Scientists at the CSIC have developed a new method for the direct growth of graphene on dielectric substrates, avoiding the step of transferring the graphene from the copper catalyst substrates to the substrates of practical interest, as silicon or glass, avoiding therefore the economical cost. It is a scalable and reproducible method to use graphene in multiple applications.

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).

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.

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).
