The team, from the University of Pittsburgh‘s Swanson School of Engineering, US, have developed a computational model which has allowed them to design a new material. The material has the ability reconfigure its shape and move using its own internally generated power. This ability to change was seen as a catalyst for the development of a soft robot.
This research, undertaken by Dr Anna C. Balazs, Professor of Chemical and Petroleum Engineering and Dr Olga Kuksenok, Research Associate Professor, uses a single-celled organism, Euglena mutabilis, as a model. E. mutabilis is able to process energy to expand and contract its shape. This results in movement.
Many people won’t look beyond jewelry and coinage for the most important usage of precious metals, but chemical engineers know that precious metals like gold, silver, platinum, palladium, rhodium, ruthenium, iridium and osmium have many more valuable uses.
Solar and other fuel cells, batteries, electronics, drugs, after shaves, bandages and even traditional photography have some reliance on precious metals.
Of particular interest to chemical engineers are their uses as chemical catalysts. But, being precious, chemical reactions that require large volumes of the metals are naturally going to be expensive and unsustainable.
One of the solutions is to use computational modeling below the nanoscale level to design more efficient and affordable catalysts from gold. And a transatlantic alliance of three universities have collaborated to achieve just that.
