Authors: Rusli Dodi Yarli , Azka Aulia
Published: August 2024

Penelitian ini bertujuan untuk mengetahui bagaimana penyelesaian sengketa waris dengan jalan damai (ash-shulhu) melalui Bale Mediasi dan bagaimana jika ditinjau dari perspektif maqashid syariah. Metode yang digunakan adalah kualitatif dengan jenis penelitian hukum empiris. Data dalam penelitian ini didapatkan melalui wawancara dan studi pustaka. Hasil dari penelitian ini adalah penyelesaian sengketa waris dengan jalan damai (ash-shulhu) melalui Bale Mediasi tidak mengikuti aturan waris Islam. Para mediator telah menjelaskan tentang pembagian waris sesuai syariat kepada para pihak sebagai ahli waris, namun mereka sepakat berdamai dengan keputusan hasil musyawarah. Hasil akhir dari mediasi ini adalah terciptanyanya surat tertulis, yaitu surat kesepakatan perdamaian sebagai alat bukti yang sah. Bale Mediasi mengimplementasikan 4 (empat) aspek maqashid syariah dalam penyelesian sengketa waris dengan jalan damai (ash-shulhu) yaitu menjaga agama (hifdzu din), menjaga jiwa (hifdzu nafs), menjaga akal (hifdzu aql) dan menjaga harta (hifdzu mal).

On some theories of oncogenesis
Authors: Robert Jacques
Published: August 2024

A large number of theories have been proposed for explain the origin of cancers. Although we still face several off-the-wall hypotheses, the somatic mutation theory, elaborated almost 50 years ago, remains the masterpiece allowing us to understand where do cancers come from and how they progress in humans.
Existence of Halos Outside Schwarzschild-f(R) Black Holes
Authors: Chen Wen-Xiang
Published: August 2024

In this paper, we investigate the possibility of the existence of halos around Schwarzschild-f(R) black holes by analyzing the null geodesics of photons in the spacetime. Using a method inspired by the analysis of spherical photon orbits around Kerr-Newman black holes, we explore the conditions under which such halos might exist. Our results suggest that under certain forms of f(R) gravity, halos can indeed form outside the event horizon, providing new insights into the geometry and observational properties of these modified black holes.

Authors: Meza Steven Darío Menéndez , Zambrano Cintya Maribel Zambrano , Villafuerte-Holguín Jhonny
Published: August 2024

This study investigates an innovative teaching methodology that combines suggestopedia, digital resources, and experimental and control groups to improve reading-writing English skills. The methodology integrates relaxation and visualization techniques of suggestopedia with engaging digital tools to create a stimulating learning environment. A pre-test established a baseline, and the innovative approach was implemented over several weeks, with lessons integrating suggestopedia and digital resources like multimedia presentations and online reading-writing platforms. A post-test showed statistically significant improvements in students' writing performance. Focus group discussions revealed that students found the lessons engaging, confidence-boosting, and effective in enhancing their reading and writing abilities, particularly appreciating the relaxed atmosphere of suggestopedia and the interactive nature of the digital tools. The study demonstrates the potential of this innovative approach to enhance English writing skills and foster a positive learning experience, warranting further research on its long-term effects and applications in diverse educational contexts.

Authors: Winata Robbie Kurniawan , Soekarno Subiakto
Published: August 2024

The purpose of this study is to summarize research on digitalization and emphasize how it affects financial performance. Additionally, applicable methodology from recent studies in a variety of domains is shown in this study. The state-of-the-art in digitalization research is described in this review article, which combines technology, finance, marketing, and innovation literature. In recent years, research on digitalization has expanded rapidly in a number of domains, employing both qualitative and quantitative techniques. The elements that affect an organization’s financial performance as a result of its digitalization—such as big data analytics, cloud computing, artificial intelligence, process automation, the Internet of Things (IoT), computer simulations, and online technology—have been the subject of more recent studies. Even if studies on digitalization have been more popular over the past five years, adding new dimensions and investigating qualitative methods remain fascinating areas of study. For academics who are unfamiliar with digitalization, this article provides an overview of how to explore the process. The article enhances the review of the impact of digitization on financial performance.
Changes in life expectancy by household type: the case of Denmark between 2019 and 2021
Authors: Vigezzi Serena , Strozza Cosmo , Zarulli Virginia
Published: August 2024

