Supercapacitors to replace batteries!

A recent article highlights the work of scientists at Vanderbilt University who claim power can be delivered from a car's chassis rather than the costly and weighty batteries normally associated with a hybrid or electric car.

Collaboration to provide new insights into Advanced Materials

The understanding of advanced materials and how they perform under different conditions will be enhanced thanks to a new research collaboration between the Science & Technology Facilities Council (STFC) and the National Physical Laboratory (NPL).


Progress made in search for lead-free ferropiezoelectrics

Researchers at Instituto de Ciencia de Materiales de Madrid (ICMM) and CIMAV (Chihuahua, Mexico) have carried out a synchrotron powder diffraction experiment, designed to shed light on the controversial problem of the crystal structure of 
0.96(Bi0.5Na0.5) TiO3-0.04BaTiO3. 

The investigated material is a key component of the current international search for lead-free ferropiezoelectrics.

Development of a Thick Film PZT Foil Sensor for Use in Structural Health Monitoring Applications

Copyright: Cranfield University

Acoustic Emission (AE) monitoring is a technique of growing interest in the field of non-destructive testing (NDT). The use of AE devices to monitor the health of structural components is currently limited by the cost of AE equipment, which prohibits the permanent placement of AE devices on structures for the purposes of continuous monitoring and the monitoring of areas with limited access. Micro-electromechanical systems (MEMS) can provide solutions to these issues. The manufacture of a lead zirconate titanate (PZT) film 4.4μm thick on a 110μm thick titanium foil substrate for use as an AE sensor is presented. The thick film sensor is benchmarked against commercially available AE sensors in static and dynamic monitoring applications. The thick film AE device is found to perform well in the detection of AE in static applications. A low signal to noise ratio is found to prohibit the detection of AE in a dynamic application.

EC publishes draft work programmes

In advance of the official call, the European Commission has published the draft work programmes. These papers are being made public just before the adoption process of the work programmes to provide potential participants with the currently expected main lines of the work programmes 2014-2015. They are working documents not yet endorsed by the Commission and their contents do not in any way prejudge the final decision of the Commission.


Smart materials develop into genius materials

Apparently NASA are developing genius materials on-board the International Space Station. They describe them as self-assembling smart materials. However, they describe smart materials as engineered rather than those adapted from nature. (From Smart Materials Group).


Lead-free Ba0.9Ca0.1Ti0.9Zr0.1O3 piezoelectric ceramics processed below 1300 °C

The Instituto de Ciencia de Materiales de Madrid (ICMM) in collaboration with partners from Mexico have processed lead-free ceramics with high piezoelectric sensitivity at temperatures below 1300 ºC. This low thermal budget processing will facilitate commercialisation of the lead-free piezoelectrics.
