Daily, vast amounts of waste are produced in the orange juice industry, a large part of which is reused in low-added-value products. In this work, orange vesicle fiber residues from the juice sieving stage were plasticized by extrusion, producing a thermoplastic citrus pulp (TCP). This pulp was incorporated into poly(butylene succinate) (PBS) at up to 50 wt %. The influence of TCP on the molar mass, morphology, tensile properties, rheological behavior, and biodeterioration of PBS in soil was evaluated. Highly flexible compounds with elongations similar to those of PBS were produced. Scanning electron microscopy analyses suggested good dispersion between the TCP and PBS phases, verified after acid extraction of pectin. Rheological analyses indicated the presence of strong interactions in the interconnected network formed by pectin gel, percolation of TCP lignocellulosic fibers, or both. Analyses of mass loss by burial in soil showed that the higher the TCP content in PBS is, the higher and faster the biodeterioration is. Size exclusion chromatography analyses indicated that the greater the concentration of TCP and the better dispersed it was in the compounds, the lower molar masses populations appeared in PBS, indicating higher rates of degradation of PBS in the presence of TCP. This innovative approach not only reuses the waste produced in the orange juice industry but also demonstrates the potential for obtaining environmentally friendly compounds.

For anodic aluminum oxide (AAO)-assisted anodization process, almost all metal oxide nanostructures are in the form of nanodots and nanorods, while tubular metal oxide nanostructures are rarely investigated. In this study, the anodized WO3 nanotubes with cap structures are successfully fabricated via AAO assistance in an anodization process. The height of the WO3 nanotubes is limited to ~180 nm by an electric field of 0.75 GV/m due to the dielectric breakdown effect, which is larger than the height of ~130 nm for the nanorods with 0.855 GV/m. The WO3 species is the dominant component at the top of the nanotubes, while the incomplete oxides such as W2O5, WOx, and even tungsten metal rule the elementss at the bottom. The bottom-up growth mechanism of the WO3 nanotubes is identified at the oxide/metal interface. The photoresponse of the WO3 nanotubes exhibits superiority under blue and UV light irradiation compared to the incompletely anodized WO3 nanorings, whereas opposite results are observed under red and green light irradiation. This result demonstrates that completely anodized structures facilitate exciton pumping, while incomplete oxides are conducive to low-energy excitons. The unique tubular metal oxide nanostructures are advantageous for designing various sensing devices, especially in optics. © 2024, The Authors. All rights reserved.

To date, the high cost of organic linkers and the energy-consuming synthesis processes remain two of the main challenges for the commercialization of metal-organic frameworks (MOFs). Herein, we demonstrate that polyethylene terephthalate (PET)-derived bis(2-hydroxyethyl) terephthalate (BHET) is a new linker source that enables the facile solvent-free and hydrothermal synthesis of BDC-based MOFs. Using BHET as a linker source, UiO-66(Zr) was rapidly synthesized via a solvent-free "grind and bake" technique, while Ca-BDC and Ba-BDC were easily obtained by using hydrothermal synthesis. We found that the hydrolysis of BHET to terephthalate anion (BDC2−) over proton produced from the hydrolysis/clustering of Zr precursor and hydroxyl anion produced from the dissolution of M(OH)2 (M = Ca or Ba) was the key to the crystal growth of solvent-free synthesized UiO-66(Zr) and hydrothermally synthesized M-BDC (M = Ca or Ba), respectively. While the as-synthesized UiO-66(Zr) was highly active for the esterification of lactic acid (LA) with ethanol (EtOH), Ca-BDC and Ba-BDC exhibited remarkable electrochemical performance for lithium storage. Our strategy provides a major step towards realizing the idea of a more facile, green, and low-cost synthesis of PET-derived MOFs compared to prior arts applicable for catalysis and energy applications. © 2024

High-cycle fatigue is a critical performance metric of structural alloys for many applications. The high cost, time, and labor involved in experimental fatigue testing call for efficient and accurate computer models of fatigue life. We present FIP-GNN – a graph neural network for polycrystals that (i) predicts fatigue indicator parameters as grain-level inelastic responses to cyclic loading quantifying the local driving force for crack initiation and (ii) generalizes these predictions to large microstructure volume elements with grain populations well beyond those used in training. These advances can make significant contributions to statistically rigorous and computationally efficient modeling of high-cycle fatigue – a long-standing challenge in the field. © 2024, CC BY.

Shredder residue (SR) is an inevitable waste in the production of steel by scrap melting, and the presence of chlorine is the main responsible for its non-use of energy. This study aimed to remove chlorine from SR by thermal dechlorination and water leaching. Thermal dechlorination was first studied from a PVC sample to evaluate the optimum parameters of temperature, heating rate, residence time and atmosphere (N₂ or steam). Under optimal conditions for PVC dechlorination, chlorine removals of 73.7 (N₂) and 68.0% (steam) were achieved. Optimal parameters were applied to thermal dechlorination of a Brazilian SR with a chlorine content of 2.12 wt%. Reductions in chlorine content to 0.95 and 0.51 wt% were observed with N₂ and steam atmospheres, respectively. In an additional evaluation (conducted also with the Brazilian SR and in order to investigate the reactor rotation effect), it was observed that the reactor rotation does not influence the release of chlorine during the thermal treatment but modifies the granulometry of the produced solid. Samples obtained from this test were subjected to a water leaching study to further reduce the chlorine content. The parameters studied were the type of water (tap and distilled), granulometry and carbonation (contact with CO₂) in a total of five washing cycles. Carbonation and use of distilled water achieved the highest chlorine removal resulting in a reduction of chlorine content from 1.13 to 0.45 wt%. The obtained results show directions for chlorine removal aiming at the energetic use of shredder residue. © 2024 The Authors

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

materials Discovery with Extreme Properties via Reinforcement Learning-Guided Combinatorial Chemistry

The goal of most materials discovery is to discover materials that are superior to those currently known. Fundamentally, this is close to extrapolation, which is a weak point for most machine learning models that learn the probability distribution of data. Herein, we develop reinforcement learning-guided combinatorial chemistry, which is a rule-based molecular designer driven by trained policy for selecting subsequent molecular fragments to get a target molecule. Since our model has the potential to generate all possible molecular structures that can be obtained from combinations of molecular fragments, unknown molecules with superior properties can be discovered. We theoretically and empirically demonstrate that our model is more suitable for discovering better compounds than probability distribution-learning models. In an experiment aimed at discovering molecules that hit seven extreme target properties, our model discovered 1,315 of all target-hitting molecules and 7,629 of five target-hitting molecules out of 100,000 trials, whereas the probability distribution-learning models failed. Moreover, it has been confirmed that every molecule generated under the binding rules of molecular fragments is 100% chemically valid. To illustrate the performance in actual problems, we also demonstrate that our models work well on two practical applications: discovering protein docking molecules and HIV inhibitors. © 2023, CC BY-NC-SA.
