Study of Atmospheric Plasma-Based Mass Separation System for High-Level Radioactive Waste Treatment

open access: yesPlasma, 2023
Solid spent nuclear fuel from nuclear power plants contains 3.4% fission products (80–160 amu), contributing to a radioactivity level of over 99.8%. On the other hand, liquid high-level radioactive waste (HLRW) from spent fuel reprocessing is composed of

A co-condensation model for in-flight synthesis of metal-carbide nanoparticles in thermal plasma jet [PDF]

open access: yes, 2008
We present a theoretical analysis of the formation, growth, and transport of two-component nanoparticles in thermal plasma jet. The approach of the aerosol science and the idea of multicomponent co-condensation are employed for the analysis.

Plasma Technology–Preparing for the Electrified Future

open access: yesFrontiers in Mechanical Engineering, 2022
We refer to the fourth state of matter as plasma, indicating ionized, electrically quasi-neutral gas. Electrical discharge in a gas medium is a normal and easy way of turning the gas into plasma in a moderate pressure condition. The electron temperature,

Synthesis and characterization of spherical amorphous alumo-silicate nanoparticles using RF thermal plasma method [PDF]

open access: yes, 2013
The RF thermal plasma synthesis route was used for the preparation of alumo-silicate spherical particles. Homogeneous solid mixtures of raw materials (Al2O3, SiO2 and KOH) were used as precursors.

Thermal Plasma Synthesis of Crystalline Gallium Nitride Nanopowder from Gallium Nitrate Hydrate and Melamine

open access: yesNanomaterials, 2016
Gallium nitride (GaN) nanopowder used as a blue fluorescent material was synthesized by using a direct current (DC) non-transferred arc plasma. Gallium nitrate hydrate (Ga(NO3)3∙xH2O) was used as a raw material and NH3 gas was used as a nitridation ...

Effect of Low-Temperature Plasma Jet on Thermal Stability and Physical Structure of Type I Collagen [PDF]

open access: yes, 2012
This work is devoted to the characterization of type I collagen treated by a low-temperature plasma jet generated in ambient air to determine whether the resulting fibrous material is structurally preserved or reinforced.

Heat Transfer Through Plasma-Sprayed Thermal Barrier Coatings in Gas Turbines: A Review of Recent Work [PDF]

open access: yes, 2009
A review is presented of how heat transfer takes place in plasma-sprayed (zirconia-based) thermal barrier coatings (TBCs) during operation of gas turbines. These characteristics of TBCs are naturally of central importance to their function. Current state-

Non-thermal plasma causes Pseudomonas aeruginosa biofilm release to planktonic form and inhibits production of Las-B elastase, protease and pyocyanin

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
The increasing risk of antibiotic failure in the treatment of Pseudomonas aeruginosa infections is largely related to the production of a wide range of virulence factors.