Contrary to other countries, Denmark did not experience mortality declines in 2020, but did in 2021. At the same time, COVID-19 has been shown to unequally affect different population groups. Among other characteristics, living arrangements were hypothesised to influence infection and mortality risk. We use Danish data (from registries and Ministry of Health) to compute life expectancy at ages 30 and 60 by gender and household type. We compare the average yearly change between 2015 and 2019 with changes in life expectancy between 2019 and 2021 together and for each year, using bootstrapping to create 95% confidence intervals. Finally, we decompose changes in life expectancy by age and cause of death. In most subgroups, life expectancy did not decline in 2020, and even improved for nursing home residents, who suffered greatly in other countries. There were declines in 2021, but only men and women in complex households and women in nursing homes experienced overall losses between 2019 and 2021. These changes were partially driven by COVID-19 mortality, but mostly by mortality by other causes. In 2020, Denmark managed to protect its population from the mortality effects of the pandemic, even improving mortality by non-COVID-19 causes. In contrast, in 2021 there was a lagged effect on mortality due to non-COVID-19 causes of death, which considerably increased, and thereby reduced life expectancy across subgroups.
Instruments for Dual-Factor Mental Health Screening in Elementary Schools Implications in Mental Health Classification
Authors: Chan Mei-ki , Furlong Michael , Ruff Emmy
Published: August 2024

This research study holds practical significance for educators, school administrators, and mental health professionals. The study utilized structural equation modeling on two samples of elementary school students in grades three to five to create and validate condensed versions of the Social-Emotional Health Survey-Primary and the Me and My School questionnaire. These abbreviated scales exhibited strong internal validity and reliability across grade levels and genders, allowing for the assessment of wellness and distress among a diverse range of elementary school students. Furthermore, data from a longitudinal sample investigated dual-factor mental health profiles and their consistency over one year. Based on the newly validated scales, the wellness and distress indicators revealed three distinct profiles: Flourishing, Moderate, and Languishing. The transitions of students across these profiles emphasize the importance of routine mental health screening, at least once annually, to identify and address students’ needs.
Operationalization of Affective Polarization in Multiparty Systems
Authors: Torcal Mariano , Comellas Bonsfills Josep Maria
Published: August 2024

This chapter delves into the complexities of measuring affective polarization (AP) in multiparty systems, extending research from the U.S. to more diverse party settings. It highlights the challenges of adapting measures like the feeling thermometer to such contexts, where individuals may have nuanced feelings towards multiple parties. Existing indices like the affective polarization index (API) and weighted mean distance from the most-liked party (Distance) encounter difficulties in capturing the intricate dynamics of AP in multiparty systems. The chapter proposes a new measure that integrates Social Identity Theory (SIT) into the measurement of AP. This approach aims to capture genuine affective ties and hostilities, avoiding instrumental considerations. Preliminary validation of the new measure is conducted using survey data from Spain.
Do spatial processes support transitive reasoning in depression and sad mood?
Authors: Arjmandi Zahra , von Hecker Ulrich , Fazilat-Pour Masoud
Published: August 2024

