“…The few agglomerations that appeared within the morphology for the PVA-ALG-10CNC nanocomposite implied that the content of 10 wt.% CNC might influence the structure of the nanocomposite films [3,53]. UV-vis spectroscopy was used to measure the optical transparency of nanocomposite films of PVA-ALG matrix filled with different concentrations of CNC and to evaluate the dispersion of CNC within it [54,55]. Transparency is an interesting factor to assess the quality of films for different applications, especially in food packaging [19,29].…”

In this work, the Juncus plant was used as an abundant and sustainable raw material for the production of cellulose nanocrystals (CNC). Herein, cellulose nanocrystals were prepared via sulfuric acid hydrolysis exhibiting a needle-like shape morphology, with an average diameter of 6.8 ± 1.8 nm and length of 457 ± 76 nm, arising to an aspect ratio of 59. Moreover, X-ray diffraction and TGA show that the CNCs exhibit high crystallinity and good thermal property respectively compared to other sources. Further investigation was conducted by preparing novel bio-nanocomposites through the incorporation of CNCs into the polyvinyl alcohol- alginate (PVA-ALG) blend matrix. Thus, giving enhanced properties compared to the pure matrix, particularly the mechanical properties due to the good interfacial adhesion, confirmed by FTIR analysis, while maintaining good transparency at low CNCs concentration, which is required for packaging application.

The aim of this study is to assess the state-of-the-art situation of mechanical compressors with thermal compressor systems in combined cooling systems and their ability to provide the required cooling effects with lower energy consumption than traditional cooling systems. The integrated systems have various advantages such as a broad temperature range, low energy consumption, and more flexibility in operating conditions. A comprehensive review of thermal‒mechanical combined cooling systems is presented in terms of its principles, applications, different configurations, and various heat source systems. Two types of thermal compressor systems are included in this study. The first one is the absorption system that uses a liquid‒vapor working pair in its thermodynamic cycle. Additionally, the second type is the adsorption system that utilizes a solid‒vapor working pair in its thermodynamic cycle. It is concluded that continuing technological innovations are vital for sustainable cooling. Technological developments can lead to cooling that is both inexpensive and energy-efficient.
