Zero Trust Architecture, Ahmed Abdullah Syed Jan 2022

Zero Trust Architecture, Ahmed Abdullah Syed

All Student Theses

Cyber threats are becoming increasingly sophisticated, and IT organizations need to continue to modernize their approaches to cybersecurity in light of today's dynamic cyber threat environment. Cybersecurity professionals must adopt a zero-trust security model and the mindset needed to engineer and operate a system specifically designed to operate according to zero trust principles in order to ensure the security of sensitive data, systems, and services as enterprise networks become increasingly dispersed and complex.


Bond Valence Sum Analysis On Compounds Prepared By Topochemical Manipulation, Yasmin Dayeh Jan 2022

Bond Valence Sum Analysis On Compounds Prepared By Topochemical Manipulation, Yasmin Dayeh

All Capstone Projects

The Bond Valence theory of Brown (1978) has been extensively used to correlate metal oxidation state to coordination environment in solids. Although the bond valence sum (BVS) appears to be extremely useful to coordination chemists, it has not often been applied as an alternative measure of refinement quality. In this work, previously reported six layered perovskite compounds including, RbLaNb2O7, Rb2LaNb2O7, Rb2SxLaNb2O7 (x ≤ 0.8), NaLaNb2O7, (Cs2Cl)LaNb2O7, and (FeCl)LaNb2O7, that have been prepared by topochemical manipulation and their structures have been determined by Rietveld refinements were analyzed. Our focus was to explore whether the determination of oxidation state using the bond …
