Authors: Qiu Yu , Gerstel Peter , Jiang Linqin , Lipowsky Peter , Bauermann Luciana Pitta , Bill Joachim 
Published: March 2022

Abstract
Crystalline In(OH)3 and UV-emitting In2O3 thin films with a unique columnar morphology have been successfully prepared for the first time via a simple aqueous solution deposition method. In the present study, sulfonate-terminated self-assembled monolayers on single-crystal Si wafers were used as substrates for the film deposition. Uniform In(OH)3 thin films formed on self-assembled monolayers in aqueous solutions of InCl3 · 4H2O at 60°C. These films, containing columnar In(OH)3 crystals, showed preferential growth orientation along the [100] direction. The current understanding of the film formation mechanism was discussed. After annealing in air at 400 °C, these films were converted to nanocrystalline In2O3 films without modification of the morphology. Photoluminescence emission from In2O3 films was reported at approximately 3.4 eV, which was ascribed to the near-band-edge emission.
Nanoindentation creep and stress relaxation tests of polycarbonate: Analysis of viscoelastic properties by different rheological models
Authors: Schiffmann Kirsten Ingolf 
Published: March 2022

Abstract
Feedback-controlled nanoindentation with a Berkovich diamond tip has been used to perform creep and stress relaxation tests on polycarbonate at room temperature for a wide range of loads (10 – 30000 μN) and indentation depths (30 – 3000 nm). The creep compliance J(t) and relaxation modulus G(t) have been calculated from experimental data as a function of time in the range t = 0.1 – 100 (1000) s. The data are analysed by different rheological models which are compared: (1) the Burgers model, (2) the generalised Maxwell/generalised Kelvin model, and two empirical approaches: (3) a logarithmic model, and (4) a power law model. The Burgers model gives a poor description of the material behaviour since it assumes a steady-state flow of material which is not observed in the experimental time range. The generalised models yield a set of discrete relaxation- and retardation time constants. It is shown that these time constants do not correlate with specific molecular moving processes in the polymer, but are only one of several possible parameterisations of the creep and relaxation curves. Numerical differentiation of G(t) and J(t) shows that polycarbonate has continuous relaxation- and retardation time spectra, respectively, and the dynamic viscosity η(t) of the material increases linearly with time. The behaviour of polycarbonate is best represented by the empirical power law model, which allows optimum fit of creep/relaxation curves, relaxation and retardation time spectra and time-dependent viscosity.
Multiwall carbon nanotubes-based composites – mechanical characterization using the nanoindentation technique
Authors: Olek M. , Kempa K. , Giersig M. 
Published: March 2022

Abstract
We report on mechanical properties of multiwall carbon nanotubes (MWNTs)-polymer composites using the nanoindentation technique. The nanoindentation experiments conducted on thin films containing MWNTs revealed that the presence of nanotubes does not affect the nanomechanical properties of the composites. Even a layer-by-layer assembly of MWNTs with a high concentration and a homogeneous distribution of carbon nanotubes does not ensure reinforcement of the composites. For that reason, we synthesized and utilized carbon nanotubes with a silica shell. Nanohardness and Young’s modulus have been found to increase strongly with increasing content of these nanotubes in the polymer matrix. The silica shell on the surface of a nanotube enhances its stiffness and rigidity. Our composites, at 4 wt.% of the silica-coated MWNTs, display a maximum hardness of 120 ± 20 MPa and a Young’s modulus of 9 ± 1 GPa. These are, respectively, 2 and 3 times higher than those for the polymeric matrix.
Thermodynamics of high-temperature cuprous sulfide
Authors: Arita Minoru 
Published: March 2022

AbstractPublished measurements of the diatomic sulfur fugacity were used to make a thermodynamic analysis of high-temperature cuprous sulfide between 789 K and 1321 K. Gibbs–Duhem integration of the fugacity data was used to determine the enthalpy of formation of stoichiometric Cu2S as – 123.8 kJ mol–1. Statistical thermodynamics was applied to find partition functions, interaction energies, and free energies to characterize the configurational aspects of the phase. Theoretical calculations indicated that Cu vacancies might be localized in one half of the Cu lattice sites under quasi-chemical equilibrium.
Thermodynamic modeling of the sodium alanates and the Na–Al–H system
Authors: Qiu Caian , Opalka Susanne M. , Olson Gregory B. , Anton Donald L. 
Published: March 2022

