A method was developed to include micro and macronutrients in keratin and collagen hydrolysates, in order to obtain new byproducts-bioemulsions (stable because of surfactants), with final goal of application as a new class of root fertilizers for cereals (e.g., corn). The newly obtained byproducts (bioemulsions based on surfactants) were characterized by: dynamic light scattering measurements, contact angle, optical microscopy and microbiological tests against fungal attack of Fusarium spp. and Botrytis cinerea. Better results were obtained for gemini surfactant based on sugar – polymethylene-α, ω-bis (N, N-dialkyl-N-deoxy-d-glucitolammonium iodides) due to the properties such as: biodegradability, nontoxicity and adherence to surfaces. The new fertilizer created in this research – bioemulsions based on surfactants, can support the general structure of the grains as well as the chlorophyll content, increasing the growth yield. The fertilizer is indicated for any type of crops and soils, with recommended use as additional fertilizer for plants (cereals) in the vegetation and growth phases, with a maximum need for nutrients.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"13 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":"126776009","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}

Footwear needs to move away from a linear pattern of growing consumption of planet resources towards a sustainable and more circular living where we use less resources and reduce emissions and climate change. To do so, the industry, whole value chain and consumers need to commit and take concrete actions.

The influence of carbon fibres nanoparticles (CF) on the rheological and physico-mechanical properties of the polyamide was studied. The nanocomposites based on polyamide/ compatibilizers/ polyethylene/carbon fibres nanoparticles were characterized by scanning electron microscopy (SEM) and Fourier transformation infrared spectrum (FT-IR) and in terms of physico-mechanical properties. The studied nanocomposites have higher values compared to the blank samples, and the requirements of the railway of impact strength of 5 KJ/m2. Carbon fiber concentrations greater than 1.5% result in decreases in impact strength values, similar to traction resistance values, but not lower than standard values. This leads to the conclusion that the percentages of carbon fibers in the range of 0.1-1.5% achieve maximum values of physical-mechanical parameters.","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":"128691996","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}

The effect of sequential modification of aqueous dispersions of montmorillonite with cationic and anionic compounds on the structural and charge characteristics of mineral dispersions was studied. The effect of chemical dispersion of agglomerates of aqueous montmorillonite dispersions after adding carbonate solutions was shown. The treatment of dispersions of original montmorillonite with sodium carbonate provides maximum dispersion of mineral aggregates by penetrating into the interstructural space of aluminosilicate packets, moving them apart and separating them. It was found that the modification of montmorillonite dispersed by sodium carbonate by adding basic chromium sulfate is accompanied by a change in the surface chemistry of the mineral and structural transformations. Structural changes are manifested by the formation of a developed structure of cationic montmorillonite. The cationic surface charge of montmorillonite and high specific surface of montmorillonite are important factors for ensuring effective adsorption of anionic dyes on the surface of the mineral. The efficiency of adsorption of anionic dyes on cationic montmorillonite is investigated. It was shown that the adsorption of dyes depended on the pH of the medium. The scheme of obtaining nanopigments, which were characterized by good сovering power, saturated and intense colour was proposed.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"89 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":"124792486","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}

Alongside this advantageous physical property, cellulose derivatives exhibit proper biocompatibility, biodegradability, thermo-gelling nature, and mechanical characteristics. Due to their high hydrophilicity, these biopolymers possess a great capacity to absorb large amounts of water into their structural chains, forming hydrogels with multiple biomedical applications, such as wound healing. Therefore, the main objective of this present work was to assess the rheological properties of some cellulose derivatives-based hydrogels. For this purpose, different commercial varieties of methylcellulose and hydroxyethylcellulose, two of the most used cellulose derivatives, were dispersed in water and stirred continuously until a clear and transparent hydrogel was formed. Depending on the quantities used of each biopolymer, hydrogels of different concentrations were obtained, from 3 to 20%. The topical semisolid systems were rheologically investigated at 23°C using a rotational viscometer and the rheograms of the experimental data were drawn. The hydrogels showed a non-newtonian pseudoplastic behaviour, which represents a requested requirement for topical semisolid systems, both in terms of conditioning, but also of spreading on the skin surface, improving the topical administration.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"50 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":"121541510","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}

The research used a quantitative approach through distributing an online questionnaire to people in Egypt in order to examine the research variables.

The findings showed that environmental knowledge has a direct impact on recycling intention; moreover, the mediation role of Internal perceived behavioural control and External perceived behavioural control is rejected.
