How to make this Soduim Acetate Sculptures your self?
1. Buy sodium acetate from unitednuclear.com for $24 a pound.
2. Pour the dry flakes into a pot of near-boiling water until no more will dissolve.
3. Let the water cool to room temperature, and touch it with a flake of the sodium acetate to turn it to nearly solid. To reuse, just reheat it until it’s liquid again and let it cool.

ANN ARBOR, Mich.—By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that’s as strong as steel but lighter and transparent.

By now you may have heard of the economic questions regarding using corn for ethanol production, but less attention has been paid to the environmental impact of using ethanol as an alternative to gasoline. Is ethanol more of a pollutant than gasoline? Surprisingly, the science says yes.
According to our Expert, who holds a PhD in Biochemical Engineering, a Master’s degree in Chemical Engineering, and has over 40 years experience performing biotechnology, bioengineering, and bioprocess research, both ethanol and gasoline deliver the same amount of carbon dioxide (CO2) into the atmosphere per gallon consumed. However, when compared on a per mile driven basis, burning ethanol actually produces 54% more CO2 as global warming pollutant than gasoline due to the fact that ethanol has lower fuel efficiency.
For the science buffs out there, the energy production produced by burning materials is proportional to the molecules of oxygen used. Here are the chemical formulas for the energy produced by burning octane via gasoline and by burning glucose via ethanol.

What is the scientific conclusion? To reduce CO2 as a global warming pollutant, stop using ethanol as an automobile fuel substitute!

To make the battery, Lee and his colleagues soaked a piece of paper in a solution of copper chloride and sandwiched it between strips of magnesium and copper. This sandwich was then laminated between two sheets of transparent plastic. When a drop of urine is added to the paper through a slit in the plastic, a chemical reaction takes place that produces electricity. The prototype battery produced about 1.5 volts, the same as a standard AA battery, and runs for about 90 minutes. Researchers said the power, voltage, and lifetime of the battery can be improved by adjusting the geometry and materials used. Urine contains many ions (electrically charged atoms), which allows the electricity-producing chemical reaction to take place in the urine battery. Other bodily fluids, such as tears, blood, and semen, would work easily as well to activate the battery.