Abstract
The thermodynamic properties of the Al –Na and Na–Al – H systems have been assessed by combining the “calculation of phase diagram” approach with first-principles predictions. The Gibbs energies of the individual phases were thermodynamically modeled, where the model parameters were obtained from best fit optimizations to combined experimental and first-principles predicted finite temperature data. The first-principles thermodynamic predictions were based upon density functional theory ground state minimizations and direct method lattice dynamics. The predictions proved to be important adjuncts to the assessments whenever experimental measurements were lacking or not feasible. It was shown that the phase stability conditions of sodium alanates, NaAlH4 and Na3AlH6, were well described with the present models.
Density and excess volumes of liquid copper, cobalt, iron and their binary and ternary alloys
Authors: Brillo Jürgen , Egry Ivan , Matsushita Taishi 
Published: March 2022

Abstract
The densities of liquid copper, cobalt, and iron, their binary and ternary alloys have been measured over a temperature range including the undercooled regime. A non-contact technique was used, consisting of electromagnetic levitation combined with optical dilatometry.
For all samples, the density was a linear function of temperature. The concentration dependence was studied by means of the excess volume which was negligible for Co– Fe and positive for Cu– Fe, Cu– Co, and Cu–Co – Fe.
The density of the ternary alloy could be predicted from the excess volumes of the binary phases without the need to introduce any ternary interactions.
Effect of a low frequency electromagnetic field on the direct-chill (DC) casting of AZ80 magnesium alloy ingots
Authors: Guo Shijie , Le Qichi , Zhao Zhihao , Han Yi , Cui Jianzhong 
Published: March 2022

AbstractThe effects of a low frequency electromagnetic field applied during semi-continuous direct-chill casting on AZ80 ingots were investigated. The experiments were performed both in the absence and in the presence of the electromagnetic field. In contrast to the ingot cast in the conventional process, the microstructure of the ingot was significantly refined by the electromagnetic field and a high degree of grain refinement was realized when the operating frequency was at 22 Hz. The ingot exhibited a relatively increased and uniform distribution of Vickers hardness and decreased segregation of Al when the operating frequency of the electromagnetic field was in the range of 15– 30 Hz.
A molecular dynamics study on the mechanical properties of defective CNT/epoxy nanocomposites using static and dynamic deformation approaches
Authors: Afsharhashemkhani Sina , Jamal-Omidi Majid , Tavakolian Majid 
Published: March 2022

Abstract
In this paper, the mechanical behavior of epoxy polymer nanocomposite with continuous single-walled carbon nanotubes (SWCNT) with and without vacancy defects has been investigated based on two approaches of deformation, molecular mechanics (static) and molecular dynamics. In this regard, molecular simulation has been performed on the basis of the compass force field. In order to validate the research steps, the results obtained for pure epoxy polymer were compared with similar molecular dynamic simulations, which confirmed the simulation process. The research process proposed a method for controlling the symmetry of the system during equilibration with an asymmetric barostat. The Souza-Martins barostat was also used to apply loading and deformation control over a constant strain rate range. The results showed that in both deformation approaches (with and without calculating the contribution of kinetic energy), the presence of defects improved the transverse tensile and shear moduli, while the longitudinal tensile modulus decreased. Also, the improvement and decrease of the longitudinal tensile modulus and longitudinal shear modulus of the nanocomposite in comparison with the net polymer have been observed in both approaches, respectively. As a general result, it was observed that the contribution of kinetic energy has a major effect on the mechanical properties of pristine and defective nanocomposites.

On a dichotomy of question types: the case of Mandarin Chinese and Changsha Xiang
Authors: Her One-Soon , Che Dewei , Bodomo Adams 
Published: March 2022

AbstractContrary to the conventional three-way distinction of questions: polar questions, disjunctive questions, andwh-questions, we argue for a more revealing two-way distinction of polar versus constituent questions, the latter with two subtypes: disjunctive andwh-questions. Following Bhatt, Rajesh & Veneeta Dayal. 2020. Polar question particles: Hindi-Urdu kya. Natural Language & Linguistic Theory 38. 1115–1144 proposal that polar questions denote singleton sets of propositions and the standard view that disjunctive andwh-questions denote sets with multiple propositions, we further characterize this dichotomy pragmatically as confirmation-seeking (CS) and information-seeking (IS), i.e., polar questions seek confirmation of the proposition put forth, while constituent questions seek information specifically targeted by the interrogative constituent. This dichotomy is formally detected in Mandarin Chinese via the question particlemaversusne, dichotomy of fragment questions, adverbnandao‘don’t tell me’ versusdaodi‘after all’, respective (in)ability to serve as indirect questions, and an intervention effect on constituent questions. We then discuss the typological implications of this two-way distinction and demonstrate that the Changsha dialect of Xiang, another Sinitic language, has no CS polar questions as the alleged polar questions are all disjunctive questions. This fact suggests that, while there are two major types of questions cross-linguistically, CS polar questions are not universal.
A parte ficta totum fictum: Fanciful Illustrations of Sea Animals in the Liber de natura rerum and Other Medieval Encyclopedias*
Authors: Šedinová Hana 
Published: March 2022

