Fabrication and Application of a New-Type Photothermal Conversion Nano Composite Coating.

Photothermal conversion nanomaterials attract much attention for their high light/heat transform efficiency and controllable light absorption. In this work, the CuS semiconductor nanomaterials were prepared through the deposition method in the presence of citrate sodium and were characterized by TEM, XRD and UV-vis spectra. A new type of nano composite coating was obtained from acrylic resin by adding the CuS nanoparticles and other nanomaterials which could absorb the light of various infrared bands. The test showed that when exposed to infrared light, the plastic greenhouse model equipped with photothermal conversion coating gave out a more significant temperature rising than that of the common plastic greenhouse. The properties of photothermal conversion and heat insulation of photothermal conversion coating reach the best when the addition quantities of CuS and ZrC nanoparticles are 2%.

Bis(4-acetyl-anilinium) hexa-chlorido-stannate(IV).

In the title compound, (C(8)H(10)NO)(2)[SnCl(6)], the Sn(IV) atom exists in an octa-hedral coordination environment. In the crystal, inter-molecular N-H⋯O and N-H⋯Cl hydrogen bonds link the cations and anions into a three-dimensional framework.

Bis[3-(meth-oxy-carbon-yl)anilinium] hexa-chloridostannate(IV).

In the title compound, (NH(3)C(6)H(4)CO(2)CH(3))(2)[SnCl(6)], the anions are situated on inversion centers so the asymmetric unit contains one cation and one half-anion. In the crystal, inter-molecular N-H⋯Cl and N-H⋯O hydrogen bonds link the cations and anions into layers parallel to the ac plane. The crystal packing exhibits voids of 37 Å(3).

Aqua-(3-carboxybenzoato-κO)(nitrato-κO)(dipyrido[3,2-a:2',3'-c]phenazine-κN,N)copper(II).

The title complex, [Cu(C(8)H(5)O(4))(NO(3))(C(18)H(10)N(4))(H(2)O)], was synthesized by reacting Cu(NO(3))(2), isophthalic acid and dipyridophenazine under hydro-thermal conditions. The Cu(II) ion is in a slightly distorted square-pyramidal coordination environment. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect complex mol-ecules into chains along [001].

catena-Poly[[bis-[(2-carboxy-benzoato-κO)silver(I)](Ag-Ag)]bis-(µ-isonicotinic acid-κN:O)].

The title compound, [Ag(C(8)H(5)O(4))(C(6)H(5)NO(2))](n), contains one Ag(I) atom, one phthalate ligand and one isonicotinic acid mol-ecule in the asymmetric unit. Each Ag atom is three-coordinated in a T-shaped geometry by two O atoms and one N atom from one phthalate ligand and two isonicotinic acid ligands. The isonicotinic acid ligand bridges two Ag atoms, forming a one-dimensional chain. Adjacent chains are linked by Ag-Ag inter-actions, leading to a double-chain. These double-chains are further linked via hydrogen bonds into a two-dimensional layer.

2,3-Diamino-phenazine tetra-hydrate.

The title compound, C(12)H(10)N(4)·4H(2)O, was obtained from a room-temperature solution of o-phenyl-enediamine and copper acetate. In the crystal structure, there are significant π-π stacking inter-actions, with a centroid-centroid separation of 3.575 (2) Å. In addition, inter-molecular O-H⋯O, N-H⋯O, N-H⋯N and O-H⋯N hydrogen bonds link 2,3-diamino-phenazine mol-ecules and water mol-ecules, forming a three-dimensional framework.

catena-Poly[[bis-(µ-3-carboxy-benzoato)bis-(1,10-phenanthroline)tricopper(II)]-di-µ(3)-isophthalato].

The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π-π stacking inter-actions (face-to-face distance ca 3.45 Å) and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

A novel one-step chemical method for preparation of copper nanofluids.

This paper presents a novel one-step method for preparing of copper nanofluids by reducing CuSO(4).5H(2)O with NaH(2)PO(2).H(2)O in ethylene glycol under microwave irradiation. Nonagglomerated and stably suspended Cu nanofluids are obtained. The influences of CuSO(4) concentration, addition of NaH(2)PO(2), and microwave irradiation on the reaction rate and the properties of Cu nanofluids were investigated by transmission electron microscopy, infrared analysis, and sedimentation measurements. It is found to be a fast, efficient one-step chemical method to prepare Cu nanofluids.
