Metallic bearings Steelair’s bimetallic bearing represents advancement in bearing technology and it can be assembled, accustomed or soldered into place. Along with high load capacity and good fatigue properties, it is also an excellent wear-resistant material. The bimetallic bearing is the composite of low friction copper alloy and is perfect for use when provided with excellent requisite strength and the finest carrying capacity by means of derived remains and secondary wedging technology. It…

“Consumers are wasting billions of dollars a year on billions of gallons of bottled water in large part because advertising spin has led them to believe that water in a bottle is safer or better than tap water” (“Why Tap Water Is Best”). Tap water against bottled water is a tremendous feud today in our environment. An ongoing argument is occurring between which one helps your environment, pocketbook, or health. A more variety of studies shows that tap water is better than bottled water. To…

As one of the two-dimensional (2D) materials, m-MoS2 exhibits promising electronic properties such as high carrier mobilities (200 cm2V-1s-1) at room temperature, high current on/off ratio (1×108) and ultralow standby power dissipation [7,8]. Based on atomic layer MoS2, thin film transistors…

[Qin Yi, Fan Hui Li et.al, 2012] using Dimethyl terephthalate instead of part of phthalic anhydride prepared Polyester resin with the excellent flexibility. He then used sol-gel technology to prepare silicone-modified polyester resin. The properties of the coting film, such as hardness, flexibility, solvent resistance and adhesion were studied and optimized. When compared with commercially available coloured polyester coating SM 3911, the flexibility, adhesion, rigidity , MEK resistance and…

magnesium as the major alloying elements constitute a group of non heat treatable alloys (AA5XXX series) used for structural materials in automotive, aircraft and marine applications. Welding of this alloy using conventional technique leads to vaporization of Magnesium, which causes compositional changes in the weld seam [9]. Hence, to regain the Mg content (from AA5XXX series materials) FSW may be the feasible technique to overcome this…

IZOD Impact Test of Notched Polymer Introduction The IZOD impact test is a method used to determine the impact resistance of materials. The main objective of this experiment is to measure the impact strength of three specimens’ material by measuring the amount of the energy required to cause the material to fracture, using Avery Denison 6709 IZOD impact tester. Materials and Methods Apparatus: Three specimens with a machined 45° notch (V-Notch) at room temperature {Polycarbonate, Polyamide…

the above results and discussion, Knuckle joint was design for 52860 N axial load by theoretical calculation. From theoretical calculation we applied that load for analysis in NX CAD software and we obtained result for steel and cast iron G25 materials and results are shown in figures. CHAPTER: 2 TYPES OF MECHANICAL JOINT Normally, Mechanical joints are…

The SLS process uses powder materials to produce 3D solid parts from CAD file. After the CAD data is uploaded to machine computer in the Stereo lithography file format, the process of sintering starts. From figure 1, it can be observed that SLS system contains three chambers. There are…

shows the chip shapes formed during the milling of the MMCs. The composite chips had large radii, and were semi-circular helical type and saw-toothed. The SiC foam reinforcement in the Al matrix diminished the ductility and converted the workpiece material for generating saw-toothed and segmented-type…

Kitty Hach – Darrow was a mother. Chemical entrepreneur marketing trailblazer and pilot. She started college at Iowa state university to become a home economics teacher but was inspired by a chemist in the department who lead many young women into chemical profession. Another influence in to her chemical profession was her soon to be husband Cliff Hach. Water purifying has come a long way since Kitty’s discovery; we now have water filters and plants that filter water for us. Also we have…