Abstract
Six of the twenty books of Thomas of Cantimpré’s thirteenth-century Liber de natura rerum are devoted to zoology, and two of them contain descriptions of strange sea animals whose names are often hard to make sense of, both etymologically and semantically. Illuminators had to work with textual descriptions lacking essential information, and in many cases the encyplopedist himself made matters worse by focussing on the most bizarre and peculiar traits of animals encountered in his antique and medieval sources. Consequently, some of the illuminators produced images fanciful enough to make it look like they got carried away by their own imagination. However, a detailed comparison between text and image reveals that artists did their best to follow textual descriptions – it is the literal interpretation of their sources that often strikes us as unexpected and perplexing.
Hadis dan Ilmu Hadis dalam Pandangan Ahl al-Sunnah dan Syiah
Authors: Ahmad Jumal 
Published: March 2022

This study focused on hadith and the science of hadith in the view of Ahlus Sunnah and Shia. Ahl al-Sunnah and Shia view the hadith as a source of Islam. The existence of different cultural roots of each group makes the Hadith can not be separated from the interests of group authority. The Shi'a believe that the revelation did not stop after the death of the Prophet Muhammad. In the verification of the hadith, the Shi'ah provided the criteria for the existence of a continuation of the ma'shum and all the narrators in the sanad came from the Shi'a group at all levels.

Authors: Syahriyati Alfi 
Published: March 2022

This paper aims to discuss the Hadith in the book of Faḍāil A'māl by Maulana Zakariyya al-Kandahlawi. This book is the primary reference for the Tablighi Jamaat group in practicing the sunnahs of the Prophet Muhammad pbuh. By adopting the al-Irāqi method in capturing the book (takhrīj al-kitāb) of Iḥyā ‘Ulūm al-Dīn, this paper traces the authenticity of the Hadiths and potrays the interaction of the Tablighi Jamaat group with the book which later became a tradition in daily life. This paper find that there are 22 authentic (Ṣaḥiḥ) Hadiths, 1 good (Ḥasan) Hadith, 9 weak (dā’if) Hadith, 5 very weak (da’īf jiddan) Hadith, 1 fabricated (maudu’) Hadith, and 2 la aṣla lahu (lam ajidhu) Hadith in Faḍāil A'māl Book.
Estudos de gênero na pesquisa em jornalismo no Brasil
Authors: Martinez Monica , Lago Claudia , Heidemann Vanessa 
Published: March 2022

Em pesquisa anterior na base de dados da SBPJOR (Associação Brasileira de Pesquisadores em Jornalismo) (MARTINEZ; LAGO; LAGO, 2016), que cobre o período 2010-2014, apontamos para um possível boom das pesquisas relacionando jornalismo aos estudos de gênero. Neste presente levantamento, realizado na base de dados dos grupos de pesquisa de jornalismo da Intercom nos últimos cinco anos (2016-2020), comprovamos este aumento quantitativo dos trabalhos. Apesar do incremento, permanece uma relação tênue na questão da integração teórica dos dois campos de estudo, na medida em que boa parte dos trabalhos apresentados não incorpora de forma consistente a vasta perspectiva dos Estudos de Gênero, mantendo um tipo de pesquisa com caráter descritivo (PERUZZO, 2018), não aprofundando a possibilidade de utilização do conceito de gênero enquanto uma categoria de análise (SCOTT, 1995) operacional para entender o campo do Jornalismo.

Abstract

Background
A first approach addressed to ascertain whether emotion regulation (ER) could be a transdiagnostic construct between eating disorders (EDs) and gambling disorder (GD) (through a joint clinical clustering analysis of both disorders) was performed by Munguía et al. (2021). Both conditions were represented by a severe, moderate, and low ER profile subgroups, according to the degree of ER difficulties. Results showed a linear relationship between the severity of ER difficulties and the severity of the disorder and the psychopathological state.

Aims
Based on the aforementioned cross-sectional study, the objective of this longitudinal research was to explore the treatment response of the different ER subgroups.

