New boost to future calcium batteries

A recent study demonstrates the feasibility of the electrochemical extraction of calcium from a metal oxide, which could be used as a cathode (positive electrode) for calcium batteries.The study was carried out in collaboration with Toyota Motor Europe, and has resulted in a patent.

Minimalist biostructures designed to create nanomaterials

Researchers from the IBB-UAB and from the ICMAB-CSIC have obtained four molecules of only seven amino acids with the ability to self-assemble, which enables a fast and non expensive process to obtain nanomaterials for biomedical and nanotechnological purposes. They have used them to create one of the most resistant bionanomaterials described until now.

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.

A cheaper graphene synthesis method

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.

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.
