Special Issue Information

Dear Colleagues,

The main application of coatings is corrosion protection. Corrosion generates huge economical costs. According to the NACE International 2016 report, the costs of corrosion on the worldwide scale amount to 3.4% of the Gross Domestic Product—an unimaginable quota of USD 2.5 trillion. More than 50% of that quota consititutes costs related to coatings, as they are the most important and most frequently applied materials to protect metal structures against corrosion. Coating a metallic surface with an organic or composite organic–inorganic paint is an old but still vital and developing technology of corrosion protection. New types of paints, new methods and tools of their application, new structures of multilayer organic and composite coatings, as well as new methods of surface pretreatment before paint application, are being developed. Among the newest ideas, self-healing coatings, superhydrophobic coatings and self-cleaning coatings may be quoted. Only approximately 50% of paints are applied for the aim of corrosion protection. Other applications are decorative and functional coatings (self-lubricating or anti-reflection, for example). The surface may be protected from corrosion not only by organic or composite coatings, but also by plating the layer of other metals by the hot-dip method, electroplating, electroless deposition or surface treatment.

At the same time, coating technologies is a branch of materials science. Developing new coating technologies engages knowledge from many fields of science, like surface physics and chemistry, electrochemistry, organic and inorganic chemistry and many others. Research in the field of coatings engages the newest and most sophisticated methods of surface investigations, like frequency sum generation spectroscopy or positron annihilation spectroscopy. Computer-assisted mathematical modeling is also widely applied in the design of novel coatings.

Recently, we have observed growing interest in research devoted to coatings in Poland. Many excellent papers describing investigations in that field of science authored by scientists from Poland appeared in scientific and technical journals, including our journal Coatings.

To celebrate our achievements in that field, this Special Issue is inviting submissions on state-of-the-art of coatings research, including energy conversion, electronic devices in unlimited topics, wearable and flexible films, and bio-inspired materials, and devices.

This Special Issue will constitute an overview of coatings, thin and thick films, and surfaces and interface research activities in Poland. Research topics include, but are not limited to, the following:

  • Thin and thick films
  • Processes for coating deposition and modification
  • Characterization techniques
  • Functional, protective, and decorative coatings
  • Dyes, pigments, and their intermediates
  • Wear, corrosion, erosion
  • Coatings for high temperatures
  • Film materials for packaging
  • Applied surface science
  • Adsorption, adhesion, functionalization
  • Fundamental and functional properties of surface and interfaces
  • Theoretical and computational modeling of surfaces and interfaces
  • High surface area systems: colloids, nanoparticles, large interfaces
  • Membrane

It is my pleasure to invite you to submit manuscripts on the subject “State-of-the-Art of Coatings Research in Poland 2020” for this Special Issue. Full papers, communications, and comprehensive reviews are welcome. If you have any questions, please feel free to contact me.

Increasing occurrence of non-carious lesions in their various forms and etiologies requires reliable and valid diagnostic tools to register their distribution, severity, and progression and to become helpful in planning treatment. The aim of this work is to evaluate eight selected (etiological and non-etiological) indices of tooth wear/erosion, taking into account the subjective opinion of the researcher/operator and the patients being treated for eating disorders. The research sample included 60 people with symptoms of dental erosion. The study group included 30 patients suffering from eating disorders, recruited from three independent medical institutions providing eating disorder therapy. The control group consisted of 30 patients with no eating disorders, but with dental erosion caused mostly by a low-pH diet. The indices chosen for evaluation were: Tooth Wear Index by Smith and Knight; indexes by Lussi, Johansson et al.; Tooth Wear Index modified by de Carvahlo Sales-Peres et al.; Linkosalo and Markkanen modified by Ganss et al.; and index Oilo et al., BEWE, VEDE. The examination took place during three short visits. The study group (suffering eating disorders) and the control group (without eating disorders) evaluated the indices chosen for this research similarly. In the assessment made by both groups of patients, the usefulness and application benefits of the etiological indices set were not significantly different than in the case of a set of non-etiological indexes. An analogous opinion has been made by the operator/researcher as far, as the following aspects are concerned: the number of indexes criteria, order of difficulty in memorizing criteria and in the procedure of indexes application. According to this research, for the group at risk of dental erosive wear (with or without eating disorders), optimal research tools to evaluate dental wear occurred: index by Lussi, Tooth Wear Index modified by de Carvahlo Sales-Peres et al., BEWE, index by Oilo et al.

The problem of real treatment of teeth hypersensitivity is still important and unsolved. The main goal of the experiment was to calculate the possible toxic effects on the fibroblasts cells CCL-1™ (NCTC clone 929) caused by original preparation to reduce tooth surfaces’ hypersensitivity, compared to the marketable preparation Seal & Protect (Dentsply). The assessment was made through measuring lactate dehydrogenase (LDH assay). Lactate dehydrogenase releases from the cell’s cytoplasm to the culture medium as a result of cell membrane damage and lysis of the cells. The measurement is based on an assessment of the ability of LDH to oxidize lactic acid to pyruvic acid, which is dependent on the increase of the release level. The increase of LDH activity in the supernatants of cell cultures shows a relationship with the percentage of dead cells (increased cytotoxicity correlates with the increasing content of dead cells). In the LDH assay, both formulations evaluated after 24 h obtained results which were located below the control values. After seven days, the mean values obtained in cytotoxicity assay LDH are measurable and lower for the original formulation in comparison to the commercial one at the dilution of 1:5. At the dilution with 1:10 ratio, they are comparable and within the range of accepted values. At the maximal dilution of 1:15, the results are higher for the experimental formulation in comparison to the marketable formulation. The polymerization process is beneficial for the cytotoxicity test results in case of both tested preparations. Average values of cytotoxicity of both preparations attain an acceptable level of less than 22.6 ± 8.1%, reliant on the degree of dilution and the remark time. Original formulation is characterized by a greater homogeneity of results. The marketable preparation has a larger diversity of effects, dependent on the time of observation and attenuation; however, the cytotoxicity values are lower when paralleled to the experimental formulation in the test conducted after seven days. This should not have a disastrous effect on the pulp, as the values of both as the values of both preparations are within expected ranges. The obtained results allows to assume that will be possible to introduce the original formulation to the stage of clinical trials in the future. Full article
