Julius Lothar Meyer (19 August 1830 – 11 April 1895) was a German chemist. He was one of the pioneers in developing the earliest versions of the periodic table of the chemical elements . The Russian chemist Dmitri Mendeleev (his chief rival) and he had both worked with Robert Bunsen .
Universal curve for the electron inelastic mean free path in elements based on equation (5) in. [1] If a monochromatic , primary beam of electrons is incident on a solid surface, the majority of incident electrons lose their energy because they interact strongly with matter , leading to plasmon excitation, electron-hole pair formation, and ...

Diffusional transformations like austenite transforming to a cementite and ferrite mixture can be explained using the sigmoidal curve; for example the beginning of pearlitic transformation is represented by the pearlite start (P s) curve. This transformation is complete at P f curve. Nucleation requires an incubation time.
Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.
