Nanocrystalline PbI₂coated on a cellulose fiber frame for paper-based flexible X-ray detection

Abstract

In this work, paper-based flexible X-ray detectors were developed. An outstanding detection performance and high stability were realized by combining the intrinsic flexibility of PbI2 nanocrystal, and the bendability of...

Vertical Van Der Waals Epitaxy of p‐MoxRe1‐Xs2 on GaN for Ultrahigh Detectivity Uv–vis–NIR Photodetector

“…[ 68 ] To provide further explanation on this phenomenon, we conducted calculations to determine the density of states (DOS) of pure ReS 2 and p‐Mo x Re 1‐ x S 2 , along with the projected density of states (PDOS) associated with the Mo‐d orbitals, drawing inspiration from previously published research. [ 69,70 ] These results are illustrated in Figure 4g. The incorporation of Mo atoms introduces a slight deviation in the conduction band minimum (CBM) and VBM of 1T' Mo x Re 1‐ x S 2 compared to pure ReS 2 .…”

Nanowires Framework Supported Porous Lotus‐Carbon Anode Boosts Lithium‐Ion and Sodium‐Ion Batteries

“…Figure 4c displays the cycle performances of the LPC anodes in LIB and SIB at 0.2 C. The reversible capacity can reach 738 mA h g −1 and 460 ma h g −1 after 300 cycles in LIB and SIB, respectively, the capacity attenuation of LIB during the first few cycles is attributed to the formation of SEI layers that take electrolyte as consumption. [ 16 ] Noted that when performed at high current densities (i.e., 2 C in Figure 4d and 5 C in Figure 4e), after the formation of SEI, the LIBs exhibit an increased reversible capacity from 350 mA h g −1 to 570 mA h g −1 at 2 C and 285 mA h g −1 to 440 mA h g −1 at 5 C after 1000 cycles, respectively, which is attributed to the fast structure activation of electrode as well as the full infiltration of electrolyte. [ 53 ] Although the SIBs only maintain the reversible capacity of 283 and 219 mA h g −1 at the same condition, the value is significantly higher than the as‐reported bio‐carbon and even hard‐carbon, for the SIBs anodes always suffer from a severe capacity decay at large current densities, which derived from the severe structural collapse caused by large‐sized Na + , and a substantial electrolyte consumption will happen in long‐term cycling processes.…”

“…[ 15 ] As a result, porous carbon (PC) anodes with tunable microstructure, diverse forms, and large specific surface areas, have garnered significant attention for their potential application in both LIBs and SIBs. [ 16–18 ] Natural biomass is the most common carbon source for preparing PC, disordered, or hard carbon anodes, such as switchgrass, [ 19 ] peels, [ 20 ] etc. And diverse microstructure and morphology of carbon nanomaterials can be obtained by intentionally selecting biomass precursors with intrinsic structure.…”

Stroke Risk Prediction from Medical Survey Data: AI-Driven Risk Analysis with Insightful Feature Importance using Explainable AI (XAI)

“…The SHapley Additive exPlanations (SHAP) [22] [23] approach is used in this section to uncover the inherent relevance of various characteristics within the selected dataset represented in Fig 3 . The SHAP summary plot is used to visualize the significance by focusing exclusively on the top Fig. 2: Representation of the complete workflow to address stroke risk prediction from medical survey data.…”
