Purpose:In patients with heatstroke, disseminated intravascular coagulation (DIC) is associated with greater risk of in-hospital mortality. However, time-consuming assays or a complex diagnostic system may delay immediate treatment. Therefore, the present study proposes a new heatstroke-induced coagulopathy (HIC) score in patients with heat illness as an early warning indicator for ***:This retrospective study enrolled patients with heat illness in 24 Chinese hospitals from March 2021 to May 2022. Patients under 18 years old, with a congenital clotting disorder or liver disease, or using anticoagulants were excluded. Data were collected on demographic characteristics, routine blood tests, conventional coagulation assays and biochemical indexes. The risk factors related to coagulation function in heatstroke were identified by regression analysis, and used to construct a scoring system for HIC. The data of patients who met the diagnostic criteria for HIC and International Society on Thrombosis and Haemostasis defined-DIC were analyzed. All statistical analyses were performed using SPSS ***:The final analysis included 302 patients with heat illness, of whom 131 (43.4%) suffered from heatstroke, including 7 death (5.3%). Core temperature (OR = 1.681, 95% CI 1.291 - 2.189, p < 0.001), prothrombin time (OR = 1.427, 95% CI 1.175 - 1.733, p < 0.001) and D-dimer (OR = 1.242, 95% CI 1.049 - 1.471, p = 0.012) were independent risk factors for heatstroke, and therefore used to construct an HIC scoring system because of their close relation with abnormal coagulation. A total score ≥ 3 indicated HIC, and HIC scores correlated with the score for International Society of Thrombosis and Hemostasis-DIC (r = 0.8848, p < 0.001). The incidence of HIC (27.5%) was higher than that of DIC (11.2%) in all of 131 heatstroke patients. Meanwhile, the mortality rate of HIC (19.4%) was lower than that of DIC (46.7%). When HIC developed into DIC, parameters of coagulation dysfunct

Continuous Fe3+releasing enabled complete reconstruction of Ni-based MOF for promoted water oxidation in industrial alkali

引用

Science China Chemistry 2024年第9期67卷 2949-2957页

作者： Zhaojian Wang wei zhang Wenzhong Huang Ruohan Yu Changliang Chen Liqiang Mai Liang Zhou State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Sanya Science and Education Innovation Park Wuhan University of Technology Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)

Most oxygen evolution reaction（OER） electrocatalysts show poor stability under industrial alkaline conditions（20–30 wt.%KOH）. Therefore, it is essential to develop stable, efficient, and low-cost OER catalysts for industrial water electrolysis. Herein,we present a straightforward approach for the complete electrochemical reconstruction of Ni-BDC, a Ni-based metal-organic framework, for OER. This method involves the continuous release of Fe3+from Fe foam counter electrode in a high-concentration（6.0 M, 25 wt.%） KOH solution. The continuously Fe3+releasing not only realizes in situ Fe3+doping, but also introduces abundant defects in the obtained catalyst during cyclic voltammetry activation, thereby accelerating the electrochemical reconstruction. The reconstructed OER catalyst(Fe-doped nickel hydroxide/oxyhydroxide nanosheets supported on Ni foam, Fe-Ni Ox（OH）y/NF) manifests a low overpotential of 217 mV at 10 mA cm-2and 263 m V at 100 m A cm-2in 1.0 M ***, the Fe-NiOx（OH）y/NF also demonstrates high stability in 30 wt.% KOH. This strategy of regulating the electrochemical reconstruction process sheds light on the construction of stable and efficient OER catalysts for industrial water electrolysis.

Density-Functional Theories for Polyelectrolyte Systems

Chinese Journal of Polymer Science 2024年第09期 1302-1312页

作者： Jia-wei zhang Yu-Hang zhang Bao-Hui Li Qiang Wang School of Physics Nankai University Department of Chemical and Biological Engineering Colorado State University

Polymer density-functional theories (PDFTs) have distinct advantages in the study of polyelectrolyte (PE) systems over experiments and molecular simulations. Here we give an introductory review of some PDFTs recently developed for PE systems. We start with a general formalism of PDFTs and its relation to the widely used polymer self-consistent field theory (SCFT), then explain the various correlations that are neglected in SCFT but can be accounted for in PDFTs, including those due to the excluded-volume interaction and chain connectivity of uncharged polymers, the electrostatic correlations of small ions, and the chain correlations in PEs. We also list some applications of PDFTs for PE systems, and finally give some perspectives on future work. We hope that our review can attract more researchers to apply and further develop PDFTs as a promising class of theoretical and computational tools.

Photoelectric synaptic devices could emulate synaptic behaviors utilizing photoelectric effects and offer promising prospects with their high-speed operation and low crosstalk. In this study, we introduced a novel InGaZnO-based photoelectric memristor. Under both electrical and optical stimulation, the device successfully emulated synaptic characteristics including excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), long-term potentiation (LTP), and long-term depression (LTD). Furthermore, we demonstrated the practical application of our synaptic devices through the recognition of handwritten digits. The devices have successfully shown their ability to modulate synaptic weights effectively through light pulse stimulation, resulting in a recognition accuracy of up to 93.4%. The results illustrated the potential of IGZO-based memristors in neuromorphic computing, particularly their ability to simulate synaptic functionalities and contribute to image recognition tasks.
