From 1990 to 2024, this study presents a groundbreaking bibliometric and sentiment analysis of nanocomposite literature, distinguishing itself from existing reviews through its unique computational methodology. Developed by our research group, this novel approach systematically investigates the evolution of nanocomposites, focusing on microstructural characterization, electrical properties, and mechanical behaviors. By deploying advanced Boolean search strategies within the Scopus database, we achieve a meticulous extraction and in-depth exploration of thematic content, a methodological advancement in the field. Our analysis uniquely identifies critical trends and insights concerning nanocomposite microstructure, electrical attributes, and mechanical performance. The paper goes beyond traditional textual analytics and bibliometric evaluation, offering new interpretations of data and highlighting significant collaborative efforts and influential studies within the nanocomposite domain. Our findings uncover the evolution of research language, thematic shifts, and global contributions, providing a distinct and comprehensive view of the dynamic evolution of nanocomposite research. A critical component of this study is the “State-of-the-Art and Gaps Extracted from Results and Discussions” section, which delves into the latest advancements in nanocomposite research. This section details various nanocomposite types and their properties and introduces novel interpretations of their applications, especially in nanocomposite films. By tracing historical progress and identifying emerging trends, this analysis emphasizes the significance of collaboration and influential studies in molding the field. Moreover, the “Literature Review Guided by Artificial Intelligence” section showcases an innovative AI-guided approach to nanocomposite research, a first in this domain. Focusing on articles from 2023, selected based on citation frequency, this method offers a new perspective on the interplay between nanocomposites and their electrical properties. It highlights the composition, structure, and functionality of various systems, integrating recent findings for a comprehensive overview of current knowledge. The sentiment analysis, with an average score of 0.638771, reflects a positive trend in academic discourse and an increasing recognition of the potential of nanocomposites. Our bibliometric analysis, another methodological novelty, maps the intellectual domain, emphasizing pivotal research themes and the influence of crosslinking time on nanocomposite attributes. While acknowledging its limitations, this study exemplifies the indispensable role of our innovative computational tools in synthesizing and understanding the extensive body of nanocomposite literature. This work not only elucidates prevailing trends but also contributes a unique perspective and novel insights, enhancing our understanding of the nanocomposite research field.

“…In addition, cement is the most expensive material component of concrete, mainly because of its energy consumption during production [3,4,5]. Thus, the development of low carbon building materials, with equivalent physical and mechanical properties to the traditional concrete, is under constant constant research [6,7].…”

In view of the environmental impacts caused by the construction and agroindustry industries, the aim of this work is to evaluate the potential application of coffee husk ash (CHA) as a filling element in cement pastes. For this purpose, coffee husks and their ashes were characterized. Cement pastes, with a water-to-cement ratio of 0.4, were then produced with different amounts of CHA (5, 10, 15, 20 and 25% BWOC), burned at 600°C for 3 h, and characterized. The results showed that CHA had a high content of alkalis. A reduction in the amount and kinetics of calcium hydroxide formation was observed in the pastes. In the semiadiabatic calorimetry test, it seems that the increase in CHA content leads to hydration kinetic acceleration and an increase in the cumulative heat for up to 40 hours of hydration, indicating an effective filler effect caused by CHA.

“…A strategy to improve the properties of polymeric materials is the addition of a filler such as nanoclays, nano-oxides, cellulose nanocrystals, and organic fillers, among others, to obtain a new composite material [ 20 , 21 , 22 ]. The use of magnetic nanoparticles in different polymers has received great attention in recent years due to their non-toxic nature, biocompatibility, and the multiple applications that can be derived from the use of these materials, as well as the ease of their preparation [ 23 , 24 , 25 ]. Among them, magnetic polymer nanocomposites can be defined by the presence of a polymer matrix (organic) and a magnetic (inorganic) compound of nanometric size (e.g., nanoparticles) [ 26 ].…”

Renewable resources constitute an extremely rich and varied set of molecules and polymers produced by natural biological activities. Within the applications of these polymers, a very important application is the use of these materials as a sorber for oils or oil spills. The advantage of these nanocomposites is the fact that they integrate different component materials and their properties into a single component material. They have several applications, ranging from environmental remediation to the development of advanced medical applications. This work proposed using magnetic polyurea composites based on an animal substrate from Tenebrio molitor larvae to perform oil spill clean-up operations under a magnetic field in the presence of 1% and 3% of magnetite to be tested as magnetic crude oil sorber. The obtained materials were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Scanning Differential Calorimetry (DSC), and Low-Field Nuclear Magnetic Resonance (LF-NMR 1H). The sorber material is simple to prepare and inexpensive. The use of magnetite as a magnetic charge allowed for the efficient removal of oil from water with about 28 g of oil per gram of sorber. These results are very promising and encouraging for future environmental recovery studies involving magnetite and sustainable polymers.
