Visible-light photoelectric performance and bending stability of flexible LaCoO3/Mica thin films

New energy sources such as solar energy have been developed and utilized due to the shortage of non-renewable energy, and photoelectric materials have attracted more attention, accordingly. Moreover, flexible optoelectronic devices are crucial in the fields of wearable artificial intelligence, portable energy, and smart medical care. At present, photoelectric devices based on traditional perovskite cobalt oxide rigid films have problems such as inability to bend and deformation, which limits their application environment. Here, natural mica with atomically flat surface, high thermal stability, high transparency and good mechanical flexibility was selected as the substrate for preparing a series of LaCoO3 flexible photoelectric films. These films exhibit excellent photoelectric properties and flexible properties. More importantly, the flexible film still has fast response speed and reproducible light response after 500 bending cycles. It reveals that all-inorganic perovskite LaCoO3 is a promising candidate for designing high-performance, flexible and wearable optoelectronic devices.

An investigation of cross-cultural gender-wise stereotypes in apologizing through film series

The present study examined gender-wise differences in the use of apology strategies employed by Persian and American English interlocutors in two popular Persian and American TV film-series. To this aim, 347 apology utterances across 600 min of both Persian and American TV film-series were selected for analysis. The apology utterances produced by males and females in the two film series were observed, classified, and coded based on the apology strategies taxonomy propounded by Eslami-Rasekh (2004) [59]. The acquired data were analyzed through descriptive statistics and Binomial tests to depict the frequency and type of apologies concerning female-female, female-male, male-female, and male-male interactions. The frequency of the males' apologies to the females and males suggested no statistically significant differences between the two communities. In addition, the findings manifested both similarities and differences in the realization and distribution of the apology speech act between males and females in the targeted cultures. For example, the apology strategies were more commonly used by the males than the females. Illocutionary Force Indicating Devices were the most frequent apology strategies employed by the Persian and American males in both languages. In the Persian film series, ‘Acceptance of responsibility’ and ‘Offer of repair’ were the other frequent apology strategies which differed significantly between the males and females. In the American film series, ‘Explanation’, ‘Acceptance of responsibility’, and ‘Refusing responsibility’ were the strategies found to be significantly different between the males and females. Generally, it was realized that males were more inclined to apologize in the examined film series despite the prevalent stereotype that women apologize more frequently than men.

Color-tunable fluorescence and ultralong organic room temperature phosphorescence from multicomponent copolymers

Materials with color-tunable photoluminescence (PL) have attracted dramatically increasing interest in recent years, especially the tuning of both fluorescence (FL) and ultra-long organic room temperature phosphorescence (UOP). Herein, a series of polymer films are successfully fabricated by in situ copolymerization of carbazole derivatives, lanthanide complex, and acrylamide (AM). With a long lifetime of 2.82 s and a high quantum yield of 21.40%, these copolymers exhibit not only color-tunable FL from violet-red to blue, but also multicolor UOP scope from blue to chartreuse when the excitation wavelength is changed. Moreover, a nearly-white phosphorescence can also be observed by adjusting the excitation wavelength. Multiple information patterns with color-tunable FL and UOP emissions are captured, exhibiting promising potential in the information encryption and anti-counterfeiting fields.

Confinement-Induced Isosymmetric Metal-Insulator Transition in Ultrathin Epitaxial V2O3 Films.

Dimensional confinement has shown to be an effective strategy to tune competing degrees of freedom in complex oxides. Here, we achieved atomic layered growth of trigonal vanadium sesquioxide (V2O3) by means of oxygen-assisted molecular beam epitaxy. This led to a series of high-quality epitaxial ultrathin V2O3 films down to unit cell thickness, enabling the study of the intrinsic electron correlations upon confinement. By electrical and optical measurements, we demonstrate a dimensional confinement-induced metal-insulator transition in these ultrathin films. We shed light on the Mott-Hubbard nature of this transition, revealing a vanishing quasiparticle weight as demonstrated by photoemission spectroscopy. Furthermore, we prove that dimensional confinement acts as an effective out-of-plane stress. This highlights the structural component of correlated oxides in a confined architecture, while opening an avenue to control both in-plane and out-of-plane lattice components by epitaxial strain and confinement, respectively.

