Pixel Computer Aided Design (CAD) Method to Understand Mass Measurements, Imaging in Milli, Micro and Nanometer Resolution

In this article we measure the steady mass for our samples polyvinyl chloride and polyethylene. The constant mass is achieved when the acrylic box is used to shield the precision mass balance. The mass of our sample 1 polyvinyl chloride is 160 mg. Our sample 1 polyvinyl chloride is thin film of length 5.5 mm, width 7 mm and thickness 3.2 mm. The density of the polyvinyl chloride is 1300 kg/m3 in agreement with the literature. The stream flow is blocked when the acrylic shield is used. We observe fluctuations in the mass from 320 mg to 560 mg when there is no acrylic shield. The mass of our sample 2 polyethylene is 120 mg and the density is 893 kg/m3 with the acrylic shield. The mass of the polyethylene membrane material fluctuates from 60 mg to 350 mg without the acrylic shield. The geometry of our sample 2 polyethylene is length 14 mm, width 12 mm and thickness 0.8 mm. Further we build pixel computer aided design (CAD) model to correlate with the chemical elements in the periodic table towards exact match with the optical camera image of our two samples that are polyvinyl chloride and polyethylene. Furthermore we build the model to exact match to the scanning electron microscopy (SEM) in micrometer and nanometer resolution to both samples. The chemical periodic table elements are obtained from energy dispersive spectroscopy (EDS). The study of membrane materials can find applications towards energy and thermal management coolants.
