Observation and modeling of biological colloids with neutron scattering techniques and Monte Carlo simulations

In this study non-invasive neutron scattering techniques are used on soft condensed matter, probing colloidal length scales. Neutrons penetrate deeply into matter and have a different interaction with hydrogen and deuterium, allowing for tunable contrast using light and heavy water as solvents. The mesoscopic structure of materials is determined...

From dynamics to structure and function of model biomolecular systems

The purpose of this thesis was to extend recent works on structure and dynamics of hydrogen bonded crystals to model biomolecular systems and biological processes. The tools that we have used are neutron scattering (NS) and density functional theory (DFT) and force field (FF) based simulation methods. The quantitative and parameterfree link (in...

Discotic liquid crystals: From dynamics to conductivity

The dynamics and conductivity of the discotic liquid-crystal, hexakis(n-hexylox) triphenylene (HAT6), and charge-transfer complex that it forms with 2,4,7trinitro-9-fluorenone (TNF) are studied using quasielastic neutron-scattering (QENS) and Pulse-Radiolysis Time resolved Conductivity. These two techniques measure the molecular dynamics and...

Towards a hydrogen-driven society? Calculations and neutron scattering on potential hydrogen storage materials

For sustainable development, the resources of the earth need to be maintained and carbon dioxide emission should be avoided. In particular, we need to find an alternative for the use of fossil fuels in vehicles. Since long, hydrogen has been recognised as the fuel of the future because it exhausts only water when used in fuel cells and hardly...

Structure and Dynamics of Lithium in Anastase TiO2

A fundamental study on materials for Li-ion batteries

In April 1997 the program "Decentralized Production and Storage for Large-Scale Application of Renewable Energy" of the Delft Interfaculty Research Centre (DIOC) was launched. In this program various groups from several Faculties of the Delft University of Technology studied the feasibility of large scale application of renewable energy. Energy...
