Australian research voyage to investigate how life in the Southern Ocean captures and stores carbon from the atmosphere — ScienceDaily

A fleet of new-generation, deep-diving ocean robots will be deployed in the Southern Ocean, in a major study of how marine life acts as a handbrake on global warming.

The automated probes will be looking for ‘marine snow’, which is the name given to the shower of dead algae and carbon-rich organic particles that sinks from upper waters to the deep ocean.

Sailing from Hobart on Friday, twenty researchers aboard CSIRO’s RV Investigator hope to capture the most detailed picture yet of how marine life in the Southern Ocean captures and stores carbon from the atmosphere.

Voyage Chief Scientist, Professor Philip Boyd, from AAPP and IMAS, said it would be the first voyage of its kind to combine ship-board observations, deep-diving robots, automated ocean gliders and satellite measurements.

“The microscopic algae in the ocean are responsible for removing carbon dioxide from the atmosphere as much as the forests on land

Storing carbon through tree planting, preservation costs more than researchers thought

[email protected]_84

Dec. 1 (UPI) — Planting trees and protecting forests are two of the myriad strategies for keeping carbon out of the atmosphere.

Of all the options, they’re considered the most eco-friendly, or greenest, but new research suggests planting and protecting trees does come with costs — and those costs are quite a bit larger than has been previously estimated.

According to a new study, published Tuesday in the journal Nature Communications, planting trees and conserving forests could reduce carbon dioxide emissions by as much 6 gigatons a year between 2025 and 2055.

Researchers calculated the reductions would come with an annual price tag of $393 billion.

“There is a significant amount of carbon that can be sequestered through forests, but these costs aren’t zero,” study co-author Brent Sohngen, professor of environmental economics at the Ohio State University, said in a news release.

According to Sohngen and his colleagues, previous studies

Astronomers discover carbon monoxide gas flowing from distant star system

[email protected]_84

Nov. 30 (UPI) — Scientists have discovered rapid outflow of carbon dioxide emanating from a star system located 400 light-years away.

Astronomers suggest this unique stage of a planetary system could offer scientists fresh insights into the birth and development of our own solar system.

The discovery is scheduled to be presented next week at the Five Years After HL Tau virtual conference. The research has also been accepted for publication in the journal Monthly Notices of the Royal Astronomical Society.

The outflow of carbon dioxide was first spotted during the survey of young “class III” stars by the Atacama Large Millimetre/submillimetre Array in Chile. Some of these young, low-mass stars host debris rings created by the collision of comets, asteroids and planetesimals.

Because the debris from these collisions absorb and reradiate the energy of their host star, these rings can be detected by ALMA.

Around one star, named “NO

Detecting bacteria with fluorescent nanosensors: Luminous carbon nanotubes detect pathogens – and are quick and easy to use –

[email protected]_84

Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods. A team headed by Professor Sebastian Kruß, formerly at Universität Göttingen, now at Ruhr-Universität Bochum (RUB), describes the results in the journal Nature Communications, published online on 25 November 2020.

Traditional methods of detecting bacteria require tissue samples to be taken and analysed. Sebastian Kruß and his team hope to eliminate the need to take samples by using tiny optical sensors to visualise pathogens directly at the site of infection.

Fluorescence changes in the presence of bacterial molecules

The sensors are based on modified carbon nanotubes with a diameter of less than one nanometre. If they are irradiated with visible light, they emit light in the near-infrared range (wavelength of 1,000 nanometres and more), which is

South Korean scientists find way to extract carbon emissions from exhaust gas

[email protected]_84

Nov. 23 (UPI) — South Korean researchers say they have developed technology that can draw out carbon dioxide from industrial emissions and convert the climate-warming gas into calcium carbonate, which then can be adapted for different uses.

Koh Dong-yeun and his team at the Korea Advanced Institute of Science and Technology, KAIST, said they have developed a device to convert carbon dioxide into solid materials, which can be used to make cement and other materials, Aju Daily and Yonhap reported Monday.

The statement from KAIST comes two months after Koh and his team published their findings to the online site of ACS Sustainable Chemistry and Engineering, a peer-reviewed journal.

“The technology helps power plants, steel mills and cement makers, which emit a lot of greenhouse gas, to increase their competitiveness by reducing emission and recycling resources,” Koh said, according to Aju Daily.

The scientists said an ultrapermeable membrane is the

Hydrogen peroxide (H2O2) has found many applications in the modern industry, including acting as a green oxidant in disinfectants, bleaching agents, sanitizing agents, chemical synthesis, and even as a potential energy carrier. A new catalyst, which enables on-site generation of H2O2 has been developed. It has gained much attention in both academia and industry as a quick, simple and inexpensive method to produce H2O2, which is in constant demand.


A research team, led by Professor Jong-Beom Baek in the School of Energy and Chemical Engineering at UNIST has developed a carbon-based high-efficiency electrochemical catalyst for use to produce H2O2. Because it is carbon-based, it is inexpensive and requires no complicated process, and thus allows for on-site production of H2O2.

Which photophysical properties does carbyne have? This was the subject of research carried out by scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Alberta, Canada, and the Ecole Polytechnique Fédérale de Lausanne in Switzerland, which has led to a greater understanding of the properties of this unusual form of carbon. Their findings have now been published in the latest edition of the journal Nature Communications.

‘Carbon has a very special status in the periodic table of the elements and forms the basis for all forms of life due to the extremely large number of chemical compounds it can form,’ explains Prof. Dr. Dirk M. Guldi at the Chair of Physical Chemistry I at FAU. ‘The most well-known examples are three-dimensional graphite and diamond. However, two-dimensional graphene, one-dimensional nanotubes and zero-dimensional nanodots also open up new opportunities for electronics applications in the future.’