Reading the Complexity of James Bond's National Identity on Film

Though frequently conceived of as an essentially neo-colonial figure, James Bond’s national identity in the Eon Productions film series is more complex. Rather than solely or even predominantly rooted in the imperial centre of England, Bond frequently emerges from peripheral and ambiguous spaces, whether the marginal within the United Kingdom – Scotland, Wales – or from former colonies, like Ireland or Australia. Of the six men who have portrayed Bond in the series, two are English (Roger Moore and Daniel Craig). The remainder portray Bond as ambiguously English-and-not. All of this comes to the forefront in 2012’s Skyfall, which directly addresses Bond’s national origins. The title refers to Bond’s homeplace: his family’s estate in Scotland. Bond is played here by Craig, an English actor, and the film avoids pinning down when he left Scotland, other than it being after his parents’ death. Because Skyfall has priest holes, this film also frames Bond as explicitly Catholic, further positioning him outside Britain’s imperial centre. Bond’s complex and peripheral national identity complicate postcolonial readings of the films. Homi K. Bhabha’s theory of mimicry illuminates Bond’s doubled existence: when members of a colonised society imitate and take on the culture of the colonisers, the effect is, as Lacan notes, “camouflage ... it is not a question of harmonizing with the background, but against a mottled background, of becoming mottled". In this context, Bond’s role “on her majesty’s secret service” raises questions of complicity, compliance, and the fraught, always incomplete disavowal of Otherness.

Visual Design of Chinese Animated Films Infused with Oriental Punk Aesthetics

In recent years, China's movie industry has been advancing, and movies based on ancient myths, which can combine cultural expression with technical expression, have become a hot topic for creation. Especially the ancient mythological novels such as "The Legend of Deification" and "Journey to the West" have become the source of creative ideas for movie adaptations, and Light Chaser Animation, as one of the most important forces in Chinese film production, has been exploring new possibilities for animation movies, inheriting and innovating traditional Chinese cultural elements. Light Chaser Animation, as one of the most important forces in Chinese film production, has been exploring new possibilities for animation films, inheriting and innovating traditional Chinese cultural elements, and has produced the famous "New Gods" series of films, which combines oriental elements and cultural characteristics, blends modernity and tradition, and forms an Oriental Punk style with Chinese characteristics. Oriental Punk not only shows the construction of modernity of Chinese traditional culture, but also the embodiment of cultural self-confidence, and at the same time presents the unique style and aesthetic value of Chinese culture to the world. This article analyzes the visual symbols, color design and action vocabulary of the film New Gods: Yang Jian, and points out a new direction for Chinese films to integrate traditional cultural elements and modern art technology in the creation of new mythological themes.

OA35 Amplifying young voices: the crucial role of young people living with rheumatic conditions in shaping information, advice and guidance

Abstract Background/Aims In 2021, Versus Arthritis launched Young Experts - a project to improve the quality and availability of information for young people aged 11-16 living with rheumatic conditions. The adolescent years are a distinct and formative period in life and a lack of youth accessible information had been identified. Methods Firstly, we completed an audit of current resources, research, and standards. This helped us identify best practice as well as gaps, including a lack of accessible developmentally appropriate resources and resources for families/professionals supporting young people. Secondly, we gathered insight through UK-wide surveys, focus groups and interviews with young people and parents. This helped us prioritise topics (school was selected as the initial priority topic) and identify key messages. Thirdly, we ran an online co-production project with over 30 young people. Creative activities were facilitated by youth workers and content creators over the course of several weeks on school based topics. Each week built on the last - building on themes, checking understanding, and prioritising. As themes emerged the team also engaged with healthcare professionals, health-based youth workers and education staff to explore key areas and professional perspectives. Results A wealth of insight has been gathered on supporting young people living with a rheumatic condition to thrive at school. The initial focus was on support development, but the insight has also had the added benefit of influencing campaigning and awareness raising work. Young people flagged a greater focus on creating films featuring young people and retaining hard copy resources, which fundamentally shaped the new resource development plan. Resources must be in accessible, engaging formats for all young people. Youth feedback led to a greater focus on resources that change their community and society (e.g. actions of school leaders and staff), alongside resources for young people. Prioritisation of messaging to include more content on ‘quality communication’, ‘school engagement’, ‘mental health and wellbeing’ and ‘relationships of trust between school and young people’. Impact on young participants included new friendships, self-management support, and a focus on youth social action to improve things for the next generation of young people. New resources included a series of films co-designed with young people, and school staff resources. Conclusion Engaging young people in shaping information should challenge assumptions on content, key messaging and approaches. To design without the involvement young people could lead to new resources that fail to lever their full potential - in both challenging communities to be more inclusive and/or meeting the needs of young people and their families. With thanks to the young people involved in the project and continuing to support this vital work. Disclosure L. Woolley: None. D. Bovey-Pilkington: None.

