Phytotoxicity of soluble graphitic nanofibers to model plant species
Carbon nanomaterials are considered promising for applications in energy storage, catalysis, and electronics. This has motivated study of their potential environmental toxicity. Recently a novel nanomaterial consisting of graphene oxide (GO) wrapped around a carbon nanotube (CNT) core was synthesized. The resulting soluble graphitic nanofibers (SGNFs) were found to have superior catalytic ...

The hydrogen loop: the means for making the hydrogen economy realistic
The hydrogen economy has already started with the introduction of the Ovonic nickel metal hydride battery, which has enabled the rapid growth of hybrid vehicles. Reversible storage of hydrogen in a solid hydride permits the entire loop of hydrogen generation, storage and use, all of which have been placed some time in the future. It is often stated that the hydrogen infrastructure does not exist ...

Simultaneous production and separation of biohydrogen in mixed culture systems by continuous dark fermentation
Hydrogen production by dark fermentation is one promising technology. However, there are challenges in improving the performance and efficiency of the process. The important factors that must be considered to obtain a suitable process are the source of the inoculum and its pre-treatment, types of substrates, the reactor configurations and the hydrogen partial pressure. Furthermore, to obtain ...

ELAT-1400 Gas Diffusion Layer (GDL) Not “Discontinued”
After the original manufacturer of ELAT Gas Diffusion Layer (GDL) stopped producing the material, many of the fuel cell industry had to scramble for replacements and were continuing their projects based on inventory already purchased. We were no exception. After a fair amount of searching and evaluation, we finally found a replacement that had very similar mechanical properties. So, for a ...
