Probing the electrochemical dynamics of soluble redox active polymers
… into a nanostructure, they give rise to charge transfer mechanisms and electrolyte interactions that elicit distinct electrochemical responses. To understand how the electrochemical characteristics of RAPs depend on molecular features, including redox moiety, macromolecular size, and …

Charge transfer engineering in Phenyl-modified Carbon Nitride-based hybrid systems: from powder Photocatalysts to Thin films
… however, its performance is limited by rapid charge carrier recombination, low mobility, and inefficient charge utilization. To overcome these intrinsic drawbacks, this thesis adopts charge transfer engineering as a central design strategy, focusing on controlling charge generation, …

A Study of Triboelectrification for Coal , Quartz and Pyrite
… coal cleaning depends profoundly on the surface charges of the particles involved. In general, the larger the difference between the charges of the particle to be separated, the higher the separation efficiency. The premise that coal and mineral matter can be triboelectrically charged differently …

Modeling and Experimental Measurement of Triboelectric Charging in Dielectric Granular Mixtures
… charging, the phenomenon by which electrical charge is exchanged during contact between two surfaces, has been known to cause significant charge separation in granular mixtures, even between chemically identical grains. This charging is a stochastic process resulting from random collisions …

Molecular-Level Understanding of Ionic & Electronic Charge Storage Mechanisms in Rechargeable Aluminum Batteries Using Sold-State NMR
<p>Rechargeable aluminum-ion batteries are safe and low-cost alternatives to traditional lithium-ion batteries due to the high volumetric capacity (8040 mAh/cm<sup>3</sup>) of aluminum. However, very few electrode materials have shown reversible aluminum ion intercalation. Intercalation …

BRIDGING EXPERIMENT AND THEORY IN PORPHYRIN CHEMISTRY: DEVELOPING MATERIALS FOR SENSING, OPTICAL, AND CATALYTIC TECHNOLOGIES
… optics (NLO). In all these fields, enhanced charge-transfer characteristics play a key role, and this requirement has guided the rational design of the systems developed during my doctoral project. The first part of my PhD (Chapter 2) centered on catalysis, specifically on the synthesis and …
