The title compound, C(13)H(13)BN(2)O, is one in a series of 1,3,2-benzodiaza-boroles featuring a 2-meth-oxy-phenyl substitution at the 2-position in the nitro-gen-boron heterocyle. The dihedral angle between the mean planes of the benzodiaza-borole and 2-meth-oxy-phenyl ring systems is 21.5 (1)°. There is an inter-molecular hydrogen bond between one of the NH groups and the meth-oxy O atom. Thi...

In the title compound, C(16)H(16)BrNO(4), the dihedral between the planes of the aromatic rings is 7.74 (18)°. The amide group is tilted with respect to the bromo- and meth-oxy-substituted aromatic rings by 36.3 (8) and 35.2 (8)°, respectively. The meta-meth-oxy groups are essentially in-plane with the aromatic ring [dihedral angles CH(3)-O-C-C = -4.6 (4) and -2.5 (4)°]. The para-meth-oxy group...

A 0.5 MW class oxy-fuel boiler was developed to capture CO2 from exhaust gas. We adopted natural gas as the fuel for industrial boilers and identified characteristics different those of pulverized coal, which has been studied power plants. also examined combustion without flue recirculation (FGR), is not commonly in plant boilers. Oxy-fuel involves a stretched flame that uniformly heats chamber...

IN THE TITLE SYDNONE COMPOUND [SYSTEMATIC NAME: 3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(9)H(8)N(2)O(3), the essentially planar oxadiazole ring [maximum deviation = 0.005 (1) Å] is inclined at a dihedral angle of 30.32 (8)° with respect to the benzene ring. In the crystal, adjacent mol-ecules are inter-connected by inter-molecular C-H⋯O hydrogen bonds into sheets lying parallel ...

The title mol-ecular salt, C8H12N(+)·C4H3O4 (-), crystallized with two independent cations and anions in the asymmetric unit. The ethanaminium side chains of the cations exhibit anti conformations [C-C-C-N torsion angles = 176.5 (3) and -179.4 (3)°]. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds connect adjacent anions and cations, and , O-H⋯O hydrogen bonds connect adjacent anions, generating...

The title compound, C(12)H(10)N(2)O(2), was obtained unintentionally during the synthesis of 2-amino-5-(4-meth-oxy-phen-yl)furan-3-carbonitrile. In the crystal, weak inter-mol-ecular C-H⋯N and C-H⋯π inter-actions link the mol-ecules into columns propagating in [010].

Klebsiella oxytoca strains are generally moderately resistant to amoxicillin and ticarcillin due to the activities of the chromosomally encoded OXY-1 and OXY-2 class A beta-lactamase families. These enzymes have the ability to hydrolyze not only penicillins but also cephalosporins, including cefuroxime, ceftriaxone, and aztreonam, and are inhibited by clavulanic acid. A Klebsiella oxytoca strai...

In the present study, we monitored hemodynamic responses in rat brains during transcranial direct current stimulation (tDCS) using functional near-infrared spectroscopy (fNIRS). Seven rats received transcranial anodal stimulation with 200 μA direct current (DC) on their right barrel cortex for 10 min. The concentration changes of oxygenated hemoglobin (oxy-Hb) were continuously monitored during...
