New porous coordination polymer captures CO2, converts it to useful organic materials

Green Car Congress

One possible way to counteract rising global CO 2 emissions is to capture and sequester carbon from the atmosphere, but current methods are highly energy intensive. The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. —Wu et al.

Li-ion sulfur polymer battery shows high energy density as well as safety

Green Car Congress

A team from the University of Rome Sapienza has developed a rechargeable lithium-ion polymer battery based on the combination of a high capacity sulfur-carbon cathode, nanostructured Li x Sn-C anode and polysulfide-added PEO-based gel membrane. Moreover, the addition of a dissolved polysulfide (i.e.
