In this study, biodegradable kefiran-chitosan-nanocellulose blend films were developed and their physical, mechanical, barrier, thermal and structural properties determined. Results showed that adding nanocellulose had not any significant effect on the thickness, moisture content and water solubility. Also, water vapor permeability, tensile strength and lightness increased and the elongation at...

Physical properties as well as antimicrobial activities against Escherichia coli O157:H7, Salmonella enterica, and Listeria monocytogenes of allspice, garlic, and oregano essential oils (EOs) in tomato puree film-forming solutions (TPFFS) formulated into edible films at 0.5% to 3% (w/w) concentrations were investigated in this study. Antimicrobial activities were determined by 2 independent met...

In this paper, taking account of the major physical and chemical mechanisms, such as: for polymer, shearing propertypermeability reduction, adsorption, inaccessible porous volumes, for gel, gelation speed, water viscosity changing with gel, permeability reduction, adsorption and retention in reservoir rocks, a three-dimensional, three-phase (oleic, vapor, aqueous) and six-component mathematical...

Plastic pollution, more specifically from food packaging and containers which account for the largest share of 36% current plastic production, is one greatest threats to natural environment human health. Thus, development alternative renewable plastics are needed complement a circular economy reduce resource depletion. Seaweeds have been known possess good film forming properties ideal bioplast...

The current study investigates capillary-fed boiling of water from porous sintered powder wicks used in emerging high-effective-conductivity vapor chamber heat spreaders intended for management of hot spots with heat fluxes exceeding 500 W cm . Characterization of 1 mm thick wicks composed of 100 lm sintered copper particles is performed in a test facility which replicates the capillary feeding...

The current study investigates capillary-fed boiling of water from porous sintered powder wicks used in emerging high-effective-conductivity vapor chamber heat spreaders intended for management of hot spots with heat fluxes exceeding 500 W cm -2 . Characterization of 1 mm-thick wicks composed of 100 μm sintered copper particles is performed in a test facility which replicates the capillary feed...

The use of organic–inorganic hybrid compounds containing tetraethoxysilane (TEOS) and hydroxyl-terminated polydimethylsiloxane (PDMS-OH) is one of the most promising approaches for using alkoxysilane-based formulations to improve the effectiveness of the consolidation of traditional silicate artifacts, such as ancient stone. Based on analysis of existing damaged potteries influenced by the crys...
