Encapsulation as a method for preventing degradation in Li-air batteries

Lithium-air batteries were thought promising in the 1970s as a potential power source for electric vehicles, offering energy densities that rival gasoline and significantly surpass conventional lithium-ion batteries. However, scientists over the last few decades have been unable to overcome challenges to practical application of this technology, including reversible charging and low cyclability that results […]

Synthesis too slow? Let this robot do it.

Researchers in the lab of Bradley Pentelute, MIT professor of chemistry, have invented a fully automated fast-flow instrument that can synthesize peptide-nucleic acids in a single shot. By automating the process of synthesizing CPP-conjugated peptide-nucleic acids (PPNAs) using the robot dubbed “Tiny Tides” by the research team, typical PPNA synthesis time was reduced from multiple […]

Could acid-neutralizing life-forms make habitable pockets in Venus’ clouds?

It’s hard to imagine a more inhospitable world than our closest planetary neighbor. With an atmosphere thick with carbon dioxide, and a surface hot enough to melt lead, Venus is a scorched and suffocating wasteland where life as we know it could not survive. The planet’s clouds are similarly hostile, blanketing the planet in droplets […]
