We present a comprehensive study of a straightforward synthesis method via direct immobilization of several phosphonic acids and phosphoric acid esters on various mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due to the utilization of azeotropic distillation, there was no need to dry phosphonic acids, phosphoric acid esters, solvents, or silicas prior to synthesis. In addition to modeling phosphonic acids, immobilization of the important biomolecule adenosine monophosphate (AMP) on the porous supports was also investigated. Due to the high surface area of the mesoporous silicas, a possible catalytic application based on immobilization of an organocatalyst for an asymmetric aldol reaction is discussed.}}, author = {{Weinberger, Christian and Heckel, Tatjana and Schnippering, Patrick and Schmitz, Markus and Guo, Anpeng and Keil, Waldemar and Marsmann, Heinrich C. and Schmidt, Claudia and Tiemann, Michael and Wilhelm, René}}, issn = {{2079-4991}}, journal = {{Nanomaterials}}, title = {{{Straightforward Immobilization of Phosphonic Acids and Phosphoric Acid Esters on Mesoporous Silica and Their Application in an Asymmetric Aldol Reaction}}}, doi = {{10.3390/nano9020249}}, year = {{2019}}, } @article{28148, abstract = {{ The potential for biases being built into algorithms has been known for some time (e.g., Friedman and Nissenbaum, 1996), yet literature has only recently demonstrated the ways algorithmic profiling can result in social sorting and harm marginalised groups (e.g., Browne, 2015; Eubanks, 2018; Noble, 2018). We contend that with increased algorithmic complexity, biases will become more sophisticated and difficult to identify, control for, or contest. Our argument has four steps: first, we show how harnessing algorithms means that data gathered at a particular place and time relating to specific persons, can be used to build group models applied in different contexts to different persons. Thus, privacy and data protection rights, with their focus on individuals (Coll, 2014; Parsons, 2015), do not protect from the discriminatory potential of algorithmic profiling. Second, we explore the idea that anti-discrimination regulation may be more promising, but acknowledge limitations. Third, we argue that in order to harness anti-discrimination regulation, it needs to confront emergent forms of discrimination or risk creating new invisibilities, including invisibility from existing safeguards. Finally, we outline suggestions to address emergent forms of discrimination and exclusionary invisibilities via intersectional and post-colonial analysis. }}, author = {{Mann, Monique and Matzner, Tobias}}, issn = {{2053-9517}}, journal = {{Big Data & Society}}, number = {{2}}, title = {{{Challenging algorithmic profiling: The limits of data protection and anti-discrimination in responding to emergent discrimination}}}, doi = {{https://doi.org/10.1177/2053951719895805}}, volume = {{6}}, year = {{2019}}, } @article{25905, abstract = {{A nanocomposite material based on copper(II) oxide (CuO) and its utilization as a highly selective and stable gas-responsive electrical switch for hydrogen sulphide (H2S) detection is presented. The material can be applied as a sensitive layer for H2S monitoring, e.g., in biogas gas plants. CuO nanoparticles are embedded in a rigid, nanoporous silica (SiO2) matrix to form an electrical percolating network of low conducting CuO and, upon exposure to H2S, highly conducting copper(II) sulphide (CuS) particles. By steric hindrance due to the silica pore walls, the structure of the network is maintained even though the reversible reaction of CuO to CuS is accompanied by significant volume expansion. The conducting state of the percolating network can be controlled by a variety of parameters, such as temperature, electrode layout, and network topology of the porous silica matrix. The latter means that this new type of sensing material has a structure-encoded detection limit for H2S, which offers new application opportunities. The fabrication process of the mesoporous CuO@SiO2 composite as well as the sensor design and characteristics are described in detail. In addition, theoretical modeling of the percolation effect by Monte-Carlo simulations yields deeper insight into the underlying percolation mechanism and the observed response characteristics.}}, author = {{Paul, Andrej and Schwind, Bertram and Weinberger, Christian and Tiemann, Michael and Wagner, Thorsten}}, issn = {{1616-301X}}, journal = {{Advanced Functional Materials}}, title = {{{Gas Responsive Nanoswitch: Copper Oxide Composite for Highly Selective H2S Detection}}}, doi = {{10.1002/adfm.201904505}}, year = {{2019}}, } @article{35164, author = {{Raczkowski, Felix and Shnayien, Mary}}, journal = {{Tekniikan Waiheita}}, number = {{3}}, pages = {{57–67}}, title = {{{History and Aesthetics of Progress Indicators [Edistymispalkkien historia ja estetiikka]}}}, doi = {{10.33355/tw.86775}}, volume = {{37}}, year = {{2019}}, }
