In the first method, a C18 column whose temperature was kept constant at 25 °C was used. A combination of 0.1% formic acid solution in water and acetonitrile (50/50, v/v) was used as the mobile phase, and isocratic elution was performed at a flow rate of 1.0 mL min-1. Detection was carried out at 288 nm using the UV detector. Although all other conditions are the same as in the first method, the only difference in the second method is that ethanol is used instead of acetonitrile as the organic modifier in the mobile phase. HPLC methods were validated in accordance with ICH guidelines. Correlation coefficients were greater than 0.999 in the concentration range of 5-30 mg mL-1. Later, HPLC methods were applied to pharmaceutical formulations. Results were compared using the student (t) test for means and the Fischer (F) test for standard deviations. No significant differences were observed between methods. Additionally, a greenness evaluation of the developed methods was carried out using AGREE software. As a result, the latter method was proposed as an excellent eco-friendly alternative for the determination of torasemide in pharmaceuticals.

An aqueous electrolyte medium (6 M KOH) was used to investigate the electrochemical corrosion behaviour of Co3O4-coated plates. According to the Tafel plot, coating Zn plates with a high surface area and mesoporous Co3O4 in KOH electrolytes greatly reduced the corrosion of the plates. The coated plates are thermally treated up to 600℃. The temperature-dependent anticorrosive properties of Co3O4 NPs are evaluated.

In this study, sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice was investigated for bio-ethanol production. Most reports on bio-ethanol productions use commercial Saccharomyces cerevisiae as yeast. However, this study used finger millet (Eleusine coracana) malt with already high adaptation to local conditions and high economic viability as it is being utilized by the indigenous communities. Five sweet sorghum varieties of IESV-92001-DL (V1), NTJ (V2), 15233-IESV (V3), 92008-DJ (V4) and IESV-92028-DL (V5) were planted at 0°3'45.4644\" North, 34°17'16.1052\" South, in Kenya. °Brix content of juice was determined at 11th to 16th weeks after sowing. Highest °Brix for all varieties were at 15th week where V1 was highest at 22.07. V1 was then harvested for the juice. Factors affecting fermentation; temperature, time, pH and yeast to substrate ratio were optimized using Taguchi method and were obtained as 30 ℃, 48 hours, pH 5 and 5 g/L, respectively. Kinetics parameters of Vmax and Km were 0.35 g/L/h and 12.56 g/L, respectively. The optimized and kinetic parameters were within literature values and therefore finger millet malt has a great potential, as a substitute yeast source, in commercial bio-ethanol production.

In the synthesis of CLEO mediated AgNPs (CLEO-AgNPs), the one-factor-at-a-time method was used to optimize the reaction parameters. Ultraviolet-visible (UV-Vis) peak of CLEO-AgNPs was determined at 426 nm. Fourier transform-infrared (FTIR) spectra analysis identified the functional groups participating in the bio-reducing, capping, and stabilizing processes in the CLEO-AgNPs synthesis. Scanning electron microscope (SEM) image demonstrated the predominately spherical shape and the average size of 70.86+1.80 nm of CLEO-AgNPs. Energy dispersive X-ray spectroscopy (EDX) peak profile depicted the presence of Ag elements in CLEO-AgNPs. The X-ray diffraction (XRD) peaks observed at 38.5°, 44°, 65°, and 77° which represent Ag(111), Ag(200), Ag(220), and Ag(311) lattice faces, respectively. The average zeta nanosize, zeta potential, and polydispersity index of CLEO-AgNPs were determined as 69.70 nm, -43.5 mV, and 0.256, respectively. The stability test exhibited the prolonged storage stability of CLEO-AgNPs for over six months at room temperature. CLEO-AgNPs demonstrated the potential colorimetric detection of K+, Mg2+, Al3+, Cr6+, Mn2+, Fe3+, Ni2+, Cu2+, Zn2+, Hg2+, Pb2+, and Cd2+ ions in the real samples.

The results showed that the three samples were substantially comparable in terms of proximate compositions and physicochemical attributes. They have an acidic pH range and a very low fat content. In terms of phytochemical properties, Texenna green pods had the highest levels of polyphenols, flavonoids, and flavonols, with concentrations of 87.10 ± 0.07 μg GAE/mg DM, 4.90 ± 0.06 μg QE/mg DM, and 37.0 ± 0.19 μg QE/mg DM, respectively. Furthermore, the total antioxidant capacity of the methanolic extracts was determined using the phosphomolybdate method and found to be 154.62 µg AAE/mg DM.

This research presents the efficiency of surfactant-modified (SMNZ) and unmodified natural-zeolite (UNZ) in the immobilization of Cr3+, Pb2+, and Cd2+ in the soil system. Phillipsite is identified as a major component of the host zeolite. Soil mixed with 20% UNZ retained the highest amount of all metals on the top layer of the soil-zeolite column. The lowest transfer of metals into the maize crop was observed at 30 mg of UNZ/kg soil. The experimental conditions such as pH, dose, stirring speed, contact time, and initial metal ions concentration showed significant effect on adsorption of Cr3+, Pb2+, and Cd2+ onto both unmodified and modified zeolite (phillipsite). The maximum adsorption (mg/kg) onto control soil, soil mixed with SMNZ and UNZ was 67.1, 90.9, 151.5 for Cr3+, 84.8, 120.5, 238.1 for Pb2+, 83.3, 116.3 and 212.8 for Cd2+ respectively. Thus, the use of natural zeolite, particularly UNZ has an important role in controlling the mobility of Cr3+, Pb2+, and Cd2+ metal ions in the soil system and thus their transfer to plant system.
