Functional Materials From Self-Assembled Macrocycles
<p> Organic self-assembled materials have great utility as sensing materials, in gas storage, in separations, and as electronic devices. These assembled materials are typically held by non-covalent interactions such as hydrogen bonds, pi-pi stacking and dipole-dipole interactions. We are interested …

Thermal transport in self-assembled nanostructures
Understanding of phonon mediated thermal transport properties in nanostructured materials is essential for the intelligent design of next-generation microelectronic and thermoelectric devices. Presented here is the study of the thermal transport properties of model organic-inorganic, nanoscopically …

Self-Assembled Multilayered Dielectric Spectral Filters
… and mechanical properties. The Electrostatic Self Assembly (ESA) process is accomplished by the alternate adsorption of poly-anionic and poly-cationic molecules on progressive oppositely charged surfaces. This technique offers several advantages such as ease of fabrication, molecular level …

Self-assembled teams: attraction, composition, and performance
Contemporary teams are self-assembling with increasing frequency, meaning the component members are choosing to join forces with some degree of agency rather than being assigned to work with one another. However, the majority of the teams literature up until this point has focused on randomly …

Force microscopy of self-assembled amphiphilic films
… the study of monolayer water films (Chapter 4), self-assembled monolayers (Chapter 6), and to detect the presence and concentration of a 2D gas phase of molecules on a surface (Chapter 5). The invention of "soft contact" mode Atomic Force Microscopy imaging allows the direct imaging of surfactant …

Self-assembled molecular nanomaterials and their applications
Self-assembly of small molecules in water provides a bottom-up strategy to generate highly ordered nanostructures with dimensions on molecular (<10 nm) length scales. However, molecular self-assembled nanomaterials have traditionally been employed mostly in biological applications due to two …

AFM-Assisted Nanofabrication using Self-Assembled Monolayers
… nano-particles, and proteins to patterned self-assembled monolayers. A scanning probe nanografting technique was employed to produce patterns of various sizes, down to 10 nm. Thus, we are able to demonstrate a degree of surface patterning which is an order of magnitude smaller than that …

Self-Assembled Monolayers As Models For Silica
… and, where possible, elemental microanalysis. Self-assembled monolayers (SAMs) on gold were prepared using thiols 1, 2, and 3. SAMs were characterized using reflectance-absorbance infrared spectroscopy (RAIRS). Diagnostic vibrational modes were assigned by comparing RAIRS spectra to normal mode …

Micro and nanoelectrochemical modification of self-assembled monolayers
Gelöste Metallionen können an fest/flüssig-Grenzflächen eine Reihe von Reaktionen eingehen. Während galvanische Abscheidungen bereits recht gründlich untersucht sind, gibt es eine ganze Reihe weiterer Reaktionen, die auf molekularem Niveau unzureichend aufgeklärt sind, obwohl sie sowohl …

Formation and mechanics of self-assembled molecular gels
Molecular gels are associated with the formation of space spanning structures produced by aggregation of low molecular weight molecules that associate through hydrogen bonding, π-stacking, acid base or van der Waals interactions. One specific type of gel forming molecule is based on a hydrophobic …

Interfacial spallation/delamination properties of self-assembled monolayers
Self-assembled monolayers (SAMs) are short (nanometer-size) organic chains terminated by functional groups that can be selected to tailor the electrical, thermal and/or mechanical properties of interfaces. In this thesis, we investigate how the presence of SAMs affects the failure properties of …
