“…Conversely, the activated carbon samples displayed a distinct degradation with a greater degree of surface roughness compared to hydrochar. Specifically, the rough surface of activated carbon displayed a higher density of external holes and cracks, indicative of the enhanced decomposition of cellulose, hemicellulose, and lignin in line with prior research . For hydrochar-infused PETG samples, HC-PETG30 and HC-PETG50 exhibited holes and cracks on the surface, indicating damage to the polymer matrix.…”

Fused deposition modeling (FDM) 3D printing not only offers numerous advantages over traditional manufacturing methods but also produces a significant amount of waste in the form of failed prints, support structures, and unused filaments. Thus, there is a need to develop novel and sustainable materials to replace conventional FDM filaments. We report a unique biomass (waste leaves)-derived activated carbon that can be infused with polyethylene terephthalate glycol (PETG) to fabricate a sustainable, cost-effective, and eco-friendly class of 3D printing filaments that enable 3D printing of parts with superior mechanical properties. We investigate the key parameters that influence the chemical, morphological, thermal, surface, and mechanical properties of our biomass-derived hydrochar, activated carbon, and PETG composite filaments. The resulting samples are characterized using Fourier transform infrared spectroscope, X-ray diffraction, scanning electron microscope, contact angle meter, and a universal testing machine. We have observed that while hydrochar can be incorporated with PETG to create biomass-derived filaments, incorporating activated carbon with PETG results in superior filaments. These composites can incorporate an extremely high biomass filler weight percentage while enhancing mechanical strength by over 30%. Our biomass-derived PETG composites were also thermally stable and more hydrophilic than the pure PETG samples. We analyze the mechanism by which activated carbon incorporation increases the PETG composites’ mechanical strength with both physical and chemical techniques. We also demonstrate successful FDM 3D printing of personalized anatomical models and porous cylindrical filter mesh using our biomass-derived PETG composite filaments. Implementing such sustainable principles in the 3D printing industry has the potential to transform it into a restorative and sustainable system while simultaneously minimizing environmental pollution and waste.

“…Similarly, photothermal studies on carbon dots (in the solvent dispersed state) have resulted in a thriving area of photocatalytic and photocaged reactivity. 31,32 Based on these results, the adsorption and sensing mechanism of the 3D fluorescent hydrogel CMH-NCDs for UO 2 2+ is systematically given in Fig. 6d.…”

“…When UO 2 2+ ion solution enters the CMH-NCD material, the UO 2 2+ ions undergo specific binding with the N-H and CO group, accompanied by extremely weak emission or almost no emission, which means that the radiant energy absorbed by the NCDs relaxes through nonradiative paths, resulting in light-to-heat transduction in the material. 32 In other words, the photoexcited electrons in the NCDs lack a radiative de-excitation pathway, thus causing them to lose their energy non-radiatively to relax back to the ground state, leading to the temperature generated. Therefore, the 3D porous fluorescent hydrogel exhibits excellent adsorption capacity for UO 2 2+ .…”

Carbon dots are zero-dimensional nanomaterials that have garnered significant research interest due to their distinct optical properties, biocompatibility, low fabrication cost, and eco-friendliness. Recently, their light-to-heat conversion ability has led to several novel photothermal applications. In this minireview, we categorize and describe the photothermal application of carbon dots along with methods incorporated to enhance their photothermal efficiency. We also discuss the possible mechanisms by which the photothermal effect is realized in these carbon-based nanoparticles. Taken together, we hope to provide a comprehensive landscape highlighting several promising research directions for using carbon dots for photothermal applications.
