Melting and Re-Freezing Leads to Irreversible Changes in the Morphology and Molecular-Level Dynamics of Pfizer-BioNTech COVID-19 Vaccine

Medicina, 2021
Background and Objectives: As an mRNA-based vaccine, the Pfizer-BioNTech COVID-19 vaccine has stringent cold storage requirements to preserve functionality of the mRNA active ingredient.

Molecular dynamics decomposition of temperature-dependent elastic neutron scattering by a protein solution [PDF]

, 2003
Molecular dynamics simulations are performed of bovine pancreatic trypsin inhibitor in a cryosolution over a range of temperatures from 80 to 300 K and the origins identified of elastic dynamic neutron scattering from the solution. The elastic scattering

Proton dynamics in phosphotungstic acid impregnated mesoporous silica proton exchange membrane materials

Green Energy & Environment, 2017
Phosphotungstic acid is an excellent proton conductor that can be incorporated into porous supports, and nanocomposite proton exchange membrane materials made from mesoporous silica impregnated with phosphotungstic acid have been suggested for use in ...

Temperature and timescale dependence of protein dynamics in methanol : water mixtures [PDF]

, 2005
Experimental and computer simulation studies have suggested the presence of a transition in the dynamics of hydrated proteins at around 180–220 K. This transition is manifested by nonlinear behaviour in the temperature dependence of the average atomic ...

Dynamics studied by Quasielastic Neutron Scattering (QENS) [PDF]

Adsorption, 2021
AbstractQuasielastic neutron scattering (QENS) allows measurement of the molecular displacements in time and space, from pico- to tens of nanoseconds and from Ångstroms to nanometers, respectively. The method probes dynamics from fast vibrational modes down to slow diffusive motion.

High Ionic Conduction in Rb- and Cs-Mixed Cation Amide for Energy Storage. [PDF]

Small
A mixed cation‐amide solid solution, Rb0.5Cs0.5NH2, based on the interaction between RbNH2‐ and CsNH2, has been developed. The Rb⁺/Cs⁺ cationic substitution leads to structural stabilization, resulting in high ionic conductivity in the Rb0.5Cs0.5NH2 compared to the single compounds.

Enzyme dynamics and activity: timescale dependence of dynamical transitions in glutamate dehydrogenase solution [PDF]

, 1999
We have examined the temperature dependence of motions in a cryosolution of the enzyme glutamate dehydrogenase (GDH) and compared these with activity.

Study of the water dynamics near hydrophilic, nanostructured CuO surfaces by quasielastic and inelastic neutron scattering

AIP Advances, 2022
We have used quasielastic and inelastic neutron scattering to investigate the structure, dynamics, and phase transitions of water interacting with superhydrophilic CuO surfaces that not only possess a strong affinity for water but also a “grass-like ...