People in states of mild depression have difficulties in reasoning tasks that demand the flexible integration of piecemeal information into mental representations. Previous research found inferior performance levels in depressed participants compared to nondepressed controls when constructing mental models of linear orders (LOC task). The present research investigates whether depressed individuals show evidence for reduced functionality of spatial processes during LOC execution. We tested three groups of participants in an LOC task: Nondepressed controls, mildly depressed, and episodically sad controls (via mood manipulation). We found spatial processes to be involved in model construction for the control group, in a magnitude as previously reported for similar tasks. However, both depressed and sad groups showed evidence for the absence of spatial processes being part of their reasoning in this task. These results are discussed in the context of cognitive and neurophysiological theories about depressed participants’ performance impairments when it comes to reason spatially, reliably construct mental representations from piecemeal information and flexibly reason on the basis of them. We also relate the results in the episodically sad group within the context of parallel cognitive marker symptoms in sadness and mild depression.
Childhood obesity trajectories and adolescent mental health: A UK cohort study
Authors: Putra I Gusti Ngurah Edi , Daly Michael , Robinson Eric
Published: August 2024

Background: We examined how obesity trajectories and time living with obesity during childhood predict mental health at age 17. Methods: Data were from the UK Millennium Cohort Study. Obesity trajectory groups between ages 7 and 17 (n=8,306) and previous obesity episodes from ages 7, 11, and 14 (n=7,246) were examined. Caregiver-reported internalising and externalising symptoms at age 17 were assessed. Linear regression models were used.Results: Obesity development and persistence (vs. never developing obesity) were associated with worse internalising symptoms at age 17, and worsening trajectory of these symptoms between age 7 and 17. Evidence of worse externalising symptoms at age 17 and a worsening trajectory of these symptoms over time only appeared for obesity development (vs. never developing obesity). Obesity reversal (vs. never developing obesity) by age 17 was not associated with worsening mental health. Having multiple episodes of obesity in the past was not associated with worsening mental health in individuals with and without current obesity at age 17.Conclusions: Development and persistence of obesity from ages 7-17 are associated with worsening mental health. If childhood obesity is reversed, there appears to be no evidence of a negative effect of previous obesity on mental health at age 17.
The Relations Among Anxiety, Movie-Watching, and In-Scanner Motion

Published: August 2024

Movie-watching fMRI has emerged as a theoretically viable platform for studying neurobiological substrates of affective states and emotional disorders such as pathological anxiety. However, using anxiety-inducing movie clips to probe relevant states impacted by psychopathology could risk exacerbating in-scanner movement, decreasing signal quality/quantity and thus statistical power. This could be especially problematic in target populations such as children who typically move more in the scanner. Consequently, we assessed: 1) the extent to which an anxiety-inducing movie clip altered in-scanner data quality (movement, censoring, and DVARS) in a pediatric sample with and without anxiety disorders (n=78); and 2) investigated interactions between anxiety symptoms and movie-attenuated motion in a highly powered, transdiagnostic pediatric sample (n=2058). Our results suggest anxiogenic movie-watching in fact reduces in-scanner movement compared to resting-state, increasing the quantity/quality of data. In one measure, pathological anxiety appeared to impact movie-attenuated motion, but the effect was small. Given potential boosts to data quality, future developmental neuroimaging studies of anxiety may benefit from the use of movie paradigms.
Negative Spillover Effects of Opt-out Defaults: Evidence from Organ Donation Policies
Authors: Güntürkün Pascal , Studte Sinika , Winkler Daniel , Clement Michel , Merz Eva-Maria , Tan Jonathan , Huis in 't Veld Elisabeth , Ferguson Eamonn
Published: August 2024

