Abstract:
The functional properties of biopolymer-based film packaging materials are susceptible to external storage conditions. The effects of different storage temperature, relative humidity (RH) and duration on the apparent form, barrier properties, mechanical properties and microstructure of corn–wheat starch/zein bilayer films were studied. From 0 to 150 days, storage temperature and RH, but not storage time, affected the appearance and colour of the bilayer films. The increase in haze of the bilayer films stored at 25°C was much greater than that at low temperatures. With increased storage time, the moisture content first increased and then decreased, while the water resistance and oxygen barrier properties of the bilayer films worsened. After 150 days, the bilayer film stored at 25°C with 54% RH had better water resistance properties. The oxygen barrier properties of the bilayer film stored at 25°C with 43% RH were preferable to those of other groups because the peroxide value of vegetable oil packed in the former bilayer film was the lowest. The tensile strength of bilayer films stored at 25°C with RH of 43, 54 and 65% decreased, but was still better than those stored at low temperatures (−17°C, 4°C), which were tough due to their high elongation at break. Scanning electron microscopy results showed tight bonds between the bilayer films, and the network structure inside the films disappeared and reappeared during storage. The cross-sectional compactness changed, and there was no film separation after 150 days.

Abstract:
Egg whites of salted duck eggs are normally discarded in the separation of egg yolks. Most of the nutritional values of normal duck eggs are still retained in the egg whites of salted duck eggs. To make use of such egg whites, it is necessary to process the egg whites into a protein-rich powder, which can be used as a food processing material. Nevertheless, long-term storage of the egg white powder is challenging because this powder can easily absorb moisture, resulting in physical deteriorations (e.g: colour change), chemical alternation (e.g., protein and lipid degradation), and biological contamination (e.g., growth of yeasts and molds that produce toxic compounds). A study was conducted to test different types of packaging materials includingone-layered Polyethylene (PE) film, two-layered PE film, and three-layered films (PE, AL-Foil, BOPP/PE, Al/PE, BOPP/Al/PE, PET/Al/PE). The result shows that the most suitable packaging material for the protein-rich powder produced from egg whites of salted duck egg was two-layered AI/PE film. The quality of the product stored in AI/PE film package remained nearly unchanged in 12 months, which proved safe to be used as food processing material.

Abstract:
PDLC films are very useful materials and can apply in flexible displays, intelligent switchable windows, information storage and adaptive optical devices. In this paper we focus on its color display characteristic in reflective display and firstly we fabricated PDLC films by polymerization induced phase separation method and measured its transmissivity and spectral reflection curves of the printing ink layer and PDLC covered color by X-Rite DTP41 Spectrophotometer. From the result, it demonstrates that PDLC films show different optical transmission properties in long and short wavelength.

Abstract:
Corn fiber from the corn starch industry is a by-product produced in large quantity that is mainly used in animal feed formulations, though it is still rich in valuable components, such as arabinoxylans, with proven film-forming ability. During arabinoxylans’ recovery under alkaline extraction, a dark-colored biopolymer fraction is obtained. In this work, a purified arabinoxylan extract from corn fiber with an intense brownish color was decolorized using hydrogen peroxide as the decolorizing agent. Biodegradable films prepared by casting the decolorized extract exhibited a light-yellow color, considered more appealing, envisaging their application in food packaging. Films were prepared with glycerol as plasticizer and citric acid as cross-linker. Although the cross-linking reaction was not effective, films presented antioxidant activity, a water vapor permeability similar to that of non-decolorized films, and other polysaccharides’ and mechanical properties that enable their application as packaging materials of low-water-content food products.

Abstract:
As an important functional material in food industry, intelligent packaging films can bring great convenience for consumers in the field of food preservation and freshness detection. Herein, we fabricated pH-sensing films employing hydroxypropyl guar (HPG), 1-butyl-3-methylimidazolium chloride (BmimCl), and anthocyanin (Anth). Besides, the effects of adding cellulose nanocrystals (CNC) into the composite films upon the films’ structures and physicochemical properties are elucidated. The addition of CNC promoted more compact film structures. Moreover, CNC dramatically improved several properties of the pH-sensing films, including the distinguishability of their color changes, sensitivity to pH, permeability to oxygen and water vapor, solvent resistance, durability, and low-temperature resistance. These results expand the application range of pH-sensing films containing CNC in the fields of food freshness detection and intelligent packaging.

Abstract:
The main aim of the study was to prepare the edible films based on carrageenan/chitosan and incorporate them into the following matrices: the natural extracts of Clitoria ternatea, Brassica oleracea, and Ipomea batatas. The films were characterized by TPC (total polyphenols content), antioxidant activity, and textural properties. Experimentally produced films were added in the packaging of freshly cut apple pieces, and the apple pieces were dipped into the films produced from carrageenan and chitosan. The appearance of the samples was monitored, as were antioxidant activity and total polyphenol content. The intelligent properties of films were evaluated too. The polymer type used for the preparation had the highest impact on the prepared films, and CHLCZ (red cabbage extract—Brassica oleracea) featured the best antioxidant activity. The intelligent properties were slightly confirmed in samples with the addition of red cabbage. The main finding was that the coating of fresh-cut apples emphasized the possibility to use a carrageenan matrix with the addition of extracts. The samples immersed in this coating type showed higher antioxidant activity as well as a superior color when compared to that of chitosan coated apple samples.

Abstract:
This thesis analyses the effect of the personal history of Arthur and Corinne Cantrill, two Australian independent filmmakers, on their style of filmmaking. It analyses their representation of film-form experimentation within national Australian art in a range of independent film works. It reflects on their cultural relation to the general history of independent filmmaking in Australia, America and Europe. It studies the circumstances tat resulted in the appearance of the Cantrills' experimental film and their relation to international art theories and film experimentation. This thesis will examine how the Cantrills' film works, which were often critical of conventional filmmaking styles, and their critical writing, statements and promotion of their independent and experimental film work contributed significantly to theoretical discussion and argument about the physical nature of film within Australia. This examination is explored through asking and answering the central question: The work of Aurtheur and Corinne Cantrell is theoretically drawn from a tradition of European arts and visually drawn from Australian landscape and urban culture; can their work be identified and undertood as Australian art?

Abstract:
In this study, red, green, and blue light-emitting diodes (LED) are adopted as the light source to illuminate sequentially a two-dimensional soap film channel flow. Triple-exposure particle image is recorded on the same image frame by a 3-ccd color camera. Since the particles illuminated by the R, G, B LED will only be recorded on the R, G, B ccd-chip of the digital camera, three sequential exposure, R, G, B particle images can be obtained from separating the triple-exposure particle image. Two sequential velocity fields can be determined from the correlation analysis of the R-G and G-B sequential particle images. Time derivative of the velocity fields, and hence the evolution of the unsteady flow or the characteristics of turbulent flows can be analyzed from the two velocity fields determined. The color PIV method incorporated with the LED light has proven to be a cheap, safe, and powerful tool for the full-field flow measurements. Results of the flow past circular cylinder in the confined soap film channel flow are presented.
