Flavor violating Higgs signals, such as the top FcNc decay t→ch0 and the LFV Higgs decay h0→τμ, have been studied at the LHc. These signals can arise within the general Two-Higgs Doublet Model （THDM）, where each Higgs doublet couples to all fermion types through Yukawa matrices Yf 1 and Y f2 . The Yukawa matrices can be assumed to have the same form or they could have different structures. In this paper we study the case when both Yf1 and Y f2 have completely different forms, but in such a way that they complement to produce a specific hermitian mass matrix. We find that for specific four-zero textures, the flavor violating Higgs couplings depend only on the free parameters tan β, γf and the fermion masses. We use the current bounds on the low energy processes to derive constraints on the heavy Higgs boson mass, tanβand γf Then, we use these constraints to evaluate the LFV Higgs decays, which reach branching ratios that could be tested at the LHc.

The sulfurous water deposit exploitation in volcanic, swamp, or wetland regions, represents an alternative option for potable water supply in cities and communities around the world. However, before its consumption, it must be treated by the application of physicochemical or biological methods with the ability to separate high contents in sulfates, hydrogen sulphite and sulphides which have laxative, allergic and toxic properties in humans. conventional methods require the supply of chemical compounds or the adequate control of different parameters such as pH, temperature, etc., and the constant maintenance within their reactors. For these reasons, the systems could have elevated operating costs and require additional steps to enable the treatment of its separated products and the final disposal of its residual waste generated. In this research, compound parabolic collectors are implemented for the use of solar energy radiation, UV-B type, in Solar Advanced Oxidation Processes in H2O2/O3/UVsolar homogeneous phase. Its application during the pre-treatment of four sulfur water wells from the region of puebla, Mexico, demonstrated its ability to transform their sulfur compounds in sulfates of easy removal by a later stage of reverse osmosis, in an approximately 15 min treatment time process.

In this work, thin films growth at different ZnNO3 concentrations: 0.02 M, 0.03 M and 0.04 M by chemical bath deposition (cBD) as-prepared on glass substrates at 80 °c ± 2 °c. Patterns Diffraction x-ray (DRX) shown peaks 2θ = (31.72, 32.769, 34.36, 36.10, 47.44, 56.52, 62.78, 67.84 and 69.02), at concentration 0.02 M show formation from hydrozincite [Zn5(cO3)2(OH)6]. The optical band gap shifts from 3.8 eV to 3.6 eV. Photoluminescence (PL) spectra show intensity variation of the green emission (GE) may be resulted from variation of the intrinsic defect in ZnO films, such zinc vacancy (VZn), oxygen vacancy (VO), and interstitial zinc (Zni), interstitial oxygen (Oi). The presence of defects in our samples is responsible for the observed broad visible PL bands; this indicates reductions of oxygen vacancies and increase of oxygen interstitials. It could be believed that the presence of defects in samples is responsible for the observed broad visible PL band. The concentration increased the visible defect luminescence, which might be due to improvement to sample stoichiometric. The presence of both green emission (GE) and yellow emission (YE) can be seen through the deconvolution of the defect increasing the concentration, the position of the GE shifted from 1.96-2.45 eV and the increase of its intensity. The shifts of these two visible PL bands might be due to changes in local environments of the defects centers in samples due to increased concentration. Therefore, the GE relate to donor levels dominated due to increase of oxygen vacancies. ZnO is an n-type semiconductor and it means that most defects are Zn interstitials and oxygen vacancies. Raman spectra showed increase of the 437 cm-1 (E2 mode) peak intensity due concentration 0.4 M.

The growth of nanocrystalline PbS films by chemical bath deposition （cBD） onto glass at temperatureT = 40 ± 2℃, is presented in this research. We report on the modification of structural, optical nanostructures due to in situ *** morphological changes of the layers were analyzed using AFM. XRD spectra displayed peaks at 20 = （26.00, 30.07, 43.10, 51.00, 53.48）, indicating growth on the zinc blende face. The grain size determined by x-rays diffraction of the undoped samples, was found -36 nm, whereas with the doped sample was 32-23 nm. Optical absorption, transition direct and indirect the forbidden band gap energy （Eg） shifts discloses a shift in the range 1.45-2.4 eV.

Using zinc oxide (ZnO) powder and quartz rods as solid sources and molecular hydrogen (H2) as reactant gas, ZnO: SiOx composites were grown by hot filament chemical vapor deposition (HFcVD) technique. The absorbance spectra showed the formation of ZnO: SiOx composite in the studied temperature range. The crystalline quality of the ZnO lattice in the structure of the composite gradually lost by increasing the substrate temperature. Visible emission from blue to near-infrared region was found in the photoluminescence spectra of the composite formed at 1,100 °c. The contribution of blue, green, yellow and orange emissions present in the photoluminescence spectra of the composite formed at 1,100 °c was attributed to recombination centers produced by the presence of point defects in the structure of ZnO network. This result suggests that the ZnO in the ZnO: SiOx composite obtained at substrate temperature of 1,100 °c has an amorphous phase.

cdS, cdSe and PbS films were grown onto glass by chemical bath deposition (cBD). Different constant deposition temperatures (Td) were employed in the range 0-80 °c with subintervals of 10 °c. concentration of reagents, pH, and stirring were maintained constants. A microcrystalline mixture cdcO3 and cdS were grown. At intermediates Td values a mixture of both materials present. i. e., For Td? 40 °c, the intensity of the main of X-ray Diffraction (XRD) cdS peak is abruptly reduced. By scanning electronic microscopy (SEM) with Td = 80 °c, concentration atomic: cd = 49.10, S = 51.90, for Td? 70 °c, increase of carbon and oxygen. The cdSe, average grain size (GS) increased monotonic with Td, reaching saturation of 70 °c, with GS values of 5-16 nm. At low Td values (0-20 °c), the structural phase was found, and the high Td = 70 °c on material 5-16 nm was appreciated transition to phase: Wurzite (W)? Zinbclende (ZB) and phases mixture: W/ZB, grain size (GS) 9-27 nm. By (XRD), PbS grow in W phase at all films, for Td = 60 °c, was observed preferential orientation in plane [111] with (GS) of 19-26 nm also a Gibbs free energy calculation is included.
