Summary: Plastic-based food packaging causes a serious environmental problem, driving the need to develop biodegradable films, with starch as a potential substitute for petroleum-based plastic. While starch has many advantages, its low mechanical strength and water resistance can be overcome by using nanocellulose as a reinforcement in biocomposites for food packaging.

Summary: The effect of polyethylene glycol (PEG) and ZnO nanoparticles concentration on the rheological and structural properties of hydroxypropyl methylcellulose (HPMC) based film forming suspensions (FFS) were investigated. The results showed that the rheological properties of the FFS were not significantly influenced by the concentration of PEG and ZnO nanoparticles. The tensile strength of the HPMC film decreased and the water vapor permeability increased with increasing PEG concentration. However, the incorporation of ZnO nanoparticles improved the tensile strength and barrier properties of the HPMC film.

Summary: In this study, an (alpha-Al2O3 + ZrB2)/Al composite was prepared by promoting reactions among Al, ZrO2, and B2O3 powders. The nano-particles, with alpha-Al2O3 particles around 50 nm and ZrB2 particles around 10 nm in size, were mainly distributed along grain matrix boundaries, forming particle networks. The composite exhibited well-matched tensile strength and elongation, with the particle networks playing a positive role in piling up of dislocations during the tensile process.

Summary: This study aims to enhance the mechanical properties of alginate aloe vera composite films by adding organic fibers like carboxymethyl cellulose (CMC) and hydroxypropyl methylcellulose (HPMC). The addition of both CMC and HPMC improved the tensile strength and elongation at break of the films. However, increasing the fiber concentration resulted in a decrease in mechanical properties. CMC reduced the water solubility of the films, while HPMC increased it.

Summary: In this study, nano-SiO2 was incorporated into polyvinyl alcohol/xylan matrix to prepare an inorganic-organic hybrid composite film with improved mechanical and barrier performance. Adding 1% nano-SiO2 increased the contact angle of the composite film from 89.6 degrees to 110.4 degrees, increased the tensile strength from 11.2 to 14.8 MPa, and decreased the oxygen permeability from 1.83 to 0.27 (cm3·µm)/(m2·d·kPa), corresponding to a 23% increase in contact angle, 32% increase in tensile strength, and 85% decrease in oxygen permeability. These results suggest that the nano-SiO2 modified xylan film has great potential as a barrier film in food packaging.

Summary: In recent decades, the synthesis of coordination complexes with high catalytic efficiencies has been a topic of interest for bio-inorganic chemists. Two trinuclear mixed-valence manganese complexes have been synthesized and shown to exhibit catecholase-like activity in acetonitrile medium. These complexes have efficient oxidizing activity and can fully oxidize the substrate at a high catalyst-to-substrate ratio. This study is the first to explore the catecholase-like activity of trinuclear species and the second to report pseudo-zero-order kinetics.
