Many-body interactions between quasiparticles (electrons, excitons, and phonons) have led to the emergence of new complex correlated states and are at the core of condensed matter physics and material science. In low-dimensional materials, unique electronic properties for these correlated states could significantly affect their optical properties. Herein, combining photoluminescence, optical reflection measurements and theoretical calculations, we demonstrate an unconventional excitonic state and its bound phonon sideband in layered silicon diphosphide (SiP2), in which the bound electron-hole pair is composed of electrons confined within one-dimensional phosphorus–phosphorus chains and holes extended in two-dimensional SiP2 layers. The excitonic state and the emergent phonon sideband show linear dichroism and large energy redshifts with increasing temperature. Within the GW plus Bethe–Salpeter equation calculations and solving the generalized Holstein model non-perturbatively, we confirm that the observed sideband feature results from the correlated interaction between excitons and optical phonons. Such a layered material provides a new platform to study excitonic physics and many-particle effects. Copyright © 2022, The Authors. All rights reserved.

There is a significant comorbidity between cardiovascular diseases (CVD) and depression that is highly predictive of poor clinical outcome. Yet, its underlying biological pathways remain challenging to decipher, presumably due to its non-linear associations across multiple mechanisms. Mutual information provides a framework to analyze such intricacies. In this study, we proposed a multipartite projection method based on mutual information correlations to construct multilayer disease networks. We applied the method to a cross-sectional dataset from a wave of the Young Finns Study. This dataset assesses CVD and depression, along with related risk factors and two omics of biomarkers: metabolites and lipids. Instead of directly correlating CVD-related phenotypes and depressive symptoms, we extended the notion of bipartite networks to create a multipartite network that connects these phenotype and symptom variables to intermediate biological variables. Projecting from these intermediate variables results in a weighted multilayer network, where each link between CVD and depression variables is marked by its 'layer' (i.e., metabolome or lipidome). Using this projection method, we identified potential mediating biomarkers that connect CVD to depression. These included metabolites such as creatinine, valine, phospholipids in very large high-density lipoproteins HDL, triglycerides in small low-density lipoproteins (LDL), and apolipoprotein B;and lipids such as specific sphingomyelins (SM), phosphatidylcholines (PC), triacylglycerols (TAG) and diacylglycerols (DAG). These biomarkers thus may play significant roles in the biological pathways of CVD-depression comorbidity. Additionally, the projected network highlights sex and BMI as the most important risk factors, or confounders, associated with the comorbidity. Our method can generalize to any number of omics layers and disease phenotypes, offering a truly system-level overview of biological pathways contributing to comorbidi

IOP Conference Series: Earth and Environmental science 2022年第1期983卷

In the study of wind engineering problems, it is of considerable importance to obtain accurate surface wind field characteristics. Surface features have significant impacts on the characteristics of small- and micro-scale wind field, so the fine reconstruction of terrain features is the basis of small- and micro-scale wind field simulations. However, since the GIS data obtained by satellite scanning cannot be directly used for CFD numerical simulation, the geographic information data is usually of considerable amount and contains a large number of waste points, thus difficult to be completed by manual modeling. To solve this problem, an automatic waste point repair algorithm and a grid aggregation method based on greedy algorithm are proposed, which can quickly and efficiently reconstruct the surface and generate the grid. Relying on the national numerical wind tunnel project and integrating the above core algorithms with the pre-processing and post-processing modules, a general and efficient surface mesh generation software ESM (Earth Surface Mesh) has been developed. Compared with the surface modeling and grid generation modules provided by other software, ESM has more comprehensive functions, and surface grid rapid generation technologies such as waste point data processing, grid adaptive refinement based on elevation change, high fidelity interpolation technology and partition splicing generation. It supports more interfaces and can generate structured and unstructured grids. The preliminary example shows that the surface grid generated by ESM meets the needs of wind engineering simulation.

Metallic bone screws are clinically used to fix the fractured bone fragments in bone defect treatment;yet they present compromised therapeutic efficacy due to poor osseointegration and tissue support. Here, we develop a novel programmable shape memory polymers (SMP) bone screw with osteogenesis-angiogenesis coupling for enhanced bone regeneration. The SMP bone screw could shrink and be easily reshaped at room temperature (25°C) and then rapidly recover to its original state (37°C), granting it robust internal fixation capacity (2-fold increase in pull-out force) and beneficial compressive force to nearby tissues. Additionally, the long-term release of L-arginine and calcium ion synergistically activated the nitric oxide-cyclic guanosine monophosphate (NO-cGMP) signaling pathway of native cells. Synergized with its shape memory function, the SMP bone screw activated calcium signaling pathway under the stimulation of mechanical stress, promoted the activation of various osteogenic pathways (e.g. PI3K-Akt signaling pathway), and upregulated the NO-cGMP pathway by regulating the influx of calcium ions and arginine to synchronously coordinate osteogenesis and angiogenesis to accelerate bone repair. We envision that our programmable shape memory bone screw, with its easily reshaped and fast stress release properties promoting osteogenesis-angiogenesis coupling, can shed new light on the development of clinical bone screws. © 2024, The Authors.

The importance of nanocomposites with tailored properties is growing due to their applications in various fields. In the present study, poly(3,4-ethylenedioxythiophene) (PEDOT) and functionalized carbon nanoparticles (f-CNPs) are synthesized by in-situ chemical oxidative polymerization and pyrolysis methods, respectively. The f-CNPs-PEDOT nanocomposites are prepared by varying the concentration of PEDOT (i.e., 1, 2.5, 5, 10, and 20 wt%), and the thermal stability, dielectric properties and antibacterial activities of f-CNPs-PEDOT nanocomposites were evaluated. The dielectric studies indicated that the addition of PEDOT has enhanced the dielectric properties due to interfacial polarization effect, whereas decreased the thermal stability due to degradation of PEDOT in the nanocomposite, however, it is higher than the pure PEDOT. The antimicrobial potential of synthesized f-CNPs-PEDOT nanocomposites was studied against two different bacterial strains, namely Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. The findings of this research have potential to open new opportunities for employing f-CNPs-PEDOT nanocomposites in physical sciences and antimicrobial applications. © 2024 The Authors

Achieving a net-zero target via a circular economy approach necessitates maximizing the recycling of waste into higher-value materials. In the present study, spent coffee grounds (SCG) from industrial food processing waste are converted into a high-performance anode material used in lithium-ion batteries via one-step carbonization of ZnCl2 at 550°C. The hybrid composites (HCs) are collected after the process contained C- and Zn-based mixed oxides, such as Zn2SiO4 and ZnFe2O4. The content of Zn-based mixed oxides in HCs increases with the initial ZnCl2:SCG mass ratio and reaches its maximum at a ratio of 2:1 wt/wt (HCs_2). The electrochemical performance of the HC-based anodes is proportional to the loaded Zn content when the ZnCl2:SCG mass ratio increases from 0 to 2. The optimized anode (HCs_2) exhibits a charge capacity of 692 mAh g-1 and capacity retention of 86% at the 100th cycle, whereas the corresponding values for HCs_0 anode (without ZnCl2 treatment) are 311 mAh g-1 and 73.3%. The superior electrochemical performance of the optimized anode is attributed to the nanosized Zn2SiO4 and ZnFe2O4, stabilization effect of carbon matrices, and a strategy that increases the proportions of high-capacity components. © 2023, The Authors.
