In this research, fibers were obtained by adding hazelnut shell powders which are a natural filler material (HSP) at different concentrations into Poly (lactic acid) (PLA) by using the electrospinning method, which is the most common method to obtain fibers. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), tensile strength measurement, and physical analysis such as density, surface tension, viscosity, electrical conductivity test was performed after the fiber production process. The results obtained from this study, fibers showed beadles and smooth surfaces. ..read more

Cotton being easily available, low cost and highly porous natural material is excellent candidate as adsorbent base. However, its super hydrophilicity hinders its applications as oleophilic adsorbent. In the present study, pristine cotton was impregnated with ZnO and stearic acid to provide it with rough surface and hydrophobic properties followed by dip coating of polystyrene for further enhancement of its oil adsorption capacity. The surface morphology of polystyrene coated ZnO impregnated non-woven cotton (PS@ZnO-NWCotton) and polystyrene coated ZnO impregnated woven cotton (PS@ZnO-WCotton)..read more

Titanium dioxide is also called titania and occurs in nature in anatase and rutile forms. It is widely used as a white pigment, catalyst support, and photocatalyst. Nano-TiO2 pigments in pure crystallographic anatase phases have been successfully synthesized via sol-gel method. Nano-TiO2 material has been characterized by various techniques such as XRD, TEM, and XPS. The prepared nano-TiO2 was mixed with two different offset inks (falcon and jobbing) to upgrade the physical and optical properties of the offset inks and compared with Degussa TiO2 before and after the application was tracking an..read more

This manuscript has reported the micellar interaction of cationic triphenylmethane-based dye "Victoria Blue-B (VBB)". The study was conducted using ionic surfactants viz. Cetyltrimethylammonium Bromide (CTAB)] Sodium Dodecyl Sulphate (SDS), and Sodium Docusate (SD). The behavior of dye in micellar media at concentration ranges of the surfactants mentioned above was monitored by UV-vis absorption spectroscopic study. The solubilization parameters to reveal the interaction of cationic dye in micellar media were assessed. The mathematical calculations of partition constant (Kc), partition coeffic..read more

FeSe-WSe2 composite photocatalyst was synthesized by a facile one-pot hydrothermal reaction with WSe2, sodium selenite (Na2SeO3), hydrazine hydrate (N2H4·H2O), hydrochloric acid (HCl), and Ferric chloride (FeCl3). Different ratios of FeSe-WSe2 composite photocatalysts were synthesized according to different Fe content, and FeSe-WSe2 was characterized by XRD, SEM, UV-vis DRS and XPS. At the same time, the photocatalytic performance and catalytic mechanism of the composite photocatalyst were explored through the degradation of methylene blue (MB) by the composite. The experimental results show t..read more

During the past decade, significant progress has been made in synthesizing various nano-based products for industrial application. Among them, magnetic Fe3O4/layered double hydroxides nanocomposite materials have attracted broader applicability. The uniqueness of these nano hybrid nanocomposites have attracted valuable utility to nanotechnology field due to their magnetic properties and enhanced catalytic performance compared to layered double hydroxides (LDHs). The electrostatic interaction between positively charged LDHs and negatively charged Fe3O4 makes them more stable. Therefore, the pre..read more

A simple calcination process was used to create g-C3N4 (CN) from melamine, and the modified g-C3N4 (MCN) was synthesized with hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). After acid modification, CN successfully introduced oxygen-containing functional groups and obtained CN-HNO3 with multiple holes, which improved the photocatalytic efficiency. The bandgap of CN-HNO3 (2.46 eV) is 0.24 eV lower than that of CN (2.70 eV), resulting in more electron holes and improved light absorption of the catalyst. CN-HNO3 has a conduction band (CB) of -1.23 eV, while CN has a CB of ..read more

Four different prodrugs were prepared by linking various antibiotic drugs (Ampicillin, Amoxicillin, Ceftriaxone, and Cefotaxime) with 4-maleimidobenzoic (4-(2,5-dihydro-1H-pyrrol-1-yl)benzoic acid), which is firstly converted to 4-(2,5-dihydro-1H-pyrrol-1-yl)benzoyl chloride in the presence of SOCl2 to form four maleimide derivatives [5a-d]. These derivatives were characterized by FT-IR, 1H NMR, 13CNMR, and C.H.N.S. and then studied for their antibacterial activity against E. coli and S. aureus bacteria. As well as studied the anti-cancer activities and determined their potential to reduce cel..read more
