Evaporation and Sublimation

Subroutines for some plasma surface interaction processes: physical sputtering, chemical erosion, radiation enhanced sublimation, backscattering and thermal evaporation

A suite of FORTRAN subroutines/functions to generate data using empirical formulas for physical sputtering of monoatomic targets for any elemental incident ion (atom), chemical erosion of graphite, Radiation Enhanced Sublimation (RES) of graphite, the number and energy backscattering coefficients for any elemental incident ion (atom) on a compound target and thermal evaporation of graphite is p...

Freud and Nietzsche on Sublimation

The notion of sublimation is essential to Nietzsche and Freud. However, Freud’s writings fail to provide a persuasive notion of sublimation. In particular, Freud’s writings are confused on the distinction between pathological symptoms and sublimation and on the relation between sublimation and repression. After rehearsing these problems in some detail, it is proposed that a return to Nietzsche ...

A sublimation heat engine

Heat engines are based on the physical realization of a thermodynamic cycle, most famously the liquid-vapour Rankine cycle used for steam engines. Here we present a sublimation heat engine, which can convert temperature differences into mechanical work via the Leidenfrost effect. Through controlled experiments, quantified by a hydrodynamic model, we show that levitating dry-ice blocks rotate on...

Freud's Aesthetics: Matriarchy, Sublimation and the Surreal

Sigmund Freud is only occasionally referenced as a theorist of art. Given his general theory however, its applicability can easily extend to art, and this was a significant part of his own writing. Aesthetics for Freud is a form of wish fulfilment. It is a way to deal with the struggle of the transition from the pleasure to the Reality Principle. This conversion lies at the root of much persona...
