The increasing demand for portable and sustainable power sources has accelerated research into triboelectric nanogenerators (TENGs), which convert mechanical energy from the environment into electrical energy. However, the widespread use of non-degradable materials in conventional TENGs raises serious environmental concerns. This review highlights the potential of biodegradable poly(butylene adipate-co-terephthalate) (PBAT) as a triboelectric material for the development of eco-friendly TENGs. Various fabrication techniques, including solvent casting and electrospinning, are discussed for the preparation of PBAT-based TENGs. According to current literature, the incorporation of nanomaterials into the PBAT matrix significantly enhances output performance, mechanical properties, and environmental compatibility. Additionally, this review explores the applications of PBAT-based TENGs in energy harvesting, self-powered sensors, biodegradable electronics, and environmental monitoring, emphasizing PBAT's contribution to sustainable TENG technology. The primary focus of this review is to explore solvent-free methods such as compression molding and 3D printing for fabricating PBAT films, which are then utilized in TENG device development.

Growing concerns over chemical toxicity and environmental impact have driven the development of sustainable mosquito-repellent textiles using biodegradable natural materials and nanotechnology. This review analyzes recent advancements in sustainable textile innovations, focusing on renewable raw materials, advanced encapsulation methods, key challenges, and future opportunities. Key findings suggest that biopolymers such as chitosan, cellulose, and alginate have highlighted significant performance as carriers for natural repellents like citronella, neem, and eucalyptus oils. Encapsulation techniques, including liposomes, polymeric nanoparticles, spray drying, and electrospinning, significantly enhance the stability, wash durability, and controlled release of active agents. Surface-level applications with zinc oxide, silver, and titanium dioxide nanoparticles provide multifunctional benefits, such as mosquito repellency, antimicrobial activity, and UV protection, without declining fabric breathability or comfort. The application of biodegradable materials encourages circular economy principles by enabling recyclability or biodegradability, thereby minimizing environmental challenges. Despite promising laboratory-scale results, challenges remain in scaling up production, ensuring regulatory compliance, and addressing the long-term ecological risks of nanomaterials. Future research should focus on green synthesis methods, optimizing bio-nano systems for improved performance, and ensuring safe, cost-effective functionalization into commercial textile manufacturing.

The continued release of synthetic dyes by the textile and allied industries is of great ecological and public-health relevance, because, in most cases, the traditional infrastructures of waste water treatment do not curb the complex chromophoric molecules. NiO NPs have also been found to be one of the most effective remediation agents due to their large surface area, chemical stability, and strong photocatalytic capabilities. This is a critical review of the current advances in chemical, green, and hybrid synthesis protocols, which expound how particle size, morphology, and surface-functionalisation dictate the efficacy of adsorption and the photocatalytic degradation pathways. The special focus is given to doped NiO systems and NiO based composites, which are characterized by an increased charge separation, modulation of the band-gap, and the production of reactive oxygen species. Comparative studies have shown how optimised NiO nanostructures can have removal efficiencies of more than 90–99 % of primary classes of dyes with visible or solar light. The review also outlines the current issues such as nanoparticle aggregation, low recoverability, and possible ecotoxicological effects, and suggests future research directions that could be useful to allow scalable, cost-effective, and sustainable application of NiO-based materials in industrial wastewater purification. Comprehensively, this synthesis provides a comprehensive mechanism structure that guides rational development of next generation NiO nanomaterials to be effectively used in the removal of dyes.

Proper power system operation in areas that have a high degree of climatic variability including Bangladesh requires proper solar power forecasting. This paper analyzes a cascade hybrid KNN–SVM model to predict solar power per hour and their performance is compared to standalone K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and Long Short-Term Memory (LSTM) models. Under the proposed method, the KNN algorithm is first used to determine the local data neighborhoods, and the second step is the localized regression on an SVM with a radial basis function (RBF) kernel. Root Mean Square Error (RMSE) is used to evaluate model performance on a series of forecasting targets. Hourly Total Global Solar Radiation (HTGSR) and Hourly Total Power Generation (HTPEG) are the least RMSE values of 0.0059 and 0.0058 respectively, which are the lowest for the hybrid KNN–SVM model. Although LSTM works well in situations where there are long temporal dependencies to be learned, the hybrid approach offers a more balanced trade off between instance-based learning and margin optimization, and thus is especially useful in situations where there are high short-term variations. These findings justify the feasibility of scaled-up solar energy integration into the power grid in Bangladesh and it will also help in the sustainable energy planning.

