A 1.2cm diameter glass cuvette is filled with a Cu(NH3)42+ solution that is deep blue. The cuvette is placed into a pre-blanked spectrophotometer. At 620nm, the transmittance is 23%. If the solution has molarity = 0.0133 M and path length of light through the solution = 1.2 cm, what is the value of molar absorptivity at 620 nm?
7 A rectangular surface of 4 m2 was exposed to solar radiation of 1400 W/m2. The temperature of the surface was maintained at 500K. The spectral absorptivity of the surface is given as 0 for 0> λ (μm) < 0.5, 0.8 for 0.5> λ (μm)< 1, 0 for 1< λ (μm) < 2, and 0.9 for λ (μm)>2. Assuming the surface is diffuse and the sun temperature is 5800K, calculate the absorbed irradiation, radiosity, and net radiation heat transfer from the surface.
The molar absorptivity for aqueous solutions of phenol at 211 nm is 6.17 × 103 L cm-1 mol-1. Calculate the permissible range of phenol concentrations if the transmittance is to be less than 85% and greater than 7% when the measurements are made in 1.00-cm cells.
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…
