Coordination complex of a copper cyanurate(Cu(Ⅱ)-CA) was transformed into coordination polymers upon the stimulus of extra Cu(Ⅱ) through “directed Ostwald ripening”. By increasing the molar ratio of Cu(Ⅱ) to CA, we obtained two coordination polymers with selective coordination sites: Cu(Ⅱ)-κ N(HCA)κ NCu(Ⅱ) and Cu(Ⅱ)-κ N(HCA)κ O-Cu(Ⅱ), which display disparate magnetic interactions.

A rich assemblage of planktonic foraminifera has been studied from an outcrop of the Gurpi Formation, the hydrocarbon source rock in the southwest Iran, Deh Dasht area（Kuh-e Siah anticline）. Based on the distribution of the planktonic foraminifera, eight biozones have been recognized that included：Dicarinella concavata Interval Zone（Earliest Santonian）, Dicarinella asymetrica Total Range Zone（Santonian to Earliest Campanian）, Globotruncanita elevata Partial Range Zone（Early Campanian）, Globotruncana ventricosa Interval Zone（Middle to Late Campanian）, Radotruncana calcarata Total Range Zone（Late Campanian）, Globotruncanella havanensis Partial Range Zone（Late Campanian）, Globotruncana aegyptiaca Interval Zone（Late to latest Campanian）, Gansserina gansseri Interval Zone（Latest Campanian to Early Maastrichtian）. These biozones indicates that the Gurpi Formation deposited during the Early Santonian- Early Maastrichtian. These biozones are compared to the most standard biozones defined in Tethysian domain. Based on distribution of morphotype groups of planktonic foraminifera, planktonic to benthic ratio（P/B） and content of carbonate, nine third-order sequences are recognized.

Nickel modified NiOOH electrodes were used for the electrocatalytic oxidation of ethanol in alkaline so lutions. The electro-oxidation of ethanol in a 1 mol/L NaOH solution at different concentrations of ethanol was stu died by ac impedance spectroscopy. Electrooxidation of ethanol on Ni shows negative resistance on impedance plots. The impedance shows different patterns at different applied anodic potential. The influence of the electrode potential on impedance was studied and a quantitative explanation for the impedance of ethanol oxidation was given by means of a proposed mathematical model. At potentials higher than 0.52 V（vs. Ag/AgCl）, a pseudoinductive behavior was observed, but at those higher than 0.57 V, impedance patterns were reversed to the second and third quadrants. The conditions required for the reversing of impedance pattern were delineated with the impedance model.

The Soursat metamorphic complex （SMC） in northwestern Iran is part of the Sanandaj- Sirjan metamorphic belt. The complex is composed of different metamorphic and plutonic rocks, but is dominated by metapelites composed of garnet, staurolite, kyanite, fibrolite, cordierite, and andalusite. Porphyroblasts in schists have the same fabric, and three stages of schistosity are present. The internal schistosity （Sn） inclusion trails are also offset by conjugate sets of extensional schistosity （Sn＋l） and a second （Sn＋2） that crenulates （Sn＋l）. Polyphase metamorphisms are present in the complex. Garnet, staurolite, kyanite, and fibrolite assemblage preserves conditions during the M1 metamorphic event. This assemblage yields a P-t estimate of 645±11℃ and 6.5±0.5 kbar. Other samples of the central part of SMC contain cordierite and andalusite （M2） overgrowth that yields a P- t estimate of 532±33℃ and 2.1±1.1 kbar.
