Abstract One of the most successful processes for extracting, recovering, and recycling metals from wastewater is adsorption utilizing natural activated carbon, such as banana peel waste. This advantageous a treatment sector since carbon less expensive than conventional carbon. The aim this research to determine optimum contact time at removing heavy colour using stirrer tub (pilot scale). Phys...

Compared with thrombus dissolution using only thrombolytic agents, an advanced therapy of direct stirring the blood clot can yield shorter recanalization time and higher velocity. Our previous research presented design a novel micro-stirrer, which convert longitudinal vibration into transverse eventually generate opposite at end-effort, like scissor, for efficient acceleration. Transverse is mo...

This study aimed to characterize Phase Change Materials (PCM) by improving their properties using shape stabilization; this was achieved adding nanoparticles as a support material. PCM soy wax modified two nanoparticles, graphene, and MAXene Ti3AlC2. The synthesis process comprised stirring magnetic stirrer ultrasonication an ultrasonic processor with various percentages of 0.1, 0.5, 1 wt.% nan...

This work mainly focuses on the development of a novel type chemically activated electrodes from cotton yarn by carbonization and chemical activation. Chemical activation is employed in order to obtain high specific capacitance, energy power density. The zinc oxide was prepared sol – gel method pH should be range 9 11. ZnO/CCY electrode it stirred with magnetic stirrer. performance evaluated us...
