Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East Anglia. US government researcher Dr. Michael Daly... view more... (2001-09-07)

Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.   view more (2007-10-30)

NASA launches airborne study of arctic atmosphere, air pollution
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic.   view more (2008-04-02)

A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics".   view more (2008-07-01)

When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure.   view more (2008-10-17)

Nanomaterials vulnerable to dispersal in natural environment
Laboratory experiments with a type of nanomaterial that has great promise for industrial use show significant potential for dispersal in aquatic environments - especially when natural organic materials are present.   view more (2006-12-19)

Developing a safer form of acetaminophen
Scientists in Louisiana are reporting development of a process for producing large batches of a new and potentially safer form of acetaminophen, the widely used pain-reliever now the source of growing concern over its potentially toxic effects on the liver.   view more (2009-07-16)

Zinc oxide gives green shine to new photoconductors
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status.   view more (2009-03-19)

Toward plastic spin transistors
University of Utah physicists successfully controlled an electrical current using the "spin" within electrons - a step toward building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics.   view more (2008-08-18)

Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures.   view more (2007-03-12)

Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with hydrogen to form single bonds. This type of reaction,... view more... (2001-03-27)

Detecting synthetic fertilizers: Is it organic or not?
As organic farming becomes more common, methods to identify fraud in the industry are increasingly important. In a recent study in Journal of Environmental Quality, scientists successfully use nitrogen isotopic discrimination to determine if non-organic, synthetic fertilizers were used on sweet pepper plants.   view more (2008-02-04)

Sensor of plastic can be produced in a printing press
Electrochemical transistors made of plastic open myriad possibilities. Since both electrons and ions are active, they can function as a bridge between traditional electronics and biological systems. A new dissertation from Linköping University in Sweden describes a simple and inexpensive humidity sensor that can be manufactured in a printing... view more... (2005-02-08)

Scientists find way to clean up the drugs market
Researchers from the University of Cambridge and the Massachusetts Institute of Technology have made a breakthrough by using supercritical carbon dioxide (scCO2) as a reaction medium for the preparation of molecules of interest to the pharmaceutical industry.   view more (2004-09-13)

New Catalysts Developed at Oxford for Fischer-Tropsch and Oxidation Reactions
Oxford University researchers have developed an innovative process for preparation of catalysts, termed the Organic Matrix Combustion Method. It produces extremely active, selective and long-lasting catalysts. The catalysts use economical metals such as nickel and cobalt, and have been prepared for applications including the partial oxidation of... view more... (2002-10-04)

Where climate is made in a greenhouse world
New scientific results for the Late Cretaceous greenhouse indicate radically different climatic mechanisms operating about 75-90 million years ago compared to the ones that control today's climate.   view more (2006-06-02)

Metal-organic frameworks feel the pressure of Argonne scientists
