This manuscript reports on the physical properties and optical band gap of five samples soda lime silicate (SLS) glass combined with zinc oxide (ZnO) that were prepared by a melting quenching process. To understand role ZnO in this structure, density, molar volume gaps investigated. The density absorption spectra Ultra-Violet-Visible (UV-Visible) region recorded at room temperature. results show densities increased as weight percentage increased. glasses shows same trend density: content...
Three novel natural amino acid-derived sodium L-2-(1-imidazolyl) alkanoic acids (IZSs), namely, 2-(1H-imidazol-1-yl)-4-methylpentanoate (IZS-L), 2-(1H-imidazol-1-yl)-3-phenylpropanoate (IZS-P), and 2-(1H-imidazol-1-yl)-4-(methylthio)butanoate (IZS-M), were investigated as corrosion inhibitors. The IZSs synthesized following the green chemistry principles, their structure was characterized using FTIR NMR techniques. study results reveal that a moderate concentration of (having low solution...
The effects of ZnO on longitudinal and transverse ultrasonic wave velocities soda lime silicate (SLS) glasses have been measured using the pulse-echo method at 5 MHz frequency room temperature. elastic properties: Longitudinal modulus, shear Young’s bulk Poisson’s ratio, Debye temperature are found to be rather sensitive glass composition. Experiments showed that these parameters depend upon ZnO-modifier content. Key words: Glasses, annealing, measurements, properties.
The increasing awareness of people on green materials and chemistry has stimulated researchers around the globe to turn towards natural resources. As a growing topic with limitless potential, plants as corrosion inhibitors (PCI) have received substantial attention due their eco-friendly, biodegradable, inexpensive, abundantly available. Therefore, understanding importance this topic, study is conducted in format descriptive systematic literature review (SLR) assess global research trends PCI...
High demands on low-voltage electronics have increased the need for zinc oxide (ZnO) varistors with fast response, highly non-linear current-voltage characteristics and energy absorption capabilities at low breakdown voltage. However, trade-off between voltage grain size poses a critical bottle-neck in production of varistors. The present study highlights synthesis mechanism obtaining praseodymium (Pr(6)O(11)) based ZnO varistor ceramics having voltages 2.8 to 13.3 V/mm through employment...
Metallic materials are the most applicable in various industries.They useful due to their excellent mechanical properties.However, they exposed corrosion because environment contains oxygen, humidity and some other factors.This paper describes about a paint incorporated with organic inhibitor, i.e., henna extract.This was produced enhance its anticorrosive property.Henna extract chosen as inhibitor it is organic, environmentally acceptable, readily available renewable source of material for...
With the trend for green technology, study focused on utilizing a forgotten herb to produce an eco-friendly coating. Andrographis paniculata or kalmegh leaves extract (KLE) has been investigated its abilities in retarding corrosion process due excellent anti-oxidative and antimicrobial properties. Here, KLE was employed as novel additive coatings formulations were made by varying wt%: 0, 3, 6, 9, 12. These applied stainless steel 316L immersed seawater up 50 days. The samples characterized...
