Aminoxyl Catalyzed Electrochemical Ethanol Detection: Development of a New Breathalyzer Using Molecular Catalysis
Blood alcohol concentration (BAC) is the indicator of alcohol intoxication, and its measurement has emerged as the most common analytical procedure requested by law enforcement. Due to its volatility, ethanol vapor can be detected in breath, and its vapor concentration is proportional to BAC. While …

Graphite-conjugated catalysts : bridging heterogeneous and homogeneous catalysts
… carried out by either metallic heterogeneous or molecular homogeneous electrocatalysts. Metallic heterogeneous catalysts have a continuum of electronic states that distribute the redox burden of multielectron reactions, allowing for efficient catalysis. However, heterogeneous catalysts display a …

The α-helical conformation of polypeptides: design, regulation, and applications
… penetration field, self-assembly, as well as molecular catalysis, mainly due to the separated backbone-side chain (core-shell) structure, the anisotropic alignment of rigid rod-like geometry, and the macrodipoles, respectively. The goal of my Ph.D. research is focused on the design, …

Towards the rational design of nanoparticle catalysts
… ([BMIM]PF6) ionic liquid (Journal of Molecular Catalysis A: Chemical, 2008, 286, 114). The resulting nanoparticles were found to be effective and selective quasi-homogeneous catalysts towards a wide-range of hydrogenation reactions and the catalyst solution was reused for further …

The electrophilicity and chemistry of phosphate esters
… from polar effects rather than from intra-molecular catalysis. A comparison of the mass spectra of the heterocyclic and carbocyclic analogues, reveal differences which are significant (in the pyridyl substrates) and dramatic (in the quinolyl substrate) with regard to the fragmentation …

Molecular Hybrid Photocathodes Based on Silicon for Solar Fuel Synthesis
… products from H$_{2}$O and CO$_{2}$). However, molecular catalyst-based photocathodes remain scarcely reported and typically suffer from low efficiencies and/or stabilities due to inadequate strategies for interfacing the molecular component with the light-harvesting material, with benchmark …

Modification of Polymer Membranes: A Study of Crosslinking and In-Situ Growth of Palladium-Containing Nanoparticles in Polymer Matrices.
… key to the successful, economical production of molecular hydrogen for the eventual consumer market. Size-sieving glassy polymer membranes can separate H2 on the basis of its small size. Alternatively, reverse-selective rubbery polymers can expedite the passage and, hence, removal of CO2 due to …

A systematic study of enzyme-nanomaterial interactions for application in active surface decontamination
… of enzyme-nanosupport conjugates in industrial catalysis, energy production (i.e. biofuels and biofuel cells), biosensing and bioactive coatings are discussed with emphasis on enzyme-based decontamination coatings. It is emphasized that enzyme-based conjugates are capable of increasing enzyme …

Solar Driven Hydrogen Generation with Dye-Sensitised CuCrO2 Photocathodes
… scaffold for solar H2 production together with a molecular Ni catalyst and two different organic dyes based on perylene monoimide and diketopyrrolopyrrole chromophores. Improved activity over the mesoporous CuCrO2 films was associated with the novel morphology of the p-SC and the integration of a …
