Efficient uptake of uranium(VI) realized by layered manganese thiophosphite intercalated with ammonium

With the rapid development of nuclear power worldwide, the demand for uranium continues to increase. As a consequence, large quantities of uranium-containing wastewater are generated throughout the nuclear fuel cycle as well as during spent fuel reprocessing. Uranium (U) is highly chemical toxic and strongly carcinogenic to the living system. Therefore,...

Researchers zero in on methane released from reservoirs

Methane is a potent greenhouse gas that accounts for about a fifth of today's global warming. In addition to methane emitted from livestock and other agricultural practices, the gas is also spewed from the production, transport, and burning of fossil fuels and the breakdown of organic material. Methane is released into the atmosphere continually. Scientists...

Nickel-catalyzed cross-coupling of aromatic ethers proceeds via a nickelate anion

Metal catalysts are widely used in the production of drugs, dyes, adhesives, and plastics. Researchers have now discovered an intriguing property of nickel as a catalyst: it is able to catalyze the coupling of aromatic hydrocarbons in its anionic form, the nickelate ion. In this form, the two metals, lithium and nickel, work in cooperation in a unique...

NASA releases new dataset of cyanobacteria in over 2,300 lakes in the US

Lakes provide drinking water for people, habitat for plants and wildlife, and a place to fish, boat and swim. But the water can become harmful to humans, animals and the ecosystem when toxic algae called cyanobacteria reach abnormally high levels due to warm, nutrient-rich water conditions.

New research shows scientific agreement on anthropogenic nature of climate change strengthened since 2009

Scientific support for the link between human activity and climate change has strengthened to the extent that there is now near universal agreement. Whereas in 1996, reports hedged statements with phrases such as "the balance of evidence suggests…" (Houston et al 1996), this evolved to "it is extremely likely that human influence has been the dominant...

Long-term greenhouse gas influence on retreating glaciers

Research conducted in the Southern Alps by Te Herenga Waka—Victoria University of Wellington's Dr. Shaun Eaves and others shows greenhouse gases, particularly carbon dioxide, have been integral to the retreat of Aotearoa's glaciers for at least the past 5,000 to 7,000 years, since the mid-Holocene epoch.

Looking out for waterbirds from high above

UNSW's annual waterbird survey—a unique dataset that allows scientists to monitor more than 50 species, and assess the health of rivers and wetlands—kicked off in early October. Even though it's all a little bit different to previous years, due to COVID-19 restrictions, the team has already made interesting observations onboard the small plane that's...
