Applications of Solid-State Nuclear Magnetic Resonance Spectroscopy in Methanol-to-Olefins Reaction

Chinese Journal of Magnetic Resonance, 2021
Methanol-to-olefins (MTO) is a prevalent industrial process for producing light olefins from the non-petroleum route. Molecular sieves are core catalysts for MTO owing to their unique pore structure and tunable acidity.

Solid-state NMR Investigation of the Host-guest Interactions in Gas Adsorption and Chemical Separation Using MOFs as Adsorbents

Chinese Journal of Magnetic Resonance, 2023
Due to its sensitivity to the local geometries and chemical environments, solid-state nuclear magnetic resonance (NMR) is widely applied to investigate the host-guest interactions between metal-organic frameworks (MOFs) and guest molecules in the studies

Nuclear spin cooling using Overhauser field selective coherent population trapping [PDF]

, 2010
Hyperfine interactions with a nuclear spin environment fundamentally limit the coherence properties of confined electron spins in the solid-state. Here, we show that a quantum interference effect in optical absorption from two electronic spin states of a

Recent Advances in Solid-State Nuclear Magnetic Resonance Spectroscopy [PDF]

Annual Review of Analytical Chemistry, 2018
The sensitivity of nuclear magnetic resonance (NMR) spectroscopy to the local atomic-scale environment offers great potential for the characterization of a diverse range of solid materials. Despite offering more information than its solution-state counterpart, solid-state NMR has not yet achieved a similar level of recognition, owing to the anisotropic

Solid-State Nuclear Spin Quantum Computer Based on Magnetic Resonance Force Microscopy [PDF]

, 1999
We propose a nuclear spin quantum computer based on magnetic resonance force microscopy (MRFM). It is shown that an MRFM single-electron spin measurement provides three essential requirements for quantum computation in solids: (a) preparation of the ...

An all silicon quantum computer [PDF]

, 2001
A solid-state implementation of a quantum computer composed entirely of silicon is proposed. Qubits are Si-29 nuclear spins arranged as chains in a Si-28 (spin-0) matrix with Larmor frequencies separated by a large magnetic field gradient.
