As they age, steel and concrete structures often need to be retrofitted. One such way of strengthening is with Carbon Fibre Reinforced Polymer – or ‘CFRP’ – laminates. For certain applications, however, this can be a difficult and time-consuming process, and the resulting laminates are prone to debonding. In his research, Dr Abheetha Peiris at the University of Kentucky developed a new type of strengthening in the form of CFRP strip and rod panels. The panels can slot together seamlessly – making them less prone to failure, and far easier to assemble. Through a series of experiments and field applications, he revealed how the new method can be applied for retrofitting both steel and concrete structures.
Satellites are vital to modern civilization, powering the GPS in our phones, enabling long-range communication, and giving us insights into Earth’s climate and the universe beyond. We now launch thousands of new satellites into space each year, dramatically increasing the risk of collisions. Such satellite collisions create debris that can damage more satellites. Thomas Kleinig and his colleagues are developing and testing a new approach to avoid collisions by exploiting a unique property of the thin atmosphere that satellites travel through.
Organic molecules dissolved in rivers, lakes, seas and oceans are essential to plant and animal life. Some of these molecules are also degraded and enter a complex cycle of carbon, nitrogen and sulphur containing compounds. Surprisingly, scientists currently have a limited understanding of the fate of these molecules. Dr Daisuke Minakata and his colleagues from Michigan Technological University are involved in an ambitious programme to overcome this critical knowledge gap.
The COVID-19 pandemic forced many universities to deliver their courses online, exposing the limitations of remote learning strategies. Dr Barrett Caldwell and his team at Purdue University devised a new approach that could help to improve online courses in different engineering subjects. The approach builds on his experience while teaching and developing the ‘Perspectives on Systems Engineering’ course, which is part of the curriculum for the Systems Engineering program at Purdue University.