There is an increasing demand for environment-friendly methods of textile coloration. On this basis, there is rising emphasis on biodegradable natural dyes. Natural dyes are perceived to provide functionality beyond mere appearance. This research investigates the multifaceted sustainable dyeing of nylon using the aqueous extract of Babool bark (Acacia nilotica). It has focused its attention on chromatic parameters, fabric properties, the UV protection factor, and antibacterial activity. The variables associated with the process of dyeing included time, temperature, pH, and Material: Liquor (M: L) ratio, which have been systematically optimized. Optimum conditions identified at 100 °C, pH 4.8, 60 min, and an M:L ratio of 1:30. In such conditions, nylon fabric showed improved coloration with greater K/S values, CIELAB color coordinates, and good shade repeatability. SEM studies revealed even deposition of tannins and natural colorants, while increased temperature resulted in increased fabric surface roughness and degradation due to thermal effects. The FTIR revealed good hydrogen bonding interactions between the dye and nylon polymer chains. The colored textile demonstrated good UV protection factor, which improved from 12.1 to 87.62 UPF values, meeting specific demands for high UV protective application in functional textile products for protective and healthcare apparel due to its phenolic compounds found in Babool bark. Even in the absence of diffusion inhibition zones, surface bacterial resistances were demonstrated in Bacillus spp. and P. pseudomonas. The dyed fabric has good color fastness properties to washing, perspiration, and rubbing tests, though light fastness was moderate, which in turn could be improved through effective mordanting process. Mechanical strength and air-permeability values also stayed within acceptable ranges. The result clearly indicates that Babool bark extract is considered to be an efficient and sustainable natural dye that is preferable for achieving appropriate textile coloration, effective UV protection, and good color fastness properties of dyed nylon fabric.

This study evaluates the corrosion inhibition performance of selected carbonyl-based compounds; oxalic acid, sorbitol, EDTA, sodium glycolate, and sodium salicylate on magnesium exposed to 0.5 % NaCl solution using hydrogen evolution measurements over the temperature range 303–333 K. The inhibitors exhibited varying degrees of protection, with sorbitol and sodium salicylate demonstrating the highest inhibition efficiencies studied across the temperatures. Thermodynamic parameters such as entropy and enthalpy indicate endothermic and spontaneous adsorption behavior. Calculated Gibbs free energy values confirm the feasibility of inhibitor–surface interactions. Density functional theory (DFT) analysis provided insight into molecular reactivity, revealing that inhibitors with higher HOMO energies, lower HOMO–LUMO energy gaps, greater softness, and more favorable chemical potentials exhibited superior inhibition efficiency. The correlation between experimental data and quantum descriptors establishes electron-donating capability and molecular reactivity as key factors governing adsorption strength. Overall, the combined experimental and theoretical results highlight sorbitol and sodium salicylate as promising corrosion inhibitors for magnesium, contributing valuable understanding toward the development of Mg-based systems for energy and structural applications. However, sorbitol emerged with the highest inhibition efficiency (IE) and Utilization Efficiency (UE) suggesting that there may exist a relation between utilization efficiency and inhibition efficiency depending on molecular structure and electronic properties of the compound.

Growing environmental concerns associated with petroleum-based synthetic dyes have intensified the demand of sustainable natural colorants for textile applications. This research evaluates jackfruit (Artocarpus heterophyllus) wood shavings, an underutilized agricultural byproduct, as a renewable dye source for polyester dyeing, including its dual significance in waste valorization and environmentally sustainable processing. The colorant was extracted through alkaline extraction at 100 °C for 60 min, and polyester fabrics were subsequently dyed under systematically varied dyeing process parameters, including time (20–120 min), temperature (80–160 °C), and pH (4, 7, 9). FTIR spectroscopy revealed the presence of characteristic polyester bands alongside additional absorption features, indicative of interactions between dye constituents and the fiber surface. Dyeing induced measurable modifications in fabric performance, including reduced air permeability attributable to surface deposition and limited moisture transfer as evidenced by near-zero bottom-surface wetting and a negative one-way transport index. Chromatic assessment demonstrated that dyeing parameters significantly influenced chromatic parameters, with maximum color strength reaching (K/S) 10.39. Samples dyed at 140 °C for 100 min exhibited enhanced flame retardancy (29.1 s) and excellent wash, rubbing, light, and perspiration fastness (ratings 4–5). Acidic pH improved wash fastness, whereas neutral pH yielded superior rubbing, light, and perspiration resistance. The findings establish jackfruit wood shavings as a promising sustainable colorant capable of imparting functional and aesthetic value to polyester textiles.

This study evaluated the rheological characteristics of a hybrid asphalt binder integrating sawdust, garnet waste, and palm oil fuel ash (POFA). Approximately 0 %, 3 %, 6 %, and 9 % of hybrid materials were incorporated into the unaged and rolling thin film oven (RTFO) hybrid asphalt binders were assessed. Furthermore, the central composite design (CCD) in the response surface methodology (RSM) were utilised to evaluate the effects of hybrid asphalt binder content and temperature on the rheological behaviour of the hybrid asphalt binders. Consequently, the hybrid asphalt binders showed dosage-dependent rheological behaviour, with the 6 % formulation exhibiting notably lower phase angle (δ) and complex shear modulus (G∗) than the control binder, particularly in the unaged state, while other dosages displayed more variable responses across the tested temperatures. The RTFO hybrid asphalt binders also revealed reduced stiffness across all temperatures compared to the control asphalt. Given that high correlation coefficients (R2) were demonstrated by the G∗ (<0.97) and δ (<0.93), a substantial relationship between the model values and the experimental data was identified. The optimal parameters (temperature and percentage) for the hybrid materials were also discovered to be 62.9 °C and 5.78 % using the numerical optimisation and the quadratic model. Considering that each response possessed a percentage error below 5 %, the effectiveness and the validation of the model were successfully verified in this study.

