Improving supercooled liquid water representation in the microphysical scheme ICE3
Authors: Dupont Rémi , Taymans Claire , Vié Benoît 
Published: July 2024

AbstractMost numerical weather prediction (NWP) models have a significant bias in predicting supercooled liquid water (SLW). For this reason, icing risk diagnostic tools do not use supercooled liquid water forecast by the models as an input parameter, but rather temperature and humidity, which are forecast better than SLW. The main objective of this study is to improve the SLW representation in the microphysical scheme ICE3 (Three Ice categories) used in the operational Applications de la Recherche à l'Opérationnel à Méso‐Echelle (AROME) model. For this purpose, several parametrizations of the microphysical processes were evaluated to find a better representation of SLW in the Mesoscale Non‐Hydrostatic model (MESO‐NH), which also uses ICE3. Elements of the microphysical scheme of the HARMONIE‐AROME model and work carried out by the Centre National de Recherches Météorologiques (CNRM) have been tested and compared with the current scheme. After a preliminary study, three parametrizations of the microphysical scheme were selected, in which the processes of ice initiation, snow and graupel collection of cloud droplets, condensation, Bergeron–Findeisen, and saturation adjustment were modified. Then, MESO‐NH simulations were performed and compared with observations from the In‐Cloud ICing and Large‐drop Experiment (ICICLE) airborne campaign. Three case studies were used with different icing weather conditions such as freezing rain, freezing drizzle, lake effect, etc. The results show a better representation of SLW with a greater presence of cloud droplets for colder temperatures up to 30 C. However, the liquid water content remains underestimated and the ice mass is overestimated. The ice initiation and cloud droplet collection by snow and graupel play a major role in the SLW representation. Parametrizations with restrictive ice initiation criteria reduce cloud droplet consumption and provide better agreement with observations. The results are promising and need to be investigated further with more cases and in the operational model AROME.

Published: July 2024

AbstractAs the rising renewable energy demands and lithium scarcity, developing high‐capacity anode materials to improve the energy density of potassium‐based batteries (PBBs) is increasingly crucial. In this work, a unique orderly multilayered growth (OMLG) mechanism on a 2D‐Ca2Si monolayer is theoretically demonstrated for potassium storage by first‐principles calculations. The global‐energy‐minimum Ca2Si monolayer is a semiconductor with isotropic mechanical properties and remarkable electrochemical properties, such as a low potassium ion migration energy barrier of 0.07 eV and a low open circuit voltage ranging from 0.224 to 0.003 V. Most notably, 2D‐Ca2Si demonstrates an ultrahigh theoretical specific capacity of 5459 mAh g−1 and a total specific capacity of 610 mAh g−1, reaching up to 89% of the capacity of a potassium metal anode. Remarkably, the OMLG mechanism facilitates stable, dendrite‐free deposition of hcp‐K metal layers on the 2D‐Ca2Si surface, where the ultrahigh and gradually converging lattice match as the layers increase is the key to achieving theoretically near‐infinite growth. The study theoretically demonstrates the Ca2Si monolayer a highly promising anode material, and offers a novel potassium storage strategy for designing 2D anode materials with high specific capacity, rapid potassium‐ion migration, and good safety.

Published: July 2024

AbstractOrganic single crystals possess distinct advantages due to their highly ordered molecular structures, resulting in improved stability, enhanced carrier mobility, and superior optical characteristics. However, their mechanical rigidity and brittleness impede the applications in flexible and wearable optoelectronic devices. Here, photoluminescence (PL) emission from 2,6‐diphenylanthracene (DPA) single crystals is studied under tensile strain, which shows PL enhancement by more than two times with a strain of ≈1.42%. Such a tension induced PL enhancement is reversible, exhibiting no clear optical degradations during 100 cycles of bending and recovery processes. Theoretical calculations reveal that the deformation of molecular structure under strain induces a decrease of the dihedral between anthracene and benzene moieties in DPA molecules. Further, the increased molecular conjugation enhances the molecular oscillator strength, leading to the brightened PL emission. Meanwhile, with the decreased dihedral, the molecular vibrations in DPA crystals are suppressed, which can reduce the non‐radiative decay rate. In contrast, no tension induced PL enhancement is observed in polycrystalline DPA thin films as the strain can be released via the grain boundaries. This study highlights the superior optical performance of DPA single crystals under strain field, which will provide new possibilities for DPA‐based flexible devices.
Flexible Mesopores in Nanoscrolls: Extraordinarily Large Alteration of Pore Sizes and Their Reversibility
Authors: Asakura Yusuke , Leung Mandy H. M. , Yamauchi Yusuke 
Published: July 2024

