of medium 2 θi = angle of incidence θt¬ = angle of transmission Rs = Reflected intensity at S-Polarization Rp = Reflected intensity at P-Polarization Antireflection Coating Generation of charge carriers through absorption of photons is the electrical current generating mechanism of solar…

The coating is very tough and easily stands up to the salts and other chemicals that your car brings in from the street. Unlike porous concrete, the coating's smooth finish allows for quick and easy cleaning. It also protects the floor from grease, oil, and other fluids from your car and equipment stored in your garage. The Problem with DIY Garage Floor Coating Applying a garage floor coating that will last for years, requires work, attention to…

and discussion 3.1 Microstructural characterization The Roman spectrum of Cr-DLC coating was shown in Fig.1. The overlapped D peak and G peaks located at 1363cm-1 and 1564cm-1 were obtained after fitted with Gaussian curves, respectively. It’s well known that the content of the graphite crystal was closely related to the value of ID/IG [22]. And the ratio of intensity between D peak and G peak (ID/IG) of Cr-DLC coating could be calculated by the fitted curve. The value of ID/IG was about 1.98,…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…

Industrial metal coatings and abrasion resistant coatings accounted for $6.8 billion in revenue in 2014. In fact, automotive refinish coatings are the largest segment of the paint industry, just ahead of industrial maintenance coatings, with a revenue of $2 billion in 2014. For those battling rust or looking for wear-resistant coatings, here are some common questions to consider. What causes rust on metal? Rust on metal is caused by surface metal atoms and molecules forming metal oxides in the…

example, people are not obliged to replace their Al2O3-coated kitchen tools due to contamination or damage or corrosion if Al2O3 is used effectively in the anti-corrosion coating of these tools. The Economic Impact of Al2O3 in Anti-Corrosion exaggerated? However, some argue that the economic impacts of Al2O3 in anti-corrosion coating industry is exaggerated and the global demand will not keep growing steadily on these products. But this argument is invalid as the number of population is…

New Detectable Warning Product Offers Streets Resiliency Streets are safer, more visible and resilient with a new liquid lane coating product that merges sustainability with simplicity. Jon Julnes began VANGUARD ADA Systems, a company that produces and installs outdoor surface products, in an attempt to create detectable street warning that worked. As an installer, Julnes found an underlying problem in his line of work: The claims of other detectable warning products in the industry simply were…

INTRODUCTION In last several decades, conventional dosage forms are replaced by oral controlled release preparations due to poor drug efficacy, side effects and frequency of administration due to maximum concentration of drug (Cmax) normally reduced within 1-2 h which may not match with the maximum intensity of disease state. Oral controlled drug delivery system release the drug with constant rate to maintain drug concentration in the human body, regardless of the patient physiological…

Coating pans are less expensive than most other types of pelletization equipment. They are also extremely versatile in that both layering and pellet coating. Coating pans are available in a wide variety of shapes and sizes. Pear, hexagonal, angular, spherical, elliptical, and donut-shaped. Pellet movement is best described as cascading, with maximum turbulence in the centre of the load. Conventional coating pans, however, have significant limitation as…

All samples were preserved in polyethylene trays under refrigerated condition for 16 days. Kirby-Bauer disc diffusion test For determining of bacterial resistance to alginate-LPOS coating, disc diffusion test was conducted. In this procedure, antimicrobial activity of the coating on specific bacteria including Pseudomonas fluorescens NCTC 10038, Escherichia coli NCTC 12241 was investigated. These organism significantly can be found in in chicken meat (Molin and Ternström 1982;…
