This book was released on 2010-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le but de cette thèse a été de fabriquer des réseaux de nanofils et de nanotubes de l'oxyde de zinc (ZnO) de dimensions contrôlées en utilisant la méthode de réduction électrochimique de l'oxygène moléculaire. Plusieurs approches concernant le contrôle des dimensions de ces nanofils ont été investiguées. Après l'étude du mécanisme de formation des nanofils, nous avons proposé une nouvelle méthode pour obtenir des réseaux de nanotubes de ZnO par dissolution des coeurs des nanofils. Les propriétés optiques, électriques et structurales des nanofils et des nanotubes de différentes dimensions, obtenus avec différents conditions de dépôt ont été étudiées dans cette thèse. Finalement, des cellules ETA, constituées de ZnO/CdSe/CuSCN, ont été étudiées en utilisant les réseaux obtenus. Les effets de la morphologie et des dimensions des nanofils et nanotubes sur la diffusion de la lumière et la performance électronique des dispositifs ont été étudiés. Cela nous a permis de mieux comprendre les mécanismes optiques et électroniques impliqués dans ce type de cellule solaire ouvrant de nombreuses possibilités pour améliorer leur performance.

Download or read book Multifunctional Oxide Based Materials From Synthesis to Application written by Teofil Jesionowski and published by MDPI. This book was released on 2019-09-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Download or read book Double Gyroid Structured Functional Materials written by Maik Rudolf Johann Scherer and published by Springer Science & Business Media. This book was released on 2013-06-25 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of new high-tech applications and devices has created a seemingly insatiable demand for novel functional materials with enhanced and tailored properties. Such materials can be achieved by three-dimensional structuring on the nanoscale, giving rise to a significant enhancement of particular functional characteristics which stems from the ability to access both surface/interface and bulk properties. The highly ordered, bicontinuous double-gyroid morphology is a fascinating and particularly suitable 3D nanostructure for this purpose due to its highly accessible surface area, connectivity, narrow pore diameter distribution and superb structural stability. The presented study encompasses a wide range of modern nanotechnology techniques in a highly versatile bottom-up nanopatterning strategy that splits the fabrication process into two successive steps: the preparation of mesoporous double-gyroid templates utilizing diblock copolymer self-assembly, and their replication with a functional material employing electrochemical deposition and atomic layer deposition. The double-gyroid structured materials discussed include metals, metal oxides, and conjugated polymers, which are applied and characterized in high-performance devices, such as electrochromic displays, supercapacitors, chemical sensors and photovoltaics. This publication addresses a wide range of readers, from researchers and specialists who are professionally active in the field, to more general readers interested in chemistry, nanoscience and physics.
