Surface texture modification process

The most important feature affecting the functional and organoleptic properties of a protein is its surface structure. Surface structures affect the interaction of a protein with water or other proteins. By modifying the structure of the protein, particular functional and organoleptic properties are obtained. Functional properties of a protein are physicochemical characteristics that affect the processing and behavior of protein in food systems (Kinsella, 1976). These properties are related to the appearance, taste, texture, and nutritional value of a food system. Hydrolysis is one of the most important protein structure modification processes in the food industry. Proteins are hydrolyzed to a limited extent and in a controlled manner to improve the functional properties of a foodstuff. 

During the heterogeneous decomposition of formic acid on copper, the active metaUic phase undergoes sintering, sublimation and modifications of surface texture [25], By comparison with the behaviour of copper(II) formate [13], it is concluded that copper(l) formate is formed. Thus variations in the values of A and E, reported for the catalytic process may be attributed to a dependence of kinetic behaviour on the lifetime of the volatile participant, and thus upon metal mobility and reaction conditions [5], The decompositions of the copper formates and the catalytic decomposition of formic acid on copper metal thus include the participation of common intermediates, but these different reactions each consist of a sequence of several interdependent processes.

To elucidate the basic design parameteis for superoleophobicity, Zhao et al. [88] launched a systematic investigation using model pillar array surface with well-defined texture and geometiy. Figure 4.25 summarizes the surface texturing and chemical modification procedure for the fabrication of flie model textured surface. Details of the fabrication processes have been published elsewhere [88],... 

Surface modification (texturing) of polyimide through a metal clustering and migration process is reported. This process involves heat treatment of polyimide coated with a thin copper layer. Subsequent metallization of the textured surface leads to improved adhesion due to mechanical anchoring. Adhesion values of 7-10 lbs/in (ambient) and 4-6 lbs/in (after solder float) have been obtained. 

Surface modification/treatment of textile materials by chemical finishing processes is not environmentally friendly, as a result of which an alternative technology, laser irradiation has been widely adopted. By using laser irradiation, the textile materials can be structurally modified and their surface can be functionalized and textured. Here, two different examples of textile materials are presented and discussed in terms of laser treatment cotton,...
