Photoionization Impact on the Lightning Impulse Streamer Discharge of Rapeseed Insulating Oil: An Experimental Study

open access: yesEnergies
Photoionization is a significant factor influencing the morphology and propagation characteristics of streamers in insulating oil, yet research on the impact of photoionization on streamer branching is almost nonexistent.

On Phase and Amplitude Extraction in Bichromatic Ionization: A Proposal

open access: yesPhotonics, 2023
In the paper we propose a method for characterizing VUV pulse(s) in a bichromatic ionization setup. The scheme is based on s-shell ionization by joint action of circularly polarized fundamental harmonic and linearly polarized second one. The advantage of

Multiple photoionization for the 2p subshell in the iron atom / [PDF]

open access: yes, 2022
Multiple photoionization is investigated for the 2p subshell in the iron atom. Study of the single photoionization with subsequent radiative and Auger cascade includes levels corresponding to the ground configuration. This work reveals that the quadruple

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

open access: yesBattery 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 ...

Spectral self-action of THz emission from ionizing two-color laser pulses in gases

open access: yesNew Journal of Physics, 2015
The spectrum of terahertz (THz) emission in gases via ionizing two-color femtosecond pulses is analyzed by means of a semi-analytic model and numerical simulations in 1D, 2D and 3D geometries taking into account propagation effects of both pump and THz ...

On Photoeffect in the Few-Electron Atomic Systems

open access: yesAtoms, 2022
Closed analytical formulas are derived for the differential and total cross sections of the non-relativistic photoelectric effect in the three main classes of few-electron atomic systems: (a) neutral atoms and positively charged atomic ions which contain

Constructing Biomass‐Derived Ultra‐Thin 2D Carbon Nanoweb via Confinement‐Driven Bubbling Effect for High‐Rate Zinc‐Ion Storage in Hybrid Capacitors

open access: yesCarbon Energy, EarlyView.
A confinement‐derived bubbling effect strategy is used for controllable synthesis of biomass‐derived 2D carbon nanoweb with ultra‐thin longitudinal dimensions (1.5−2.5 nm) and high surface area (2055 m2 g−1). Its ultra‐thin 2D nanoweb structure enhances rate capability and cycling stability at high charge–discharge rates and in high‐mass‐loading ...

Spectroscopic Peculiarities at Ionization of Excited 2p5(2PJf)3s[K]0,1,2 States of Ne: Cooper Minima and Autoionizing Resonances

open access: yesAtoms, 2022
An extensive study of photoionization from neon excited states was performed. The R-matrix approach was applied to calculate a photoionization cross-section from the metastable 2p5(2PJf)3s[K]0,2 and dipole-allowed 2p5(2PJf)3s[K]1 states.
