N, S-co-doped carbon dots (N, S-CDs) were synthesized from Calotropis gigantea leaves via a green hydrothermal method and used as dual-function reducing and stabilizing agents for the in situ fabrication of Ag-Fe bimetallic nanocomposites (Ag-Fe@N, S-CDs). Thus, this study presents a sustainable nanoplatform that combines heteroatom-doped carbon dots with bimetallic systems without the use of external chemical reducing agents. The N, S-CDs exhibited effective antioxidant activity with IC₅₀ values of 39.17µg mL⁻¹ (DPPH), 42.26µg mL⁻¹ (FRAP), and 15.30µg mL⁻¹ (ABTS). In contrast, Ag-Fe@N, S-CDs showed improved anti-inflammatory activity with albumin denaturation inhibition of 59.48-77.38% and proteinase inhibition up to 93.63%, along with enhanced cytotoxicity against MCF-7 cells (IC₅₀ = 90.15µg mL⁻¹). Both nanomaterials exhibited effective antimicrobial activity with minimum inhibitory concentration (MIC) values ranging from 31.25 to 250µg mL⁻¹ against tested pathogens. These results indicate that N, S-CDs are more effective as antioxidant agents due to their rich surface functional groups, whereas Ag-Fe@N, S-CDs show superior anti-inflammatory and cytotoxic performance due to synergistic interactions between the metal components and the carbon framework. Therefore, the present study revealed a green and efficient strategy for designing multifunctional nanocomposites with potential biomedical applications.

A novel approach is introduced for detection of pendimethalin (PEN) -one of the most widely utilized herbicides- based on the synergistic properties of molecularly imprinted polymers (MIPs) and a CuO-Bi2MoO6 (Cu-Bi-Mo) nanocomposite. The methodology combined the specific recognition capabilities of MIPs with the enhanced sensing performance provided by the advanced nanocomposite material. The synthesis of the Cu-Bi-Mo nanocomposite was initiated through the application of the sol-gel method. After the glassy carbon electrode's modification with the Cu-Bi-Mo nanocomposite, PEN imprinted electrodes were fabricated using cyclic voltammetry (CV) with a dispersion containing 100.0 mM pyrrole (Py) monomer and 25.0 mM PEN molecule. The electrochemical sensor revealed a detection range of 1.0 × 10- 9 M to 1.0 × 10- 8 M PEN and achieved a detection limit (LOD) of 3.30 × 10- 10 M. To demonstrate its practical applicability, the electrochemical sensor was applied to drinking water and orange juice samples, yielding recovery results near 100%. This high recovery indicated the exceptional precision and reliability of the proposed electrochemical sensor. The electrochemical sensor's performance was thoroughly assessed across several key metrics including selectivity, stability, and reproducibility.

High-efficiency energy storage technologies have become particularly crucial with the ever-increasing demand for energy in recent years. Research on polymer nanocomposite dielectric materials has emerged as a prominent focus. Particularly, there is an urgent demand for the development of advanced dielectric film materials that exhibit superior energy storage performance over a wide temperature range. To this end, this study aims to investigate the effect of the molecular weight of reduced polyaniline (R-PANI) on the dielectric properties of all-organic composite films based on high-temperature-resistant polyetherimide (PEI). All-organic R-PANI/PEI composite films were fabricated by blending PEI matrix with R-PANI of varying molecular weights. Through combined density functional theory (DFT) calculations and experimental measurements, the blocking mechanism of R-PANI on charge carrier migration within the composite films was elucidated, showing a significant enhancement in the discharge energy density of PEI polymers while maintaining high charge–discharge efficiency. With charge–discharge efficiency maintained above 95%, R-PANI3/PEI achieved a discharge energy density of 2.36 J cm−3 at room temperature, nearly double that of pristine PEI (1.2 J cm−3). At 150 °C, the 1.0 wt% R-PANI3/PEI composite film retained a discharge energy density of 2.27 J cm−3 with a charge–discharge efficiency of 89.2%, outperforming pure PEI (1.1 J cm−3, 85.1%). These findings provide a new strategy for the design of all-organic composite dielectric films and demonstrate the potential of R-PANI in the application of high-performance capacitors and electrical energy storage.

