Film coating is an essential unit operation in tablet manufacturing. Most tablet dosage forms in the market are film coated. The main purpose for coating of immediate release film dosage form is to provide colour identification, to enhance the stability, taste masking. It is also noted that film coating can improve the processibility and handling during pharmaceutical manufacturing and is the m...

The hydroxyapatite layer was deposited on the commercial magnesium alloy of AZ91 by electrophoretic deposition route, and corrosion behavior applied layers studied polarization electrochemical impedance spectroscopy at Simulated Body Fluid (SBF) solution. best resistance improvement obtained for sample synthesized 40 V within 4 minutes. Also, morphology coated samples atomic force microscopy (A...

A technique of protein electrophoresis suitable for routine use which ensures good separation of the prealbumin fraction is described. The clinical value of visually estimating this protein fraction from the electrophoretic strip is shown with reference to 134 cases. Low levels of prealbumin were found to be associated with liver disorders, malignancy, collagen diseases, congestive cardiac fail...

Researchers have been focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the Electrochemical Impedance Spectroscopy (EIS) method. EIS is a technique used for evaluating coating permeability or barrier performance based on the electrical imped...

Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...

This chapter reviews the novel fabrication process of continuous SiCf /SiC composites based on electrophoretic deposition (EPD). EPD process is very effective for achieving relatively homogeneous carbon coating with the thickness of several tens to hundreds nanometers on SiC fibers. Carbon interface with the thickness of at least 100 nm formed by EPD acts effectively for inducing interfacial de...

This work addresses two ways of loading proteins on microchannel surfaces for immunoassay applications: the "stop-flow" and the continuous flow processes. The "stop-flow" method consists of successive static incubation periods where the bulk solution depletes upon the adsorption process. In the present paper, a multi-step "stop-flow" protein coating is studied and compared to a coating under co...

Abstract Textile-based microfluidics offer new opportunities for developing low-cost, open surface-assessable analytical systems the electrophoretic analysis of complex chemical and biological matrixes. In contrast to fluidic transport in typical chip-based enclosed capillaries where direct access sample zone during is a real challenge. Herein, we demonstrate that selectivity could be easily ma...
