Abstract

Peatlands are globally important ecosystems for carbon storage and climate regulation, yet hydrological drainage for agriculture and infrastructure has disrupted their ecological balance. This study examined the effects of drainage on soil microbial communities and microbial biomass carbon (MBC) in Badas Peatland, Brunei Darussalam. Soil samples were collected along two transects (Jalan Badas Middle and North) and analyzed using microBIOMETER® and plate count methods. Results revealed that fungal abundance and MBC increased with distance from the drainage canal, whereas bacterial and actinomycete counts decreased. The fungal-to-bacterial ratio showed a strong positive correlation with MBC, indicating that drainage adversely affects fungal populations and soil carbon retention. These findings highlight that fungi are more sensitive to drainage-induced stress than bacteria, reducing the peatland’s capacity for carbon sequestration. The study emphasizes the need for sustainable water management strategies to preserve soil microbiology and mitigate carbon loss from tropical peatlands.

Abstract

Overheating remains a major limitation to photovoltaic (PV) efficiency in high-temperature environments because excessive surface heat reduces electrical conversion and accelerates material degradation. This study integrates bibliometric and experimental approaches to develop a novel phase change composite (PCM) by combining paraffin with green composite materials (GCMs) derived from agricultural waste (pomegranate peel, sumac, and starch). Five PV panels with different PCM/GCM mixtures were tested under identical conditions to identify the most effective formulation. The optimal composition (57% paraffin and 43% pomegranate peel) achieved a melting point of 72°C and thermal conductivity of 0.1617 W/m.K, resulting in a 16.65% increase in daily energy output (240.98 Wh). Infrared imaging confirmed uniform temperature distribution and elimination of hot spots. The optimal condition was achieved because the fibrous pomegranate structure increased the melting point and stabilized the paraffin matrix, creating a porous network that improved heat absorption and distribution. This enhanced thermal regulation reduced surface temperature and hot spots, resulting in higher PV efficiency and energy output. This sustainable and low-cost innovation supports sustainable development goals (SDGs).

Abstract

This work integrates bibliometric analysis with laboratory experiments to develop nanotechnology-based water treatment technologies, aligning with Sustainable Development Goals (SDGs) on providing clean water and sanitation. A high-adsorption nanomaterial composed of reduced graphene oxide (rGO) doped with vanadium pentoxide (V₂O₅) was prepared using thermal doping and analyzed using XRD, FESEM, and FTIR techniques. This composite demonstrated the ability to remove 68.98% of methyl orange dye in just 30 minutes. Kinetic and adsorption studies showed conformed to a quasi-second-order kinetic model and a Langmuir single-layer adsorption model, indicating strong chemisorption and surface homogeneity. This high performance is attributed to the synergistic effect between V₂O₅ and rGO in contributing high surface area, improving electron transport, and enhancing effective sites for capturing dye molecules. This nanocomposite is a sustainable and economical option for supporting the smart architecture of urban water systems, contributing to SDGs.

Abstract

This study investigates the mechanical and tribological behavior of polyvinylidene fluoride (PVDF)/unsaturated polyester resin (UPR) composites reinforced with 1–5% multi-walled carbon nanotubes (MWCNTs). Research on PVDF-based nanocomposites has increased significantly, according to a quick bibliometric screening of Scopus-indexed publications. MWCNTs were found to be one of the most influential reinforcement keywords, indicating a high level of interest in mechanically optimized polymer systems worldwide. In this study, specimens were tested for tensile, flexural, hardness, impact, wear, and reversed-bending fatigue performance. Results reveal that 3% MWCNT provides optimal strengthening, improving tensile and flexural properties, hardness, wear resistance, and fatigue life while reducing void content. Finite element simulations using ANSYS aligned with experimental findings, showing deviations below 10%. Statistical analysis (ANOVA) confirmed significant effects of MWCNT content. Overall, PVDF/UPR–MWCNT composites demonstrate excellent potential for advanced lightweight structural applications.

Abstract

Proper wound cleansing is a fundamental step in preventing infection and supporting effective wound management. This study aimed to develop and evaluate a film-forming antiseptic spray composed of chitosan, polyvinyl alcohol, and polyhexamethylene biguanide for wound cleansing applications. The formulation was prepared using a solution-based approach and characterized in terms of morphology, chemical interactions, sprayability, film formation stability, antibacterial, and antibiofilm performance. The developed spray demonstrated uniform application, stable film formation, and effective incorporation of the antimicrobial agent. Biological evaluations confirmed enhanced antibacterial and antibiofilm activity because of synergistic interactions between the biopolymer matrix and the cationic antiseptic component. This study was further supported by bibliometric evidence indicating a growing global research focus on wound care materials and film-forming antiseptic sprays, emphasizing their relevance to sustainable healthcare innovation. The findings contribute to the advancement of sustainable wound care technologies and align with the Sustainable Development Goals, particularly the goal of promoting good health and well-being.

Abstract

This study investigates the influence of axial displacement and shaft sagging on the performance of permanent magnetic bearings (PMBs) in horizontal overhung systems, supported by a bibliometric analysis of existing PMB research trends. The bibliometric review identifies dominant modelling approaches and reveals limited attention to axial displacement and shaft sagging effects in stacked PMB configurations. To address this gap, a modified analytical model based on Backers’s magnetic scalar potential method is developed by incorporating axial displacement and shaft sagging into the design framework. The proposed model is validated through experimental investigation using a horizontal overhung rotor system. The results show that the combined effects of axial displacement and shaft sagging significantly alter magnetic alignment and reduce effective wavelength, leading to performance degradation. Statistical equivalence testing confirms strong agreement between the proposed formulation and established analytical models. The findings provide improved design guidance for enhancing PMB stability, reliability, and efficiency in practical rotating machinery applications.

Abstract

Fourier Transform Infrared (FTIR) spectroscopy is widely used for materials characterization; however, spectrum interpretation often relies on isolated peak identification, which can lead to ambiguity, especially for complex materials. This study presents a master FTIR dataset combined with a step-by-step guided peak-correlation workflow to support systematic and reproducible FTIR interpretation. The dataset organizes FTIR information into five spectral regions and emphasizes correlated peak families rather than individual bands. Representative examples covering simple compounds, organic compounds, polymers, and halogenated materials demonstrate the applicability of the approach across materials science and chemical engineering fields. Beyond manual interpretation, the structured dataset and workflow are designed to be machine-readable and extensible, enabling future integration with data-driven methods such as artificial intelligence (AI) and machine learning (ML) for automated spectral analysis. This work provides a practical reference for FTIR interpretation, education, and the development of intelligent materials characterization systems.
