Abstract

Wirebonding is a fundamental process in semiconductor manufacturing, essential for creating reliable electrical connections between integrated circuits and their packaging. This paper explores the complexities of interface stresses arising from solid-state diffusion during wirebonding, with particular attention to the interactions between gold (Au) wires and aluminum (Al) bond pads. Due to the different diffusion rates of Au and Al atoms, intermetallic compounds (IMCs) form at the interface, playing a critical role in bond integrity. However, the growth of these IMCs also generates significant mechanical stresses, which can compromise the reliability and lifespan of wirebonded connections. Through detailed experimental analysis, this study investigates the kinetics of IMC growth, the influence of activation energy on diffusion, and the resulting microstructural evolution at bonded interfaces. By clarifying the mechanisms driving IMC formation and associated stresses, the paper offers insights into optimizing wirebonding processes. These include the selection of suitable bonding parameters and materials to reduce stress and enhance the performance and durability of semiconductor devices. Ultimately, the findings support the advancement of wirebonding techniques aimed at improving the reliability and efficiency of semiconductor packaging.

Abstract

This study investigated how the width–diameter ratio of twisted tape inserts and tube size influence heat transfer and pressure loss in circular heat exchanger tubes under turbulent air flow. A three-dimensional steady CFD model with an SST k–omega turbulence closure simulated uniformly heated tubes containing constant pitch tapes across multiple diameters and ratios. Grid independence and literature validation established numerical reliability. A mid-size tube consistently delivered the best thermal performance, and the largest tested width–diameter ratio produced the highest Nusselt enhancement while keeping pressure penalties manageable. The inserts markedly outperformed a plain tube in overall heat transfer. Performance improves because swirl from the tape strengthens core to wall mixing and thins the thermal boundary layer without excessively raising friction at suitable geometries. Findings guide compact, energy-efficient exchanger design by identifying geometry combinations that maximize heat transfer for practical pumping power. Designers can apply the framework across diverse operating conditions.

Abstract

This study investigates the thermal effects on the mechanical performance of adhesively bonded T-joints, with a focus on optimizing bond strength under elevated temperatures. Using tensile testing, four adhesive thicknesses (0.5, 1.0, 1.5, and 2.0 mm) were examined across five temperatures (room temperature to 100°C). Results reveal that tensile strength peaked at 35°C, aligning with the adhesive's glass transition temperature (Tg), with 1.5 mm thickness yielding optimal performance. Thicker bonds (2.0 mm) exhibited superior strength at higher temperatures (55–100°C), while thinner bonds performed best at lower temperatures. Differential Scanning Calorimetry and SEM analyses confirmed thermal degradation and morphological changes as key factors influencing strength. These findings highlight the relationship between adhesive thickness, thermal exposure, and structural integrity, providing critical insights for the aerospace and automotive industries. The study aligns with SDG 9 (Industry, Innovation, and Infrastructure) by supporting durable design practices and contributes to the bibliometric discourse on epoxy-based adhesive technologies under thermal stress.

Abstract

We evaluate liquid desiccant–assisted coalescence to dehydrate bio-based oligomers and break water in oil emulsions under mild conditions. An experimental packed column contacted epoxidized oil with glycol in counter-current at moderate temperature and ambient pressure; moisture was measured by Karl Fischer; a thermodynamic model using cubic plus association assessed desiccant flow effects. The column operated under an apparent laminar regime to maintain film stability and encourage coalescence without disruptive turbulence. The system achieved specification moisture, and model trends agreed with experiments; laminar hydraulics promoted droplet growth and rapid gravitational separation; compared with vacuum drying, the approach delivered shorter drying duration and lower energy demand. Dehydration accelerated because glycol absorbs water, stabilizes film drainage, enlarges droplets on packing, and minimizes back mixing when flow is controlled. The approach enables continuous, economical dehydration of palm-based oligomers with simple operation, compatibility with downstream processes, and scalability for industrial production and reliability.

Abstract

This study aims to evaluate the combined effect of water-in-biodiesel emulsions (WBE) and oxy-hydrogen (HHO) enrichment on diesel engine performance and emissions. Experiments were conducted on a single-cylinder diesel engine fueled with B35 (35% biodiesel–65% diesel), WBE5 (5% water-in-biodiesel emulsion), and their HHO-enriched blends under 1–4 kW loads. Engine performance was assessed through brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust gas temperature (EGT), while emissions of NOx, CO, and CO₂ were measured. Results show that WBE5 reduced NOx emissions by up to 30.2% compared with B35 and improved BSFC by 6.2% and BTE by 8.4% at 2–3 kW loads. However, CO emissions increased by about 18% due to lower combustion temperatures. HHO enrichment improved BSFC and BTE at light loads (1–2 kW) by up to 2% and decreased CO emissions through enhanced oxidation, but its influence on NOx was minimal and diminished at higher loads. Overall, WBE–HHO dual-fuel operation provides partial advantages, particularly under light-to-medium loads, offering a feasible pathway toward cleaner and more efficient diesel engine operation without major modifications.

