Figure 3. AFM images of the silver nanoparticles on the Xi02(l 00) single crystal at the deposition times of (a) 15s and (b) 180 s. The images were recorded in a tapping mode with driving frequency of 110-150 kHz at a scan rate of 1 Hz by using a silicon cantilever with a normal spring constant of 15Nm (SI-DF20, Seiko instruments).

QCM measurements were carried out at air using AT-cut gold-coated quartz crystals with a resonant frequency of 9 MHz (5 mm-diameter, Seiko EG Q Seiko Instruments Inc). Prior to use, the quartz crystals were cleaned with water and ethanol. The frequency was measured before and after the monolayer transfer with the use of a Seiko EG G model 917 quartz crystal analyzer.

Figure 6. Compilation of TG/DTA responses for the crystallization of the amorphous alloy PdjjZr which was prepared by the melt-spinning technique. The red data were obtained in hydrogen, the blue data in oxygen. The responses in hydrogen are enlarged by a factor of 10, the enlarged weight curve by a factor of 100 relative top the ordinate scales. A SEIKO instrument was used and gas flows of lOOmlmin-1 were adjusted for sample masses of ca. 4 mg.

Leakless sealed cells and sealing device are now available from Seiko Instruments Inc. and Nippon Kayaku Co., Ltd. 

DSC(3) data were obtained with a Model DSC-200 apparatus (Seiko Instruments Inc.) at the Koriyama Plant of Nippon Peroxide Co., Ltd. The sample cell used was a sealed cell supplied from Seiko Instruments Inc. Tdsc(3) and Qdsc(3) were determined directly by the processor supplied with a DSC apparatus. 

As has been discussed, several requirements must be met to predict the explosiveness of self-reactive substances on the basis of the results of measurements by SC-DSC. First, a leak-free sealed cell must be used that is sufficient pressure-proof. Such cells are available from Nippon Kayaku Co. and Seiko Instruments Inc. Next, correct peak areas must be measured. Determination of correct exothermic peaks is one requisite for this purpose, and it is necessary to acquire some experience in this task. 

As shown in Fig. 4.8.1, a TG apparatus typically consists of a (1) recording balance, (2) furnace, (3) furnace temperature controller, (4) temperature programmer, (5) temperature detector, and (6) recorder. Most commercial models, e.g., Perkin-Elmer Model TGA-7, TA Instruments 2950 TGA, Mettler TC11ATG50, Seiko Instruments SSC 5200 TG-DTA 220, and Shimadzu TGA-50, consist of these basic components. 

Built-up films have been obtained by the vertical lifting method at room temperature with a 105 type LB trough. The IR spectra were recorded on a Nicolet FI-IR spectrometer, the UV-Vis spectra were measured using a Perkin-EImer 330 spectrometer whereas the SAXD measurements were performed on a D/Max-rA X-ray diffractometer (CuKa radiation with A = 0.15405nm). The AFM images were obtained on an SAP 400 (Seiko Instrument Inc.) microscope. 

The contents of sodium, nickel and manganese in the samples were determined by Seiko Instruments SPS7000A induced couple plasma (ICP) spectrometer after dissolved in a mixed solution of HCl and H2O2.

The Chitopearr resin was packed in a glass column (inner diameter 1. 4 cm, bed height 4.3 cm). The column was first equilibrated with a 20 mM MES buffer containing 20 mM NaCI and 10 mM 2-mercaptoethanol. Then 60 ml of the MES buffer containing metal ion was applied at the flow rate of O.S ml/min. Adsorption capabilities of the ligands were examined for cadmium, gallium, cupric, zinc, or nickel ion. After the column was washed with MES buffer, the adsorbed metal ion was eluted with the MES buffer (pH of which was adjusted to pH 2.0). In order to examine effects of pH on the adsorption, pH of the MES buffer was varied from pH S to pH 9. The eluted solution was collected as several fractions of 10 ml each, and the metal concentration of each fraction was determined with atomic adsorption analysis (SAS 7S00A, Seiko Instruments, Japan). Total amount of the eluted metal ion was defined as the adsorbed metal ion on the resin. The total amount of the adsorbed metal ion was divided by the total amount of immobilized protein to calculate the number of metal molecules bound to one mole of the protein. The adsorption experiments were carried out multiple times, and the maximum experimental error was 25%. 

In parallel, a small quantity of lyophilized samples placed into DSC pans was also equilibrated in each chamber at controlled RH to be submitted to DSC analysis. At equilibrium, the pans were sealed and analyzed. Glass-transition temperature was analyzed in a DSC 5200 (Seiko Instruments Inc., Chiba, Japan). Heating rate was 5°C/min and temperature range varied between — 20 and 80°C. The midpoint of the glass transition was considered as the characteristic temperature of the transition. Determinations were carried out in triplicate. 

Thermogravimetry. Thermogravimetric analysis (TGA/DTG) was performed on a Seiko instrument. The samples were heated in platinum crucibles up to 1000°C with a heating rate of 3 C/mn in 60 mL/min under flowing dry air. 

Tensile properties were measured by using Shimadzu mechanical tester DSS5000. The cross head speed was 2 mm/min. Viscoelastic properties(tensile storage modulus and tan S) were measured by a tensile type dynamic mechanical analysis(SEIKO Instrument DMS 200). The...

Bulk Si/Ti ratios of titania/silicas were measured by X-ray fluorescence analyses carried out on a Seiko Instrument Co. SEA-2010. The X-ray photoelectron spectra were obtained with a Perkin Elmer ESCA5500 with a monochromatised Mg-Ka source. The Cls, 01s, Si2p, and Ti2p lines were investigated and their binding energies were referenced to the Cls line at 285 eV. The X-ray powder diffraction patterns were obtained on a MAC Science...

Figure 16.25 A schematic simultaneous TGA-DTA instrument. A weight change on the sample side displaces the beam and a drive coil current returns the beam to zero. The current is proportional to the weight change and serves as the TGA signal. The temperature change between the sample and reference pans is measured by thermocouples attached to the pans. The temperature differential is the DTA signal. (Courtesy of ThermoHaake, Inc., Paramus, NJ, www.thermo.com, and Seiko Instruments, Japan.)...

The late 1970s saw Polymer Laboratories develop their DMTA using dual cantilever bending, which works well for most small. samples from -150 C to the onset of melt. Shear, tensile, torsion, and simple compression options followed, as did the complementary Di-clectric Thermal Analyser (DETA), and computers were used from 1982 to both control and analyze the data. Seiko Instruments copied this and tried to patent it. and others such as Netzsch, Perkin-Elmer, and TA Instruments looked very closely at this before launching their own. For comparative data and fast thermal scans they all can give good data, but for absolute modulus numbers most systems need to consider the frame compliance, sample end corrections, and relative dimensions, and hence only a limited range of sample dimensions can be used for accurate measurement of modulus in a particular mode of deformation.
