When human and machine agree about iridium oxide

A human research team and a machine learning algorithm have found that we need to rethink much of what we know about iridium oxide.


Iridium oxide is an excellent catalyst for electrochemical reactions, and is typically used for the production of energy carriers such as hydrogen from water. Now it turns out that research on iridium oxide carried out so far has been based on a wrong basic assumption: The arrangement of the atoms on its surface is completely different to that previously assumed.

The way in which this surprising result was determined gives a tantalizing first glimpse of how research might be performed in the future: a collaborative effort between a human research team and artificial intelligence analyzed the same problem, and came to the same conclusion. Since the researchers at the TU Wien and the TU Munich reached the same result at the same

Rising nitrous oxide emissions could put Paris Agreement goals out of reach

Oct. 7 (UPI) — Around the world, nitrous oxide emissions are rising, imperiling the effort to meet the climate goals set by the Paris Agreement.

According to a new study, published Wednesday in the journal Nature, the growing use of nitrogen fertilizers by industrial agriculture has led to a dramatic increase in N2O emissions.

For the study, researchers analyzed major N2O sources and sinks all over the world. The effort was aided by scientists from 48 research institutions in 14 countries.

“This study presents the most comprehensive and detailed picture to date, of N2O emissions and their impact on climate,” lead study author Parvadha Suntharalingam, climate scientist at the University of East Anglia in Britain, said in a news release.

The data showed modern atmospheric nitrous oxide levels are 20 percent higher than preindustrial levels, increasing to 331 parts per billion in 2018 from 270 parts per billion in 1750.

Rising nitrous oxide (N2O) emissions are jeopardizing the climate goals of the Paris Agreement, according to a major new study by an international team of scientists.


The growing use of nitrogen fertilizers in the production of food worldwide is increasing atmospheric concentrations of N2O—a greenhouse gas 300 times more potent than carbon dioxide (CO2) that remains in the atmosphere for more than 100 years.

Published today in the journal Nature, the study was led Auburn University, in the US, and involved scientists from 48 research institutions in 14 countries—including the University of East Anglia (UEA) in the UK—under the umbrella of the Global Carbon Project and the International Nitrogen Initiative.

The aim was to produce the most comprehensive assessment to date of all global sources and sinks of N2O. Their findings show N2O emissions are

Nitric oxide a possible treatment for COVID-19, study finds — ScienceDaily

Researchers at Uppsala University have found that an effective way of treating the coronavirus behind the 2003 SARS epidemic also works on the closely related SARS-CoV-2 virus, the culprit in the ongoing COVID-19 pandemic. The substance concerned is nitric oxide (NO), a compound with antiviral properties that is produced by the body itself. The study is published in the journal Redox Biology.

“To our knowledge, nitric oxide is the only substance shown so far to have a direct effect on SARS-CoV-2,” says Åke Lundkvist, a professor at Uppsala University, who led the study.

Since there is still no effective cure for COVID-19, the main emphasis in the treatments tested has been on relieving symptoms. This can shorten hospital stays and reduce mortality. To date, however, it has not been possible to prove that any of these treatments has affected the actual virus behind the infection.

Nitric oxide (NO) is

PSI scientists have gained a fundamental understanding of a highly promising material that could be suited to future data storage applications. Their experiments with strontium-iridium oxide, Sr2IrO4, investigated both the magnetic and electronic properties of the material as a thin film. They also analyzed how these properties can be systematically controlled by manipulating the films. This study was made possible by sophisticated X-ray scattering, a technology where PSI researchers are amongst the world experts. The results are published today in the journal Proceedings of the National Academy of Sciences.


In their quest for the magnetic data storage of the future, researchers are looking for suitable materials with properties that can be customized as
