PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

open access: yesPolymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...

Blade Crack Detection using Blade Tip Timing

IEEE Transactions on Instrumentation and Measurement, 2021
The harsh working environment of compressor threats the integrality of bladed disk. Crack is one of the most fatal faults of rotating blades. Detecting the crack of blades at early stage could ensure the safe operation of gas turbine and save economic costs.

An OPR-Free Blade Tip Timing Method for Rotating Blade Condition Monitoring

IEEE Transactions on Instrumentation and Measurement, 2021
Blade tip timing (BTT) is a noncontact blade vibration measurement method for rotating blade condition monitoring. However, it is difficult to install a once-per-revolution (OPR) probe due to the internal environment limitation of an engine. To solve this problem, an OPR-free BTT method is proposed in this article.

An OPR-free Blade Tip Timing Method Based on Blade Spacing Change

2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020
Compressor blades often operate in high temper-ature, high pressure, and heavy load environments. They are in direct contact with the outside air, which causes their life to be severely limited. Blade vibration is an important factor that reflecting the state of the blade. Therefore, effective blade vibration monitoring methods are needed.
