Entanglement distribution maximization over one-side Gaussian noisy channel
The optimization of entanglement evolution for two-mode Gaussian pure states
under one-side Gaussian map is studied. Even there isn't complete information
about the one-side Gaussian noisy channel, one can still maximize the
entanglement distribution by testing the channel with only two specific states
Triggers of Permo-Triassic boundary mass extinction in South China: the Siberian Traps or Paleo-Tethys ignimbrite flare-up?
2-Nitro-N-(4-pyridinio)benzenesulfonamidate monohydrate
The title compound, C11H9N3O4S·H2O, contains both an acid and a base centre and displays a zwitterionic structure. There are two independent molecules and two water molecules in the asymmetric unit. The dihedral angles between the benzene ring and the pyridinium ring are 109.7 (1) and 110.7 (1)°. The dihedral angles between the nitro group and the benzene ring are 116.1 (2) and 116.7 (1)°. The crystal structure is stabilized by N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds
4-(4-Nitrobenzenesulfonamido)pyridinium nitrate
A short C—N distance [1.394 (2) Å] in the title compound, C11H10N3O4S+·NO3
−, is indicative of some conjugation of the sulfonamide π electrons with those of the pyridinium ring. The crystal structure is stabilized by N—H⋯O hydrogen bonds