Exploring tribological characteristics of ZrN-MoSN composite films fabricated via RF magnetron sputtering: Insights from microstructure and performance analysis

Achieving the stringent demands of sustainable tribological industrial applications poses a significant challenge, particular in optimizing the self-lubricant performance of nitride-based films. This paper tackled this challenge by designing and depositing a series of ZrN-MoSN composite films with varying (Mo + S)/Zr ratios, employing RF magnetron sputtering, aimed to enhance the tribological properties through utilizing the high loading capacity of the ZrN matrix and the exceptional self-lubricating attributes of Mo-S-N additives. After conducting thorough investigations on the microstructure, and tribological properties, the results revealed that the dense columnar structured ZrN-MoSN composite films displayed a polycrystalline composition comprising fcc-ZrN and hcp-MoS2 phases, intertwined with amorphous phases of Mo(SN)x and MoS2(N2). (Mo + S)/Zr ratios below 1.08 exhibited a minor impact on the room temperature (RT) tribological properties, while higher ratios led to degradation on RT average friction coefficient (COF) and wear rate (WR). However, the synergistic effect of ZrN matrix and the tribo-phases of layered MoO3 and hard ZrO2 contributed to the significant enhanced 500 °C tribological properties, particularly with an optimized (Mo + S)/Zr ratio of 0.43.

Realization of ferroelectricity in sputtered Al1-xScxN films with a wide range of Sc content

The ferroelectric properties of wurtzite-structured Al1-xScxN thin films are affected simultaneously by the Sc concentration and in-plane stress state, however, the interaction between these two factors remains unclear. In this work, a series of Al1-xScxN films were deposited on (111) Si substrate by dual-target co-sputtering. X-ray diffraction analyses show the films with a wide range of Sc content (x= 0.05–0.50) have the (0002)-textured wurtzite structure and are in compressive stress state. Ferroelectricity in all the films is confirmed by polarization hysteresis loop measurements at room temperature, and the coercive field exhibits an interesting non-monotonic transition due to the competition between in-plane stress and Sc incorporation. The results provide insight into the wurtzite-structure stability and the nature of ferroelectricity for Al1-xScxN thin films.

Unveiling the growth mechanism of FeSeTe films by pulsed laser deposition technique

The superconductivity of FeSeTe films, deposited by the pulsed laser deposition (PLD), is extremely sensitive to the preparation conditions. Hence, it is necessary to study the growth mechanism and reveal the key factors affecting the superconductivity of FeSeTe films. Among all the preparation conditions, the substrate temperature ( Ts ) is one of the most critical one because it can alter the diffusion and nucleation of deposited atoms, as well as subsequent secondary volatilization. In this study, we prepared a series of FeSeTe films deposited on CaF2 substrates with Ts ranging from 25 ∘C to 700 ∘C. It is found that the growth mechanism of the FeSeTe films deposited at different Ts is determined by the competition between crystallization and volatilization, and the Ts can serve as an effective means to regulate the (Se+Te):Fe ratio of the FeSeTe films. The superconductivity of the FeSeTe films is co-modulated by the crystallinity and composition. In addition, the Ts can greatly affect the pinning mechanism of the FeSeTe films by introducing the fine nonstoichiometric particles, local chemical inhomogeneity and planar defects. This work facilitates the further performance improvement and practical applications of FeSeTe superconducting films, and is of reference for the FeSeTe film prepared by other deposition methods.

