Brad Friedel
Bradley Howard Friedel (born May 18, 1971) is an American professional soccer coach and former player who played as a goalkeeper. Friedel played 84 games for the United States national team between 1992 and 2005, and represented his country at three FIFA World Cup tournaments. He is the current holder of the Premier League record for most consecutive appearances with 310, a feat he achieved during spells at Blackburn Rovers, Aston Villa and Tottenham Hotspur. Until he was left out of the Tottenham team on October 7, 2012, the last Premier League games Friedel missed were Blackburn's final two fixtures of the 2003–04 season against Tottenham and Birmingham City, on May 10 and 15, 2004, respectively. Friedel is also officially Aston Villa's oldest-ever player, a record he set on February 1, 2011, by playing in the club's Premier League fixture away at Manchester United.

Friedel Oscillations
In solid-state physics, Friedel oscillations, named after French physicist Jacques Friedel, arise from localized perturbations in a metallic or semiconductor system caused by a defect in the Fermi gas or Fermi liquid. Friedel oscillations are a quantum mechanical analog to electric charge screening of charged species in a pool of ions. Whereas electrical charge screening utilizes a point entity treatment to describe the make-up of the ion pool, Friedel oscillations describing fermions in a Fermi fluid or Fermi gas require a quasi-particle or a scattering treatment. Such oscillations depict a characteristic exponential decay in the fermionic density near the perturbation followed by an ongoing sinusoidal decay resembling sinc function. In 2020, magnetic Friedel oscillations were observed on a metal surface. One-dimensional electron gas As a simple model, consider one-dimensional electron gas in a half-space x > 0. The electrons do not penetrate into the half-space x \leq 0, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Layered Double Hydroxides
Layered double hydroxides (LDH) are a class of ionic solids characterized by a layered structure with the generic layer sequence cB Z AcBsub>''n'', where c represents positively charged layers of metal cations, A and B are layers of hydroxide () anions, and Z are interlayers filled by various anions (ensuring the electroneutrality of the system) and neutral molecules such as water. Lateral offsets between the layers may result in longer repeating periods. The intercalated anions (Z) are weakly electrostatically bound, often exchangeable; their intercalation properties have scientific interest and industrial applications. LDHs occur in nature as minerals, as byproducts of the metabolism of certain bacteria, and also unintentionally in man-made contexts (e.g., archaeological sites), such as the products of corrosion of metallic artefacts. Structure and formulas LDHs can be seen as derived from hydroxides of divalent cations (d) with the brucite (Mg(OH)2) layer structure dB ...

Friedel's Salt
Friedel's salt is an anion exchanger mineral belonging to the family of the layered double hydroxides (LDHs). It has affinity for anions as chloride and iodide and is capable of retaining them to a certain extent in its crystallographical structure. Composition Friedel's salt is a layered double hydroxide (LDH) of general formula: : or more explicitly for a positively-charged LDH mineral: : or by directly incorporating water molecules into the Ca,Al hydroxide layer: : where chloride and hydroxide anions occupy the interlayer to compensate the excess of positive charges. In the cement chemist notation (CCN), considering that : and doubling all the stoichiometry, it could also be written in CCN as follows: : A simplified chemical composition with only Cl– in the interlayer, and without OH–, as: : can be also written in cement chemist notation as: : Friedel's salt is formed in cements initially rich in Tricalcium aluminate, tri-calcium aluminate (C3A).

Friedel's Law
Friedel's law, named after Georges Friedel, is a property of Fourier transforms of real functions. Given a real function f(x), its Fourier transform :F(k)=\int^_f(x)e^dx has the following properties. *F(k)=F^*(-k) \, where F^* is the complex conjugate of F. Centrosymmetric points (k,-k) are called Friedel's pairs. The squared amplitude (, F, ^2) is centrosymmetric: * , F(k), ^2=, F(-k), ^2 \, The phase \phi of F is antisymmetric: * \phi(k) = -\phi(-k) \,. Friedel's law is used in X-ray diffraction, crystallography Crystallography is the branch of science devoted to the study of molecular and crystalline structure and properties. The word ''crystallography'' is derived from the Ancient Greek word (; "clear ice, rock-crystal"), and (; "to write"). In J ... and scattering from real potentials within the Born approximation.

Joshua Friedel
Joshua E. Friedel (born December 3, 1986) is an American chess player with the FIDE title of Grandmaster. He was the U.S. Open Champion in 2013. He has had notable wins against GMs Hikaru Nakamura, Boris Gulko, Ben Finegold, Timur Gareyev, and Gregory Serper. Early life Friedel was born and raised in Goffstown, New Hampshire. He learned to play chess in 1990, at age 3. Three years later, in 1993, at age 6, he became a student under NM Hal Terrie and entered his first tournament that same year.
