• A building material that lives and stores carbon

  The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms – "such as the ability to bind CO₂ from the air by means of photosynthesis," says Mark Tibbitt, Professor of Macromolecular Engineering at ETH Zurich.

  An interdisciplinary research team led by Tibbitt has now turned this vision into reality: it has stably incorporated photosynthetic bacteria – known as cyanobacteria – into a printable gel and developed a material that is alive, grows and actively removes carbon from the air. The researchers recently presented their "photosynthetic living material" in a study in the journal Nature Communications.

  Abstract: Among the most active areas of chemistry research today is that of carbon dioxide utilization: an area of research that was viewed as futile and commercially impractical not so long ago due to the energetic stability of the CO₂ molecule. The breakthroughs that largely began in earnest in the 1990s have accelerated and now make up a diverse and plentiful portfolio of technological and scientific advances and commercialized technologies. Here, “The CO₂ Tree” is presented as a tool to illustrate the breadth of potential products from CO₂ utilization and to communicate the potential of these chemical breakthroughs to address the greatest challenge that society faces today: climate change. It is intended to be useful for scientists, engineers, legislators, advocates, industrial decision-makers, policy makers, and the general public to know what is already possible today and what may be in the near future.

  A new technique that uses soundwaves to separate materials for recycling could help prevent potentially harmful chemicals leaching into the environment.  Researchers at the University of Leicester have achieved a major milestone in fuel cell recycling, advancing techniques to efficiently separate valuable catalyst materials and fluorinated polymer membranes (PFAS) from catalyst-coated membranes (CCMs).

  A team led by Rice University bioscientist  Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen. The findings, published in Cell last month, could enable new developments in clean energy and industrial biotechnology.

  The Office of Electricity’s (OE’s) Microgrid Program recently concluded a scoping study of the campus microgrid at the University of Illinois Urbana-Champaign with a focus on integrating a Small Modular Reactor (SMR) into the generation mix. SMRs are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit (about one-third the size of traditional nuclear power reactors). The nuclear power industry is rapidly innovating to meet the energy demands of a decarbonizing world.  Advanced technologies, such as SMRs, can be deployed as electricity producers on the grid or in tightly integrated energy systems, such as campus microgrids, to provide reliable, dispatchable carbon-free power.
