Sandwiched carbon nanotube film as strain sensor

Two types of carbon nanotube nanocomposite strain sensors were prepared by mixing carbon nanotubes with epoxy (nanocomposite sensor) and sandwiching a carbon nanotube film between two epoxy layers (sandwich sensor). The conductivity, response and sensitivity to static and dynamic mechanical strains in these sensors were investigated. The nanocomposite sensor with 2-3 wt.% carbon nanotube demonstrated high sensitivity to mechanical strain and environmental temperature, with gauge factors of 5-8. On the other hand, a linear relationship between conductivity and dynamic mechanical strain was observed in the sandwich sensor. The sandwich sensor was also not sensitive to temperature although its strain sensitivity (gauge factor of about 3) was lower as compared with the nanocomposite sensor. Both sensors have excellent response to static and dynamic strains, thereby having great potential for strain sensing applications.

From ethnocentrism to transculturalism : a film studies pedagogical journey

This study reviews the exploratory implementation of an ‘internationalising the curriculum’ policy in relation to a cultural studies unit within a Creative Industries Faculty at an Australian university. Charting certain pedagogical practices in the delivery of transnational film studies, this case study involves a critical, contextual examination of student feedback as well as current theories about transcultural curricula in general and film studies curricula in particular. The study shows that tertiary students can be provided with an extraordinarily rich range of differing, sometimes conflicting, but always engaging transcultural insights and understandings. It is further argued that transnational competencies may be developed and enabled through the innovative realisation of a type of ‘border crossing’ pedagogical model, largely by foregrounding transcultural ‘affective’ issues around social justice.

Film review : Citizen Murdoch?

It hasn’t been a good year for media barons. Actually, it’s not been a great century. In 2007 Baron Conrad Black was sent to jail in the US for embezzling his shareholders. Silvio Berlusconi’s grip on the Italian media hasn’t prevented a steady flow of allegations of sleaze and scandal since 2009, which have reduced him to a global laughing stock. And since July 2011, we have seen the dizzying fall of Rupert Murdoch and his son, James, from their positions of unquestioned (and unquestionable) authority at the helm of the world’s most powerful media empire.

Photocatalytic reduction of carbon dioxide to formic acid, formaldehyde, and methanol using dye-sensitized TiO2 film

A bifunctionalized TiO2 film containing a dye-sensitized zone and a catalysis zone is designed for visible-light photocatalytic reduction of CO2 to chemicals continuously. Charge separation can be accomplished with electron transferring to catalysis zone and positive charge transforming to anode. Highly efficient conversion of CO2 to formic acid, formaldehyde, and methanol is achieved through the transferring electrons on conduction bands (CB) of TiO2. Reduction of CO2 and O2 evolution take place in separated solutions on different catalysts. The separated solution carried out in this photo-reactor system can avoid CO2 reduction products being oxidized by anode. The yields of reduction products were enhanced remarkably by external electrical power. This study provides not only a new photocatalytic system but also a potential of renewable energy source via carbon dioxide.

Creativity is as important as literacy : making a film trailer responding to literature

The first part of the title is from Sir Ken Robinson (Robinson, 2009), the esteemed educator and champion of creativity in schools. Sometimes in the face of meeting the demands of time, timetabling, demanding administration tasks and teaching for high stakes testing accountability, we can find ourselves desperate for time to remember that English has always been one of the places in schools where creativity can flourish. English is a place for the play of the imagination. English teachers are the purveyors of narrative; the keepers and teachers of stories. The new Australian Curriculum: English, (Australian Curriculum and Assessment Reporting Authority (ACARA), 2012) asks us to be using ICT technologies in creative ways to tell those stories. The curriculum asks students to access texts receptively and to then speak about, write and create texts productively. There are so many interesting things to do with texts beyond word processing of print based resources. Responding to literature through media is always an alternative option to writing or simply speaking about it. In this paper my QUT pre-service student Chrystal Armitage describes how she made a mini story via a film trailer in response to a short story, ‘Turned’ (Gilman, 1987) in the unit, Literature in Secondary Teaching.

