FZU researchers recently introduced a new transformation induced plasticity (TRIP) like deformation mechanism activated in NiTi shape memory alloys at elevated temperatures and stresses. The mechanism involving coupled martensitic transformation, deformation twinning and dislocation slip explains gradual loss of functional behavior of NiTi alloys with increasing temperature and stress, refinement of microstructure and excellent deformability at very high stresses.

Discoveries made by the international team of the ASPIN project lead by Tomáš Jungwirth from the Department of Spintronics and Nanoelectronics of the Institute of Physics of the Czech Academy of Sciences have attracted worldwide attention. In order to create a new type of memory its members have used antiferromagnets, materials that had never before been considered for these purposes - not even theoretically.

A collaboration of Japanese and Czech researchers has realized a molecular circuit involving an antiaromatic molecule for the first time. Antiaromatic molecules have 4n electrons in the π system. They had been predicted decades ago to have remarkable electron transport properties but their instability and difficult synthesis had prevented their study until now. In their paper published in Nature Communications, the authors explain the origin of this high conductance compared to the aromatic counterpart.
