First snapshots of CO2 molecules trapped in MOFs shed new light on carbon capture

Green Car Congress

It has high commercial potential because it’s very cheap and easy to synthesize. Cryo-EM not only let the team make super-sharp images with minimal damage to the particles, but it also kept the CO 2 gas from escaping while its picture was being taken. It’s already being used to capture and store toxic gases.

Much of the motivation behind building new rockets or developing colonies on Mars is wrapped up in the rhetoric of our warming planet being something to escape from. Nonprofits are already using cheap sensors to pinpoint heat islands in cities, or neighborhoods where air pollution disproportionately affects communities of color.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

Green Car Congress

Current carbon capture technology uses caustic amine-based solvents to separate CO 2 from the flue gas escaping a power plant’s smokestacks. These permeable silicone beads could be a “sliced-bread” breakthrough for CO 2 capture—efficient, easy-to-handle, minimal waste, and cheap to make. —Vericella et al.

Optimizing Fume Control for Robotic Welding

Green Car Congress

Exhaust systems are cheap to install, but generally not the best option for the large volumes of fumes produced by robotic welding applications. Clean(er) outdoor air must then be returned back to the facility to avoid negative pressure build up. Size Filters to CFM. CFM drives filter sizing in addition to energy consumption.
