Cation Exchange on 2-D PbSe Superlattices
(2017)PbSe quantum dots (QDs) of between 4 – 5 nm in size were synthesised by a heat-up and hot-injection method. These were used to perform oriented attachment whereby the QDs were connected via interatomic bonds to form extended ... -
CdSe Nanoplatelets: Synthesis, heterostructure, ion exchange and optical properties
(2015)CdSe nanoplatelets (NPLs) exhibit interesting opto-electronic properties. For example, they have narrow excitonic features and can therefore be used as monochromatic light emitters. Synthesis methods for CdSe NPLs emitting ... -
Chiral plasmonic nanohelices
(2015)Chirality of three-dimensional structures, i.e. structures that cannot be superimposed on their mirror image, is a very common geometric property in nature. Chirality has generated a lot of excitement in recent years, as ... -
Colloidal Allostery
(2017)Allostery is a type of adhesion process, where the substrate can be in multiple states, each with a different binding a affinity for the adsorbent. Allosteric processes are a fundamental requirement for cell life and better ... -
Concentration profiles of ferrofluids in magnetic fields
(2018)Ferrofluids are dispersion of magnetic nanoparticles which are often used in magnetic field gradients during applications. When the magnetic field gradient is sufficiently strong it can pull magnetic nanoparticles out of ... -
Correlated motion of semiflexible colloidal bead chains
(2018)Polystyrene colloids brushed with polyacrylic acid were prepared. From these particles, colloidal bead chains were prepared by aligning the particles using electric fi?elds. The thermal fluctuations of the bond angles in ... -
Crystallization of nanoparticles with square-shoulder interactions
(2017)Complex structures in colloidal systems are often stabilized by a competition between different length scales. Inspired by recent experiments on nanoparticles coated with polymers, we use Monte Carlo simulations to explore ... -
Degradation of chromogenic photoworks.
(2016)Photographic artworks, especially those where photographs are combined with other materials, so called photoworks, show signs of aging through color shift which results in value loss of the artworks. In order to find more ... -
Detect clustering in cells using Homo-FRET
(2015)In this research homo-FRET was used to detect clustering of EGFR in cells. To test this method reference constructs were made containing (2x)FKBP. A wide field microscope, polarizing beamsplitter and two cameras where used ... -
Developing Novel HTM Thin Films for Hybrid Perovskite Photovoltaics
(2016)With an increase of global energy consumption, utilizing sustainable energy sources such as solar energy has attracted significant research interest. Solar energy can be converted into electrical energy using photovoltaic ... -
Development of metal-organic frameworks for photocatalytic applications
(2015)In this research photocatalytic water splitting by metal-organic frameworks (MOFs) has been studied to replace fossil fuels by renewable energy. It has been found that MOFs can be immobilized on F:SnO2 (FTO) as a conductive ... -
Diffusion Behaviour in Superconducting Ti/Au Bilayers for Transition Edge Sensors to be Applied in Satellite Detectors
(2013)Controlling the superconducting critical temperature (TC)of Ti/Au bilayers is vital in the development of TES detectors. Previously empirical studies have been done on aging effects in Ti/Au and other superconducting ... -
Disquisition on the Acidity in Fluid Catalytic Cracking Catalysts Using Pyridine Probe Molecule Spectroscopy
(2018)The Fluid Catalytic Cracking (FCC) process has been used for over 75 years to convert crude oil into smaller hydrocarbons like gasoline, propylene and LPG. In this process a FCC catalyst is used composed of zeolite, alumina, ... -
Dynamics of femtosecond ablation on thin Au fi?lm
(2013)In this report we discussed the energy deposition and spread of femtosecond laser ablation on thin gold films. We acquired both experimental and computational results and compared these to get a better grasp of the dynamics ... -
Dynamics of Femtosecond Laser Modification Inside Fused Silica
(2013)This paper discusses the dynamics of fs-laser modification in fused silica by tightly focusing (NA = 0.25) a 200 fs, 800 nm pump probe. Transmission spectroscopy is performed during a pump-probe experiment with the 800 ...
