Gas

Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels.

Australian scientists say they've made a "eureka moment" breakthrough in gas separation and storage that could radically reduce energy use in the petrochemical industry, while making hydrogen much easier and safer to store and transport in a powder.

Astronomers have discovered bizarre “blue blobs” in space. These blobs are clusters of young, blue stars that are isolated from any parent galaxy, suggesting they formed from a galactic “belly flop.”

The European Union is currently pumping about US$118 million a day into Russia due to its dependence on natural gas. The new REPowerEU plan is a chance to cut that figure down fast, and accelerate the transition to green energy in the process.

Bubbles aren’t known for their long lifespans, usually only giving a few seconds of childlike joy before they pop. A team of French scientists has developed a new way to make bubbles last longer, with the record holder surviving for well over a year.

Infrared spectrometers are expensive and powerful instruments scientists use to analyze the chemical makeup of a sample, and a new research project has made a breakthrough that miniaturizes this technology so much it can be packed into a smartphone.

Scientists have recreated in the lab some of the wild weather that might be found on Jupiter and Saturn. Using extremely high pressures and laser shock waves, the researchers produced helium rain which has been hypothesized to fall on these planets.

The NSW Government has funded Australia's first dual-fuel-capable power plant to the tune of US$64 million. The Tallawarra B project will initially run on natural gas, but will be gradually upgraded to burn green hydrogen over coming decades.

Although there already are devices that can detect harmful gases, most of them aren't particularly portable or simple to use. An experimental new tool, however, is about the size of a hypodermic needle – and it could be utilized by anyone, anywhere.

In September 2020, astronomers announced the discovery of phosphine in the atmosphere of Venus, a possible sign of life. But a new study has found that a different gas could explain the signature – one that's more common and doesn’t indicate life.

Engineers at the National University of Singapore have developed a new way to convert natural gas into a solid form, enabling safer and easier storage and transport. The process can be done in just 15 minutes using a low-toxicity mixture.

Scientists have fashioned graphene into microscopic balloons they say can distinguish between different kinds of noble gases, by measuring how long the gas takes to escape through tiny perforations in the surface of the balloons.
