Ultrasonic probes without delay line, in order to improve SNR thermal shock resistance were developed. New immersion probe was composed by PZT/PZT sol-gel composite film onto thin metal plate with protection case. High temperature durability was achieved because sol-gel composite film had good acoustic coupling without couplant, had reasonable broadband characteristic without backing material, and...
A new indoline dye in which a double rhodanine acceptor is attached to the indoline moiety by a p-phenylene spacer on the indoline–nitrogen, has been examined for its performance as a sensitizer for zinc oxide dye-sensitized solar cells. In the presence of cholic acid, chenodeoxycholic acid, or lithocholic acid; the performance was greatest for lithocholic acid as this showed the greatest reduction...
New sol-gel composite made by CaBi4Ti4O15 (CBT) piezoelectric powder and lead zirconate titanate (PZT) sol-gel was investigated for high temperature ultrasonic transducer applications. CBT was chosen because of relatively high Curie temperature, ∼790°C. PZT sol-gel was chosen because of high dielectric constant. In order to investigate high temperature performance of CBT/PZT, CBT/PZT films were fabricated...
