NMR evidence for static local nematicity and its cooperative interplay with low-energy magnetic fluctuations in FeSe under pressure [PDF]

open access: yes, 2017
We present $^{77}$Se-NMR measurements on single-crystalline FeSe under pressures up to 2 GPa. Based on the observation of the splitting and broadening of the NMR spectrum due to structural twin domains, we discovered that static, local nematic ordering ...

Investigation of Physico Chemical, Mechanical and Thermal Properties of the Albizia Lebbeck Bark Fibers

open access: yesJournal of Natural Fibers, 2021
The production of materials using synthetic fibers is a strong contributor to carbon emissions and waste. Because of growing environmental consciousness, natural fibers act as a substitute for synthetic fibers due to their renewable, eco-friendly and bio-

An optical NMR spectrometer for Larmor-beat detection and high-resolution POWER NMR [PDF]

open access: yes, 2008
Optical nuclear magnetic resonance (ONMR) is a powerful probe of electronic properties in III-V semiconductors. Larmor-beat detection (LBD) is a sensitivity optimized, time-domain NMR version of optical detection based on the Hanle effect.

Classical model for bulk-ensemble NMR quantum computation [PDF]

open access: yes, 1999
We present a classical model for bulk-ensemble NMR quantum computation: the quantum state of the NMR sample is described by a probability distribution over the orientations of classical tops, and quantum gates are described by classical transition ...

Conformation and dynamics of soluble repetitive domain elucidates the initial β-sheet formation of spider silk

open access: yesNature Communications, 2018
β-sheet structure underlies the mechanical properties of spider silk but the mechanism to form β-sheet from soluble silk protein during transition into insoluble fibers has not been elucidated.

A new structural arrangement in proteins involving lysine NH3 + group and carbonyl

open access: yesScientific Reports, 2017
Screening of the Protein Data Bank led to identification of a recurring structural motif where lysine NH3 + group interacts with backbone carbonyl. This interaction is characterized by linear atom arrangement, with carbonyl O atom positioned on the three-
