Since the last decade, research on plasma catalysis has attracted keen attention as an emerging type of low-carbon technology. An advantage of plasma is to facilitate non-equilibrium reaction fields on a large scale that is inaccessible by conventional thermal approaches. Stable molecules such as CO2 and CH4 are activated by electrical energy, paving the frontier of low-temperature chemistry that departs from energy-intensive heat-dependent systems. Moreover, the Power-to-Chemical concept would gain momentum with the plasma technologies that are driven by renewable energy. Currently, research is accelerating with application initiatives, but at the same time, the importance of scientific understanding of plasma catalytic reactions is being recognized more than ever. This review article overviews various plasma technologies in the "plasma alone" and "plasma-catalyst combination" context. Plasma-catalyst combination technology, known as Plasma Catalysis, is discussed further to dry methane reforming (CH4+CO2=2CO+2H2) and to reverse water gas shift reaction (CO2+H2=CO+H2O) for the mechanistic insight.

A detailed review of the scientific literature was undertaken to examine the most recent developments in plasma processing in the field of medicine. The first part of the review includes a detailed breakdown of the different types of coatings that can be applied onto medical devices using plasma, with a specific focus on antimicrobial surfaces. The developments in plasma-deposited biocompatibles, drug delivery and adhesive coatings in 2023 are described, and specific applications in additive manufacturing are highlighted. The use of plasma and plasma-activated liquids as standalone therapeutics continues to evolve, and pertinent advances in this field are described. In addition, the combination of plasma medicine with conventional pharmaceutical interventions is reviewed, and key emerging trends are highlighted, including the use of plasma to enhance drug delivery directly into tissue. The potential synergies between plasma medicine and chemotherapeutics for oncology and infection treatment are a growing area, and recent advancements are noted. Finally, the use of plasma to control excess antibiotics and to intentionally degrade such materials in waste streams is described.

Packed bed dielectric barrier discharges exhibit an improved energy efficiency and selectivity in nonthermal plasma based gas conversion. They enable the direct interaction between plasma and catalyst. In this contribution a compact coaxial DBD reactor enabling the end-on imaging of the discharge with and without packed beds is constructed and studied. The discharge morphology is correlated with electrical measurements such as V-Q plots. The studies are performed for different packed bed materials, binary gas compositions of argon and carbon dioxide, voltage amplitudes, average powers, and pressures. The analysis points outs the role of parasitic capacitances and parasitic discharges as often overlooked aspects. The introduction of the packed bed material into the coaxial barrier discharge arrangement increases the total capacitance, but the barrier of the outer glass tube mostly determines the maximum effective dielectric capacitance. The choice of the packed bed material determines the voltage threshold and the average discharge power. The investigations leads to a revision of the equivalent circuit for packed bed barrier discharge reactors, which also accounts the properties of different filling materials.
