A UV laser ablation microprobe coupled to an ICPMS has been used determine trace element concentrations in solids with a spatial resolution of 50 microns and detection limits ranging from 2 μg/g for Ni ng/g the REE, The, U. Experiments designed optimize operating conditions show that pulse rates 4 Hz produce steady state signal less inter‐element fractionation per unit time than higher (10–20 Hz). Comparisons analyses garnets pyroxenes using NIST 610 612 glasses as calibration standards,...
Three-wheeled vehicles may be a better choice as compared with four-wheeler cars provided they are properly designed to improve the rollover stabilities and ride comfort. The design modifications need improvement in geometry suspension. This article presents dynamic behavior of three-wheeled vehicle equipped an inerter-based absorber compares same conventional suspension system. performance parameters analyzed vertical-lateral acceleration, front & rear deflection, tyre loads. analytical...
Background Axshya SAMVAD is an active tuberculosis (TB) case finding (ACF) strategy under project (Axshya meaning 'free of TB' and 'conversation') among marginalized vulnerable populations in 285 districts India. Objectives To compare patient characteristics, health seeking, delays diagnosis treatment initiation new sputum smear positive TB patients detected through ACF passive (PCF) the national programme between March 2016 February 2017. Methods This observational analytic study was...
There is limited evidence on whether active case finding (ACF) among marginalised and vulnerable populations mitigates the financial burden during tuberculosis (TB) diagnosis.To determine effect of ACF prevalence inequity catastrophic costs due to TB diagnosis TB-affected households when compared with passive (PCF).In 18 randomly sampled districts in India, March 2016 February 2017, we enrolled all new sputum-smear-positive patients detected through an equal number selected PCF. Direct...
Lattice oxygen participation is believed to be crucial for enhanced electrocatalytic evolution reaction activity of perovskite oxides. However, the inherent criteria uplifted O 2p-band lattice participation...
Abstract Magnesium alloy of grade AZ91D is utilized for a variety applications in aircraft design and frames, as well vehicle engine radiators, bumpers, suspension components to reduce the weight automobiles. This research compared mechanical, corrosion, wear, erosion resistance pure Mg that AZ91 alloy. The corrosion media was NaCl, NaOH, MgSO4, loss method utilised evaluate corrosion. pin-on-disc configuration assess dry sliding wear mechanism Pure monolithic magnesium have low result an...
We report on the effect of transverse magnetic field laser ablation copper and aluminum targets both experimentally numerically. The depth is found to increase with from 0 0.3 T decreases at a higher (0.5 T). It demonstrated that nanosecond mainly due melt ejection it solely depends thermo-physical parameters material. in attributed heat transfer plasma target, vapor pressure, shock pressure. also calculated using pressure through simulation compared measured depth. In presence field, we...
We report on the spatially resolved optical emission spectroscopic study of laser-produced copper plasma in presence static uniform magnetic field air ambient at atmospheric pressure. The response atomic/ionic lines to along axial direction is different. It attributed difference populating process (electron impact excitation and recombination) each transition. In present work, we introduced pressure calculate stopping radius found it be around distance which intensity pronounced. electron...
Formation of insufficiently oxidized Cu nanoparticles by laser ablation in organic solvents is correlated with the target surface.
Time-domain or transient dynamic response method is the most traditional used to evaluate of a vibratory system subjected deterministic inputs. The inertia damping effects are very crucial in time scale loading. present work determines domain analysis railway locomotive using finite element for Indian tracks. track inputs modelled as an ellipsoidal bump, and variations displacement at different key locations truck carbody models plotted standard loading conditions. plot front rear indicate...
We report on the pulsed laser ablation of aluminum (Al) plasma in presence ambient nitrogen to understand formation nitride (AlN). Formation carbon (CN) and titanium oxide (TiO) by laser-ablation graphite targets oxygen is also compared. discuss dynamics expansion based existing models, shock drag gas interface distortion, Rayleigh-Taylor instability at various pressures nitrogen. Since may give rise self-generated magnetic field plasma, an attempt made mechanism generation as well...
We report on the pulsed laser ablation of aluminum in presence nitrogen gas using a 1.06 μm wavelength Nd:YAG laser. A prominent band nitride corresponding to (0-0) system belonging π3−π3 transition was observed at 507.8 nm. An attempt is made identify ionized states and contributing formation AlN band. films were deposited room temperature characterized x-ray diffraction. direct correlation between ablated plasma film reported.
In the present work, MoS2 quantum dots (QDs) were synthesized by chemical-free, single step photo-exfoliation of a solid target using pulsed laser ablation in distilled water. with average sizes ∼4, 2.9, and 6.1 nm ablating an for durations 5, 10, 20 min at fixed energy 40 mJ.
