Slot die coating technology is currently the most widely used method for production of optical films. The main advantages of this coating method are its ability to pre-determine the product film thickness and to produce uniform film under prolonged operation. In the present study, a laboratory-scale slot die coating equipment was used to investigate the effects of pH, molecular weight and degre...

graph 5100, Micromeritics) and the specific surface area was measured by nitrogen adsorption, the BET-method (ASAP 2000, Micromeritics). The particle size distribution (PSD), a narrow or broad distribution, was determined by using the equation: PSD slope=[75% (ESD)-25% (ESD)]/2.APS, where ESD means equivalent spherical diameter and APS means average particle size. Oil absorption, packing index,...

A new technique for the electron microscope localization of bacterial surface antigens, using unlabeled antisera, has been developed. This technique, called the "immuno-coating reaction" was applied to serological studies of Streptococcus sanguis, using antisera which had been shown to be specific for this species by gel diffusion analysis. The results of the immuno-coating reaction confirmed t...

Seed inoculation with plant growth promoting rhizobacteria (PGPR) is an ideal tool to supply the soil with a high density of beneficial microorganisms. However, maintaining viable microorganisms is a major problem during seed treatment and storage. In this work, an evaluation was made of the effect of bacterial immobilization in nanofibers on the stability (viability and maintenance of benefici...

Fabricating large single crystals with colloidal spheres as building blocks is challenging and of competitive interest. Spin-coating of colloids offers a robust technique, which is highly reproducible in obtaining colloidal crystals even at fast dynamical regimes; however, these crystals are intrinsically polycrystalline due to the axial symmetry of spin-coating. We report a new method that app...

A β-Ta nanocrystalline coating was engineered onto a Ti-6Al-4V substrate using a double cathode glow discharge technique to improve the corrosion resistance and bioactivity of this biomedical alloy. The new coating has a thickness of ~40 μm and exhibits a compact and homogeneous structure composed of equiaxed β-Ta grains with an average grain size of ~22 nm, which is well adhered on the substra...
