Recrystallization Behavior of MgAl Layered Double Hydroxide Films on Anodized Magnesium Alloys During Phytic Acid Loading

MgAl layered double hydroxides (LDHs) films were prepared via an in-situ growth method on anodized AZ31 magnesium alloy. Subsequently, phytic acid (PA) was loaded as a corrosion inhibitor through an anion-exchange process. The structural evolution of the LDHs nanosheets during th...

DMC-YOLO: An improved YOLOv12-based approach for ship detection in distributed acoustic sensing images

Ship detection plays a vital role in ensuring maritime transportation and navigation safety. However, achieving accurate and efficient detection in distributed acoustic sensing (DAS) images remains challenging due to unique linear texture features, complex hydroacoustic backgroun...

Optimal estimates of the first gap for periodic Sturm-Liouville problems with indefinite weights

The present paper studies the first gap of periodic Sturm-Liouville problems with indefinite weights which arise from Camassa-Holm equations. The optimal infimum of the first gap is obtained and the optimal indefinite weight is investigated. The main results are based on the trac...

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

ABSTRACT Achieving on‐demand glucose control to prevent postprandial spikes remains a significant challenge in diabetes management. Here, we present a programmable self‐heating microneedle (PSH‐MN) patch for on‐demand, timed‑sequence insulin delivery. The patch features a three‐d...

Temporal-semantic alignment and adaptive calibration network for industrial zero-shot fault diagnosis

Fault diagnosis is critical for mitigating potential risks and ensuring the operational safety of dynamic industrial systems. Zero-shot learning (ZSL) provides a promising solution for diagnosing unseen faults without labeled training samples. However, its application to industri...

A Tailored PbS/PbSe Double Hole Transport Layer for High-Performance Full-Inorganic Sb2S3 Indoor Photovoltaics

Abstract The severe nonradiative recombination at the back-contact (BC) interface significantly hinders the enhancement of device performance in antimony sulfide (Sb2S3) solar cells. One of the attributable issues is the insufficient coverage rate of a single-layer hole transport...
