![]() Royal Society of Chemistry members receive a discount of 15% for this course (membership number required). Scheduled course price: £110 + VAT per delegate For a diffraction grating, the relationship between the grating spacing (i.e. Delegates are able to ask live questions either by using their microphone or by typing into the chat boxes. A diffraction grating reflecting only the green portion of the spectrum from a rooms fluorescent lighting. This course is taught live in a virtual classroom and offers a fully interactive experience, with instrument parts and consumables to see. You will learn about the components of Laser Diffraction Analysis instrumentation, the purpose and principles of data analysis and the different sampling techniques that can be used. This live and interactive online course explains the principles of these techniques, along with some of the industries which use them and their applications. The course is also ideal for analysts or technicians looking for a refresher in these techniques. 31−40.This course provides an introduction to Laser Diffraction Analysis (LDA), aimed at complete beginners. Selecting a diffraction grating in Raman spectroscopy requires a choice from the user on what to prioritise. Morphology and oxidation kinetics of CI engine’s biodiesel particulate matters on cordierite diesel particulate filters using TGA, International Journal of Automotive Technology, Vol. For UV lasers high groove density gratings are recommended, such as 2400 gr/mm and 3600 gr/mm, mainly due to the inherent decrease in spectral resolution when exciting at lower wavelength.

Furthermore, high level of proper particle size (20 nm – 100 nm) contaminated in oil will increase probability of rubbing process. By the way, the too large particle size compared to oil film thickness will escape out and too small particle size will not effect on wear. In conclusion, the appropriate particle size (20 nm - 80 nm of primary particles and 80 nm - 300 nm of agglomerated particles), which is near to oil film thickness between metal surface contacts, is the dominant cause of making wear. Based on tribology test, soot contamination in oil made more wear on tested steel ball and reduced friction during test comparing to the test with fresh oil. Wear roughness in micro-scale was also investigated by high resolution optical microscope and 3D rendering optical technique. The behavior was studied by means of a Four-Ball tribology test with friction and wear measured. Micro-nanostructure of particles were studied by electron microscope. ![]() Soot particle contamination was simulated using carbon black. The characteristics of soot affecting on the abilities of lubricating oil and leading to result in metal wear was studied.
