Abstract

Vegetable oil-based cutting fluids have emerged as a promising innovation in machining operations, supporting the advancement of sustainable and eco-friendly manufacturing practices. This study delves into the development of a biolubricant derived from corn oil, enriched with 0.15% mass fractions of various nanoparticles, including calcium carbonate (CaCO3), copper oxide (CuO), and multi-walled carbon nanotubes (MWCNT). These nano-cutting fluids were applied through the Minimum Quantity Lubrication (MQL) method during CNC milling of AISI 1045 steel. The investigation focused on evaluating thermophysical properties, including density, thermal conductivity, and dynamic viscosity, as well as tool wear performance. The results demonstrated that CuO nanoparticles yielded the highest density, while MWCNT exhibited superior thermal conductivity and viscosity. Among all samples, the fluid with MWCNT showed the most effective performance in minimizing tool wear. This study highlights the potential of nanoparticle-enriched vegetable-based cutting fluids as high-performance, environmentally responsible alternatives to conventional mineral oil-based lubricants, promoting greener machining in the manufacturing industry.

Abstract

This study investigates the performance of soybean oil-based nano-lubricants with CuO, graphene, and CuO/graphene hybrids under MQL-assisted CNC milling of AISI 1045 steel. The research aims to evaluate the thermophysical, rheological, and tribological properties of various lubricant formulations, including pure soybean oil and soybean oil with individual or hybrid nanoparticle additives. Nanoparticles were characterized by SEM, XRD, and FTIR, and fluid samples were evaluated for density, viscosity, thermal conductivity, sedimentation stability, and rheological behavior. Machining performance was assessed through tool wear, surface roughness, cutting temperature, wear debris morphology, and chip color analysis. Results showed that adding graphene nanoparticles significantly improved machining performance, achieving a surface roughness of 1.033 µm, tool wear of 0.0493 mm, and a cutting temperature of 46.1 °C, outperforming both conventional and alternative nanofluid formulations. Among all formulations, the graphene-based nanofluid delivered the lowest cutting temperature, surface roughness, and flank wear under MQL. The CuO/graphene hybrid improved performance relative to the base fluids but did not surpass the graphene formulation, indicating limited synergistic benefits under the present soybean oil-based-MQL conditions.

Abstract

The well-being of faculty and staff in higher education has increasingly become a global concern, particularly during the COVID-19 pandemic. However, existing research remains fragmented and lacks a unified theoretical framework. This study aimed to synthesize empirical evidence on faculty and staff mental health and to develop an integrative Academic Well-Being model for higher-education settings. A Systematic Integrative Review (SLR) was conducted in accordance with PRISMA 2020. Seventeen peer-reviewed international studies published between 2017 and 2025 were analyzed through thematic synthesis. The findings reveal that academic well-being is a multidimensional construct encompassing eight key dimensions: psychological, social, organizational, spiritual, physical, digital, financial, and cultural policy. Psychological well-being and empathetic leadership emerged as central determinants, while digital adaptation, spiritual meaning, and financial security are emerging factors in the post-pandemic period. The synthesis resulted in an Ecological Model of Academic Well-Being (EAWB) comprising four nested levels: individual, interpersonal, organizational, and cultural systemic that interact dynamically to shape mental health and professional flourishing in academia. The model highlights that sustainable well-being arises not from personal resilience but from compassionate leadership, organizational justice, and inclusive cultures. This review contributes a holistic framework for transforming universities into compassionate ecosystems. Keywords: academic well-being model, mental health, university staff, higher education

Abstract

This study has reported the effects of different formulation ratio between recycled high density polyethylene (r-HDPE) and recycled polypropylene (r-PP) into the resulted mechanical, thermal and morphological properties of r-HDPE/r-PP polymeric blends. About five (5) different formulation ratio of r-HDPE/r-PP have been prepared and tested. The best combination ratio between r-HDPE and r-PP was determined in this work. It was found that the 70/30 wt.% of r-HDPE/r-PP blend possessed an outstanding mechanical and physical strength. About 59.80% and 2.30% of positive improvement in comparison to 0/100 wt.% of r-HDPE/r-PP was achieved for both of tensile strength and hardness, respectively. Interestingly, for 70/30 wt.% of r-HDPE/r-PP blend had also experienced major increased in their elongation at break up to 473%. The fracture morphological behavior of the tested samples that were observed via SEM observation, had established the interaction between the structure and properties of produced r-HDPE/r-PP blends, especially on the miscibility state between the r-HDPE and r-PP phases. Thermal evaluation by using the DSC had confirmed the partial miscibility state due to dominant peak shifting at 120 - 140°C and obvious melting peak reduction pattern. Overall, from this study, it was found that the blending between r-HDPE and r-PP into r-HDPE/r-PP blends are feasible to improve the properties of primary phase.

Abstract

This research was conducted to investigate the effect of binder variation including bentonit, lapindo mud, and portland cement on the silica molding sand strength, permeability, fluidity, metal hardness and the quality of Al-Si alloy casting by using gravity casting method. The experimental design was used on this research and analyzed by using descriptive data analysis. The result showed molding sand containing 15% lapindo mud binder had the highest wet compressive strength (8,73 N/cm2). The molding sand containing 15% portland cement binder had the highest dry compressive strength (>32 N/cm2). The highest wet tensile strength was resulted by the molding sand containing 15% bentonit binder (3,33 N/cm2), while the highest dry tensile strength was resulted by the molding sand containing 15% portland cement binder (18,60 N/cm2). The highest wet shear strength was resulted by the molding sand containing 15% portland cement binder (0,57 N/cm2), while the highest dry shear strength was resulted by the molding sand containing 15% portland cement binder (1,03 N/cm2). The molding sand containing 15% bentonit binder had the finest permeability (210 mm/minute). In the real practical application, the molding sand containing 15% portland cement binder was unable to result an appropriate molding strength when manually compressed in cope and drag (casting flask), thus it was unable to use as metal pouring media. The molding sand containing 15% lapindo mud binder had the finest fluidity but it had the lowest hardness (120,30 HV). The molding sand containing 15% bentonit binder resulted the best Al-Si alloy casting quality and the highest hardness (129,60 HV).