Abstract

This study reports the sustainable synthesis, characterization, and application of Interpenetrating Polymer Networks (IPNs) derived from post-consumer polystyrene kitchenware and epoxy resin residues as a cost-effective adsorbent for amoxicillin removal from wastewater. The conversion of these polymeric wastes into functional materials aligns with circular economy strategies. Batch adsorption experiments were carried out to examine the effects of key operational parameters, including adsorbent dosage, contact time, and solution pH. The results showed a maximum removal efficiency (96%) at an adsorbent dosage of 0.1 g and pH 5. Kinetic analysis indicated that the adsorption process followed a pseudo-second-order model, suggesting chemisorption as the dominant mechanism, with an equilibrium adsorption capacity (qe) of 8.13 mg/g. Isotherm modeling demonstrated that the Langmuir model provided the best fit, confirming monolayer adsorption on a homogeneous surface, while Temkin parameters indicated favorable adsorption energetics. Overall, these findings highlight the potential of waste-derived IPNs as eco-friendly and highly effective materials for removing pharmaceutical contaminants from aqueous environments, contributing to the advancement of sustainable wastewater treatment technologies.

Abstract

This study presents a comprehensive analysis of the physical, mechanical, wettability, shear, and bonding performance properties of rubberwood within and between trunks of various diameters bonded with different adhesives for sustainable engineered timber construction. Rubberwood samples from trunks of different sizes were tested for density, modulus of rupture, modulus of elasticity, compressive strength, shear strength, and wettability. Polyvinyl acetate (PVAc) and polyurethane (PUR) adhesives were applied under varying clamping pressures to evaluate bonding strength and wood failure behavior. The results revealed minimal variation in physical and mechanical properties across radial positions and trunk diameters, while PVAc achieved slightly higher bonding efficiency. Wettability remained stable across zones and surfaces. A bibliometric analysis highlighted increasing global interest in rubberwood and bio-based materials for sustainable construction, emphasizing its relevance to the Sustainable Development Goals (SDGs) and its potential as a renewable material for green innovation.

Abstract

This study examines the influence of relative humidity (RH) on the electrochemical and structural properties of polyvinyl alcohol (PVA) composite films reinforced with MXene, zinc oxide (ZnO), and cellulose nanocrystals (CNC). Composite films were fabricated via solvent casting and conditioned at RH levels of 50%, 75%, and 94%. Cyclic voltammetry and four-point probe tests revealed substantial enhancements in current density, specific capacitance, and bulk conductivity with increasing RH, attributed to improved ionic mobility and interfacial polarization. X-ray diffraction indicated reduced crystallinity due to polymer swelling, while scanning electron microscopy showed enhanced MXene dispersion at higher RH. Fourier-transform infrared spectroscopy confirmed intensified hydroxyl interactions, reflecting increased hydrophilicity. These humidity-induced improvements suggest promising applications in humidity-responsive flexible electronics and sensors. However, potential trade-offs include reduced mechanical stability under prolonged exposure. The findings offer new insights for optimizing hydrophilic polymer composites to enhance environmental adaptability and advanced device performance.

Abstract

Vortex-induced vibration (VIV) poses a critical threat to the integrity and fatigue life of marine and offshore structures. This study evaluates the effectiveness of a truncated cone fouling suppression device in reducing VIV of a low-mass ratio circular cylinder. Experiments were performed in a circulating water flume at Reynolds numbers ranging from 8,000 to 45,000, using various surface coverage ratios. The vibration amplitude and frequency responses were analyzed to determine suppression performance. Results showed that the device reduced oscillation amplitude by up to 68% within the lock-in region, with optimal suppression observed at 25-50% coverage. This indicates that partial surface modification enhances flow–structure interaction and weakens wake coherence. Furthermore, a bibliometric analysis was integrated to identify research trends and gaps in passive vibration control. The present approach provides both scientific and practical insights for developing low-drag, efficient, and sustainable VIV mitigation strategies in marine engineering.
