Spectral and amplitude-time characteristics of crystals excited by a runaway electron beam

open access: yesMatter and Radiation at Extremes, 2019
The generation of runaway electrons (REs) is a significant problem in tokamak installations, causing energy loss, and melting and vaporization of the walls of the vacuum chamber.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

On gravitational wave-Cherenkov radiation from photons when passing through diffused dark matters [PDF]

open access: yes, 2017
Analogy to Cherenkov radiation, when a particle moves faster than the propagation velocity of gravitational wave in matter ($v>c_{\rm{g}}$), we expect gravitational wave-Cherenkov radiation (GWCR).

Recent Advances and Constructing Strategies of Chemiluminescence‐ and Bioluminescence‐Based Photodynamic Therapy

open access: yesChemPhotoChem, Volume 9, Issue 10, October 14, 2025.
Photodynamic therapy (PDT) is a noninvasive therapy for cancer and many other diseases. A PDT system includes three key components: a light source, photosensitizers (PSs), and oxygen. Internal light sources, such as chemiluminescence (CL) and bioluminescence (BL), trigger PDT without external irradiation, allowing for more flexibility.

A Study on the Lateral Distribution of Cherenkov Radiation of Extensive Air Showers at High Observation Levels [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics
By using CORSIKA code, for simulation of extensive air showers for observation levels at different altitudes, the variation of the lateral distribution of Cherenkov radiation of showers with altitude is studied.
