Background: Edible film is a food packaging that can be eaten directly and have protection function of outside contamination. The purpose of this research is to know how about the effect of using a glycerol plasticizer to film whey-konjac edible films that enriched with clove essential oil. Methods: A completely randomized design was used by different clove essential oil including P10, 0% clov...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

We have investigated the fabrication of α-Cr2O3(0001) thin film on a Au(111) surface and the effect of the antiferromagnetic feature of α-Cr2O3(0001) on the magnetic properties of ultrathin Co film on α-Cr2O3(0001). Highly oriented α-Cr2O3(0001) thin film is fabricated by oxidizing Cr(110) thin film grown on a Au(111) surface. Upon the oxidization of threefold symmetric Cr(110) thin film, the α...

ilicon Carbonitride (SiCN) is a novel polymer derived ceramic material, which is not only mechanically, chemically and thermally robust, but also possesses functional properties. These properties yields SiCN as an excellent choice for sensor applications in high temperatures with harsh chemical conditions. The principal objective of the research is to develop the underlying materials science fo...

introduction:packaging is an important factor in food industry and is dominated by petroleum-derived polymers. therefore, the amount of research involving the production and characterization of biodegradable films has increased substantially, mainly due to interest in minimizing the ecological impact caused by the use of synthetic packaging materials. several biopolymers have been exploited to ...

Recently, it has been shown that the size quantization of itinerant electrons in an ultra thin metal film plays an important role in the early formation stages and kinetic stabiliy of thin films. This Quantum Size Effect(QSE) also brings about a lot of new interesting physical and chemical properties of thin film. In this paper, I will give a brief introduction to the mechanism of QSE and talk ...

High voltage gradient ZnO-based thick film varistors were fabricated by low-temperature sintering. The effect of sintering temperature on electrical properties of thick film varistors was investigated. The voltage gradient of thick film varistors increased significantly to 3159.4 V/mm after sintering at 725°C for 30 min. The small average grain size with good grain boundaries was the origin for...

The decision criteria for the physical appearance of pharmaceutical products are subjective and qualitative means of evaluation that are based entirely on human interpretation. In this study, we have developed a comprehensive method for the quantitative analysis of the physical appearance of film coated tablets. Three different kinds of film coated tablets with considerable differences in their...

The effect of adding a hydrocolloid on the structural, mechanical and barrier properties of zein-based blend films is evaluated. Zein-oleic acid blend film with added xanthan gum (Z-OA-XG) showed higher water solubility (13.09%) and opacity (8.49 AU/mm) than zein-oleic acid (Z-OA) film (10.80% and 5.19 AU/mm, respectively). Furthermore, Z-OA film had greater flexibility with lower Young's Modul...

Residual stress in optical thin film coatings can cause adhesion failures, cracking, buckling, and bending of the substrates. The stress in the coating depends on the materials used, deposition process, and the design. The bulk properties of the coating materials and the substrate such as thermal coefficient of expansion, Young’s Modulus, Poisson’s Ratio, etc., are basic parameters to be consid...