Policy measures for creating an integrated and brand-focused innovation system for film industries in shadow nations : an application to Australia's national film industry

Shadow nations face particular problems in constructing competitive film industries. Shadow nations refer to nations whose relative competitiveness suffers from easy product substitutability by products initiated, produced and distributed by powerful actors, such as media conglomerates located in Hollywood. The dominant literature has so far neglected the developing policy recommendations for dealing explicitly with the challenges of shadow nations. This paper aims to develop and apply a normative model for the development of film industries in shadow nations. The model integrates insights from innovation system studies and place branding. The developed model is applied to the Australian film industry as Australia represents a typical shadow nation within the film industry.

Melt textured Y123 bulk and thick film

YBa2Cu3O7-δ - 25mol%Y2BaCuO5 bars and thick films have been melt textured using a stationary furnace with a temperature gradient of 3 or 6°C/cm. Samples are heated above the peritectic reaction temperature and quenched to just above the solidification temperature and then slowly cooled below the solidification temperature. All bar shaped samples consist of 2-5 mm grains though the grain orientations strongly depend on the heat treatment conditions. The bar shows the maximum Jc of above 3,000 A/cm2, whereas the maximum Jc of 200 A/cm2 and Tczero of 88K are obtained for the thick film on (100) LaAlO3 single crystal.

Thin-film elemental analyses for precise characterization of minerals

The Analytical Electron Microscope (AEM), with which secondary X-ray emission from a thin (<150nm), electron-transparent material is measured, has rapidly become a versatile instrument for qualitative and quantitative elemental analyses of many materials, including minerals. With due regard for sources of error in experimental procedures, it is possible to obtain high spatial resolution (~20nm diameter) and precise elemental analyses (~3% to 5% relative) from many silicate minerals. In addition, by utilizing the orientational dependence of X-ray emission for certain multi-substituted crystal structures, site occupancies for individual elements within a unit cell can be determined though with lower spatial resolution. The relative ease with which many of these compositional data may be obtained depends in part on the nature of the sample, but, in general, is comparable to other solid state analytical techniques such as X-ray diffraction and electron microprobe analysis. However, the improvement in spatial resolution obtained with the AEM (up to two orders of magnitude in analysis diameter) significantly enhances interpretation of fine-grained assemblages in many terrestrial or extraterrestrial rocks.

Thin-film analyses of silicate standards at 200 kv : the effect of temperature on element loss

Preliminary data is presented on a detailed statistical analysis of k-factor determination for a single class of minerals (amphiboles) which contain a wide range of element concentrations. These amphiboles are homogeneous, contain few (if any) subsolidus microstructures and can be readily prepared for thin film analysis. In previous studies, element loss during the period of irradiation has been assumed negligible for the determination of k-factors. Since this phenomena may be significant for certain mineral systems, we also report on the effect of temperature on k-factor determination for various elements using small probe sizes (approx.20 nm).

Licensed to sell : product placement in the James Bond film series

As one of the longest running franchises in cinema history, and with its well-established use of product placements, the James Bond film series provides an ideal framework within which to measure and catalogue the number and types of products used within a particular timeframe. This case study will draw upon extensive content analysis of the James Bond film series in order to chart the evolution of product placement across the franchise's 50 year history.

The International Film and Television School in Cuba : for a stronger media culture in the global south

A little-known facet of Cuban internationalism is the Cuba shares in the education of young people who want to help build a stronger media culture that represents voices from the global South. Cuba was instrumental in the establishment and operation of the International Film and Television School at San Antonio de los Baños. The Cuban government provided the location and buildings for the school, and among the range of international media professionals who teach the students are selected Cuban professors from the Institute of the Arts, based n Havana. The International Film and Television School is supported by funding from Spain and other countries, and by the willingness of international media professionals to teach short courses for little more than an honorarium. Cuba used to provide full scholarships for student from the South to study a two-year course in film or television, but now charges fees for its three-year diploma course.

Explaining Pathe's global dominance in the pre-Hollywood film industry

For almost a decade before Hollywood existed, French firm Pathe towered over the early film industry with estimates of its share of all films sold around the world varying between 50-70%. This paper analyses Pathe’s rise to market leadership by applying a theoretical framework drawn from the business literature on causes of industry dominance, that provides insights into how firms acquire and maintain market dominance. This paper uses evidence presented by film historians to argue that Pathe “fits” the expected theoretical model of the dominant firm because it had a marketing orientation, used an effective quality- based competitive strategy and possessed the six critical strategic marketing capabilities that business research shows enable the best performing firms to consistently outperform rivals.

Triple Helix: Film Noir, Neo Noir and Los Angeles – imagining history and remembering the future in the most contemporary city
