[{"quality_controlled":"1","abstract":[{"text":"Characterization and application of (meso)porous materials often require information about the density of the respective samples. For example, the BET surface area is, by definition, normalized to the sample mass; hence, any comparison between samples of different composition needs to take into account their respective densities. Literature data on the densities of porous materials are scarce. Frequently, only bulk-phase densities are available which sometimes differ from those of porous samples, especially for amorphous systems, such as silica or carbon. The apparent density, i.e. the density of the sample excluding the gas-accessible pore volume, is typically determined by helium gas pycnometry utilizing specialized pycnometers. We demonstrate how to obtain the same data from standard N2 physisorption measurements as part of the regular measurement routine. We evaluate the method by reference measurements utilizing a non-porous reference sample (glass rod) to confirm the validity of the method. Then we present results on apparent density measurements of several mesoporous silica materials (MCM-41, MCM-48, SBA-15, KIT-6), mesoporous carbon (CMK-3, -5, -8, -9), and a variety of mesoporous metal oxides obtained by nanocasting.","lang":"eng"}],"citation":{"ieee":"C.

For a deeper understanding we studied the water sorption characteristics and compared the results to the conductive and dielectric properties studied by impedance spectroscopy. Spectra in a wide frequency range from 1 mHz to 1 MHz were recorded. Data analysis is performed using the Havriliak–Negami model. The MOFs are also tested as sensitive layers for capacitive humidity sensing by correlating the change in permittivity of the materials with the amount of physisorbed water.

The highly dispersed metal nitrates in the pores of the carbon matrix tend to react to the respective metal oxides at lower temperature than reported in the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal combustion of the CMK-3 carbon matrix also occurs at lower temperature, which is explained by a catalytic effect of the metal oxides present in the pores.

Compared to frequently investigated materials like tin dioxide (SnO2), tungsten trioxide (WO3), or gallium oxide (Ga2O3) indium oxide offers some unique properties. The most prominent one is its selectivity to oxidizing gases such as ozone (O3) or nitrogen dioxide (NO2) at low operating temperatures (<150°C). Combined with the photoreduction properties of nanocast, porous In2O3 highly selective sensing layers with a fast response can be prepared. In some cases even room temperature measurements are possible; therefore this material allows for designing low-power sensors without the need for special sensor substrates (e.g., μ-hotplates). Detailed analysis of the sensing mechanism reveals that known sensing models are not able to describe the observed effects. Therefore a new sensing model for ordered nanoporous In2O3 is presented which will be applicable for nonstructured material too.","lang":"eng"}],"quality_controlled":"1","date_created":"2021-10-08T15:52:23Z","place":"Berlin, Heidelberg","type":"book_chapter","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"status":"public","title":"New Sensing Model of (Mesoporous) In2O3","year":"2014","author":[{"full_name":"Wagner, Thorsten","last_name":"Wagner","first_name":"Thorsten"},{"first_name":"Nicola","last_name":"Donato","full_name":"Donato, Nicola"},{"id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722"}],"publication_identifier":{"issn":["1612-7617"]},"publication_status":"published","date_updated":"2023-03-08T10:33:20Z","_id":"25944","language":[{"iso":"eng"}],"user_id":"23547","doi":"10.1007/5346_2013_57"},{"type":"book_chapter","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"date_created":"2021-10-08T15:59:34Z","place":"Cham","abstract":[{"text":"In this paper, the development and validation of a shield prototype for resistive sensor array characterization with Arduino UNO, a platform based on ATmega328 microcontroller provided by ATMEL, is reported.

Thus, our aim is to focus on simple synthesis concepts for these materials, such as soft matter templating or nanocasting, which can be easily introduced by means of appropriate models in school chemistry education or school laboratories. In addition to facile and realizable syntheses in school, several experiments concerning catalysis and gas sensing will be presented, too. By these experiments the characteristics of nanoporous materials can be obviously demonstrated and additionally, these experiments can serve as a starting point for further experiments that could easily be developed by students themselves, particularly in relation to environmental issues.","lang":"eng"}],"citation":{"short":"T.

