Electrical and UV-sensing performance of N-doped-Ba(Ti,Zr,Mo,Hf,Ta)O3-dielectric and ZnSnO-channel-based flexible thin-film transistors

Flexible thin-film transistors (TFTs) based on N-doped Ba(Ti,Zr,Mo,Hf,Ta)O3 dielectric and ZnSnO channel show high electrical and UV-sensing performance. The optimal N-doped Ba(Ti,Zr,Mo,Hf,Ta)O3 compositions with low equivalent oxide thicknesses (≈2 nm) and high-entropy (configurational entropy ≈ 1.59 R) are efficiently determined from a wide composition space (library). The film library is patterned to 450 metal–insulator-metal stacks, revealing dielectric constants ≈ 262–322 and loss (tan δ) ≈ 0.01–0.30 for the N-doped Ba(Ti,Zr,Mo,Hf,Ta)O3 at 1 kHz. The library is further integrated to 63 TFTs, and the promising ones exhibit the remarkable parameters: current on/off ratio of 108, threshold voltage (VT) of 0.02 V, saturation field-effect mobility of ≈76 cm2⋅V−1⋅s−1, and subthreshold swing of 0.062 V dec−1. The devices also exhibit desirable long-term stability for up to five months and perform reliably with small or negligible changes in VT and drain-source current under various gate-bias stress and temperature conditions. Furthermore, the TFT-based ultraviolet (253 nm) detector demonstrates impressive sensitivity (≈ 2 × 106) and responsibility (≈ 1171.9 A W−1). There is no substantial degradation in electrical or sensing characteristics under various levels of deformation. Charge transport in constructed energy band diagrams is used to elucidate the observed remarkable performance.

Spanish tourist industry during the Franco’s regime through the touristic cinema (1951-1977)

Mass tourism in Spain became one of the most prosperous economic sectors in the mid-twentieth century, collaborating in the process of convergence with Europe, using the seductive power of the media, especially the cinema. A quantitative and (to a lesser extent) qualitative analysis methodology was followed. After reviewing the academic literature, the records of the National Film Library were consulted, selecting 87 films of tourist content and of national production, during the period of operation of the Ministry of Information and Tourism (1951-1977). The results have made it possible to identify the tourist segments, the cinematographic genres, the type of tourists, national or foreign, as well as the heritage elements and the services present in the tourist product of the time, visualizing the scenarios where the plots of the films are developed. The cinematography allows showing the elements that constitute the economic tourism model of Franco’s Spain, focused on towns on the Mediterranean coast, especially on the Costa del Sol. The research translates the antecedents of tourism marketing, using cinema as a means of communication that recognizes the economic transformation of Spanish society and the new image of Spain to be projected abroad.

Harnessing Compositional Gradients to Elucidate Phase Behaviors toward High Performance Polymer Semiconductor Blends.

Polymer semiconductor/insulator blends offer a promising avenue to achieve desired mechanical properties, environmental stability, and high device performance in organic field-effect transistors. A comprehensive understanding of process-structure-property relationships necessitates a thorough exploration of the composition space to identify transitions in performance, morphology, and phase behavior. Hence, this study employs a high-throughput gradient thin film library, enabling rapid and continuous screening of composition-morphology-device performance relationships in conjugated polymer blends. Applied to a donor-acceptor copolymer blend, this technique efficiently surveys a broad composition range, capturing trends in device performance across the gradient. Furthermore, characterizing the gradient library using microscopy and depth profiling techniques pinpointed composition-dependent transitions in morphology. To validate the results and gain deeper insights, uniform-composition experiments were conducted on select compositions within and outside the gradient range. Depth profiling experiments on the constant composition films unveil the presence of the semiconducting polymer at the air interface, with apparent enrichment of the semiconductor at the substrate interface at low ratios of the semiconducting component, transitioning to a more even distribution within the bulk of the film at higher ratios. The generalizability of the gradient approach was further confirmed by its application to a homopolymer under different solution processing conditions.

