To help you stay up-to-date with the latest achievements from the chemical engineering research community here is our monthly instalment with some of the latest stories.
September’s five stories of amazing chemical engineering research and innovation are:
The Popeye effect – powered by spinach
Popeye was right; we can be powered by spinach! Researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight, using a simple membrane extract from spinach leaves. The article, publish in the journal Nature Communications, demonstrates the unique combination of a man-made BPEC cell and plant membranes, which absorb sunlight and convert it into a flow of electrons highly efficiently. The team hope that this paves the way for the development of new technologies for the creation of clean fuels from renewable sources. The raw material of the device is water, and its products are electric current, hydrogen and oxygen.
The ChemEng365 campaign concluded at the end of May when Geoff’s term as president ended. But of course, all the amazing chemical engineering research and innovation still goes on. So, it seems only fitting to give you a research round-up on all things chemical and process engineering for the month of June – just in case you missed anything!
Injectable hydrogel could help wounds heal more quickly
I’ve always been intrigued by buildings with ‘living’ or ‘green roofs’. It’s easy to forget they are not a modern invention. Places like Skara Brae Prehistoric Village in Scotland date back more than 5,000 years and have distinctive roofs using the benefits provided by nature.
Green roofs today are sold on the back of their environmental and economic benefits such as insulation and cooling properties, ability to significantly reduce rainwater run-off from roofs, and their value in promoting biodiversity and habitat in built-up areas. They look very impressive and distinctive too.
I think they are a useful reminder that buildings need to connect more with their environment for good reasons like reducing heating costs and greenhouse gas emissions. In the UK, around 13 per cent of greenhouse gas emissions come from the residential sector.
Have you noticed how often nature inspires technological advancements? It’s something that chemical engineers are very adept at and have made a series of recent discoveries that have great potential.
Research by Newcastle University in the UK found that nickel nanoparticles on the exoskeletons of Sea Urchin larvae gave them the ability to convert CO2 to calcium carbonate. The finding has the potential to help mitigate climate change.
