Porous Ultra-Capacitor Electrodes Fabricated by Solution Precursor Plasma Spray: Molybdenum Oxide vs. Molybdenum Nitride
Authors: Golozar M. , Chien K. , Coyle T.W. 
Published: January 2023

Abstract
Solution precursor plasma spray has been shown capable of depositing high surface area transition metal oxide coatings of interest as ultra-capacitor electrodes. These materials exhibit mixed double layer and pseudo-capacitive properties, enabling larger charge storage capacity than electrical double layer capacitor electrodes such as carbon. This investigation explored potential of SPPS to deposit molybdenum oxide with microstructures suitable for use as pseudo-capacitive electrodes. It further identified a two-step temperature-programmed heat treatment that resulted in the topotactic phase transformation of the α-MoO3 deposits into high specific surface area molybdenum nitrides exhibiting a higher electrochemical stability window (i.e. a higher specific area capacitance). The electrochemical behavior of molybdenum oxide and molybdenum nitride deposits formed under different deposition conditions was studied using cyclic voltammetry in order to assess the influence of the resulting microstructure on the charge storage behavior and potential for use in ultra-capacitors.
A Laser Surface Texturation to Control the Coating-Substrate Interface

Published: January 2023

Abstract
Surface state plays an important role in particle bonding and formation of the first layer of coatings in thermal spraying. From a chemical aspect as well as a mechanical point of view, in all cases, the substrate surface needs to be optimized to promote the adhesion of the sprayed particles and then the coating. In order to control such parameters, several works have been conducted to avoid drawbacks on sensitive materials. This study aims at developing a laser surface texturation before the spraying process to improve the coating adherence. According to the laser parameters, different surface morphologies (hole diameters, surface roughness, hole depth, etc.) can be developed. The surface material morphologies were characterised by SEM and bond strength was evaluated through ASTM C633 pull tests. This approach has been applied on the system Al 2017 / NiAl and demonstrates a high influence of the laser treatment. However, the thermal effect induced during the laser-matter interaction has to be controlled to avoid negative effects of the substrate properties particularly tribological properties. In this case, a study of the effect of the conventional processes and texturing process on the fatigue properties of substrate were studied.

Abstract
In this study, porous molybdenum (Mo) materials were prepared by flame spraying semi-molten particles to low velocity levels. The influence of spray particle state, including particle velocity and melting degree, on microstructure and porosity was investigated to understand the formation mechanism of the pore structure and connection between particles. The results showed that Mo sprayed particles at low velocities (&lt;20 m/s) and limited semi-molten state can be generated by flame spraying. The annealed Mo deposits with the porosity ranged from 39% to 61% were deposited. High porosity in the deposit was achieved through the shielding effect of deposited particles, bonded by the settled melt in the particle/particle interface. Moreover, the porosity generally decreased with the increase of melting degree of spray particles prior to impact.

Abstract
The main goal of this work is to improve the coating properties of three-cathode atmospheric plasma sprayed coatings with respect to porosity and residual stresses. This was done by use of numerical simulation coupled with advanced diagnostic methods. A numerical model for the triple injection of alumina feedstock, as well as acceleration and heating of the powder particles in the characteristic threefold symmetrical plasma jet cross section produced by a three-cathode-plasma torch was developed. The modeling results for the standard injector’s position “0” were calculated and experimentally verified by Laser Doppler Anemometry (LDA). Based on the criteria defined for concentrated feedstock transport and homogeneous thermal treatment of powder particles in the plasma jet, the optimal injection position was found. In the next step a previously developed, coupled CFD-FEM-simulation model was used for simulations of the coating build-up, describing flattening, solidification and deformation due to shrinkage for alumina particles on a rough substrate surface.
Developments to Influence Coating Properties and to Reduce Fine Particulate in Arc Spraying
Authors: Kroemmer Werner , Heinrich Peter 
Published: January 2023

Abstract
The basic idea when using common plasma gases for arc spraying with their varying levels of energy was first of all to achieve higher system efficiency and to produce coatings with fewer oxides. The differentiation between the open arc process and plasma spraying is the advantage using active gases with a much higher energy level, for example using fuel gases to influence the process characteristics and to get high end coatings. As these results from this work in arc spraying show, the increased need for research into this technology at the moment is definitely of importance. The main market of arc spraying can be found in the area of corrosion protection, the technology’s growth stems from those areas which are interested in manufacturing high-quality coatings with substantially more cost-effective wire. In order to broaden the range of thermal spray applications, we have endeavored to investigate the issue of the right gas mix for arc spraying. In doing so, it was concluded that, by using wire as the spray material, this cost-effective process can often be used as an equally viable alternative to other methods. The optimization of costs and tailoring of coating properties to suit specific applications are just some of these influencing variables.
Development and Psychometric Evaluation of the HIV-Related Stigma in Health Facilities (HIV-SHF) Scale
Authors: De los Santos Janet Alexis A. 
Published: January 2023

Objective: The literature presents a variety of Human Immunodeficiency Virus (HIV) stigma scales focused on the self, social aspects, and health worker issues. Scarcity was noted on instruments developed to assess HIV-related stigma in health facilities. This paper aims to present the rigors in designing and developing a psychometrically reliable and valid scale to assess HIV-related stigma in health facilities. Material and Methods: A sequential exploratory mixed method design was utilized following a Qual-Quan approach. Key informant interviews were used to gather first-hand experience of stigma in health facilities among key populations and persons living with HIV. Thematic analysis was utilized to analyze the narratives and pick out statements for item generation in the scale. The quantitative phase was done through item and scale validation, exploratory factor analysis, and reliability assessment using Cronbach’s alpha. Results: Two factors were extracted which were categorized as (1) Facility Structure and Protocol, and (2) Health Personnel. The scale has very high internal consistency as per Cronbach’s alpha value of 0.91, suggestive of its high reliability in measuring HIV-related stigma in health facilities. Conclusion: The scale may be utilized by health facilities to assess and evaluate their health service provision, particularly on their client’s perception of health facility-related stigma.
Структурно-полевой подход к синтаксической фразеологии русского языка. Часть I
Authors: Pavlova Anna 
Published: January 2023

