Dalla Longa, F. (author), Nogueira, L.P. (author), Limberger, J. (author), van Wees, J.D.A.M. (author), van der Zwaan, B.C.C. (author)The use of geothermal energy in Europe is expected to grow rapidly over the next decades, since this energy resource is generally abundant, ubiquitous, versatile, low-carbon, and non-intermittent. We have expanded and adapted the integrated assessment model TIAM-ECN to more adequately reflect geothermal energy potentials and to better represent...article 2020

Donkers, P. (author), Gao, K. (author), Houben, J. (author), Huinink, H. (author), Erich, B. (author), Adan, O. (author)A promising heat storage technique is based on thermochemical materials (TCM). Such materials are often used in closed systems under vacuum conditions, which is demonstrated in several projects in the European H2020 R&D programs. In this type of systems, non-condensable gasses (NCG) may have a significant effect on the reactor performance. This...article 2020

(author), Setzpfandt, F. (author)Optically resonant high-index dielectric metasurfaces featuring Mie-type electric and magnetic resonances are usually fabricated by means of planar technologies, which limit the degrees of freedom in tunability and scalability of the fabricated systems. Therefore, we propose a complimentary post-processing technique based on ultrashort (≤ 10 ps)...article 2020

Detz, R.J. (author), van der Zwaan, B.C.C. (author)The microwave oven has penetrated into many kitchens throughout the world and has substituted old polluting forms of cooking with new cleaner ways. Its exponential market uptake in the residential sector has been realized thanks to substantial cost reductions during its deployment phase, which started more than 70 years ago. Today, the annual...article 2020

Koirala, B.P. (author), van Oost, E. (author), van der Windt, H. (author)With energy transition gaining momentum, energy storage technologies are increasingly spotlighted as they can effectively handle mismatches in supply and demand. The decreasing cost of distributed energy generation technologies and energy storage technologies as well as increasing demand for local flexibility is opening up new possibilities for...article 2020

Shkatulov, A. (author), Joosten, R. (author), Fischer, H. (author), Huinink, H. (author)The advent of thermochemical energy storage (TcES), that is, storage of thermal energy by means of reversible chemical reactions, incites finding pathways of stabilization of thermochemical materials for thermal batteries of the future. Currently, salt hydrates such as LiCl·H2O, CaCl2·6H2O, and SrBr2·6H2O are being actively studied for TcES in...article 2020

Theelen, M. (author), Ntinas, V. (author), Steijvers, H. (author), Mannetje, H. (author), Vroon, Z. (author)Aluminum doped zinc oxide (ZnO:Al) films were deposited by sputtering on borosilicate glass (sodium poor) and soda lime glass (sodium rich). These films were exposed up to 1032 hours of damp heat (85 °C/85 % relative humidity) to study the influence of among others the sodium content of the substrate on the ZnO:Al stability. A decrease in...article 2020

Bouma, R.H.B. (author), Griffiths, T.T. (author), Tuukkanen, I.M. (author)To ensure safety and reliability, it is important that the explosives and other materials used in munitions do not interact adversely either physically or chemically. Data obtained by heat flow calorimetry on nitrocellulose-based propellants have been reviewed with the aim of identifying improved chemical compatibility assessment criteria. It...article 2019

(author), Westerhof, E. (author), de Baar, M.R. (author)The successful use of a tokamak for generating fusion power requires an active control of magnetic instabilities, such as neoclassical tearing modes (NTMs). Commonly, the NTM location is determined using electron cyclotron emission (ECE) and this is used to apply electron cyclotron heating (ECH) on the NTM location. In this paper, an inline ECE...article 2019
