Nano-materials have huge surface areas in small, light packages; batteries work through chemical reactions that unfold on surface structures.
Glass and PTFE tubes as detection cells were put in small light-tight boxes to achieve miniaturization of batch- and flow-type chemiluminescence detectors for capillary electrophoresis.
While it is obvious that people in big, heavy cars fare better than people in small, light ones in collisions with other vehicles and with stationary objects, the analyses have failed to determine whether the benefit comes from the weight or from the size, according to the report, which was sponsored by the Energy Foundation, a nonprofit group that favors stricter fuel economy standards.
The health workers would have to paddle or walk, sometimes through the night, to collect fresh packs flown hundreds of miles in small, light aircraft from South Sudan's capital, Juba, to a number of remote locations in Leer and neighboring Mayendit county.
Then blend it in small, light motions until your whole face is covered in a thin layer of makeup.
To smudge it, simply rub your fingers over your eye in small, light motions when the eyeliner is half-dry.
Other trends on show in Basel included gold lace that mirrored the spring/summer catwalk trend, and a boom in smaller, lighter accessories for everyday wear.
"While a couple of challenges remain, this design brings us closer to using silicon anodes in smaller, lighter and more powerful batteries for products like cell phones, tablets and electric cars," said Yi Cui, an associate professor at Stanford and SLAC who led the research, reported today in Nature Nanotechnology.
MR. REDFORD continues to stress conservation measures like fuel-efficiency standards for cars, which sound harmless until you look at the added cost (which can vastly exceed the savings in gasoline) and the increased risk of being killed in smaller, lighter vehicles.
Fuel cell electric vehicles (FCEVs) offer longer ranges and provide more power in smaller, lighter packages than battery electric vehicles (BEVs).
The site makes you "check out as a regular member" if you want to avoid VIP, and that link is positioned to the right of the shopping basket in small, lighter-colored typeface.
