Mathematical models of the response of populations of microorganisms exposed to ultraviolet germicidal irradiation (UVGI) are developed that include two-stage response curves and shoulder effects. Models are used to develop a C++ computer program that is capable of predicting th…

The consumption of unsafe fresh vegetables has been linked to an increasing number of outbreaks of human infections. In Lebanon, although raw vegetables are major constituents of the national cuisine, studies on the safety of fresh produce are scant. This research employed a hol…

Heterogeneous photocatalysis has attracted a large number of researchers around the globe due to its intriguing advantages in the area of environmental remediation. The ability to degrade numerous pollutants and disinfect microorganisms using an inexpensive catalyst and low ener…

Photocatalytic oxidation is a process in which a semiconductor upon adsorption of a photon acts as a catalyst in producing reactive radicals, mainly •OH radicals, which in turn can oxidize contaminant species. These •OH radicals completely mineralize even the dead microbial spec…

The goal of this project was to prepare a user-friendly document that addresses concerns with regards to cleaning and disinfecting, and offers up a potential alternative to traditional products. The research starts with the history and mechanism of action of bleach, builds upon …
