Effects of CeO2on Microstructural Evolution, Corrosion and Tribology Behavior of Laser Cladded TiC Reinforced Co-based Coatings

International Journal of Electrochemical Science, 2021
TiC/Co-based composite coatings with different CeO2 contents were successfully fabricated on 9Cr ferritic steel by laser cladding. The effects of CeO2 on microstructure, corrosion and wear resistance of laser cladded TiC/Co-based composite coatings were ...

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

Advanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

Inspection of Underwater Hull Surface Condition Using the Soft Voting Ensemble of the Transfer-Learned Models

Italian National Conference on Sensors, 2022
In this study, we propose a method for inspecting the condition of hull surfaces using underwater images acquired from the camera of a remotely controlled underwater vehicle (ROUV). To this end, a soft voting ensemble classifier comprising six well-known

Molecular Inks for the Development of Complex 3D In‐Mold Electronics

Advanced Materials Technologies, EarlyView.
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...

Autonomous Inspection Strategies and Simulation for Large Aquaculture Net Cages Based on Deep Visual Perception

Journal of Marine Science and Engineering
In China, a single large deep-sea net cage can raise nearly one million fish. If the fish net is damaged and the fish escape, it can lead to significant economic losses and ecological damage.
