MIT engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets. —Michael Strano.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential. 2021.02.015.

Polymer-dipped carbon nanotube catalysts equal or outperform platinum catalysts in fuel cells; potential for significant cost reduction

Green Car Congress

Illustration of charge transfer process and oxygen reduction reaction on PDDA-CNT [poly(diallyldimethylammonium chloride)-carbon nanotube]. The team led by Liming Dai, a professor of chemical engineering, is certain they can boost the power output and maintain the other advantages by matching the best nanotube layout and type of polymer.

ExxonMobil, UC Berkeley, Berkeley Lab develop new MOF for carbon capture and steam regeneration

Green Car Congress

Scientists from ExxonMobil, University of California, Berkeley and Lawrence Berkeley National Laboratory have developed a new material that could capture more than 90% of CO 2 emitted from industrial sources using low-temperature steam, requiring less energy for the overall carbon capture process.

New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.
