation of a protein or polymer solution at the air:water interface can be used to form hollow microspheres containing an air bubble. By introducing a layer of oil and sonicating the oil:water interface, microspheres containing an oil droplet are formed. The microspheres are stabilised by disulfide crosslinking, have diameters of between 1-20 mm and have a number of applications; gas filled protein microspheres are used as ultrasound contrast agents and oil filled microspheres are being developed for delivery of lipophilic drugs.

This master thesis examines the effect of hollow thermoplastic microspheres in coolroof paints. These types of paints are characterized by their high reflectivity forwavelengths up to 2.5 micrometers and high absorptivity in the IR region. Thethermoplastic microspheres were produced by Expancel®, a unit withinAkzoNobel®. Optical properties were measured using a UV-VIS-NIRspectrophotometer and FTIR. The paint systems were kept as simple as possible, onlycontaining binder, pigment and additive, thus limiting the study to relativecomparisons. TiO2 was used as standard pigment. The additive compon

Abstract:

Hollow low density microspheres were prepared by adsorbing kaolin nanoparticles onto a polystyrene (PS) template. A cationic polyelectrolyte, poly(diallydimethylammonium chloride), was initially adsorbed on the PS to render the surface cationic enabling the kaolin nanoparticles to form a shell structure due to electrostatic attraction forces. An increase in ionic strength by the addition of 0.1 M NaCl increased the amount of polyelectrolyte adsorbed at the PS surface. Solvent relaxation NMR experiments indicated that solvent molecules were bound at the PS surface suggesting attached polymer ch

Abstract:

This study aims to understand the behaviour of a novel elastomer where hollow microspheres are used as a particulate filler. The behaviour of elastomers filled with rigid particles, is fairly well understood, where the stiffness increases as the amount of filler material is increased, alternatively, foamed elastomers which are usually produced with either closed cells or open cells, have been shown to become softer as the volume of the voids are increased. When traditional foam materials are compressed they exhibit non-linear behaviour in three distinct phases, the cell walls firstly bend, the

Abstract:

For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB). It is therefore of great importance to reduce surface oxides before consolidation in order to improve mechanical properties. In this work, oxides were attempted to be reduced directly prior to the consolidati

Consequently, the concentration of drug released from PLGA-based carriers may fail to reach the therapeutic threshold promptly.

碩士<br>國立雲林科技大學<br>化學工程與材料工程系<br>106<br>The mechanical properties of rubber materials can be improved by the addition of silica particles. However, they increase the weight of rubber materials. Since hollow glass microspheres are low-density fillers, they are used to reduce the weight of rubber and plastic products. However, they decrease the strength of materials. The mechanical properties of rubber materials are related to the cross-link density. Both sulfur and peroxide have been widely used as cross-linking agents for rubbers. Sulfur vulcanization of rubber exhibits an excellent mechanical

Abstract:

The environmental concerns over the use of fossil fuels, and their resource constraints, as well as energy security concerns, have spurred great interest in generating electric energy from renewable sources. Solar and wind energy are abundant and potentially readily available. However, the generation of sustainable energies is generally intermittent and these energies have geographical limits which are relative to current large-scale energy generation facilities. To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) devices are becoming highly
