The increasing integration of green energy across various sectors aims to promote sustainable development and environmental protection. With advancements in microfabrication and microelectronics, there is a growing demand for microscale energy sources to power modern technologies, including implantable devices and portable electronics. Current portable devices primarily depend on conventional chemical batteries, leading to environmental contamination and resource depletion. In response, triboelectric nanogenerators (TENGs) have emerged as promising solutions for energy harvesting, utilizing the principles of electrostatic induction and triboelectrification to convert mechanical energy into electrical energy. This review focuses on developing biodegradable TENGs, particularly polylactic acid (PLA) and other biopolymers, which offer significant advantages due to their biodegradability, mechanical strength, and processability. By enhancing the output performance of TENGs through innovative design and the incorporation of nanomaterials, this study explores the potential of fully biodegradable devices fabricated using environmentally friendly methods, such as 3D printing and compression molding process. This approach not only addresses the challenges associated with electronic waste but also contributes to the advancement of sustainable energy solutions in the field of bioelectronics.

Heavy metals in various geochemical forms, such as exchangeable ions, carbonates, and oxides, pose significant risks to human health and the environment due to their persistence and bioaccumulation. Their mobility and toxicity depend on their chemical states, many of which are toxic, mutagenic, or carcinogenic. This study presents an innovative nanobiocomposite synthesized via hydrothermal methods, combining nickel oxide (NiO) and orange peel (OP) with alginate to create nickel-orange peel beads (Alg/OP-Ni). These beads exhibit exceptional adsorption capabilities for removing cadmium (Cd2⁺) and lead (Pb2⁺) ions, outperforming conventional materials. Characterization techniques such as FTIR, XRD, SEM, and EDS reveal a highly porous morphology due to NiO nanoparticle integration within the OP matrix, a structure that provides numerous active sites for adsorption. This innovative approach leverages agricultural waste, turning orange peels into a high-performance, eco-friendly adsorbent, thereby addressing both environmental pollution and waste management challenges.
Co-adsorption of Cd2⁺ and Pb2⁺ ions was investigated, focusing on pH, biomass dosage, contact time, initial concentration, and temperature. Adsorption data were modeled using Langmuir, Freundlich, and Dubinin-Radushkevich isotherms, indicating monolayer adsorption consistent with the Langmuir model. The adsorption mechanism involves a two-step process where positively charged Cd2⁺ and Pb2⁺ ions diffuse toward the negatively charged surface of the Alg-OP-Ni nanobiocomposite and subsequently fix through interactions with surface oxygen atoms. Maximum adsorption capacities for Cd2⁺ and Pb2⁺ were determined to be 138.25 and 276.00 mg/g in single-component systems, and 224.00 and 317.10 mg/g in binary systems, respectively. Kinetic studies suggest a pseudo-second-order model for the adsorption process. Tests with river water samples from Bétaré-Oya, Cameroon, confirm effective heavy metal removal, indicating the Alg/OP-Ni nanocomposite's potential as a sustainable solution for mining wastewater remediation. This study not only demonstrates the feasibility of using agricultural waste to create high-performance adsorbents but also highlights the significant advancements in adsorption technology for environmental remediation.

The aim of non-precious metal catalysts (NPMCs) is to replace expensive Pt-based catalysts for fuel cells. NPMCs require not only high oxygen reduction reaction (ORR) catalytic activity but also cheap ingredients and the facile synthetic method of the catalyst is amendable to mass production. We describe a potential catalyst for catalyzing the cathodic ORR, which is synthesized by a facile method: A graphene-polyaniline-iron nanoparticles/polyaniline-iron nanoparticles nanocomposite (Gr-PANI-Fe NPs/PANI-Fe NPs NCs) were prepared via a facile one-pot synthesis method involving chemical oxidative polymerization in acid medium. NCs are characterized for their morphology and microstructure by scanning electron microscope (SEM) with energy dispersive analysis of x-rays (EDAX), x-ray diffraction (XRD) analysis and x-ray photoelectron spectroscopy (XPS) analysis. Gr-PANI Fe NP NC and PANI-Fe NPs NC exhibited nanoflower (designated as GPF NF NC) and nanorod (designated as PF NR NC) like morphology, respectively. Herein, the synergistic influence of Gr and Fe NPs on PANI nanostructure was evaluated with analytical tools. Besides, the electrocatalytic performance of GPF NF NC/PF NR NC glassy carbon modified electrodes (GPF NF NC/PF NR NC GC-MEs) has been evaluated for their electrocatalytic performance towards oxygen reduction reaction (ORR) in acid environment. The electrocatalytic behavior is examined by the linear sweep voltammetry technique. It is found that the GPF NF NC GC-ME showed better performance when compared with PF NR NC GC-ME towards ORR. Both Gr and FeSO4 have predominant impact on the morphology of PANI chain. Such morphological influence reflects on efficiency of MEs in ORR process.

