Abstract: The nano-CaCO3/Acrylonitrile-Butadiene-Styrene (ABS) composites were prepared by
melting-blend with the single-screw extruder. The mechanical properties of the nanocomposites and
the dispersion of nano-CaCO3 were investigated by means of transmission electron microscopy
(TEM) and mechanical tests. The micro structure of the fracture section of the nanocomposites was
analyzed by means of scanning electron microscopy (SEM). The results show that not only the
impact property but also the rigidity property and the bending modulus of the system have been
increased evidently by added modificated nano-CaCO3. However, the tensile strength of the
nano-composites has a little decreased by added the modificated nano- CaCO3. The modificated
nano-CaCO3 has been dispersed well in the matrix in the nanometer scale. The micro structure of
the fracture section of the nanocomposites proved that when the composites have been impacted,
the modificated nano-CaCO3 particles have taken an action of initiating and terminating crazing
(silver streak), which can absorb more impact energy than the pure ABS resin. Compared with the
pure ABS resin material, the notched impact strength of the nano-CaCO3/ABS composites added 2
percent hundred resin (PHR) modificated nano-CaCO3 reach 36.77 kJ/m2, which have been
increased up to 44%. At the same time, the rigidity of the nanocomposites has also been enhanced
by 23.5% which is increased from 28.16N to 34.87 N.

Abstract: Flexure hinge is widely used in the field of MEMSElliptical flexure hinge with the
advantages and little disadvantage of rectangular and circular notch, has broad prospect in the field
of MEMS and NEMSAccording to the basic theory of material mechanics and calculus, angular
stiffness and linear deflection was deduced on the elliptical flexure hinge, and the analytical
equations are attainedAt the same time, angular and linear deflection of right elliptical flexure
hinge, which is popular used flexure hinge, is presentedEquations of right elliptical flexure hinge,
is exact and more concise in expression than that of Smith, so it is more convenient to use it in
calculating and analyzing elliptical flexure hinge and elliptical flexure hinge mechanisms

Abstract: Fracture surface and surface of two kind of membrane of antibacterial bone china, which
includes 3% and 5% of weight of composite phosphate containing rare earth respectively, were
characterized by SEM and nanoindenter, respectively. Nanohardness and nanoscale friction
coefficients were measured by nanoindenter. Friction coefficients were conducted at the maximal
load being 300un,500un,1000un and scratching speed 15um/s, 0.75um/s, 0.5um/s, respectively. The
nanohardness and friction coefficients of ceramic membrane including 3% and 5% of rare earths are
2.03GPa,0.18282 and 8.54GPa,0.051998, respectively. The two kind of ceramic membrane has
stable nanotribology property. Obvious plastic flow and pile-up scratch impression of ceramic
membrane including 3% rare earths is observed by AFM in situ imaging, but scratch impression of
5% has no plastic flow and take on the sink-in topography. Nanohardness and friction coefficients
of this two kind of ceramic membrane have strong relationships each other but weak relations with
elastic modulus.

Abstract: One of weak point of PS/clay nanocomposite is the lack of interfacial adhesion between clay and
polystyrene matrix. In this research, the radical sites on the clay surface were induced via the
plasma technique. The optimum condition for this process was investigated and used to treat
bentonite before grafting styrene on clay structure. The increase of basel-spacing of clay was not
noticeable from XRD spectra, but the FT-IR spectra showed characteristic peak of polystyrene
implied that the styrene grafting was occurred on the outer surface of the clay. The impact strength
is quite improved, especially for the higher ratio of styrene/clay during the grafting step.

Abstract: Nanometer-sized silicon oxide can be used in water flooding in oil development because
of its super hydrophobic and oleophilic ability. In oil reservoir, these nanomaterials are usually
physically adsorbed on the surface of sandstone and improve the wettability and water phase
permeability. Therefore flow resistance is reduced and water adsorbing index is increased. Both
experiment and application results show that nanometer silicon oxide is an excellent material used
for water flooding, water injection pressure and ability of adsorping water in low permeability
reservoir. The paper analysis the mechanism of increasing water adsorbing index and discuss the
conditions for selecting water injection well.
