- Parahydrophobic Surfaces Made of Intrinsically Hydrophilic PProDOT Nanofibers with Branched Alkyl Chains
Claudio Mortier, Thierry Darmanin and Frederic Guittard
Article first published online: 28 JUL 2014 | DOI: 10.1002/adem.201400212
Parahydrophobic nanofiber surface (high apparent contact and high sliding angle) are elaborated by electrodeposition of PProDOT polymers with branched alkyl chains. Their wettability are due to the combination of nanofibrous structures with intrinsically hydrophilic materials to favor the Cassie-Baxter state.
- The Structubent: A Nanocomposite Solution to Compressed Natural Gas Storage
Steven Shimizu and Michael S. Strano
Article first published online: 28 JUL 2014 | DOI: 10.1002/adem.201400038
This study proposes the use of a structubent layer, composed of methane adsorbent particles and a structural matrix, as a liner for compressed natural gas (CNG) pressure vessels. The volume- and mass-specific methane capacities are compared with that of regular CNG and pure adsorbent systems, showing the structubent concept to be favorable under certain conditions.
- Intermetallic Layer Growth Kinetics in Sn-Ag-Cu System using Diffusion Multiple and Reflow Techniques
Magdalena Pawełkiewicz, Marek Danielewski and Jolanta Janczak-Rusch
Article first published online: 22 JUL 2014 | DOI: 10.1002/adem.201400226
The diffusion multiple (solid state) and the reflow soldering (solid and liquid state) techniques are used to study the diffusion controlled reactions in Sn-Ag-Cu system. The microstructural evolution at the interfaces, the kinetic rate constants and the respective activation energies of the Cu6Sn5 and Cu3Sn phases in the temperature range between 150 and 200 °C are presented.
- Material Selection, Manufacturing and Performance Test of Ceramic High-Temperature Heat Pipes Using Liquid Metals as Working Fluids
Peter Meisel, Sophie Schöne, Wolfgang Lippmann, Mario Raddatz, Antonio Hurtado and Uwe Gampe
Article first published online: 19 JUL 2014 | DOI: 10.1002/adem.201400176
Selection of ceramic construction materials and suitable solder materials is the basis for manufacturing sodium or zinc filled ceramic heat pipes. Tube filling with working fluid and the hermetical and durable sealing are key aspects for the functionality and service life of ceramic heat pipes.
- D2 Enertrode: Production Technologies and Component Integration of Nanostructured Carbon Electrodes for Energy Technology—Functionalized Carbon Materials for Efficient Electrical Energy Supply
Susanne Dörfler, Katja Pinkert, Mathias Weiser, Christian Wabnitz, Adrian Goldberg, Bernhard Ferse, Lars Giebeler, Holger Althues, Michael Schneider, Jürgen Eckert, Alexander Michaelis, Eckhard Beyer and Stefan Kaskel

Carbon as electrode material can be specifically tailored for fuel cell or supercapacitor applications. For both electrode systems, specific porosity is required. Vertically aligned multiwalled carbon nanotubes or films of mesoporous carbon are functionalized by incorporating nitrogen atoms into the CNTs or by infiltrating of transition metal precursors resulting in good catalytic behavior for oxygen reduction or increased specific capacitance.