Many of today’s pressing societal challenges, such as the shortage of organs for transplantation, low vaccination rates, or the progression of climate change, require significant changes in individual behavior. One promising intervention to encourage such behavioral change is the opt-out default, which presumes consent to a desirable behavior rather than relying on people to actively opt in. However, past research mainly studied how opt-out defaults affect the targeted behavior but largely omitted the possibility of negative spillover effects on related behaviors. Here, we study the possibility of such negative spillover effects on living organ donation (the related behavior) when countries switch to opt-out organ donation targeted at deceased donation. Analyzing epidemiological panel data from countries that switched to an opt-out default between 2000 and 2019, we show that switching to an opt-out default policy, on average, increased deceased organ donors by 2.79 per million population (pmp)––i.e., a relative uplift of +18% in the targeted behavior––but also decreased living organ donors by -3.56 pmp––i.e., a relative drop of -62% in a related behavior––resulting in an overall net-zero effect. Using a comparative country survey and experiment, we demonstrate that this reduced willingness for living altruistic (vs. familial) donations is attributable to people being less willing to become a living donor because they hold stronger beliefs that the organ supply is sufficiently met under opt-out (vs. opt-in). Our research advances insights into the unintended consequences of default nudges and offers initial suggestions on how to overcome negative spillover effects.
Neurocomputational Models of Task Representation
Authors: Freund Michael Crawley , Braver Todd Samuel
Published: August 2024

Human cognition is purposive. We can set our minds toward attaining a particular desired goal, ignoring distractions and overriding counterproductive habits. Yet, it is also multipurpose. We are not permanently bound to pursue a singular goal, or even a small number. As drives and circumstances change, we can flexibly set our minds to attaining more suitable ones. How does the brain achieve this “setting” and “resetting” — this capacity for cognitive control?Increasingly, cognitive neuroscientists are focusing on studying representations that underlie cognitive control, formalizing their ideas within neurocomputational models (Botvinick and Cohen, 2014). Two distinct models of task representations have been highly influential: Guided Activation (Miller and Cohen, 2001), and Adaptive Coding (Duncan, 2001) through Random Mixed Selectivity (Rigotti et al., 2013). While these models have several commonalities --- both posit that the prefrontal cortex (PFC) drives controlled behavior through task representations --- they differ greatly in the representations they posit, and more generally reflect discrepant philosophies of understanding brain function.Here, we provide an overview of cognitive research into cognitive control, focusing on the role of task representations. A detailed examination of the Guided Activation and Adaptive Coding or Random Mixed Selectivity models is provided, in which models are evaluated in relation to the extant experimental literature and compared with respect to broader issues regarding task representations.
Psychosocial factors and the development of childhood overweight and obesity: A UK cohort study
Authors: Putra I Gusti Ngurah Edi , Daly Michael , Robinson Eric
Published: August 2024

Background: We examined the role of psychosocial factors in overweight and obesity development. Methods: UK Millennium Cohort Study data of children with normal weight were analysed. Weight changes were determined from baselines at ages 11 (n=7,979) and 14 (n=6,906) to follow-up at age 17. Baseline individual psychosocial factors were combined into two distinct indexes (caregiver-reported child mental health, child-reported psychosocial well-being). Regression models examined the associations between baseline indexes and individual psychosocial factors and overweight and obesity development (vs. no) and body mass index (BMI) z-score changes. Results: Worse child mental health, but not psychosocial well-being, at age 11 was associated with overweight and obesity development (OR=1.14;95%CI=1.02,1.27) and increased BMI z-scores (β=0.08;95%CI=0.04,0.12) to age 17. No psychosocial indexes at age 14 predicted the outcomes. Further analyses showed that child mental health at ages 11 vs. 14 was more likely to predict the outcomes. Based on individual factors, externalising symptoms and experiencing peer bullying at age 11 may be important contributors to overweight and obesity development. Conclusions: Poor child mental health at age 11 is associated with overweight and obesity development by age 17. Late childhood/early adolescence may be a sensitive period in which psychosocial factors determine body weight trajectories.
Examining the effectiveness of mindfulness interventions for anxiety in young adults: a narrative synthesis
Authors: Bose Joy
Published: August 2024

