English Proficiency and Cultural Adaptivity among International Female Students in the US Job Market
Get PDFThe abstract presents a study conducted in 2021 at Pittsburg State University aiming to investigate the English proficiency and cultural adaptivity of female international students seeking employment in the USA. Employing a non-experimental quantitative methodology with a descriptive design, the research focuses on 50 female international students from Pitt State who are actively searching for employment. The study contains 20 survey questions to assess the participants English proficiency and cultural awareness. The main objective is to establish the relationship between English proficiency and cultural adaptivity among female international students in pursuit of employment opportunities. By analyzing the survey data, the study aims to provide insights into whether English proficiency impacts the ability of female international students to adapt to cultural changes in their job search. Notably, the research does not involve grading participants based on their English proficiency assessment results. The findings of this study can contribute valuable insights to academic institutions, employers, and policymakers involved in supporting the integration and success of female international students in the US employment market
Biobased Vitrimers via Melt-Polycondensation Process with Good Extensibility, Reprocessability, and Self-Healable Properties
Get PDFThe global sustainable development of the polymer industry is dependent upon the ease of synthesis and the replacement of petroleum-based elastomers with biobased equivalents. Here, we suggest the condensation polymerization of aliphatic diacids such as glutaric acid, pimelic acid, azelaic acid, and 1,4-butanediol with a catalytic amount of glycerol as a curing agent and dithiodicarboxylic acid as the dynamic covalent crosslinker to fabricate highly stretchable elastomers. The elastomers showed good extensibility, reprocessability, and self-healable properties. The molecular characterization and thermo-mechanical properties of the elastomer were investigated using Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, and Dynamic Mechanical Analysis. The self-healing performance of the elastomers is ascertained by SEM analysis, where the presence of -S-S crosslinker provides a disulfide metathesis phenomenon which assisted in self-healing properties of the elastomer at low temperatures. The high elongation, thermal reprocessability, and self-healing nature of the polymers result in the successful preparation of biobased vitrimeric elastomer. The simplicity of preparing the elastomers by polycondensation process suggests that there are promising possibilities to generate environmentally friendly sustainable polymers with stimuli-responsive properties
Blends of Epoxidized Alkyd Resins Based on Jatropha Oil and the Epoxidized Oil Cured with Aqueous Citric Acid Solution: A Green Technology Approach
Get PDFAlkyd resins were made from jatropha oil using a two-step method that included alcoholysis and polyesterification reactions, using 100% Phthalic Anhydride. To enhance their performance properties, the resins were mixed with different wt % of epoxidized jatropha oil (EJO) and aqueous citric acid, without the need for additional catalysts or solvents. Blending was facilitated via epoxidation of the alkyd resins. The prepared blends were characterized by Fourier transform infrared and NMR (1 H and 13C) spectroscopy studies. It was noted that blending led to significant improvements in properties such as curing time, chemical resistance, scratch hardness, thermal stability, and tensile strength of the alkyd resins. In particular, there was a noticeable increase in tensile strength by 3.18 MPa and thermal stability by 42°C when the blends contained 50% EJO. The results indicate the strong influence of the amount of EJO and citric acid on the performance of the alkyd resins. Additionally, the thermal and mechanical properties of the cured films could be further enhanced through post-curing at 160°C. Overall, the results of this study suggest suitability of these blends in surface coating applications
Closing the Loop: Glycolysis Via Bio-Based Solvent and Regeneration of Bio-based Polyurethane Foams
Get PDFThe quest for sustainable and renewable materials is driving a paradigm shift towards a bio-based economy, propelled particularly by the imperatives of the Sustainable Development Goals (SDGs). The increased use of bio-based polyurethane foams (bio-PUFs) in industrial applications presents a challenge for researchers to develop innovative recycling methodologies conforming to evolving sustainability standards. This research represents an innovative approach to the recycling of bio-PUFs through depolymerization via Glycolysis, employing commercially available bio-based solvent. The degradation and recovery of polyol were validated through FTIR and NMR analysis, confirming the presence of amine groups, urethane linkages, and other byproducts. High yields (over 93%) of recovered polyol were achieved within comparable timeframes using both bio-based and traditional petroleum-based glycolysis agents. Comparative analyses revealed superior physical and chemical properties of bio-based recovered polyol over its petroleum-based counterpart. The resulting recovered polyol (RP) was utilized to fabricate new PUFs replacing up to 20% w/w of the virgin polyol, exhibiting physical characteristics like virgin PUFs with negligible deviations. Finally, this study outlines the enhanced circularity within the value chain by closing the loop of bio-PUFs through sustainable glycolysis processes, thus contributing to the advancement of circular economy principles
