The Instituto Tecnológico de Aragón (ITA), the Instituto de Nanociencia (INA) from Universidad de Zaragoza, Instituto de Investigación en Medio Ambiente y Materiales from Universidad de Pau, the Laboratorio de Ingeniería de Producción from Escuela Nacional de Ingenieros de Tarbes and the Departamento de Ingeniería de Polímeros from Universidad de Minho had launched an European research project to make plastics lighter through the use of nanotechnology and facilitate the transfer of this technology to SMEs.

The project objective is to develop suitable nanoparticles to give to plastic material the best mechanical properties with less weight.

The idea is to replace the reinforced plastic with fiberglass and part of this fiberglass with nanoparticles, and as a result of that it is obtained a lighter material that maintains or improves their properties.

The development of this material would have many industrial applications, especially in sectors such as automotive to construction machinery.

Molecular Switches Activated By Sunlight

A team of researchers from the University of La Rioja has managed to synthesize the first molecular switches activated by sunlight.

His research has been inspired by natural structures present in the retina. This work argues that when the light reaches the eyes of the person, it activates some of the proteins that make up the retina, causing a slight movement of rotation in the structure of its molecules. Inspired by this mechanism the research team has succeeded in synthesizing a new type of compounds that play such a mechanism. The incidence of sunlight makes the compost from one position to another, as if it were a tiny switch.

A big advantage over other compounds is the use of energy abundant, cheap and clean, it also does not damage the material on which it operates.

The small size of these compounds makes them particularly useful in biological and future applications of nanotechnology.

Quantum Dots Do Not Behave As Independent Systems

One of the most striking of nanotechnology is the quantum confinement or quantum dots: particles such as electrons are trapped in closed nano-structures, a phenomenon that generates the art optical and electronic properties with no equivalent in nature and with potential technological applications.

Until now, scientists had observed confinement isolated objects or irregular systems. An investigation, with the participation of the Centro de Investigación en Nanociencia y Nanotecnología CIN2 and the Swiss Nanoscience Institute, detected for the first time the formation of a regular series of electronic confinement on a copper surface. The finding could be useful in future applications for sensors and computer.

The study has overcome the difficulties that arise when creating regular structures capable of causing the confinement. The most prominent work is that regular confinement systems do not behave as independent, but interact with each other and form a new structure of electronic bands.

This finding would control different electronic properties of the surface of matter (in the case of this investigation, copper), which, in turn, would control different electronic properties, such as resistance.

The Numancia, football team of the Spaniard second division, will be the first football team wearing shirts produced in Spain with nanotechnology. The manufacture of the new shirts, called Ti-energy, is composed of silver and titanium nanoparticles.

The main properties of these shirts are stainless, antistatic and antibacterial, hundred percent breathable, waterproof and impermeable to any liquid.

With this technology, the water enters and leaves but the shirt did not get wet, so that the numantino players neither will be drenched in sweat, nor will be soaked and of course when it rains at the end of the match the shirt will be as clean as at the beginning.

The teams of the Italian soccer league, Atalanta and Parma, have used already these shirts with satisfactory results.
