de Jong, A.J. (author), Fischer, H. (author)Hygroscopic salts exhibiting fast and reversible hydration are promising systems for seasonal heat storage, providing the possibility of storing excess solar energy from the warm season for later use during the cold season. For heat storage, the salt is dehydrated with the available heat, and for heat recovery, the salt is rehydrated. There are...article 2018

Obesity is associated with the development and progression of osteoarthritis (OA). Although the infrapatellar fat pad (IFP) could be involved in this association, due to its intracapsular localization in the knee joint, there is currently little known about the effect of obesity on the IFP. Therefore, we investigated cellular and...article 2017

(author)The awareness of the possible presence of toxic chemical compounds at and around military compounds and other critical infra structures is crucial and normally monitored by point detectors. The disadvantage of these type of detectors is that large quantities (organized in a network) are needed when a large area is to be controlled. Secondly...conference paper 2016

(author)Long-term and compact storage of solar energy is crucial for the eventual transition to a 100% renewable energy economy. For this, thermochemical materials provide a promising solution. The compactness of a long-term storage system is determined by the thermochemical reaction, operating conditions, and system implementation with the necessary...conference paper 2016

De Jong, A.J. (author), Stevens, R. (author), Rentrop, C. (author), Hoegaerts, C. (author)One of the bottlenecks for realizing a commercial system for thermochemical heat storage using hygroscopic salts is corrosion induced by chemical side-reactions. E.g. when Na2S hydrates are used, we basically deal with corrosion caused by the production of the volatile H2S, threatening metal parts in the reactor and the vacuum system. Based on...conference paper 2015

(author)Bottlenecks for realizing a commercial system for thermochemical heat storage (TCS) with hygroscopic salts are the chemical, physical and mechanical stability of the salt under operation conditions. Hence, improved knowledge of thermochemical materials (TCMs) is critical to spur progress in TCS system development. Sodium sulfide hydrates (Na2S...conference paper 2015

Trausel, F. (author), de Jong, A.J. (author), Cuypers, R. (author)Solar energy is capable of supplying enough energy to answer the total demand of energy in dwellings. However, because of the discrepancy between energy supply and energy demand, an efficient way of storing thermal energy is crucial. Thermochemical storage of heat in salt hydrates provides an efficient and compact way of storing solar energy....article 2014
