2Ultra-high-molecular-weight polyethylene — (UHMWPE or sometimes shortened to UHMW), also known as high modulus polyethylene (HMPE) or high performance polyethylene (HPPE), is a subset of the thermoplastic polyethylene. It has extremely long chains, with molecular weight numbering in the… …
3Ultra high molecular weight polyethylene — (UHMWPE), also known as high modulus polyethylene (HMPE) or high performance polyethylene (HPPE), is a subset of the thermoplastic polyethylene. It has extremely long chains, with molecular weight numbering in the millions, usually between 2 and… …
4Fault friction — describes the relation of friction to fault mechanics. Rock failure and associated earthquakes are very much a fractal operation (see Characteristic earthquakes). The process remains scale invariant down to the smallest crystal. Thus, the… …
5Entropy (arrow of time) — Entropy is the only quantity in the physical sciences that picks a particular direction for time, sometimes called an arrow of time. As one goes forward in time, the second law of thermodynamics says that the entropy of an isolated system can… …
6Maxwell–Stefan diffusion — The Maxwell–Stefan diffusion (or Stefan–Maxwell diffusion) is a model for describing diffusion in multicomponent systems. The equations that describe these transport processes have been developed independently and in parallel by James Clerk… …
7Photoconductive atomic force microscopy — (pc AFM) is a scientific technique.. Multi layer photovoltaic cells have gained popularity since mid 1980s.[1] At the time, research was primarily focused on single layer photovoltaic (PV) devices between two electrodes, in which PV properties… …
8austausch coefficient — ▪ physics also called exchange coefficient, eddy coefficient , or eddy diffusivity in fluid mechanics, particularly in its applications to meteorology and oceanography, the proportionality between the rate of transport of a component of …
9Ultrasound — Not to be confused with Supersonic .Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy,… …
