Syrian Refugee Resettlement in Canada
Authors: Canefe Nergis
Published: November 2023

This web archive strives to offer a documented commentary on the most recent addition to the Canadian resettlement scheme, the Blended Visa Office-Referred (BVOR) program. The program constitutes a modified version of private sponsorship of refugee and immigrant applicants; it has to be examined in relation to both private and government resettlement schemes, and in comparison to the historical use of private sponsorship for Indochinese refugees. The documents presented here allow an examination of the background debates that led to the institutionalization of the BVOR program, the challenges BVOR is intended to address, public and political debates concerning the proposed division of public and private responsibility, and the links made between this particular model and the public acceptance of the en masse resettlement of select Syrian refugees in Canada​. This refugee crisis raises important political and legal questions for both the Canadian public and Canadian policymakers. Who is deemed to be a deserving refugee, who is eligible for resettlement and based on what criteria, keeps changing. The current and future saliency of migration could be succinctly revealed by examining factors such as which categories of migration hold significance, how they are constructed and determined, and by whom. The debate continues and must do so above and beyond policy measures, legal requirements and formal immigration regimes. It is also of utmost importance to underline that private sponsorship programs are to be in place as a complementary element to government-assisted resettlement commitments. They cannot eradicate the necessity of the Canadian government to fulfill its international obligations and humanitarian commitments in the face of mass displacements. The Syrians are unlikely to be the last group to suffer such a fate.
Financial Performance and Green Supply Chain Management in a South African National Electrical Energy Provider
Authors: Langton Irvine , Maotoawe Nelson , Mafini Chengedzai
Published: November 2023

Introduction: The body of literature on green supply chain management (GSCM) in various organisations has increased steadily. However, contextual literature on GSCM is still limited, such as within the electrical energy sector in developing countries such as South Africa.
Purpose/objectives: The study examined the relationships between internal GSCM (IGSCM), customer monitoring (CM) and -supplier monitoring (SM), customer-supplier collaboration (CC, SC), and financial performance at Eskom Holdings, the national electrical energy provider in South Africa.
Design/ Methodology: The study employed a quantitative approach design on a sample of 350 supply chain professionals drawn from various Eskom depots nationwide. Hypotheses were tested using structural equation modelling based on the SMART partial least squares (PLS) technique.
Findings: IGSCM positively impacted customer and supplier monitoring and collaboration, linked to higher financial performance. However, IGSCM negatively impacted financial performance.
Practical implications: To managers in the electrical energy sector, the study suggests that implementing IGSCM, SM, CM, CC, and SC activities is key in influencing the level of FP. Similarly, it is important to implement IGSCM activities in tandem with customer and supplier monitoring and collaboration if gains in FP are to be realised.
Originality/Value: This study contributes to GSCM literature as it is one of the few studies that explore IGSCM, customer and supplier monitoring, customer-supplier collaboration, and financial performance within a South African national electrical energy provider.
Unsupported Pt nanoparticles: Synthesis, Deactivation, and Hydrogen Electrocatalysis in Unpurified Electrolytes
Authors: Patil Rituja , Roenigk Samantha , Shirwalkar Advay , Meng Qiudi , McKone James
Published: November 2023

Platinum is ubiquitous in electrochemical catalysis owing to its ability to accelerate redox reactions involving surface-bound hydrogen and oxygen. Accordingly, Pt is used as a calibration standard and activity benchmark against which novel electrocatalysts are compared. These measurements are often executed in unpurified, reagent grade electrolytes where Pt is also susceptible to deactivation by several routes. This constitutes a challenge where the ease of making measurements with Pt-based catalysts must be balanced against the difficulty of obtaining accurate and consistent results. We report herein a synthetic procedure for unsupported Pt nanoparticles that uses readily available reagents and laboratory apparatus, with the goal of making high-quality control experiments in electrocatalysis as accessible as possible. We also identified conditions under which these particles deactivate in unpurified aqueous acid and base and differentiated between mechanisms involving catalyst poisoning, which dominates at more negative applied potentials, and particle growth, which dominates at positive potentials where Pt-oxide species are produced. Finally, we demonstrated that unsupported Pt nanoparticle films can be used to good effect for reference electrode calibration and benchmarking of hydrogen evolution/oxidation electrocatalysts, even in unpurified electrolytes, provided steps are taken to minimize the impact of deactivation.