AbstractFlexible porous materials have gained considerable interest for their potential applications in selective absorption and controlled release/storage of specific molecules or compounds. Here, nanoscrolls are proposed as a type of inorganic solids with reversibly flexible mesopores. Nanoscrolls exhibit a rolled‐up structure composed of nanosheets with a 1D rod‐like morphology, possessing two distinct nanospaces. The first space comprises 1D tubular mesopores located at the center of the rod, while the second space exists in the interlayer regions on the wall of the mesopore, resulting from the layer stacking caused by the scrolling of nanosheets. By replacing the interlayer cations on the nanoscroll walls with other cations, a drastic alteration in the size of the 1D mesopores is observed. For instance, exchanging bulky dodecylammonium cations with small NH4+ cations leads to a substantial change in pore size, with differences ranging from 10 to 20 nm—a notably larger variation compared to previous reports on flexible porous materials. Importantly, the alteration of pore size induced by the exchange reaction is found to be reversible. This reversible alteration in pore size holds promise for applications in host–guest chemistry involving large moieties such as nanoparticles and enzymes.

Published: July 2024

AbstractAmong the lead halide perovskite (LHP) family, CsPbI3 is known to be significantly vulnerable to moisture, which hinders its use in real device applications. It is reported that chalcogen‐based ligands can better stabilize CsPbI3 and revive nanocrystals (NCs). Here, diphenyl diselenide (DPhDSe) ligand is used to revive the degraded CsPbI3 NCs through a post‐synthetic treatment of adding a small amount of DPhDSe in the degraded NC dispersion. DPhDSe in the dispersion formed nanofibrillar crystals at a low temperature through the π–π stacking of the phenyl ring. The nanofibrils played as a template on which the NCs self‐assembled and they are attached side‐by‐side to form microfibers. The microfiber powder containing the NCs is optically stable at ambient conditions and morphologically self‐healable by mild thermal annealing due to the dynamic Se─Se bond. The mechanism of the structural changes, optical transitions, and chemical changes has been systematically characterized through electron microscopy, diffraction, spectroscopy, and elemental analysis.

AbstractThe instability to moisture, heat, and ultraviolet (UV) light is the main problem in the application of quantum dot solar cells (QDSCs). Thin film encapsulation can effectively improve their operational stability. However, it is difficult to achieve multiple barrier effects with single layer of encapsulated film. Here, a hybrid thin‐film encapsulation strategy is reported to encapsulate lead sulfide QDSCs, which can isolate moisture and partial thermal, and prevent the penetration of UV light, thus retarding the surface oxidation process of the quantum dots. After 60 h, the encapsulated device retains a normalized power conversion efficiency of 83.8% and 80.6% at 85% humidity and 75 °C, respectively, which is three and six times of the value obtained in unencapsulated devices. At continuous UV illumination, encapsulated device exhibits five times higher stability than the reference. This strategy provides the way for the overall improvement of the operating stability of lead sulfide QDSCs in harsh environments of high humidity, high temperature, and UV light.

Published: July 2024

AbstractDistributed fiber optic sensors (DFOS) allow for the measurement of distributed strains on concrete surfaces and along steel reinforcement in reinforced concrete (RC) members, and these measurements can quantify reinforcement and concrete behavior. In this investigation, concrete surface and reinforcement strains from DFOS were used to quantify and compare the structural behavior of lightly and moderately reinforced one‐way slabs strips to better characterize localized strain behavior of lightly reinforced RC members with small diameter bars (10 M). By quantifying the entire compression region and reinforcement strain behavior, various structural parameters, such as curvature, strain profiles over the height at various locations, and neutral axis depth were calculated. From the distributed properties, it was determined that significant differences in behavior existed between moderately and lightly reinforced specimens with small diameter bars, with the lightly reinforced specimen displaying non‐uniform behavior along its length. Differences observed in the lightly reinforced member with small diameter bars include local curvature differences both at a crack and between cracks, local evidence of plane sections not remaining plane, possible different internal cracking mechanisms, amongst other local strain behavior differences, which could have implications for future modeling and design of lightly reinforced RC members with small diameter bars.
Experimental Study on Alfvén Instability in a Magneto‐Plasma Dynamic Arc‐Jet Collisional Finite‐β Plasma

