Photocatalytic oxidation is promising technology for removal of recalcitrant pollutants from water.Solar energy can be an interesting radiation source since the operating costs can be lower.However, the use of powder photocatalyst is a major drawback of the technology since suitable separation technologies are required and catalysts recovery is dif
Extending two Higgs doublet models for two-loop neutrino mass generation and one-loop neutrinoless double beta decay
We extend some two Higgs doublet models, where the blackmores ache relief focus review Yukawa couplings for the charged fermion mass generation only involve one Higgs doublet, by two singlet scalars respectively carrying a singly electric charge and a doubly electric charge.The doublet and singlet scalars together can mediate a two-loop diagram to
