'Dewatering' of biomaterials consuming far less energyThe biobased materials that wil be used in industry more and more, have a major disadvantage: they mainly consist of water. Evaporating seems the most simple remedy, but this is very energy-inefficient: typically something you would like to avoid when making processes more sustainable. There are, however, other options that are driven by electricity and don’t have the need of warming the full volume of the material. Examples are hydrogels and membranes. The project ELECTRIFIED, the University of Twente together with four other universities and eight companies, will explore these ‘electric dewatering’ technology. They expect to reach a decrease in energy consumption of 50 to 90 percent.Read more
Hybrid nanomaterials as powerhouses for miniature energy storageThe development of new electronics requires a search for materials with unprecedented properties. For example, for local electrical energy storage on a chip and very fast charge-discharge thereof, so-called miniaturized pulsed-power devices, special ferroelectric materials are being studied. Scientists of the Inorganic Materials Science group (MESA+ Institute, University of Twente) alternate thin layers of two materials, lead zirconate (PbZrO3 – PZ) and lanthanum-doped lead zirconate titanate (Pb0.9La0.1Zr0.52Ti0.48O3 – PL) and show that the favorable properties of both materials reinforce each other in a multilayer. In addition, the layering also ensures that the maximum voltage that can be applied is significantly higher. These factors result in a strongly enhanced recoverable energy-storage density (increased by a factor of 4 to 128.4 J/cm3) with high release efficiency (81.2%). Moreover, the multilayer films are very robust, even after many charging cycles. The results were recently published in the leading journal Advanced Energy Materials.Read more