Contrary to the conventional double Schottky model the dominating factor for the change in resistance is a change of oxygen vacancy donor states (0.18 eV below the conduction band) in the bulk phase due to photoreduction, instead of chemisorption. For the faster reaction and regeneration we propose an explanation based on enhanced oxygen diffusion in the In2O3 crystal lattice, specifically dominant in the mesoporous structure. The response of ordered mesoporous In2O3 to NO2 is stronger than in case of unstructured bulk material (with an average grain size of ca. 40 nm). The reaction is significantly accelerated by illuminating the samples with UV light. However, the response of the mesoporous material is weaker in the illuminated case."}],"quality_controlled":"1","_id":"25954","language":[{"iso":"eng"}],"page":"488-494","user_id":"23547","doi":"10.1016/j.snb.2013.02.025","publication_identifier":{"issn":["0925-4005"]},"author":[{"last_name":"Wagner","first_name":"Thorsten","full_name":"Wagner, Thorsten"},{"last_name":"Kohl","first_name":"Claus-Dieter","full_name":"Kohl, Claus-Dieter"},{"full_name":"Malagù, Cesare","first_name":"Cesare","last_name":"Malagù"},{"full_name":"Donato, Nicola","last_name":"Donato","first_name":"Nicola"},{"full_name":"Latino, Mariangela","last_name":"Latino","first_name":"Mariangela"},{"full_name":"Neri, Giovanni","first_name":"Giovanni","last_name":"Neri"},{"last_name":"Tiemann","orcid":"0000-0003-1711-2722","first_name":"Michael","full_name":"Tiemann, Michael","id":"23547"}],"status":"public","year":"2013","title":"UV light-enhanced NO2 sensing by mesoporous In2O3: Interpretation of results by a new sensing model","article_type":"original","publication_status":"published","date_updated":"2023-03-08T10:34:05Z"},{"author":[{"full_name":"Haffer, Stefanie","first_name":"Stefanie","last_name":"Haffer"},{"full_name":"Walther, Till","last_name":"Walther","first_name":"Till"},{"full_name":"Köferstein, Roberto","first_name":"Roberto","last_name":"Köferstein"},{"full_name":"Ebbinghaus, Stefan G.","first_name":"Stefan G.","last_name":"Ebbinghaus"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael"}],"publication_identifier":{"issn":["1932-7447","1932-7455"]},"title":"Nanostructure-Related Magnetic Properties of Various Mesoporous Cobalt Oxide and Cobalt Ferrite Spinel Phases","status":"public","year":"2013","article_type":"original","publication_status":"published","date_updated":"2023-03-08T10:34:31Z","_id":"25953","language":[{"iso":"eng"}],"page":"24471-24478","user_id":"23547","doi":"10.1021/jp409058t","citation":{"mla":"Haffer, Stefanie, et al. “Nanostructure-Related Magnetic Properties of Various Mesoporous Cobalt Oxide and Cobalt Ferrite Spinel Phases.” <i>The Journal of Physical Chemistry C</i>, 2013, pp. 24471–78, doi:<a href=\"https://doi.org/10.1021/jp409058t\">10.1021/jp409058t</a>.","bibtex":"@article{Haffer_Walther_Köferstein_Ebbinghaus_Tiemann_2013, title={Nanostructure-Related Magnetic Properties of Various Mesoporous Cobalt Oxide and Cobalt Ferrite Spinel Phases}, DOI={<a href=\"https://doi.org/10.1021/jp409058t\">10.1021/jp409058t</a>}, journal={The Journal of Physical Chemistry C}, author={Haffer, Stefanie and Walther, Till and Köferstein, Roberto and Ebbinghaus, Stefan G. and Tiemann, Michael}, year={2013}, pages={24471–24478} }","ama":"Haffer S, Walther T, Köferstein R, Ebbinghaus SG, Tiemann M.

This review summarizes the basic aspects of materials synthesis, discusses some structural properties relevant in gas sensing, and gives an overview of the literature on ordered mesoporous gas sensors."}],"quality_controlled":"1","date_created":"2021-10-09T04:41:29Z","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"type":"journal_article","publication_identifier":{"issn":["0306-0012","1460-4744"]},"author":[{"full_name":"Wagner, Thorsten","last_name":"Wagner","first_name":"Thorsten"},{"full_name":"Haffer, Stefanie","first_name":"Stefanie","last_name":"Haffer"},{"full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian","id":"11848"},{"full_name":"Klaus, Dominik","last_name":"Klaus","first_name":"Dominik"},{"id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722","first_name":"Michael"}],"year":"2013","status":"public","title":"Mesoporous materials as gas sensors","article_type":"review","date_updated":"2023-03-08T10:34:56Z","publication_status":"published","language":[{"iso":"eng"}],"_id":"25952","page":"4036-4053","doi":"10.1039/c2cs35379b","user_id":"23547"},{"author":[{"full_name":"Wagner, Thorsten","first_name":"Thorsten","last_name":"Wagner"},{"full_name":"Tiemann, Michael","first_name":"Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","id":"23547"},{"full_name":"Kohl, Claus-Dieter","last_name":"Kohl","first_name":"Claus-Dieter"},{"full_name":"Morandi, Sara","first_name":"Sara","last_name":"Morandi"},{"full_name":"Malagù, Cesare","first_name":"Cesare","last_name":"Malagù"},{"full_name":"Donato, Nicola","first_name":"Nicola","last_name":"Donato"},{"last_name":"Latino","first_name":"Mariangela","full_name":"Latino, Mariangela"},{"first_name":"Giovanni","last_name":"Neri","full_name":"Neri, Giovanni"}],"title":"Mechanistic Model for UV light-enhanced NO2 Sensing utilizing Ordered Mesoporous In2O3","year":"2012","status":"public","date_updated":"2024-07-03T07:42:49Z","publication_status":"published","_id":"54994","publisher":"AMA Service GmbH, Von-Münchhausen-Str. 49, 31515 Wunstorf, Germany","language":[{"iso":"eng"}],"doi":"10.5162/imcs2012/p1.3.17","user_id":"23547","citation":{"ieee":"T.

Essential features of the model are photoreduction and a rate-limiting oxygen-diffusion step. Ordered, mesoporous In2O3 with a high specific surface area serves as a versatile system for experimental studies. Analytical techniques comprise conductivity measurements under a controlled atmosphere (synthetic air, pure N2) and temperature-resolved in-situ Fourier transform infrared (FTIR) spectroscopy.