Fiber-reinforced composites are widely used in engineering applications due to their excellent physical and chemical properties. However, evaluating their flexural properties using conventional experimental techniques is time-consuming, costly, and limited by material and fabrication variations. This study investigates the potential of machine learning (ML) techniques to predict the flexural properties of fiber-reinforced composites accurately and efficiently. Five ML algorithms—Light gradient boosting regressor (LGBR), Extra tree regressor (ETR), Decision tree regressor (DTR), Histogram-based gradient boosting regressor (HGBR), and Adaptive boosting regressor (ABR)—were employed to predict the flexural strengths using both experimental data generated in-house and data collected from open literature. Including heterogeneous data from both sources enhances the robustness and generalizability of the developed models. The results demonstrate that the extra trees regressor (ETR) achieves excellent accuracy when applied to the heterogeneous dataset, with a coefficient of determination (R2) value of 0.94, MAE of 31.97, and RMSE of 47.64, outperforming the other three models. Furthermore, the in-house experimental data yields even higher prediction accuracy, with the best-performing model achieving an impressive R2 value of 0.99, MAE of 9.53, and RMSE of 13.15. The high prediction accuracy achieved, despite the slight variability in data obtained from the literature, highlights the potential use of ML techniques to streamline the development process and reduce the reliance on extensive experimental testing. These robust models take into consideration important composite production parameters to provide design engineers and research scientists with versatile and efficient tools for the prediction of flexural properties of fiber-reinforced composites and related materials for various industries, including aerospace, defense, energy, biomedical and automotive.

Mechanical and microstructural characterisation after different treatments of three new experimental micro-alloyed steels with vanadium for potential use as rail axles was undertaken. The quenched and tempered alloys had yield strengths from 668-1158 MPa and ultimate tensile strengths (UTS) from 880-1306 MPa. For the normalised and furnace-cooled alloys, the yield strengths were from 389-490 MPa with corresponding ultimate tensile strengths of 679–706 MPa. Although the strengths of the normalised and furnaced-cooled alloys were lower than the quenched and tempered, and the normalised in air alloys, they were higher than most of the standard conventional grades with minimum yield strength of 330 MPa and 600 MPa UTS. The quenched and tempered microstructures were mainly lath martensite and ferrite, with some bainite. All normalised and air-cooled steels, as well as the furnace-cooled 0.13 wt% V and 0.25 wt% V steels, were mainly bainite and ferrite. The normalised and furnace-cooled steels without V had banded ferrite-pearlite. The higher strengths of the quenched and tempered steels were due to the high proportions of martensite and bainite. The normalised and air-cooled and the normalised and furnace-cooled steels showed moderate strengths with elongations between 17% and 19% due to the ferrite-bainite or ferrite-pearlite microstructures. All steels with 0.13–0.25 wt% V had coarse microstructures but showed potential for rail axle applications due to superior mechanical properties than most standard grades.

