摘要：
The title compound, C19H13BrClN, was synthesized by N-alkyl-ation of 4-chloro-1-(chloromethyl)benzene with 3-bromo-9H-carbazole. The carbazole ring system is essentially planar, with a mean deviation of 0.028 Å, and it makes a dihedral angle of 91.2 (3) Å with the plane of the benzene ring.

摘要：
The effects of multi-walled carbon nanotubes (MWNTs) on the phase change enthalpy (Delta H) and the thermal conductivity (kappa) of a solid-liquid phase change materials (PCM), palmitic acid (PA), have been investigated. The results showed that both the Delta H and the kappa of the composite were lower than that of PA when the loading of MWNTs was small. As the concentration of MWNTs in the composites increased, the Delta H of the composites was slightly improved and then decreased linearly. However, the kappa of the composites was monotonously increased from the minimum value. When the loading of MWNTs increased to 5% and no surfactant was added, the kappa of the composite was enhanced to be 26% higher than that of PA. The kappa of the composite could be enhanced by CTAB instead of SDBS when the loading of MWNTs was small, as SDBS showed no obvious effect on the kappa of the composites. Furthermore, the effects of surface modification of MWNTs on the Delta H and the kappa of the composites have also been investigated.
摘要：
A micro-envioment for nerve cells and tissue growth were designed and constructed via surface modification of poly(L-lactide-co-glycolide)(PLGA) with chitosan and hydroxyapatite(HA). The poly(L-lactide-co-glycolide)/chitosan/hydroxyapatite (PLGA/chitosan/HA) conduits were manufactured by a combined solvent casting and particulate leaching technique. The conduits were highly porous with an interconnected pore structure and 76.5% porosity. Micropores with 50–100 micrometer diameter were formed in the conduits. In vivo application of PLGA/chitosan/HA conduits for reconstruction of 10 mm sciatic nerve defect was assessed by the walking track analysis, the quantifying of the wet weight of tibialis anterior muscle and the histological assessment. The conduits in host rats in vivo can not only be an effective in promoting regenerating of nerves but can also lead to favorable nerve functional recovery.

摘要：
In the title compound, C11H11N2O 2S+·NO3 -, the dihedral angle between the benzene and pyridinium rings is 87.59 (8)°. An intra-molecular C - H⋯O inter-action occurs in the cation. In the crystal structure, ion pairs occur, being linked by two strong N - H⋯O inter-actions, forming R 2 2(8) loops. The packing is further stabilized by weak C - H⋯O inter-actions.
