The recent advances in the fields such as modeling bio-mechanics of living tissues, haptic technologies, computational capacity, and virtual environments have created conditions necessary in order to develop effective surgical training and learning methods. Simulation environments for surgical training have no limitations on the number of times a procedure(More)
We study the origin of the magnetoelectric coupling in manganite films on ferroelectric substrates. We find large magnetoelectric coupling in La0.7Ca0.3MnO3/BaTiO3 ultra-thin films in experiments based on the converse magnetoelectric effect. The magnetization changes by around 30-40% upon applying electric fields on the order of 1 kV/cm to the BaTiO3(More)
The blocking of ion transport at interfaces strongly limits the performance of electrochemical nanodevices for energy applications. The barrier is believed to arise from space-charge regions generated by mobile ions by analogy to semiconductor junctions. Here we show that something different is at play by studying ion transport in a bicrystal of yttria (9%(More)
