Transition metal oxides (TMOs) are emerging strong players in many domains, ranging from superconductivity, to microelectronics to spintronics to light harvesting for photovoltaics. Beyond their non-toxicity, low corrosiveness and low price, they exhibit a ...
One of the biggest goals for the international thermonuclear experimental reactor (ITER) is the steady state operation. For this reason all its coils will be superconducting and Nb3Sn material is used for both the toroidal field (TF) and the central soleno ...
We report on the electrodeposition of CuX (X = Cl, Br) thin films on fluorine-doped tin oxide (FTO) electrodes. The electrodeposited CuX thin films, for the first time, were used as intermediates to prepare CuO thin films. Calcination of the as-prepared Cu ...
Two preliminary design concepts for the low T-C. superconductor Toroidal Field coil system of the planned European fusion reactor DEMO were proposed in 2012 by EPFL-CRPP PSI Villigen and ENEA Frascati. The coil consists of eight double layers (DLs) wound u ...
The design of a flat cable suitable for future fusion reactors has been carried out. The cable consists of twisted round strands, which are composed of tapes stacked between copper profiles. According to calculations, the strand twist pitch and the cable t ...
Physical properties of surfaces are extremely important for initiation and nucleation of crystal growth, including nanowires. In recent years, fluctuations in surface characteristics have often been related to unreproducible growth of GaAs nanowires on Si ...
The most popular fit for describing the volt-ampere characteristic of a superconducting material is a power law with exponent n. Usually for a Nb3Sn wire the n-index is parametrized as a function of the sole critical current (I-c). An experiment to determi ...
The electron microscopy community makes a wide use of Energy Dispersive X-ray Spectrometry (EDS) for elemental mapping in STEM. This technique was however long reckoned slow, dozens of minutes if not an hour, to collect enough information for one map. Rece ...
The most fundamental limitations of a muon-spin relaxation experiment can be the lack of knowledge of the implantation site of the muon and the uncertainty about the muon's perturbation of its host. Here we review some of the work done on the 'muon site pr ...
In the assumption that DEMO will be an inductively driven tokamak, the number of load cycles will be in the range of several hundred thousands. The requirements for a new generation of Nb3Sn based high current conductors for DEMO are drafted starting from ...
