Preparation and manufacturing of nanomembranes based on ramie fiber using electrospinning technique

In this study, ramie fibers were used to fabricate nanomembranes, which are expected to be able to filter micron/nano-sized particles. The ramie fibers were processed into cellulose pulp and processed into cellulose acetate. Ramie cellulose acetate is the basic material for making nanomembranes through an electrospinning process. Nanomembrane characterization was carried out using FTIR, thermogravimetry analysis (TGA),...

Simulation of atmospheric crude distillation column for processing 12.5 bpd crude oil throughput

Crude oil refining in compact units has become crucial for developing economies due to the soaring demand for refined products and the prohibitive costs of large conventional refineries. Many countries find it challenging to build and maintain these massive plants, leading them to adopt cost-effective, simplified distillation units. This study specifically analyzes the design of a small-scale crude oil distillation...

Effect of calcination temperature on the photocatalytic activity of Ni-Doped TiO2 nano particles

This research work presents the preparation of pure undoped TiO2 and 0.5 wt.% Ni-doped nanoparticles through the sol-gel method using titanium tetra isopropoxide as the titanium source and nickel nitrate hexahydrate as the nickel source. The prepared samples were calcined at 450, 500, 550, 600, 700, and 800°C and analyzed for energy band gap, surface area, particle size, morphology, and purity using UV-Vis DRS, BET,...
