Observation of the significant reductions of electron density and electron temperature in a cascaded arc high density argon plasma with ammonia seeding comparing with nitrogen seeding by laser Thomson scattering approach

Nuclear Materials and Energy, 2022
In this work, the influences of ammonia (NH3) seeding on the electron density (ne) and electron temperature (Te) in a high-density cascaded arc argon plasma have been investigated by laser Thomson scattering. As NH3 seeding ratio increases from 0% to 2%,

Use of impurities to increase yield of seeds for food purposes

Naukovì Dopovìdì Nacìonalʹnogo Unìversitetu Bìoresursiv ì Prirodokoristuvannâ Ukraïni, 2021
The growth-stimulating activity of the drug "Humir", created on the basis of humates, polyethylene oxides, wastes of yeast production, hydrated fullerenes and other BAS is investigated. The introduction of these components in the technology of crop production requires careful study of the properties of drugs based on them in specific soil and climatic ...

Transport analysis of high radiation and high density plasmas in the ASDEX Upgrade tokamak

EPJ Web of Conferences, 2014
Future fusion reactors, foreseen in the “European road map” such as DEMO, will operate under more demanding conditions compared to present devices. They will require high divertor and core radiation by impurity seeding to reduce heat loads on divertor ...

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Gyrokinetic simulations of electrostatic microturbulence in ADITYA-U tokamak with argon impurity

Nuclear Fusion
The effect of impurity on the electrostatic microturbulence in ADITYA-U tokamak is assessed using global gyrokinetic simulations. The realistic geometry and experimental profiles of the ADITYA-U are used, before and after argon gas seeding, to perform ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
