Why Uranium 238 is not fissile? By contrast, the binding energy released by uranium-238 absorbing a thermal neutron is less than the critical energy, so the neutron must possess additional energy for fission to be possible. Consequently, uranium-238 is a fissionable material but not a fissile material. Is uranium 238 fissile? Unlike uranium-235, it is […]

How do you increase the depth of field on a microscope?
How do you increase the depth of field on a microscope? Place your aperture in front of the microscope lens centering the aperture. For some gross-specimen low-magnification ‘scopes, this is relatively easy since the lens is quite large. The field-stop acts as an outboard aperture to limit the light entering the lens to the centre. […]
What are the mechanical properties of metals?
What are the mechanical properties of metals? Key mechanical properties of metals include: Strength. Ductility and Malleability. Toughness. Fatigue Resistance. Hardness. What is mechanical toughness? In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of material toughness is the amount of energy […]
