A new electrochemical approach could reduce ocean acidity and remove carbon in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...

New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...

Nanodevices can produce energy from evaporating tap or seawater

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the Earth drives evaporative processes. Since 2017, researchers have been working ...

Saturday Citations: New hope for rumbly guts; 'alien' signal turns out to be terrestrial and boring. Plus: A cool video

I've seen things you people wouldn't believe. Rodents eating herbal remedies. I watched a truck mistaken for an alien message. All those moments will be lost in time, like the Upper West Side under land subsidence.

Nearly 2 billion people globally at risk from land subsidence

Land subsidence is a geohazard caused by the sudden or gradual settling (years to decades) of the land surface due to the removal of subsurface material. This can be due to a variety of factors, both natural (such as earthquakes, ...

Extracting high-quality magnesium sulphate from seawater desalination brine

Given that mining to extract high-grade mineral ores is wastefully energy intensive, exhaustible, and bad for the environment, scientists have been scouting for alternatives. A group of Korean researchers, led by Professor ...

Drinking water from the sea: Electrochemically mediated seawater desalination in microfluidic systems

(Phys.org) —A new method for the desalination of sea water has been reported by a team of American and German researchers in the journal Angewandte Chemie. In contrast to conventional methods, this technique consumes little ...

A more affordable, accessible material for seawater desalination

There are vast quantities of seawater available; drinking water, on the other hand, is in scarce supply. Desalination plants can convert seawater to drinking water. Yet these plants require pipelines made of a special kind ...
