Geopolymers offer an alternative to Portland cement, boasting high mechanical strength, as well as chemical and thermal durability. It is an inorganic polymer that has environmental advantages in its production, in addition to being considered a high-performance material. This study seeks to evaluate the mechanical properties of geopolymeric mortars reinforced with Carbon Nanotubes (CNT) as well as the method of incorporation into the mortar. CNTs are promising materials as reinforcements in geopolymeric matrices for the development of construction materials with specific applications aimed at better performance. The studied matrix results from the alkaline activation of metakaolin (MK) with sodium silicate and sodium hydroxide. CNTs were added in percentages of 0.1%, 0.3%, and 0.5% by mass of metakaolin. The evaluated properties for the resulting composite were compressive strength and flexural strength. Scanning Electron Microscopy (SEM) and Infrared Spectroscopy (FTIR) tests were carried out to evaluate the dispersion of CNTs in MK (before activation). The results show that when well distributed in the matrix, CNTs promote an increase in compressive and flexural strength of the samples.

Background/Objectives: Radiotherapy, radiobiology, and oncology have evolved rapidly over the past six decades. This progress has generated vast but fragmented bodies of scientific evidence. The present study aimed to systematically map and interpret their conceptual and temporal development using artificial intelligence (AI)-based methods. It highlights the integration between molecular mechanisms, clinical applications, and technological innovation within a precision radiotherapy framework. Methods: A corpus of 3343 unique articles (1964–2025) was retrieved from Scopus, PubMed, and Web of Science. Records were harmonized through deduplication, lemmatization, and metadata normalization. Topic modeling using Latent Dirichlet Allocation (LDA) and co-occurrence network analysis were applied to identify dominant research axes. Semantic and temporal analyses were conducted to reveal patterns, emerging trends, and translational connections across decades. Results: Three historical phases were identified. The first was a period of limited production (1964–1990). The second showed moderate growth (1991–2010). The third, from 2011 to 2024, represented exponential expansion, with publication peaks in 2020 and 2023. LDA revealed two principal axes. The first, a clinical–anatomical axis, focused on cancer sites, treatment modalities, and prognosis. The second, a mechanistic–molecular axis, centered on DNA repair, radiosensitivity, and biomarkers. Case synthesis from 2014–2025 defined five operational classes: DNA repair and molecular response; precision oncology and genomic modeling; individual radiosensitivity; mechanisms of radioresistance; and advanced technologies such as FLASH radiotherapy and optimized brachytherapy. Conclusions: AI-driven semantic and temporal analyses showed that radiotherapy has matured into an interconnected and interdisciplinary domain. The derived Precision Radiotherapy Implementation Plan translates molecular and computational insights into clinically actionable strategies. These approaches can enhance survival, reduce toxicity, and inform equitable health policies for advanced cancer care.

The development of thermally conductive and electromagnetic interference (EMI) shielding nanocomposites is becoming increasingly critical for next-generation electronic devices, where effective heat dissipation and high signal integrity are essential. This report summarizes a talk by Professor Sung-Ryong Kim from the Korea National University of Transportation, emphasizing structural design strategies—such as layered architectures, segregated structures, three-dimensional (3D) interconnected networks, and stretching-induced alignment—to enhance both thermal conductivity and EMI shielding effectiveness in polymer-based nanocomposites. By integrating nanofillers such as graphene fluoride (GF), MXene, and carbon nanotubes, Professor Kim’s work highlights how rational structural design can yield ultrathin films with thermal conductivity values up to 210 W/m·K and EMI shielding effectiveness (SE) reaching 62 dB under optimal filler contents. The strategies address not only GHz and THz frequency shielding demands but also practical industry concerns like cost, scalability, and mechanical robustness. Reflecting on potential future directions, Professor Kim underscored the promise of integrating artificial intelligence (AI) to expedite predictive material optimization, and he expressed enthusiasm for collaborating with computational scientists to guide advanced composites research. This convergence of data-driven modeling, sustainable polymer matrices, and industrial manufacturing constraints points the way to commercializable, high-performance thermoconductive EMI shielding solutions.
