We investigated the preparation of well-dispersed core-shell ceria-poly(vinylpyrrolidone) (PVP) nanoparticles with an average particle size of around 20 nm which were used to produce a hybrid film with a polymer coating of dipentaerythritol hexaacrylate (DPHA). We obtained good dispersion of the nanoparticles in a mixed solvent of 48% 1-methoxy-2-propanol (MP), 32% 3-methoxy-3-methyl-1-butanol ...

Poultry meat is one of the perishable foods. The growth of pathogenic microorganisms may occur in chicken meat during refrigerated storage. Microbial growth causes serious hazard in food safety consumer. The aim of this study was to compare antimicrobial properties of Thymus vulgaris (TEO) and Zataria multiflora essential oil (ZEO) and the effect of carboxymethyl cellulose (CMC) films containin...

The aim of this study was to measure the gas permeability of edible films using a homemade experimental apparatus and to determine the respiration rate of tomatoes (L. esculentun var. Cerasiforme) without (NC) and with (CC) edible coating at different temperatures. Permeability was determined using an experimental device according to the ASTM D1434 method and the apparatus was validated using p...

We experimentally examine the primary rainbow created by the illumination of a coated cylinder. We present a simple technique for varying the coating thickness over a wide range of values, and we see evidence for two different scattering regimes. In one, where the coating thickness is large, twin rainbows are produced. In the second, where the coating is thin enough to act as a thin film, a sin...

As an alternative to the traditional indium tin oxide transparent electrode, solution-processed metal nanowire thin film has been a promising candidate due to its flexibility. However, high contact resistance between the nanowires remains a major challenge to improve the performance. Here, we have investigated a one-step process of coating and welding of nanowires on flexible film. An electric ...

The critical parameters for the structural stability of physical vapor deposited TiN film on (112̄0) sapphire were investigated by analyzing the adhesion strength and failure mechanism through in situ observations of the fracture sequence during scratch tests and static normal indentation. TiN was deposited by arc ion plating on (112̄0) sapphire, and the thickness of the TiN film was controlled t...

it is possible to develop new biodegradable active packaging by coating biopolymers on paper-based packaging material and also incorporating proper antimicrobial agents into coating structure. in this study bacterial contamination of two commercial cardboard were evaluated.in order to manufacture an appropriate antibacterial packaging material, coating of chitosan-poly vinyl alcohol blends with...

Diamond-like carbon (DLC), a thin amorphous carbon film, has many uses in tribological systems. Exploiting alternative substrates and interlayers can enable control of the hardness and modulus of the multi-layer system and improve wear or friction properties. We utilise XPS and AFM to examine DLC concurrently coated on an epoxy interlayer and a steel substrate by plasma enhanced chemical vapour...

We report on the effect of dopant concentration and substrate temperature on the electrical, optical and structural propertie of In-doped ZnO thin films via sol-gel method using spin coating technique to tackle the problem of high instrumental costs for film deposition. In particular, the effect of In dopant concentration will study at wide range (from 1% up to 10%) by using spin coating techni...

Phase separated films with controlled porosity were made from ethyl cellulose (EC) and 30% w/w hydroxypropyl cellulose (HPC). The molecular weight of EC can be used to modify the mass transfer rate through coatings by effects on microstructure of the film. Processing conditions are, however, affected by the solution rheology, which could influence the film quality when using different molecular...
