A superior mix of big and small Graphene is often described as an unrolled carbon nanotube. However, although nanotubes are known for their exceptional mechanical conductivity properties, the same not true graphene-based fibers. Xin et al. intercalated fragments graphene into gaps formed by larger sheets that had been coiled Once annealed, large provided pathways conduction, while smaller helped reinforce The result? Superior thermal electrical strength. Science , this issue p. 1083
Organic phase change materials (PCMs) have been utilized as latent heat energy storage and release media for effective thermal management. A major challenge exists organic PCMs in which their low conductivity leads to a slow transient temperature response reduced transfer efficiency. In this work, 2D thermally annealed defect-free graphene sheets (GSs) can be obtained upon high annealing removing defects oxygen functional groups. As result of greatly phonon scattering centers transport, the...
With the increased use of data-driven approaches and machine learning-based methods in material science, importance reliable uncertainty quantification (UQ) predicted variables for informed decision-making cannot be overstated. UQ property prediction poses unique challenges, including multi-scale multi-physics nature materials, intricate interactions between numerous factors, limited availability large curated datasets, etc. In this work, we introduce a physics-informed Bayesian Neural...
The click-based interactive segmentation aims to extract the object of interest from an image with guidance user clicks. Recent work has achieved great overall performance by employing feedback output. However, in most state-of-the-art approaches, 1) inference stage involves inflexible heuristic rules and requires a separate refinement model, 2) number clicks model cannot be balanced. To address challenges, we propose mask-guided framework containing three novel components: Cascade-Forward...
Cs<sub>2</sub>SnI<sub>x</sub>Cl<sub>6−x</sub> perovskites were synthesized using hydriodic acid as an iodine source, and the color scheme displays a tunable band gap with varying I<sup>−</sup>/Cl<sup>−</sup> ratios.
Thermal transport is a key performance metric for thorium dioxide in many applications where defect-generating radiation fields are present. An understanding of the effect nanoscale lattice defects on thermal this material currently unavailable due to lack single crystal from which unit processes may be investigated. In work, series high-quality crystals exposed 2 MeV proton irradiation at room temperature and 600 °C create microscale regions with varying densities types point extended...
We report fabrication of a flexible, thorn-like ZnO-multiwalled carbon nanotube (MWCNT) hybrid paper with high aspect ratio for efficient ultraviolet (UV) sensing and photocatalyst applications.
Iodoapatite powder prepared by high‐energy ball milling is densified Spark Plasma Sintering to ~96% theoretical density. X ‐ray Diffraction and First‐principle Calculation indicates the sintered phase iodine‐deficient apatite with chemical composition of Pb 9.85 ( VO 4 ) 6 I 1.7 iodine confinement over 8 wt%. Thermogravimetric analysis shows bulk iodoapatite displays exceptionally stability without release until 670°C. The greatly improved can be attributed dense matrix upon rapid...
Abstract Organic-inorganic perovskite materials are revolutionizing photovoltaics with high power conversion efficiencies, but experience significant environmental degradation and instability. In this work, the phase stability decomposition mechanisms of lead-free all inorganic Cs 2 SnI 6 upon water moisture exposure were systematically investigated via in situ synchrotron X-ray diffraction, SEM, micro-Raman spectroscopy. A critical relative humidity (80%) is identified below which stable...
Abstract The early stage of microstructural evolution ThO 2 , under krypton irradiation at 600, 800, and 1000°C, was investigated using in situ transmission electron microscopy (TEM). Dislocation loops grew faster, whereas their number density decreased with increasing temperature. Loop found to decrease ion dose. Interstitial dislocation loops, including Frank Burgers vector a /3〈111〉 perfect /2〈110〉, were determined by traditional TEM atomic resolution–scanning techniques. Atomistic...
