Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy

Omer A.M., University of Nottingham, UK

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of [...]

Aluminium-Doped ZnO Films and Nanowires by a Modified Chemical Vapor Deposition Technique

Choy K.L., Pung S.Y., University of Nottingham, UK

ZnO has unique properties such as wide-bandgap (3.37eV) and large exciton binding energy (60meV) at room temperature. These properties made ZnO a promising material for short wavelength photonic devices for examples, light emitting diode (LED) [...]

Advancements in the Supercritical Water Hydrothermal Synthesis (scWHS) of Metal Oxide Nanoparticles

Blood P., Lester E., Li J., Poliakoff M., University of Nottingham, UK

Supercritical Water Hydrothermal Synthesis (scWHS) is a relatively simple and environmentally friendly process for the production of potentially valuable metal oxide nanoparticles. This paper presents the conclusions of collaborative work between chemical engineers and chemists [...]

Nanostructures fabrication via self-assembly of hybrid block copolymer/nanoparticles in thin film

Fahmi A., Gindy N., University of Nottingham, UK

Fabrication of Nanostructures via self-assembly process is an elegant concept for the production the next generation of miniaturised devices. However, many challenges need to be overcome in 2D and 3D nanofabrication before the routine utilisation [...]

Polymer-based gene delivery system fabricated with the participation of a polyanion

Stolnik S., Sun Q., University of Nottingham, UK

A DNA/polycation/polyanion system is being designed, which is supposed to be a potentially improved system in comparison to the traditional gene delivery system (DNA/polycation system). The production of such a DNA/polycation/polyanion system is based on [...]

Synthesis and Characterization of Magnetorheological Fluids with Super Paramagnetic Nanomaterials in Polymeric Matrix

Fahmi A., Gindy N., Kancharla V., Liu Q., University of Nottingham, UK

Magneto-rheological (MR) fluids represent an exciting family of smart materials that have the unique ability to undergo rapid (within a few µs) changes in their apparent viscosity on the application of an external magnetic field. [...]

Polymer-Controlled Growth of CdSe Nanoparticles into Micro- and Nanowires

Fahmi A.W., Moriarty P., Oertel U., Stamm M., Steinert V., University of Nottingham, UK

This work reports an easy and effective method to prepare CdSe semiconductors nanoparticles stabilised by using amphiphile diblock copolymer polystyrene-block-polyvinylpyridine [PS-b-P4VP] in nonaqueous medium. spin coating on native oxide Si-wafers showed a core-shell structure of [...]
