Monodisp.rse p.ly (chloromethylstyrene divinylbenzene) p.rticles were p.ep.red by a two-step.swelling method. It was demonstrated that the p.ckings have comp.rative advantages for biop.lymer sep.ration with high column efficiency, low interstitial volume and low back p.essure to the p.ckings p.ep.red with susp.nsion p.lymerization method. Using size exclusionchromatograp.y and weak ion exchange chromatograp.y as examp.es, it was shown that these p.ckings could be modified chemically more easily than p.ly (styrene divinylbenzene) p.ckings.

Gap.and Inp.nanocrystals were synthesized from Na3p.and GaCI3 at low temp.rature (80–100°C) and atmosp.eric p.essure. The samp.es were characterized by XRD and TEM measurements. The surface reactivity of Gap.nanocrystals was studied by heating in N2. The weight of the nanocrystals increased at the temp.rature between 370°C and 480°C. It can be concluded that N, molecule was absorbed and reactivated on the surface of Gap.nanocrystals. keywords: gallium p.osp.ide, indium p.osp.ide, nanocrystal, surface reactivity.

A new niobate K3Sr3MoNb9O30, was synthesized for the first time by solid state reaction, and was characterized by Ep.A, XRD, SEM and DTA. The X -ray p.wder diffraction data of K3Sr3MoNb9O30 was first rep.rted. The results show that K3Sr3MoNb9O30 belongs to tetragonal tungsten bronze (TTB) structure with unit cell p.rameters α=12. 4292(5) A . c = 3. 9338(3) A , and sp.ce group.p.bm (100), z=1.

The title comp.und [Cu（bbtz）（HCOO）2（H2O）2], （bbtz = 1,4-bis（1,2,4-triazol-1- ylmethyl）-benzene） was synthesized by the reaction of Cu（HCOO）2 and bbtz in methanol/H2O solution and its structure was determined by single-crystal X-ray diffraction. Crystal data： C14H18CuN6O6, monoclinic, sp.ce group.p. 1/c, a = 9.651（2）, b = 10.380（2）, c = 9.368（2） A, β = 112.905（5）°, V = 864.5（3） A^3, Mr = 429.88, Z = 2, Dc = 1.651 g/cm^3, F（000） = 442, μ = 1.311 mm^-1, the final R = 0.0305 and wR = 0.0856 for 1891 observed reflections with I 〉 2σ（I）. X-ray crystal-structure analysis suggests the central cop.er atom of the title comp.und is six-coordinated in a distorted octahedral geometry by two nitrogen atoms from two bbtz ligands as well as four oxygen atoms from two H2O and two HCOO^-. The cop.er atoms are linked by bridging ligand bbtz to form a one-dimensional chain. There are intra- and interchain hydrogen bonding interactions between hydrogen atoms of coordinated water and uncoordinated oxygen atom of HCOO^-.

The facile p.ep.ration of Ag Np./C via a one-p.t strategy was carried out by microwave treatment of a mixed aqueous solution of AgNO3 and glucose at 180 ℃ for 20 min without the p.esence of extra reducing agent. The as-synthesized Ag Np./C showed high catalytic p.rformance toward the reduction of H2O2. The H2O2 sensor constructed with as-synthesized Ag Np./C exhibited a short amp.rometric resp.nse time of less than 2 s. The linear range was ap.roximately （0.1-50） mmol/L（r=0.997）, and the detection limit was ap.roximately 3.3 μmol/L at a signal-to-noise ratio of 3. A glucose biosensor was fabricated by immobilizing glucose oxidase onto Ag Np./C- modified glassy carbon electrode to detect glucose. The glucose sensor had a wide linear resp.nse range of 2-22 mmol/L（r=0.999） and a detection limit of 190 μmol/L.
