A new soft sensing method based on serial-parallel GRU with self-attention mechanism for complex multi-unit industrial processes.

With the deep digital transformation of traditional manufacturing industry and the continuous automation level improvement of production lines, it is more important to predict the Key Performance Indicators (KPIs) of processes in a timely and accurate manner. The traditional laboratory destructive test method for obtaining KPIs consumes a large amount of time and incurs high costs, which not only fails to provide timely and effective guidance for production processes but also results in significant losses for manufacturing enterprises. To address these issues, an online prediction soft sensor model for KPIs based on a serial-parallel gated recurrent unit with self-attention mechanism (SPGRU-SA) soft sensor model is proposed.

Dual-Functional Microneedles for In Situ Diagnosis and Biofilm-Targeted Therapy of Diabetic Periodontitis via Biomarker-Responsive Probes and Photothermal NO Nanomotors.

Chronic periodontitis, a frequent complication of diabetes, is exacerbated by bacterial biofilms that drive progressive periodontal tissue destruction and systemic inflammation. Conventional treatments, utilizing mechanical debridement and systemic antibiotics, often fail to eradicate bacterial biofilms, promote antibiotic resistance, and lack real-time monitoring, leading to suboptimal therapeutic outcomes. Herein, we report a separable bilayer microneedle (MN) patch that enables localized, antibiotic-free, biofilm-targeted therapy and in situ biomarker-based monitoring for the integrated management of chronic periodontitis.

Tribo-Induced Interfacial Lubrication Performance and Self-Repair Mechanism of Oleylamine-Grafted Chlorinated Graphene.

Understanding the mechanism of action of graphene oxide (GO)-based lubrication materials is of great significance to effectively suppress the surface damage accumulation of bearing steel during service.

Real-space visualization of order-disorder transition in BaTiO.

Ferroelectricity in BaTiO was observed nearly 80 years ago, but the mechanism underlying its ferroelectric-paraelectric phase transition remains elusive. The order-disorder transition has been recognized as playing a critical role; however, the precise nature of the order parameter still remains under scrutiny, including the local dipole direction and the correlations above and below the Curie temperature. Using in situ scanning transmission electron microscopy, we directly map polar displacements in BaTiO across the ferroelectric-paraelectric phase transition, providing atomistic insights into an order-disorder mechanism.
