Wafer-Scale Fabrication of Thin SiN Membranes and Au Films and Membranes with Arrays of Sub-um Holes Using Nanosphere Lithography

In this thesis, the wafer-scale fabrication of SiN membranes, Au films and Au membranes with arrays of sub-µm holes is described. Two conceptually different processes (1) and (2) were developed, both of which are based on nanosphere lithography (NSL) with ...

Optical limiting with complex plasmonic nanoparticles

Francesco Stellacci

Optical limiting by suspensions of Au nanoparticles is enhanced by several orders of magnitude with the use of complex plasmonic shapes, such as spined 'nanourchins,' instead of nanospheres. Similar enhancements are observed by changing the material of nan ...

Silicon nanowire AFM tips grown on released scanning probe cantilevers from stencil-deposited catalysts

Jürgen Brugger, Andreea Veronica Savu

We present a parallel, full wafer technique for deposition of catalyst on released scanning probe bodies for the growth of individual high aspect-ratio Si nanowire tips. 1-D probes are necessary for imaging high aspect-ratio nano-patterns, such as deep and ...

Synthesis of mesoporous titanium dioxide by soft template based approach: characterization and application in dye-sensitized solar cells

Michael Graetzel

The present work demonstrates the usefulness of the soft-template directed approach in preparing mesoporous titanium dioxide and applying it in dye-sensitized solar cells (DSSCs). Mesoporous titanium dioxide with nanograins of dimension in the range, 16-20 ...

Optical trapping and sensing with plasmonic dipole antennas

Olivier Martin

In this work, we study how to use a plasmonic dipole antenna as a multifunctional nanodevice for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR) -based sensing and optical trapping. An analytical model is implemented ...

Characterization of monomeric and gemini cationic amphiphilic molecules by fluorescence intensity and anisotropy

Kuppuswamy Kalyanasundaram, Guido Viscardi

Pyrene fluorescence intensity and conductivity measurements were used to determine the cmc of two monomeric surfactants namely, dodecyltrimethylammonium bromide and cetyltrimethylammonium bromide as well as two gemini surfactants, 16-3-16 2Br and 16-4-16 2 ...

Compartmentalization of Gold Nanocrystals in Polymer Microparticles using Electrohydrodynamic Co-Jetting

Francesco Stellacci

Polymer particles with micro- and nanoscale anisotropy have received increasing interest for their ability to simultaneously present different physical- and chemical properties. In this communication, we demonstrate that gold nanocrystals (NCs) can be sele ...

Nanostructured Ceramic Coatings for Drug Delivery

Heinrich Hofmann, Laurent-Dominique Piveteau, Arnaud Tourvieille de Labrouhe, Karin Dittmar

Drug eluting stents (DES) have been successfully implemented in clinical practice in the treatment against coronary artery disease. Compared to the implantation of bare metal stents, restenosis rates decreased significantly after stenting of DES into coron ...

Dynamics and disorder in surfactant-templated silicate layers studied by solid-state NMR dephasing times and correlated line shapes

David Lyndon Emsley, Bradley Floyd Chmelka

Surfactant-templated layered silicates are shown to possess complex compositional, structural, and dynamic features that manifest rich and interrelated order and disorder at molecular length scales. Temperature-dependent 1D and 2D solid-state Si-29 NMR mea ...