ABSTRACT This article explores the portrayal of contemporary Italian girlhood in the context of Italian media studies. It critically examines the emergence of a new media depiction of Italian high-school girls in the role of exchange students abroad. Given the widespread prevalence of this trend, which has received limited academic attention, the representations of these young travellers are examined across different media, offering insights into their dynamic agency as cultural intermediaries within Italian society. The inquiry draws from data from the AHRC research project A Girls’ Eye View. It analyses excerpts from project interviews and social media in order to shed light on the emergence of nomadic Italian girlhood as portrayed in TV series and on the TikTok platform. By exploring Italian girls’ nomadic aspirations, the study provides valuable insights into the dynamic relationship between travel, education, and the impact of social media on their lives.

Flexible Full-Inorganic Ultrathin Films with Stable Circularly Polarized Luminescence Covering the Visible to Near-Infrared Region.

Circularly polarized luminescence (CPL) materials hold significant value in various fields, including information storage, secure communication, three-dimensional displays, biological detection, and optoelectronic devices. Using the Langmuir-Schaeffer (LS) assembly technique, we successfully construct a series of large-area flexible optical ultrathin films. Impressively, the inorganic assembled ultrathin films exhibit excellent CPL optical activity covering the visible to near-infrared (NIR) region, with the luminescence asymmetry factor glum ranging from 0.59 to 0.72. Moreover, such ultrathin films also display outstanding mechanical flexibility, the optical activity of which even after 240 bending cycles shows almost no difference compared to the unbent samples. Owing to the ultra-broadband optical activity and ultra-stable optical activity of such full-inorganic assembled materials on flexible substrates, coupled with their excellent processability and outstanding mechanical flexibility, we anticipate they will find use in many fields such as communication technology and flexible optoelectronics.

Improvements of multifunctional spintronic and optoelectronic applications of nanostructured Eu-doped ZnS thin films through magnetic and linear, nonlinear optical investigations

This study describes the spintronic and optoelectronic improvements upon Eu substitution in Zn atomic site of the nanostructure ZnS thin films. The electron beam deposition technique has been used to deposit a series of Zn1-xEuxS thin films on a glass substrate with different Eu dopants (x = 0, 0.01, 0.03, 0.05, and 0.08). The nanostructure nature of the Eu-doped ZnS thin film has been confirmed from structural and morphology studies performed by the X-ray diffraction (XRD) and atomic force microscope (AFM) measurements. XRD investigations further show a hexagonal-type structure with no detectable extra phases with the lattice parameter c increasing, while a decrease linearly with increasing Eu-dopant in the ZnS hosted lattice. The microstructures analysis reveals a reduction in the mean crystallite size and increasing in the lattice strain of the films with rising Eu doping. The Fourier transform infrared spectra display the existence of chemical bonds in the thin films whereas photoluminescence reveals near-band edge emission. The linear optical parameters were obtained from the analysis of the transmission data measured by the spectrophotometer technique. The results reveal that the band gap energy (EgOpt) reduces by raising ohe Eu doping ratio, which is ascribed to the structural deformation (strain and/or defects) confirmed from structural analysis, density of localized states and PL measurements. The index of refraction n was calculated using the Swanepoel method. The values were found to increase as the level of Eu doping grows, which is associated with the rise in polarizability. Wemple and DiDomenico's (WDD) model was utilized to compute the dispersive and oscillator energies (Eo, and Ed), the nonlinear absorption coefficient βc, nonlinear refractive index n2, and nonlinear optical susceptibility χ3. The results demonstrate that the adjustability of EgOpt , Eo, and Ed of ZnS: Eu films is conducted to improve the nonlinear optical characteristics, providing it well-suited for optoelectronic device implementations. On the other hand, ZnS doped with Eu film displays inherent ferromagnetic properties at room temperature, as evidenced by the results of the magnetic investigation. This finding could be attributed to the presence of sulphur defects (vacancies), as supported by photoluminescence (PL) measurements, which lead to the creation of the bound magnetic polaron. These discoveries indicate the potential of utilizing Eu-doped ZnS film in the effective development of spintronic devices.

