The emission spectra emitted from the laser-induced plasma of optical window Aditya Tokamak have been studied to identify eroded materials deposited on its surface. Different layers window, such as impurity layer, antireflection coating and main matrix material, identified. Laser-induced breakdown spectroscopy (LIBS) layer (first layer) shows presence spectral lines Fe, Cr, Ni, Mn, Mo, Cu, C O most which are components stainless steel (SS316L) used for fabrication Tokamak. LIBS (second show...
Few-layer MoS2 films stay at the forefront of current research two-dimensional materials. At present, continuous are prepared by chemical vapor deposition (CVD) techniques. Herein, we present a cost-effective fabrication large-area spatially uniform few-layer flakes using modified Langmuir-Schaefer technique. The compression liquid-phase exfoliated on water subphase was used to form layer, which subsequently transferred onto submerged substrate removing subphase. After vacuum annealing,...
In the present manuscript, we demonstrate design of an experimental setup for on-line laser induced breakdown spectroscopy (LIBS) analysis impurity layers deposited on specimens interest fusion technology, namely, plasma-facing components (PFCs) a tokamak. For investigation impurities PFCs, LIBS spectra tokamak wall material like stainless steel sample (SS304) have been recorded through contaminated and cleaned optical windows. To address problem identification dust gases inside tokamak,...
Abstract The growth of the pharmaceutical industry to keep pace with well-being humans worldwide has posed many challenges related quality control. This paper reports on potential application a modern optical spectroscopic technique popularly known as laser-induced breakdown spectroscopy (LIBS) address some aspects such sample constituents, hardness, and classification five different samples. surface analysis these samples been carried out using microscopy (OM) atomic force (AFM). LIBS...
This study describes the effect of ultrasonic pretreatment on bioethanol, bio-methanol, methane and VFAs production from dairy wastewater pretreated rice straw (RS). The was carried out in eight batch reactors with inoculum derived cow dung soil separately (four for each soil). These were fed DWW RS followed by bath 5, 10 15 minutes three separate fourth reactor set up without pretreatment. Maximum yields 303.2 L/kgRS (for untreated reactor) 151.62 min. ultrasonication) dung, respectively....
