process engineering is one of the major streams in textile engineering which refers to the engineering of textile chemical processes and associated applied science. The other three streams in textile engineering are yarn engineering, fabric engineering, and apparel engineering. The processes of this stream are involved or carried out in an aqueous stage.read more

In the step, however, by means of a freeze method is preferably performed. by means of the freeze method refers to an LCP film or the like in a frozen state. In this case, a liquid crystal polymer film can be ground smoothly, so that powder of fine particle diameter can be obtained efficiently.read more
, also known as milling, is a process of taking materials in a liquid or slurry form and reducing the particles by breaking them apart or shearing them down in size. Visit the Custom Milling & Consulting website to learn more about our capabilities.read more
Promising compositions of electrolyte materials can be obtained with several compositions by various synthesis routes, like regular melt- quench process or producing NASICON- glass ...read more
The effect of glass, OTS-SAM-coated glass, or PTFE and surfactant treatment anionic or nonionic on shear adhesion was tested using a repeated-measures MANOVA. Each gecko was tested in all combinations of treatments, which effectively removed the need to account for individual differences in such features as area of the toe pads.read more
Belt has become an important production process, in some cases replacing conventional operations such as the of camshafts. Belt speeds are usually in the range of 2,500 to 6,000 ft/min. Machines for abrasive-belt operations require proper belt support and rigid construction to minimize vibration.read more
The influence of the , oxidation pretreatment, and enzymatic hydrolysis on the structure of wheat straw particles was evaluated by SEM. SEM was carried out in a JEOL microscope model JSM‐5900. Prior to analysis the samples were coated with gold to a thickness of ∼7 nm using a Polaron SC7620 sputter coater.read more
