Stratification patterns are formed when a bidisperse mixture of large rough grains and smaller more mobile particles is poured between parallel plates to form a heap. At low flow rates discrete avalanches flow down the free surface and are brought to rest ...
The use of nanomaterials has been shown to be promising in potential applications such as magnetic storage devices, nano-optical devices and sensors, amongst others. Such applications require the disposition of nanoparticles, of a wide variety of materials ...
Calcium phosphate cements (CPC) are increasingly used in the orthopedic field. This kind of cement has potential applications in bone defect replacements, osteosynthetic screw reinforcements or drug delivery. In vivo studies have demonstrated a good osteoi ...
Nanoscaled particles showing superparamagnetic behavior have been intensively studied in the past years for various applications. Nevertheless, the lack of well-defined particles remains an important problem. One of the major challenges is still the large- ...
Nanoporous films of cryst. anatase with intended application in dye-sensitized photovoltaic cells were studied by NMR cryoporometry, NMR diffusiometry, electron microscopy, and x-ray diffraction. The nanoparticles from which the films were subsequently sin ...
We apply the boundary element method to the analysis of the plasmon response of systems that consist of coupled metallic nanoscatterers. For systems made of two or more objects, the response depends strongly on the individual particle behavior as well as o ...
The objective of this study is to investigate the modelling of porosity and hydraulic conductivity changes in saturated porous media induced by the biological growth in pore space. Three different relationships between porosity changes and hydraulic conduc ...
A catalytic dispersion of fine metal particles mediates the photodissociation of water into hyrogen gas. A protective agent adsorptive to said particles and selected from among homopolymers, copolymers, hydrocarbyl radicals and polysaccharides stabilizes t ...

We here present an evaluation of the carrier performance of nanoparticles that are biofunctional, i.e. derivatized to provide a controlled biological activity, and environmentally responsive, since they respond to the presence of oxidants. In particular, w ...
