ZnO Nanostructure Shape Effects in Photocatalysis of Methylene Blue
Abstract: Nowadays, dyes are used in the food industry, textile industry, paper industry, hair coloring, light-harvesting arrays, photoelectrochemical cells, etc. Most of the dyes are nonbiodegradable, toxic, carcinogenic, and consist of organic compounds. These dye wastages are discharged into water bodies and the environment causing serious hazards to the marine ecosystem as well as the humans extensively. To treat toxic dyes traditional methods such as adsorption, activated carbon, ultrafiltration, and reverse …

Enhancement of Gas Sensitivity of Composites of Carbon Derived from Rubber Tree and SnO2 to Detect Ethanol Vapor at Room Temperature
Abstract: Films of composites of activated carbon powder prepared from saw dust derived from core of rubber tree (Hevea Brasiliensis) and tin oxide (SnO2) were fabricated using the doctor blade method. Carbon powder was activated using phosphoric acid at 500°C for 45 minutes. The weight ratio carbon/SnO2 varied from 0 to 12% in steps of 2. The structural, optical and morphological properties of films were investigated using XRD patterns, UV-visible spectrums …

Eu3+/Gd3+ doubly doped ions in SrCO3-Al2O3-B2O3-SiO2 glasses for optical and White light applications
Abstract: The present work deals with the optical analysis of SrCO3-Al2O3-B2O3-SiO2 glass materials doubly doped with Eu3+/Gd3+ ion were prepared by melt quenching technique. These are studied by XRD, physical properties, FITIR, optical absorption and luminescence spectroscopy. The XRD measurements are conducted to verify the amorphous form of prepared material and structural modifications can be explained by the FTIR spectra. The thermal stability of the glass matrix is measured by the …

Study of pH Behaviour of Slurry on Surface Morphology of Copper Material with Single Pole Magnetic Abrasive Finishing Process
Abstract: The chemical oxidizers—sodium hydroxide, Marshall’s acid salt, and hydrogen peroxide—were effectively employed in the wet polishing of copper using the SPMAF experimental setup. The manuscript explores preparation of slurry used for polishing copper material using single pole magnetic abrasive finishing (SPMAF) framework. The slurry contains distilled water, 1200-grit aluminum oxide abrasives, sodium hydroxide (NaOH), potassium persulfate (K₂S₂O₈), and hydrogen peroxide (H₂O₂), combined in precise amount. Specifically, 100 ml of distilled …

Effectiveness of a Video-based Teaching Program on Knowledge and Attitudes Toward Stem Cell Therapy Among Nursing Students
Abstract: Integrating stem cell therapy (SCT) into healthcare necessitates adequate training for nursing students to comprehend its principles and applications. This study evaluates the efficacy of a video-assisted teaching program (VATP) in enhancing knowledge and attitudes toward SCT among nursing students. A pre-test post-test quasi-experimental design was utilized with a sample of 100 nursing students. The participants were split into experimental and control groups. The experimental group received the VATP intervention, …

Study of Binary Systems Based on Butadiene-Terephthalate Rubber and Astragals and Its Rheological Properties
Abstract: Study of binary systems based on butadiene-terephthalate rubber and Astragals and it In this work, Nano sized astragals was used for the first time to modify butadiene terephthalate rubber. For this purpose, compositions were prepared to study the properties of butadiene terephthalate rubber with different astragals contents of 1, 3 and 5 mass parts. Their results were compared with the control composition without nanoparticles. The presence of astragals and its …
