“…As a result, the accurate measurement reached a mean grain height of 11 nm. Kaplan (2021) [10] researched the Si photodiode and material characterization of TiO 2 and proposed a different technique to measure the height with an AFM. The result was 3 nm high, and the accuracy was significant.…”

This paper describes the non-contact optical detection of debris material that adheres to the substrates of color filters (CFs) and thin-film transistors (TFTs) by area charge-coupled devices (CCDs) and laser sensors. One of the optical detections is a side-view illumination by an area CCD that emits a coherency light to detect debris on the CF. In contrast to the height of the debris material, the image is acquired by transforming the geometric shape from a square to a circle. As a result, the side-view illumination from the area CCD identified the height of the debris adhered to the black matrix (BM) as well as the red, green, and blue of a CF with 95, 97, 98, and 99% accuracy compared to the golden sample. The uncertainty analysis was at 5% for the BM, 3% for the red, 2% for the green, and 1% for the blue. The other optical detection, a laser optical interception with a horizontal alignment, inspected the material foreign to the TFT. At the same time, laser sensors intercepted the debris on the TFT at a voltage of 3.5 V, which the five sets of laser optics make scanning the sample. Consequently, the scanning rate reached over 98% accuracy, and the uncertainty analysis was within 5%. Thus, both non-contact optical methods can detect debris at a 50 μm height or lower. The experiment presents a successful design for the efficient prevention of a valuable component malfunction.

“…TVA system is plasma assistant coating technology working in high vacuum conditions. TVA is not used to deposit many materials [27][28][29][30][31] but also coats the two dimensional nano materials such as BN, graphene and MXene materials. 22,32,33 2D nano materials exhibit improved properties in special applications.…”

Boron nitride (BN) nano coating was deposited on 304 type stainless steel sheets by standard thermionic vacuum arc (TVA) as a physical vapour deposition ) method. Deposited BN nano coating was characterized by attenuated total reflectance Fourier transform infrared spectroscopy, Raman spectroscopy, field emission scanning electron microscopy and X-ray diffraction analyses tools. Corrosion performances of un-coated and BN nano material coated steel samples were investigated in 1 M H2SO4 solution using Eocp-time curves, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. BN nano coating was found to provide anodic protection to the steel and reduced significantly corrosion rate of 304 steel in acidic medium. Long-term corrosion tests results demonstrated that the BN nano coating has ability to protect the 304 stainless steel in sulfuric acid corrosive media during 10 days and the protective behavior of the BN nano coating results from passivation effect of the coating against the attack of corrosive environment. Finally, BN nano coating is a promising two-dimensional coating material for corrosion protection of stainless steel.
