Liquid Film Thickness Estimation using Electrical Capacitance Tomography

Measurement Science Review, 2014
In air/oil lubrication systems, the flow parameters, e.g., flow pattern, liquid film thickness, and air/oil flow rate, are of great importance to the transportation efficiency.

Numerical investigation of a novel device for bubble generation to reduce ship drag

International Journal of Naval Architecture and Ocean Engineering, 2018
For a sailing ship, the frictional resistance exerted on the hull of ship is due to viscous effect of the fluid flow, which is proportional to the wetted area of the hull and moving speed of ship.

The Tribological Performance of Frictional Pair of Gas–Liquid Miscible Backflow Pumping Seal in Oil–Air Environment

Lubricants, 2023
The gas–liquid miscible backflow pumping seal (G-LMBPHS) is a non-contact mechanical seal that is suitable for high-speed bearing chambers. However, the tribological properties and wear mechanisms of the frictional pair of G-LMBPHS in an oil–air ...

Binder‐Free Direct Ink Writing of Li6.4La3Zr1.4Ta0.6O12 Garnet Electrolytes for All‐Solid‐State Batteries

Advanced Materials Interfaces, EarlyView.
Polymer binders and thick pressed LLZTO pellets limit all‐solid‐state battery integration through grain‐boundary carbon and high ohmic losses. A binder‐free capillary suspension ink is direct‐ink‐written and sintered into 254 μm$\mu{\rm m}$, 95.8%‐dense Ta‐stabilized LLZTO with 17.3 mS cm−1$\text{cm}^{-1}$ bulk conductivity, enabling thinner ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

Advanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

Development of Air lubrication system and verification by the full scale ship test

Journal of the Japan Society of Naval Architects and Ocean Engineers, 2010
In late years, a demand for the carbon dioxide discharge reduction from a ship and the reduction of the operation cost has been risen more and more. According to these backgrounds, the authors are grappling with establishment of the frictional resistance reduction technology of the ship by means of the air lubrication methods.

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

Advanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in
