The boundary layer flow of immiscible fluids plays a crucial role across various industries, influencing advancements in industrial processes, environmental systems, healthcare and more. This study explores the thermally radiative boundary layer flow of a shear-driven Ree–Eyring fluid over a nanofluid. The investigation offers valuable insights into the intricate dynamics and heat transfer behavior that arise when a nanofluid, affected by thermal radiation, interacts with a non-Newtonian Ree–Eyring fluid. This analysis contributes to a deeper understanding of the complex interactions governing such systems, which is essential for enhancing efficiency and innovation in multiple applications.

The simulation investigates the convergence of boundary layers under varying shear strengths. A comparative analysis is conducted using γAl2O3 and Al₂O₃ nanoparticles, with water as the base fluid. The model’s numerical outcomes are derived using the bvp4c method through the application of appropriate similarity transformations. The resulting numerical data are then used to produce graphical representations, offering valuable insights into the influence of key parameters on flow behavior and patterns.

The temperature of the Al₂O₃ nanoparticles is always higher than the γAl2O3 nanoparticles, and hence, Al₂O₃ nanoparticles become more significant in the cooling process then γAl2O3 nanoparticles. It is also observed that the fluid velocity for both regions is enhanced by increasing values of the Ree–Eyring fluid parameter.

The results stated are original and new with the thermal radiative boundary layer flow of two immiscible Ree–Eyring fluid and Al₂O₃/γAl2O3 nanofluid.

The coating process increases the durability, quality and effectiveness of the web, is used in manufacturing of wallpapers, adhesive tapes, wrapping, protection of fabrics and metals, X-ray and photographic films, beautification, books and magazines, film foils, magnetic records, coated paper, etc.

This paper gives a detailed study of the Oldroyd-4 constant fluid rheology during blade coating technique to check the sensitivity of velocity slippage on blade surface and magnetohydrodynamics (MHD) on final coating thickness and other mechanical properties. Heat transfer effects are also considered with viscous dissipation. The governing expressions under Lubrication Approximation Theory (LAT) are shortened and non-dimensionalized. A numerical technique with root finding algorithm is employed to determine the velocity profile, pressure and pressure gradient, shear stress, coating thickness, blade load and temperature profile. Figures and tables are exploited to show and discuss the effects of Hartmann number, slip parameter, geometrical parameter and viscoelastic fluid parameters on the flow and mechanical quantities. Comparison is also presented with previous literature under specific conditions.

From a technical vantage point, blade load and pressure are significant results of research as they lead to varying coating thickness, which gives an efficient coating process and extends substrate life. Shear stress is directly proportional to the magnetic parameter and inversely proportional to velocity slippage on blade surface. Temperature curve increases with increment in magnetic parameter and Brinkman number, while decrease in temperature is detected from slip parameter.

In literature, this investigation fills a gap in the numerical prediction of slip and MHD effects on the thin layer coating of rheological viscoelastic fluid during blade coating phenomena.

Hybrid nanofluids have remarkable characteristics for improving the process of heat transfer. The findings suggest hybrid nanofluids are beneficial heat transfer fluids for industrial uses. Therefore, this article aims to investigate the Darcy–Forchheimer flow of Zn-TiO_2/H2O hybrid nanofluids through a vertically porous shrinking cylinder.

The thermal transportation phenomenon of radiated hybrid nanomaterials is studied subject to linear thermal radiation and chemical species with the consequence of non-uniform heat source/sink influence. The controlling flow and energy equations in the form of governing hybrid nanofluids are developed and then converted into ODEs by operating appropriate resemblance variables. Using the impacts of controlling parameters, the behaviors of flow constraints are interpreted graphically.

The current study’s outcomes reveal that the water-based hybrid nanomaterials show a promising upsurge in heat transfer rate. Similarly, as the mass transfer rate grows, the drag coefficient and energy transfer rate boost, while due to curvature relations, it tends to diminish for drag friction. In an upper branch solution, the flow field is improved by greater porosity parameter values, whereas in a lower branch solution, it deteriorates. Furthermore, the velocity profile depicts the opposite trend for upper and lower branches due to a boost in the mixed convection parameter.

In light of already conducted studies, the relation of internal heat source varying regarding thermal and space in the rheology of hybrid TiO₂-Zn/H_2O nanofluid possesses intriguing utilization in energy production strategies due to the exhibition of extensive heat energy. The most typical examples of this phenomenon can be observed in nuclear and chemical-reactor power stations, solar power plants for heating and cooling systems, combustion analysis equipment and so on. The current study is devoted to predicting the effect of a varied heat source on the thermal energy characteristics of mixed convective hybrid TiO_2-Zn/H2O nanofluid flow through the vertical cylinder.

Based on the principles of the social capital theory (SCT), this study aimed to generate hypotheses and evaluate a mediated moderated model that examined the impact of social capital on online brand community happiness (OBCH).

