“…Due to the increase in intermolecular and intramolecular chain interactions of the HDPE matrix when mixed with the DE/ZnO nanocomposite, the HDPE mechanical characteristics did not statistically alter in elongation at break. Moreover, it could be assumed that the addition of DE/ZnO has no effect on the mechanical properties of HDPE [ 42 , 43 , 44 ].…”

One of the key factors of supporting the rapidly expanding seafood product industry in terms of quality control is the utilization of active packaging materials. Microorganisms are primarily responsible for the perishability and rapid disintegration of seafood. The incorporation of an inorganic compound, such as silica-based diatomaceous earth (DE), and a metal oxide, such as zinc oxide (ZnO), is proposed to develop active packaging materials with excellent antibacterial activity, minimized fishy odor, and brittleness at subzero temperatures. The mechanical, morphological, and physicochemical properties of these materials were investigated. The results show that the addition of DE/ZnO improved the antibacterial activity of high-density polyethylene (HDPE) samples by up to approximately 95% against both gram-positive and -negative bacteria. Additionally, it enhanced the Izod strength and stability at subzero temperatures of the samples. The odor evaporation test revealed that trimethylamine can be minimized in proportion to increasing DE/ZnO composite concentration. As a result, the development of active packaging materials from DE/ZnO composites is an emerging polymeric packaging technology for seafood products, wherein packaging and seafood quality are linked.

The aim of this study was to synthesize silver nanoparticles (AgNPs) using cellulose derivatives and to evaluate their antimicrobial potential. As effective reducing and stabilizing agents for AgNPs, cellulose derivatives, such as hydroxypropyl cellulose (HPC), methylcellulose (MC), ethylcellulose (EC), and cellulose acetate (CA), were used. Their ability to reduce silver ions as well as the size of the resulting AgNPs were compared. The formation and stability of the reduced AgNPs in the solution were monitored using UV-Vis analysis. The size, morphology, and charge of the AgNPs were evaluated. We found that, when using cellulosic derivatives, AgNPs with sizes ranging from 17 to 89 nm and different stabilities were obtained. The parameters, such as size and ζ potential indicate the stability of AgNPs, with AgNPs-CA and AgNPs-HPC being considered more stable than AgNPs-EC and AgNPs-MC since they show higher ζ potential values. In addition, the AgNPs showed antimicrobial activity against all reference strains and clinical isolates. MIC values between 0.0312 and 0.125 mM had a bactericidal effect on both Gram-positive and Gram-negative bacteria. The fungicidal effect was obtained at a MIC value of 0.125 mM. These results may provide rational support in the design of medical gauze products, including gauze pads, rolls, and sponges.

“…Subsequently, the MSD curves of water and hydrated protons have been calculated based on the simulated data of last 10 ns in Figure S2. The diffusion coefficients of water molecules and hydrated protons are important properties and were obtained by fitting the flat region of the MSD curves. It can be found that our simulation data is generally consistent with previous studies (Figure b). − …”

The hydrogen bond network (HBN) is of primary importance to the proton transport in Nafion. However, the evolution of the HBN in Nafion with water content and the underlying thermodynamics have not been revealed. In this study, the free energy of hydrogen bond formation is calculated based on an information-theoretic approach, indicating the formation of HBN in Nafion is a thermodynamically favorable process as the water content increases. In addition, the evolution of HBN in Nafion with water content including the topology and basic building blocks has been visualized and quantified by a ring statistics approach based on graph theory. Finally, the rearrangement dynamics and heterogeneity of HBN are also disclosed. This study provides a fundamental and comprehensive understanding of HBN in Nafion including the formation thermodynamics, topology, and rearrangement dynamics, which is useful for the design of high-performance proton exchange membranes.
