Seabed mining, arctic exploration, and sourcing underdeveloped countries, such as Afghanistan, will help secure future minerals supplies as countries face the squeeze from resource-rich developing nations. That was the message delivered by experts from the British Geological Survey (BGS) at the event, ‘Meeting the mineral commodity challenge’ event, held in London, UK, on 14 October 2008.
Finex 2008, held from 23-24 September 2008, highlighted technological advances in exploration and the financial support that has led to London, UK, regaining its role as one of the world’s great mining capitals. The skills shortage in the mining industry was also addressed.
Synthetic fused silica (quartz) based microfluidic devices can now be etched deeper and for longer using new photoresist layers. This will enable more effective fluid control and chemical analysis in bioscience and medicine.
Graphene films that can be deposited over large areas of a substrate may be possible using modified chemical mechanical polishing, according to scientists in the USA. The material’s perfect 2D crystallographic nature and electrical properties will enable high-speed and flexible circuitry in electronic devices.
