Thermal behavior of palm stearin (PS) and palm olein (PO) was explored by monitoring peak temperature transitions by differential scanning calorimetry (DSC). The fatty acid composition (FAC), isothermal crystallization kinetics studied by pulsed Nuclear Magnetic Resonance (pNMR) and isothermal microstructure were also compared. The results indicated that the fatty acid composition had an import...
In this study, the effect of mechanical alloying on the microstructure and phase constituents of Mg-6Al-1Zn-1Si system was investigated. To understand the thermal behavior, isothermal annealing was performed at three different temperatures of 350, 400 and 450 °C for 1h. The results showed the grain size initially decreases with increasing the milling time up to 35h and then slightly increases. ...
Non-isothermal laser-based powder bed fusion (LPBF) of polymers suggests the potential for significantly extending range materials applicable powder-based additive manufacturing polymers, relying on absence a material-specific processing window. To allow support-free at build chamber temperature 25 °C, applied strategies comprise combination fractal exposure and locally quasi-simultaneous disti...
The synthesis problems of non‒isothermal water networks have received considerable attention throughout academia and industry over the last two decades because of the importance of simultaneously minimising water and energy consumption [1]. Most papers have addressed this issue only by considering heat integration between hot and cold water streams. In this study, the scope of heat integration ...
A sorption-enhanced process for hydrogenation of CO2 to methanol was designed and investigated by mathematical modelling techno-economic analysis. The methodology combined dynamic the cyclic reactor operation with pseudo-steady state overall process. With continuous adsorption water in process, highly pure (>99%) produced without downstream distillation. cycle optimized maximize production rate...
