Empa Innovation Award 2014

This years Empa Innovation Award was given to the Empa laboratories Structural Engineering and Joining Technologies and Corrosion for their innovative R&D on "Shape memory steel as a new prestressing Material for the building industry". The award was officially presented during the Empa Innovation and Technology Forum (ETIF).

Shape memory alloys, or SMAs, possess the ability to return to their original shape after being severely deformed, either spontaneously or following the application of heat. This makes them useful materials, not just for making spectacle frames but also for technical applications such as thermostats, stents and micro-actuators. Other applications in the construction industry are conceivable too, for example in the reinforcement of bridges. If a concrete beam is cast with reinforcing rods made of an SMA material, these can then be “activated” through the application of heat. They attempt to return to their original shape, but because of their concrete sheath they cannot do so, thus exerting a pre-stressing force on the beam. This effect can be used, for example, to pre-stress a complete bridge span. In order to generate the necessary force the SMA rods must simply be heated by passing an electric current through them. This obviates the need for using elaborate tensioning systems and jacket tubes, as used in conventional pre-stressing techniques.

The nickel titanium alloys used to make spectacle frames or stents are not very suitable for use in the construction industry. Iron-based SMA products are much more attractive, since both the raw materials and the processing costs are far cheaper. However, to date one problem has remained a stumbling block: to activate the memory effect the materials currently used must be heated up to 400° C, which for applications involving concrete or mortar, or other heat sensitive materials, is too high. Empa researchers led by Christian Leinenbach of the Joining Technology and Corrosion Laboratory have now succeeded in developing a novel iron-manganese-silicon SMA alloy which is activated at just 160° C, a temperature much more suitable for use with concrete. The material science researchers "designed" a range of virtual alloys using thermodynamic simulations, and then selected the most promising combinations. These were then manufactured in the laboratory and their shape memory characteristics tested, with great success. Several of the new materials met the construction engineers’ requirements, an important milestone on the path to providing economic shape memory steel alloys for industrial applications – in other words, manufacturing them by the ton.

We cordially congratulate our lab members Christian Leinenbach and Wookjin Lee to their great achievement!

Empa mission in space

In March 2004, the Rosetta orbiter was launched into space to analyse and observe the nucleus and environment of the comet 67P/Churyumov-Gerasimenko. Among the equipment on board were highly complex metal ceramic sensors from Empa – integrated into two mass spectrometers, as manufactured by a team led by our colleague of the laboratory of Joining Technologies, Dr. Hans Rudolf Elsener. The devices were specially developed for the mission to measure gas particles in the vicinity of the comet. Coming August, Rosetta will have its encounter with the 67P/Churyumov-Gerasimenko comet.

In 2013, Elsener and his team also finished highly complex modules and sensors for the coming European/Japanese "BepiColombo" mission to Mercury and are currently developing a new ion optical sensor for an even smaller and lighter mass spectrometer for the Russian/Indian "LUNA" Moon mission.

A detailed news item can be found here: english or german version. Further information about the Rosetta Mission is available on the ESA website. We cordially congratulate our colleagues on these great achievements.

The 2nd International Conference on Nanojoining and Microjoining 2014

Key technologies in the fields of e.g. micro-electronics, medical implants, sensing devices and packaging have an urgent need for advanced joining technologies to integrate, package and assemble nano- and micro-scale materials and components at ever-lower temperatures. While microjoining has already become one of the most critical technical prerequisites in the manufacturing of micro-devices and micro-systems, many technological advancements are still needed to allow faster and more reliable fabrication, continuing miniaturization and further cost reduction. The field of nanojoining is also evolving rapidly and is expected to become a key technology for the large-scale production and commercial application of nano-devices and nano-systems in the coming decades.

Our laboratory is honoured to organize and chair the 2nd International Conference on Nanojoining and Microjoining (NMJ2014), which will be held from 7th - 10th December 2014 in Emmetten, Switzerland. The conference provides a platform for scientific exchange in the emerging fields of nano- and micro-joining technologies, i.e.

  • Joining for integration of nano-/micro-scale materials and devices
  • Process issues in nano-/micro-joining
  • Method development for nano-/micro-joint characterization
  • Fundamentals of nano-/micro-joining technologies

We are looking forward to receive your abstract for participation online via the official website at
