Electro-conductive ceramics based on nanocellulose

Scientists at the CSIC and at the Jožef Stefan Institute have developed a method to combine at the nanoscale cellulose nanofibers with ceramic nanoparticles such as alumina and zirconia, resulting in mechanically strong and highly electro-conductive ceramic materials that can be subjected to different types of machining, such as green machiningm or electro-discharge machining.

Iridescent photonic cellulose, which mimics the structural color of insects, with optical applications

A study developed at the ICMAB-CSIC and published in Nature Photonics describes the technique to provide structural coloration on a cellulose derivative through its nanostructuration. The colors obtained do not depend on pigments but on nanostructures that interact differently with the incident light. Applications include ecofriendly production of color in packaging systems or decorative paper, anti-counterfeiting technology, or biocompatible, biodegradable, washable and edible and low cost detectors, sensors or labels.

Anticorrosion microcapsules for construction materials

CSIC scientists have developed resin microcapsules containing corrosion inhibitors. This system allows the progressive and efficient release of the inhibitors, reducing both costs and environmental impact. This methodology can be applied on construction materials such as paint, coatings and, especially, reinforced concrete structures (RCS).

Organic and miniaturized photodetectors that absorb light beyond the visible range

They detect light below its absorption band and with a high efficiency. The presented devices demonstrate a wide spectroscopic photodetection and compactness of the device, making them much more portable and suitable for integrated electronics applications. The study was carried out by ICMAB researchers in collaboration with researchers from Dresden (Germany) and from Beijing (China).

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.
