Flintstone Technologies, an investment group backing Russian scientists who have moved to the UK, has postponed its £19m stock market float due to a technical issue outside the company's control.
Flintstone teamed up with academics from Moscow University to form six new companies, two of which have set up at Begbroke Science Park, north of Oxford.
Hardide is developing a new super-hard wear-resistant coating invented by Prof Lakhotkin, Sergei Alexandrov and Yuri Zhuk.
IntelliKraft is developing a new nanomaterial that could lead to super-longlife batteries and more efficient car engines.
The two companies have been backed by Oxford Technology Venture Capital Trust.
The company is a holding company for CFB, the Isle of Man-based intellectual property group which commercialises technologies in the industrial technology sector, including joint ventures with Russian scientists.
