Flat band potential. In semiconductor physics, the flat band potential of a semiconductor defines the potential at which there is no depletion layer at the junction between a semiconductor and an electrolyte [1] or p-n-junction. This is a consequence of the condition that the redox Fermi level of the electrolyte must be equal to the Fermi level ...
An Axios/Ipsos poll found that 1 in 5 Americans don’t think they’ll ever retire — and a whopping 70% of that cohort say it’s because they simply can’t (or won’t be able to) afford it.
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, [1] is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine , each pair of opposed pistons moves inwards and outwards at the same time.
A flat-eight engine, also called a horizontally-opposed eight, is an eight-cylinder piston engine with two banks of four inline cylinders, one on each side of a central crankshaft, 180° apart. In a flat-eight engine, the connecting rods for corresponding pistons from the left and right banks may share a crankshaft journal.

Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. It plays an important role in the science and technology needed ...
This variation is called vignetting, and can be corrected by selectively brightening the perimeter of the image. Flat-field correction ( FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital ...
Flat-plane cranks are used in V-configuration engines, generally with eight cylinders. [1] Cadillac introduced a V8 flat-plane crank engine in 1923. [2] [3] Computer generated image showing the major internal moving parts of a DOHC inline-four engine, including the flat-plane crankshaft. Inline-four cylinder engines almost all use flat-plane ...
