LONDON (Reuters) - Government data show Britain is countering the "brain drain" in science and innovation as entrepreneurial talent that might previously have gone elsewhere moves in.
Here are penpix of a few of the recent newcomers:
Arup Chatterjee developed nanotechnology techniques in India for a decade and then went on to invent nano-metal enhanced paints and coatings and form his company I-Can Nano.
His technology gives special characteristics to a range of surfaces, making them resistant to ultraviolet rays, water and fungal growth.
The entire stadium and complex for the Commonwealth Games in Delhi 2010 has been painted with I-Can Nano paints.
Chaterjee has now set up his European headquarters in Britain and secured funding to grow the business, eying the European market and beyond.
Compound Photonics is a company which grew out of a lab in Phoenix in the United States, developing extremely high definition television and cinema screens.
While normal High Definition (HD) has around 1 million pixels to a standard TV screen, theirs has 10 million pixels. And the firm says it has also worked out a way to create 3-D images on screens without the use of 3-D glasses, and yet is still cost effective.
Jonathan Sachs, a co-founder of the firm, says it decided to set up global headquarters in Cambridge, eastern England, because of the access there to the world-class photonics lab at Cambridge University. The firm also secured funding from Create Partners, a fund management company based nearby in eastern England.
Romanian 23-year-old Emi Gal's firm Brainient produces cutting edge software to help media companies to make money from the videos they place on their websites.
Brainient software allows the media companies to add hotspots to any consumer products in their videos with links to where to buy them.
Brainient was selected as a winner of Seedcamp 2009 -- a competition designed to jumpstart the entrepreneurial community in Europe -- and Gal now has global headquarters in London because it offers access to all the large media companies.
South Korean former NASA scientist Jeong Hyun Lee has an environmentally-friendly technology business venture, Plumina, which produces ultra-low energy LED street lights based on a new heat management material which is up to 150 times more conductive to heat than regular copper.
Plumina says its lights can last more than 50,000 hours and are up to 70 percent more efficient than traditional street lighting, which typically lasts 8,000 hours. The firm's heat management material can also be used to build fuel cells and solar panels.
Like Sachs, Lee says he chose Cambridge for its access to the science base. He also says being in Britain is crucial to helping expansion into Europe, Africa, Asia and the Middle East.
