Mobile unit to measure emissions of nanoparticles from construction materials

Adding functional nanoparticles to materials is a way of incorporating new properties to improve conventional materials. But erosion over the years can make the material to release some of these nanoparticles into the air, which can be a health hazard. CSIC scientists have developed a method for monitoring construction materials and the nanoparticles released from them.

A portable device to measure photocatalytic activity of materials

Scientists at the CSIC have developed a device called “pholouring” to instantly measure the photo-catalytic activity of materials. The device detects the photo-catalytic activity through probes and color indicators which are in contact with the analysed material. Virtually any material, either solid, liquid or a solution, can be tested.

A device for reducing emissions in exhaust end pipes to near zero

Scientists at the CSIC have developed a photocatalytical device, which can be implemented in the exhaust end pipes of motor vehicles. It eliminates some of the pollutants contained in the smoke generated by combustion.

Non-toxic antimicrobial zinc oxide microparticles

Scientists at the CSIC have developed zinc oxide microstructures which have a very high antimicrobial activity, compared to the commercial nanoparticles. The particles obtained by the CSIC scientists have low toxicity, as they release low levels of toxic ions and reactive oxygen species. They can be applied for the elimination inhibition of microorganisms growing.

Three-dimensional structures of nanowires

Scientists at the Microelectronics Institute of Madrid have developed a new method to obtain 3D structures of nanowires. It is based on the use of porous templates, which are used as moulds. The applications are diverse in microelectronics, optic devices or energy sectors.

A temperature sensor in a wire

Scientists have developed a temperature sensor based on materials that deform with high temperatures. It is a microwire coated with concentric layers of different materials. Very small, it is a few millimeters larger and has a diameter of 40 micrometers.

Composites of nanocellulose and fibrous clay with special properties

CSIC scientists have obtained a material which combines nanocellulose and fibrous clays. It can be specifically modified for different applications. Similar to paper, the material can be used to obtain special papers such as bank notes, antimicrobial packages for food products, conductor or magnetic papers.

Solid blue-emitter in the UV-visible

At the CSIC’s Instituto de Ciencia de Materials de Madrid, scientists have obtained a new xerogel (a solid formed from a gel by drying, eliminating the solvent) which can be used as a blue emitter in solid state. It may be applicable to the fabrication of optoelectronics devices, fluorescent sensors, and organic light emitting diodes.

Glass against harmful bacteria and fungi

This new group of glass materials with biocide activity eliminates over 99.9% of pathogenic microorganisms, but has no toxic effects on the environment and on eukaryotic organisms (like animals and humans). This development could enable interesting applications for biomedical uses, water treatment and food packaging.
