A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each ....A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each other or adhere to surfaces. The knowledge gained in this project will enable improvements to be made in the efficiency of processes such as those listed above.Read moreRead less
A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer proces ....A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer processing temperature, to exfoliate and disperse nanosheets in polymers. It is expected to generate new knowledge of the structure-property relationships and fracture mechanisms of these composites, for industry to scale up this technology and to develop new product.Read moreRead less
