“…In general, the GQDs enhances the mechanical properties around 2-3 fold whereas the rest of the nanofillers are capable of increasing the strength up to ~1.3 fold as shown in figure 37. This strengthening mechanism was first discovered by Lerf-Klinowski [212][213][214][215][216][217][218]. They proposed that oxidized graphene sheets (independent on the size of sheets) consist of -COOH and -C=O groups in their edges whereas other groups, such as epoxide and hydroxyls, are normally laid in the basal domains of the sheets [219][220][221].…”

The serendipitous discovery of carbon dots has been added as a new domain of interest for materials scientists due to their extraordinary photo-physical attributes and long-term colloidal stability. This domain was more nurtured when carbon dots meet macromolecular chains. Carbon dot confined polymer matrices have diversified because of their ease of fabrication and applications in sensing, optoelectronics, semiconductors, molecular delivery, and various commercial aspects. Most promisingly, very small amounts of carbon dots have a over-the-top synergistic outcome in the presence of macromolecular systems. This review encompasses the synthesis of carbons dots, their physical properties, various fabrication strategies of polymer-carbon dots nanocomposites and applications. TOPICAL REVIEW RECEIVED

“…During compression, longitudinal failure is closely linked to and controlled by the in-plane shear response of the composite [43]. The inhomogeneous dissipation of stress on the dual-material joint surface results in the peeling of the PLA and TPU bonding layers [44]. As a result, a few TPU layers were pulled out from the structure due to their high fracture elongation, and some energy was consumed through friction.…”

Auxetic re-entrant honeycomb (AREH) structures, consisting of a single soft or tough material, have long faced the challenge of balancing stiffness and rebound resilience. To achieve this balance, dual-material printing technology is employed to enhance shock absorption by combining layers of soft and tough materials. Additionally, a novel structure called the curved re-entrant honeycomb (CREH) structure has been introduced to improve stiffness. The selected materials for processing the composite structures of AREH and CREH are the rigid thermoplastic polymer polylactic acid (PLA) and the soft rubber material thermoplastic polyurethane (TPU), created utilizing fused deposition modeling (FDM) 3D printing technology. The influence of the material system and structure type on stress distribution and mechanical response was subsequently investigated. The results revealed that the dual-material printed structures demonstrated later entry into the densification phase compared to the single-material printed structures. Moreover, the soft material in the interlayer offered exceptional protection, thereby ensuring the overall integrity of the structure. These findings effectively serve as a reference for the design of dual-material re-entrant honeycombs.

“…Hydrogels can be categorized into two classifications: chemical hydrogels and physical hydrogels. Chemical hydrogels are chemically cross-linked hydrophilic polymer chains which are intermingled in a polymer matrix [ 74 ]. Sometimes these are also called covalent cross-linked hydrogels [ 73 , 75 , 76 ].…”

Hydrogels are spatially organized hydrophilic polymeric systems that exhibit unique features in hydrated conditions. Among the hydrogel family, composite hydrogels are a special class that are defined as filler-containing systems with some tailor-made properties. The composite hydrogel family includes magnetic-nanoparticle-integrated hydrogels. Magnetic hydrogels (MHGs) show magneto-responsiveness, which is observed when they are placed in a magnetic field (static or oscillating). Because of their tunable porosity and internal morphology they can be used in several biomedical applications, especially diffusion-related smart devices. External stimuli may influence physical and chemical changes in these hydrogels, particularly in terms of volume and shape morphing. One of the most significant external stimuli for hydrogels is a magnetic field. This review embraces a brief overview of the fabrication of MHGs and two of their usages in the biomedical area: drug delivery and hyperthermia-based anti-cancer activity. As for the saturation magnetization imposed on composite MHGs, they are easily heated in the presence of an alternating magnetic field and the temperature increment is dependent on the magnetic nanoparticle concentration and exposure time. Herein, we also discuss the mode of different therapies based on non-contact hyperthermia heating.
