Gold nanoparticle (GNP) immobilised optical fiber sensors have been explored extensively in the last few decades. These combine intrinsic refractive index (RI) sensitivity of and localised surface plasmon resonance (LSPR) effect GNP to provide a high sensing response. On other hand, titanium dioxide (TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) thin film coating had drawn enormous attention due its RI, anti-corrosive nature...
The typical phenomena of mixed mode oscillations and their associated nonlinear behaviors have been investigated in collisionless magnetized plasma a DC glow discharge system. Plasma is produced between cylindrical mesh grid constricted anode. A spherical 80% optical transparency kept inside to produce an inverted fireball. Three Langmuir probes are the ambient measure floating potential fluctuations at different positions chamber. It has observed that under certain conditions voltages...
: In this study, naturally occurring clay halloysite has been used to synthesize novel functionalized sulfonic acid in two steps, i.e. functionalization followed by oxidation, and its catalytic activity estimated for one-pot synthesis of Hantzsch 1,4-dihydropyridines under green solventfree conditions. Spectroscopic studies such as FTIR, TGA, elemental analysis first-principles-based quantum chemical have employed characterize the catalyst. Recyclability without significant loss observed...
A D.C. glow discharge plasma source was employed to characterize changes in water absorbance and surface morphology of natural jute fibers. The low temperature removed moisture from the fibers significantly modified properties. Scanning electron microscopy energy dispersive X-ray spectroscopy were used for characterization. Open software processing scanning micrographs. macromolecular structure crystallinity characterized by diffraction. Thermogravimetric analysis demonstrated removal...
Oscillating plasma bubbles have been created around a cylindrical mesh grid of 75% optical transparency in DC system with low magnetic field. Plasma are by developing ion density gradient 20 cm diameter and 25 height, inserted into the plasma. Relaxation contraction presence external conditions, such as field pressure, studied. A Langmuir probe has used to detect floating potential fluctuations at different imposed experimental conditions. Nonlinear behavior characterized adopting nonlinear...
Water hyacinth [Eichhornia crassipes] is a widely available natural fiber and used in many applications recent years. Eco friendly plasma sputtering technique has been employed to get Copper (Cu) coat on fibers. The effects of working pressure, power time have considered optimize the best possible output Cu coated Functional group uncoated fibers analyzed by XRD ATR-FTIR. Surface morphology Scanning Electron Microscope hydrophobic nature measured Contact Angle measurement. antibacterial...
Experimental evidence of different kinds oscillations in floating potential fluctuations glow discharge magnetized plasma is being reported. A spherical gridded cage inserted into the ambient volume for creating bubbles. Plasma produced between a mesh grid and chamber. The 80% optical transparency connected to positive terminal power supply considered as anode. Two Langmuir probes are kept measure positions within system, viz., inside outside grid. At certain conditions voltage (Vd) magnetic...
Background:The coronavirus disease-2019 (COVID-19) pandemic has brought about a change in healthcare practices that are likely to persist into the foreseeable future.In particular, is exposure risk practitioners emergency department (ED) and intensive care units.Mitigating this issue low-resource setting remains challenging, developing nations such as India, where ED patient flows can overwhelm system its human resources, breaking down processes infecting workers (HCWs).Technique: To tackle...
