Breaking the Specific Capacity Limit: 409% Boost in Manganese-Based Redox Flow Batteries at High Current Densities with a MnO2 Semi-Solid Slurry Electrolyte

Xin Liu, Zhang Chen, Daiqi Zhou, Qi Zhao et autres

Abstract The common-ion effect of SO 4 2− limits the solubility of MnSO 4 to ≤ 1 M in conventional H 2 SO 4 electrolytes, resulting in low specific capacity of manganese (Mn)-based redox flow batteries (RFBs). Although MnO 2 semi-solid RFBs …

SparseLGS: Sparse View Language Embedded Gaussian Splatting

Jun Peng Hu, Zhang Chen, Zhong Li, Yi Xu et autres

Recently, several studies have combined Gaussian Splatting to obtain scene representations with language embeddings for open-vocabulary 3D scene understanding. While these methods perform well, they essentially require very dense multi-view inputs, limiting their applicability in real-world scenarios. In this work, we propose …

Comparison of Two Lifespan Prediction Models for Polyethylene Gas Pipes in Civil Engineering

W CHEN, Shunsong Guo, Li Xia, Zhang Chen et autres

Abstract Two life prediction models for polyethylene (PE) pipe were proposed based on long-term hydrostatic testing and physicochemical property analysis methods, respectively. The principles and prediction procedures of each model were elaborated in detail. A case study was conducted, where the two …

Asymmetric Response of Summer Extreme Heat Events to CO2 Removal Scenarios in Eastern Sichuan–Chongqing, China

Bingbing Jiang, Zhang Chen, Yiyun Fu, Zhibiao Wang

In recent decades, summer extreme high-temperature (EHT) events in the Sichuan–Chongqing (SC) region of southwestern China have become increasingly frequent under global warming. Carbon dioxide removal (CDR) is considered a key strategy for achieving the temperature targets of the Paris Agreement; however, …

Intensified Population Exposure Risks of Compound Heatwaves Over Sichuan–Chongqing: The Role of Anomalous Tibetan Plateau Heat Source

Huning Chen, Fei Ge, Zhang Chen, Quanliang Chen

ABSTRACT Compared with heatwaves that occur only at daytime or nighttime, daytime‐nighttime compound heatwaves (CHWs) cause more severe damage to natural ecosystems and human society. This study aims to investigate the relationship between the frequency of compound heatwaves (CHWF) in the Sichuan–Chongqing …

Tetrameric Electron Donor–Acceptor Complex-Mediated Cascade Cyclization for the Synthesis of Tetrahydropyridoindole

Xi Zhang, Zhang Chen, Dong-Xiao Jiang, Lixian shen et autres

Herein, we describe a photochemical strategy for synthesizing tetrahydropyridoindoles via a cascade decarboxylative cyclization between indolyl NHPI esters and alkenes. This protocol showcased a broad substrate scope, accommodating primary, secondary, and tertiary alkyl radicals generated from decarboxylation of NHPI esters. Diverse functional …
