The design of the multiuser facility supports—among others—the BIOMEX investigations into the stability and level of degradation of space-exposed biosignatures such as pigments, secondary metabolites, and cell surfaces in contact with a terrestrial and Mars analog mineral environment. In parallel, analysis on the viability of the investigated organisms has provided relevant data for evaluation of the habitability of Mars, for the limits of life, and for the likelihood of an interplanetary transfer of life (theory of lithopanspermia). In this project, lichens, archaea, bacteria, cyanobacteria, snow/permafrost algae, meristematic black fungi, and bryophytes from alpine and polar habitats were embedded, grown, and cultured on a mixture of martian and lunar regolith analogs or other terrestrial minerals. The organisms and regolith analogs and terrestrial mineral mixtures were then exposed to space and to simulated Mars-like conditions by way of the EXPOSE-R2 facility. In this special issue, we present the first set of data obtained in reference to our investigation into the habitability of Mars and limits of life. This project was initiated and implemented by the BIOMEX group, an international and interdisciplinary consortium of 30 institutes in 12 countries on 3 continents. Preflight tests for sample selection, results from ground-based simulation experiments, and the space experiments themselves are presented and include a complete overview of the scientific processes required for this space experiment and postflight analysis. The presented BIOMEX concept could be scaled up to future exposure experiments on the Moon and will serve as a pretest in low Earth orbit.}, language = {en} } @article{RistićFurboMoseretal.2016, author = {Ristić, Alenka and Furbo, Simon and Moser, Christoph and Schranzhofer, Hermann and Lazaro, Ana and Delgado, Monica and Pe{\~n}alosa, Conchita and Zalewski, Laurent and Diarce, Gonzalo and Alkan, Cemil and Gunasekara, Saman N. and Haussmann, Thomas and Gschwander, Stefan and Rathgeber, Christoph and Schmit, Henri and Barreneche, Camila and Cabeza, Luiza and Ferrer, Gerard and Konuklu, Yeliz and Paksoy, Halime and Rammelberg, Holger and Munz, Gunther and Herzog, Thomas H. and J{\"a}nchen, Jochen and del Barrio, Elena Palomo}, title = {IEA SHC Task 42 / ECES Annex 29 WG A1: Engineering and Processing of PCMs, TCMs and Sorption Materials}, series = {Energy Procedia}, volume = {91}, journal = {Energy Procedia}, issn = {1876-6102}, doi = {10.1016/j.egypro.2016.06.205}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-6629}, pages = {207 -- 217}, year = {2016}, abstract = {An overview on the recent results on the engineering and characterization of sorption materials, PCMs and TCMs investigated in the working group WG A1 "Engineering and processing of TES materials" of IEA SHC Task 42 / ECES Annex 29 (Task 4229) entitled "Compact Thermal Energy Storage" is presented.}, language = {en} } @article{JaenchenMeessenHerzogetal.2015, author = {J{\"a}nchen, Jochen and Meessen, Joachim and Herzog, Thomas H. and Feist, M. and de la Torre Noetzel, Rosa and de Vera, Jean-Pierre Paul}, title = {Humidity interaction of lichens under astrobiological aspects: the impact of UVC exposure on their water retention properties}, series = {International Journal of Astrobiology}, volume = {14}, journal = {International Journal of Astrobiology}, number = {3}, issn = {1475-3006}, doi = {10.1017/S147355041500004X}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-10837}, pages = {445 -- 456}, year = {2015}, abstract = {We quantitatively studied the hydration and dehydration behaviour of the three astrobiological model lichens Xanthoria elegans, Buellia frigida and Circinaria gyrosa by thermoanalysis and gravimetric isotherm measurements under close-to-Martian environmental conditions in terms of low temperature and low pressure. Additionally, the impact of UVC exposure on the isolated symbionts of B. frigida and X. elegans was studied by thermoanalysis and mass spectrometry as well as by gravimetric isotherm measurements. The thermal analysis revealed whewellite as a component of C. gyrosa which was not found in B. frigida and X. elegans. Neither the water retention nor the thermal behaviour of symbionts changed when irradiated with UVC under dry conditions. On the other hand, UVC irradiation of the wet mycobiont of B. frigida had a distinct impact on the hydration/dehydration ability which was not observed for the mycobiont of X. elegans. Possibly the melanin of B. frigida's mycobiont, that is not present in X. elegans, or a specifically damaged acetamido group of the chitin of B. frigida may be the sources of additional UVC-induced sorption sites for water associated with the UVC exposure.}, language = {en} } @article{HerzogJaenchen2016, author = {Herzog, Thomas H. and J{\"a}nchen, Jochen}, title = {Adsorption Properties of Modified Zeolites for Operating Range Enhancement of Adsorption Heat Pumps through the Use of Organic Adsorptive Agents}, series = {Energy Procedia}, volume = {91}, journal = {Energy Procedia}, issn = {1876-6102}, doi = {10.1016/j.egypro.2016.06.192}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-6614}, pages = {155 -- 160}, year = {2016}, abstract = {Faujasite zeolites with the highest possible Al-content and different cations as well as a dealuminated zeolite Y have been chosen to study the impact on the adsorption behavior in view of differed adsorptive agents for heat pumps or thermochemical storages.
