Direct Conversion of Dry Algae to Biodiesel under Supercritical Methanolysis: An Advanced Research

The goal of the research is to convert dry algal biomass into biodiesel in a single step under supercritical methanol conditions, which is both environmentally benign and cost effective. Methanol is used to extract and transesterify lipids from algae under supercritical conditions, resulting in fatty acid methyl esters. The fatty acid methyl esters are generated […]

Determining the Physicochemical Parameters of Soil and Groundwater in Kaltungo LGA, Gombe State, Nigeria

Groundwater and soil samples were collected in Kaltungo LGA, Gombe State, in April 2012 to determine the quality of the groundwater (dry season). The purpose of this research was to look at various physicochemical parameters of drinking water samples collected from hand-dug wells and boreholes that had not been treated before use. The purpose was […]

Use and Efficiency of Alginic Acid to Remove Some Heavy Elements from Pollutant Water

Heavy metals (Pb, Cr, Co, and Fe) were removed from polluted water in this study utilising a chemical approach that included the inclusion of a biological polymer (alginic acid). Different concentrations (0.5,1,1.50,2 ppm) were present for each element. The pH 5 and duration of the test were assessed after 72 hours, and the leftover amounts […]

Mechanical Properties of Composite Material Based on Polypropylene and Vietnamese Rice Husk Filler: Experimental Investigation

The development of novel materials combining polymers and renewable resources has resulted from consideration of the environmental impact of polymer goods today. Biocomposites have received a lot of attention among these materials. The goal of this study was to create biocomposites made of polypropylene and Vietnamese rice husk flour with a limited size distribution (100–125 […]

Effect of pH on Benzoic Acid Solubilization and Its Partition in Water-Benzene Solvents

The solubility of a substance is determined by the solute-solvent interaction, pH, temperature, and ionic dissociation, among other factors, where the solute is partitioned between two immiscible liquid solvents. The solubility of benzoic acid (solute) as well as its partitioning between hydrophilic water and hydrophobic benzene, which are utilised as solvents at room temperature (25°C), […]

Determination of Lactic Acid Content during Embryonic Development of the Silkworm under Imposed Photoperiodic Regimes

When comparing the untreated control to the fluctuations in the lactic acid concentration of developing eggs during the day to day developmental phase, significant adjustments and favourable responses to light induction were identified. Lactic acid deposition during embryonic development in anaerobic environments is an adaptive approach for coping with the unfavourable environmental conditions. The current […]

Design, Synthesis, and Anti-Tubercular Studies of 10-(phenylsulfonyl)pyrimido[1,2-a]benzimidazol (10H) One Derivatives

Sulfonamides are a special class of chemicals with outstanding antibacterial properties. Sulpha medicines were the first efficient chemotherapeutic agents used to treat bacterial infections in humans, and they were shown to be resistant to Mycobacterium tuberculosis, Typhoid and Paratyphoid bacilli, and other germs. N-sulfonation of 2-substituted-pyrimido[1,2- a]benzimidazol-4(10H)-ones yielded a series of new 10-phenylsulfonyl-2-substituted-4,10 dihydrobenzo[4,5]imidazo[1,2- a]pyrimidin-4-one […]

Development of High Performance Liquid Chromatographic Determination of Ambroxol, Roxithromycin and Serratiopeptidase in Combined Tablet Dosage Forms

The researchers devised and validated a simple, sensitive, and accurate RP-HPLC technique for the simultaneous measurement of ambroxol, roxithromycin, and serratiopeptidase in bulk and combination tablet dose form. Using a Waters HPLC system with a YMC Pack pro C18 (250 4.6 mm, 5 m particle size) column, ambroxol, roxithromycin, and serratiopeptidase were separated and quantified. […]

Study on the Effect of Oxygenated Fuels on Emissions Characteristics: A Comparative Study between Compression Ignition and Spark Ignition Engines

Petroleum consumption is commonly regarded as one of the most significant factors to environmental degradation. The combustion of oxygenated fuel blends in diesel and gasoline engines is explored in this study, with a special focus on emissions. The study had two objectives: first, to identify the extent to which NOx, uHC, and CO emissions are […]

Glycoconjugates Study in Surface Secretions of a Fresh Water Edible Catfish, Clarias gariepinus in Response to Clove Oil Anaesthesia: Experimental Investigation

This histopathology and histochemistry study looks at the effects of clove oil anaesthesia on the gills, dendritic organs, and skin of Clarias gariepinus, a locally available fresh water edible catfish. Clove oil has long been known for its medical properties, and it was/is extensively used as an analgesic and antiseptic. Surface organs in C. gariepinus […]
