Scalable manufacturing of hierarchical nanostructures for thermal management
… coatings that have multiple length scales, or hierarchical features. Typically, the formation of hierarchical structures involves multiple steps and/or long processing times. In this new process, the hierarchical geometry is formed in a single step. The starting material-spherical copper …

Well-defined molecular brushes: Synthesis by a "grafting through" strategy and self assembly into complicated hierarchical nanostructures
… structures, as an attempt to construct nanostructures by covalent bonds totally. Detailed synthetic procedures for and characterization of molecular brushes, as well as complicated hierarchical nanostructures resulted from their self-assembly are reported. The synthesis of molecular …

Directing the self-assembly of short peptide derivatives
… which results in the controlled formation of hierarchical nanostructures. Herein, we investigate the possibility to achieve localised self-assembly of peptide derivatives exploiting different strategies to immobilize enzymes, thereby adding spatial control over the self-assembly process. We …

Synthesis and characterization of high-performance supercapacitor devices based on carbon/MnO2 composite and carbonized iron cations adsorbed onto polyaniline/nickel graphene foam
… and the MnO2-C electrode material with hierarchical nanostructures was successfully synthesized using KMnO4 solution and spent printing carbon grains method. The structural and morphological characterization of the as-synthesized electrode materials was carried out using scanning …

Hierarchical Semiconductor, Metal and Hybrid Nanostructures and the Study of their Light-matter Interactions
… this thesis explores the optical properties of hierarchical structures composed of nanoscale building blocks ranging from metals to semiconductors and composites, organized through bottom-up design methods. 1) By following the dynamic generation of hot-spots in self-assembled chains of gold …

Remote plasma assisted fabrication of functional organic and hybrid thin films and supported nanostructures
… novel multifunctional thin films and supported nanostructures by using remote plasma processes. The thesis is subdivided into eight chapters. At first, Chapter 1 includes the Introduction to the whole work developed throughouth the thesis. Chapter 2 gathers an overview of the thesis in Spanish …

Desulfurization by reactive adsorption on oxide/metal composites
… More specifically, different zinc oxide based nanostructures were studied for high and low temperature desulfurization applications. In addition, the focus was on moving away from the traditional practice of using oxides only as support materials. Oxides have traditionally been assigned the …

Growth and characterization of carbon nanostructures on zinc oxide nanostructures
… hybrid materials based on ZnO and carbon hierarchical nanostructures, and to test their performances when used as chemiresistors to detect low doses (~ ppm) of polluting gases, like ammonia and acetone. Nanostructures of ZnO and carbon, including carbon nanotubes, exhibit on their own …

TiO2 and ZnO metal oxides lattice defects driven magnetism and their contribution in discoloring of dyes
… currently observed only in similar morphological nanostructures. This remarkable observation suggests an existence of mixed and itinerate magnetism in one material. We have found a consistent correlation between the crystallite sizes and the shift in the exchange bias. Our ZnO hierarchical …