Acting and Dancing during the COVID-19 Pandemic as Art Therapy for the Rehabilitation of Children with Behavioural Disorders Living in Socially Disadvantaged Environments.

Art therapy is employed in numerous ways in rehabilitation. This study focuses on an art and movement therapy project carried out during the COVID-19 pandemic. Acting and dancing methods were adapted to produce a short musical film series for ten children from disadvantaged social backgrounds displaying nonorganic behavioural disorders. The aim was to acquire novel ways of expression on the part of the participants to release painful emotions in a safe setting using the method of catharsis through acting and dancing, triggering relaxation as a physiological response and improving their attitude. This study retrospectively analyses the changes in the children's behaviour and their active participation in the project through quantitative and qualitative research. The children improved their attention and self-esteem, their behaviour became less aggressive and impulsive, and half showed increased empathy. The active participation rate during the project was 82%.

Preparation and Properties of Low-Dielectric Polyimide Films Containing Tert-Butyl.

The design of high-performance polyimide (PI) films and understanding the relationship of the structure-dielectric property are of great significance in the field of the microelectronics industry, but are challenging. Herein, we describe the first work to construct a series of novel tert-butyl PI films (denoted as PI-1, PI-2, PI-3, and PI-4) based on a low-temperature polymerization strategy, which employed tetracarboxylic dianhydride (pyromellitic anhydride, 3,3',4,4'-biphenyl tetracarboxylic anhydride, 4,4'-diphenyl ether dianhydride, and 3,3',4,4'-benzophenone tetracarboxylic anhydride) and 4,4'-diamino-3,5-ditert butyl biphenyl ether as monomers. The results indicate that introducing tert-butyl branches in the main chain of PIs can enhance the free volume of the molecular chain and reduce the interaction between molecular chains of PI, resulting in a low dielectric constant. Particularly, the optimized PI-4 exhibits an excellent comprehensive performance with a high (5) wt% loss temperature (454 °C), tensile strength (117.40 MPa), and maximum hydrophobic angle (80.16°), and a low dielectric constant (2.90), which outperforms most of the results reported to date.

Enhanced Electro‐Optic Coefficients in Single‐Crystalline BaTiO3 Thin Films Enabled by Domain Alignment

AbstractIn silicon photonics, BaTiO3 (BTO) emerges as a promising electro‐optic (EO) integrated material due to its excellent EO modulation capabilities. Nevertheless, the EO response of multi‐domain BTO thin films tends to be lower than that of bulk materials. BTO thin films are fabricated with strong EO responses utilizing the pulsed laser deposition technique. Considering the importance of the SrTiO3 (STO) buffer layer, a series of epitaxial BTO thin films are deposited on STO substrates with engineered domain alignment. Given the contribution of domain variants in BTO thin films to their EO response, specific electrode patterns are designed to enhance their performance. An effective Pockels coefficient of 286 pm V−1 is determined for the BTO thin film via the transmission geometry method, which surpasses recent reports. Through domain engineering in the BTO thin film, the remarkable enhancement in the EO response arising from in‐plane polarization (a‐axis) characteristics is confirmed. Simultaneously, utilizing the Second Harmonic Generation (SHG) optical probe, deep exploration into the domain dynamics within BTO thin films is conducted. These findings provide insights into the contribution of domain variants to the EO response and shed light on further developing silicon‐based heterogeneously integrated devices.

