08-06-2012: Scientists in Saudi Arabia have used a kitchen sponge as an electrode platform for supercapacitor devices. They made a MnO2–carbon nanotube–sponge supercapacitor electrode that demonstrated reasonably good electrochemical performance in both aqueous and organic electrolytes, they say.
They added that compared to aqueous electrolytes, the energy density of supercapacitors in 1M Et4NBF4 tripled and the value was improved six-fold when using 1M LiClO4 as the electrolyte. They also said that the cycling performance in organic electrolytes was inferior to aqueous electrolytes, but the devices in organic electrolytes retained a significant energy density advantage even after 10,000 cycles.

Understanding defects in graphene
The products of making graphene by thermally exfoliating graphite oxide are much more complex than previously thought, new research shows. The most common way to prepare graphene is by thermally reducing – or ‘exfoliating’ - graphite oxide. But the graphene produced in the process often con ... more
Dark-field microscopy coupled with capillary electrophoresis to see gold nanoparticles
Chinese scientists have combined interfacing dark field microscopy (DFM) with capillary electrophoresis (CE) and used it to “see” single gold nanoparticle (AuNPs) movement visually and in real time. The study also served to confirm the separation rules and fundamental theories of CE. more
Detecting harmful dye used to make ketchup red
It may soon be easier to protect consumers from dangerous condiments thanks to an electrochemical method developed by Chinese scientists that can spot the toxic azo dye, Orange II. They were able to spot the dye at nanomolar concentrations in ketchup and chilli products using the sensor. O ... more
