The mixture of a medical and legal approaches in dealing with crimes used in the United States today had its beginning in England in the 12th century, when King Richard I instituted the Office of the Coroner. Even though the coroner’s main duty was to maintain a record of all criminal matters in the county, [...]

The electron microscope is a kind of microscope that uses electrons to generate an image of the target. It has much advanced magnification or resolving power than a normal light microscope, up to two million times, allowing it to view smaller objects and details. Electron Microscopes (EMs) operate precisely as their optical counterparts with the [...]

The Scanning Electron Microscope (SEM) is a type of electron microscope capable of producing high-resolution images of a sample surface. SEM images have a characteristic three-dimensional appearance and are useful for judging the surface structure of the sample. SEM uses an electron beam generated in a vacuum to magnify very small objects. It is an [...]

Scanning Electron Microscopes are predominantly being used during forensic investigation of a certain incident in order to establish the details of such event and the persons and things involved. How it has evolved is due to the fact that forensic examination of substances found at a crime scene can often establish the presence of the [...]

Scanning Electron Microscopes are patterned after reflecting light microscopes and yield similar information in terms of topography, morphology, composition and crystallographic information.
In topography, the surface skin of an object and its texture. The detectable features are restricted to a few manometers. In morphology, the shape, size and arrangement of the particles making up the object [...]

Scanning electron microscope is an astonishing instrument for seeing the unnoticed realm of micro-space. Regular light microscopes make use of a series of glass lenses to bend light waves and generate a magnified image. The SEM displays extremely thorough 3-dimensional images at much advanced magnifications than is viable with a light microscope. The images produced [...]

In the early 20th century Nikola Tesla had the idea of shooting high-energy electron beams in the atmosphere and this was later used in experimental electron beam welders, pressure gauges and probably weapons tests. Manfred von Ardenne (1940), founder of the scanning electron microscope (SEM), imaged specimens in a gaseous environment by passing a high-energy [...]
