Towards practicable sensors using one-dimensional nanostructures
Nanomaterials, including nanoparticles, nanowires, nanotubes etc., are the object of much well deserving attention by researchers and the public alike. Because of their novel properties associated with their typically large surface to volume ratios and finite- or quantum-size effects, they offer an avenue of exploration for new and interesting physics, chemistry, biology and materials science. ...

Doped nano–phase tin oxide thin films for selective gas sensing
The paper deals with the development of ethanol gas sensing films of tin oxide nano–particles which are insensitive to saturated aliphatic hydrocarbons, such as gasoline vapours. Stannous alkoxide (particularly iso–propoxide) and tin 2–ethyl hexanoate in solution have been used for fabrication of tin oxide films on alumina substrates with two pre–fabricated gold electrodes. For achieving ...

The Spanish presence in the molecular sieve technology scenario
Molecular sieve research is a mature, but growing, area of interest within the Spanish scientific community. Indeed, Spanish researchers produce about 10% of the total number of publications in the zeolite field, covering new aspects of synthesis, characterisation and catalytic applications of those materials. More recently, there has been an emergent area focusing more on nanotechnological ...

Analytical simulation of interfacial DNA hybridisation for design of an optimal nanotechnology handheld biosensor
DNA biosensors are becoming ubiquitous at current scale-level of nanotechnology; but still remain in research laboratory. The project objective is accessing feasibility for a commercial off-the-shelf optimally designed versatile handheld DNA biosensor. Therefore, thorough understandings of the principles behind design of DNA biosensor during biophysical interfacial transduction were explored. The ...

Nonaqueous synthesis, assembly and formation mechanisms of metal oxide nanocrystals
Nonaqueous solution routes to metal oxide nanoparticles are a valuable alternative to the well-known aqueous sol-gel processes, offering advantages such as high crystallinity at low temperatures, robust synthesis parameters and avoidance of surfactants in order to control the crystal growth. In the first part of this paper we give an overview of the various solution routes to metal oxides in ...
