Fundamental Studies of Halogen Reactions with Iii-v Semiconductor Surfaces

It is technologically important to understand how halogens react with semiconductor surfaces because halogen compounds are commonly used to etch semiconductor wafers in the microelectronics industry. Halogens are also model adsorbates for studying chemisorption on covalently bonded materials, such as semiconductors, owing to the simple nature of the bonds that they form. The growing use of III-...

Calibration Method Study of Ultrasonic Thickness Gauge

Since the invention of ultrasonic examination technology, the ultrasonic thickness gauge has been widely used and playing an important role in many field, such as service inspection of pipeline and pressure vessel, in the quality control of massive construction project, the dimension measurement of complicated-shaped mechanical components and so on. With the rapid growing of our country economy...

Histopathological Studies on Radiation Pneumonitis.

Studies on radiation pneumonitis have been made from the beginning of the 20th century in Europe and America. Prior to the Second World War, many articles have appeared including the works of Engelstad5> and Warren et al.25) who described the general aspects of this problem. In Japan, the incidence of this disease has been rare. A case report by Hamaguchi and Akazaki9) was only available before...
