Book Synopsis Functionalization of Nanomaterial Surfaces for Light-harvesting and Nanotoxicology Applications by : Becca Anne Putans
Download or read book Functionalization of Nanomaterial Surfaces for Light-harvesting and Nanotoxicology Applications written by Becca Anne Putans and published by . This book was released on 2014 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to their unique reactivity and properties, nanomaterials are being used in many industrial and consumer products and applications. One area of particular interest to the work presented here is the harvesting of solar energy for electricity. Dye-sensitized solar cells (DSSCs) are reaching efficiencies where they are becoming viable options for consumer use. A nanoparticle film of metal oxides is used as a coating on one electrode to effectively separate charge carriers and move them through the external circuit to do work. The most commonly used materials for DSSCs are Ru based dyes and TiO2. In this work we have developed a new surface functionalization method that will allow for the use of other, more earth-abundant materials, such as Cu(I). This is accomplished by first attaching a "building-block" ligand to the metal oxide surface and then creating the rest of the light-harvester in situ. The on-surface assembly allows for regeneration of the photo-active molecule on the surface and eliminates the need to synthesize the full light absorbing complex with a binding group that will attach to the metal oxide. Nanoparticles are also being used in consumer products such as food, cosmetics, and clothing. These materials will inevitably end up in the environment and coming into contact with biological organisms, however, their toxicological effects are widely disputed. Some studies have shown that nanoparticles induce a toxic response in model organisms, while other studies show that the capping ligand around the particle is what is inducing this response. In this work we have developed a library of ligands that can be used on two model systems, gold and diamond, where we only manipulate one variable at a time. The ligands have a modular head group that allows for control of charge while keeping the backbone structure the same. In this way we will be able to tease out which variable has the most influence over biological interaction, the properties of the core material, or the properties of the ligand shell.

Book Synopsis Solar Light Harvesting with Nanocrystalline Semiconductors by : Oleksandr Stroyuk
Download or read book Solar Light Harvesting with Nanocrystalline Semiconductors written by Oleksandr Stroyuk and published by Springer. This book was released on 2017-11-07 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the use of nanocrystalline semiconductors in the harvesting of energy from solar light. It introduces promising methodology and technology which may help to increase the efficiency of light harvesting – one of the major challenges on the way toward sustainable energy generation.The book starts with a general introduction to the photochemistry of semiconductor nanocrystals. In the introductory chapter, the author also provides a frank and critical discussion on perspectives and limitations of the photocatalytic processes for solar light conversion including a historical account on semiconductor photocatalysis. He discusses that (and also why) it is a long way from laboratory prototypes to real sustainable technologies.The following chapters outline the conversion of solar light energy in semiconductor nanophotocatalysis on the one hand, and to (electric) energy in nanocrystalline semiconductor-based solar cells on the other hand. Topics addressed include nanophotocatalytic hydrogen production, artificial photosynthesis, quantum-dot sensitized liquid-junction and bulk heterojunction solar cells. Perspectives and opportunities, but also bottlenecks and limitations are discussed and the novel systems compared with established technology, such as classical silicon solar cells. While readers in this way learn to understand the basics and get introduced to the current research in the field, the final chapter provides them with the necessary knowledge about methodology, both in synthesis and characterization of semiconductor nanophotocatalysts and semiconductor nanomaterials, including examples for the practice of photocatalytic experiments and the studies of semiconductor-based solar cells.
Book Synopsis Vibronic Coherence in Light-harvesting Proteins and Semiconductor Nanomaterials by : Ryan Tilluck
Download or read book Vibronic Coherence in Light-harvesting Proteins and Semiconductor Nanomaterials written by Ryan Tilluck and published by . This book was released on 2020 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light harvesting in photosynthetic organisms employ complex arrays of highly ordered chromophores in proteins for the capture and transfer of energy from solar photons. The structural design of the light harvesting proteins leads to extensive delocalization across many molecules of the system. Recent studies demonstrate the involvement of quantum coherence in extraordinarily fast energy transfer pathways in photosynthetic light harvesting proteins. The extent of delocalization may also form vibronic excitons, vibronic excitons, arising from quantum coherent mixing of vibrations with the extensively delocalized electronic states. Vibronic excitons can greatly enhance the excitation energy transfer within light harvesting systems. In this dissertation, the detection and role of quantum coherence in the peridinin-chlorophyll protein (PCP), a mid-visible peripheral light-harvesting protein in marine dinoflagellates that delivers excitation energy to photosystem II, will be discussed. This dissertation will also discuss the role of vibronic coherences, involving organic surface ligands, in the hot carrier cooling process of CdSe semiconductor quantum dots (QDs). Optical broadband two-dimensional electronic spectroscopy (2DES) with ultrashort pulses has been employed on these systems to characterize nonradiative decay and energy transfer pathways in PCP and CdSe QDs. Understanding the advantage gained by the organism through the use of coherent energy transfer mechanisms may enable the development of more efficient light harvesting materials for use in photovoltaic cells or in photocatalysis.