Glass and nanocrystalline phase formation in CuZrAg alloys: Insights from combinatorial thin film libraries studied by mapping synchrotron X-ray diffraction

We report detailed diffraction peak analysis and parameters indicative of the transition between fully amorphous microstructures and nanocrystal formation in sputter deposited thin film metallic glasses. Specifically, we fabricated ternary CuZrAg alloy films (2µm thickness) with a large compositional gradient on flexible, X-ray transparent polymer substrates in high vacuum conditions. The combinatorial libraries were subjected to point-by-point structural (XRD synchrotron radiation) and chemical (X-ray fluorescence spectroscopy) analysis, characterizing roughly 172 alloys. A strong correlation was found between peak symmetry and width, and early stages of crystalline phase formation. These nanocrystals are difficult to detect from the evolution of the peak position. In view of current literature, our data questions the recently claimed universality of the peak width as indicator of high glass forming ability. The addition of Ag significantly improves the poor glass formation of binary CuZr (36 alloys) under identical deposition conditions, as fully amorphous alloys are found for the majority of the investigated composition space. A thorough understanding of the microstructure of CuZrAg alloys on flexible substrates is highly relevant in view of favourable antibacterial properties and potential application as coatings for biomedical surfaces.

Combinatorial Property Mapping of Titanium‐Zirconium Thin Film Libraries as Screening for Medical Material Candidates

By employing a co‐sputtering technique, combinatorial thin film libraries in the Ti–Zr system are produced. The libraries have a compositional spread ranging from 40 to 70 at% Ti. The confocal geometry of the sputtering system is maintained for the production of all thin films. The microstructural and crystallographic properties are elucidated by energy dispersive X‐ray spectroscopy (EDX), X‐ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. Furthermore, contact angle measurements and nanoindentations are performed to map the wettability, hardness, and elastic modulus of the alloy system. The electrochemical properties, i.e., the oxide film formation factor and the relative permittivity of anodically grown oxides on the parent metal alloys are determined. The measurements are performed in phosphate‐buffered saline in order to best simulate a biological environment. A linear shift in the properties is observed along the compositional gradient for the EDX, XRD, and SEM analysis. For all other sets of measurements deviations from the linear behavior, are observed around the 60 at% Ti concentrations. This coincides with the formation of a congruent alloy in bulk material. The observed changes however, deviated also from expectations for bulk alloys. The implications and potential for those alloys as implant material are discussed in the following.

Characterization of lithium phosphorus oxide thin film libraries by laser-induced breakdown spectroscopy imaging: A step towards high-throughput quantitative analyses

Elemental analysis is a challenge for the development of High Throughput Experimentation (HTE) on thin film materials, and an even greater one when it comes to screening lithium-containing battery materials. In this regard, Laser-Induced Breakdown Spectroscopy has been evaluated here for the quantitative analysis of lithium in libraries of Li2.3PO3.65 amorphous solid electrolyte films. The LIBS analysis of multiple samples with the same composition, but with thicknesses ranging from 50 to 700 nm, has revealed a linear trend in the intensity ratio of the Li I 610.35 nm and P I 214.91 nm emission lines, opening the way to rapid quantitative analysis of material libraries. The sensitivity of the technique finally allowed the detection of the Li I 670.79 nm emission line for film thicknesses down to 4 nm, corresponding to 0.2% of the ablated volume, or about 0.15 pg of Li.

The film comedies of Leonid Gaidai: student works and the formation of a style

ABSTRACT This article studies the early stage of the career of the well-known Soviet and Russian comedy filmmaker Leonid Gaidai, notably the training period at the All-Union Institute of Cinema (VGIK), on the basis of hitherto unknown archival sources. During these student years, many important stylistic lines of Gaidai’s comedy films were established: his interest in the synthesis of satire, sharp social criticism, trick comedy and eccentricity that would become well known to audiences. Firstly, new archival materials include the theoretical parts of the diploma works from the cinematographers’ faculty of Vladimir Boganov and Vadim Yusov at VGIK (hitherto unknown), and the film Darlings-Friends. Secondly, the short film and Gaidai’s coursework Darlings-Friends (1954), discovered by the film historian Sergei Kapterev at VGIK’s film library. Thirdly, the theoretical part of Gaidai’s dissertation (hitherto not known to researchers), who worked as probationer-assistant director and actor on the musical comedy Lyana by Boris Barnet. In this text, Gaidai for the first time formulates a number of principles for the creation of a comedy film and determines some important lines of his style.

