One Mn(II) coordination polymer, [Mn(o-(NO2)C6H4COO)2(pyz)(H2O)]n (1), has been synthesized and oxidized with n-Bu4NMnO4 in non-aqueous media to two mixed-valence hexanuclear Mn(II/III) complexes [MnIII2MnII4O2(pyz)0.61/(MeOH)0.39(o-(NO2)C6H4COO)10·(H2O)·{(CH3)2CO}2]·(CH3)2CO (2) and [MnIII2MnII4O2(pyz)0.28/(MeCN)3.72(o-(NO2)C6H4COO)10·(H2O)] (3) (where pyz = pyrazine). All three complexes were...

There are two contents of this article. The first is briefly to review the experiment research on catalysis mechanism Carbon Gasification Reaction-CGR(C+CO2=2CO) from 60s -90s. results show that catalytic phenomenon physical rather than chemical, and catalyst does not participate in chemical reaction. activity selectivity related electronegativity or energy level catalyst. second clarify applic...

The thermal and photo-induced switching properties of the recently published molecular spin crossover complex [Fe(H4L)2](ClO4)2·H2O·2(CH3)2CO () have been investigated in detail through Raman spectroscopy. Magnetometric and single crystal X-ray diffraction kinetic studies within the hysteresis loop have proven its metastable character, which allowed establishing the shape of the true, quasi-sta...

Cytochalasin B, a mold metabolite, has been shown to inhibit cytokinesis and motility (3), morphogenie development (18), endocytosis (5), and the transport of sugars (8-10, 12). I t has also been demonstrated that this drug inhibits the stimuatcd elaboration of extracellular substances from glands-the release of thyroxine from the thyroid gland after stimulation by thyroid-stimulating hormone (...

The catalytic oxidation of CO molecule on a thermodynamically stable Cu4 cluster doped MoS2 monolayer is investigated by density functional theory (DFT) where the reaction proceeds in a new formation order of COOOCO* (O2* + 2CO* → COOOCO*), OCO* (COOOCO* → CO2 + OCO*), and CO2 (OCO* → CO2) desorption with the corresponding reaction barrier values of 0.220 eV, 0.370 eV and 0.119 eV, respectively...
