Differences in (atmospheric) pressure during transport do not only occur in planes. The pressure in the room can also change during truck transport, for instance in the mountains. Especially airtight packagings are affected by changes in atmospheric pressure. A low pressure test has been developed to simulate changes in pressure in order to test whether the […]

The manufacture of arms and ammunition is presently regulated under a licensing system established by the Arms Acts (1959) and Arms Rules (1962) and is under Government domain. The manufacturing of Small Arms for armed forces/paramilitary forces/police, are confined to the Department of Defence Production. Even after liberalization of the Indian economy and removal of

In semiconductor manufacturing plasma ashing is the process of removing the photoresist (light sensitive coating) from a wafer. Using a plasma source, a monatomic (single atom) substance known as a reactive species is generated. Oxygen or fluorine is the most common reactive species. The reactive species combines with the photoresist to form ash which is

Basic concept : Microwave Plasma Chemical Vapor Deposition for Diamond deposition MPCVD is a very important method that has been frequently used for diamond deposition. Here, microwave plasma is used to activate the hydrocarbon feed and dissociate molecular hydrogen. Typically, 2.45 GHz is used as an excitation source. Microwave plasma oscillates electrons, which in turn produces ions by colliding with gas

Surface wettability plays an important role in determining the function of a wound dressing. Dressings with hydrophobic surfaces are suitable for bacterial adsorption, however, a hydrophilic surface is needed to improve cell attachment for most anchorage-dependent cell types. Furthermore, the hydrophobicity/hydrophilicity of the surface can be used to direct cellular processes such as cell initial
In the past several years, Cyclic Corrosion Testing, or CCT, has become a common practice in the automotive industry. Designed to accelerate corrosion in a laboratory environment, CCT tests how materials used in the auto sector will react to the weather, stimuli, and conditions encountered on the road. This, in turn, allows manufacturers to prepare

It has been indicated that under conditions of glow discharge, ion bombardment of the cathode will occur. This results in the erosion of the cathode material and is termed plasma sputtering, with the subsequent omni-directional deposition of the sputtered atoms forming coatings of the original cathode material on the surface of the sample and work

Force = Mass x Acceleration This equation is the basis for selecting sizing shakers and determining if your shaker can perform a specific shock or vibration test. The premise is this: the more mass you put on your shaker, the less acceleration the shaker can produce. And vice-versa: the less mass you put on your

Climatic chamber is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components. These chambers can be used: as a stand-alone test for environmental effects on test specimens as preparation of test specimens for further physical tests or chemical tests as environmental conditions for conducting testing of
Industrial X- Ray machine: Industrial Radiography is a modality of NDT that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. This machine plays an important role in the science and technology needed to
