“…Our earlier investigations of cellulose fibers by AFM showed that a 30 s long plasma treatment caused a slight, but detectable roughness increase. However, the statistical significance could not be unequivocally ascertained.…”

Quantitation of surface roughness is difficult, if subtle, but significant differences cause an uncommon variance. We used atomic force microscopy to measure the surface roughness of polyethylene terephthalate (PET) fibers before and after a 30 s plasma treatment of 300 W. Samples were measured multiple times at different locations, in four scan sizes. The surface roughness was expressed in terms of nine roughness parameters. Despite the large number of data, simple statistics was not able to detect significant differences in roughness before and after plasma treatment. A factorial analysis of variance (ANOVA) of the normalized data and a sum of ranking differences analysis using four types of data preprocessing and their factorial ANOVA confirmed that (i) the plasma treatment had roughened the PET fiber surface; (ii) the roughness increases with the scanned area in the measured range; and (iii) what the best roughness parameters are in discriminating between surfaces before and after treatment. Although the compared roughness estimators were on different scales, a roughness estimation of the nanoscale surfaces was feasible, where other methods fail. The presented methodology can be applied widely and unambiguously for highly different method comparison tasks.

“…The modified starch obtained using LIU treatment may be more suitable for specific applications requiring enzymatic modification. 29 Conversely, LIU has the potential to elevate starch solubility by disrupting its granular structure. 20 Starch is insoluble in water due to the presence of a compact granular structure that restricts water access to the interior of the granules.…”

Starch derived from plants plays an essential role in pharmaceuticals due to its components Amylose and Amylopectin, which form essential granules for drug delivery. Its biocompatibility and cost-effectiveness make it indispensable in pharmaceutical formulations, facilitating controlled drug release and tablet breakdown. The effectiveness and safety of drug formulations are often hindered by challenges such as low solubility and stability. In order to overcome these obstacles, current research is focused on modifying the properties of starch. The goal is to improve its solubility, swelling, erosion, stability, and ability to release drugs. A promising solution that has emerged is ultrasound-based modification. This technique has shown great potential in transforming starch granules, leading to improved solubility, degradability, and control over drug release. Not only is this method efficient and quick, but it also has the added benefit of being eco-friendly. This discussion will explore the mechanisms behind the modification of starch based on ultrasound, delving into both the physical and chemical changes that occur in starch granules. The analysis explores the utilization of modified starch induced by ultrasound in the field of drug delivery, investigating its stability and compatibility with biological systems. By exploring the capabilities and difficulties associated with the use of ultrasound to change starch for the delivery of drugs, we highlighted its potential as a leading and effective methodology.

“…Treatment time is also a key parameter and not easy to determine. Some authors use a few seconds of treatment [98], claiming that longer treatment times did not produce a more significant effect, or the sample was damaged seriously [99], while others choose very long treatment times, sometimes up to 1 hour, without the destruction of the sample [97]. It is very difficult to compare the different treatments, as in most cases, the plasmas are different even if produced in the same device.…”

Can Plasma Surface Treatment Replace Traditional Wood Modification Methods?

Wood modification is an excellent and increasingly used method to expand the application of woody materials. Traditional methods, such as chemical or thermal, have been developed for the targeted improvement of some selected properties, unfortunately typically at the expense of others. These methods generally alter the composition of wood, and thus its mechanical properties, and enhance dimensional stability, water resistance, or decrease its susceptibility to microorganisms. Although conventional methods achieve the desired properties, they require a lot of energy and chemicals, therefore research is increasingly moving towards more environmentally friendly processes. The advantage of modern methods is that in most cases, they only modify the surface and do not affect the structure and mechanical properties of the wood, while reducing the amount of chemicals used. Cold plasma surface treatment is one of the cheapest and easiest technologies with a limited burden on the environment. In this review, we focus on cold plasma treatment, the interaction between plasma and wood compounds, the advantages of plasma treatment compared to traditional methods, and perspectives.
