Entries are now open for the Unilever Young Entrepreneurs Awards, supporting and celebrating inspirational young people from all over the world who have initiatives, products or services that tackle the planet’s biggest sustainability challenges.
Scientists from the Universities of Cambridge and Bristol have found a way to create plastic semiconductor nanostructures that absorb light and transport its energy 20 times further than has been previously observed, paving the way for more flexible and more efficient solar cells and photodetectors.
The University has published its Environmental Sustainability Report 2017, setting out its progress over the past 12 months, including key achievements and where there is room for improvement.
Researchers have shown that certain superconductors – materials that carry electrical current with zero resistance at very low temperatures – can also carry currents of ‘spin’. The successful combination of superconductivity and spin could lead to a revolution in high-performance computing, by dramatically reducing energy consumption.
A simple potassium solution could boost the efficiency of next-generation solar cells, by enabling them to convert more sunlight into electricity.
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.
What connects a series of volcanic eruptions and severe summer cooling with a century of pandemics, human migration and the rise and fall of civilisations? Tree rings, says Ulf Büntgen, who leads Cambridge’s first dedicated tree-ring laboratory in the Department of Geography.
Truffles are one of the world’s most expensive ingredients, and also one of the most mysterious. Now, with the help of a 170-year-old ‘living laboratory’, and a dog called Lucy, researchers hope to unearth new understanding of the secret life of these underground delicacies.
