Particles and capsules are used as containers for active ingredients to delay their degradation and control the location and kinetics of their release. Key to a successful application of these containers is a good control over their size, composition, and ...
This thesis is dedicated to the growth and characterization of the optoelectronic properties of III-V semiconductor nanostructures namely nanowires and nanoscale membranes. III-V semiconductors possess promising intrinsic properties like direct band gap, h ...
Flows of granular materials widely occur in many industrial and natural environments. Particle-size segregation---the separation of grains of different sizes during flow---plays a crucial role in the behaviour of such flows. In spite of considerable effort ...
Engineered nanoparticles are the fastest growing nanotechnology product, and of increasing environmental concern. Examples include antimicrobial silver nanoparticles, iron oxide particles used in bulk scale for environmental remediation, and micro- and nan ...
Quantum mechanical confinement in electron-hole bilayer tunnel field-effect transistors (EHBTFETs) affects in a substantial way the band-to-band tunneling (BTBT) mechanism that constitutes their operating principle. Field-induced quantization is known to s ...
While cloud condensation nuclei (CCN) production associated with atmospheric new particle formation (NPF) is thought to be frequent throughout the continental boundary layers, few studies on this phenomenon in marine air exist. Here, based on simultaneous ...
In the present study we address the interactions of carboxyl-CdSe/ZnS core/shell quantum dots (QDs), as a model of water dispersible engineered nanoparticles, and metal resistant bacteria Cupriavidus metallidurans, largely used in metal decontamination. Th ...
Debris and pyroclastic flows often have bouldery flow fronts, which act as a natural dam resisting further advance. Counter intuitively, these resistive fronts can lead to enhanced run-out, because they can be shouldered aside to form static levees that se ...
We demonstrate the drastic improvement in absorbance and photoluminescence (UV-PL) of CdSe nanocrystals (NCs) upon adding both a carboxylic acid and an amine ligand to the cadmium acetate green chemistry source. We combined carboxylate complexes of lauric ...
The growth mechanism of silicon nanocrystals (Si NCs) synthesized at a high rate by means of expanding thermal plasma chemical vapor deposition technique are studied in this letter. A bimodal Gaussian size distribution is revealed from the high-resolution ...