BackgroundAnxiety disorders, such as generalized anxiety disorder and social anxiety, are a major problem among adolescents and young adults. Structured mindfulness based interventions such as Mindfulness Based Cognitive Therapy (MBCT) and Mindfulness Based Stress Reduction (MBSR) have been shown to be at least as effective as other interventions for treating anxiety, but a thorough analysis of different factors for effective treatments is missing.ObjectiveThe objective of this narrative synthesis is to synthesize mindfulness treatments for anxiety in young adults aged between 12 to 25, and examine components of those interventions that are more effective in reducing anxiety. MethodsStudies were selected from 3 public databases (APA Psycinfo, Embase, Medline), as well as a manual process to augment the searches. Interventions involving Mindfulness based Cognitive Therapy (MBCT) and Mindfulness based Stress Reduction (MBSR) based studies, as well as their variants were eligible. Anxiety should be one of the measures in the study although it may not be the primary measure. After initial screening and removal of duplicates, 8 studies involving 423 participants were identified. ResultsIdentified themes included customizations for young people, homework and follow ups, qualifications of the instructors, dropout rates, physical activity and subjective experience. Most studies showed a significant decrease in anxiety symptoms, in case of social phobia, chronic pain, stress and academic performance. However, variable scales for measuring anxiety were employed across studies, making it difficult to combine or compare them. The amount of improvement of anxiety was variable. Interventions that included mindfulness information sessions for parents and interventions with mindful physical activity such as yoga showed better results. ConclusionRecommendations are presented to enable more effective mindfulness interventions tailored for young people with anxiety. Keywords: Mindfulness, generalized anxiety disorder, chronic pain, academic performance, social anxiety, stress, mindfulness based stress reduction, mindfulness based cognitive therapy, adolescents, young people, young adults

Published: August 2024

The life of fisherman is always synonymous with poverty. There are many causes of poverty in the life of fisherman, such as, the lack of access to capital sources, access to technology, access to market and low participation of the community in the management of natural resources. Social stratification and capital penetration among fishermen also cause poverty and conflict potential among them becomes more complicated. This study analyses interrelation pattern among fishermen in the context of social stratification and identifies adaptation strategies of traditional fishermen in dealing with problem of fish catching and surviving in the middle of environmental change in their region. The objective of this study is to formulate the right pattern to eliminate conflict potential among level of fishermen and to recommend the right poverty alleviation model to develop in their region.This study uses mixing method approach by combining descriptive quantitative approach and qualitative approach as well as participatory approach. The target of this study is “laut” tribe fishermen in Panglima Raja village (Concong luar), community figures, village government officer and sub district government officer in Indragiri Hilir regency. Collected data will be analyzed with interactive analysis model.Research result shows that the low selling value and catching result of fishermen are caused by the limit of technology and high cost fare that make traditional fishermen are still struggling with poverty. The low human resources quality of traditional fishermen has implication to all sides of fishermen’s life especially adaptation ability to the changes in aquatic ecosystems. Therefore, the efforts of community empowerment through education actualization, allignments on marginal fishermen communities and government commitment need to get attention.

A Comparative Study on the Notion of Alienation in Buddhist and Existential Philosophy
Authors: Chow Samching Manhai
Published: August 2024

The issue of alienation arises when subject and object are confused in today's environment. Significant advances in science and technology have given rise to this problem. The concept of alienation was clarified in modern times by philosophers like Karl Marx and Hegel. The idea was later investigated in greater detail in the twentieth century by the schools of phenomenology and existentialism, which featured theorists like Martin Heidegger and Jean-Paul Sartre. Many authors have discussed alienation in their works. Buddhism and existentialism have recently raised awareness to this problem. Existentialism and Buddhism both address comparable questions about life, even if they developed in separate historical periods and with distinct approaches. In existentialism, the dissociation of humans from their own existence or identities is referred to as alienation. Individuals reflect on themselves as the lost things among the crowd. A feeling of meaninglessness is brought about by life events like boredom and anxiety. Buddhism views the issue of estrangement as a means of comprehending human suffering. To end life’s suffering, one must identify its source. The three main causes of suffering in life—craving, hatred, and ignorance—have been discovered by the Buddha. He has also discovered the three roots of happiness in life, which are non-ignorance, non-hatred, and non-greed, in opposition to these three factors. These two philosophies aim to liberate people from all forms of enslavement. This paper aims to bolster the Idea that the central idea of both Buddhism and existentialism is the consciousness of oneself as a real person.
Cold Atmospheric Plasma Metallization of Power Semiconductor Devices with CuSn Pseudo-Alloys for Diffusion Soldering
Authors: Ockel Manuela , Gökçen Aleyna , Ottinger Bettina , Petersen Matthias , Voigt Christian , Franke Jörg
Published: August 2024

