The microencapsulation of volatile phase change materials is an important and challenging area for low-temperature thermal energy storage. Our previous studies have effectively addressed the challenge long-term core retention also indicated that quality obtained poly(urea-formaldehyde) microcapsules highly affected by various process parameters, including reaction temperature, initial pH, time,...

The present study applied extended Taguchi method through a case study in straight turning of mild steel bar using HSS tool for the optimization of process param. The study aimed at evaluating the best process environment which could simultaneously satisfy requirements of both quality as well as productivity with special emphasis on reduction of cutting tool flank wear, because reduction in fla...

Taguchi optimization method (L32 orthogonal array) was applied as an experimental design to determine optimum conditions for methylene blue dye removal from aqueous solutions by electrocoagulation (EC). Various electrocoagualtion parameters such as initial pH, time of electrolysis, concentration of dye, electrodes gap, applied current, solution temperature, amount of supporting electrolyte, des...

Compared with traditional material subtractive manufacturing technologies, rapid prototyping is a layer-based material additive process and can produce a 3-D freeform object with a CAD-defined geometric model directly. As one of the advanced rapid prototyping and manufacturing processes, the direct metal laser sintering (DMLS) process gives designers the possibility to build parts of almost any...

High engineering requirements of shock absorbers have increased interest in auxetic materials, which higher specific energy absorption performance compared to conventional solid absorbers. Last decade, many optimization studies were conducted improve the tubular structures. Most focused on adding inner and outer shells thin-walled with different types lattice structures enhance cylindrical sand...
