Chemists at FAU develop a method for utilising nitrogen oxides

Chemists at FAU have developed a process in which nitrogen oxides generated during industrial processes can be used in the manufacture of colourants and medicines. Using the method, businesses will in future be able to combine the decontamination of exhaust fumes with the production of new substances.

Nitrogen oxides are a major environmental pollutant. Nitrogen and oxygen compounds are primarily formed during combustion, for example in automobile engines and coal and gas power plants, but also through other thermal and chemical techniques employed by industry. In order to clean these waste gases, the methods of post-combustion capture or catalytic reduction are employed – both of which are relatively complex and are also associated with certain disadvantages. But nitrogen oxides are not just unwanted toxins. In fact, recent research has shown that they can be used in the chemical synthesis of high-value products.

Changing Temperatures and Precipitation May Affect Living Skin of Drylands

Arid and semiarid ecosystems are expected to experience significant changes in temperature and precipitation patterns, which may affect soil organisms in ways that cause surfaces to become lighter in color and thus reflect more sunlight, according to a new U.S. Geological Survey study.

Extensive ice cap once covered sub-antarctic island of South Georgia

A new study reveals the sub-antarctic island of South Georgia – famous for its wildlife – was covered by a massive ice cap during the last ice age.

World's First Fluorescent Frog Found in the Amazon

Scientists have discovered the world’s first known naturally fluorescent amphibian — the South American polka-dot tree frog.

China's Severe Winter Haze Tied to Climate Change

China's severe winter air pollution problems may be worsened by changes in atmospheric circulation prompted by Arctic sea ice loss and increased Eurasian snowfall – both caused by global climate change.

California Deserts In 'Super Bloom' Thanks To A Wet Winter

In some parts of the country, cold weather is threatening crops. Meanwhile, California has been so unseasonably wet that its deserts are experiencing what's called a "super bloom." After years of drought, the normally arid desert is lush.

New UN Report Blames Pesticides for Food Insecurity

The United Nations says it’s time to overturn the myth that pesticides can feed the world and come up with better, safer ways of producing our food.

Wi-fi on rays of light: 100 times faster, and never overloaded

Slow wi-fi is a source of irritation that nearly everyone experiences. Wireless devices in the home consume ever more data, and it’s only growing, and congesting the wi-fi network. Researchers at Eindhoven University of Technology have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light. This was the subject for which TU/e researcher Joanne Oh received her PhD degree with the ‘cum laude’ distinction last week.

Skilled Workers More Prone to Mistakes When Interrupted

Expertise is clearly beneficial in the workplace, yet highly trained workers in some occupations could actually be at risk for making errors when interrupted, indicates a new study by two Michigan State University psychology researchers.

Astronomers observe a dying red giant star's final act

Using a powerful telescope, scientists view spiral pattern of gaseous emissions around LL Pegasi and its companion star.
