In the present article we report a study on some Nanoparticles Materials synthesized by sol-gel process to set up a cleaning system to remove a wide range of different types of organic and inorganic materials from the surface of the wall paintings

values of the thermophoresis parameter enhances the velocity‚ temperature and concentration fields of the flow. This is due to the imbalanced ratio of the heat capacity of nanoparticles and base fluids. In fact‚ as the thermophoresis increases‚ nanoparticles eject themselves from the wall‚ which leads to increase in the nanoparticle volume fraction. It is also noticed that the temperature field of Oldroyd-B fluid is highly influenced due to variation in the thermophoresis

About Nanotechnology Email | Print Imagine being able to observe the motion of a red blood cell as it moves through your vein‚ or being able to watch as a type of white blood cell (called a "T-cell") destroys an invading microbe by engulfing it. What would it be like to observe the vibration of molecules as the temperature rises in a pan of water? To observe sodium and chlorine atoms as they get close enough to actually transfer electrons and form a salt crystal? New scientific tools‚ developed

4002DFPHAR PHYSICAL PHARMACEUTICS Particle Size Analysis The study of particle dimensions is important in many areas of manufacture and technology. Many solid materials are at some point powder or granular in form e.g. foods (grain‚ flour‚ sugar)‚ ceramics and building materials (sand and cement). In pharmaceutical development and manufacture‚ particle size greatly influences physical properties such as powder flow‚ powder mixing‚ drug dissolution‚ deposition from inhaler devices and the stability

things because of drawbacks of such devices .Scientists on the moment have actually found that some of nanoparticles on which they are working can go through human skin .This could permanently damage our skin cells ‚ causing cancer. If we are using nanoscience in everyday life in future ‚ then it could affect the environment very much ‚ so we don’t have that much advanced facilities to stop nanoparticles from going through them .Nanotechnology can make our life luxurious ‚ but we may even lose an identity

Vaccines represent one of the great achievements in public health. A turning point in the war against pathogenic infection occurred over 200 years ago when Edward Jenner used cowpox to elicit protective immune responses against a devastating outbreak of smallpox. Since then‚ the use of safe and effective vaccines to prevent infection has become a fundamental aspect of modern medicine. While many vaccination campaigns have been successful‚ the constant emergence‚ and re-emergence‚ of pathogens challenges
