Calculate the absorbance at 280 nm that is expected for a 17 microM solution of peptide GRAYISH, if a 10-cm cuvette is used. For the extinction coefficient, take into account that e280(Trp) = 5690 M-1 cm-1 and e280(Tyr) = 1280 M-1 cm-1.
Iron nanoparticles were produced by the evaporation method and their average sizes are estimated 25,50, 90 and 120 nm using the laser particle analyzer. Assuming that the resultant particles are strain freeand the peak broadening detected in the measurement with Cu-K radiation (λ=0.154 nm) arises onlyfrom variation of size of the crystallites, estimate the peak width (the value of FWHM) of the (110) plane.
An amino acid on the surface of a protein was labelled covalently with 1.5-I AEDANS and another was labelled covalently with FITC. The fluorescence quantum yield of 1.5-I AEDANS decreased by 10 per cent due to quenching by FITC. What is the distance between the amino acids? (Refer to Table 17G.3 for the appropriate value of R0.)

5.4.5 Chemical microanalysis5.4.5.1 Exploitation of characteristic X-raysElectron probe microanalysis (EPMA) of bulk samples is now a routine technique for obtaining rapid, accurate analysis of alloys. A small electron probe (100 nm diameter) is used to generate X-rays from a defined area of a polished specimen and the intensity of the various characteristic X-rays measured usingeither wavelength-dispersive spectrometers (WDS) or energy-dispersive spectrometers (EDS). Typically the accuracy of the analysis is š0.1%. One of the limitations of EPMA of bulk samples is that the volume of the sample which contributes to the X-ray signal is relatively independent of the size of theelectron probe, because high-angle elastic scattering of electrons within the sample generates X-rays. The consequence of this is that the spatial resolution of EPMA is no better than ¾2 µm. In the last few years EDX detectors have been interfaced totransmission electron microscopes which are capable of operating…
A Raman spectrum of undoped GaAs at room temperature is performed with a 514.5 nm laser. The spectrum of scattered light exhibits peaks at wavelengths of 507.1 nm and 591.6 nm due to interaction of the incident light with LO phonons. Calculate the LO phonon frequency and the ratio of the intensity of scattered light at 507.1 nm to that at 591.6 nm.
