Fault Current Limitation in Electrical Power Networks Containing HTS Cable and HTS Fuse.

Numerical calculations of parameters of an electrical power network where an HTS fuse is used as a fault current limiting device have been done. The calculations were performed for networks containing different types of HTS cables as well. The design of HTS fuse was developed based on the numerical calculation for the network-rated parameters considering the special types 2G HTS tape characteristics.

A Family of Lanthanide Hydroxo Carboxylates with 1D Polymeric Topology and Ln Butterfly Core Exhibits Switchable Supramolecular Arrangement.

The unique family of coordination polymers [Ln(OH)(piv)(HO)] of 11 lanthanides (Ln = La-Er) has been prepared by a simple solution method based on controlled hydrolysis. The ribbon-like polymeric structure consisting of connected tetranuclear clusters and supported by pivalate ligands and a framework of H-bonds has been revealed by single-crystal X-ray diffraction. While the compounds demonstrate similar PXRD patterns and unit cell parameters, the joint single-crystal XRD and pair distribution function data suggest the significant local structure change along the lanthanide series.

Microstructure and superconducting properties of high-rate PLD-derived GdBaCuO coated conductors with BaSnO and BaZrO pinning centers.

The microstructure of GdBaCuO based on superconducting tapes with BaSnO and BaZrO artificial pinning centers formed by high-rate pulse laser deposition in SuperOx Japan was studied by scanning/transmission electron microscopy. The artificial pinning centers have adopted columnar morphology with average diameter of about 8 nm (BaSnO-doped sample) and 6.5 nm (BaZrO-doped sample) and density of 500 μm for the both samples.
