Defect detection

Pulsed Eddy Current (PEC) testing is a non-destructive testing (NDT) technique that has been widely used in various applications, including the detection and characterization of defects in metallic materials. The measurement of pulsed eddy current signals is essential for this purpose. This study proposes a novel multi-sensor PEC approach for improved defect detection.

The study will focus on monitoring defects and finding out the nature of these defects. Bulk GaN was irradiated by a 2 MeV electron beam at a fluence of 5×1016 cm2 and studied by deep-level transient spectroscopy (DLTS). After irradiation, a broad peak, including at least two traps, was detected. The trap D1 (EC −0.16 eV) observed from a broad peak is induced during the annealing process below 550K and completely annealed out at 550K after 10 hours.

The physiological role of sulfoquinovosyl diacylglycerol (SQDG) in photosynthesis was investigated with a SQDG defective mutant (hf-2) of Chlamydomonas reinhardtii that did not have any detectable amount of SQDG. The mutant showed a lower rate of photosystem II (PSII) activity by  40% and also a lower growth rate than those of the wildtype. Results of genetical analysis of hf-2 strongly suggest that the SQDG defect and the lowered PSII activity are due to a single gene mutation.
