How to Spell ‘Film’

In their performances and installation work, Sandra Gibson and Luis Recoder address the specificities of cinema by investigating the event of projection. Modifying film projectors by removing essential parts and subverting the protocols of projection, the artists foreground the basic elements of cinematic articulation. Focusing primarily on Light Spill (2005) and Reduction Print (2014) and comparing them to canonical contributions to structural film, the chapter argues that the object-based and performancebased trajectories in Gibson + Recoder’s work as two distinct strategies of circumscribing the media complex ‘film’ and the cultural technique of cinema. In doing so, they also provide a genuine way to re-negotiate the peculiarities of the cinema and contemporary exhibition spaces.

Study on Synergistic Corrosion Inhibition Effect between Calcium Lignosulfonate (CLS) and Inorganic Inhibitors on Q235 Carbon Steel in Alkaline Environment with Cl−

The synergistic corrosion inhibition effect between calcium lignosulfonate (CLS) and three kinds of inorganic inhibitors (Na2MoO4, Na2SnO3, and NaWO4) with various molar ratios on Q235 carbon steel in alkaline solution (pH 11.5) with 0.02 mol/L NaCl was investigated by cyclic potentiodynamic polarization, electrochemical impedance spectroscopy, linear polarization, scanning electron microscopy, and X-ray photoelectron spectroscopy. Molybdate and stannate in hybrid inhibitor could promote the passivation of steel and form a complex film, which could suppress the corrosion effectively. Moreover, the insoluble metal oxides in the complex film formed by three kinds of inorganic inhibitor could help the adsorption of CLS onto the steel surface. The CLS molecules could adsorb onto the steel surface and metal oxides to form an adsorption film to protect the steel from corrosion. A three-layer protection film formed by a hybrid inhibitor, including passivation film, deposition film, and adsorption film, would effectively inhibit the corrosion reactions on the steel surface. The CLS compound with molybdate with the ratio of 2:3 shows the best inhibition effect on both general corrosion and localized corrosion.

RELEASE OF α-TOCOPHEROL FROM CHITOSAN/PECTIN POLYELECTROLYTE COMPLEX FILM INTO FATTY FOOD SIMULANT FOR THE DESIGN OF ANTIOXIDANT ACTIVE FOOD PACKAGE

Lipid oxidation is one of the leading causes of the decline in food product quality. However, it might be overcome with active antioxidant packaging technologies, which is based on the incorporation of antioxidants to the packaging material. In this study, the polyelectrolyte complex (PEC) from chitosan (CS) and pectin (PE) was used as a packaging material and a-tocopherol (a-TOH) was used as an antioxidant to develop an antioxidant active packaging with the addition of Tween-80 to facilitate the incorporation of hydrophobic a-TOH into hydrophilic PEC CS/PE solution. This research showed that the composition of PEC chitosan/pectin, the concentration of Tween-80, and the concentration of a-TOH affected the releasing profile of a-TOH. The hydrophilicity of film increased with the increase of PE amount in PEC and the concentration of Tween–80. This improvement in the hydrophilicity also led to an increase in the release of a-TOH. The highest accumulative release of a-TOH was achieved when using a film with the highest initial concentration of incorporated a-TOH (C3), which was up to 98.49%. The result of the performed DPPH assay showed that the complex films exhibited high antioxidant activity up to 90.60%. The releasing profile of all films exhibited an initial burst effect followed by sustain release over 10 d. Therefore, this film can be promising as an antioxidant active package.
