Maleic anhydride-grafted carbon fiber (CF- g-MAH) was prepared by a solid-phase grafting method. The rheological behavior, morphology, mechanical properties, and nonisothermal crystallization behavior of pure poly(ethylene terephthalate) (PET) and PET/CF and PET/CF- g-MAH composites were investigated. The rheological analyses and mechanical tests show that the addition of CF or CF- g-MAH increased the complex viscosity and mechanical properties of PET. The morphology observations confirm that the introduction of the MAH group on the surfaces of the CF enhanced the interactions between the CF and PET, resulting in the fine dispersion of CF- g-MAH in the PET matrix. In addition, the analyses of the nonisothermal crystallization behavior of pure PET and the PET/CF and PET/CF- g-MAH composites show that CF or CF- g-MAH can act as a heterogeneous nucleating agent in PET and accelerate its crystallization. Compared to CF, CF- g-MAH is a more effective nucleator for PET.

AbstractWe have investigated solid phase crystallization behavior of the MBE grown amorphous Si1-xGex (x=0 to 0.53) layers using x-ray diffractometry and transmission electron microscopy (TEM). It is found that the thermal budget of the solid phase crystallization of the film is significantly reduced as the Ge concentration in the film is increased. In addition, we find that the amorphous Si film crystallizes with a strong (111) texture while the Si1-xGex alloy film crystallizes with a (311) texture suggesting that the solid-phase crystallization mechanism is changed by the incorporation of Ge. TEM analysis of the crystallized film shows that the grain morphology of the pure Si is an elliptical or a dendrite shape with a high density of microtwins in the grains while that of the Si0.47 Ge0.53 alloy is more or less equiaxed shape with a much low density of crystalline defects in them.

Immunoelectron microscopy (IEM) applied to rapid virus diagnosis offers a more sensitive detection method than direct electron microscopy (DEM), and can also be used to serotype viruses. One of several IEM techniques is that introduced by Derrick in 1972, in which antiviral antibody is attached to the support film of an EM specimen grid. Originally developed for plant viruses, it has recently been applied to several animal viruses, especially rotaviruses. We have investigated the use of this solid phase IEM technique (SPIEM) in detecting and identifying enteroviruses (in the form of crude cell culture isolates), and have compared it with a modified “SPIEM-SPA” method in which grids are coated with protein A from Staphylococcus aureus prior to exposure to antiserum.

Enterically transmitted non-A, non-B hepatitis (ET-NANBH) is a type of hepatitis which is increasingly becoming a significant world health concern. As with hepatitis A virus (HAV), spread is by the fecal-oral mode of transmission. Until recently, the etiologic agent had not been isolated and identified. We have succeeded in the isolation and preliminary characterization of this virus and demonstrating that this agent can cause hepatic disease and seroconversion in experimental primates. Our characterization of this virus was facilitated by immune (IEM) and solid phase immune electron microscopic (SPIEM) methodologies.Many immune electron microscopy methodologies have been used for morphological identification and characterization of viruses. We have previously reported a highly effective solid phase immune electron microscopy procedure which facilitated identification of hepatitis A virus (HAV) in crude cell culture extracts. More recently we have reported utilization of the method for identification of an etiologic agent responsible for (ET-NANBH).