Using 215 online questionnaires from users of private online brand communities (OBCs) , researchers examined the hypothesized connections between variables. The SPSS 21.0 and AMOS 26.0 were applied to fulfill the purpose.

For the goodness of model fit, the authors have applied cut off criteria for fit indexes given by Hu and Bentler (1999) and model-fit measures indicators, i.e. CMIN/DF 1.397, CFI 0.958, SRMR 0.045, RMSEA 0.043 and PCLOSE 0.866, which meet the minimum acceptable criteria. Based on the results, social capital significantly affects psychological well-being (PWB), which, consequently, leads toward increased happiness among OBCs. Furthermore, membership duration moderates the relationship between PWB and OBCs.

The authors have utilized a cross-sectional research design, and it limits the researcher’s ability to generalize the findings. These findings imply how social capital leverages PWB and OBCH. Moreover, the presence of membership duration helps to understand that members who spend more time in the community are happier in the OBCs.

In this age of social media, it provides valuable guidance to the administrators of private Facebook groups dedicated to specific brands, enhancing the definition and development of OBC operations and community interactions.

This research takes a broader look at social capital’s impact on happiness among private OBCs. The current research contributes to the existing body of work by emphasizing the role of PWB in generating happiness. The study is novel in examining the mediating moderating model of PWB and membership duration to explore deep insights for social media platforms.

This paper aims to examine the mediating role of employees’ intrinsic motivation in the relationship between perceived ambidextrous organizational culture and innovative behaviour among information technology (IT) sector employees.

The study used a quantitative research methodology, using a questionnaire to gather data from a sample of 510 employees across a range of IT organizations and various roles in the Indian IT sector. Smart partial least squares structural equation modeling Version 3 was used for the analysis and interpretation of the study.

The findings revealed a significant positive relationship between perceived ambidextrous organizational culture and employees’ innovative behaviour in the Indian IT sector. Moreover, the study established that employees’ intrinsic motivation played a significant mediating role in this relationship.

This study stands out for its exploration into how employees’ intrinsic motivation mediates the relationship between ambidextrous organizational culture and innovative behaviour. It offers valuable insights for enhancing organizational creativity by understanding the critical role of intrinsic motivation.

This study aims to evaluate the activation of personality traits (PTs) as a means of explaining the emergence of intrapreneurial behaviour (IB) in engineers, particularly in response to goal-setting freedom (GSF) cues. Hence, this study proposes and empirically assesses the theoretical model underpinning trait activation theory (TAT), enriching its application by integrating goal-setting theory.

The proposed theoretical model was evaluated through a cross-sectional survey of 296 engineers in Pakistan’s textile industry. Testing of hypotheses using analysis of the data was done using partial least squares structural equation modelling (PLS-SEM).

The obtained results revealed a positive relationship between the PTs of extraversion, conscientiousness, openness to experience and emotional stability with IB, while agreeableness was not found to have a significant relationship. The situational cue of GSF activated these traits, validating the theoretical model and demonstrating the contextual influence of autonomy on personality expression.

Granting engineers greater GSF can significantly enhance their IB. Organisations should foster environments that support autonomy to drive innovation, leveraging the intrinsic motivation and creativity of their engineers. This approach can lead to increased innovation, proactive problem-solving and competitive advantage.

This study contributes to the literature by extending TAT within the textile industry, illustrating how GSF acts as a situational moderator. It bridges gaps in understanding sector-specific dynamics and underscores the role of autonomy in activating PTs to foster innovation, proactiveness and risk-taking behaviours in organisational contexts.

This study, drawing on the attribution, attachment, and regret theories, examined the predictors of brand love. It also aimed to assess the mediating role of brand authenticity dimensions, i.e. brand continuity, brand credibility and brand naturalness, on the relationship between customer perception of hotel corporate social responsibility (CSR) initiatives and brand love. The moderating role of alternative attractiveness was also evaluated in relation to customer perception of hotel CSR initiatives and brand authenticity dimensions.

The authors surveyed customers from hotels in different cities in Pakistan. To test the theoretical framework, partial least square-based structural equation modeling was used.

The results confirm customer perception of hotel CSR initiatives as a predictor of brand love. The partial mediating role of brand naturalness and brand credibility was found between customer perception of hotel CSR initiatives and brand love, and no mediation of brand continuity was found. Alternative attractiveness negatively moderated the link between customer perception of hotel CSR initiatives, brand credibility and brand naturalness. However, alternative attractiveness did not moderate the relationship between customer perception of hotel CSR initiatives and brand continuity.

Hospitality practitioners can enhance brand love by strategically communicating CSR initiatives to customers, prioritizing brand credibility and brand naturalness and considering the role of attractive alternatives. This knowledge empowers practitioners to make informed decisions that can significantly impact their brand’s success.

This is the first study to explore the moderating role of alternative attractiveness on the relationship between customer perception of hotel CSR initiatives and brand authenticity dimensions. Equally, it is the first to investigate the mediating role of brand authenticity dimensions on the relationship between customer perception of hotel CSR initiatives and brand love.
