Chemical vapour deposition at speed

Synthesis and screening of thin film samples on glass may become faster using modified atmospheric pressure chemical vapour deposition equipment developed at University College London (UCL), UK. This is combined with rapid automated analysis of each cell to identify new and suitable phases.

Surface solution for writing nanodata

A carbon nanotube (CNT) probe tip, with silicon oxide outer layer for wear resistance, could enable ultrahigh density data storage. The ‘nanopencil’ can write bit sizes as small as 6.8nm onto ferroelectric films, while the silicon oxide makes it less prone to bending or buckling.

Strengthening tailored composites

The mechanical properties of lightweight composites that are made using tailored fibre placement (TFP) technology could be improved using a new online design tool, say scientists in Germany. The software maps out the concentrated stress areas of the base materials

Implantable blood pressure sensor

UK researchers are exploiting surface acoustic wave (SAW) technology to create a wireless and implantable blood pressure sensor. Scientists at Imperial College London, UK, believe this is the first implantable SAW device.

Bomb-proof concrete

A high performance concrete that is designed to reduce the impact of bomb blasts is being investigated by engineers at the University of Liverpool, UK. Steel fibres reinforce the material.
