Converting CO2 to valuable resources with the help of nanoparticles

An international research team has used nanoparticles to convert carbon dioxide into valuable raw materials. Scientists have adopted the principle from enzymes that produce complex molecules in multi-step reactions. The team transferred this mechanism to metallic nanoparticles, also known as nanozymes. The chemists used carbon dioxide to produce ethanol and propanol, which are common raw materials for the chemical industry.

Longest coral reef survey to date reveals major changes in Australia's Great Barrier Reef

An in-depth look at Australia's Great Barrier Reef over the past 91 years concludes that since 1928 intertidal communities have experienced major phase-shifts as a result of local and global environmental change, leaving few signs that reefs will return to their initial state in the near future. The long-term implications of these changes highlight the importance of avoiding phase shifts in coral reefs which may take many decades to repair, if at all.

First fully rechargeable carbon dioxide battery with carbon neutrality

Researchers are the first to show that lithium-carbon dioxide batteries can be designed to operate in a fully rechargeable manner, and they have successfully tested a lithium-carbon dioxide battery prototype running up to 500 consecutive cycles of charge/recharge processes.

Potentially large economic impacts of climate change can be avoided by human actions

A study estimates global-scale, multi-sectoral economic impacts of climate change, and suggests that a plausible range of decisions and actions by humans can determine the scale of the economic impacts, even if the uncertainty in the climate response to increased greenhouse gas concentration is considered. These actions include reductions of greenhouse gas emissions and improvement of socioeconomic conditions. This study highlights the importance of societal changes and the current generation's responsibility for the future.
