To eliminate hazardous hexavalent chromium from a brass wire-mill waste, hydrogen peroxide was examined In place of chromic acid for pickling, first in bench-scale tests and then in plant tests. Nthough the elimination of chromic acid requires more rigid control of the ~ wastewater treatment operation and increases the zinc content of the waste-treatment effluent, the economic benefit of substi...
CdTe film was deposited using the electrophoretic deposition technique onto an ITO glass at various bath temperatures. Four batch film compositions were used by mixing 1 to 4 wt% concentration of CdTe powder with 10 mL of a solution of methanol and toluene. X-ray Diffraction analysis showed that the films exhibited polycrystalline nature of zinc-blende structure with the (111) orientation as th...
Background: This study was conducted to assess the accuracy of dose calculation near the air-phantom interface of a heterogeneous phantom for Acuros XB (AXB) and Anisotropic Analytical Algorithm (AAA) algorithm of a 6-MV flattening-filter-free beam, compared with film measurements. Materials and Methods: A phantom included air gap was ...
External electric field control of topological surface states (SSs) is significant for the next generation of condensed matter research and topological quantum devices. Here, we present a first-principles study of the SSs in the magnetic topological insulator (MTI) Cr-doped Bi2Se3 under external electric field. The charge transfer, electric potential, band structure and magnetism of the pure an...
The conductivity and density of chromic acid solutions were determined (<*r concentrations up to 10 molar (1,000 g/1 of Cr03 ). The density is practically a linear function of concentration. The conductivity increases to a maximum at about 5 molar and then decreases. CONTENTS Page
We propose a new A-film-enhanced fringe field switching (A-FFS) liquid crystal display whose required dΔn value is only λ/4, which is one-half of a conventional FFS. Fast response time can be achieved by either decreasing the cell gap (d) or choosing a low birefringence (Δn) and low-viscosity liquid crystal. The effect of dΔn mismatch between A-film and FFS cell on contrast ratio is analysed. B...
