Indirect determination of cefradine with n-propyl alcohol-ammonium sulfate-water system by extraction-flotation of cuprous thiocyanate

A new method was developed for the determination of cefradine by extraction-flotation of CuSCN. The experiment indicated that in the presence of 0.20 mol/L NaOH the degradation of cefradine took place in water bath at 100 C. The thiol group (-SH) of the degradation product could reduce Cu(II) to Cu(I) for the formation of the emulsion CuSCN in the presence of NH4SCN at pH 4.0. By determining the residual amount of Cu(II) in the solution and calculating the flotation yield of Cu(II), the indirect determination of cefradine can be obtained. This method has been applied to determine cefradine in capsules, human serum and urine samples, respectively.

Delayed Annealing Treatment for High-Quality CuSCN: Exploring Its Impact on Bifacial Semitransparent n-i-p Planar Perovskite Solar Cells

Inorganic p-type copper(I) thiocyanate (CuSCN) hole-transporting material (HTM) belongs to a promising class of compounds integral for the future commercialization of perovskite solar cells (PSCs). However, deposition of high-quality CuSCN films is a challenge for fabricating n-i-p planar PSCs. Here we demonstrate pinhole-free and ultrasmooth CuSCN films with high crystallinities and uniform coverage via delayed annealing treatment at 100 C, which can effectively optimize the interfacial contact between the perovskite absorber and the electrode for efficient charge transport. A satisfactory efficiency of 13.31% is achieved from CuSCN-based n-i-p planar PSC. In addition, due to the superior transparency of p-type CuSCN HTMs, it is also possible to prepare bifacial semitransparent n-i-p planar PSCs, which eventually permits a maximum efficiency of 12.47% and 8.74% for the front and rear illumination, respectively. The low-temperature process developed in this work is also beneficial for those applications such as flexible and tandem solar cells on heat-sensitive substrates.

In situ synthesis and characterization of Cu2O nanowire networks from CuSCN films

Cuprous oxide (Cu2O) nanowire films were in situ grown from pre-deposited cuprous thiocyanate (CuSCN) films which acted as sacrificial precursors. The synthesis was processed in air from NaOH solution, providing an appealing alternative to nanowire-based porous films. Plausible solid-liquid interface reactions were described. Structural analysis showed that Cu 2O nanowires were p-type polycrystalline semiconductor, with high aspect ratio of 10-30 nm in diameter and more than 1 um in length, and they were found to be interlaced with each other in the formation of interpenetrating networks within the Cu2O film which possessed large-area uniformity. It is noteworthy that the nanowire-based films actually are porous films embedded with various interwire spaces and cavities. Photoelectrochemical measurements revealed that a Cu2O film with thickness of 500-1000 nm generated zero-bias photocurrent of approximately 1.5 muA cm-2. The present synthesis is facile and low-cost, and is expected to be suitable for mass production of large-area semiconductor films under ambient condition.

Preparation of buta-1,3-diynyl complexes of platinum(II) and their use in the construction of neutral molecular squares: Synthesis, structural and theoretical characterisation of cyclo-{Pt(mu-C?CC?C)(dppe)}4 and related chemistry

Copper(I)-catalysed reactions of cis-PtCl2(L)2 (L= PEt3, L2 = dppe, dppp) with buta-1,3-diyne have given the corresponding diynyl complexes, cis-Pt(C?CC?CH)2(L)2 (L= PEt3 1, L2 = dppe 2, dppp 3) whose solid-state structures have been determined from single crystal X-ray diffraction studies. Theoretical calculations were carried out to probe the electronic structure of these diynyl complexes. Complex 2 reacts with Co2(CO)8 to give a bis-adduct 5 and with Ru3(mu-dppm)(CO)10 to give a mono-adduct 6; in both, the least hindered C?C triple bond(s) is(are) coordinated. Lithiation (LiBut) of 2 gives a dilithio derivative, which has been converted to dimethyl 7 or mono-SiMe3 8 or -Au(PPh3) 9 complexes. Cu(I) and Ag(I) (MI) adducts (quot;tweezerquot; complexes) have been obtained from reactions of 2 with MISCN or [MI(NCMe)4]+. An ES mass spectrometric study of the interactions of 2 with Group 1 cations and with Tl+ is also described; comparative experiments with {W(CO)3Cp}2(mu-C8), in which the four C?C triple bonds do not have a “tweezer” conformation, have also been carried out. The degree of association is determined by the competitive solvation of the Group 1 cation. Coupling of the buta-1,3-diynyl complexes with Pt(OTf)2(L?)2 gives homo- or mixed-ligand molecular squares cyclo-{(L)2Pt(mu-C?CC?C)2Pt(L?) 2}2 (L, L? = PEt3, L2, L?2 = dppe, dppp; not all combinations), of which the molecular structure of cyclo-{Pt(mu-C?CC?C)(dppe)}4 17 is described (as solvates containing dmso). The molecular squares form adducts with substituted ammonium triflates [NH2R2][OTf] (R = Et, Pri, Cy; NH2R2 = dbuH) and with Group 11 cations [MI(NCMe)]+.

