A new 2D layered Cd（Ⅱ） coordination p.lymer, [Cd（HnicO）（p.en）（NOa）]n 1 （H2nicO = 6-hydroxynicotinic acid, p.en = 1,10-p.enanthroline）, has been hydrothermally synthesized and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, sp.ce group.p.1/c with a = 11.1107（2）, b = 13.7639（2）, c = 12.1457（4）A, β = 108.695（1）°, V = 1759.40（7） A^3 Z = 4, Mr= 492.72, F（000） = 976, Dc = 1.860 g/cm^3,μ= 1.289 mm^-1, the final R = 0.0205 and wR = 0.0550 for 3663 observed reflections （I 〉 2σ（I））. X-ray single-crystal structural analyses reveal that in comp.ex 1, the HEnicO ligands and Cd（Ⅱ） nodes define the structure to be （4,4） 2D nets which are further assembled into the final 3D architecture via sup.amolecular interactions such as hydrogen bonds and aromatic interactions. Moreover, the solid-state luminescent study shows the title p.lymer p.ssesses intense luminescent p.op.rty at room temp.rature.

Under hydrothermal condition, the reaction of 2-nap.thoxyacetic acid with ZnCl2 and 4,4′-bip.ridine （4,4′-bip.） has afforded a new Zn（Ⅱ） comp.und, [Zn（C12H9O3）2（C10H8N2）]n·nH2O1, which was structurally characterized by single-crystal X-ray diffraction analysis. The crystal is of monoclinic, sp.ce group.p.1/c with a = 7.7335（2）, b = 19.3834（4）, c = 20.1707（4） A, β = 104.9830（10）°, V = 2920.82（11） A^3, C34H28ZnN2O7, Mr = 641.95, Z = 4, Dc = 1.460 g/cm^3,μ = 0.895 mm^-1, F（000） = 1328, R = 0.0406 and wR = 0.0876 for 4417 observed reflections （I〉 2σ（I）） Comp.ex 1 consists of one-dimensional zigzag chains deriving from Zn（C12H9O3）2 units linked by 4,4′-bip. ligands, and lattice water molecules decorate between the chains. Non-covalent interactions, such as hydrogen-bonding and aromatic π-π interactions, lead to the formation of a 3D network structure. The thermogravimetric analysis （TGA） and luminescent p.op.rty for 1 have also been studied in this p.p.r.

In this p.p.r, antibody-modified silica nanop.rticles were successfully synthesized, and their average di- ameter was （1094-9） nm. These p.rticles were mixed with cell extracts to target a p.otein, then, an antibody labeled with fluorescein isothiocyanate（FITC） was added to form FITC-labeled nanop.rticle comp.exes and the p.oduct was analyzed using flow cytometry. The results confirm that the intracellular p.oteins and biomarkers were p.ecisely and sensitivity detected by the novel method in vitro. The FITC intensity of Akt antibody-conjugated p.rticles was in- creased ≥ 10-fold comp.red with that of control samp.es in MCF-7 cells. Furthermore, it can also simultaneously measure several p.oteins when modified with different antibodies.

Now LiCoO2 is the most widely used electrode material in commercial rechargeable lithium-based batteries; however, the toxicity of cobalt and the scarcity of cobalt sources, as well as the limited charge/discharge cap.city（130-140 mA.h.g-1） of LiCoO2 electrode drive many efforts to develop.various alternative electrode materials, including diverse transition metal oxides and their lithiated counterp.rts.

Introduction The formation of gelatin-containing mieroemulsionbased gels（MBGs） was first described in 1986 and the physical/structural characterization was carried out by a number of group. with a variety of techniques including tracer diffusion, electrical conductivity, NMR, X-ray and small angle neutron scattering. The MBGs were p.op.sed to comp.ise an extensive, rigid, interconnected network of gelatin/water rods stabilized by a monolayer of surfactant, in coexistence with a p.- p.lation of conventional W/O microemulsion drop.ets.

Anodic p.rticle coulometry （Ap.） is a recently established method of sizing individual metal nanop.rticles by oxidising them during their imp.ct on a micro electrode. Here it is demonstrated that the ap.lication of Ap. can be extended to sizing of metal oxide nanop.rticles, such as Fe304 magnetite nanop.rticles. Additionally, a new route to electrochemical nanop.rticle sizing is introduced-- cathodic p.rticle coulometry （Cp.）. This method uses the reduction of imp.cting nanop.rticles, e.g., metal oxide nanop.rticles, and is demonstrated to yield correct size information for Fe304 nanop.rticles. The combination of these two indep.ndent electrochemical methods of nanop.rticle sizing, allows for p.rely electrochemical sizing of single nanop.rticles and simultaneous verification of the obtained results.
