The article considers the sorption-frequency method (SFM) for measurement of gases and liquids humidity in comparison with other methods, which are widely applicable today. These methods are shortly described with their advantages and disadvantages. The conclusion about possibility or impossibility to apply each method for measurement of moisture nanoconcentrations is made. In the end of the article...
The KPb2Cl5 and KPb2Br5 crystals are monoclinic (P21/c) with a microtwinned structure. X-ray analysis of chloride resulted in the parameters a = 8.854(2) Å, b = 7.927(2) Å, c = 12.485(3) Å; β = 90.05(3)°, dcalc = 4.78(1) g/cm3 (STOE STADI4, MoKα, 2θmax = 80°), R1 = 0.0702 for 4094 F ≥ 4 σ(F) reflections. For bromide, a = 9.256(2) Å, b = 8.365(2) Å, c = 13.025(3) Å; β = 90.00(3)°, dcalc = 5.62(1)...
