• band gap is evaluated using K–M function as follows [27]: where F(R∞) is the K–M function or re-emission function, R∞ is the diffuse reflectance of an infinitely thick sample, K(λ) is the absorption coefficient, s(λ) is the scattering coefficient, hν is the photon energy and Eg is the band gap energy

• (energy dependent) intensity of incident X-rays and μ is the absorption coefficient. Since for photon energies below 20 keV the photoeffect dominates over Raleigh and Compton scattering, μ can be approximated by the photoabsorption coefficient, which is proportional to the absorption cross-section. The

• reality the heat loss cannot be neglected. The heat loss through the IR window can be calculated for defined boundary conditions. A high IR absorption coefficient of the liquid in the cavity causes the absorption of the IR energy within a very small absorption zone. For water as a liquid with a very high

• IR absorption coefficient, a formula for the temperature profile ΔT(z) could be derived [27] on the assumption of a infinitely thin boundary layer between the glass window and the water. This allows a numerical solution of the mean temperature increase in Equation 4 taking into account the heat loss

• have a significant lower absorption coefficient which requires the application of an additional absorber such as plastic, aluminium, antimony or lead [21]. When the absorbing film is directly on the inner surface of the window, the assumption of a boundary layer as in the case of water is valid

• reduction rate of DCPIP at 595 nm in accord with the previously described procedures [33][34]. The reaction mixture was composed of 0.1 mM DCPIP, 100 mM L-proline and enzyme in Tris-HCl buffer (0.3 M, pH 7.5) with a total volume of 3.0 ml. The molar absorption coefficient of 2.15 × 104 M−1 cm−1 was used to
