In the title coordination compound, [Cu(NCS)(C(9)H(7)N)(C(18)H(15)P)](n), the Cu(I) atom is tetra-hedrally coordinated by one N atom from an isoquinoline ligand, one P atom from a triphenyl-phospane ligand, and one N and one S atom from two thio-cyanate anions. The thio-cyanide anions bridge the Cu(I) atoms into a chain along [100]. π-π inter-actions between the pyridine and benzene rings of th...
În prezenta lucrare a fost realizat un studiu asupra evoluţiei presiunii în timpul exploziei sub formă de deflagraţie produse în amestecuri propan-aer aflate într-o celulă cilindrică (Φ = 10 cm; h = 15 cm) cu aprindere centrală, la diferite concentraţii iniţiale de propan (între 2.60 şi 5.70%, in vol.), la diferite presiuni iniţiale (între 0.3 şi 1.3 bar) şi la temperatura iniţială ambiantă. Su...
The CopC protein from Pseudomonas syringae pathovar tomato is expressed as one of four proteins encoded by the operon CopABCD that is responsible for copper resistance. It is a small soluble molecule (10.5 kDa) with a beta-barrel structure and features two distinct copper binding sites, which are highly specific for Cu(I) (K(D) > or = 10(-)(13)) and Cu(II) (K(D) approximately 10(-)(15)). These ...
The complete mol-ecule of the title complex, [Cu(3)(C(15)H(13)N(2)O(3))(2)(C(5)H(5)N)(2)], is generated by crystallographic twofold symmetry, with the central Cu atom lying on the rotation axis: it is coordinated by two N,O-bidentate ligands in a trans-CuN(2)O(2) distorted square-planar arrangement. The other Cu atom is coordinated by an N,O,O'-tridentate ligand and a pyridine mol-ecule in a di...
The Cu(II) atom in the title compound, [Cu(NCS)(2)(C(16)H(15)N(3)O)], is bonded to the N atoms of two thio-cyanate ions, and is N,N'-chelated by the Schiff base ligand. The four N atoms surround the metal atom to form a distorted square; the square environment is distorted towards a square pyramid by a long Cu⋯O inter-action. In the crystal, two C atoms of the pyrrolidin-2-one ring are disorder...
Local structure of the Cu02 plane in Bi2Sr2CaCu208+8 (Bi2212) superconductor has been solved by joint Cu K-edge extended X-ray absorption fine structure (EXAFS) and anomalous X-ray diffraction. The Cu-0 pair distribution function (PDF) has been measured by EXAFS and diffraction. The displacement of the Cu ions along the c-axis shows largest amplitude and anharmonic character. The results show f...
The asymmetric unit of the title compound, [Cu(2)Cl(4)(C(15)H(14)N(4))(2)], contains two halves of two centrosymmetric dinuclear mol-ecules, A and B. The conformations of the two crystallographically independent mol-ecules are slightly different: in A, the Cu⋯Cu separation is 4.174 (9) Å and the dihedral angle between the triazole and phenyl rings is 74.23 (11)°; these values are 4.137 (9) Å an...
There is increasing interest in the stabilization of heavy metals in road-derived sediments (RDS), to enable environmentally responsible reuse applications and circumvent the need for costly landfill disposal. To reduce the mobility of heavy metals (i.e. Cu, Pb and Zn) the effectiveness of amendments using phosphate, compost and fly ash addition were investigated using batch leaching experiment...
BACKGROUND Approximately one third of children who meet criteria for conduct problems (CP) are also characterized by elevated callous-unemotional (CU) traits. This subgroup is at elevated risk for more pervasive and extreme levels of later antisocial behavior and has been characterized by a fearlessness temperament and blunted stress psychophysiology at older ages. The objective of this study w...
The joining of lead-free Sn-3.0Ag-0.5Cu (SAC305) solder alloy to metal substrate with the addition of a porous Cu interlayer was investigated. Two types of porous Cu interlayers, namely 15 ppi—pore per inch (P15) and 25 ppi (P25) were sandwiched in between SAC305/Cu substrate. The soldering process was carried out at soldering time of 60, 180, and 300 s at three temperature levels of 267, 287, ...