Published: November 2023

Gram-negative bacterium Acinetobacter sp. Tol 5 exhibits high adhesiveness to various surfaces of general materials, from hydrophobic plastics to hydrophilic glass and metals, via AtaA, an Acinetobacter trimeric autotransporter adhesin (TAA). Although the adhesion of Tol 5 is nonspecific, Tol 5 cells may have prefer materials for adhesion. Here, we examined the adhesion of Tol 5 and other bacteria expressing different TAAs to various materials, including antiadhesive surfaces. The results highlighted the stickiness of Tol 5 through the action of AtaA, which enabled Tol 5 cells to adhere even to antiadhesive materials, including polytetrafluoroethylene with a low surface free energy, a hydrophilic polymer brush with steric hindrance, and mica with an ultrasmooth surface. Single-cell force spectroscopy as an atomic force microscopy technique revealed the strong cell adhesion force of Tol 5 to these antiadhesive materials. Nevertheless, Tol 5 cells showed a weak adhesion force toward a zwitterionic 2-methacryloyloxyethyl-phosphorylcholine (MPC) polymer-coated surface. Dynamic flow chamber experiments revealed that Tol 5 cells, once attached to the MPC polymer-coated surface, were exfoliated by weak shear stress. The underlying adhesive mechanism was presumed to involve exchangeable, weakly bound water molecules. Our results will contribute to the understanding and control of bacterial cell adhesion to material surfaces.
Synergy of Machine Learning and Density Functional Theory Calculations for Predicting Experimental Lewis Base Affinity and Lewis Polybase Binding Atoms
Authors: Huynh Hieu , Le Khanh , Vu Linh , Nguyen Trang , Holcomb Matthew , Forli Stefano , Phan Hung
Published: November 2023

Investigation of Lewis acid-base interactions has been conducted by ab initio calculations and Machine Learning (ML) models. This study aims to resolve two critical tasks that have not been quantitatively investigated. First, ML models developed from Density Functional Theory (DFT) calculations predict experimental BF3 affinity with Pearson correlation coefficients around 0.9 and mean absolute errors around 10 kJ mol-1. The ML models are trained by DFT-calculated BF3 affinity of more than 3000 adducts, with input features readily obtained by rdkit. Second, the ML models have the capability of predicting the relative strength of Lewis base binding atoms in Lewis polybases, which is either an extremely challenging task to conduct experimentally or a computationally expensive task for ab initio methods. The study demonstrates and solidifies the potential of combining DFT calculations and ML models to predict experimental properties, especially those that are scarce and impractical to empirically acquire.
7-Oxa-2,3-diazanorbornene: A One-Step Accessible Monomer for Living ROMP to Produce Backbone-Biodegradable Polymers
Authors: Wang Xiaoyang , Wen Yixing , Wang Yu , Li Wei , Lu Xueguang , You Wei
Published: November 2023

Traditional ring-opening metathesis polymerization (ROMP) reactions exhibit broad functional group compatibility and precise control over polymer architectures, albeit with non-biodegradable backbones. Recent progress has resulted in a series of biode-gradable ROMP products with diverse cleavable functional groups, yet the majority of the monomers display moderate to low ring strain, which restricts their living polymerization reactivity. In this study, a novel category of readily available 7-oxa-2,3-diazanorbornenes (ODAN) is presented, which exhibits the highest ring strain (22.8 kcal/mol) compared to existing degradable ROMP monomers. This trait endows ODAN with the ability to perform living polymerization reactions, generating narrowly dis-persed homopolymers, block copolymers, and statistical copolymers with various cyclic olefin comonomers, thereby enabling pre-cise control over distribution of the biodegradable functional groups. Additionally, the resultant polymers comprise directly con-nected allyl hemiaminal ether and urethane units, which are hydrolysable at controllable rates. Thus, these well-defined, structure-tunable, and backbone-biodegradable ROMP polymers are applied as nano-etching materials and biodegradable delivery carriers.

