This November, Computing and CRN will once again be hosting the Women in Tech Festival Global with content that doesn't shy away from the harsh realities of being a woman within the tech industry across the world. A NEW carbon capture process has been developed that turns carbon dioxide gas into solid carbon that is easier to store. At Columbia University’s Lamont-Doherty Earth Observatory, David Goldberg is on the forefront of developing technologies with the ability to capture CO2 and turn it into stone. So far, these methods have proven to be extremely costly and have also raised some potential environmental concerns over the safe storage of CO2 underground. "By using liquid metals as a catalyst, we've shown it's possible to turn the gas back into carbon at room temperature, in a process that's efficient and scalable. Our global membership community includes people from a range of disciplines who have an interest in and/or relevant experience in chemical engineering and our membership rates range from a low single fee for students to annual subscriptions for professional Members. Next, the researchers piped CO2 into the beaker and passed a small amount of electricity into the wire. The new catalytic process converts CO2 gas to flakes of solid carbon.

"A side benefit of the process is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles," said Dorna Esrafilzadeh, a chemist at RMIT University, and the lead author of the study paper.

Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Below are the four latest issues. Critical infrastructure and systems such as GPS rely on time-keeping mechanisms that are far too easily subverted or prone to error, Latest Computing Delta research finds the leaders pulling away from the competition.

The detailed findings of the study are published in the journal Nature Communications. Carbon dioxide is bubbled into a container filled with an electrolyte liquid and a small amount of the liquid metal, which is then charged with an electrical current. According to researchers, the new technique uses a liquid alloy to turn CO2 into carbon particles, thus providing an alternate pathway for removing the harmful greenhouse gas from our environment. In typical CO2 capture processes, the CO2 gas is pressurised to a liquid, which is then transported to a suitable site and stored underground.

The CO 2 slowly reacts with the cerium in the presence of electricity and converts into solid flakes of carbon, which detach from the liquid metal surface. "To date, CO2 has only been converted into a solid at extremely high temperatures, making it industrially unviable," says RMIT physical chemist Torben Daeneke. The solid carbon is produced by the electrocatalyst when low potentials are used, but at higher potentials the dominant product is CO gas, which could be used to produce industrial chemicals and synthetic fuels. When they inserted a wire into the liquid metal, it resulted in a reaction between some of the cerium with oxygen from the air in the beaker, creating a thin layer of cerium oxide.
