While 3D printing reshapes the physical realm by redefining how objects are manufactured, multimedia transforms the digital landscape, influencing how information is presented and consumed across diverse domains. 3D polymer printing, known for its layer-by-layer additive manufacturing process, has found a symbiotic relationship with multimedia, integrating visual, auditory, and interactive elements into the 3D printing realm. The research paper discusses how current and future 3D polymer printing can assist media industry through enhanced learning, interactive education experience, customized content, augmented and virtual reality, film and animation industry, as well as promotion of environmentally friendly practices. The versatility of 3D polymer printing has led to its widespread adoption across diverse industries, offering new possibilities in design, prototyping, and production. The tangible and interactive nature of 3D-printed objects enriches multimedia content across various industries.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431235","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}

Saccharin (A) is synthesized by adding hydrochloric acid to sodium saccharinate salt, with continuous stirring for 2 h. Mannich base derivatives (A1, A2) are prepared by reacting sulfanilamide with saccharin and benzaldehyde derivatives, using absolute ethanol as a solvent. Several complexes of Mannich bases (A3–A6) are obtained by reacting equimolar amounts of Mannich base derivatives (A1, A2) with the metal salt solution of cobalt and cadmium (MCln.XH2O), using ethanol as a solvent. The synthesized compounds and complexes are characterized using various spectroscopic techniques, including FT-IR, and 1H, 13C-NMR spectroscopy, and elemental analysis (C.H.N.S.). Additionally, their melting points, purity, molar conductivity, and magnetic susceptibility are determined. The impact of some prepared compounds and complexes on the growth of two antibiotic-resistant bacterial strains, namely the gram-negative Pseudomonas Aeruginosa and the gram-positive Streptococcus Mutans, is studied. Amoxicillin, Ampicillin, and Ciprofloxacin are used as a control antibiotics. Some of the synthesized compounds exhibited significant inhibitory activity against the tested bacterial strains. Molecular docking studies are conducted for the compounds (A1, A2) against Pseudomonas Aeruginosa using the MOE software (2009). The energy minimization process is employed to achieve the most stable conformation (lowest energy barrier) for these compounds.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431518","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}

These zeolites are employed in the catalytic thermal structural reforming process of naphtha distillates (35–200 °C) under initial temperature conditions (100, 150, 200, 250, 300, 350 °C) using a constant catalyst ratio. The zeolites, prepared in two forms, 1% by weight, and with a reaction time of 1 h, are first tested to determine the optimal temperature. Subsequently, the catalyst ratio and reaction time are adjusted based on the initial conditions for each catalyst, to establish the optimum conditions for unmodified zeolite at a temperature of 350 °C, a catalyst ratio of 3%, and a reaction time of 3 h. For nickel-modified zeolite, the optimal conditions are found to be a temperature of 300 °C, a catalyst ratio of 3%, and a reaction time of 3 h. The catalysts exhibited the ability to form rings and facilitate hydrogenation reactions, resulting in the preparation of aromatic compounds that reach threefold their original concentration. Specifically, the concentration increases from 7.1% to 23.61% in the nickel-modified catalyst.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431588","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}

This comprehensive article delves into the intricate dynamics of this issue, exploring the current landscape of chemical usage trends, and their environmental repercussions. It critically assesses the existing legal framework on both national and international levels, highlighting challenges in enforcement and the associated public health, and safety concerns. The discussion extends to proposed reforms, emphasizing the need for a strengthened legal framework, and increased community engagement. Case studies offer valuable insights, examining successful models and failures that shape lessons for future policymaking. The article further explores the role of technological advancements in enhancing monitoring and regulatory efforts and advocates for collaborative approaches involving government bodies, industries, and local communities. In conclusion, the article underscores the necessity of finding a delicate balance between economic progress and environmental responsibility. Through a multifaceted approach that incorporates legal reforms, technological innovations, and collaborative strategies, the future outlook envisions a harmonious coexistence of development and sustainability in the regulation of chemical usage outside governorate centers.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431624","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}
