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.}}, author = {{Wilke, Timm and Haffer, Stefanie and Weinberger, Christian and Tiemann, Michael and Wagner, Thorsten and Waitz, Thomas}}, issn = {{1936-7449}}, journal = {{Journal of Nano Education}}, pages = {{117--123}}, title = {{{Nanoporous Materials: Synthesis Concepts and Model Experiments for School Chemistry Education}}}, doi = {{10.1166/jne.2014.1044}}, year = {{2014}}, } @article{25947, abstract = {{Ordered mesoporous carbon with a high heteroatom (N, O) content was prepared by nanocasting from a melt of a eutectic mixture of fructose and urea (60/40 wt.-%; melting temperature ca. 65 °C).

This paper presents anodized aluminum (Al) as an effective and cheap alternative for ceramics like alumina (Al2O3) or aluminum nitride (AlN). Al has a significantly higher thermal conductivity as both named ceramics. In addition, the lower thermal stability of Al is still high enough to work with bismuth telluride based modules, which are most common. To show the advantages of the changed substrate, finite element method (FEM) simulations were performed. These simulations show that by changing the cold side substrate material the temperature drop across the substrate is reduced by 60 K. This correlates to a theoretical power gain of more than 20 {%}. Furthermore, Al can be shaped much easier than a ceramic material. The biggest advantage is obviously the price. Anodized Al is around twenty times cheaper than Al2O3. To demonstrate the easy fabrication of the proposed substrate, samples were prepared only with widely used processes like those used for conventional printed circuit boards.}}, author = {{Assion, F. and Geneiß, V. and Schönhoff, M. and Hedayat, C. and Hilleringmann, Ulrich}}, booktitle = {{Proceedings of the 11th European Conference on Thermoelectrics}}, editor = {{Amaldi, Andrea and Tang, Francois}}, isbn = {{978-3-319-07332-3}}, pages = {{83–88}}, publisher = {{Springer International Publishing}}, title = {{{Anodized Aluminum as Effective and Cheap Alternative Substrate for Thermoelectric Generators}}}, year = {{2014}}, } @inproceedings{39498, abstract = {{The figure of merit needs to be determined to rate the quality of thermoelectric materials (TM).

Particularly in the automotive sector, lightweight design principles continue to prosper rapidly. As a result, adjusted materials for different applications were developed. Due to the formation of intermetallic phases, most multi-material mixes cannot be welded and require adapted joining technologies. Mechanical joining technologies such as self-piercing riveting and mechanical clinching have proven effective methods of joining lightweight materials like aluminium and ductile steels. New high-strength steels are increasingly used in crash-sections, where limited deformation under impact load is required. These hot stamped steels have a very low elongation at break and therefore a low formability. Currently there is no joining by forming technology without pre-punching available using these grades of steels on die-side. The newly developed shear-clinching process is one possible method of joining this kind of material without additional elements. The fundamental idea of shear-clinching is a single-stage process in which pre-punching of the die-side material is performed by indirect shear-cutting and subsequent forming of the upper layer into this hole. This would immensely enlarge the application segment of mechanical clinching even if hot stamped steels are positioned on die-side. Fundamental studies are required to ensure process reliability and it is necessary to break down the joining process into fragments, like pre-punching and clinching with pre-punched sheet, and superpose them to form the combined procedure shear-clinching. This paper presents a detailed investigation of the sub-process clinching with pre-hole.}}, author = {{Merklein, Marion and Meschut, Gerson and Müller, Martin and Hörhold, Réjane}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, pages = {{1413--1420}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{Basic Investigations of Non-Pre-Punched Joining by Forming of Aluminium Alloy and High Strength Steel with Shear-Clinching Technology}}}, doi = {{10.4028/www.scientific.net/kem.611-612.1413}}, volume = {{611-612}}, year = {{2014}}, }
