The result, they claim in a paper that will appear this month in the Journal of Physical Chemistry, is a nanofibre material with an extremely high ratio of surface-area to volume.
Supercapacitors have a big internal surface-area that allows a large amount of energy to be delivered rapidly and are used in some electric cars to provide a short burst of power for rapid acceleration and in hybrids to recover energy during braking.
The family of these materials includes much-touted, carbon-based members such as graphene and nanotubes, and are notable in part for their surface area-to-weight ratio.
BBC: 'White graphene' soaks up pollutants and can be re-used
The electronic nose is an array of nano-scale gas sensors--the maximized surface area of the nano-particles allows the most gas to pass over them--along with pattern recognition technology that can create a digital fingerprint (or noseprint, as the case may be) of specific smells.
But an eight-inch wafer has a surface area of over 50 square inches (A four-inch radius squared times Pi).

By integrating both the touch sensors and the solar cell layers into the same stack-up, surface area on the portable device may be conserved.
FORBES: Patent Approval Paves Way For Apple To Fire Up Solar Powered iPhone
The controller allows a Qi-compliant smartphone or other portable device to charge in a surface area of at least 70 mm by 20 mm, 400-percent larger compared to today's 18-mm by 18-mm "bull's-eye" charge space.
ENGADGET: TI details the wireless power chip in the Lumia 920, offers four times the charging area
The large, button-free touchpad offers plenty of surface area for intuitive scroll, flick, pinch zoom and pivot gestures.

Normally such forces are negligible, but the setae, with their spatula-like tips, maximise the surface area in contact with the wall.
Sadly the keyboard is a bit of a mixed bag -- the short travel and small surface area of the individual keys will be an issue for some.

It sheds the newer Cortex-A15 architecture of the Tegra 4 for a spruced-up 2.3GHz Cortex-A9 with the i500 LTE modem built directly into the chip die -- a move that cuts the surface area in half and simplifies the hardware, even as it supposedly outruns equivalent competition.
Syria's air and naval forces conducted live-fire manoeuvres aimed testing their readiness to repulse "any aggression against the homeland, " the official Sana news agency reported, with state TV pictures reportedly showing warplanes and helicopters firing missiles at targets in a desert area, as well as surface-to-air missiles hitting targets in the air.
Deep water: area where surface waves are not influenced by the sea-bottom.
Malton, Old Malton and Norton are defended from the river but surface water and backed-up drains have flooded several properties in the area.
This film is form-fitted onto an audio device and creates wide area surface contact with the skin, or the inside of the ear canal.
As the name implies, it's all based around pressure: a light touch performs the usual commands, while squishing the thumb's wider surface area against the screen allows the equivalent of a multi-touch gesture, such as a pinch to zoom.
When you tack that figure on with the 30.3 x 18.3-inch (769.3 x 463.74mm) surface area that also remains relatively unchanged, you'll find a substantial amount of space will need to be dedicated to the high-end peripheral.

Navigation and interaction are easy with the precision on-board pen, full-size keyboard and new five button clickpad that boasts 20 percent more surface area than traditional ThinkPad clickpads.
The typical barrel of a high-power rifle has exterior grooves, called flutes, to reduce weight and create more surface area to enable the barrel to cool faster.
The elephant distributes its weight at least over all 4 feet, and even if standing on one leg, over the area of the one foot- you might actually get more damage from a good stomp with a heel that has a small surface area.
