Plasma Science and Technology - Progress in Physical States and Chemical Reactions

Abstract

Non-thermal plasma technology is one of those techniques that suffer relatively little from diffusion limits, slow kinetics, and complex geometries compared to more traditional liquid-based chemical surface modification techniques. Combined with a lack of solvents, preservation of the bulk properties, and fast treatment times; it is a well-liked technique for the treatment of materials for biomedical applications. In this book chapter, a review will be given on what the scientific community determined to be essential to obtain appropriate scaffolds for tissue engineering and how plasma scientists have used non-thermal plasma technology to accomplish this. A distinction will be made depending on the scaffold fabrication technique, as each technique has its own set of specific problems that need to be tackled. Fabrication techniques will include traditional fabrication methods, rapid prototyping, and electrospinning. As for the different plasma techniques, both plasma activation and grafting/polymerization will be included in the review and linked to the in-vitro/in-vivo response to these treatments. The literature review itself is preceded by a more general overview on cell communication, giving useful insights on how surface modification strategies should be developed.

Characterization and comparative evaluation of two atmospheric plasma sources for water treatment

“…In a 2016 review, [8] Vanraes et al reported on yet another recently investigated group of configurations, so called "remotely generated plasmas", in which the plasma is generated outside of the liquid phase and its radical products are bubbled into the solution. The principle is similar to ozonation, with the important difference, however, that the bubbled gas also contains other reactive species, such as H 2 O 2 and OH radicals.…”

Quantitative absorption spectroscopy of laser-produced plasmas

“…Versatility and ease of measurement make emission spectroscopy attractive, but interpretation of the data can often be challenging. Emission measurements collect light from a specified region along the main axis of the collection optics, and collection efficiency varies with spatial location in the plasma [7,17]. Thus the collected spectrum is the convolution of many weighted spectra from the collection volume.…”
