Free-energy perturbation (FEP) is a method based on statistical mechanics that is used in computational chemistry for computing free-energy differences from molecular dynamics or Metropolis Monte Carlo simulations. The FEP method was introduced by Robert W. Zwanzig in 1954. [1]

Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...

N.B. Pilling and R.E. Bedworth [2] suggested in 1923 that metals can be classed into two categories: those that form protective oxides, and those that cannot. They ascribed the protectiveness of the oxide to the volume the oxide takes in comparison to the volume of the metal used to produce this oxide in a corrosion process in dry air.
The linear generator also allows the control of the resistance force, and therefore a better control of the piston's movement and of the reaction. The total efficiency (including mechanical and generator) of free-piston linear generators can be significantly higher than conventional internal combustion engines and comparable to fuel cells.
Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP.< [1] Its physical appearance is grey needles. Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly. [1] Iron phosphide reacts with moisture and acids producing phosphine (PH 3), a toxic and pyrophoric gas.
