Experimental Investigation for the Removal of Toxic Gases from Vehicle Exhaust using Non-Thermal Plasma

Journal of Engineering, 2018
In this study, the use of non-thermal plasma theory to remove toxic gases emitted from a vehicle was experimentally investigated. A non-thermal plasma reactor was constructed in the form of a cylindrical tube made of Pyrex glass. Two stainless steel rods

“STRING” TYPE OF BARRIERLESS PLASMA CHEMICAL REACTOR FOR GENERATION OZONE FROM AIR

Problems of Atomic Science and Technology, 2021
The efficiency of ozone generation for barrierless plasma chemical reactors with different cathode designs was compared. The characteristics of ozone generation for a plasma chemical reactor with a string-type cathode in comparison with the previously developed star-shaped cathode for different combinations of bias and pulsed components of voltage have

Development of Multifunctional Hierarchically Restructured Antibacterial Neural Interfacing Electrodes via Plasma‐Enhanced Atomic Layer Deposition of Zinc Oxide Thin Films

Advanced Functional Materials, EarlyView.
ABSTRACT Next‐generation implantable neural‐interfacing devices are increasingly constrained by the coupled demands of electrode miniaturization, electrochemical performance, and implantation infection risk. Femtosecond laser–based hierarchical surface restructuring (HSR) technology has emerged as a scalable, manufacturing‐compatible platform for ...

Lifetime of nitric oxide produced by surface dielectric barrier discharge in controlled atmospheres: Role of O2 content

Chemical Engineering Journal Advances
Nitric oxide (NO) is an invaluable multifunctional chemical in agri-food applications; for example, it plays a role in plant growth, development, and stress tolerance. One of the interesting implications of NO is the suppression of fruit ripening and the

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

Advanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Influence of plasma-chemical etching on the surface structure of silicon wafers for photovoltaic converters

Технологія та конструювання в електронній апаратурі, 2006
The results of plasma-chemical etching (PCE) of the surface of photovoltaic converter (PVC) wafers, pre-structured by chemical etching, are presented. PCE was carried out in a plasma-chemical reactor using a mixture of sulfur hexafluoride (SF₆) and 10 ...

Modelling of heating of plasma-chemical reactor in Comsol Multiphysics.

Journal of Physics: Conference Series, 2018
For the thermophysical calculation of the reactor, a mathematical model was developed in Comsol Multiphysics, describing physical processes in the plasma-chemical reactor at a stationary mode. To simplify the calculation at this stage, it was carried out for an air plasma torch. The model includes two processes: fluid dynamic and heat transfer ones. As

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Plug flow reactor model of the plasma chemical conversion of CO₂

Plasma Sources Science and Technology, 2019
Abstract A 1D plug flow model suitable for describing the CO2 conversion into CO in microwave plasma reactors is proposed. The model is applied together with the Antwerp data set for the CO2 reaction kinetics to calculate parameter scans for a realistic experimental set up.
