“…The results of hardness and reduced Young's modulus measurements using the nanoindentation method are shown in Figure 13. The coatings have a hardness of 8-12 GPa range and a reduced Young's modulus of about 110-160 GPa, which is consistent with the literature results for the a-C layers with a C sp 3 − C sp 3 bond content in this range [65][66][67][68]. Notably, the summary of the results of the mechanical properties is close to the summary of the sp 3 /sp 2 ratio shown in Figure 11.…”

The Amorphous Carbon Thin Films Synthesized by Gas Injection Magnetron Sputtering Technique in Various Gas Atmospheres

This work presents the potential for using pulsed gas injection to produce amorphous carbon films. In this experiment, the frequency of injecting small amounts of gas was used to control the pressure amplitudes, thus achieving the conditions of plasma generation from stationary, through quasi-stationary, to pulsed oscillations of pressure. In addition, we used various gases and their mixtures, an alternative to argon. In the experiment, we studied the energy state of the plasma. The films were examined for phase and chemical composition, surface morphology, and optical and mechanical properties. We determined low-frequency pulsed gas injections to be conditions favorable for C(sp3) − C(sp3) bond formation. The plasma generated by gas injections is better ionized than that generated by static pressure. Pulsed conditions favor the plasma species to retain their kinetic energy, limiting the probability of intermolecular collision events. Since helium has a relatively high ionization energy, it is a practical addition to sputtering gas because of the increasing sp3 content in the films. The electrons created by helium ionization improve the plasma’s ionization degree.

“…A particular case is represented by relatively small metal processing establishments [14] that, due to the technologies used, handle toxic substances or generate such substances as waste during their operations. Welding facilities [15], surface treatment operations [16], various types of coatings application [17,18], including special coatings [19,20], and window manufacturing [21] can be mentioned in this regard. Given the substantial resources involved in the construction and maintenance of protective systems, a thorough identification of hazards is essential.…”

Abstract. The operation of the upper-tier establishments, which are prone to a major accident hazard, poses a real threat to the public in terms of health and potential environmental pollution. Therefore, the norms of EU directives seek to introduce as much transparency as possible to the operation of upper-tier establishments. The purpose of this article is to give an overview of the rules concerning the issue of information provision by the establishment to both the public and the relevant state and EU authorities. The following part of the article will provide a brief analysis of how the posting of public information on the websites of the upper-tier establishments looks like in practice.

“…The demand for scientific support also arises in the case of particularly advanced technologies associated with coatings [41][42][43] and surface layer [44]. This primarily includes DLC coatings [45][46][47] and ESD coatings [48][49][50], as well as separation issues [51]. In any of these cases, analytical and statistical support is necessary [52], including experimental design methodology [53][54][55] and non-classical approaches [56][57][58].…”

Abstract. The work is based on a literature review in the field of commercialization of scientific research – it presents various definitions of commercialization, the concept of indirect and direct commercialization, as well as ways of financing the commercialization of research results. The aim of the work is to present and learn about various approaches to the concept of commercialization, to show what forms the process of commercialization of research results takes place and how it can be financed. The aim is to identify and analyze the research area, because the work is an introduction to practical research and the creation of a model for the commercialization of scientific research results in the largest research network in Poland, dealing with i.e. providing attractive and competitive technological solutions.
