Bis(2-amino-3-nitropyridinium) dichromate(VI)

Studies on the Synthesis, Growth, Characterization of 2-amino- 5-nitropyridinium-toluenesulfonate Single Crystals

Multiband superconductivity in BiS2-based layered compounds.

A mean-field treatment is presented of a square lattice two-orbital-model for [Formula: see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula: see text]) and electron doping x. With the help of ...

4-Amino-3-ammonio­benzene­sulfonate

The title compound, C(6)H(8)N(2)O(3)S, crystallized as a sulfonate-aminium zwitterion. In the crystal, inter-molecular N-H⋯O hydrogen bonds generate an extensive three-dimensional network, which consolidates the packing.

Discovery of BiS2-Based Superconductor and Material Design Concept

In 2012, we discovered new layered superconductors whose superconducting states emerge in the BiS2 layers. Since their crystal structure, composed of alternate stacks of BiS2 conduction layers and electrically insulating (blocking) layers, is similar to those of cuprate and Fe-based superconductors, many researchers have explored new BiS2-based superconductors and have studied the physical and ...

2-Amino-3-nitro­benzoic acid

The title compound, C(7)H(6)N(2)O(4), is approximately planar (r.m.s. deviation = 0.026 Å for the 13 non-H atoms). The mol-ecular structure is stabilized by intra-molecular N-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network.