Functional nanocomposites have emerged as a transformative class of materials for advanced energy and electronic applications due to their ability to integrate multiple functionalities within engineered nanoscale architectures. This review provides a comprehensive analysis of the fundamental principles governing nanocomposite behavior, including classification frameworks, commonly employed nanofillers, and critical structure–property relationships. Emphasis is placed on interfacial interactions, dispersion quality, percolation phenomena, and anisotropic effects that dictate electrical, thermal, mechanical, and electrochemical performance. State-of-the-art synthesis and fabrication strategies—ranging from solution-based and melt-processing techniques to vapor-phase deposition and additive manufacturing—are systematically examined in relation to microstructural control and scalability. The multifunctional properties of nanocomposites are critically evaluated, highlighting their relevance in energy storage systems, energy conversion technologies, flexible electronics, sensors, and electromagnetic interference shielding. Key challenges, including nanofiller agglomeration, interfacial compatibility, long-term stability, cost, and sustainability considerations, are discussed alongside emerging solutions. Finally, future perspectives focusing on next-generation nanofillers, AI-assisted materials design, and sustainable manufacturing pathways are outlined, providing a roadmap for the rational development and industrial translation of high-performance multifunctional nanocomposites. The scope of this review is deliberately focused on materials-level structure–process–property relationships in functional nanocomposites, rather than on detailed device-level electronic design or application-specific electromechanical implementations.

2,5-Dimethylfuran (2,5-DMF), a renewable biofuel with promising properties, highlights the importance of biomass conversion as a key strategy for sustainable energy production. In this study, we report a facile synthesis of 2,5-DMF from 5-chloromethylfurfural (CMF) using polymer-supported nano-composite material (Pd@PS) as a catalyst at 35°C in 3 h under a H2 atmosphere. The developed methodology provides an excellent tentative carbon conversion efficiency percentage (90%), high atom economy (64%), and low environmental factor (E-factor) (1.15, normalized value 50%), indicating sustainability and a green chemistry matrix. These studies also aligned with the UN Sustainable Development Goals 7 and 12, contributing to the global transition toward cleaner and more sustainable chemical manufacturing by valorizing biomass-based feedstocks. Additionally, the CMF has been synthesized from raw biomass sources, like banana peel waste, sugarcane bagasse, rice straw, and corn cobs, with yields ranging from 8 to 15 wt% and carbon conversion efficiency (tentative) between 25% and 54%. Furthermore, the developed protocol offered an efficient and scalable process (up to 5.0 g) for the production of biofuel, with superior catalytic activity and high recyclability up to six cycles. Moreover, total turnover and turnover frequency numbers were found to be 59.89 and 59.89 h-1, respectively.

Water invasion has become a critical challenge during the late-stage development of gas reservoirs, particularly under harsh conditions characterized by high temperature, high salinity, and strong reservoir heterogeneity. Chemical water shutoff technologies have thus gained increasing attention as effective solutions for selectively restricting water production while preserving gas deliverability. This review systematically summarizes recent advances in chemical water shutoff for gas reservoirs, focusing on polymer gels, nanocomposite materials, relative permeability modification agents, and emerging functional fluids. The reviewed materials are analyzed in terms of dominant sealing mechanisms, gas-water selectivity, reservoir adaptability, and performance under extreme formation conditions. By critically comparing their advantages, limitations, and field applicability, key challenges related to deep placement, selective sealing, long-term stability, and engineering controllability are identified. To address these limitations, emerging concepts such as zonal synergistic water control and bioinspired gas-water barriers are discussed, integrating wettability regulation, multiscale sealing, and adaptive material responses. These strategies provide a conceptual framework and research direction for the design of next-generation, efficient, and sustainable chemical water shutoff systems in complex gas reservoirs.

