IN-SITU OBSERVATIONS OF CATALYTIC SILICON NANOWIRE AND CARBON NANOTUBE CVD
The molecular replacement solution was found using two independent search models; the first was the structure of the BTCI trypsin complex (PDB code 2g81) and the second was chymotrypsin (PDB code 4cha). It may shed light on the differences between the pKa of peroxidated cysteines from the two cytosolic TP isoforms and contribute to the understanding.

INFLUENCE OF THE CONTENT OF PRAZIQUANTEL ON STRUCTURAL FEATURES OF THE LIPOSOMES
A further one has a similar atom position to the t form and a later one has an axial ratio, c/a, of unity with the oxygen atoms displaced from their positions in the cubic phase. In previous work done at LNLS, we found that the metastable t”-form of the tetragonal phase or cubic (depending on the composition) can be retained in nanocrystalline powders. These experiments were performed at the D10B - XPD LNLS beamline operating in high intensity mode.
All powders exhibited phase transitions in the temperature range considered in this study (25 to 900◦C) and we proved that the transition temperature depends on the crystallite size and dopant content.

The Carriqueo Rock Shelter is located on the west side of La Oficina Canyon, a tributary of the Limay River, in the Pilcaniyeu area, in the province of R´ıo Negro. These can be made not only from the substance that produces the color, but also for other chemical additives. The proportion x of Li+1 ions determines the surface charge of the platelets, which are held together in the folded structure by an intermediate cation.

The addition of ZnPc and ClAlPc in condensed CPN also revealed the presence of two values for a. The results showed that the amphiphilic PpIX is not localized within the lipid bilayers, while the hydrophobic ZnPc and ClAlPc are localized between the lipid bilayers in the hexagonal phase. The presence of HEC allowed the entrapment of ZnPc and ClAlPc in the lipid domains of the cubic phase.
ZnPc is not trapped in the lipid domain of CPN, but the presence of.

They studied the influence of 57Fe doping and deformation effects on the structural and magneto-transport properties of undoped and lightly 57Fe-doped (1 and 3% on the Mn site) La2/3Ca1/3MnO3 thin films and samples in bulk powder. M¨ossbauer (CEM) electron conversion spectra measured at room temperature in the paramagnetic regime of Fe-doped samples do not show significant differences in the isomeric shift in the case of La2/3Ca1/3MnO3 films doped with 1 and 3%. The isomeric shift values correspond to the presence of Fe in the 3+ state with octahedral coordination, indicating that Fe is incorporated into the structure by Mn substitution.
The absence of further states in the spectra indicates that Fe is not involved in the formation of other additional impurity phases.

CeO 2 solid solutions synthesized by different chemical routes: crystal structure and local order
In particular, the electrical and catalytic properties are closely related to the crystal structure of the powders. We found that the crystallite size and morphology of the powders were strongly influenced by the synthesis method. From the characteristic binding energies of the photoelectron, the relevant elements can be identified and the peak intensity can be directly related to the atomic concentration in the sample surface.
Four of the alloys were fully amorphous and seven presented an amorphous matrix with scattered nanocrystalline regions.
The thermal expansion of metallic silicides has been investigated for potential applications to high temperature construction materials. Because these silicides crystallize in non-cubic structures, their thermal expansion coefficients are usually anisotropic. The aim of this study was to determine the thermal expansion coefficients and anisotropy for Cr5Si3 and Ta5Si3.
The thermal expansion coefficients and anisotropy for Cr5Si3 and Ta5Si3 were calculated through the variation of the lattice parameters.
RADIATION DAMAGE AND RADIATION INDUCED OXI - REDUCTION OF Eu IONS IN RARE EARTHS
Alguns materiais com coeficiente de expansão térmica negativo (ou próximo de zero) amorfizam em altas pressões, mas a correlação entre os dois fenômenos ainda é motivo de debate. O comportamento de alta pressão do Fe[Co(CN)6] foi investigado por um conjunto de técnicas complementares de análise in situ: difração de energia dispersiva e dispersiva de raios X. angular (tubo de raios X convencional), absorção infravermelha, espectroscopia Raman e espectroscopia de absorção de raios X (radiação síncrotron). A fase amorfa formada a altas pressões é retida após o alívio da pressão.
Uma série de resultados indicam que a amorfização induzida por altas pressões em Fe[Co(CN)6] está associada a um processo de decomposição que forma a matriz CNx e possivelmente nanopartículas de células Fe/Co.
ELECTRONIC PROPERTIES OF COORDINATION COMPOUNDS OF THE DMIT, DMIO AND DMT
O uso da conscientização na medicina tem se destacado, principalmente à luz de uma modalidade alternativa de tratamento do câncer chamada terapia fotodinâmica (PDT). Neste trabalho, as características estruturais de amostras dos insumos farmacêuticos fluconazol, mebendazol e nimesulida foram investigadas utilizando técnicas de difração de raios X de pó (DRXP) e análise térmica. A estrutura atômica desta liga foi determinada por difração de raios X (XRD) como sendo do tipo blenda de zinco (ZB-GaSb), e suas propriedades térmicas e ópticas foram investigadas através de calorimetria (DSC) e espectroscopia Raman (RS) [1 ] .
A transição semicondutor-metal da liga sob pressão foi verificada por absorção de raios X (XAS) e Raman [2].
EFFECT OF THE STATE OF METALS OXIDATION ON POLYSULFUR LIGANDS
The results obtained from transmission electron microscopy, scanning electron microscopy, atomic emission spectroscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, infrared and Raman spectroscopy made it possible to conclude that the layers of both as-synthesized titanates nanotubes and nanoribbons are - tural to theN a2T i3O7lamellar compound. In the titanate nanotubes, the chemical bonds are deformed due to the curvature of the walls, while the layers in the titanate nanoribbons exhibit structural disorder due to size effects. The thermal behavior of titanate nanoribbons is similar to those reported in the literature for titanate nanotubes, where structural and morphological changes with temperature increases are observed and indicated that at high temperatures the nanoribbons change to bulk with a phase mixture of N a2T i3O7 and N a2T i6O13.
We thus conclude that the chemical composition of both the titanate nanotubes and the titanate nanoribbons is the same, N a2−xHxT i3O7.nH2O (0≤x≤2).

ESTRUTURA MAGNETICA DO INTERMETALICO TbCo2B2C
This sparked an active interest in researching the ternary phase diagram of the Al-Ni-B system. There is almost no information on the physical properties of stable Al-Ni-B ternary compounds. This suppression is believed to be due to the different electronic structure of Cu2+ associated with Li1+ ions.
The application of this compound is closely related to the morphology, the amount of water in the layered structure (n) and the oxidation state of the vanadium atom.
