Host Ba2MgSi2O7 phosphor was successfully prepared via low temperature combustion synthesis route. The phase identification of the done with help powder XRD technique. pattern revealed its monoclinic crystal symmetry a space group C2/c. have well clarified JCPDS PDF card no. #23-0842. average crystallite size calculated as 42nm and lattice strain 0.24, respectively. It is acquired that sample U...
In glow discharge optical emission spectrometry, two-dimensional emission images for iron atomic lines were measured by using an imaging spectrograph equipped with a CCD detector, when a radio-frequency (r.f.) power source was employed for excitation. Emission images at the Fe I 371.99-nm and the Fe I 375.82-nm lines, having different excitation energies, were analyzed by the two-line method to...
This work is aimed at investigating the influence of the inter-electrode spacing on the production rate and size of nanoparticles generated by evaporating a cathode on an atmospheric pressure dc glow discharge. Experiments are conducted in the configuration of two vertically aligned cylindrical electrodes in upward coaxial flow with copper as a consumable cathode and nitrogen as a carrier gas. ...
HCCI operating window has two distinct boundaries of knock at higher load region and misfiring/partial burning at lower load region. Moreover, there is no conventional direct way of controlling combustion timing in an HCCI engine. In this research, experimental study were carried out to investigate the effect of thermal and charge stratification on expansion of the operating range of a natural ...