La Filmoteca Canaria: memoria visual de las islas (2005-2023)

"We have tried to elaborate a starting inventory of the Canary Island Cinematheque activities over the last twenty years in relation with safeguarding audiovisual heritage of the Archipelago. We also deepen the functioning of the institution, pointing out some of its faults and identifying their successes and deficiencies. We had the opportunity to study the relationship between this film library and other cultural centers, the publication of books related to Canary Islands Cinema and the recovery of audiovisual materials, likewise donations and the creation of a film archive. Lastly, we have addressed our discussion to the future of digital cinema."

High-Throughput Study of Amorphous Stability and Optical Properties of Superlattice-Like Ge-Sb-Te Thin Films.

A high-throughput ion beam sputtering system is used to synthesize compositional gradient superlattice-like (SLL) thin film libraries of Ge-Sb-Te alloys over the entire phase diagram. The optical properties and structural evolution of the Ge-Sb-Te combinatorial SLL thin film are investigated. A systematic screening over the annealing temperature, annealing time, and modulation period has elucidated the critical factors that affect the stability of the metastable phase and optical properties. It is found that amorphous stability and optical constant are highly dependent on the modulation period and chemical composition of the thin film. This data-driven approach offers new perspectives for accelerating the development of new materials with excellent optical and amorphous stability and for exploring their mechanisms, by greatly expanding the dataset of Ge-Sb-Te alloys with SLL structures through high-throughput experiments.

Rational Design, Synthesis, and Structure-Property Relationship Studies of a Library of Thermoplastic Polyurethane Films as an Effective and Scalable Encapsulation Material for Perovskite Solar Cells.

Hybrid organic-inorganic metal halide perovskite solar cell (PSC) technology is experiencing rapid growth due to its simple solution chemistry, high power conversion efficiency (PCE), and potential for low-cost mass production. Nevertheless, the primary obstacle preventing the upscaling and widespread outdoor deployment of PSC technology is the poor long-term device stability, which stems from the inherent instability of perovskite materials in the presence of oxygen and moisture. To address this issue, in this work, we have synthesized a series of thermoplastic polyurethanes (TPUs) through a rational design by utilizing polyols having different molecular weights and diverse isocyanates (aromatic and aliphatic). Thorough characterization of these TPUs (ASTM and ISO standards) along with structure-property relationship studies were carried out for the first time and were then used as the encapsulation material for PSCs. The prepared TPUs were robust and adhered well with the glass substrate, and the use of low temperature during the encapsulation process avoided the degradation of the perovskite absorber and other organic layers in the device stack. The encapsulated devices retained more than 93% of their initial power conversion efficiency (PCE) for over 1000 h after exposure to harsh environmental conditions such as high relative humidity (80 ± 5% RH). Furthermore, the encapsulated perovskite absorbers showed remarkable stability when they were soaked in water. This article demonstrates the potential of TPU as a suitable and easily scalable encapsulant for PSCs and pave the way for extending the lifetime and commercialization of PSCs.

Accelerating the combinatorial optimization process for phosphor materials by Bayesian optimization

Abstract We investigated the acceleration of the combinatorial optimization process for phosphor materials using a machine learning method based on Bayesian optimization. Combinatorial pulsed laser deposition can be used to create a library of single-crystalline films with varying chemical compositions. However, the systematic evaluation of the target functional properties requires a long measurement time, impairing rapid material screening. In this study, Bayesian optimization was applied to sequential measurements of the photoluminescence (PL) properties of EuxY2−xO3 films to accelerate the combinatorial high-throughput evaluation. Although a conventional combinatorial PL evaluation of a binary composition-gradient film is composed of a sequential measurement of 80 points, the autonomous PL mapping technique based on Bayesian optimization drastically reduced the measurement points to only six points, demonstrating that the optimum chemical composition can be identified in a shorter experimental time.

A content-based collaborative filtering algorithm for movies and TVS recommendation

With the rapid development of multimedia technology and the constant upgrading of film and television libraries, users' demand for movies and television is increasing. How to accurately and timely find favorite movies from massive movie and television resources according to user's preferences and needs has become a great challenge. In recent years, the recommendation of movies and TVs has attracted a lot of research interest from academia and industry. The existing recommendation algorithms mainly include content based and collaborative filtering. The former recommends projects through collaborative learning of others' interests, while the content-based method examines the rich context of the project. In this paper, to further improve the performance of recommendations, a content based collaborative filtering method is proposed to provide recommendations for movies and television. Specifically, we extract and vectorize feature and category information from movies based on TF-IDF and apply truncated SVD to reduce the dimensions of the rating and TF-IDF matrix to retain the most representative information. We calculate the cosine similarity between the vectors from these two matrices. The final recommendation is to list 10 movies based on the average similarity of content and ratings. Extensive experiments on Amazon review data have proven the effectiveness of this method.

