In the crystal structure of the title compound, C(16)H(11)NO(5)S, the plane of the naphthalene ring system forms a dihedral angle of 63.39 (8)° with the benzene ring. The nitro group makes a dihedral angle of 10.73 (16)° with the benzene ring. Weak intra- and inter-molecular C-H⋯O inter-actions are observed.

The organic anion of the title compound, {[Na(C(15)H(9)O(10)S)(H(2)O)(2)]·H(2)O}(n) {systematic name: poly[[diaqua-[μ-2-(3,4-dihy-droxy-phen-yl)-3,5,7-trihy-droxy-4-oxo-4H-chromene-8-sulfon-ato]-sodium] monohydrate]}, has a nearly planar structure. The Na atom is six-coordinated by O atoms, two from water mol-ecules and four from the anion. The dihedral angle between the ring systems in the ani...

The purpose of this study was to propose a conceptual model for technology transfer (TT) that houses several factors. These factors are believed to influence the processes’ effectiveness and guide the TT performance. In addition, this study aimed to explore TT performance and the relationship between TT government support, infrastructure, TT environment, and TT learning capability. Oil producti...