Cold atmospheric plasma spraying is used to produce thin coatings of copper and tin between 20-80 μm thickness for use in diffusion soldering. This study presents an alternative process to apply composite solders directly onto power electronic bare dies. The formation of intermetallic phases may be promoted by the homogeneous distribution of the Cu and Sn particles as they are presented not in a layered structure but as a pseudo alloy within the coating. The Cu and Sn powder is mixed in situ using two powder conveyors, enabling adjustable mix ratios. The presented approach has been shown to produce a homogeneous particle distribution within the coating. Furthermore, preliminary experiments indicate the feasibility of the technology for applications in diffusion soldering.
Subsurface Weave Pattern Influences on Cold Spray Deposits onto Woven Fiber Reinforced Composites
Authors: Kaminskyj Madison , Mennie Nicholas , Singh Nand , Koohbor Behrad , Haas Francis M.
Published: August 2024

The polymer cold spray (CS) process has been demonstrated as a promising coating and repair technique for fiber-reinforced polymer composites (FRPs). However, a noticeable variation in coating thickness (herein referred to as checkerboard pattern) often occurs in the initial (bond) layer of low-pressure CS deposition. The checkerboard pattern occurs due to essentially periodic variations in matrix thickness above the subsurface fiber weave pattern. When the bond layer exhibits the so-called checkerboard pattern, the CS deposition for subsequent layers may be negatively affected in terms of deposition efficiency, porosity, adhesion, surface roughness, and surface thickness consistency. The present work compares results of both numerical simulations and experimental studies performed to reveal the governing mechanisms for and elimination of checker-boarding. Numerical single particle impact simulations are conducted to observe various thermomechanical domains for CS impact on the FRP surface in different regions of the composite material. Complementary experimental CS studies of exemplar powders onto FRPs with various surface interlayer thicknesses are also presented. Experimental analyzes of deposits include microstructural observations to compare against the simulations while also providing practical strategies for the elimination of checkerboarding effects.

Restoring the damaged shaft parts to extend their service life is an economical and environmentally friendly solution. In recent years, the laser metal deposition (LMD) process has received increasing attention in component restoration. However, the residual stress and deformation inevitably occur due to the heat input, leading to the deflection of the repaired shafts. Therefore, this study aims to minimize the deflection of LMD-repaired shaft parts through parameter optimization. The width and height of the LMD deposit as a function of the laser power and traverse speed were achieved by fitting a series of one-pass experimental results. Based on it, the finite element analysis was conducted to clarify the effect of the repairing conditions (e.g., laser power, traverse speed, and initial substrate temperature) on the deflection and residual stress distribution of the shaft parts after LMD repairing. A 304 stainless steel round bar with a diameter of 6 mm was served as the component to be repaired. The deposit was 316L stainless steel, whose deposition process was realized by the element birth and death technique. The results indicated that the free-end of the specimen experienced complicated deformation during the LMD and cooling process. After cooling off, the substrate presents a residual compressive stress along the axial direction. Moreover, the substrate deflection can be reduced by improving the initial substrate temperature. This study provided an important reference for optimizing the process parameters in repairing the shaft parts.

