Characterization of Current Environmentally - Friendly Films
نویسنده
چکیده
The purpose of this study was to evaluate the physical and mechanical properties of environmentally-friendly films for fresh-cut lettuce. This objective was achieved by determining the gas transmission rates for oxygen, water vapor, carbon dioxide, and the thermal and mechanical properties of the films following ASTM standards D3985, F1249, F2476-05, D3418-03, and D882-02, respectively. Electromechanical testing and thermal analysis determined that biodegradable polypropylene (BPP) possessed similar mechanical and thermal properties when compared to the industry standard. This study suggests that BPP films may be used in place of traditional petroleum-based films currently used to package fresh-cut produce.

In this research, nanocrystalline Co-Fe coatings were electrodeposited on copper substrate. The influence of current density on different properties of the films at two pH levels was investigated. All the coatings showed nodular structure with rougher morphology at higher current densities. Due to anomalous deposition at higher current density, the amount of iron content increased and reached i...
متن کاملWhy Acting Environmentally-Friendly Feels Good: Exploring the Role of Self-Image
Recent research suggests that engagement in environmentally-friendly behavior can feel good. Current explanations for such a link do not focus on the nature of environmentally-friendly behavior itself, but rather propose well-being is more or less a side-benefit; behaviors that benefit environmental quality (e.g., spending one's money on people rather than products) also tend to make us feel go...
متن کاملSynthesis and Characterization of Colloidal Nanosilica via an Ultrasound Assisted Route Based on Alkali Leaching of Silica Fume
Colloidal nanosilica is currently being produced by various methods which are mainly high energy intensive and/or not environmentally friendly. It is therefore essential to develop new energy-efficient and environmentally friendly technologies. This paper introduces a new ultrasound assisted route based on alkali leaching of silica fume for synthesis of colloidal silica nanoparticles. The ef...