Fuzzy retrieval algorithm for film and television animation resource database based on deep neural network

The large amount of data in the film and television animation resource library leads to the increase of retrieval difficulty and the decrease of retrieval accuracy. Therefore, a fuzzy retrieval algorithm for film and television animation resource database based on deep neural network is designed. According to the structure of the film and television animation resource base and the static and dynamic characteristics of the color, texture and shape of the film and television animation, the deep neural network is used to supervise and learn the multi-layer neural network of the film and television animation and extract the characteristics of the film and television animation. The improved fuzzy C-means is used for feature clustering analysis. According to the results of feature clustering analysis, the fast sorting algorithm and Top-k sorting algorithm are used to obtain the retrieval results of the film and television animation resource library, and improve the retrieval accuracy of the film and television animation resource library. The experiment shows that using the 7th layer features of deep neural networks for animation resource retri of 90.15%. Therefore, this algorithm eval has the highest recall rate of 98% and the highest average precision rate meets the retrieval requirements of film and television animation resource libraries and can significantly improve the comprehensive performance of film and television animation resource library retrieval.

High-throughput methodology for the realization of high-entropy sub-nm equivalent-oxide-thickness high-dielectric-constant Ba(Ti,Zr,Ta,Hf,Mo)O3 film-based metal-oxide-semiconductor-related devices

This paper reports the use of a high-throughput sputtering technique for the fabrication of high-entropy high-dielectric-constant (high-k) Ba(Ti,Zr,Ta,Hf,Mo)O3 film libraries on Si substrates and sub-nm equivalent-oxide-thickness (EOT) metal−oxide−semiconductor (MOS) devices and metal−oxide−semiconductor field-effect transistors (MOSFETs). The elemental variations and amorphous microstructures are characterized using high-throughput X-ray fluorescence (XRF) and X-ray diffraction, respectively. The film library was patterned into 100 MOS configurations and the films with (Ba + Ti) = 0.41−0.47 at.%, (Mo + Zr) = 0.28−0.34 at.%, and (Ta + Hf) = 0.23−0.3 at.% exhibited favorably high k (325−374) and low tan δ (0.01−0.08) values with an impressive EOT ≈ 0.8−0.94 nm. The resulting MOSFETs after the rapid thermal annealing (RTA) exhibited excellent characteristics: an on/off current ratio of 8 × 106, saturated field-effect mobility of 138.4 cm2 V−1 s−1, a threshold voltage (VT) of 0.03 V, a subthreshold swing of 0.062 V⋅dec−1, and low interfacial defects of approximately 5.6 × 1010 eV cm−2. Small ΔVT and negligible changes in the maximum drain current were observed for the MOSFETs under various positive and negative gate-bias stress conditions before and after the RTA. Our devices outperformed various reported transistors, indicating the potential of the Ba(Ti,Zr,Ta,Hf,Mo)O3 films for use in a gate-first process for advanced gate stack-related devices.

IMMERSIVITY, DIGITALIZATION AND POLARIZATION: ELEMENTS RECONDITIONING THE CONTEMPOR ARY STAGE

Used to the immediacy of the cyberspace, theater artists around the world have sought ways to stay relevant in a reality that de-mands increasingly complex visual stimuli. Far from being replaced by audiovisual productions, theater seeks its own identity among the vast film library in streaming services. On the other hand, with the advent of repressive political correctness in the media, the stage runs the risk of entertainment becoming polarized, regardless of the position it comes from. The main characteristic of live productions is the exchange among an audience eager for new incentives, that is the «actor/spectator inter-action». This article explores this «actor/spectator interaction» with the techno-interaction provided by virtual reality tools, thus conditioning a performance into an uncompromising digital piece, providing the audi-ence with the necessary distance to express its opinion, without falling into alienation.

