Charles E. Weir (September 29, 1911–April 4, 1987) was an American chemist and physicist known for being one of the four co-inventors of the diamond anvil cell at the National Bureau of Standards in 1957, with Alvin Van Valkenburg, Ellis Lippincott and Elmer Bunting.
A hardy has a square shank, which prevents it from rotating when placed in the anvil's hardy hole. [2] The term "hardy", used alone, refers to a cutting chisel used in the square hole of the anvil. Other bottom tools are identified by function. Typical hardy tools include chisels and bending drifts. They are generally used with a matching top tool.
The operation of the diamond anvil cell relies on a simple principle: =, where p is the pressure, F the applied force, and A the area. Typical culet sizes for diamond anvils are 100–250 micrometres (μm), such that a very high pressure is achieved by applying a moderate force on a sample with a small area, rather than applying a large force on a large area.
Single-horn anvil A blacksmith working iron with a hammer and anvil A blacksmith working with a sledgehammer, assistant (striker) and Lokomo anvil in Finland. An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked").
Cleanroom furniture is designed to produce a minimum of particles and is easy to clean. A cleanroom is as much a process and a meticulous culture to maintain, as it is a space as such. Personnel contamination of cleanrooms
Twill fabrics have no "up" and "down" as they are woven. Sheer fabrics are seldom made with a twill weave. Because a twill surface already has interesting texture and design, printed twills (where a design is printed on the cloth) are much less common than printed plain weaves. When twills are printed, this is typically done on lightweight fabrics.
Anvil Studio consists of a free core program with optional add-ons. The free version is a fully functional MIDI editor/sequencer which loads and saves standard MIDI-formatted files, and allows individual tracks to be edited with a: Staff editor, Piano Roll editor, Percussion editor, TAB editor, or; MIDI event list editor.

The Archard equation is a simple model used to describe sliding wear and is based on the theory of asperity contact. [1]= where: Q is the total volume of wear debris produced K is the wear coefficient
