Abstract. Absorption cross sections of emerging greenhouse gases (GHGs) were measured to estimate the radiative efficiency using high-resolution Fourier transform infrared spectroscopy (HR-FTIR). For quantitative spectroscopy, Beer–Lambert parameters absorber pressure, temperature, and optical path length (OPL) accurately determined be traceable primary standards. The OPL multipass cell mounted...

Borosulfates are an expanding class of silicate-analogous materials. We report the syntheses and crystal structures two unconventional cadmium borosulfates. Cd[B2O(SO4)3] crystallises in a new structure type space group Pnma (no. 62, a=896.92(8), b=1152.0(1), c=872.75(8) pm, 1380 refl., 94 ref. param., wR2=0.112). Cd4[B2O(SO4)6] adapts α-Mg4[B2O(SO4)6]-type with P 147, a=822.22(4), c=797.88(5) ...

The temperature dependence of the heat capacity CoFe 2 O 4 ferromagnet and 0.3CoFe -0.7PbTiO 3 multiferroic composite in range 150-820 K has been studied. over a wide range. It is noted that additional component due to transition cobalt or iron ions higher energy levels, as well distortion lattice parameters appearance three coexisting phases. Keywords: capacity, composite, Schottky effect.
