WebDec 13, 2024 · Wavefunction-based ab initio theory (WFT) and density functional theory (DFT) are the two primary approaches of electronic structure. WFT methods can approach exact solutions of the Schrödinger equation to almost arbitrary accuracy (see, e. g., Refs. [1–4] and references therein). WebAn IOZ silicate primer has approx 40-50% of pores ...read more An IOZ silicate primer has approx 40-50% of pores by volume and dries so quickly that accurate WFT readings are uncertain. Hence, my practical way is to use mock-up plates before the actual application and judge the dft achieved per pass, or number of passes needed to achieve ...
