abstract = {Traditional cancer treatments, such as surgery, radiotherapy, and chemotherapy, are still the most effective clinical practice options. However, these treatments may display moderate to severe side effects caused by their low temporal or spatial resolution. In this sense, photonic nanomedicine therapies have been arising as an alternative to traditional cancer treatments since they display more control of temporal and spatial resolution, thereby yielding fewer side effects. In this work, we reviewed the challenge of current cancer treatments, using the PubMed and Web of Science database, focusing on the advances of three prominent therapies approached by photonic nanomedicine: (i) photothermal therapy; (ii) photodynamic therapy; (iii) photoresponsive drug delivery systems. These photonic nanomedicines act on the cancer cells through different mechanisms, such as hyperthermic effect and delivery of chemotherapeutics and species that cause oxidative stress. Furthermore, we covered the recent advances in materials science applied in photonic nanomedicine, highlighting the main classes of materials used in each therapy, their applications in the context of cancer treatment, as well as their advantages, limitations, and future perspectives. Finally, although some photonic nanomedicines are undergoing clinical trials, their effectiveness in cancer treatment have already been highlighted by pre-clinical studies.},

abstract = {Australian palm residues are generated by palm heart industry in large quantities and are considered an underused material with a composition rich in lignocellulosic structures. This residue is generally utilized as briquettes for energy or sheep feed; however, few works investigate this residue as composite fillers. This work aimed to revalue Australian palm residues (PR) by preparing polypropylene composites through melt mixing, using different fiber contents (0, 5, 10, 20, and 30 wt%), and evaluate the statistical influence of fibers (residues) alkali treatment (MPR) in composites mechanical properties. PR and MPR were evaluated by FTIR, XRD, SEM, TGA, and composites were assessed using thermal and mechanical analysis, in which ANOVA statistical analysis was applied. The residues addition increased the mechanical properties and their treatment enhanced the stiffness of the composites compared to pristine PP. However, ANOVA demonstrated that at low residues contents, surface treatment does not increase fiber-matrix interactions effectively, then tensile properties were statistically similar to PP. Considering tensile properties, 20% MPR showed statistically distinct properties, with significative enhancements; no filler contents dependence was verified. Flexural properties were more sensitive to residue loading, and composites with 30% PR and MPR presented superior mechanical performance. This difference is associated with a higher sensitivity of tensile stress towards fiber-matrix interactions, which was improved with fiber treatment. Also, the residues content and treatment influenced the composites' thermal stability, with better results for PP-MPR. Results indicate that palm residue is an excellent filler for improving composites' thermal and mechanical properties, with a greener character.},

abstract = {This work has analyzed the properties of thermoplastic starch (TPS)-minerals biocomposites and their degradation on water bodies. The TPS-minerals biocomposites were prepared from cassava peels, residual glycerin, and minerals [montmorillonite (MMT) and clinoptilolite (CLI)]. The TPS and TPS-minerals biocomposites were characterized by scanning electron microscopy (SEM), tensile tests, and contact angle measurements. Moreover, microcosm degradation tests evaluated the release of dissolved organic carbon content (DOC) and total nitrogen (TN), carbon/nitrogen ratio (C/N), and heterotrophic bacteria count (HBC) in order to simulate the environmental effects of these biocomposites disposal. The SEM results showed the appearance of whole starch grains in TPS, which is an indicative of a partial thermo-plasticization. Furthermore, it was observed a surface roughness in all samples, with a possible better dispersion of mineral particles for TPS-MMT. This fact indicates an improvement of the tensile strength and elongation at break, when compared to the TPS-CLI. Both TPS-MMT and TPS-CLI presented lower contact angle values than TPS. These characteristics may assist in the microorganism access to the surface, favoring the degradation and the release of carbon and nitrogen. Microcosm degradation tests revealed an increase in DOC release from 18 to 98 mg L−1 for TPS-CLI after 24 h. Besides, there was an increase in TN release to 200% for TPS-MMT and TPS and 500% for TPS-CLI. The HBC presented a high growth after 12 h of contact, especially for TPS (3.4 ± 0.2 log CFU mL−1). Therefore, the TPS-minerals (clinoptilolite/montmorillonite) promoted better surface properties to the biocomposites, by making them biodegradable on aquatic environments, without unbalancing the nutrient loads among different environmental compartments.},

abstract = {Technological advances related to the development of new sustainable materials have driven the search for composites containing green fillers. Polyurethane (PU) composites with natural fibers have stood out; however, these materials have limited mechanical and thermal properties. This study developed hybrid PU composites filled with ZnO and palm sheath residues and evaluated the fiber loading (0, 5, 10, 15, and 20 wt%) on morphological, chemical, thermal, crystalline, and mechanical properties. Microscopic and scanning electron microscopy images showed that ZnO promoted homogeneous and isotropic cell structures. Sheath palm residues were well dispersed throughout the PU matrix and increased the foam's density and further decreased the cell sizes due to limited expansion caused by the fibers that altered nucleation and growth mechanisms. Strong hydrogen bonds formed between the fillers and the PU matrix resulted in a new network that improved thermal resistance. Also, crystallinity enhanced PU chains' organization due to filler incorporation, and these changes on the PU matrix increased impact resistance. The best results were obtained for the hybrid PU composite with 20 wt% of palm fiber. The properties improvements show the reinforcements' character in PU foams with environmentally friendly materials.},
