Scatter band

SPR biosensors are label-free detection devices - binding between the biomolecular recognition element and analyte can be observed directly without the use of radioactive or fluorescent labels. In addition, the binding event can be observed in real-time. SPR affinity biosensors can, in principle, detect any analyte for which an appropriate biomolecular recognition element is available. Moreover, analyte molecules do not have to exhibit any special properties such as fluorescence or characteristic absorption or scattering bands. [Pg.108]

Figure 47 shows taken from Equation 20 versus Vj. It shows that S. is quite sensitive to Vp and is therefore a good means to evaluate v, with the numerical values of Fig. 47. It can be estimated that the tensile modulus E of the bulk PMMA is not affected by the very low pressure toluene gas environment during the short duration of the experiment. The optical craze index in PMMA in air without load is known as n = 1.32, which corresponds to v = 0.6. From the optical interferometry, it is known that the craze just before breakage is twice as thick as unloaded, (v, = 0.3) and hence using Lorentz-Lorenz equation its optical index is n = 1.15. From Figs. 46 and 47 it can be concluded that the bulk modulus around the propagating crack is about 4400 MPa, which is a somewhat high value, in view of the strain rates at a propagating crack tip (10 to s" ). Using the scatter displayed in Fig. 46, it can be concluded from Fig. 47 that the fibril volume fraction is constant, v = 0.3, within a scatter band of 0.08, and is therefore not sensitive to the toluene gas.

The Raman spectra of the Si02 nc-Si system measured at different depths by the NTEGRA-Spectra platform are shown in Fig. 2. Besides the broad scattering band from fused quartz, the nc-Si-related peak at 515-520 cm" is clearly... [Pg.82]

An unidentified compound of pharmaceutical interest was reported to be able to exist in two polymorphic forms, each of which exhibited distinctive Raman spectra.71 A series of calibration samples were prepared over the Form-A range of 1.8-15.4% w/w in Form-B, and a calibration curve developed using the characteristic scattering bands at 1716 cm-1 (Form-A)... [Pg.53]

For strength, the low-molybdenum German steel 15 Mo 3 is, like the chromium-molybdenum grades, reported to be lower than Grade PI over 1,000°F. On tiie other hand, the minimum specified yield strength is within the scatter band for the ASTM material. [Pg.303]

The correlation between the total phase enthalpy and the Young s modulus, which is one of the three elastic moduli, is shown in Fig. 6 for various cubic phases, i.e. for the f.c.c. elements Al and Ni (Al), the f.c.c.-ordered NijAl (LI 2), the b.c.c. ordered FeAl, NiAl and CoAl (B2), and the cubic Laves phases CaAlj, YAI2, LaAl2, NbCr2, ZrLaves phases, i.e. there seems to be a common scatter band and the data of some other phases are near this scatter band. It has to... [Pg.10]

In order to confirm and study in situ the respective conformational changes of DNA in the adsorbed state, the SERS spectroscopy was applied later Native DNA exhibits some 30-40 normal solution Raman scattering bands in the spectral range of 200-1800 cm iss.ise) jj g more intense bands are caused by vibrations of the base residues adenine (A), guanine (G), cytosine (C) and thymine (T). [Pg.21]

Both the H2S concentration over the range of 0-1.0 v/o of the CGA gas and the temperature controlled the measured corrosion rates. Figure 1 illustrates the effect of temperature on corrosion rates of several alloys and coatings in the CGA gas containing 1 v/o H2S. Alloys AISI 309, AISI 310, and IN-800 demonstrate a clear temperature dependence of total oxidation-corrosion in 1000 hr. The 309 alloy had a scatter band of 5 to 125 mils total metal loss for four specimens at 1650°F. This is typical of borderline alloys that undergo time-dependent transitions to accelerated corrosion rates. Total corrosion of aluminized 310 and 800 was relatively unaffected by temperature over the range of 1500°-1800°F for 1000 hr exposures. [Pg.397]
