Introduction Quantum dots (Q-Dots) is very small semiconductor particles that means it can be either conductors or resist electricity depending on the temperature and purity of the semiconductor. Q-dots range in size from 2-10 nm, so because of their small size, quantum mechanics governs the physics of the particles. The synthesis Q-Dots were first studied in 1982 by Efros and Ekimov, and then many developments have reported the synthesis of semiconductor nanoparticles.1 Q-Dots have unique…

Schizophrenia is a severe mental illness that affects human beings in varying degrees. It is a persistent and incapacitating brain ailment that has affected many people throughout the world.

Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…

CHAPTER 1 INTRODUCTION Since time immemorial microorganisms have played a significant role in the life of mankind owing to the production of the myriad enzymes and secondary compounds that they synthesize (Demain 1981). These micro organism live in a highly diverse environment ranging from hot springs to deep ocean sediments. In the hyper diverse environment where one can find a specialized and unique biological niche is the intracellular space between cells of higher plants acts as suite and…

Ebola virus disease (EVD) causes major illness in humans, which leads to death; this virus is the most lethal virus that has infected primates. The appeared originally in areas of Sudan and Zaire in the year of 1976. It is believed that the natural reservoir of the virus comes from fruit bats. Ebola is part of the Filoviridae family. The virus is mostly transmitted through direct contact with bodily fluids such as saliva and blood. Ebola can be difficult to detect in the beginning due to its…

Pollution is one of the most serious problems that affect our environment, and its effects on all life aspects are clear to everyone. Because of this, pollution is one of the most serious issues that all the word countries are concerned about. As time goes, the pollution problem increases and also the population growth increase. The increase in demand for water and food supplies place an increasing stress on the ground and surface water quality and quantity. One of the environmental problems…

Mixed contamination of PAHs and metals occur ubiquitously in the environment, but their combined toxicity to humans and other organisms are not fully addressed. The data from epidemiological, animal and in vitro studies indicated the nature of interaction between PAHs and metals varies from synergism to additivity or antagonism. In this chapter, the combined toxicity of PAHs and metals on toxicokinetic and toxicodynamic endpoints, and possible mechanism of actions were discussed. In addition,…