Methods
459 adult patients (n = 277 ED; n = 182 GD) were included. Several clinical variables, as well as outcome indicators (after completing 16 weeks of cognitive-behavioral therapy), were evaluated.

Results
The three subgroups found in the previous cross-sectional study were taken for the performance of the present research. ED and GD distribution in each subgroup replicates the one exposed by Munguía et al. (2021), as well as their characterization, considering psychopathology, disorder severity and personality traits. The low ER subgroup reported a better response to treatment, whereas the severe group had the highest rates of non-remission and dropouts.

Conclusions
Our results suggest that greater difficulties in ER lead to poorer treatment outcomes. Therefore, tailored treatments for patients with poor ER abilities would be recommended to improve adherence and treatment outcomes.

Chemical conversion of synthesis gas to hydrocarbons and other products under the condition of the method known as "aerosol nanocatalysis" has been studied.
A laboratory installation was developed and experimental studies were carried out in the range of process-dependent parameters: pressure from 0.1 to 1.0 MPa, temperature from 483 to 533 K, catalyst concentration from 5 to 25 g/m3 of reactor volume, and mechanochemical activation intensity from 4, 0 to 11.2 Hz. It was found that an increase in pressure from 0.1 to 1.0 MPa gradually increased the conversion degree from 44.1 % to 56.5. An increase in pressure of the FTS process in conditions of aerosol catalysis from 0.1 to 1.0 MPa contributed to a stable yield growth from 14 to 17 %. Selectivity reached its maximum value of 93.1 % at a pressure of 0.3 MPa. Dependence of selectivity on the catalyst MCA intensity was characterized by the constant growth of selectivity of carbon monoxide conversion to hydrocarbons with an increase in MCA frequency from 4 to 8.5 Hz while maximum selectivity reached 91 %. With a further increase in MCA frequency to 11.2 Hz, a decrease (to 83.5 %) in the value of selectivity of carbon monoxide conversion to hydrocarbon products in the FTS process was observed. Therefore, it was recommended to consider the value of the MCA frequency from 6 to 10 Hz as an acceptable range. Maximum yield (73 wt %) of hydrocarbon fraction with a chain length from 5 to 6 carbon atoms was observed for a pressure of 0.3 MPa. The minimum yield was 35 wt % for a pressure of 1.2 MPa. At other pressure values (0.1–0.2 and 0.4–1.1 MPa) of experimental studies, the yield of this fraction varied within 38–52 wt %. A block diagram of experimental-industrial FTS installation based on principles of aerosol nanocatalysis was offered.
Modeling the wetting of titanium dioxide and steel substrate in water-borne paint and varnish materials in the presence of surfactants

Published: March 2022

This paper reports the results of studying the effect of two additives such as polyether siloxane (PS) and sodium polyacrylate (SPA) on the wetting of various substrates in water-borne paints (WB paints).
Titanium dioxide (TiO2), paraffin (PA), steel (ST), and glass (GL) were used as solid substrates. The edge wetting angle (θ0) and the ratio (dCosθ/dСS) were used as the criterion for assessing the wettability of solid substrates. In aqueous solutions (without acrylic resin), both surfactants improve the wetting of the substrates. For PS, all the substrates studied, depending on θ depression, can be arranged in a row: ST>PA>GL>TiO2.
For SPA: PA>TiO2>GL>ST. The introduction of an acrylic film-forming agent in the composition enhances the wetting ability of SPA (in comparison with the aqueous solution of surfactants). With an increase in the concentration of SPA from 0 to 4 g/dm3 in acrylic resin solutions, the edge wetting angle of steel decreases by 6÷8° (while in water by only 3°).
With respect to TiO2, the wetting activity of SPA does not depend on the acrylic content of the water. PS in acrylic-containing compositions exhibits worse wetting activity than SPA. The introduction of surfactants in the compositions improves the quality of coatings. With optimal SPA contents in the compositions, the corrosion rate of coatings is reduced (in distilled water by 45 %, in 60 % NaCl solution by 60 %). At the same time, the gloss of coatings increases by 50 % while adhesion increases by 2 points (according to ISO 11845: 2020). This is fully correlated with the nature of the effect of surfactants on the wetting of the steel substrate and pigment (titanium dioxide). Based on probabilistic-deterministic planning, the compositions of WB paints were optimized, ensuring their maximum wetting of TiO2 and ST. Equations for calculating cosθ depending on the content of acrylic polymer and surfactants have been derived
