Importantly, they exhibit high recyclability. While these materials are relatively stable and corrosion-resistant in most environments, they are often subjected to corrosion and wear in harsh environments. Coatings are the most common method of corrosion protection of aluminium and its alloys. Coatings can improve not only corrosion resistance but also wear resistance, and can add functional properties to the surface. In the present review, the coatings are summarised in five groups: (1) barrier aluminium oxide coatings, including anodised coatings, plasma electrolytic oxidised coatings, coatings deposited by atomic layer deposition, and by hydrothermal treatment, (2) conversion coatings including zirconium, titanium, trivalent chromium, and phosphate (3) metallic coatings comprising clad and electroplated metal coatings, (4) organic coatings comprising powder and liquids organic coatings, and sol-gel coatings, and (5) inhibition and wettability control coatings, comprising coatings incorporating inhibitors or nanoparticles and superhydrophobic coatings. The review focuses on production methodologies and the physical-chemical characteristics of coatings. Advantages and potential shortcomings of individual coatings are discussed in terms of their use and corrosion protection.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"11-30"},"PeriodicalIF":1.3,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A reverse phase high performance liquid chromatography method with UV-Vis detection was used to quantify the following biomarkers: coumarin, cinnamic acid, cinnamaldehyde and eugenol. A total of 23 cinnamon samples were analysed and processed using chemometric methods. Besides commonly used principal component analysis, uniform manifold approximation and projection was also used for exploratory analysis. Next, combination of dimensions reduction and classification algorithms were used for the development of 16 classification models. The models were validated using the bootstrapping resampling method. The best classification was achieved with the combination of principal component analysis - regularised discriminant analysis model with an overall accuracy of 84.0% and 89.2% in discriminating cinnamon species and their geographical origin, respectively. In addition, the samples were successfully classified according to their shape and whether the cinnamon samples were certified as \"bio\" organic.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"279-287"},"PeriodicalIF":1.3,"publicationDate":"2026-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It reduces the effectiveness of therapy and worsens cancer patients' prognoses. However, it confirms a wide range of molecular interactions as well as the complexity of the human organism. Our previous research confirmed the functionality of the erythropoietin receptor (EPOR) in ovarian and breast cancer cells, as well as its relationship to these cells' sensitivity to specific therapies. The current study demonstrates that EPOR overexpression in human ovarian adenocarcinoma cells A2780 is directly linked to paclitaxel resistance. Furthermore, EPOR overexpression results in morphological changes that vary according to the pattern of EPOR isotypes expressed. In this regard, the most interesting result appears to be the change in the shape of the T clone, which has a tendency to form spheroidal structures. In addition, functional enrichment analysis demonstrated that EPOR-associated differentially expressed genes are involved in several biological and cell processes. Indeed, a T clone with a single 68 kDa EPOR isotype demonstrates significant resistance to paclitaxel therapy and is associated with the upregulation of tubulin beta 6.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"73 1","pages":"258-266"},"PeriodicalIF":1.3,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147589341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
