Compiler and Machine Learning-based Predictive Techniques for Security Enhancement through Software Debloating
… has become one of the prime focuses of attack surface reduction research. The aim is to break these chains of gadgets, thereby making such code reuse attacks impossible or substantially less common. Recent work on attack surface reduction has attempted to eliminate these attacks by subsetting …

Ion Beam Synthesis and Irradiation for Si-Based Photonic Materials and Nuclear Waste Management
… increased the fraction of U in the U(IV) state (surface reduction), while aqueous conditions promoted surface oxidation, with increased U(VI) compared to unirradiated UO₂. These findings suggest that prolonged exposure of used fuel to residual alpha radiation within a sealed used fuel container …

Geometric and Electronic Structure Sensitivity of Methyl and Methylene Reactions on α-Cr₂O₃ and α-Fe₂O₃ surfaces
… on three different oxide single crystal surfaces: α-Cr₂O₃(101̅2), α-Cr₂O₃(0001), and α-Fe₂O₃(101̅2). The intermediates have been generated through the decomposition of halogenated hydrocarbons. The primary reactions of methyl and methylene over α-Cr₂O₃ are methyl dehydrogenation to …

Combining Experiments and First-Principles Calculations to Understand and Engineer Metal Exsolution in Perovskites
… In exsolution, metal cations are exsolved to the surface of a perovskite oxide solid solution under reducing conditions. The result is a perovskite backbone decorated with partially embedded metallic nanoparticles. The stability and anti-coking properties of exsolved nanoparticles have driven …

Synthesis of anion exchange/activated carbon fiber hybrid materials for aqueous adsorption of toxic hexavalent chromium
… not only very high mesopore content with a surface area up to 1085 m2/g based on coating, but also good strong base ion exchange capacity up to 1.5 meq/gC and exceptionally fast kinetics due to multi-scale facilitated mass transfer. Compared with conventional activated carbon and ion …

DynaCut: A Framework for Dynamic Code Customization
… memory but also in an increase in their attack surface. Existing works broadly use binary-rewriting techniques to remove unused code, but this results in a binary that is highly customized for a given usage context. If the usage scenario of the binary changes, the binary has to be regenerated. …

THE EFFECT OF ALTERNATING DISTRIBUTION OF TRANSITION METALS IN LAYERED MATERIALS ON OXYGEN EVOLUTION CATALYSIS
… chapter 3 we present a study of the effect of surface reduction of birnessite on catalytic activity. A sample of birnessite was reduced by stirring with sodium dithionite, in which case the oxidation states of surface Mn decreased faster than those of inside Mn. We characterized the difference …