Authors: Wu Yingtao , Li Mingrui , Sun Jiaqiong , Zheng Guangfan , Zhang Qian
Published: November 2023

Axially chiral diaryl ethers bearing two potential axes found unique applications in bioactive molecules. However, only very few catalytic methods have been developed to construct structurally diverse diaryl ethers. We herein describe an NHC-catalyzed atroposelective esterification of biaryl dialdehydes leading to the synthesis of flexible axially chiral diaryl ethers. Mechanistic studies indicate that coupling proceeds through NHC-catalyzed desymmetrization of the dialdehydes and matched kinetic resolution. This protocol features excellent enantioselectivity, mild conditions, good functional-group tolerance, and applicability to late-stage functionalization and provides a modular platform for the synthesis of axially chiral diaryl ethers. and their derivatives.
Ni0(cod)(dq) (COD: 1,5-cycloctadiene; DQ: duroquinone) complex as a catalyst precursor for oligothiophene and polythiophene synth
Authors: Noda Naoki , Yamaoka Seiha , Ogi Ukyo , Horie Masaki , Okano Kentaro , Mori Atsunori
Published: November 2023

Nickel-catalyzed syntheses of oligothiophene and polythiophene were carried out with Ni(cod)(dq) (COD: 1,5-cycloctadiene; DQ: duroquinone) as a catalyst precursor. Studies on ligand exchange of Ni(cod)(dq) revealed that a high temperature was necessary to replace COD and DQ with PPh3 and N-heterocyclic carbene IPr. A coupling reaction of a meta-lated 3-hexylthiophene with 2-chloro-3-hexylthiophene employing Ni(cod)(dq) with IPr proceeded with a remarkably re-duced amount of homocoupling byproduct. Polymerization of 2-chloro-3-hexylthiophene with Ni(cod)(dq)/DPPP also re-sulted to reduce the regioregularity defect.

Channel Power, Influence Strategy, Relationship Continuity, and Channel Performance: An Examination of Sanitary Equipment Manufacturers
Authors: Yen Wen-Hong , Wu Chun-Kuang , LI Peng-Yu
Published: November 2023

Purpose: This study aims to examine the influence of channel power and influence strategy, in terms of non-coercive strategies, on sanitary equipment manufacturers' relationships with channel members and channel performance.
 
Theoretical framework: The study is based on the literature on channel relationships, which suggests that using an influence strategy can contribute to managing the relationship with the channel members and benefit organization performance.
 
Design/Methodology/Approach:  In this study, we sampled from a sanitary equipment manufacturer's channel strategy. We used survey data to examine the effect of channel management strategies from sanitary equipment manufacturers on distributors.
 
Findings: The finding indicates that a supplier using economic power tends to adopt non-coercive strategies. In addition, economic power and non-coercive strategies positively affect the continuity of the relationship with distributors. Relationship continuity between manufacturers and distributors positively impacts whole channel performance.
 
Originality/Value: This study sampled the distributors in the sanitary equipment industry, a market in which the consumers are not knowledgeable about the products. Most consumers base their purchase decisions heavily on the channel member’s recommendations. Therefore, how to manage the relationship with the channel members is critical to understand.
 
Research, Practical & Social implications: Distributors are regarded as an extension of the company's sales capabilities. Channels have always held an essential position in the industry. Maintaining relationships between distributors and improving channel performance is a critical question in distribution management.
Estudo dos Fatores Explicativos do tipo de Opinião Emitida pelo Auditor nos Municípios Portugueses de Média Dimensão
Authors: Dos Santos Paula Gomes , Martinho Carla , Pinho Carlos , Lopes Raquel
Published: November 2023

Objetivo: O objetivo deste estudo foi estudar os fatores explicativos do tipo de opinião, emitida pelo auditor, nos municípios portugueses de média dimensão, no período de 2016 a 2018.

 

Referencial teórico: A literatura tem relatado que a opinião emitida no relatório de auditoria é afetada por diversos fatores (Ferreira & Morais, 2019). No entanto, ainda há muito o que investigar e aprender sobre quais são estes fatores no âmbito do setor público.

 

Desenho/metodologia/abordagem: Analisamos as certificações legais de contas de 2016 a 2018, identificando os diversos tipos de opinião emitidos. Estudou-se, ainda, através de análise de regressão logística os fatores que explicam a emissão daquela opinião.

 

Resultados: A emissão de anteriores opiniões modificadas demonstra ser estatisticamente significativa para a emissão de opiniões modificadas nos municípios portugueses de média dimensão, o que se considera ser especialmente relevante dado que as entidades parecem ter uma tendência para reportar informação financeira com limitações, não demonstrando capacidade de ultrapassar as situações apontadas pelo auditor que lhes permita divulgar informação mais transparente e que contribua para uma verdadeira accountability da governação pública.

