Every manufacturing process, from casting and forging, to machining and finishing, induces residual stresses in components. For critical components, such as aircraft wings and turbine blades, these stresses affect the durability and lifetime of the structures and assemblies. Current methods are either destructive (e.g. hole drilling), limited to the surface (laboratory X-ray), or rely on large facilities (synchrotron and neutron sources). The new method uses a laboratory source of high energy polychromatic X-ray in transmission to evaluate stresses in the bulk of the sample. The method is portable and can be adapted to any number of demanding applications.
There are a number of important advantages that the new instrument has over existing techniques, the main one being that it is a truly non-destructive method for bulk stress measurement. It has transmission measurement capability using a high energy beam. It is capable of producing a penetration depth of 25mm in Aluminium, >5mm in steel and nickel and high X-ray photon flux. The equipment is portable, robust and particularly suitable for use on large and assembled components. The simplicity of the design means that it would be extremely cost effective to produce and reduce significantly the time and degree of technical know-how required to complete the process.
This portable prototype meets the challenges associated with testing for residual stress across a wide range of engineering components and structures. Isis would like to talk to companies interested in developing the commercial opportunity that this represents. If you require any further information, please contact Isis Innovation Ltd.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
