We present AnisoGNNs - graph neural networks (GNNs) that generalize predictions of anisotropic properties of polycrystals in arbitrary testing directions without the need in excessive training data. To this end, we develop GNNs with a physics-inspired combination of node attributes and aggregation function. We demonstrate the excellent generalization capabilities of AnisoGNNs in predicting anisotropic elastic and inelastic properties of two alloys. © 2024, CC BY.

We present a transcriptomics pipeline for performing the functional analysis of array expression profiling data of normal and adenocarcinoma lung tissue. Our aims are twofold, firstly to elucidate molecular processes that transform normal tissue, to a lung adenocarcinoma. Following this, we perform functional analysis to screen potential hub genes and demonstrate their value in cancer prognosis. Analysis was performed on a total of 500 differentially expressed genes (DEG), screened for their regulation and transcriptional modulation in a female population carrying non–small cell lung carcinoma (NSCLC). Key pathways like cytokine-cytokine receptors, ECM receptor interactions, and TNF signaling were identified suggesting a potential role in lung tumorigenesis. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Due to extraordinary electronic and optoelectronic properties, large-scale single-crystal two-dimensional (2D) semiconducting transition metal dichalcogenide (TMD) monolayers have gained significant interest in the development of profit-making cutting-edge nano and atomic-scale devices. To explore the remarkable properties of single-crystal 2D monolayers, many strategies are proposed to achieve ultra-thin functional devices. Despite substantial attempts, the controllable growth of high-quality single-crystal 2D monolayer still needs to be improved. The quality of the 2D monolayer strongly depends on the underlying substrates primarily responsible for the formation of grain boundaries during the growth process. To restrain the grain boundaries, the epitaxial growth process plays a crucial role and becomes ideal if an appropriate single crystal substrate is selected. Therefore, this perspective focuses on the latest advances in the growth of large-scale single-crystal 2D TMD monolayers in the light of enhancing their industrial applicability. In the end, recent progress and challenges of 2D TMD materials for various potential applications are highlighted. © 2023 The Authors. Advanced science published by Wiley-VCH GmbH.

Polyetheretherketone (PEEK) Implant Functionalization with Magnetron-Sputtered SrTiO3 for Regenerative Medicine

Polyetheretherketone (PEEK) is a polymer widely used for artificial bone implants but exhibits a low affinity for bone tissue and lacks osteoconductivity and osseointegration. Because strontium (Sr) is known to enhance bone growth, PEEK implants coated with strontium titanate [SrTiO3 (STO)] are expected to improve the bone growth around them. In this study, STO was deposited on model PEEK implants by magnetron sputtering deposition and its ability to release Sr2+ ions to a surrounding phosphate-buffered saline (PBS) solution was examined. It was found that, in the early stage of the deposition process, STO on a PEEK surface exhibits irregular surface structures with many holes. The amount of Sr stored in the STO film increases with the increasing film thickness but the release rate of Sr2+ ions from the STO film to the surrounding PBS also increases with the film thickness, limiting the duration of effectiveness of the STO-coated PEEK films. It was found, however, that a three-layer titanium (Ti)-STO-Ti film deposited on PEEK allows a steady release of Sr2+ ions to the surrounding PBS for an extended period. © 2023 by Begell House, Inc. ***.

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.

PET-derived bis(2-hydroxyethyl) terephthalate as a new linker source for solvent-free and hydrothermal synthesis of BDC-based MOFs

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

FIP-GNN: Graph neural networks for scalable prediction of grain-level fatigue indicator parameters

arXiv

arXiv 2024年

作者： Sim, Gyu-Jang Lee, Myoung-Gyu Latypov, Marat I. Department of Materials Science and Engineering & RIAM Seoul National University 1 Gwanak-ro Gwanak-gu Seoul08826 Korea Republic of Department of Materials Science and Engineering University of Arizona TucsonAZ85721 United States Graduate Interdisciplinary Program in Applied Mathematics University of Arizona TucsonAZ85721 United States

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.
