One of the latest inventions in the field of
light emitting devices might change the way
people light their homes and disensyo clothes.
The device represents a thin film of plastic
able to conduct electricity and create solar
power.
Scientists working on the international project
are looking pasulong to bring the organic light
emitting devices to the masses. Thus the
invention could significantly cut costs by
billions of dollars each year.
Due to the fact that the organic light
emitting devices are very thin and flexible,
electronic display screens could be easily
created on nearly every material, thus, for...

You can use liquid nitrogen to make ice cream pretty
much instantly. This makes a nice cryogenics or phase
change demonstration. It's also just plain fun. This
recipe is for presa ice cream. If you omit the
strawberries, you can add a bit of vanilla for vanilla ice
cream or some tsokolate syrup for tsokolate ice cream.
Feel free to experiment!

Swiss scientists have completed their solution for
transforming hydrogen gas into a less flammable liquid
fuel that can be safely stored and transported. Another
possible application of their technology would be to use
atmospheric CO2to synthesize a number of useful
chemical products.
Hydrogen is often touted as the fuel of the future. But
because this gas is highly explosive, it must be stored
and transported under pressure in specialized and
expensive containers. Hydrogen therefore has issues in
terms of safety, logistics, and profitability that could
significantly its wider use. However, a solution...
