Embedding sensors using sound

Researchers in the UK have used ultrasonic consolidation (UC) to embed active and passive fibres, including optical sensors, into aluminium foils. This technique could be exploited in aeroplane wings.

Algae for bone grafts

Synthetic bone fillers derived from mineralised marine red algae could transform grafting procedures for broken bones, according to scientists at Queen’s University Belfast, UK.

Laminating tile façades

A polymer lamination system for ventilated tile façades improves integrity as well as resistance to tearing, water and UV, say researchers in Spain. They add that the film is faster and cheaper to apply than using traditional wet-chemistry methods.

‘Short circuiting’ alloy design

Developing TRIP steel, stainless steel and other advanced alloys may become faster using a novel genetic algorithm-based thermokinetic computer model.
In vivo images for a control (a) and tumor (b) device three days after being implanted. Superimposed over the device is a pseudo-colourised map of the transverse relaxation time (T2) within the device (colour bar on the left). The T2 of the sample device is lower than the control device, indicating the presence of human chorionic gonadotrophic at the tumor site

Continuous cancer monitoring in vivo

Non-invasive, continuous, in vivo monitoring at the site of cancerous tumours may eventually be possible thanks to research at MIT, USA. Scientists are looking into what they say is the first implantable device that can fulfil this function, using superparamagnetic iron oxide nanoparticles.
