High energy influxes increase the complexity of passive calorimetric probe measurements because of an increasing temperature of the surrounding materials like the probe holder. This leads to a distinctively different evolution of the probe temperature compared to low energy influxes. Different established methods for the analysis of passive calorimetric probe data are presented and it is shown that they are not applicable for high energy influx measurements resulting in the requirement of a novel analysis approach. Such an approach is given in this paper by the combination of the exponential and the linear method. The high energy influx measurements are studied for a commercial atmospheric pressure plasma jet, in order to illustrate our suggested modified approach.

“…Various authors studied the properties of thin films based on SiO x depending on the experimental parameters as the type of working gas and precursor, the design of injection the precursor mixture into the plasma jet region, and also the structural and chemical properties of the coatings. [35][36][37][38][39] The formation and synthesis of nano and micro particles in the so-called "dusty plasma" is one of the promising "dry" and direct methods for generating particles with specified sizes for various purposes in nanotechnology and materials engineering. 40) Despite the fact that the process of particle formation in a low-pressure reactive plasma with various gas precursors has been studied in detail in recent decades, the formation of particles in atmospheric-pressure plasma from organosilicon precursors is still poorly understood.…”

In this work, the results of SiO x thin film deposition by an atmospheric pressure plasma jet using HMDSO (hexamethyldisiloxane) as precursor are presented. The experiments were performed for different process parameters like initial applied power, substrate to nozzle distance and speed of the moving substrate holder. In order to determine the properties of deposited films the samples were analyzed by scanning electron microscopy, transmission electron microscopy, atomic force microscopy and profilometer. The formation mechanism of particles and their size distribution depending on the process parameters are described and discussed. The results show the possibility to change properties of deposited films and particle formation by tuning the experimental settings.

“…Noeske et al [3] showed that plasma treatments can be utilized to improve the adhesive strength of several polymer surfaces. Successful depositions of anticorrosion protective coatings after the plasma pretreatments on aluminum and copper substrates were done in the work of Regula et al [4] . Even though lots of successful results were reported on the topic, it needs to be admitted that it is possible to achieve the highest output efficiency by using a combination of chemical treatment (initial surface degreasing) and atmospheric pressure non-thermal plasma treatment (fine cleaning and surface activation).…”

This paper is aimed to show the influence of initial chemical pretreatment prior to subsequent plasma activation of aluminum surfaces. The results of our study showed that the state of the topmost surface layer (i.e. the surface morphology and chemical groups) of plasma modified aluminum significantly depends on the chemical precleaning. Commonly used chemicals (isopropanol, trichlorethane, solution of NaOH in deionized water) were used as precleaning agents. The plasma treatments were done using a radio frequency driven atmospheric pressure plasma pencil developed at Masaryk University, which operates in Ar, Ar/O2 gas mixtures. The effectiveness of the plasma treatment was estimated by the wettability measurements, showing high wettability improvement already after 0.3 s treatment. The effects of surface cleaning (hydrocarbon removal), surface oxidation and activation (generation of OH groups) were estimated using infrared spectroscopy. The changes in the surface morphology were measured using scanning electron microscopy. Optical emission spectroscopy measurements in the near-to-surface region with temperature calculations showed that plasma itself depends on the sample precleaning procedure.
