Photocatalytic properties of CaBiVMO8 (where M = W and Mo) compounds

Dirac showed that the existence of one magnetic pole in the universe could offer an explanation for the discrete nature of the electric charge. Magnetic poles appear naturally in most Grand Unified Theories. Their discovery would be of greatest importance for particle physics and cosmology. The intense experimental search carried thus far has not met with success. Moreover, if the monopoles are very massive their production is outside the range of present day facilities. A way out of this impasse would be if the monopoles bind to form monopolium, a monopole-antimonopole bound state, which is so strongly bound, that it has a relatively small mass. Under these circumstances it could be produced with present day facilities and the existence of monopoles could be indirectly proven. We study the feasibility of detecting monopolium in present and future accelerators. Pacs: 14.80.Hv, 95.30.Cq,

Thespectraofmassesand decay constants for non-strange scalar mesons in the energy range 0-2.5 GeV is analyzed. It is known from meson phenomenology that for givenq uantum numberstheses pectraa pproximately followl inear trajectories with au niversal slope. Thesef acts can be understood in termso fa ne ffectivestringd escriptionfor QCD. Forlight meson states the trajectories deviate noticeably from the linear behavior.W ei nvestigate the possible corrections to thelinear trajectoriesbymatching two-point correlators of quarkcurrentstothe Operator Product Expansion(OPE). We findthat theallowed modifications to thelinear Regge behavior mustdecrease rapidly with the principal quantum number.A fterfi tting the lightests tates in each channel and certain low-energy constantsthe wholespectrumfor scalar meson massesand residues is obtained in asatisfactoryagreement with phenomenology.

“…From the viewpoint of solar energy utilization, numerous studies have focused on the development of photocatalysts with high activity under visible light irradiation [10]. Recently, a great number of novel photocatalysts showing certain visible absorption ability have been developed, such as InTaO 4 [11], Bi 2 WO 6 [12], AgAlO 2 [13], Bi 12 GeO 20 [14], CaBiVMO 8 [15], Bi 2 MoO 6 [16] and BiVO 4 [17][18][19]. BiVO 4 has attracted considerable attention for its well photocatalytic property under visible light irradiation [17,18].…”
