This review paper discusses nonthermal plasma surface treatment researches and atmospheric pressure plasma hybrid treatment technology as the only effective method for achieving high-strength adhesion of fluoroplastic (Teflon), which is otherwise extremely difficult to bond using conventional plasma treatments. Although surface modification techniques such as corona discharge treatment and standard plasma treatments exist, they are generally ineffective for fluoroplastics. This paper first explains the electrode system used in the plasma treatment and the principle of hydrophilization. It then introduces atmospheric pressure plasma graft polymerization treatment developed by the authors. This review also explores its applications in improving the adhesion of fluoroplastics for high-frequency cables, automotive hose components, and medical devices, presenting production methods, adhesion performance test results, and characterization measurements.

This review article aims to describe and compare widely used numerical models for the computer simulation of key electrohydrodynamic processes occurring in electrostatic coalescers, as well as to present the main results obtained using these models. Both pairwise droplet interaction models and multi-droplet models are considered. The former are based on tracking the movement of the interfacial boundary and employ approaches such as the phase-field, conservative level-set, coupled level-set and volume of fluid, arbitrary Lagrangian–Eulerian, isoAdvector, and boundary element (or integral) methods. The latter rely on a macroscopic description of emulsion evolution via the population balance model or by solving the equations of motion for a collection of droplets. In addition, the review includes models based on the molecular dynamics method. For each model, its capabilities, advantages, disadvantages, and limitations are described, along with the possible types of results obtained and corresponding examples.
The results obtained address issues such as the threshold transition from coalescence to non-coalescence in droplet-droplet and droplet-layer systems, partial coalescence and the regime map of non-coalescence, as well as the interrelation of results derived from different types of models.

This review examines the chemical reactions induced primarily by streamer discharges in atmospheric air, focusing on their physical parameters, radical formation, and modeling approaches. Although some references to low-pressure discharges are included for fundamental comparisons, the central emphasis remains on near-atmospheric conditions. Key physical parameters such as electric field strength, streamer propagation velocity and secondary streamer characteristics play a critical role in the design of the chemical pathways. Different modelling approaches, in particular those coupling discharge dynamics with chemical reaction simulations, are analyzed to highlight their advantages and limitations. Recent advances in computational techniques and experimental diagnostics have provided deeper insights into the primary and secondary reactions that occur in streamer discharges. The effects of gas composition, humidity, voltage waveforms and interfaces on reaction mechanisms are also discussed. Emerging research trends such as plasma-liquid interactions, multi-scale modelling and the application of artificial intelligence to discharge simulations are also explored. By systematically analyzing the underlying chemical kinetics, this work aims to improve the understanding of streamer-induced plasma chemistry and its potential applications.

Charge neutralisation using corona discharge is a technology that empirically appears to work well. However, without a proper understanding of the physics of charge neutralisation, it is impossible to properly solve problems when they occur. Unfortunately, some corona ionisers make us question whether they can effectively eliminate static charge because the ionisers themselves can cause problems. Ionisers can generate an external electric field that causes induction or polarisation in an object being neutralised, potentially leading to false overcharging. This review discusses in theory how to achieve zero coulomb and zero volt charge neutralisation, what the problems are that prevent charge neutralisation, how the problems can be solved, and what test method can be used to evaluate the accurate performance of ionisers, with a view to future improvements in ioniser technology.

Nanosecond-pulse Surface Dielectric Barrier Discharge (ns-SDBD) plasma actuators are promising tools for active flow control (AFC) in high-speed, high-Reynolds-number flows via rapid gas heating and shock wave generation in the discharge, distinct from other momentum injection-based AFC methods. This paper reviews recent advancements in ns-SDBD actuators, focusing on their electrical characteristics, pressure-dependent performance, and mechanisms. Firstly, electrical characterization reveals consistent discharge mechanisms, marked by dual-peak current waveforms, with performance influenced by pulse parameters and material properties. Secondly, as pressure increases, ns-SDBD actuators exhibit significant rises in breakdown voltage accompanied by transitions from diffuse-like to filamentary discharge modes. Finally, theoretical frameworks link discharge characteristics to surface charge accumulation and fast gas heating to nitrogen-oxygen quenching. Future challenges include performance and mechanisms of mode transitions under high repetition frequencies and high pressures, detailed physical models supported by advanced diagnostics, and interdisciplinary collaboration to enhance ns-SDBD applications in aerospace and energy systems.

Flow electrification phenomenon is particularly complex as it involves materials, physics, chemistry, and fluid mechanics. It originates from the electric double layer (EDL) present at each solid/liquid interface, which results in a polarization of the interface. This physics equilibrium is determined by the nature of the materials and their physico-chemical properties. It is disrupted by the liquid flow toward a new equilibrium, described by the flow electrification phenomenon. Studied within the research framework in electrochemistry, colloid chemistry, and electrical engineering, EDL remains poorly understood. It relies on models whose viability has yet to be confirmed, as well as on often indirect experimental approaches. Zeta-metry and the flow electrification measurements constitute the main methods of study.
The evaluation and control of electrostatic hazard in an industrial and applied context can be achieved either by acting on the genesis of charge generation at interfaces or by addressing the various parameters governing the phenomenon of electrification through flow. Thus, after a description of the EDL, the phenomenon of electrification through flow will be analyzed in detail for both laminar and turbulent regimes. Particular attention will be given to studying this phenomenon in the context of electrostatic hazard in power transformers. Then, a new theoretical analysis of the flow electrification phenomenon under turbulent flows is described. Finally, an overview of new experimental approaches for analyzing the EDL will be presented.

Over the past two decades, nonthermal plasma has emerged as a promising tool for various medical applications, including wound healing, blood coagulation, decontamination, and cancer therapy. This review provides a comprehensive analysis of advancements in the field, detailing both fundamental mechanisms and recent technological developments. The medical efficacy of nonthermal plasma is primarily attributed to its physical effects, such as electric fields and ultraviolet radiation, as well as its chemical effects, driven by the production of reactive oxygen and nitrogen species (RONS). These reactive species play a critical role in inducing apoptosis and oxidative stress, thereby affecting cellular viability. Additionally, nonthermal plasma is gaining attention as a novel drug delivery system, offering targeted therapeutic potential for various diseases. However, while RONS are effective in removing harmful cells, their broader applicability to neurological and other non-cancerous diseases remains uncertain. This review explores the feasibility of plasma-based drug delivery as a controlled mechanism for therapeutic applications beyond oncology. By examining the latest innovations and challenges in plasma medicine, we aim to highlight its potential for expanding treatment modalities and addressing unmet clinical needs.
