  • Relationship between Physico-Chemical Property of blood and cerebrovascular compliance
    Journal of Shanxi Medical University, 2001
    Co-Authors: Hou Yu
    Abstract:

    Objective To review the relationship between Physico-Chemical Property of blood and cerebrovascular compliance. Method The blood velocity of middle cerebral artery(MCA) in patients with cerebral infarct was observed with transcranial Doppler(TCD),and the pulsibility index(PI) was caculated:PI=( V s- V d)/ V m.( V s is systolic peak flow, V d is end diastolic flow, V m is mean peak flow).Then,the object was divided into two groups:group PI≤1 and group PI1.Meanwhile,blood lipid,blood rheology and fibrinogen (Fig) were compared between two groups. Result TC,TG,ApoB,LDL,Fig and blood rheology of group PI1 were signigficantly increased compared with group PI≤1 (P0.05).Conclusion cerebrovascular compliance is influenced by the physico chemical Property of blood.

  • Comparative research on Physico-Chemical properties of domestic BaCO_3 of electronic grade
    Electronic Components and Materials, 2008
    Co-Authors: Shang Shao-ming
    Abstract:

    The evolution of Physico-Chemical Property of domestic electronic grade BaCO3 was compared by particle size analysis,shape microanalysis,AAS and etc.The results show that the evolution of the shape,dispersivity and acid radical content of samples are not optimistic.The Physico-Chemical Property of product,especially the specific surface area and nitrate content show great fluctuation,which need the manufacturer and user to pay more attention on.It is proposed that the specific surface area and nitrate content of product should be added into Physico-Chemical index and the quality of product should be strengthening controlled.

  • Heterogeneous photocatalysis by solid polyoxometalates
    Journal of Molecular Catalysis A: Chemical, 2007
    Co-Authors: Yihang Guo, Changwen Hu
    Abstract:

    This paper reviews a series of novel water-tolerant polyoxometalate-containing composite photocatalysts such as amine-functionalized mesoporous silica/anatase titania impregnated with transition metal substituted polyoxometalates, bimodal porous polyoxotungstate-anatase TiO2 nanocomposites, Fe-polytungstate-silica-structured fabrics, monovacant Keggin unit-silica/titania composite films, and highly ordered macroporous monovacant Keggin unit-titania composite films, including their design, preparation, optical absorption Property, surface Physico-Chemical Property, morphology, and heterogeneous photocatalytic behaviors. Emphases are addressed on the efficient photocatalytic activity of as-prepared solid polyoxometalates in the near UV- and/or visible-light region and easier recovery of the catalyst from the reaction system. © 2006 Elsevier B.V.

  • The preparation and structure of salty ice VII under pressure
    Nature Materials, 2009
    Co-Authors: Stefan Klotz, Livia E. Bove, Thierry Strässle, Thomas Hansen, Antonino M. Saitta
    Abstract:

    It is widely accepted that ice, no matter what phase, is unable to incorporate large amounts of salt into its structure. This conclusion is based on the observation that on freezing of salt water, ice expels the salt almost entirely as brine. Here, we show that this behaviour is not an intrinsic Physico-Chemical Property of ice phases. We demonstrate by neutron diffraction that substantial amounts of dissolved LiCl can be built homogeneously into the ice VII structure if it is produced by recrystallization of its glassy (amorphous) state under pressure. Such 'alloyed' ice VII has significantly different structural properties compared with pure ice VII, such as an 8% larger unit cell volume, 5 times larger displacement factors, an absence of a transition to an ordered ice VIII structure and plasticity. Our study suggests that there could be a whole new class of 'salty' high-pressure ice forms.
