Researchers Remove Excess Fluoride from Water
In the United States and other developed countries, fluoride is often added to drinking water and toothpaste to help strengthen teeth. But too much naturally occurring fluoride can have exactly the opposite effect. Large amounts of fluoride can lead to dental fluorosis and skeletal fluorosis.

Materials Use Light/Dark to Purify Air
Removing the smell of new carpet from a room may eventually be a matter of turning the lights on or off. Manindu Weerasinghe, a Kansas State Univ. doctoral candidate in chemistry, Sri Lanka, is studying materials that use light or darkness to purify air filled with toxins that are harmful to human health and the environment. Her research could one day lead to filters, humidifiers and other devices that can detoxify air in windowless rooms, manufacturing facilities and other indoor areas.

Miracle Tree’s Seeds Purify Water
A natural substance obtained from seeds of the “miracle tree” could purify and clarify water inexpensively and sustainably in the developing world, where more than 1 billion people lack access to clean drinking water, scientists report. Research on the potential of a sustainable water-treatment process requiring only tree seeds and sand appears in ACS’ journal Langmuir.

Chemists Construct Molecular Traps for Nanomaterials
Using clever but elegant design, Univ. at Buffalo chemists have synthesized tiny, molecular cages that can be used to capture and purify nanomaterials. Sculpted from a special kind of molecule called a “bottle-brush molecule,” the traps consist of tiny, organic tubes whose interior walls carry a negative charge. This feature enables the tubes to selectively encapsulate only positively charged particles.