A review on polymeric and nanocomposite materials for heavy metal removal from water: bibliometric analysis

In the pursuit of sustainable and flexible electronics, polymer-based conductive films offer a promising solution due to their biodegradability, mechanical flexibility, and cost-effective fabrication. This study presents the development of a highly conductive and flexible nanocomposite material based on polyaniline-grafted chitosan (PANI-g-Chs) and Vinavil (Vi, a vinyl glue specifically designed for enhancing the sealability of textiles and paper), serving as a matrix for applications in flexible electronics. The PANI-g-Chs nanocomposite was synthesized via in situ oxidative polymerization, where chitosan nanoparticles (Chs) served as a stabilizing template to prevent PANI aggregation, reducing the particle size from 1700 nm (pristine PANI) to 180 nm (PANI-g-Chs). The resulting composite exhibited exceptional electrical conductivity (77.79 S/m at 25 wt% PANI-g-Chs). Hall effect measurements showed that the carrier mobility increased up to 1162.7 cm2/V·s and the carrier density rose to 6.5.1017 cm−3, confirming efficient charge transport and network formation. Mechanical analysis revealed a 300% increase in the storage modulus for PANI-g-Chs, and thermal studies confirmed stability up to 300 °C. Optical characterization showed a reduced bandgap (3.6 eV) and extended π-conjugation, which are critical for optoelectronic applications. Application tests demonstrated stable conductivity under mechanical deformation, highlighting the material’s potential for use in flexible electronics, sensors, and sustainable conductive coatings. This work offers a viable alternative to conventional conductive polymers.

Abstract This study investigates the influence of multiwalled carbon nanotubes (MWCNT), as reinforcement in the AlSi9Cu3(Fe) matrix, for production of metal nanocomposite material. AlSi9Cu3(Fe) alloy found special application in the automotive industry using high pressure die casting (HPDC) process. The main goal of the experiment was development of a nanocomposite material that can achieve significant decrease in the vehicle mass, which will have a positive impact on fuel consumption and general CO 2 emission into the atmosphere. Three different states of nanocomposite material were investigated: casted, naturally, and artificially aged. The produced nanocomposite was analyzed using an optical emission spectrometer and carbon–sulfur (CS) elemental analyzer to determine the chemical composition and presence of MWCNT. Tensile strength testing was carried out on the universal static testing machine, and both optical and scanning electron microscopy were used for microstructure analyses, followed by energy-dispersive X-ray spectroscopy (EDS) analysis of main microstructural constituents. A significant increase in tensile strength after 3 years of the natural aging process is caused by precipitation hardening and the occurrence of a great number of extracted small intermetallic precipitates and a more homogeneous distribution of MWCNT in the metal matrix. The heat treatment for artificial aging process has shown an insignificant increase in tensile strength in comparison with the natural aging process.

ABSTRACT A sunlight-activated photocatalyst that is environmentally friendly and harmless to the surrounding environment could serve as an appropriate choice for wastewater treatment approaches. In the present research, we strengthened TiO2 by employing Carbon Quantum Dots (CQDs) in order to enhance their photocatalytic efficiency and circumvent their efficiency restrictions. Upon thoroughly investigating the TiO2@CQDs hybrids’ morphological characteristics, framework, and other capabilities, it became obvious that the CQDs and TiO2 were both properly merged. When the TiO2CQDs nanocomposite material was implemented in lieu of unaltered CQDs, the photodegradation of Malachite Green dye (MGD) under solar radiation displayed a spike in reaction rate. The nanocomposite’s potential to capture sunlight was substantially enhanced by doping, which additionally improved interfacial charge transfer and segregation. The involvement of active species in the decay of MGD was determined as well by a radical scavenging test. The key attributes that increased the appealing factor of CQDs and TiO2@CQDs nanocomposite with regard to photocatalytic potential were their economic fabrication and environmentally benign reagents.
