Nanopowder nickel aluminate for benzothiophene adsorption from dodecane

Nickel aluminate reduced in hydrogen for 3 h at 500ºC was studied for desulfurization of model fuel comprised of dodecane spiked with benzothiophene (300 ppmw S). The nanopowder adsorbent was synthesized using combustion chemical vapor condensation, which created nickel aluminate with a BET specific surface area of 57.8 m2/g and average particle size of 11.7 nm. The nickel aluminate adsorbent removed 23 µmol of sulfur gram at breakthrough (<15 ppmw S). Regeneration by further heat treatment in hydrogen or air recovered 25% and 40% of original capacity, respectively.M.S.Committee Chair: Carter, W.B.; Committee Member: Cochran, Joseph; Committee Member: Venugopal, Ganes

Biomimetic and synthetic syntheses of nanostructured electrode materials

The scalable syntheses of functional, porous nanostructures with tunable three-dimensional morphologies is a significant challenge with potential applications in chemical, electrical, electrochemical, optical, photochemical, and biochemical devices. As a result, several bio-enabled and synthetic approaches are explored in this work (with an emphasis on peptide-enabled deposition) for the generation of aligned nanotubes of nanostructured titania for application as electrodes in dye-sensitized solar cells and biofuel cells. As part of this work, peptide-enabled deposition was used to deposit conformal titania coatings onto porous anodic alumina templates under ambient conditions and near-neutral pH to generate aligned, porous-wall titania nanotube arrays that can be integrated into dye-sensitized solar cells where the arrays displayed improved functional dye loading compared to sol-gel-derived nanotubes. A detailed comparison between synthetic and bioorganic polyamines with respect to titania film properties deposition rate provided valuable information for future titania coating experimental design given specific applications. The development of template-based approaches to single-wall titania nanotube arrays led to the development of a new synthetic method to create aligned, multi-walled titania nanotube arrays. Lastly, peptide-enabled deposition methods were extended beyond inorganic mineral and used for enzyme immobilization by cross-linking the peptide with the multicopper oxidase laccase. Peptide-laccase hybrid enzyme coatings improved both the amount of enzyme adsorbed onto carbon nanotube “buckypaper” and allowed the enzyme to retain more activity upon immobilization onto the surface.Ph.D

Green Banking and Green Central Banking Institute for law and finance series ;, 24./ edited by Andreas Dombret, Patrick S. Kenadjian.

In English.Includes bibliographical references.The books deals with the questions that really matter for green finance: Where will the money to finance the transition to a low carbon environment come from, how far do the banks' balance sheets stretch and where will the rest of the money come from? How much can we rely on the capital markets, especially in the EU, to get money to the parts of the economy which really need it, without greenwashing? How do governments organize not just a transition, but a just transition to a low carbon environment? Is it time to revisit received ideas about the proper role for centralbanks?Frontmatter -- Foreword -- Preface -- Contents -- Introduction -- The Authors -- I.
