Leigh Canham is a physicist who specializes in porous silicon and has set up a company called pSiMedica in Malvern to exploit the material. 3. Kovalev and his team were studying the optical properties of porous silicon, a sponge-like material. 4. Other labs have created explosions in porous silicon wafers, he said. 5. Porous silicon has a layer of hydrogen just one atom thick covering its surface. 6. The violent explosion was caused by scientists in a lab in Germany whilst studying porous silicon. 7. The team applied an oxidising chemical, gadolinium nitrate, to a porous silicon wafer. |
