The roles of charge exchange and dissociation in spreading Saturn's neutral clouds

, 2012
Neutrals sourced directly from Enceladus's plumes are initially confined to a dense neutral torus in Enceladus's orbit around Saturn. This neutral torus is redistributed by charge exchange, impact/photodissociation, and neutral-neutral collisions to ...

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

FEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

Acid solvation versus dissociation at “stardust conditions”: Reaction sequence matters

Science Advances, 2019
Chemistry, such as dissociation of acids, can even be triggered at ultracold “stardust conditions” in the absence of radiation. Chemical reactions at ultralow temperatures are of fundamental importance to primordial molecular evolution as it occurs on ...

On the Dissociation Equilibrium of H2 in Very Cool, Helium-Rich White Dwarf Atmospheres

, 2005
We investigate the dissociation equilibrium of $\rm H_2$ in very cool, helium-rich white dwarf atmospheres. We present the solution of the non-ideal chemical equilibrium for the dissociation of molecular hydrogen in a medium of dense helium. We find that

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

FEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

A Full-Dimensional Model of Ozone Forming Reaction: The Absolute Value of the Recombination Rate Coefficient, Its Pressure and Temperature Dependencies [PDF]

, 2016
Rigorous calculations of scattering resonances in ozone are carried out for a broad range of rotational excitations. The accurate potential energy surface of Dawes is adopted, and a new efficient method for calculations of ro–vibrational energies, wave ...

Can Density Matrix Embedding Theory with the Complete Activate Space Self-Consistent Field Solver Describe Single and Double Bond Breaking in Molecular Systems?

, 2017
Density matrix embedding theory (DMET) [Phys. Rev. Lett.2012, 109, 186404] has been demonstrated as an efficient wave-function-based embedding method to treat extended systems.

NMR screening of low molecular weight inhibitors targeting the papain‐like protease (PLPro) of SARS‐CoV‐2

FEBS Open Bio, EarlyView.
Papain‐like protease from SARS‐CoV‐2 plays an important role in the cleavage of the viral polyproteins and in the suppression of the host's immune response. Here, we present the results of an NMR screening study. We identified 86 binding compounds, of which five candidates were chosen for in‐depth analysis.
