Evolution of microstructure and related optical properties of ZnO grown by atomic layer deposition.

2013

A study of transmittance and photoluminescence spectra on the growth of oxygen-rich ultra-thin ZnO films prepared by atomic layer deposition is reported. The structural transition from an amorphous to a polycrystalline state is observed upon increasing the thickness. The unusual behavior of the energy gap with thickness reflected by optical properties is attributed to the improvement of the crystalline structure resulting from a decreasing concentration of point defects at the growth of grains. The spectra of UV and visible photoluminescence emissions correspond to transitions near the band-edge and defect-related transitions. Additional emissions were observed from band-tail states near th…

Atomic layer deposition of AlN from AlCl3 using NH3 and Ar/NH3 plasma

2018

The atomic layer deposition (ALD) of AlN from AlCl3 was investigated using a thermal process with NH3 and a plasma-enhanced (PE)ALD process with Ar/NH3 plasma. The growth was limited in the thermal process by the low reactivity of NH3, and impractically long pulses were required to reach saturation. Despite the plasma activation, the growth per cycle in the PEALD process was lower than that in the thermal process (0.4A ° vs 0.7A ° ). However, the plasma process resulted in a lower concentration of impurities in the films compared to the thermal process. Both the thermal and plasma processes yielded crystalline films; however, the degree of crystallinity was higher in the plasma process. The…

De la oralidad literaria a la oralidad fílmica en tres modelos textuales de diálogo. "La colmena": novela, guion, filme

2019

La colmena novela y La colmena filme son dos géneros narrativos cuyos procesos de textualización, si bien remiten a la misma historia, difieren entre sí. Por su parte, en la película, el relato cinematográfico opera narrativa y descriptivamente a partir de la secuenciación de imágenes en las que coexisten entre otros elementos: acción, espacios, movimiento y diálogos de personajes. El resultado es una concreción de la historia dada en forma multimodal. En la novela todo es verbal, discursivo: la textualización es una sucesión de formas lingüísticas con poder evocador. El nexo común más relevante que comparten, aparte de la historia contada, son los diálogos de los personajes. Por su parte, …

High pentacene transistor performance by engeneering morphology of solution processed thin films

A novel intrinsically disordered outer membrane lipoprotein ofAggregatibacter actinomycetemcomitansbinds various cytokines and plays a role in biofil…

2017

Intrinsically disordered proteins (IDPs) do not have a well-defined and stable 3-dimensional fold. Some IDPs can function as either transient or permanent binders of other proteins and may interact with an array of ligands by adopting different conformations. A novel outer membrane lipoprotein, bacterial interleukin receptor I (BilRI) of the opportunistic oral pathogen Aggregatibacter actinomycetemcomitans binds a key gatekeeper proinflammatory cytokine interleukin (IL)-1b. Because the amino acid sequence of the novel lipoprotein resembles that of fibrinogen binder A of Haemophilus ducreyi, BilRI could have the potential to bind other proteins, such as host matrix proteins. However, from th…

DFT Prediction of Enhanced Reducibility of Monoclinic Zirconia upon Rhodium Deposition.

2018

Oxides are an important class of materials and are widely used, for example, as supports in heterogeneous catalysis. In a number of industrial catalytic processes, oxide supports actively participate in chemical transformations by releasing lattice oxygen anions. While this is intuitively understood for reducible oxides, the reducibility of irreducible oxides may be modified via nanoengineering or upon inclusion of foreign species. Our calculations predict that the ability of irreducible monoclinic zirconia to release oxygen improves substantially upon deposition of rhodium. Through a comprehensive screening of Rh/ZrO2 with different size of the rhodium species, we find that a Rh adatom and…

Wykorzystywanie seksualne małoletnich przez duchownych w kinematografii: nierozpoznane znaki czasu

2021

Contemporary theology applies the old notion of loci theologici also to media and film. It is not only films that are directly religious (biblical, hagiographies, etc.) that have theological significance, but also those that take up topics related to the Church in a critical way. Therefore, one should be aware of the appearance of successive films, documentaries and feature films, which raise the issue of sexual abuse against the youngest (paedophilia) also in the Church. The article presents the most important films, whose authors present the perpetrators of paedophilia, the mechanisms leading to its concealment and silence not only in the Church, but also in the media and society, as well…

Buccal Thin Films as Potent Permeation Enhancers for Cytisine Transbuccal Delivery

2022

Cytisine (CYT) is a powerful anti-smoking compound which could greatly benefit from transbuccal delivery because of both its unfavorable pharmacokinetics after oral administration and its intrinsic ability to permeate the buccal mucosa. This work aims to design CYT-loaded buccal thin films suitable for transbuccal drug delivery due to its capability of promoting the interaction between CYT and the buccal membrane. The solvent casting method was employed to prepare several thin films combining various excipients such as matrixing polymers, mucoadhesion agents, plasticizers and other compounds as humectants and sweeteners, component ratios and solvents. A total of 36 compositions was prepared…

Asymmetric hysteresis for probing Dzyalohsinskii-Moriya interaction

2016

The interfacial Dzyaloshinskii-Moriya interaction (DMI) is intimately related to the prospect of superior domain-wall dynamics and the formation of magnetic skyrmions. Although some experimental efforts have been recently proposed to quantify these interactions and the underlying physics, it is still far from trivial to address the interfacial DMI. Inspired by the reported tilt of the magnetization of the side edge of a thin film structure, we here present a quasi-static, straightforward measurement tool. By using laterally asymmetric triangular-shaped microstructures, it is demonstrated that interfacial DMI combined with an in-plane magnetic field yields a unique and significant shift in m…