Published: July 2024

AbstractTest plasma high‐density (TPH) was a research facility that started in the 1980s, generated high‐density plasma using magneto‐plasma‐dynamic (MPD) arc‐jet, , where is the ratio of the kinetic pressure divided by the magnetic field pressure. In this work, we aim to authenticate the method used in the identification of the current‐driven instability in high‐frequency mode as Alfvén instability, standing on the linear trend of the difference of the phase of the Fourier transforms of the magnetic field fluctuation. The dependence of the wavenumber‐versus‐frequency shows a linear regression, close to the Alfvén velocity expected from the plasma density, ion mass and the strength of the magnetic field. With short wave packets of the left‐hand, circularly polarized Alfvén waves were recorded for the spectral analysis and reconstructed the spatial changes in the phase spectrum. The dispersion in the frequency stretch was found to be traced as the Alfvén mode. Artifacts such as standing waves affect a narrow range of phase spectra and have large leverage as an error in the linear regression analysis. The coherence spectrum for the validation and the method of recovering data using maximum likelihood estimation will be presented. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

Authors: Kuzmina Liudmila I. , Osipov Yuri V. 
Published: July 2024

AbstractFiltration problems of suspensions and colloids in porous media are considered when designing tunnels and underground structures. To strengthen weak soil, a liquid solution is injected into the rock, the particles of which are filtered in the pores and distributed far from the well. A deep bed filtration model of 2-particle suspension in a porous material is considered. The purpose of the work is to determine the model parameters from the measured outlet concentration of suspended particles. Using an explicit solution to the direct filtration problem on the concentration front, the inverse problem is reduced to a system of nonlinear algebraic equations, which is a special case of the moment problem. The system is solved by passing to a canonical basis in the space of symmetric polynomials. Conditions for the existence of a solution are obtained. An explicit solution is constructed. The inverse filtration problem of a suspension with particles of two types is solved, determining the initial partial concentrations and filtration coefficients.
Review on Impacts of Geometric Imperfections on Behavior of Cold-Formed Structural Members
Authors: Vu Quoc Anh , Pham Ngoc Hieu 
Published: July 2024

AbstractCold-formed structural members have been demonstrated to be highly sensitive to buckling modes due to their small thickness. Cold-formed sections have been identified to exhibit significant geometric imperfections which have been illustrated to significantly affect the stability and should be considered in structural analyses of such cold-formed structural members. Their effects were presented in a variety of previous investigations, but these obtained results were still discrete without general evaluations. Therefore, this paper will provide an overview on the impacts of various imperfection components on the behavior of cold-formed structural members. Subsequently, several previous investigations on structural behaviors of cold-rolled structural members were summarized and thoroughly analyzed to enhance understanding of the influence of each geometric imperfection component. It was found that sectional imperfection components should be considered in the analyses for short and intermediate structural members whereas global imperfection components should be included in the analysis of long structural members. Also, bucking behaviors of a structural member were governed by combinations of various imperfection components instead of any single component. These findings will be the base for future investigations of such members under the effects of geometric imperfections.

Published: July 2024

AbstractAn improved precast bearing wall structure was proposed, with light weight gauge steel members embedded in the wall, forming full length hole for dowels passing through, which can provide higher speed and lower cost construction method, especially for low rise buildings. The shear and tensile behavior of the horizontal joints for the novel precast bearing wall structure were studied through experimental and numerical investigation in this paper. Three identical specimens for horizontal joints shear and tensile tests separately were tested. The shear test specimens were designed from the wall-slab-wall connection part while the tensile test specimens were designed from the wall-foundation connection part. The whole experimental process from crack generation to joints failure was investigated in detail and the load-displacement curves were provided and analysed. Based on experimental results, the finite element models of both type specimens are verified and calibrated using ABAQUS. The shear and tensile failure mechanism of horizontal joints is presented and the recommendations to increasing the horizontal joints strength capacity and ductile performance are proposed, which may provide practical guidance for future engineering practice.

Research on the Maturity of Intelligent Construction Management in the Whole Process of Prefabricated Buildings
Authors: Zhang Huili 
Published: July 2024

AbstractIntelligent construction is an important means of industrialization in new construction, which can realize the whole process of prefabricated buildings, all-round information, integration, digitalization and intelligent management, and reshape the value chain and supply chain system of the construction industry. At present, the relevant research on prefabricated intelligent construction is relatively fragmented and independent, and there are few studies on the intelligent construction management of the whole process of prefabricated buildings. So it is difficult for us to accurately estimate the level of intelligent manufacturing capabilities of contractors in prefabricated buildings. Starting from prefabricated buildings and intelligent construction under the background of new-type building industrialization, this paper constructs the maturity model, maturity evaluation index and evaluation standard of the intelligent construction management of the whole process of prefabricated buildings. It is expected to be helpful for the evaluation and improvement of the level of intelligent construction management in the entire process of prefabricated buildings.
