Effect of substrate temperature on the crystalline of MgO thin films by RF magnetron sputtering--Research works accomplished by using materials a nalysis facilities: XXIX(2)--
Get PDFapplication/pdfMagnesium oxide (MgO) thin films are great concern as electrode protection layer with very high secondary emission coefficient (γ) in the application such as plasma display panel (PDP). We have studied the effect of the substrate temperature on the crystalline structure and the secondary emission coefficient γ of MgO films. The MgO thin films have been fabricated by RF magnetron sputtering technique with various substrate temperatures of growth parameters. The secondary emission coefficient γ were estimated the breakdown voltage in Ne gas. The crystalline structure of the films was confirmed by X-ray diffraction (XRD) analysis. As a result, the preferred orientation of MgO thin films was observed in the [200] plane at substrate temperature between room temperature and 700℃. For temperatures above 500 ℃, [111] plane peak was observed. The secondary emission coefficient γ had a maximum at the substrate temperature of about 500℃.departmental bulletin pape
Design of GroEL mutants with various reaction cycle time-- Research works accomplished by using materials analysis facilities:XXIX(3)--
Get PDFapplication/pdfThe chaperonin GroEL is an essential multisubunit assemblies that promotes facilitated protein folding in concert with ATP hydrolysis. The Escherichia coli GroEL consists of 14 identical subunits arranged in two heptamer rings. Each ring contains a central cavity and the two rings are stacked back-to-back. GroEL and its cofactor, GroES, form a nano-cage for a single molecule of substrate to fold, and undergo an ATPregulated interaction cycle to close and open the folding cage. Asp52 and Asp398 in GroEL are known as the critical residues on ATP hydrolysis because GroEL(D52A/D398A) mutant is severely deficient in ATP hydrolysis but not in ATP binding. Here, we investigated the functional role of another amino acid residues facing towards the nucleotide-binding pocket in the crystal structure of GroEL. A series of ATP hydrolysis mutants of GroEL, in which reaction cycle time is 8-sec ~ 6-days, have been constructed for application to DDS carrier.departmental bulletin pape
