Energy-Efficient AI: New Hardware Could Slash Computing Power Needs by 1000x

Carbon capturing hydrates created in Vaibhav Bahadur's lab.

Team Develops Fastest Carbon Storage Tech Without Harmful Chemicals

A simple, compact system first collects moisture from the air (left) and then releases the trapped liquid (right) when heated, which results in potable water.

Small, adsorbent ‘fins’ collect humidity rather than swim through water

Chinese reactor mineralizes CO2 with help of coal waste

Engineered yeast-containing hydrogel capsules could be used to remove lead from contaminated water rapidly and inexpensively. The work, from MIT and Georgia Tech researchers, could be especially useful in low-income areas with high lead contamination.

Repurposed beer yeast may offer a cost-effective way to remove lead from water

The conversion was achieved by simply removing two fluorine atoms from 1,2-difluoroalkene derivatives

Converting PFAS “forever chemicals” into valuable compounds

New technology converts a component of natural gas, methane (left), to methanol (right), using the P450BM3 enzyme (middle, grey) with a decoy molecule (middle, colored). This method can be a cheap and effective mean of reducing the carbon footprint of natural gas.

New technology for dramatic reduction of smelly air

UVB has many uses today but requires inefficient and toxic sources to produce. A collaborative effort involving Kyushu University and Johannes Gutenberg University Mainz developed a system where blue LED light is upconverted to UVB light. Moreover, the system uses only organic materials, opening the door for a more sustainable and ecofriendly method of generating UVB light.
