blow-moulded PET foam

Blow-moulding PET foam

Materials World magazine
A foamed PET blow-moulding process that creates lighter weight bottles has been developed, according to polymer researchers in the USA. They say the technique creates recyclable, decorative and textured PET containers.

Lining up flexible electronics

Materials World magazine
Scientists in the USA have developed a dual-tone photo-resist for novel multiwavelength photolithography. This is said to overcome the problems of poor registration and alignment when patterning multiple layers on polymers and metal foils for flexible electronics.

Sourcing the stresses in composites

Materials World magazine
Researchers at the University of Southampton, UK, are working to create a more coherent calibration strategy for thermoelastic stress analysis (TSA) to better characterise and engineer complex composite components. The aim is to eventually create non-contact inspection tools and systems, enabling industry to obtain real-time measurements.

Raising the bar in non-volatile memories?

Materials World magazine
European researchers have engineered a Schottky zinc oxide diode/selector to help pave the way for crossbar architecture. Crossbar may eventually replace flash technology in non-volatile memory devices.
hydraulic lime mortar

Home and dry – lime mortar

Materials World magazine
A low-energy drying technique for aggregates in hydraulic lime mortar has been developed by a UK consortium. The research aims to make lime mortars commercially viable for new build projects, as they have the ability to make bricks easier to recycle and contain around 45% less embodied CO2 than cement mortars.