The method of simulating the wear performance under working conditions using a high-temperature ultra-high-speed wear testing machine was adopted to study the effect of feed rate variation on the wear behavior and scraping performance of the AlSi/hBN sealing coating and TC4 simulated blades. The macro and micro morphology of the coating and blades were analyzed by stereomicroscope and scanning electron microscope (SEM). The phase composition of the coating was analyzed by energy dispersive spectrometer (EDS) and X-ray diffraction. The results showed that, under the conditions of temperature of 450°C, line velocity of 300m/s, and feed depth of 500μm, the change in feed rate significantly affected the macro and micro morphology and wear mechanism of the AlSi/hBN sealing coating-TC4 simulated blades. At low feed rates, severe wear occurred, mainly manifested as grooving, adhesion transfer, and overheating mechanisms. At medium to high feed rates, good machinability was observed, mainly manifested as cutting and transfer of coating material to the blades.

The need for effective electrical insulation coupled with good thermal conductivity in power electronics has led to an exploration of suitable solutions for components like Insulated-Gate Bipolar Transistors (IGBTs). Considering its material properties, AlN emerges as a promising candidate for this application due to its high thermal conductivity, good electrical insulation and ample dielectric strength. However, aluminium nitride (AlN) has a low deposition efficiency when applied by atmospheric plasma spraying (APS). In contrast to AlN, alumina has a very good deposition efficiency during thermal spraying. Feedstock development was conducted to enhance the coating deposition for AlN. Therefore, a parameter study was carried out with AlN feedstock material to form a protective alumina shell around the AlN particles. Subsequently, the heat-treated powder was applied on an aluminium substrate by APS. X-ray diffraction (XRD) analysis displayed that, the heat-treated feedstock material contained AlN and α-Al2O3 phases. It was observed from scanning electron microscopy (SEM) analysis that the AlN particles formed an oxide shell which led to an enhanced deposition efficiency with a high amount of AlN in the coating. The coatings were also investigated by XRD and SEM to prove the presence of AlN and alumina. For the first time, oxide shelled AlN was successfully applied by thermal spraying with sufficient coating deposition and enhanced AlN-content in the coating.

Due to their promising photocatalytic properties under visible light irradiation, thermally sprayed ZnO-TiO2 coatings are of interest as substitute for TiO2 for various industrial applications, like hydrogen production via water splitting or the reduction of organic pollutants in water. Suspension spraying is an effective method to produce coatings in the binary ZnO-TiO2 system to form Zn2TiO4 in-situ during the spraying process. Aqueous suspensions containing fine dispersed ZnO and TiO2 particles are mixed at tailored composition and sprayed using the SHVOF and SPS spraying processes. Coatings with homogeneous distribution of elements and different surface structures and phase compositions are obtained. The phase composition is analyzed via XRD. UV-Vis spectroscopy measurements and photocatalytic tests of Rhodamin B degradation are performed. The potential to use appropriate binary suspension feedstock to produce ZnO-TiO2-Zn2TiO4 coatings with different microstructures and photocatalytic properties is presented.

This work focuses on the laser cladding process and the behavior or interaction between the powder particles and the laser beam, specifically examining how various process parameters might affect the creation of melt pool formations. The experiment focused on examining the influence of laser intensity and other important factors on the amount of metal in the substrate of 316L stainless steel, particularly while utilizing Inconel 625 powder. The study was conducted by utilizing cross-sectional images and quantifying the ratio of areas of the melted substrate material across a sliced cross-sectional area. The study also investigated the influence of recirculation patterns resulting from the Marangoni convection force on the formation of the melt region. The study's results indicate that a low powder feed rate is preferable, which in this study was 5 g/min, and provides better results with a symmetrical and profound melt profile. The melt shifts to asymmetrical profiles when the feed rate increases significantly over this value. The primary cause of this phenomenon is attributed to the Marangoni forces and the momentum transfer generated by the powder jets. The investigation also emphasizes the complex interplay among the process factors and highlights the crucial role of laser source power in triggering a fast escalation in the volume of melted material. In addition, the study supports the idea that maintaining the laser energy input as a constant helps to create a consistency in the total melt area even when the cladding speed is increased.
