Eight Chinese students in the UK have made it to the finals of the Mayor of London's International Student Innovation Awards 2016.
An everlasting cooling system, which ensures that medical vaccines reach their destinations undamaged, and a device which stops the tremors in Parkinson's disease sufferers are just two of the inventions they have submitted.
The International Student Innovation Awards were set up to highlight the work of the London's international students and also to provide financial assistance to help students take their innovations to the next stage of development.
Hundreds of entries, from 49 different countries and 17 London universities, have been received and have now been whittled down to a final shortlist.
An event crowning 'London's most innovative international student' - who will receive £10,000 to kick-start their business - will be held on Nov 2 at Central Saint Martins, Granary Square.
The awards were devised by London & Partners, the Mayor's official promotional company, and are supported by the UK Government's Education is GREAT campaign, the British Council, Cambridge English, IDP Education and The PIE.
The Mayor of London, Sadiq Khan, said: "The incredible range of talent on show in these awards celebrates the best of the capital and clearly demonstrates that London is open to talent and ideas from across the globe. We need to do all we can to ensure that London remains the best and most welcoming destination for international students."
