Solid-state 900 MHz ( 21. 1 T ) NMR spectrometer at the Canadian National Ultrahigh-field NMR Facility for Solids. Solid-state NMR ( SSNMR ) spectroscopy is a kind of nuclear magnetic resonance ( NMR ) spectroscopy, characterized by the presence of anisotropic ( directionally dependent ) interactions.

Solid-state NMR spectroscopy serves as an analysis tool in organic and inorganic chemistry.

:* Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy.

Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power.

Solid-state lasers are usually pumped by flashlamps or light from another laser.

Solid-state pseudopotentials achieved their present popularity largely because of the successful fits by Walter Harrison to the nearly free electron Fermi surface of Aluminum ( 1958 ) and J. C. Phillips to the covalent energy gaps of Silicon and Germanium ( 1958 ).

Solid-state nanopores are generally made in silicon compound membranes, one of the most common being silicon nitride.

Often thought of as a hybrid between quantum dot and NMR quantum computers, the Kane computer is based on an array of individual phosphorus donor atoms embedded in a pure silicon lattice.

Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance ( NMR ), electron spin resonance ( ESR ) and resonance of quantum wave functions.

Nuclear magnetic resonance ( NMR ) is the name given to a physical resonance phenomenon involving the observation of specific quantum mechanical magnetic properties of an atomic nucleus in the presence of an applied, external magnetic field.

In 2001, Shor's algorithm was demonstrated by a group at IBM, who factored 15 into 3 × 5, using an NMR implementation of a quantum computer with 7 qubits.

A working 2-qubit NMR quantum computer used to solve Deutsch's problem was demonstrated by Jonathan A Jones and Michele Mosca at Oxford University and shortly after by Isaac L. Chuang at IBM's Almaden Research Center together with coworkers at Stanford University and MIT.

* 1999 – Samuel L. Braunstein and collaborators showed that there was no mixed state quantum entanglement in any bulk NMR experiment.

Pure state quantum entanglement is necessary for any quantum computational speedup, and thus this gave evidence that NMR computers would not yield benefit over classical computer.

This, coupled with Brauenstein's result ( see 1999 above ), called the validity of NMR quantum computation into question.

* 2004 – First working pure state NMR quantum computer ( based on parahydrogen ) demonstrated at Oxford University and University of York.

* In quantum computing, the first working 7-qubit NMR computer is demonstrated at IBM's Almaden Research Center, demonstrating Shor's algorithm.

The EFG couples with the nuclear electric quadrupole moment of quadrupolar nuclei ( those with spin quantum number greater than one-half ) to generate an effect which can be measured using several spectroscopic methods, such as nuclear magnetic resonance ( NMR ), electron paramagnetic resonance ( EPR, ESR ), nuclear quadrupole resonance ( NQR ), Mössbauer spectroscopy or perturbed angular correlation ( PAC ).

A revolutionary advance is Lucio Frydman's multiple quantum magic angle spinning ( MQMAS ) NMR in 1995 and it has become a routine method for obtaining high resolution solid-state NMR spectra of quadrupolar nuclei.

Although trained in chemistry he is better known for his work in physics, especially for his work on NMR quantum computation for which he was awarded the 2000 Marlow Medal of the Royal Society of Chemistry.

At MIT, he worked on NMR, including his work on NMR quantum computation.

Together with Amr Fahmy and Timothy Havel he developed the concept of pseudo-pure states and performed the first experimental demonstrations of NMR quantum computing.

* Nuclear magnetic resonance on molecules in solution ( liquid-state NMR ) ( qubit provided by nuclear spins within the dissolved molecule )

Nuclear magnetic resonance ( NMR ) is a technique by which external magnetic fields can be used to find resonance modes of individual electrons, thus giving information about the atomic, molecular and bond structure of their neighborhood.

This ratio of large HDL to total HDL particles varies widely and is measured only by more sophisticated lipoprotein assays using either electrophoresis ( the original method developed in the 1970s ) or newer NMR spectroscopy methods ( See also: NMR and spectroscopy ), developed in the 1990s.

In a 1971 paper in the journal Science, Dr. Raymond Damadian, an Armenian-American physician, scientist, and professor at the Downstate Medical Center State University of New York ( SUNY ), reported that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance (" NMR ").

However, NMR experiments are able to provide information from which a subset of distances between pairs of atoms can be estimated, and the final possible conformations for a protein are determined by solving a distance geometry problem.

The first atomic-resolution structures of proteins were solved by X-ray diffraction analysis in the 1960s ( Perutz and Kendrew shared the 1962 Nobel Prize in Chemistry for these discoveries ) and by NMR in the 1980s.

Distinct nuclear spin states can have their energy separated by a magnetic field, and this allows for NMR spectroscopy.

Tacticity measurements obtained by Carbon-13 NMR are typically expressed in terms of the relative abundance of various pentads within the polymer molecule, e. g. mmmm, mrrm.

The shape and structure of viruses has been studied by electron microscopy, NMR spectroscopy, and X-ray crystallography.

Much of this work is summarized in a book by Gareth Eaton and William Lipscomb, NMR Studies of Boron Hydrides and Related Compounds, one of Lipscomb's two books.

In each of these materials, the anisotropic nature of the pairing is implicated by the power-law dependence of the nuclear magnetic resonance ( NMR ) relaxation rate and specific heat capacity on temperature.

In 2008, the ADA and ACC recognized direct LDL particle measurement by NMR as superior for assessing individual risk of cardiovascular events.

Protein folding is routinely studied using NMR spectroscopy, for example by monitoring hydrogen-deuterium exchange of partially folded intermediates.

Experimentally, pK < sub > a </ sub > values can be determined by potentiometric ( pH ) titration, but for values of pK < sub > a </ sub > less than about 2 or more than about 11, spectrophotometric or NMR measurements may be required due to practical difficulties with pH measurements.

The NMR was declared by the UNESCO as a World Heritage Site in July 2005.

The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations ( PDBe, PDBj, and RCSB ).

In addition, a specific H-N ...( O )- P NMR experiment ( INEPT transfer by scalar coupling 3JH-P ~ 5 Hz ) could provide a direct information about formation of hydrogen bonds between amid protons of protein to phosphate of lipid headgroups, which is useful in studies of protein / membrane interactions.

Before birth, complex ultrasounds performed routinely during pregnancy may indicate the presence of cerebral abnormality, but this method of diagnosis should be complemented by other methods, such as genetic studies and NMR, and the examination is not recommended as part of routine ultrasound examinations, unless family medical history or other reasons for suspecting brain malformation are present.
