High-Sensitivity H₂ and CH₄ SAW Sensors with Carbon Nanowalls and Improvement in Their Performance after Plasma Treatment

Chemosensors, 2023
We have developed surface acoustic wave (SAW) sensors with high sensitivity and a reversible response at room temperature (RT). The sensitive area of the sensor was prepared from vertically aligned graphene sheets, like carbon nanowalls (CNWs), which ...

Development of low-coherence high-power laser drivers for inertial confinement fusion

Matter and Radiation at Extremes, 2020
The use of low-coherence light is expected to be one of the effective ways to suppress or even eliminate the laser–plasma instabilities that arise in attempts to achieve inertial confinement fusion.

An all-sputtered photovoltaic ultraviolet photodetector based on co-doped CuCrO2 and Al-doped ZnO heterojunction

Scientific Reports, 2021
We propose and fabricate a heterojunction between Al-doped ZnO and (Mg, N)-doped CuCrO2 thin films using the sputtering deposition method. These materials possess wide bandgap that makes them transparent in the visible light but excellent UV-absorbers ...

Design and fabrication of multi-layers antireflection coating consisting of MgF2 and SiO2 [PDF]

Progress in Physics of Applied Materials, 2023
In this research, MgF2 and SiO2 thin films were prepared by the magnetron sputtering method on glass and ITO substrates. The crystal structure, morphology, and antireflection performance of the coatings were characterized using X-ray diffraction (XRD ...

Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]

, 2000
We study the energetics of wake excitation during the laser-plasma interaction in application to laser wakefield accelerators. We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping ...

The Influence of the Structural and Morphological Properties of WO₃ Thin Films Obtained by PLD on the Photoelectrochemical Water-Splitting Reaction Efficiency

Nanomaterials, 2021
Due to its physical and chemical properties, the n-type tungsten oxide (WO3) semiconductor is a suitable photoanode for water decomposition reaction. The responses of the photoelectrochemical PEC water-splitting properties as an effect of structural and ...

Measurement of the sound velocity of shock compressed water

Scientific Reports, 2021
The sound velocities of water in the Hugoniot states are investigated by laser shock compression of precompressed water in a diamond anvil cell. The obtained sound velocities in the off-Hugoniot region of liquid water at precompressed conditions are used