 

Pesquisa, implicações práticas e sociais: Contribui para que os governos, auditores e entidades reguladoras compreendam o que motiva o relato de informação de menor qualidade por parte destes municípios. Apesar do estudo assentar nos de média dimensão, estas pistas poderão ser úteis para as restantes dimensões e, inclusive, para outros subsetores públicos.

 

Originalidade/valor: Contribui para colmatar uma lacuna na literatura no que respeita ao conhecimento dos fatores explicativos do tipo de opinião emitida pelo auditor no âmbito do setor público.

Authors: Sousa Oliveira Vitoria , Marmanillo Pereira Jesus
Published: November 2023

Partindo da hipótese de que a produção de imagens caracteriza uma importante etapa que marca os processos de institucionalização e sociabilidade ligados ao skate, na cidade de Imperatriz-MA, o presente artigo toma a produção e circulação imagética para compreender e analisar aspectos sociotécnicos presentes na formação de três importantes coletivos locais. Para tanto, nos valemos dos estudos de Mauss (2003), autor que oferece importantes contribuições tanto nos estudos da técnica quanto nos das emoções, Simmel (2006) que nos possibilitou valorizar o aspecto da sociabilidade e assim por diante como Giancarlo (2012), Pereira (2019) entre outros mais especializados no tema do skate. Portanto, nas conclusões preliminares, observamos a importância da produção de imagens nos processos de institucionalização dessa prática urbana, como forma de expressão de determinadas técnicas e usos das emoções nos processos associativos que caracterizam os coletivos locais de skate.
Confianza, miedo y pragmatismo. Sobre las experiencias personales de vacunación contra el COVID-19
Authors: Moguillansky Marina , Fischer Melina
Published: November 2023

Las campañas de vacunación contra el COVID-19 fueron una inflexión en el desarrollo de la pandemia, llevando a una disminución de los casos graves y de las muertes que a su vez derivó en una situación de endemia. No obstante, su implementación no estuvo exenta de discusiones y conflictos políticos con alta visibilidad mediática. Este artículo analiza, a partir del caso argentino, el proceso de decidir aplicarse la vacuna contra el covid-19, a nivel personal y subjetivo, desde la perspectiva de la sociología y la antropología de las emociones. Desde un abordaje cualitativo, basado en entrevistas en profundidad, se analizan las creencias y los repertorios emocionales asociados con la decisión de vacunarse en dos grupos de actores: por un lado, quienes presenta su experiencia con las vacunas como satisfactoria y asociada a la confianza y la tranquilidad, y por el otro, quienes a pesar de tener dudas y miedos, decidieron vacunarse.
Capital erótico e trabalho emocional no cotidiano de promotoras de eventos: notas teóricas
Authors: Cavalcante Alves Iáscara Gislâne , Costa Jean Henrique , Barbosa Raoni Borges
Published: November 2023

Este ensaio buscou compreender como o capital erótico e o trabalho emocional operam no cotidiano profissional de promotoras de eventos. Nesse sentido, a reflexão sobre as implicações teóricas destes conceitos objetivou examinar criticamente o Mito da Beleza criado nos mercados de eventos, bem como apontar a violência simbólica que as mulheres trabalhadoras aí vivenciam. O mercado de eventos, com efeito, caracteriza-se por ser extremamente absorvente de mulheres jovens e extremamente seletivo em relação à contratação e adestramento de corpos e comportamentos tidos como fachada pública de valor comercial pelo que a trabalhadora agrega à empresa. Com base no levantamento bibliográfico e nas discussões até então realizadas, o ensaio aponta que a pressão sobre e entre as mulheres no jogo simbólico-interacional do trabalho estruturalmente organizado pelos ditames do Capital é intensa graças a uma configuração social e cultural que insiste em enxergá-las como objeto ou como uma figura submissa que deve ser capaz de reproduzir o que lhes é ordenado sem jamais reagir ou questionar. Pressão esta que se manifesta como exercício de envergonhamento sobre corpos indesejáveis e de imposição de conduta sobre corpos desejados.
Study of the effect of the morphology of initial powders on the structural and dimensional characteristics of SiC-based porous ceramic materials