Biophotovoltaics: Natural pigments in dye-sensitized solar cells

Dye-sensitized solar cells (DSSCs) which are also called Graetzel cells are a novel type of solar cells. Their advantages are mainly low cost production, low energy payback time, flexibility, performance also at diffuse light and multicolor options. DSSCs become more and more interesting since a huge variety of dyes including also natural dyes can be used as light harvesting elements which provide the charge carriers. A wide band gap semiconductor like TiO2 is used for charge separation and transport. Such a DSSC contains similarities to the photosynthetic apparatus. Therefore, we summarize current available knowledge on natural dyes that have been used in DSSCs which should provide reasonable light harvesting efficiency, sustainability, low cost and easy waste management. Promising natural compounds are carotenoids, polyphenols and chlorophylls.

Synthesis and structural characterization of five new copper (I) complexes with 1,10-phenanthroline and 1,4-bis(diphenylphosphino)butane(dppb)

The mixture of copper(I) salts CuX (X = Cl, Br, SCN, CN, SO3CF3) and 1,10-phenanthroline (phen) reacts with 1,4-bis(diphenylphosphino)butane (dppb) to give dinuclear complexes [Cu2(dppb)(phen)2Cl2]¡¤4DMF (1), [Cu2(dppb)(phen)2Br2]¡¤DMF (2), [Cu2(dppb)(phen)2(SCN)2] (3) and two 1D chain complexes {[Cu2(dppb)(phen)2(CN)2(H2O)]}n¡¤nH2O (4) and {[Cu2(dppb)(phen)2](SO3CF3)2}n (5), respectively. The structures of these compounds were investigated by elemental analysis, single-crystal X-ray diffraction, electronic absorption spectroscopy, fluorescence spectroscopy, 1H NMR and 31P NMR spectroscopy. Each Cu atom adopts a distorted tetrahedral configuration, and all the complexes are considerably air-stable in solid state and in solution. Detailed NMR studies have been performed to disclose the behavior of the prepared copper(I) complexes in solution. All the five complexes are bright green and cyan luminophores in a solid state at room temperature. This makes them potential candidates as cheap emitting materials for electroluminescent devices.

Thiocyanate hydrometallurgy for the recovery of gold. Part I: Chemical and thermodynamic considerations

Thiocyanate has been identified and studied as a promising alternative lixiviant for gold in acidic solutions. Eh-pH and ion species distribution diagrams for SCN-H2O, Au-SCN-H2O, Ag-SCN-H2O, Cu-SCN-H2O, and Fe-SCN-H2O systems were constructed to predict the behavior of each metal ion in the thiocyanate system and also to explain the experimental results. Thermodynamic analyses suggest that gold can be leached by thiocyanate under appropriate leaching potentials, forming aurous or auric complexes with thiocyanate, depending on the thiocyanate concentration and leaching potential. According to species distribution diagrams, silver (I) and copper (I) form insoluble salts at moderate thiocyanate concentrations and are soluble at low and high thiocyanate concentrations. Ferric ion forms a series of complexes with thiocyanate. The study of the ferric ion effect indicates that gold can be leached in acid thiocyanate solution with ferric sulfate as the oxidant. Also the presence of excess ferric ion reduces the apparent thiocyanate activity for copper (I) and silver (I) dissolution. The findings of this thermodynamic assessment are useful in the analysis of some of the phenomena encountered in the leaching and recovery of gold from thiocyanate solutions as discussed in subsequent papers.
