Generation mechanism of precursor electrons ahead of a hypersonic shock wave in argon

Journal of Fluid Science and Technology, 2014
The purpose of the research is to clarify the generation mechanism of precursor electrons ahead of a hypersonic shock wave in argon. The triple-probe measurements and radiation measurements are carried out using a hypersonic shock tube.

A Fully Relativistic Approach to Photon Scattering and Photoionization of Alkali Atoms

Atoms, 2021
A fully relativistic approach to calculating photoionization and photon-atom scattering cross sections for quasi one-electron atoms is presented. An extensive set of photoionization cross sections have been calculated for alkali atoms: lithium, sodium ...

Lithium Borate/Boric Acid Optimized Multifunctional Binder Facilitates Silicon Anodes With Enhanced Initial Coulombic Efficiency, Structural Strength, and Cycling Stability

Battery Energy, Volume 4, Issue 2, March 2025.
This research introduces a novel organic‐inorganic binder: sodium alginate‐lithium borate‐boric acid (Alg‐LBO‐BA), whose three‐dimensional network effectively buffers the volumetric changes of Si, maintaining overall stability. Additionally, LBO serves as a prelithiation agent, compensating for irreversible lithium consumption during SEI formation ...

Optimal Stochastic Enhancement of Photoionization [PDF]

Physical Review Letters, 2007
The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schrödinger equation. A modest amount of white noise results in an enhancement of the net ionization yield by several orders of magnitude, giving rise to a form of quantum stochastic resonance.

Photoionization of Rydberg atoms in optical lattices

New Journal of Physics, 2021
We develop a formalism for photoionization (PI) and potential energy curves (PECs) of Rydberg atoms in ponderomotive optical lattices and apply it to examples covering several regimes of the optical-lattice depth.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Dissociative Photoionization of Quinoline and Isoquinoline [PDF]

The Journal of Physical Chemistry A, 2015
Two nitrogen-containing polycyclic aromatic hydrocarbon isomers of C9H7N composition, quinoline, and isoquinoline have been studied by imaging photoelectron photoion coincidence spectroscopy at the VUV beamline of the Swiss Light Source. High resolution threshold photoelectron spectra have been recorded and are interpreted applying a Franck-Condon ...

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...
