Many studies show that hierarchical honeycombs have a superior performance compared to regular honeycombs. However, relevant experimental studies are limited due to the fabrication challenges of hierarchical honeycombs featuring complex geometries. In this study, circular-vertex-based hierarchical hexagonal honeycombs (CHHHs) with different hierarchical parameters were fabricated using a polymeric 3D-printing technique, and their quasi-static out-of-plane mechanical behavior was investigated. The CHHHs were constructed by replacing each solid vertex of a regular hexagonal honeycomb (RHH) with a circular vertex. Quasi-static compression tests were conducted on CHHHs, and the effect of the hierarchical parameter on the deformation modes, mechanical properties, and energy absorption characteristics was investigated. The results revealed that both the CHHH and RHH specimens experienced cell wall fractures during compression, while the CHHH exhibited enhanced damage resistance, compressive strength, and specific energy absorption (SEA) compared to RHH. This study contributes to understanding the effect of circular-vertex-based hierarchy on the out-of-plane mechanical behavior of regular honeycombs. Full article

With the rapid progression of industrialization, water pollution has emerged as an increasingly critical issue, especially due to the release of organic dyes such as methylene blue (MB), which poses serious threats to both the environment and human health. Developing efficient photocatalysts to effectively degrade these pollutants is therefore of paramount importance. In this work, titanium dioxide (TiO2) was modified with the photosensitizer hemin and the hydroxyl-rich polymer polydopamine (PDA) to enhance its photocatalytic degradation performance. Hemin and PDA function as photosensitizers, extending the light absorption of TiO2 into the visible spectrum, reducing its bandgap energy, and effectively promoting separation of photogenerated electron–hole pairs through conjugated structures. Additionally, the strong adhesion of PDA enabled the rapid transfer and effective utilization of photogenerated electrons, while its abundant phenolic hydroxyls increased MB adsorption on the photocatalyst’s surface. Experimental results demonstrated a significant enhancement in photocatalytic activity, with the 1%PDA/3%hemin/TiO2 composite achieving degradation rates of 91.79% under UV light and 71.53% under visible light within 120 min, representing 2.22- and 2.05-fold increases compared to unmodified TiO2, respectively. This research presents an effective modification approach and provides important guidance for designing high-performance TiO2-based photocatalysts aimed at environmental remediation. Full article

The adhesive–resin composite pair has been the cornerstone of direct restorations in dentistry for many years. Resin composites are traditionally classified in three ways based on their inorganic structure, their organic composition and their viscosity. While these classifications have long been associated with the optical, mechanical, and clinical properties of resin composites, recent studies indicate that this classification is not always valid. In recent years, a significant expansion of the range of clinical resin composite families has occurred, each with varying degrees of validation through in vitro and clinical studies. As a result, new resin composites with distinct structures, viscosities, and clinical indications have emerged. Despite this progress, a formal classification of the clinical features of all resin composites is still lacking, leading to terminological inconsistencies in research and potential confusion among clinicians. This brief review, supported by an exhaustive search of the dental literature, proposes a new clinical classification system for resin composites based on their key clinical features to help clinicians and researchers easily identify the key clinical characteristics of formulations. This modular classification, encompassing eight main families and 14 characteristics, is particularly suited to future developments, as current trends aim to simplify procedures by integrating multiple formulations into single products.
