Photoluminescence and Structural Analysis of Er3+/Yb3+/Tm3+ Triply Doped Gd2O3
(Brazilian Chemical Soc, 2017-01-01)
Spectroscopic and structural properties of Er3+:Yb3+:Tm3+ triply doped Gd2O3 nanocrystals were investigated. The effect of heat treatment at 800, 900, 1000 and 1100 degrees C for 4h, on the luminescence and the energy ...
Differential expression and accumulation of 14-3-3 paralogs in 3T3-L1 preadipocytes and differentiated cells
(Elsevier B.V., 2016-09)
The 14-3-3 protein family interacts with more than 2000 different proteins in mammals, as a result of its specific phospho-serine/phospho-threonine binding activity. Seven paralogs are strictly conserved in mammalian ...
Functional analysis of Paracoccidioides brasiliensis 14-3-3 adhesin expressed in Saccharomyces cerevisiae Microbe-host interactions and microbial pathogenicity
(2015-11-04)
Background: 14-3-3 proteins comprise a family of eukaryotic multifunctional proteins involved in several cellular processes. The Pb14-3-3 of Paracoccidioides brasiliensis seems to play an important role in the Paracoccid ...
Evidence of hetero-epitaxial growth of Pb(Mg1/3Nb2/3)O-3 on the BaTiO3 seed particles of a citrate solution
(Elsevier B.V., 2003-01-30)
Citrate solution was employed in preparing Pb(Mg1/3Nb1/3)O-3 (PMN) powder from polymeric precursors. BaTiO3 particles of 600 nm average size were used as seed for growing PMN. X-ray diffraction (XRD) indicated the presence ...
PTEN Regulates PI(3,4)P2 Signaling Downstream of Class I PI3K
(2017-11-02)
The PI3K signaling pathway regulates cell growth and movement and is heavily mutated in cancer. Class I PI3Ks synthesize the lipid messenger PI(3,4,5)P3. PI(3,4,5)P3 can be dephosphorylated by 3- or 5-phosphatases, the ...
Paracoccidioides brasiliensis 14-3-3 protein is important for virulence in a murine model
(2019-10-01)
The Paracoccidioides brasiliensis strain downregulated the expression of adhesin Pb14-3-3 (Pb14-3-3 aRNA) was evaluated in a murine model of paracoccidioidomycosis (PCM). Pb14-3-3 aRNA displays attenuated virulence and ...
Time dependence and energy-transfer mechanisms in Tm3+Ho3+ and Tm3+-Ho3+ co-doped alkali niobium tellurite glasses sensitized by Yb3+
(Elsevier B.V., 2001-05-01)
Glass samples with the composition (mol%) 80TeO(2)-10Nb(2)O(5)-5K(2)O-5Li(2)O, stable against crystallization, were prepared containing Yb3+, Tm3+ and Ho3+. The energy transfer and energy back transfer mechanisms in samples ...
Theoretical study of complexes of the type [Pt3(M-L) 3(L')3]-X (L=CO, SO2,CNH; L'=PH 3,CNH; X=Tl+, Hg0, MPH3+ (M = Cu, Au, Ag))
(Sociedad Chilena de Quimica, 2013)
The interaction between the [Pt3(μ-L)3(L') 3] cluster (L = CO, SO2, CNH; L' = PH3, CNH) and a series of fragments X (Tl+, Hg(0), AuPH3+, CuPH 3+ and AgPH3+) was studied using ab initio methodology. The calculations suggest ...
Structure, morphology and photoluminescence emissions of ZnMoO4: RE 3+=Tb3+ - Tm3+ - X Eu3+ (x = 1, 1.5, 2, 2.5 and 3 mol%) particles obtained by the sonochemical method
(2018-06-25)
ZnMoO4 and ZnMoO4: RE3+ = 1% Tb3+, 1% Tm3+, x Eu3+ (x = 1, 1.5, 2, 2.5 and 3 mol%) particles were prepared by a sonochemical method. The influence of the dopant content on photoluminescent behavior was investigated. The ...
NH3+N2O3 reaction. High level calculations
(Elsevier B.V., 2006-02-14)
We have undertaken a comprehensive study of the NH3 + N2O3 reaction in gas phase. Total energies of reactants, intermediates, transition states, and products have been calculated at CBS-QB3 level of theory. The corresponding ...
