Nanoparticle-Substrate for fuel cells, electrolyzers, and chemical reactors and sensors

19.04.2010
By electrodeposition of crystalline nanoparticles onto a conducting substrate (for example a PTFE enhanced carbon fiber ultrahydrophobic sheet) for the first-time, it becomes possible to selectively create platinum-nanoparticles of the size of about 2 nm onto the bumps of the substrate without agglomeration. One advantage of this procedure is that diffusion through ultra-hydrophobic pores into inner gas conducting structures is avoided. The major benefits consist in the reduced need of platinum and a decreased number of process steps for the production. Possible applications of this technology are: all types of polymeric-electrolyte fuel cells (PEMFC, HT-PEMFC, DMFC, DEFC), all types of electrolyzers (H20, NaCl, HCl, etc.), electrochemical sensors and chemical reactors (consumable hydrogen anode, consumable oxygen cathode, etc.).

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