Projecting Creative Processes: Art Films and Art Education in Post-war Britain

The relationship between film and art education has received little scholarly attention. This paper describes and discusses one instance in the long and multifaceted history of this relationship: the educational uses of nonfiction films about art and artists in post-Second World War Britain, known then invariably either as ‘films on art’ or ‘art films.’ As a new international genre (backed by UNESCO’s educational distribution schemes), it gained particular momentum in the UK with the Arts Council of Great Britain, a public body, set up after the war with a mission ‘to increase the accessibility of the fine arts.’ And one of the ways it did was via 16mm projection. Alongside building a substantial film library, in 1950 the Council, in collaboration with the British Film Institute (BFI), started a new mobile cinema scheme, the Art Film Tour, to directly engage with the nontheatrical cinema sector, especially its educational venues. By drawing on my research in the Arts Council Archive, I propose to adopt a ‘historical pragmatics’ perspective and to study the Art Film Tour’s media configuration as a dispositif (Kessler, 2018). In the 1950s, with an increasing number of art films dedicated to artists at work, art students encountered cinematic renderings of the creative process by renowned modern artists, such as Picasso, Henry Moore and Jackson Pollock. And therefore, I make a case for an inductive analysis of ‘showing making’ on screen and its implications within historicised art education contexts.

Combinatorial screening via high-throughput preparation: Thermoelectric performance optimization for n-type Bi–Te–Se film with high average zT > 1

Thermoelectric materials have drawn extensive interest due to the direct conversion between electricity and heat, however, it is usually a time-consuming process for applying traditional “sequential” methods to grow materials and investigate their properties, especially for thermoelectric films that typically require fine microstructure control. High-throughput experimental approaches can effectively accelerate materials development, but the methods for high-throughput screening of the microstructures require further study. In this work, a combinatorial high-throughput optimization solution of material properties is proposed for the parallel screening and optimizing of composition and microstructure, which involves two distinctive types of high-throughput fabrication approaches for thin films, along with a new portable multiple discrete masks based high-throughput preparation platform. Thus, Bi2Te3–xSex thin film library with 196 throughputs for locating the optimized composition is obtained in one growth cycle. In addition, another thin film library composed of 31 materials with traceable process parameters is built to further investigate the relationship between microstructure, process, and thermoelectric performance. Through high-throughput screening, the Bi2Te2.9Se0.1 film with (00l) orientation is prepared with a peak zT value of 1.303 at 353 K along with a high average zT value of 1.047 in the interval from 313 to 523 K. This method can be also extended to the discovery of other functional thin films with a rapid combinatorial screening of the composition and structure to accelerate material optimization.

Tips and Tricks in Laparoscopic Adrenalectomy for Pheochromocytoma. How We Do It

"Pheochromocytomas are rare neuroendocrine tumors that frequently have genetic involvement and can present a particular risk in terms of the anesthetic-surgical procedure. Current worldwide medical recommendations state that laparoscopic adrenalectomy is the conventional treatment for pheochromocytoma, however, the ideal surgical strategy is still being developed as specialized surgeons gain experience with these rare tumors. The study's purpose was to thoroughly evaluate our film library and identify the best surgical steps that represent our standardized procedure. We developed a comprehensive set of surgical critical strategies for either a left or right adrenalectomy, providing helpful advice on patient positioning, port placement, the adrenal gland approach, as well as other surgical methods specifically designed for tumor mobilization and dissection. The current paper aims to synthesize our clinical experience in terms of preoperative preparation, patient positioning, intraoperative complications, causes of conversion, and specimen extraction. The main conclusions concern both the best surgical approach and the importance of surgical experience in the clinical management of these rare tumor types. "

История одного заказа: как Эсфирь Шуб и Дзига Вертов работали над фильмом к десятилетию революции

In September 1926, the Agitprop of the Central Committee commissioned a commemorative documentary film from the Moscow studio Sovkino to mark the tenth anniversary of the October Revolution. The film, under the working title Ten Years, was entrusted to the main documentary filmmaker of the era, Dziga Vertov. However, the chairman of the studio’s board, Ilya Trainin, opposed him as a candidate and put forward his own, a young filmmaker Esfir Shub. The bureaucrat removed Vertov from working on the commissioned film because he was sure that the director would not be able to make the film ideologically correct. Internal intrigues lead to Trainin barring Vertov’s access to the Sovkino film library and later seeking the director’s dismissal from the studio. The story of the film Ten Years demonstrates the changes in the perception of documentary films on the part of the party and the leadership. The article uses previously unpublished archival documents that shed light on the beginning of Esfir Shub’s work as a director, as well as on the details of Dziga Vertov’s dismissal from Sovkino.