In this study, a novel inorganic Co-Apatite Phosphate substituted with cobalt ions (named CCP) of formula Co2Ca6(HPO4)(PO4)5(OH) was synthesized and evaluated for its multifunctional properties, encompassing corrosion inhibition, as well as antibacterial and antifungal activities. The synthesis process was conducted following a green chemistry approach and the phosphate compound was thoroughly analyzed using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDX), Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Electrochemical techniques were employed to investigate the corrosion prevention performance against carbon steel in two different hydrogen chloride acidic medium concentrations (5.0 M and 1.0 M HCl). The inhibitor demonstrates excellent performance in both mildly and highly acidic environments. In less corrosive environment of 1.0 M HCl, the inhibition efficiency is estimated to be 96.4 %, while under more corrosive 5.0 M HCl, the efficiency remains high at 90 %. In addition, biological assays revealed that the material exhibited notable antibacterial activity and antifungal effectiveness against both Gram-negative and Gram-positive. These results confirm the potentiality of CCP as a green multifunctional inhibitor effective in both harsh and microbially active environments (antimicrobial and antifungal).
在这项研究中，合成了一种新型无机钴离子取代钴离子的Co-Apatite磷酸盐（命名为CCP），其分子式为Co2Ca6(HPO4)(PO4)5(OH)，并对其多功能性能进行了评价，包括缓蚀，抗菌和抗真菌活性。采用绿色化学方法进行合成，并利用扫描电子显微镜、能量色散x射线能谱（SEM/EDX）、傅里叶变换红外光谱（FTIR）和x射线衍射（XRD）对磷酸化合物进行了全面分析。采用电化学技术研究了两种不同浓度氯化氢酸性介质（5.0 M和1.0 M HCl）对碳钢的防腐性能。该抑制剂在弱酸性和强酸性环境中均表现出优异的性能。在腐蚀性较弱的1.0 M HCl环境下，缓蚀率为96.4%，而在腐蚀性较强的5.0 M HCl环境下，缓蚀率仍高达90%。此外，生物实验表明，该材料对革兰氏阴性和革兰氏阳性菌均具有显著的抗菌活性和抗真菌活性。这些结果证实了CCP作为一种绿色多功能抑制剂的潜力，在恶劣和微生物活性环境（抗菌和抗真菌）中都有效。

The enhancement of heat transport in magnetohydrodynamic (MHD) nanofluid systems with exothermic chemical reactions is a growing area of interest for applications such as geothermal recovery, nuclear reactor thermal regulation, and advanced energy technologies. Despite extensive research, the complex roles of magnetic forces, nanoparticle suspensions, and chemical activity remain insufficiently clarified. This study presents a novel and comprehensive numerical analysis of buoyancy-induced magnetohydrodynamic (MHD) convection within a porous cavity filled with a CuO–water nanofluid, considering the combined influence of an external magnetic field and heat generation due to an exothermic chemical reaction. The findings offer new insights into coupled magneto-thermo-chemical transport phenomena in nanofluid-saturated porous media. The nanofluid and porous structure are modeled under the postulations of local thermal equilibrium. The derived principal transport equations are discretized and solved through a Galerkin extension of the finite element framework, which is validated against benchmark data. The simulations reveal several physical trends: thermal and velocity intensities increase significantly with higher Rayleigh numbers, resulting in larger Nusselt numbers. Quantitatively, the average Nusselt number () rises by 117% with increasing Rayleigh and Peclet numbers and by 15% for nanoparticle loading . In contrast, a strong magnetic field (), higher porosity, and reduce by 52%, 42%, and 26%, respectively, highlighting the competing influences of buoyancy, magnetic damping, porous resistance, and nanoparticle loading on heat transfer. Enhanced nanoparticle loading strengthens heat transport while reducing shear stresses and overall circulation strength. A stronger magnetic field suppresses both temperature and velocity gradients, limiting flow intensity, whereas its orientation plays a negligible role in frictional effects. Reaction-driven heating, characterized by the Frank–Kamenetskii parameter, substantially amplifies both velocity and heat transfer rates. At higher Péclet numbers, convective transport dominates over diffusive contributions. Furthermore, the porosity of the medium is shown to influence momentum and thermal transport, providing additional avenues for controlling flow resistance and enhancing thermal performance.
