The surface accuracy and quality of the mirror blank determine performance optical after coating; therefore, it is crucial to seek a simple effective method for processing. gas jet forming provides new idea, which employs impinge on liquid pool, forms specific curved solidifies it. However, due interface instability that occurred with range velocity, periodical fluctuations appear affect blank....

2014 In this paper, the experimental results describing the substrate bias effect on the Schottky gate capacitance-voltage and the DC current-voltage characteristics of GaAs FET’s (N-type epilayer on semi-insulating Cr-doped substrate) are reported. These results are accounted for by the formation of a double space-charge in the N-layer and in the S.I. substrate in the vicinity of the interface...

This paper concerned with the dispersion of Love wave in a fiber-reinforced medium lying over a heterogeneous half-space. The heterogeneity is caused by the consideration of quadratic variation in density and directional rigidity of lower half-space. The irregularity has been considered in the form of rectangle at the interface of the fiber-reinforced layer and heterogeneous half-space. The dis...

isotherm equation is one of the important scientific bases for adsorbent selection. there are different isotherms that do not account for an adsorbate, different chemisorption geometries on the nanoporous surface. it is interesting to introduce a general isotherm, which considers different chemisorption geometries of an adsorbate on nanoporous surfaces. in this study, an isotherm for non-dissoci...
