Orange Peel Can Help Clean Up Dirty Water

Date October 27, 2008

Highly colored industrial waste water is a serious environmental problem as it seriously discolors waterways as well as blocking sunlight for photosynthesizing plant species in the water. Now, researchers in Algeria have discovered that nothing more sophisticated than orange peel could be used to remove acidic dyes from industrial effluent.

They describe their findings in a […]

Forgotten Experiment May Explain Origins of Life

Date October 17, 2008

Originally considered a dud, an old volcano-in-a-bottle experiment designed to mimic conditions that may have brewed the components of life might have been right on target.

After reanalyzing the results of unpublished research conducted by Stanley Miller in 1953, chemists realized that his experiment had actually produced a wealth of amino acids — the protein foundation […]

Catalyst For Water Oxidation Adopted From Plants: A Means For Energy-efficient Production Of Hydrogen?

Date August 26, 2008

Hydrogen will be one of the most important fuels of the future. It would be ideal to obtain hydrogen by splitting water instead of from petroleum. However, the electrolysis of water is a very energy intensive process, making it both expensive and unsustainable if the electricity necessary to generate it comes from the burning of […]

Key Photosynthesis Step Replicated: Scientists Learn From Nature To Split Water Into Hydrogen And Oxygen

Date August 18, 2008

An international team of researchers led by Monash University has used chemicals found in plants to replicate a key process in photosynthesis paving the way to a new approach that uses sunlight to split water into hydrogen and oxygen.

The breakthrough could revolutionise the renewable energy industry by making hydrogen – touted as the clean, green […]

Strange Molecule In The Sky Cleans Acid Rain, Scientists Discover

Date August 13, 2008

Researchers have discovered an unusual molecule that is essential to the atmosphere’s ability to break down pollutants, especially the compounds that cause acid rain.

It’s the unusual chemistry facilitated by this molecule, however, that will attract the most attention from scientists.
Marsha Lester, the University of Pennsylvania’s Edmund J. Kahn Distinguished Professor, and Joseph Francisco, William E. […]

Chemists Investigate Lost Reds In Homer Painting

Date June 17, 2008

More than 30 years ago, when Northwestern University chemist Richard Van Duyne developed a powerful new sensing technique, he never thought he would be using it to learn more about treasures in the Art Institute of Chicago’s collection — including a watercolor recently featured in the museum’s exhibition "Watercolors by Winslow Homer: The Color of […]

Science of Mentos-Diet Coke explosions explained

Date June 12, 2008

The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle’s base.

"If you drop […]

Skating Beads Of Water: Chemists Reproduce The Rose’s ‘Petal Effect’

Date April 25, 2008

The lotus flower is nature’s "slip n’ slide," where water beads skate along each petal’s surface like liquid metal. Now, chemists reveal the ying to the lotus’ frictionless yang: rose petals. Chemists have found the physical basis for the rose’s ability to grip water droplets in place, even when the flower is upside down. This […]

Sugar-powered Cars: World’s Most Efficient Method To Produce Hydrogen Developed

Date April 10, 2008

Chemists are describing development of a "revolutionary" process for converting plant sugars into hydrogen, which could be used to cheaply and efficiently power vehicles equipped with hydrogen fuel cells without producing any pollutants.

The process involves combining plant sugars, water, and a cocktail of powerful enzymes to produce hydrogen and carbon dioxide under mild reaction conditions. […]