Layer‐By‐Layer Chiral Induction of Fluorene‐Based Metal–Organic Framework Films for Circularly Polarized Luminescence Sensing of Enantiomers

AbstractDeveloping films of chiral metal–organic frameworks (MOFs) with high circular polarization luminescence (CPL) is facing a great challenge for chiral sensing applications. Herein, a layer‐by‐layer chiral induction method is first reported to prepare enantiopure MOF films for CPL sensing. By layer‐by‐layer induction with the chiral inductor camphorsulfonic acid, fluorene‐based chiral MOF D/L‐ZnHF‐SO2 film (HF‐SO2 = 3,7‐Dibenzothiophenedicarboxylate, 5,5‐dioxide) with preferential growth orientation and homogeneous surface are prepared, which shows strong chiral feature and CPL with higher asymmetry factor of ±0.073. In addition, by mixed ligand approach, the isostructural fluorene ligand 9‐fluororenone‐2,7‐dicarboxylate is chosen to replace part of HF‐SO2 for preparing a series of chiral MOF films with tunable CPL emission. Furthermore, the prepared chiral MOF films with strong CPL performance are further utilized for enantiomers sensing. The CPL changes consisted with enantioselective adsorption results showed that D/L‐ZnHF‐SO2 film has good discrimination against chiral R/S‐phenylethylamine enantiomers, first reporting chiral MOF‐based candidates for the application in CPL sensing of enantiomers. This work provides a facile and effective approach for preparing chiral MOF films materials with high and tunable CPL performance, and also gives a new way to achieve CPL sensing of chiral enantiomers.

Electrodeposited CrMnFeCoNi Oxy-carbide film and effect of selective dissolution of Cr on oxygen evolution reaction

High entropy compounds were proven to exhibit excellent catalytic activity. Here, a series of amorphous CrMnFeCoNi Oxy-carbide films were successfully synthesized by one-step electrodeposition. As demonstrated, the film presented superior electrocatalytic activity for oxygen evolution reaction (OER) with an overpotential of 295 mV at a current density of 10 mA/cm2. Uniquely, selective dissolution of Chromium (Cr) was observed, which increased the catalytic activity and showed high stability under a large current density of up to 400 mA/cm2. Cr dissolution not only increased the surface area but also improved the conductivity due to newly formed metal-metal bonding, promoting electron transfer and improving OER performance. As revealed by density functional theory (DFT) calculations, Cr-dissolution mediates the bonding of OER intermediates over surface active sites and ultimately reduces OER overpotential. The one-step electrodeposition method and the micro-dissolution mechanism provided a potential way to design and prepare high entropy compound electrodes, aiming to achieve efficient water electrolysis.

Development of multilayer films based on PLA/PBAT and sodium alginate for active packaging

AbstractIn this study, polylactic acid (PLA) and polyadipic acid/butylene terephthalate (PBAT) blend polymer were used as matrix to prepare PLA/PBAT substrate film by twin‐screw extruder. A series of multilayer films were prepared by starch‐based adhesive by loading 1% chitosan (CS), 1% zinc oxide nanoparticles (ZnONPs) or 1% silver nanoparticles (AgNPs) with sodium alginate (SA) as three different coatings. Compared with PLA/PBAT, the combination of adhesive and SA‐based antibacterial coating significantly improved the water vapor barrier, oxygen barrier and mechanical properties of the film, regardless of the type of antibacterial agent. The water vapor transmission of SA‐based AgNPs coating film decreased from the original 5.77 × 10−14 to 3.41 × 10−14 g·cm·cm−2·Pa−1·s−1. The oxygen permeability of SA‐based chitosan coating decreased from the original 74.35 × 10−14 to 6.40 × 10−14 cm3·cm·cm−2·Pa−1·s−1. The tensile strength of the SA‐based AgNPs coating film increased from the original 264.79 to 286.22 MPa. The film is yellow and has good ultraviolet absorption capacity. Membranes doped with CS, ZnONPs or AgNPs inhibited the growth of Escherichia coli and Staphylococcus aureus. Among them, chitosan doped membrane has weak antibacterial activity, AgNPs doped membrane has the best antibacterial activity against E. coli and S. aureus, and has potential application prospects in active packaging.
