A material used to protect submarines from sonar detection is the latest technological breakthrough in ensuring the safe and effective dose of ultrasound in medicine. Practitioners and thousands of patients in physiotherapy departments worldwide will benefit from the latest technology, which will ensure a step forward in the reliability of delivered ultrasound treatment.
The material forms a key component in a novel desk-top ultrasound power meter developed by the UK’s national standards laboratory, The National Physical Laboratory (NPL) of Teddington, UK, in partnership with one of the leading manufacturers of ultrasound measurement equipment, Precision Acoustics Ltd (PA), Dorchester, UK.
An estimated 10,000 physiotherapy ultrasound units are currently in use in the UK alone. Key to ensuring that patients are receiving the most effective treatment for their soft tissue injuries is the assurance that the equipment delivers the correct level of ultrasound power. Physiotherapists will benefit from the latest measurement development to carry out their everyday treatments.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
