    Effect of dual flocculant by unmodified manihot esculenta starch and aluminium sulphate on the removal of chemical oxygen demand optimized by response surface methodology by Rahmat, S., Othman, N, Ahmad, S. N., Asharuddin, S. M.

    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. …”

    Novel miniature microwave quasi-elliptical function bandpass filters with wideband harmonic suppression by Riaz, Muhammad

    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 by Saleh Mubarak, Salah

    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. …”