The paper deals with the problems of the structural-field approach to the study of linguistic phenomena. The foundations for building a field theory in the grammatical structure of language were laid by V. G. Admoni in his works on the theoretical grammar of German. Effectively, the same approach can be applied to any language phenomenon as it has a number of advantages over classifications involving the distribution of objects in systems of level hierarchy. The paper demonstrates the advantages and possibilities of the structural-field approach. It aims at studying the field of syntactic phraseological phenomena (phraseme constructions), identifying its core, centre, periphery, and adjacent fields. Phraseme constructions belong to the linguistic system and occupy an important place in construction grammar. They are constantly reproduced in spoken language and filled in with concrete vocabulary. They are stable syntactic models of idiomatic character that are retrieved from memory as whole entities rather than by separate units (the meaning of a filled model cannot be deduced without prior knowledge of its structure and its semantics per se). The properties, namely polyelementality, reproducibility, stable syntactic structure, idiomaticity, fillability in speech, are indispensable characteristics of the phenomenon described herein: deprived of at least one of them, a construction ceases to be a phraseme. However, phraseme constructions have a larger, typical set of characteristics. In this paper, they are viewed from the perspective of an increase and decrease of these characteristics, making the study of phraseological constructions as a field whose structure is determined by multiple axes possible. The structural-field approach waives the need to make clear distinctions between linguistic phenomena with similar functionality at different levels. The use of the field approach and its methodological advantages are explained through the example of the field of syntactic phraseology.
De L'éclaircissement sur le sacrifice de Joseph de Maistre à la ‘révélation’ de Durkheim
Authors: de Balanda Flavien Bertran , Béra Matthieu 
Published: January 2023

Abstract
This article examines how the counter-revolutionary writer Joseph de Maistre (1753–1821) theorizes the notion of sacrifice. For de Maistre sacrifice understood as punishment is foundational to all societies. Durkheim used many of this author's works without citing them. At the time Durkheim was teaching his criminal sociology course on punishment and responsibility as well as preparing his course on religion dealing with ‘revelation’. It is possible to explain his interests by the fact that de Maistre appears in Durkheim's core readings for theoretical ‘juncture’ that featured authors concerned with the articulation between questions of penal law and of religious phenomena. This provides additional evidence that for Durkheim religion is at the origin of the definition of the crime and of the establishment of the punishment.

Résumé
Cet article examine comment l'essayiste contre-révolutionnaire Joseph de Maistre (1753–1821) théorise la notion de sacrifice: pour lui, le sacrifice est compris comme une peine et il est à l'origine de toutes les sociétés. Or Durkheim fit usage de plusieurs de ses livres sans jamais les citer. Alors qu'il dispensait son cours de sociologie criminelle sur la peine et la responsabilité, et préparait sans doute aussi le cours sur la religion, dit ‘de la révélation’, il emprunta l'essai sur le sacrifice de de Maistre. On peut expliquer cet intérêt par le fait que De Maistre fait partie des lectures spéciales de ‘charnière’ théorique, qui renvoient à des auteurs se situant à l'articulation des questions de droit pénal et des phénomènes religieux repérés par Durkheim. On peut aussi, en conséquence, y voir une preuve de plus que, pour Durkheim, la religion est à l'origine de la définition du crime et de l'établissement de la peine.

Investigasi Kualitas Udara Ruang Kelas dengan Perubahan Ventilasi Aktif Menjadi Alami Pasca Pandemi di Daerah Tropis Lembab
Authors: Setiati Tri Woro , Febrina Sandra Eka , Islami Fajar Sadik 
Published: January 2023

Pandemi Covid-19 memberikan dampak dan perubahan yang cukup signifikan dalam kehidupan manusia. Penggunaan masker, aturan mencuci tangan, jaga jarak serta perubahan sistem ventilasi ruang dalam dari buatan menjadi alami kembali. Sebelum masa pandemi, rata-rata sekolah telah menggunakan air conditioning untuk menjaga kualitas udara dalam. Namun, kondisi pasca pandemic memaksa seluruh ruang memanfaatkan kembali ventilasi alami. Kondisi tersebut mengharuskan jendela di ruang kelas terbuka untuk memaksimalakan pertukaran udara. Tentu saja kualitas udara di dalam ruang akan berbeda dengan sebelumnya. Berdasarkan permasalahan tersebut, penelitian ini bertujuan untuk menginvestigasi kembali kualitas udara ruang kelas yang mengalami perubahan dari penggunaan sistem ventilasi buatan menjadi alami. Investigasi dilakukan dengan pengukuran kualitas udara dengan beberapa parameter diantaranya konsentrasi partikulat (PM 2,5; PM 1,0 dan PM10), kecepatan udara, temperatur dan kelembapan udara serta HCHO dan TVOC. Metode penelitian dilakukan dengan pengukuran langsung kualitas udara pada ruang kelas yang menggunakan ventilasi alami serta ruang kelas yang menggunakan air conditioning dalam waktu yang sama. Hasil komparasi menunjukkan bahwa, kualitas udara pada ruang kelas dengan ventilasi alami lebih baik, berdasarkan evaluasi kecepatan udara, nilai HCHO dan TVOC. Namun, untuk nilai konsentrasi partikulat menunjukkan nilai yang lebih tinggi dikarenakan jendela yang terbuka memberikan kesempatan debu dan emisi kendaraan masuk secara langsung.
