In the title complex, [Cu(H(2)NCH(2)CH(2)NH(2))(3)](CF(3)COO)(2), the environment of the Cu atom is distorted octa-hedral, formed by six N atoms from three chelating ethane-1,2-diamine ligands. The Cu-N distances range from 2.050 (2) to 2.300 (2) Å. This complex cation and the two trifluoro-acetate anions are connected by weak N-H⋯O and N-H⋯F hydrogen bonds, forming a three-dimensional framewor...

In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichlor...

In the title compound, [Cu(C(76)H(92)N(4)O(4))], the central Cu(II) ion is situated on an inversion centre. The porphyrinate core exhibits a nearly planar conformation [maximum deviation = 0.027 (3) Å], with Cu-N distances of 1.997 (2) and 2.001 (2) Å. The benzene rings of the 4-octyloxyphenyl groups are rotated at angles of 84.02 (8) and 77.02 (6)° with respect to the mean plane of the porphyr...

One method for defining pathways through which children develop severe conduct problems is based on the presence or absence of callous-unemotional (CU) traits. This study investigated potential differences between nonreferred children (mean age = 12.36 years; SD = 1.73) with and without CU traits (n = 98). Children with conduct problems, irrespective of the presence of CU traits, tended to have...

Chronic spontaneous urticaria has a substantial impact on patients' quality of life. The first disease-specific tool to assess quality of life impairment in this condition, the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL), was developed recently. The aim of this study was to adapt the original Italian version to the Turkish language and to evaluate its reliability, validity, and se...

It is known that the glass forming-ability (GFA) of bulk metallic glasses (BMGs) can be greatly enhanced via minor element additions. However, direct evidence has been lacking to reveal its structural origin despite different theories hitherto proposed. Through the high-resolution transmission-electron-microscopy (HRTEM) analysis, here we show that the content of local crystal-like orders incre...

The facile preparation of high-purity carbon nanofibers (CNFs) remains challenging due to the high complexity and low controllability in reaction. A novel approach using gas-induced formation of Cu crystals to control the growth of CNFs is developed in this study. By adjusting the atmospheric composition, controllable preparation of Cu nanoparticles (NPs) with specific size and shape is achieve...

In the title compound, [Cu(C(2)H(3)N)(2)(C(22)H(28)N(2)O(6))]ClO(4), the Cu atom is coordinated by two N atoms from one bidentate Schiff base ligand and two N atoms from two acetonitrile groups. The Cu atom adopts a tetra-hedral geometry. The Cu-N(ligand) distances are 2.076 (3) and 2.089 (3) Å, and the Cu-N(acetonitrile) distances are 1.964 (4) and 1.975 (4) Å.

DNA intercalators are found to recognize a DNA lesion as a high affinity receptor site. This lesion-specific binding is observed when one strand of a DNA double helix contains an extra, unpaired nucleotide. Our assay for binding controls for the effects of sequence with a series of oligodeoxynucleotide duplexes which are identical except for the location of the lesion, an extra cytidine. Scissi...

We report a new pathway to fabricate armchair graphene nanoribbons with five carbon atoms in the cross section (5-AGNRs) on Cu(111) surfaces. Instead of using haloaromatics as precursors, the 5-AGNRs are synthesized via a surface assisted decarboxylation reaction of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA). The on-surface decarboxylation of PTCDA can produce extended copper-perylen...
