density as well their good environmental stability as in the case of polyaniline (PAN). In the present work ‚ in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to synthesize polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites‚thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer and X-ray diffraction . The morphology of these composites was studied by scanning electron microscopy. (Received

An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

provide support for the paint and the solvent is what makes the paint into a liquid. 3. What are polymers? Polymers are substances that are made up of many atoms that form in repeating patterns. 4. What is a scanning electron microscope? What are its advantages? The scanning electron microscope is a microscope that works by shooting beams of electrons at the slide and recording the emissions of the electrons. One advantage is that it has much better magnification than other microscopes!

Nanogenerator is a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves‚ mechanical vibration or blood flow. Based on arrays of vertically-aligned zinc oxide nanowires that move inside a novel “zig-zag” plate electrode‚ the nanogenerators could provide a new way to power nanoscale devices

Environmental racism is an extreme situation which affect people all over the world because a multitude of innocents are dying. Many people are being affected‚ but whom exactly?

Notes for WK2 – 10 September Lesson 1 * State the resolution and magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object
