Effect of dual flocculant by unmodified manihot esculenta starch and aluminium sulphate on the removal of chemical oxygen demand optimized by response surface methodology
Published 2024“…Besides the performance of COD removal increased, the dosage of the chemical coagulant was reduced by up to 64% at the optimum condition of 18 mg/L alum dosage, 307 mg/L starch dosage, pH 9, and 27 mins settling time. The analysis of variance (ANOVA) indicated that the quadratic model was significantly developed with a p-value < 0.05. …”

Green approach to treat institutional wastewater by using cassava peels starch (CPS) as coagulant aid
Published 2018“…Removal efficiency of dual coagulant (alum+CPS) were achieved at optimum dosage of 40:60 mg/L at pH 8 with 60 mins settling time with removal efficiency of COD (41%), TSS (86%) and Turbidity (91%). …”

Novel miniature microwave quasi-elliptical function bandpass filters with wideband harmonic suppression
Published 2017“…This technique is shown to provide a sharp 3-dB roll-off and steep selectivity skirt with high out-of-band rejection over a wide frequency span. In addition, the 3-dB fractional bandwidth of the filters is shown to be controllable by manipulating the filter’s geometric parameters. …”

Green synthesis, characterization and laser irradiation of silver nanoparticles and its bimetallic nanoparticles
Published 2020“…In contrast, Ag/Cu NPs were synthesized by mixing Cu solution (1, 3, 5 and 7 mM) with Gre-Ag NPs at room temperature and left for 10 mins. Moreover, the silver nanostructures (Ag NSs) was fabricated by manipulating Gre-Ag NPs with diode laser 450 nm at different times. …”

In vitro bioactivities of anodised titanium in mixtrue of B-Glycerophosphate and calcium acetate for biomedical application
Published 2016“…The parameters for anodic oxidation method such as applied voltage (50-350 V), current density(10-70 mA.cm-2), electrolyte concentration (0.02 M β-GP + 0.2 M CA, 0.04 M β-GP + 0.04 M CA) , anodising time (5-10 mins), agitation speed (300-1500 rpm), ultrasonic amplitude (20-60 μm) and bath temperature (4-100 °C) were varied to investigate the impact on the surface properties of titanium. …”