Published: November 2023

The realization of the necessary energy-efficient technological solutions for the production of highly porous SiC-ceramic materials requires appropriate research. The results of developing energy-efficient one-step methods for the synthesis of porous SiC-based ceramics and studying the characteristics of the obtained ceramics are presented. The effect of the morphology of initial powders on the synthesized product is considered. Ultrafine silicon carbide powders of two types, identical in characteristic particle size, but quite different in the surface morphology, were used as fillers in the synthesis of experimental samples of porous ceramics. The first one was obtained by the traditional furnace method (SiCf), the second one was synthesized by the technology of self-propagating high-temperature synthesis (SiCshs). It is shown that the particle morphology of initial powder components determines the structural parameters and characteristics of synthesized porous ceramics. The pore space parameters (average pore size, specific surface area, equivalent hydraulic diameter, permeability, etc.) can vary significantly. Porous ceramic materials synthesized on the basis of SiCf have an open porosity of 47%, high liquid permeability (up to 2 mDarcy), overwhelming dominance of α-SiC phase, and a narrow pore distribution with an average pore size of about 1 μm. High open porosity (more than 58 %), highly developed nanostructured pore space surface with an area of more than 12 m2/g, and wider pore size distribution (average pore size — 140 nm) are observed in porous ceramic materials based on SiCshs. The obtained results can be used to improve energy-efficient synthesis technologies and methods for predicting the properties of highly porous SiC-based ceramic materials. This will make it possible to create highly porous SiC ceramics within a priory predicted limits of effective applicability for the processes of ultrafiltration or catalysis.

Published: November 2023

The effect of additives of Ti2NbAl intermetallic compound on the friction of B83 babbitt samples obtained by hot pressing was studied using optical, electron microscopy and EDS analysis. The structure, friction surface and wear products were studied. Tribological tests were carried out on a universal test system under conditions of dry sliding friction according to the scheme of axial loading: a steel bush against a disk of the material under study. The temperature values near the friction zone were recorded. The limits of application of the material depend on the mode and mechanism of wear occurring in the tribocontact. Changes in the mode and mechanism of wear were assessed by differences in the behavior of the friction coefficient, temperature, difference in the state of friction surfaces, wear intensity and wear products. The results obtained indicate the prospects of using the method of hot pressing of powder from the B83 alloy and discrete particles of the high-strength Ti2NbAl intermetallic phase to get composite materials with improved tribological properties compared to a babbitt alloy. The introduction of reinforcing high-modulus particles of intermetallic compounds changed the structure of the material and affected the friction processes in babbitt, pushing aside the onset of change in the mode of wear towards more severe friction conditions. A significant decrease in the wear intensity of babbitt-based composite materials compared to the original alloy makes it possible to predict an increase in the service life of tribo-units. The data obtained enable us to determine and recommend modes that improve the performance of tribo-nodes in the manufacture of both volumetric inserts and plain bearings made of B83 alloy and, moreover, to create new functionally organized layered compositions with enhanced tribotechnical properties with a base of structural steels and working surface layers not only using B83 babbitt, but also of composite materials based on B83 babbitt.
Influence of the degree of saturation and the wetting front on the stability of cliffs: a case study on a cliff located on the beach of Tabatinga-RN-Brazil

Published: November 2023

Coastal zones are of great interest in civil engineering due to their economic relevance and active geological dynamics. In Brazil, the development of these regions is related to the use of their geomorphological features in the landscape, among which the cliffs stand out. Although there are studies that consider the influence of the wetting front in stability analysis with cliffs, in general, the studies only consider extreme saturation situations (dry and saturated). In this sense, the present study aims to understand the influence of the wetting front and the degree of saturation reached by the materials in the stability of cliffs composed of Barreiras Formation soil. The stability analyses were carried out using the limit equilibrium method and stress analysis, varying the degrees of saturation of the materials and wetting fronts of a model of a cliff located at Praia de Tabatinga, State of Rio Grande do Norte, Brazil. Failures were identified, in different wetting fronts, by the limit equilibrium method from degrees of saturation around 20%, and by the stress analysis method around 40%. Thus, it was concluded that the variation in the degree of saturation has a preponderant effect on the destabilization of a cliff, since partial saturations are already enough to trigger significant mass movements. It was also noticeable that the wetting front is a relevant effect on instability, although conditioned to the degree of saturation reached, which may enhance the order of magnitude of the identified failures.
Optimizing Reproductive Health Capacity: A P-Process and CBR Approach in Karang Taruna Tambak Sumur Sidoarjo
Authors: Eko Teguh Pribadi  , L Sri Hidayati
Published: November 2023

