The micromachining of GaAs with three different truly three-dimensional (3D) molds were performed by the confined etchant layer technique (CELT). The etched patterns were found, approximately, to be the negative copy of the 3D molds. The general comparison of CELT with the existing micromachining techniques, such as two-dimensional (2D) projection lithography and electro-discharge machining, was made...
The present work used mainly electrochemical in situ time-resolved UV-vis subtractive reflectance spectroscopy to study the electron transfer process of cytochrome c in the presence of promoter (the equal molar mixture of guanine and cytosine). Two new absorption bands 450 and 500 nm and two bipolar bands 250 and 300 nm are observed in the spectra with different time resolutions. In addition, the...
