Dynamics of proteins with different molecular structures under solution condition

open access: yesScientific Reports, 2020
Incoherent quasielastic neutron scattering (iQENS) is a fascinating technique for investigating the internal dynamics of protein. However, low flux of neutron beam, low signal to noise ratio of QENS spectrometers and unavailability of well-established ...

Hydride Migration within RhH2Ag19 Superatom: A Combined Neutron Diffraction and DFT Analysis

open access: yesSmall, Volume 21, Issue 18, May 5, 2025.
By modifying the crystallization conditions, the migration pathway of interstitial hydrides is visualized for the first time and analyzed through neutron diffraction experiments combined with DFT calculations. The computational results reveal an approximate migration energy barrier of 4.2 kcal mol−1, providing a reasonable explanation for the ...

Candidate quantum spin ice in the pyrochlore Pr$_2$Hf$_2$O$_7$ [PDF]

open access: yes, 2016
We report the low temperature magnetic properties of the pyrochlore Pr$_2$Hf$_2$O$_7$. Polycrystalline and single-crystal samples are investigated using time-of-flight neutron spectroscopy and macroscopic measurements, respectively.

How sensitive are protein hydration shells to electrolyte concentration and protein composition?

open access: yesProtein Science, Volume 34, Issue 1, January 2025.
Abstract Proteins of obligate halophilic organisms have an unusually high number of acidic amino acids, thought to enable them to function in multimolar KCl environments. Clarifying the molecular scale mechanisms by which this occurs is relevant for biotechnology, to enable enzymatic synthesis of economically important small molecules in salty ...

Understanding the Structure and Dynamics of Complex Biomembrane Interactions by Neutron Scattering Techniques.

open access: yesLangmuir, 2020
The membrane is one of the key structural materials of biology at the cellular level. Composed predominantly of a bilayer of lipids with embedded and bound proteins, it defines the boundaries of the cell and many organelles essential to life and ...

Underlying Roles of Polyol Additives in Promoting CO2 Capture in PEI/Silica Adsorbents

open access: yesChemSusChem, Volume 17, Issue 22, November 25, 2024.
Poly(ethylenimine) (PEI) mixed with short‐chain poly(ethylene glycol) (PEG) additives and co‐impregnated to mesoporous SBA‐15 silica demonstrate enhanced CO2 capacities and uptake rates. Neutron scattering, solid‐state NMR, and molecular dynamics simulations reveal that favorable PEI distribution is crucial.

Momentum-space structure of quasielastic spin fluctuations in Ce3Pd20Si6

open access: yes, 2014
Among heavy-fermion metals, Ce$_3$Pd$_{20}$Si$_6$ is one of the heaviest-electron systems known to date. Here we used high-resolution neutron spectroscopy to observe low-energy magnetic scattering from a single crystal of this compound in the ...

Neutron scattering study of ferroelectric Sn2P2S6 under pressure [PDF]

open access: yes, 2012
Ferroelectric phase transition in the semiconductor Sn2P2S6 single crystal has been studied by means of neutron scattering in the pressure-temperature range adjacent to the anticipated tricritical Lifshitz point (p=0.18GPa, T=296K).

CO2 Uptake and Stability Enhancement in Vinyltrimethoxysilane‐Treated SBA‐15 Solid Amine‐Based Sorbents

open access: yesSmall, Volume 20, Issue 46, November 14, 2024.
A new surface treatment using vinyltrimethoxysilane on poly(ethyleneimine) (PEI)‐loaded B‐doped mesoporous silica is reported, which increases the activity of nitrogen sorption sites for CO2 capture under direct air capture and point‐source capture conditions.