Adolescent Reproductive Health (ARH) remains a behaviorally-based health issue prioritized by government interventions, with the principal determinants being a lack of information and education on reproductive health, shifts in adolescent behavior, inadequate health services, and unsupportive regulations. The community service conducted in Tambaksumur Village, Sidoarjo District in 2023, was structured around the integration of the P-Process model and Community Based Research (CBR) aimed at enhancing adolescents' knowledge and attitudes related to ARH, and at formulating approaches for internalizing the functions of health promotion and education within the Karang Taruna organization. The service outcomes indicated that through peer-education activities, there were significant differences in the knowledge and attitudes of the targeted adolescent group before and after the intervention, with 2-tailed significance values of 0.010 (knowledge) and 0.020 (attitude). The sustainability of Karang Taruna's ARH-focused programs can be maintained through the integration of the Adolescent Posyandu program with Karang Taruna, coupled with continuous support and guidance from health academics.

Influence of Ho Substitution on Structural, Morphological, and Optical Properties of Anatase Ti1-xHoxO2 (x= 0.0, 0.01, 0.02, 0.03) Thin Films
Authors: KAYA Şeydanur
Published: November 2023

Ti1-xHoxO2 (x= 0.0, 0.01, 0.02, 0.03) thin films are synthesized by a sol-gel method and deposited by a dip-coating technique on the glass substrates. The films’ crystal structures are examined by an X-ray diffraction technique, while the morphological properties are investigated by scanning electron microscopy and atomic force microscopy. UV-Vis and photoluminescence spectrophotometry are used to analyze the optical properties. Based on the X-ray diffraction patterns, all the films belong to the anatase phase. It is observed that the surface characteristics, such as the morphology, film thickness, and roughness change significantly with the holmium substitution. The optical investigations reveal that the transmittance, band gap energies, and luminescence properties can be adjusted by the holmium substitution. According to the current study, holmium substituted TiO2 thin films with improved optical properties may be a suitable candidate for applications that require a wide band gap and high optical transparency as well as luminescence properties.

Published: November 2023

We started this work with a theorem that shows in which case the abbreviation rule for neutrosophic real numbers is true. We then detail in which cases the division of two neutrosophic real numbers yields a new neutrosophic number. Then, the solution cases of a neutrosophic linear equation with one unknown were examined. After calculating the determinant of a square matrix and giving the necessary and sufficient conditions for a square matrix to be invertible, the solution conditions of the systems of equations with the number of unknowns equal to the number of equations were examined.

According to the RSM results, it was determined that the experimental design fit the quadratic model, and the R2 and R2adj values, which are the parameters showing the model fit, were 0.98 and 0.95, respectively. HDTMA-Volk at optimum conditions. Adsorption capacity was obtained as 4.41 mg/g for the HDTMA-Volcanics at optimum conditions. The compatibility of the obtained data with adsorption isotherms was investigated, and thermodynamic parameters were calculated.
Investigation of the incorporation of C60 into PC61BM to enhance the photovoltaic performance of inverted-type perovskite solar cells based on MAPbI3
Authors: KAZICI Mehmet
Published: November 2023

Perovskite Solar Cells (PSCs) have managed to significantly capture attention by achieving efficiency values of 25.6% in a remarkably short period of around ten years. Each layer within the device plays a crucial role in the overall device efficiency when it comes to PSC production. PC61BM, a derivative of fullerene, is one of the most commonly used electron-transport layers (ETLs) in inverted-type PSCs. In this study, the improvement of the ETL was aimed by incorporating C60 into PC61BM, and the effects of the doped ETL on MAPbI3-based inverted-type PSCs were investigated. For inverted type PSCs which are fabricated under high humidity (40-60%) and room conditions (~25 °C), the power conversion efficiencies (PCEs) have boosted from 11.54% (for undoped PC61BM) to 13.40% (for C60-doped PC61BM). To comprehend the sources of improvement in the fabricated devices, a series of characterizations were carried out, including Current Density-Voltage (J-V), Hysteresis Factor (HF), Scanning Electron Microscope (SEM), and Atomic Force Microscope (AFM) measurements.
