Construction and Measurement of Normal Spectral Emissivity Device using Fourier Transform Infrared Spectrometer

Cobalt‐Mediated Radical Polymerization

“…Co(acac) 2 (3a; see Figure 4.1) is the most prolific complex for the preparation of block copolymers, until now. Indeed, the sequential CMRP of VAc with NVP [33], AN [48], or vinyl pivalate (VPi) [49] leads to the corresponding block copolymers, in controlled fashion. Throughout the polymerization, the experimental conditions were necessarily adjusted, taking into consideration the reactivity of the second monomer.…”

“…In this case, the DMF not only serves as the solvent but also binds the metal and adjusts its reactivity. As a rule, the PVAc sequences of these copolymers were hydrolyzed in order to provide poly(vinyl alcohol) (PVA)-containing derivatives, such as hydrosoluble PVA-b-poly -O(CO)tBu -CN [49] (N-vinylpyrrolidone) (PNVP) and amphiphilic PVA-b-PAN [33,48]. Hydrolysis of both the esters and the nitrile groups of the PVAc-b-PAN copolymers paved the way to a well-defined, pH-sensitive PAA-b-PVA compound [48,50].…”

IR radiometer sensitivity and accuracy improvement by eliminating spurious radiation for emissivity measurements on highly specular samples in the 2–25 μm spectral range

“…Several radiometer designs and different measurement methods (usually determined by the radiometer design) have been reported. See for example [12][13][14][15][16][17][18][19][20][21][22][23][24][25] and references therein. In this paper the theoretical equations refer to the blacksur method [26].…”