Biodegradable implant materials are recommended to restore the bone injury and also to overcome the drawbacks of traditional metallic implants. PVC is still often utilized in the production of biomedical devices. This work explores the manufacture of an interlinked porous biomedical scaffold based on PVC using PEG and Chitosan (CS) polymers in order to examine the viability of PVC as a biomedical scaffold. PEG is added and contrasted with CS because it is hydrophilic in nature, non-toxic, antigenic, immunogenicity-free, and has a high level of biocompatibility. The produced scaffolds have undergone mechanical and thermal testing, biodegradability testing, FTIR analysis, and SEM analysis. The SEM pictures showed that the porous of PEG-PVC-2% SiO2 provides a larger surface area to prevent corrosion when compared to neat PVC. It demonstrated PEGplasticized PVC scaffolds developed micropores as a result of PEG enrichment from the PVC matrix. FTIR analysis shows the presence of functional groups. The maximum stress is 16.5 MPa is found for neat PVC sample; while adding PEG and CS reduced the strength due to the plasticizing effects. Silica filler have been added to PVC and PEG scaffolds to enhance the strength. Though silica improved the mechanical strength of PVC-PEG scaffolds, still it is 10 MPa, close to neat one. According to thermogravimetric analysis (TGA), there is no discernible weight loss below 100 °C. PEG decreased the thermal stability of PVC, according to thermal analysis from the DSC plot. The in vitro degrading process confirmed that the scaffolds were highly resistant to corrosion.

The in vitro degrading process confirmed that the scaffolds were highly resistant to corrosion.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"8 ","pages":"Article 100388"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143162164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main focus of the this research is to provide the numerical analysis of thermo-magnetic heat and mass transport features of two-dimensional radiative Prandtl-Eyring nanofluid flow over a stretching sheet with viscous dissipation, heat source/sink, Joule heating and chemical reaction effects. A novel Buongiorno's nanofluid model with gyrotactic microorganism concept is utilized to precisely describe the nano behaviour of Prandtl-Eyring fluid. However, this specific research problem has good number of applications in the various fields of science and engineering particularly in nanotechnology, electronic cooling, polymer processing, biomedicine, extruction polymer sheets and etc. Present physical problem results the coupled, nonlinear, two-dimensional, steady-state, partial differential equations and which are difficult to solve by using analytical methods. Hence, a robust matlab-based bvp4c numerical technique has been implemented to solve the present problem. The graphical illustrations showed that, the velocity profile decreased and temperature, concentration and microorganism profiles were elevated for the increasing values of magnetic number. Prandtl-Eyring nanofluid velocity decreased and temperature field enhanced with increasing Prandtl-Eyring parameters. Increasing Brownian motion parameter accelerates the temperature field and decreases the concentration profile. Skin-friction coefficient increases with increasing magnetic number. Microorganisms' density number increased with increasing Peclet number. The main objective of this investigation is the inclusion of Joule and viscous dissipation, thermal radiation, heat source/sink, inclined magnetic field, chemical reaction and gyrotactic microorganism effects with nanofluid model and this attempt generalizes earlier results and offers a novel re-defined numerical formulation of thermal and mass transportation properties of Prandtl-Eyring nanofluid flow over a stretching wall. In conclusion, the numerical accuracy of the present similarity solutions is validated with available results and observed an excellent agreement.

Fiber orientation within composite materials has a great impact on their physical and mechanical properties. This present research studied the impact of fiber orientation on the mechanical strength of chemically treated JUCO fiber-reinforced polymer composites. JUCO is a relatively new, robust fabric composed of a mixture of cotton and jute fiber in an equal weight ratio, where jute yarn is used as weft and cotton thread is used as wrap. It provides the best qualities of both fibers. It is very flexible and becoming increasingly popular because of its environment-friendly behavior. The composites were fabricated with variations in the jute fiber angle, including 0°, 30°, 45°, 60°, and 90°. Mechanical tests such as tensile, flexural, and impact tests were conducted to determine the effect of the fiber orientation on the composite properties under dry and pH 7 conditions. The durability and degradation due to water aging were investigated for around 120 days. The tensile and flexural results were justified by a finite element analysis (FEA). The highest tensile and flexural strengths (57.104 MPa and 84.67 MPa, respectively) were found when the direction of jute yarn in JUCO was at 0° towards the loading direction, while the 90° jute yarn orientation showed the lowest value of 21.042 MPa and 43.43 MPa, respectively.
