Thesis Abstract

Summary        In the present study, a newly exposure technique of radon gas (29055±691 Bq/m3) has been fabricated to study the effects of radon inhalation in the male albino rats. Seventy two rats had been used, which were housed under standard laboratory conditions (12 h light: 12 h dark of photoperiod), 22±4 ºC temperature) and were given standard […]

Summary Part I          The objective of this part is to synthesize zeolites from low cost locally available silicon sources. These materials will have great potential as catalyst, ion-exchange and adsorbent. This is the first extensive study that has been conducted in the synthesis of zeolite in Kurdistan region of Iraq. Suitable silica sources for

Abstract This study focuses on the architecture modification of solution-processed methylammonium lead iodide ((CH3NH3)PbI3)-based planar perovskite solar cells. The modification is obtained through a facile and cheap step formation at low temperature (<100 °C) using a simple inexpensive spin-coating technique. (CH3NH3)PbI3, as a light harvesting layer, was sandwiched between zinc oxide nanoparticle (ZnO-NP) thin film as a selective electron transport
