Fabrication of Porous Co3O4 Arrays by a Co-Precipitation Method and it Application as a Non-Enzymatic Glucose Sensor

The porous cobaltosic oxide (Co3O4) arrays has been prepared by a chemical co-precipitation route using the nickel foam as s substrate. Cyclic voltammetry (CV), and ampere current method (i-t curve) are used to explore the non-enzymatic glucose sensor in a three-electrode system. This porous Co3O4 array non-enzymatic sensor shows a sensitivity of 592.8 mA mM1 cm2 in concentration from 0.99 M to 1.073 mM. The porous Co3O4 array sensor electrode also showed low LOD value (0.005 M) and fast response time (4 s). This porous Co3O4 electrode shows a good sensor performance due to these rich more

Removal of Food Dye Tartrazine (E102) from Aqueous Solution using ZnO and CuO-TiO2 as Photocatalysts

Tartrazine dye has a major role in food as well as in other industrial products, like cosmetics, personal care products, pharmaceutical products and many more, therefore it is the cause of many environmental pollutions particularly water pollution. Its removal from water bodies is almost impossible with traditional techniques, because of heterogeneity in its composition. This investigation was carried out to examine the photo-catalytic degradation of food dye tartrazine (E102) from its aqueous solution, using ZnO (zinc oxide) and mixed CuO-TiO2 (copper oxide-titanium dioxide) as more

Native Biofilm Used in Mediated Method for Toxicity Measurement

A native biofilm (NBF) bioreactor for monitoring total toxicity in water was developed in this article. Specific objectives include the investigation of (i) the NBF was introduced in toxicity measurement, and (ii) the immobilized microorganisms on carbon fiber felts are adopted for mediator toxicity assay. Culture conditions of NBF with 35 ◦C and 24 h were adopted, and a measuring condition with 45 mM ferricyanide (at pH 7) was optimized. Under the above conditions, NBF bioreactor was successfully employed to assess toxicities of four toxicants. By adopting the NBF, the IC50 values obtained more

Synthesis of New Series of Transition Metal Complexes with Poly (Pyrazolyl) Borates

In structuring catalysis enzyme and chemistry, tridentate ligands and Scorpionate ligands are of significant worth. This study presents the synthesis of a tris(pyrazolyl)borate ligand to be utilized in transition metal complexes as possible redox shuttles. Complexes of general formula [AgTp], [MIIITp (Cl2)] (M = Fe, Co), Tp = tri (1-pyrazolyl) borohydride and [AgTp*], [FeIIITp*(Cl2)], Tp* = tris (3, 5-dimethyl-1-pyrazolyl) borohydride were synthesized and characterized in solid state. The Tp ligands were considered triply coordinated with the metal center with two bounded chloride atoms as more

Photocatalytic Degradation of Malachite Green Dye with UV/H2O2 System in presence of Transition Metal Ions

The chemical degradation of Malachite Green dye has been studied by using UV/H2O2 system in presence of transition metal ions (Fe2+, Mn2+ and Ti2+). The degradation reaction was carried out by circulating the aqueous dye solution in a custom-made UV reactor with the help of a variable speed peristaltic pump. The effects of initial concentration of dye, concentration of Hydrogen peroxide, operating temperature, pH, Ultrasound vibrations and transition metal ions were investigated on the time required for complete degradation of the dye. It has been found that under optimum conditions the dye more

GC-MS Analysis and Biological Effects of Essential Oil from Trachyspermum ammi L

Trachyspermum ammi L, local seed’s essential oil and its crude methanolic extract were evaluated for antioxidant, antibacterial, and urease inhibition activities. Largely, 18 constituents were identified in the essential oil using The GC-MS. The promising constituent reported was terpeniodes; which seem to be responsible for the reported biological activities. DPPH Free radica1 scavenging assay was done to evaluate the antioxidant activities of both oil and crude extract. The DPPH scavenging activity results in lC50 values of 75 ± 0.05 and 300 ± 0.03. Antibacterial activity of the oil was more

Study the Effect of Zwitterionic Hydrophilic Interaction for Simultaneous Determination of Non-Steroidal Anti-Inflammatory Drugs in Dosage Forms

Flurbiprofen and ketorolac are non-steroidal anti-inflammatory drugs (NSAIDs) that include both hydrophilic and hydrophobic functional groups in their structures. By connecting sulfobetaine molecules to polystyrene-divinylbenzene particles, two ZIC-HILIC stationary phases (ZIC-SB1 and ZIC-SB4) were developed for chromatographic separation of NSAIDs with varying chain lengths using Ultraviolet as detection. The different chain lengths of the stationary phases are utilized to investigate the retention behaviour of NSAIDs. Simultaneous quantification methods for ZIC-HILIC were developed. more

Synthesis, Spectroscopic Analysis, Biological Evaluation, and In Silico Studies of Novel Benzenesulfonate-Derived Schiff-Mannich Bases

In the current study, 3-formyl phenyl benzenesulfonate is created by reacting 3-hydroxybenzaldehyde with benzene sulfonyl chloride, which is aided by triethylamine. Nine unique (Z)-3-[(3-substituted-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl)-iminomethyl] compounds were formed through the reaction of a manufactured 3-formyl phenyl benzenesulfonate chemical with nine 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-one, as detailed in the existing literature. Phenyl benzene sulfonate (S) compounds were purchased. Through the reaction of the Schiff bases that were made a secondary amine, such more
