IKBFU physicists have successfully tested the new magnetic micro wire-based concept of 'smart' composites production
IKBFU Physicists have successfully tested the new magnetic micro wire-based concept of "smart" composites production. The new composites are related to the multiferroic-class materials which have mutually controlled magnetic and electric properties. The effects observed in the compositions are considered to be a perspective platform for creating new devices from energy converters to highly sensitive sensors.

These magnet-electrical sensors are of high demand in biomedicine because of being used in health monitoring devices. There already are prototypes of the sensors and further research is going on to improve the sensors' functional characteristics.
The IKBFU Laboratory of Novel Magnetic Materials scientists have an idea to use the amorphous microwire composite as a magnetic component. This approach will allow the scientists to get a compact human-hair thick sensor, capable of registering even very weak magnetic fields.
Senior researcher of the IKBFU Laboratory of Novel Magnet Materials Karim Amirov said:
"This new conception has already proved to be effective. We aim our research at both checking the conception and at getting the composition with maximal magneto-electric effect. This means that a series of experiments was conducted to search for such a microwire preparation protocol (annealing, removal of the glass shell) that would ultimately give us the maximum output.
This is very important because after we understand how it works, what microwire to use and how to prepare it, the next step is to get such a composite in a flexible piezopolymer matrix. This will be another step towards the magnetoelectric sensor being developed for monitoring human parameters".
The article with the results of the research were published in the Materials Scientific Journal. The article authors are the scientists at the IKBFU Laboratory of Novel Magnetic Materials: Ph.D. Candidates in Physics and Mathematics Karim Amirov, Valeria Rodionova and Irina Baraban, Ph.D. in Physics and Mathematics Larisa Panina.

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...
