It is generally considered safe for use in food, and its production using existing manufacturing processes makes it cost-efficient. PLA is a hydrophobic and crystalline polymer. PLA membrane was fabricated using Polyethylene Glycol (PEG) and N-Methyl-2-Pyrrolidone (NMP) by the phase inversion method using Tween 60 as an effective emulsifier additive. Tween 60 is an ethoxylated sorbitan ester-based fatty acid (stearic acid). The prepared PLA membrane structure and morphology were studied by Scanning Electron Microscopy (SEM), and the performance of the prepared membrane was evaluated by measuring porosity, pore size, and tensile strength. The tensile test confirmed that PLA membranes demonstrate allowable mechanical properties. After completing this observation, it was found that some amount of Tween 60 increased the water content pore size without disturbing polymer chain entanglement and enhanced water permeability through the membranes.","PeriodicalId":492025,"journal":{"name":"i-manager's journal on material science","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710115","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}

Especially the works where ink and colors used are not sensitive to water. In this research, starch paste with a ratio of 3 to 1 (3 parts paste and 1 part water) was used. The use of starch paste increased the pH of the samples coated with this paste compared to the control samples without paste. The samples coated with starch paste had the lowest pH after moist-heat aging compared to other samples. The samples coated with starch paste showed the lowest amount of color changes (∆E) after moist-heat aging and light aging, respectively. The use of starch paste increased the tensile strength of the samples. After light aging and moist heat aging, the tensile strength of the samples decreased compared to the previous stage, but the tensile strength of the samples coated with starch paste increased compared to the control samples without paste. The results of the adhesion resistance test of the samples showed that the amount of adhesion of the samples decreased to a greater extent after moist-heat aging compared to light aging.","PeriodicalId":492025,"journal":{"name":"i-manager's journal on material science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710762","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 better amorphous nature observed for the 70 PAN:30 NH4CF3SO4 composition with the addition of 1-4 wt% of ZrO2 nanofillers and structural complexation studies of NCGPEs were confirmed by the X-ray Diffraction (XRD) technique. The microstructural studies and particle size can be revealed by the Scanning Electron Microscopy (SEM) technique. DC conductivity studies reveal the ionic conductivity performance on the effect of temperature and composition wt% of nanopowder. The ionic conductivity studies were observed for 70PAN:30NH4CF3SO4 with nanopowder ZrO2 concentrations ranging from 1-4 wt%. The sample containing 3% ZrO2 exhibits the highest conductivity order of 4.20 x 10-4 S cm-1 at room temperature (303K) and 4.65 x 10-3 S cm-1 at 373 K.

The research explores the potential health benefits of this complex, extracted from natural sources, in enhancing immunity and leveraging its heme-like properties. The prepared water-soluble complex was subjected to a comprehensive characterization process utilizing various analytical techniques, including UV-Visible spectroscopy, Powder X-ray Diffraction (PXRD), and Fourier-Transform Infrared (FT-IR) spectroscopy. The characterization results revealed the compound's structural properties, optical behavior, and molecular interactions, providing valuable insights for its potential applications in various fields. The complex was also evaluated for its photocatalysis capabilities. The results of the study indicate that the prepared [Fe III(EDTA)H2O]- complex exhibits structural and spectral similarities to Hemin Iron(III) complex. This suggests that the [Fe III(EDTA)H2O]- complex could potentially have similar biological or catalytic properties to the Hemin Iron(III) complex, opening up new avenues for research and applications.

The adoption of biodegradable materials in consumer products has gained significant attention. This study comprehensively investigates the incorporation and impact of biodegradable materials in various consumer product categories, including packaging, textiles, electronics, personal care, and cosmetics. The study explores a diverse range of biodegradable materials, including bioplastics, natural fibers, and innovative biodegradable electronics components, while assessing their suitability for reducing environmental footprints. The environmental consequences of conventional plastics in consumer products are outlined, emphasizing the urgency of transitioning to eco-friendly alternatives. Case studies from industries at the forefront of sustainable practices exemplify the successful integration of biodegradable materials, and a critical evaluation of challenges, including cost, performance, and end-of-life management, underscores the need for holistic solutions. Regulatory frameworks and labeling standards are examined in the context of promoting transparency and consumer choice. By discussing recent trends and future prospects, and highlighting the pivotal role of biodegradable materials in fostering sustainability and reducing waste generation in the consumer product landscape, this study offers insights into the pivotal shift towards environmentally responsible consumer product design and encourages continued research and innovation in this transformative field.","PeriodicalId":492025,"journal":{"name":"i-manager's journal on material science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710936","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}
