Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...

The study presents photometric analysis of the completely eclipsing contact binary systems TYC 8351-1081-1 and ASAS J210406-0522.3. is an extremely low mass ratio (q=0.086) system with high degree (f=0.66) while J210406-0522.3 found to be in marginal (f=0.08) a relatively 0.272. There good thermal both only small difference temperature components. have been observed by number sky surveys over p...
