Resolving the Sensitivity–Specificity Trade‐Off in Fluorescent Probes via a Tandem‐Activatable Shielding Strategy

ABSTRACT For precise tumor diagnosis, the intrinsic trade‐off between sensitivity and specificity in fluorescent probes remains a longstanding bottleneck, underscoring an urgent need for strategies to break this fundamental constraint. To address the specificity limitation, we ex...

Interpenetrating Elastomers for High-Fidelity Shape Recovery and Broad Temperature Energy Dissipation

The design of elastomers integrating high-fidelity shape memory behavior with broad-temperature energy dissipation remains a fundamental challenge due to the intrinsic trade-off between network rigidity and segmental mobility. Here, an interpenetrating polymer network (IPN) strat...

Multi-Objective and Dynamic Optimization on Fast Charging Strategies for Lithium-Ion Batteries Based on MCC-CV

The widespread deployment of lithium-ion batteries (LIBs) in electric vehicles and energy storage systems urgently requires advanced fast-charging strategies that simultaneously improve charging efficiency and cycle durability. Traditional multi-stage constant-current constant-vo...

MACF1 condensates serve as molecular rheostats translating mechanical stress into bone adaptation

Bone dynamically maintains homeostasis through mechanotransduction, a process essential for skeletal integrity and frequently disrupted in disease. Yet how bone cells decode mechanical cues into adaptive responses remains poorly understood. Here, we identify MACF1, a cytoskeletal...

Realization of Reversible Regulation of Thermal Conductivity in 2D Materials through Engineered Acoustic Mismatch

Forward self-similar solutions to the MHD-Boussinesq system with Newtonian gravitational field

This paper is concerned with the existence of forward self-similar solutions to the three-dimensional Magnetohydrodynamic-Boussinesq (MHD-Boussinesq) system with a Newtonian gravitational field. By employing a blow-up argument and the Leray-Schauder theorem, we construct a forwar...

A single-ended fault location method based on active boundary control for multi-terminal flexible DC grids

In modular multilevel converter (MMC)-based multi-terminal flexible DC (MTDC) grids, fault current limiting suppresses post-fault electrical transients and weakens available fault characteristics, thereby reducing the sensitivity and reliability of conventional fault location met...

The Shear-Bond Descriptor and Universal Machine-Learning Potential Enable Large-Scale Discovery of Negative Thermal Expansion Materials

Abstract Negative thermal expansion (NTE) materials are crucial for mitigating thermal stresses and designing dimensionally stable components in advanced technologies, yet compounds exhibiting this anomalous behavior remain intrinsically rare. The discovery of novel NTE crystals...

Vane detachment in rotary compressors under low-speed conditions: Mechanisms based on mixed lubrication analysis

To ensure comfort and save energy, room air conditioners need to operate under low-temperature cooling and high-temperature heating conditions, under which the rotary compressor often runs at low rotational speeds (below approximately 20 Hz for cooling and 30 Hz for heating). Thi...
