Electro‐Active Polymer Actuated Microfiltration Membranes: Design, Performance, and Particle Dynamics

Advanced Functional Materials, EarlyView.
The concept of foulant particle manipulation and detachment from active microfiltration membranes via voltage‐driven vibrations is introduced. Actuator components are initially integrated onto the filtration membranes using an airbrush spray printing technique.

An Investigation on the Effect of Endwall Movement on the Tip Clearance Loss Using Annular Turbine Cascade

International Journal of Rotating Machinery, 2011
The aerodynamic losses in gas turbines are mainly caused by profile loss secondary flow, and tip leakage loss. This study focuses on tip leakage flow of high-pressure turbine stages.

Dual‐Functional Li2B4O7 Coating on Carbon Fibers for Enhanced Li+ Transport and Stability in Sulfide All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
A dual‐functional Li2B4O7 coating on carbon fibers is designed to resolve the critical interfacial degradation in sulfide all‐solid‐state batteries. The conformal layer acts as a physical barrier to suppress parasitic reactions while its unique dielectric properties simultaneously facilitate Li+ transport.

Blood flow ratio in the gastric conduit measured by laser Doppler flowmetry: A predictor of anastomotic leakage after esophagectomy

Annals of Gastroenterological Surgery
Background Anastomotic leakage after esophagectomy is a common complication. Laser Doppler flowmetry (LDF) can quantitatively evaluate the blood flow in the gastric conduit.

Tip-Leakage Vortex Inception on a Ducted Rotor [PDF]

, 2001
The tip-leakage vortex occurring on a ducted rotor was examined using both three component Laser Doppler Velocimetry (LDV) and planar Particle Imaging Velocimetry (PIV). The vortex strength and core size were examined for different vortex cross sections

RNA‐Micelles as Self‐Assembling Structures for Efficient Co‐Delivery of Synergistic siRNA and Nucleoside Analogues to Treat CRC Lung Metastasis

Advanced Functional Materials, EarlyView.
Two kinds of self‐assembled RNA micelles were used to co‐deliver synergistic siRNA and nucleoside analogues for the treatment of colorectal cancer lung metastases. Near‐complete elimination of lung cancer metastases was confirmed in an orthotopic lung metastasis model constructed using human colorectal cancer lung metastases patient surgical samples to

Heat transfer in the tip region of a rotor blade simulator [PDF]

In gas turbines, the blades of axial turbine stages rotate in close proximity to a stationary peripheral wall. Differential expansion of the turbine wheel, blades, and the shroud causes variations in the size of the clearance gap between blade tip and ...
