Decoupled Synthesis Pathway via Precursor Functionalization Stabilizes High‐Voltage Nickel‐Based Cathodes

ABSTRACT Nickel‐based layered cathodes are promising candidates for high‐performance, high‐energy lithium‐ion batteries, yet their high‐voltage application is jointly limited by synthesis‐inherited structural defects and an unstable lattice oxygen framework. Here, we show that bo...

Catalytic Enantioselective Addition of Aryl, Heteroaryl, and Alkenyl Halides to Aliphatic Aldehydes

ABSTRACT Cobalt complexes of chiral Josiphos catalyzed enantioselective addition of aryl, heteroaryl, and alkenyl halides to a wide range of linear and branched aliphatic aldehydes, without using directing groups. The new method was easily scalable with low loadings of cobalt cat...

Cooperative Computation for Multiuser Task Offloading in Wireless-Powered MEC Systems

This paper investigates joint computing and relaying for multiuser task offloading in a wireless-powered mobile edge computing (MEC) system comprising an energy node (EN), an edge server (ES), and multiple energy-harvesting users. One user is selected as the helper for the remain...

Nanofibrous aerogels with continuous conductivity gradient for ultrabroadband absorption-dominant electromagnetic interference shielding

Electromagnetic interference (EMI) shields are limited by a severe impedance mismatch with free space, leading to strong reflections and secondary radiation. Here, we introduce ultralight all-polymer aerogels featuring a continuous through-thickness conductivity gradient (MCAs),...

Intelligent prediction of diesel engine dynamic performance and emissions via multi-signal fusion and Bayesian optimization

An intelligent prediction framework integrating multi-signal feature learning and Bayesian optimization is proposed to address the strong nonlinearity, multivariable coupling, and dynamic evolution of diesel engine performance and emissions under transient operating conditions. A...

Nanobubbles (NBs) are unique gas-filled colloidal systems with significant potential for environmental remediation and sustainable resource management applications. Unlike conventional aeration or solid nanomaterials, NBs provide a high interfacial area, extended residence time,...

Cross-Condition State-of-Health Estimation of Lithium-Ion Batteries via Degradation-Feature Constraints and Domain-Difference Gating

To address the limited generalization of lithium-ion battery state-of-health (SOH) estimation under unseen aging conditions, this study proposes a degradation-feature-constrained domain-difference gated method (DFC-DGGate). Cycle-level features are constructed from capacity, volt...

MitoGPS: A Mitochondrial DNA G‐Quadruplex‐Targeting Strategy for Tumor‐Preferential Type I Photodynamic Therapy

ABSTRACT Photodynamic therapy (PDT) is a clinically promising, minimally invasive cancer treatment offering precise spatiotemporal control. However, achieving preferential tumor accumulation remains a critical challenge, which limits therapeutic efficacy and induces off‐target to...

Synergistic Molecular Modulation via Coordination and Hydrogen Bonding for Efficient Perovskite and Tandem Solar Cells

ABSTRACT Molecular additives offer a powerful route to control crystallization kinetics and homogenize component distribution in perovskite semiconductors. However, additives that integrate Pb‐related coordination and hydrogen‐bonding functionalities within a single molecular fra...

A Heating-AssistedIntegrated Purification-Enrichment-DerivatizationPaper Chip for Rapid MS/MS Quantification of Serum Steroid Hormones

Abstract Rapid and reliable simultaneous quantification of multiple steroid hormones is important for the diagnosis and monitoring of endocrine disorders such as polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS). Existing methods...

Generation and Dynamics of Reconfigurable Kerr Combs via Multimode Self‐Injection Locking

ABSTRACT Microresonator‐based Kerr combs provide a promising bridge directly linking the microwave and the optical frequency domain, bringing revolutions in optical metrology, spectroscopy, and frequency synthesis. Although self‐injection locking (SIL) has emerged as a powerful t...

Room‐Temperature Rapid Synthesis of Crystalline Ag─C Coordinated MOFs for Highly Efficient Acidic CO 2 Electroreduction

ABSTRACT The acidic CO 2 electroreduction reaction (eCO 2 RR) shows great promise in addressing carbonation issues encountered under neutral/alkaline conditions. However, it remains challenged by low selectivity arising from high proton availability, as well as catalyst degradati...
