Initial pressure of the shock front launched by a streamer discharge in water

open access: yesAIP Advances, 2021
A streamer discharge in water launches a chain of isolated shock fronts as the streamer filament propagates through the water. The initial pressure of the shock front is a good estimation of the initial pressure of the streamer filament.

Deterministic creation, pinning, and manipulation of quantized vortices in a Bose-Einstein condensate [PDF]

open access: yes, 2015
We experimentally and numerically demonstrate deterministic creation and manipulation of a pair of oppositely charged singly quantized vortices in a highly oblate Bose-Einstein condensate (BEC).

Temperature and energy effects on secondary electron emission from SiC ceramics induced by Xe17+ ions

open access: yesScientific Reports, 2017
Secondary electron emission yield from the surface of SiC ceramics induced by Xe17+ ions has been measured as a function of target temperature and incident energy. In the temperature range of 463–659 K, the total yield gradually decreases with increasing

New fine structure of red luminescence in ZnO observed under exciton resonance excitation

open access: yesAIP Advances, 2019
A new fine structure of red luminescence (RL) was observed in unintentionally doped ZnO at low temperature. The new RL was demonstrated to be different from the one assigned to Fe3+ center by Heitz et al and visible only under the excitation of light ...

Semiconductor laser beam bending

open access: yesTURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2015
This study is about a single-component cylindrical structured lens with a gradient curve that was used for bending laser beams. It operates under atmospheric conditions and bends the laser beam independently of temperature, pressure, polarity, polarization, magnetic field, electric field, radioactivity, and gravity. A single-piece cylindrical lens that

Interaction Mechanisms of Insensitive Explosive FOX-7 and Graphene Oxides from Ab Initio Calculations

open access: yesNanomaterials, 2019
Energetic material−graphene oxide (EM−GO) composites exhibit excellent thermal stability and insensitivity to mechanical stimuli. The interfacial interactions play an important role in affecting the structural and electrical properties of EM&#

Effective magnetic fields in degenerate atomic gases induced by light beams with orbital angular momenta [PDF]

open access: yes, 2005
We investigate the influence of two resonant laser beams on the mechanical properties of degenerate atomic gases. The control and probe beams of light are considered to have Orbital Angular Momenta (OAM) and act on the three-level atoms in the ...

Multi-scale-phases coherent precipitation improve the comprehensive performance of heat-resistant Cu alloys

open access: yesJournal of Materials Research and Technology, 2023
High-temperature destabilization of the strengthening phase and the generation of discontinuous precipitation at grain boundaries are mutual problem in current high-temperature alloys, especially in the novel Cu-based high-temperature alloys.
