The type I R-M enzyme EcoR124I is a multifunctional, multisubunit molecular motor with the ability to self-assemble. In the presence of hydrophobic compounds, subunit disassembly has been observed leading to the possibility of using the enzyme as a nanoactuator in toxicity biosensors. A better understanding of single molecule interactions between the subunits has been investigated using atomic force microscopy (AFM), a powerful tool for measuring forces and dynamics between single molecules with a picoNewton sensitivity.

AD is part of a family of Th-2 driven diseases and is often the first of these atopic diseases to manifest. The development of AD is often followed by asthma and allergic rhinitis later in life (a phenomenon known as the ‘atopic march’).

Particularly, the nacre-mimetic brick-and-mortar structure has shown excellent mechanical properties as well as gas barrier properties and optical transparency. Along with these intrinsic properties, the layered structure has been designed to serve as sensing devices. Here we expand the multi-functionality of nacre-mimetics by designing an optically transparent and electron conductive coating that reacts to high-pressure based on PEDOT:PSS and nanoclay.

Abstract:
The adaptor protein Shb has been implicated in the signaling of several tyrosine kinase receptors and previous studies have suggested a role for Shb in the signal transduction of T cells. Shb associates with the T cell receptor (TCR) and partakes in the signal propagation of activated T lymphocytes. In order to explore Shb’s influence on TCR signaling in vivo, T cell development and function was studied in a Shb knockout mouse. The loss of Shb led to aberrant TCR signaling in both thymocytes and peripheral CD4+ TH cells, with elevated basal phosphorylation of key components in the signal casca

Abstract:
This thesis deals with systems of interacting particles with very low energy in the limit where the particle-particle scattering is much larger than the range of the interactions. We use a quantum-field-theory approach which allows us to study both few-body and dense-matter systems in a unified framework. This allows to introduce composite fields of two and three particles (when appropriate). The quantum corrections are calculated nonperturbatively with the Functional RenormalisationGroup. We deal with three types of systems. First we study systems with three and four scalar particles. For thr
