Concrete and steel have allowed us to build some of the most impressive structures on Earth . The industries responsible for manufacturing them also account for nearlyone - tenthof the human race ’s carbon emission . As both the menace of clime change and our need for urban ontogeny continue to rise , scientist at the University of Cambridge ’s Department of Engineering are looking into a possible alternative : artificial clappers and eggshells .
AsGeekreports , the squad , lead by Michelle Oyen , is using biomimetics — the field of building materials base on element from nature — to quicken two top-notch - strong materials that come about organically . For their weight , bones areremarkably hard . A comparable prevention of steel weighs four to five time as much as a human bone , making off-white the stronger stuff troy ounce - for - apothecaries' ounce . shell are also subject of supporting considerablyheavy loadsdespite their thin structure .
To renovate these elements in the lab , Oyen and her squad are templating layers of minerals onto collagen , the most abundant animal protein on Earth . The mineral components make the construction slopped , while the protein serve it withstand breakage . The artificial bone and eggshell materials are made from different combining of minerals and protein , and the squad recently discovered that the two material form perpendicularly to one another . This may open up the door for acquire a wicket hybrid anatomical structure that ’s solid than either component individually .
In contrast to all the work that locomote into blade production , these material can be made at room temperature and involve much less energy to manufacture . The technology could potentially be used to make medical implants , or it could be scale up and incorporated into small - carbon expression projects .
" All of our live building standard have been design with concrete and steel in thinker , " Oyen told the University of Cambridge . " Constructing building out of entirely new materials would mean completely rethinking the whole industry . But if you want to do something really transformative to bring down carbon emanation , then I think that ’s what we have to do . "
She ’s presently looking into using non - animal – derived or synthetic proteins or polymers as a possible replacement for the collagen in her structures . mimic theself - healing propertiesof bone in construction cloth is also something engineers are hop to achieve down the route .
