Thermoelectric generators: Linking Material properties and systems engineering for waste heat recovery applications
Sustainable Materials and Technologies, 2014Co-Authors: Saniya LeblancAbstract:Waste-heat recovery with thermoelectric power generators can improve energy efficiency and provide distributed electricity generation. New thermoelectric Materials and Material Performance improvements motivate development of thermoelectric generators for numerous applications with excess exhaust and process heat. However, thermoelectric generator product development requires solving coupled challenges in Materials development and systems engineering. This review discusses these challenges and indicates ways system-level Performance relies on more factors than traditional thermoelectric Material Performance metrics alone. Relevant thermo-mechanical and chemical Material properties, system components such as thermal interface Materials and heat exchangers, and system form factors are examined. Manufacturing processes and total system cost components are evaluated to provide product development and commercial feasibility contexts.

Gas sensors based on mass-sensitive transducers. Part 2: Improving the sensors towards practical application
Analytical and Bioanalytical Chemistry, 2020Co-Authors: Alexandru Oprea, Udo WeimarAbstract:Within the framework outlined in the first part of the review, the second part addresses attempts to increase receptor Material Performance through the use of sensor systems and chemometric methods, in conjunction with receptor preparation methods and sensor-specific tasks. Conclusions are then drawn, and development perspectives for gravimetric sensors are discussed.

Nanotechnological improvement of structural Materials – Impact on Material Performance and structural design
Cement & Concrete Composites, 2013Co-Authors: Michael Schmidt, C. Glotzbach, K Amrhein, Ss Kamaruddin, T Braun, R. TanzerAbstract:Abstract Within the last decades, the Performance of concrete has been significantly improved by applying different kinds of micro- and nanoparticles and by applying analytical methods from fundamental research disciplines that had not been used for construction Materials before, e.g. atomic force microscopy. One prominent result is Ultra-High Performance Concrete (UHPC) with its steel-like compressive strength which allows for slender but nevertheless very long lasting and thus sustainable concrete structures. On top of that several research projects performed at the University of Kassel, which this contribution likes to review, aim at making concrete an impervious, ceramic-like, acid resistant multifunctional “smart” Material with added values by further changing its nano- and microstructure and/or applying reactive coatings e.g. with the ability to degenerate air pollutants.

h2s biofiltration using expanded schist as packing Material Performance evaluation and packed bed tortuosity assessment
Journal of Chemical Technology & Biotechnology, 2012Co-Authors: Eric Dumont, M Rodriguez S Susa, L Ayala M Guzman, Yves AndresAbstract:BACKGROUND: The aim of this work was to test an innovative packing Material (expanded schist) for H2S biofiltration in order to determine the packing Material Performance in terms of elimination capacity, removal efficiency and pressure drop changes.Additionally,thechangesovertimeofbedcharacteristics,especiallytortuosity,wereevaluatedaccordingtoporosity measurements. RESULTS:SchistMaterialcantreatlargeloadingrates(upto30 g.m −3 .h −1 )with100%efficiencyatanemptybedresidencetime (EBRT) of 16 s, which is much better than most results reported in the literature. The porosity of the packed bed is around 40% (tortuosity estimated to range from 1.5 to 2.0) which leads to pressure drop measurements in the range of 10‐80 Pa m −1 . CONCLUSION: Schist is a good Material for H2S biofiltration in terms of mechanical stability, removal efficiency and effective treatment of high H2S loading rates. Schist is a Material that provides the appropriate environment for micro-organisms by itself. This trend should be confirmed over a long period. c � 2012 Society of Chemical Industry
