According to the most of research and experiments that relevant with the characteristics of solid earth materials, mainly there were obtained and disclosed some various outstanding physic-chemical characteristics of a large number of earth materials including the applications of material processing, nano-materials, composite materials and hard materials. In the existing research there were expected to characterize some selected clay varieties, a dolomite variety and a feldspar variety which are available in Sri Lanka towards the developments especially in some advanced chemical and catalytic applications. The X-ray fluorescence (XRF) spectroscopic analysis and Scanning electron microscopic (SEM) analysis were done for all of selected materials. The X-ray diffraction (XRD) analysis was done for three different selected clays and the Fourier transforms infrared (FT-IR) spectroscopic analysis was done for three different clay types and for a dolomite variety. According to the obtained results for the research, there were found the presence of at least 75% of Fe as the major element in each of clay with some other trace metallic elements such as K, Ti, Ca, Ba and Zr in such clays, kaolinite, montmorillonite and some of Fe minerals namely as muscovite and glauconite in such clays with quartz as a non-clayey mineral. There were found some higher amount of calcite in the selected dolomite with a trace amount of K and also there were found some higher K and Ca amounts presence in the selected feldspar rocks. When comparing the obtained results with past research out comes and modifications of materials, it seems that these materials will be much useful in the industrial applications such as the catalytic activities, waste water treatment applications in the removal of heavy metals due to the adsorption capacity, ion exchanging materials to remove unnecessary ions from waste water and in the removal of hardness from waste water due to the adsorption capacity of dolomite.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129211152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After grinding, it is functionalized with monoethylene glycol (MEG) in a proportion of 20% at a temperature of 60°C. By recycling and reusing vulcanized rubber waste (NBR), as well as by means of advanced technologies, it is possible to contribute to the improvement of product quality, the protection of the environment through waste recycling, and most importantly the protection of human health through the elimination of noxious substances during their burning and, of course, increasing the turnover of economic agents. The polymer compounds obtained after conditioning at ambient temperatures were characterized according to the standards in force for the footwear industry, in terms of physical-mechanical normal state and accelerated aging at 70°C for 168 h and FT-IR spectroscopy.

The active ingredients of basil essential oil can be used in perfumes, pharmaceuticals, medicine, cosmetics or spices. In this study, the essential oil of basil was obtained by hydrodistillation in the Clevenger continuous extractor. It was characterized by GC-MS and 53 constituent compounds were identified. The majority compounds were highlighted: linalool, 64,569%, p-allyl anisol, 5,163%, Eucalyptol, 3,745%, α-Cadinene, 3,510%. Kovats indices were calculated and FT-IR analysis was performed to confirm the specific constituent compounds. The essential oil of basil was microbiologically analyzed against Escherichia coli (ATCC 10536) Gram-negative bacteria and against Staphylococcus aureus (ATCC 6538) Gram-positive bacteria by diffusometric working method. Antibacterial activity was determined by measuring the diameter of the inhibition zone around the samples. Samples of filter paper and cotton fabric were used to simulate shoe lining and bandages. Basil essential oil has resistance against the tested strains, observing the increase of the inhibition zone with the increase of the amount of essential oil used in treatments (20 μL, 30 μL, 50 μL). The results showed that Ocimum basilicum L. may be a good candidate as a plant-derived antibacterial agent for medical footwear, wound dressings and other medical applications.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133410644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, it was addressed the issue of ensuring the physiological and comfort parameters when wearing leather substitute shoes. The aim of the paper is to analyze how the sanogenetic indicators influence the hygienic properties of footwear products starting from the porosity of the materials subjected to experimental determinations. Poromeric skin substitutes will be used, which allow the passage of water vapor and air. Both types of leather substitutes for shoe uppers and some types of textile materials for linings will be subjected to laboratory analysis, using the pycnometric method. In conclusion, the values obtained for porosity fall between 47 and 58%, limits also provided by the specialized literature. It is noted that the porosity values of leather substitutes are close to those of chrome-tanned leather, so as a result, the value of leather substitutes use will increase (they have sanogenetic properties similar to natural leather). Currently, leather substitutes are used more and more in the manufacture of footwear products, because they maintain a thermal transfer balance between the foot and the surrounding environment, favoring the elimination of moisture produced by the foot when wearing the footwear in the outdoor environment.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133794828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, it has been tried to overcome drug resistance, especially with the use of herbal products in combination with existing drugs. In this study, we aimed to investigate the effectiveness of eucalyptol in combination with acyclovir. A Vero cell line was used for toxicity tests and viral culture isolation studies in the study. The non-toxic concentrations of eucalyptol and acyclovir were determined by the MTT method. Antiviral efficacy studies were performed within non-toxic concentrations. Antiviral activity was determined by calculating the IC50 values of the compounds against HSV-2. In addition, it was evaluated by the RT-PCR method. The 50% inhibitory concentration (IC50) and Fractional inhibitory concentration (FIC) index values determined during 24 hours and 48 hours of action showed that Eucalyptol exhibited a potent activity. This efficacy was found to be stronger when used in combination with acyclovir. These results show that the combination of Eucalyptol and acyclovir may be beneficial against resistant HSV infections. We suggest that the results of these studies, which are planned as in-vitro, be supported by in-vivo studies.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128017809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this sense, it is proposed to use compounds that can incorporate and block the diffusion of the substances back into the environment. To achieve this, a mixture of epoxy polymers, biphenol A and biphenol F, will be used, in a 1:1 ratio, which after the polymerization reaction, with Ancamine 2686, will result in an inert mass.

Noble furs have always had a special role in people's lives, over time the mankind crossed the seas and continents in search of the precious furs (noble furs). Since the 17th century, noble furs have been so appreciated that they have been used in certain geographical areas instead of money. In the past, noble furs were used only by those with a very good financial situation, but nowadays, noble furs are used on a large scale to make clothes, collars, and hats. The main purpose of this article is, therefore, to determine which of the two noble furs has superior physical and mechanical qualities. The reason why these two furs were chosen was that one is believed to be an imitation of the other on the market. The two types of fur were carefully analyzed by subjecting them to different types of physical-mechanical tests, the most relevant being: “Determination of tensile strength and percentage elongation”, “Determination of tear strength”, “Determination of shrinkage index”, “Resistance at plucking the fur”. All the tests were performed according to actual standards in ICPI accredited laboratory. The obtained results showed that although the two noble furs seem similar at first sight, the original has a superior quality, but also nutriette fur has proven to have some appreciable physical-mechanical properties.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116792880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to determine which lacquer emulsion or emulsions are causing this situation, which may result in cost, time, and quality losses. For this reason, in this study, firstly, three different lacquer emulsions, namely Nitrocellulose, Cellulose Aceto Butyrate and Polyurethane, were applied to the leathers dyed with the same finishing composite (base coat) at the final stage. These lacquer emulsions are widely used in leather finishing. Water-soluble forms of these materials, including solvent-soluble types, were chosen for use in this study because they are more environmentally friendly and easier to apply. After that, leather colors were analyzed for color parameters determination by using Konica Minolta brand CM 3600d Spectrophotometer and compared with the color changes before and after the lacquers were applied. Finally, The NCSS (Number Cruncher Statistical System) 2022 Statistical Software (NCSS LLC, Kaysville, Utah, USA) program was used to statistically evaluate the results. As a result, it was attempted to identify the lacquer emulsions that causes the color change in the leather.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115683121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
