Nanocrystalline nickel powders were prepared with grain size 'd' in the range 40–100 nm diameters through polyol method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used for characterization. XRD of the prepared samples consistently matched with standard fcc structure of nickel without any impurity peak. Detailed analysis and calculations using Scherrer equation for (111) peak revealed systematic increase in line width and peak shifting towards lower diffraction 2θ angles with decrease in nickel to ethylene glycol mole ratio. Different values of d estimated from various peaks of each sample suggested associated microstrains in the nanograins. Values of d estimated from X-ray diffraction patterns were compared with those obtained from atomic force microscopy and scanning electron microscopy results, and discussed. Observed lattice expansion is explained, on the basis of a theoretical model of linear elasticity.

Polyaniline (PANI)–ZnO nanocomposite thin film has been successfully fabricated on glass substrates by using vacuum deposition technique. The as-grown PANI–ZnO nanocomposite thin films have been characterized using X-ray diffraction, Scanning Electron Microscopy, Atomic Force Microscopy, UV-visible spectrophotometer and Fourier Transform Infrared (FTIR) spectroscopy, respectively. X-ray diffraction of as-grown film shows the reflection of ZnO nanoparticles along with a broad peak of PANI. The surface morphology of nanocomposite films has been investigated using scanning electron microscopy and atomic force microscopy. The hypsochromic shift of the UV absorption band corresponding to π–π* transition in polymeric chain of PANI and a band at 504 cm –1 due to ZnO nanoparticles has been observed in the FTIR spectra. The hydrogen bonding between the imine group of PANI and ZnO nanoparticle has been confirmed from the presence of the absorbance band at 1151 cm–1 in the FTIR spectra of the nanocomposite thin films.

Through-pores alumina membranes of 50 μm thickness and 70 × 70 mm size have been fabricated to deposit Ni nanowires by electrochemical processing. Due to highly ordered microstructure of the membranes, the pores were filled by nanowires almost to 100%. The membrane nanowires composite morphology; structure and chemical features have been studied by scanning electron microscopy, atomic-force microscopy and X-ray structural analysis. To measure the specific magnetization σ as a function of temperature in the range of 77–1400 K, the pondero-motive method was used.

Uma nova metodologia de oxidação de superfícies de implantes de titânio foi desenvolvida com o intuito de remover previamente os óxidos primários formados espontaneamente durante a usinagem de peças de titânio. Com o objetivo de solucionar esse problema, utilizou-se neste trabalho o plasma como fonte energética tanto na remoção desses óxidos, como na oxidação de superfície de titânio. Nesse sentido, discos de Titânio tiveram seus óxidos previamente removidos por plasma com atmosfera de 50% Ar + 50% H2 seguidos da oxidação pela técnica de descarga por cátodo oco.  A oxidação foi realizada numa mistura de argônio (60%) e oxigênio (40%) até atingir a pressão de 220 Pa durante 60 min a 500°C. Em seguida caracterizou-se as superfícies oxidadas e controle por difração de Rx (X-Ray diffraction), microscopia de força atômica AFM (Atômic Force Microscopy) e microscopia eletrônica de varredura (SEM) (Scanning Electron Microscopy). Resultados obtidos por X-Ray rasante indicou que o processo de remoção dos óxidos foi eficaz, reduzindo TiO2 para Tia.  Com relação ao processo de oxidação, verificou-se que houve um aumento de 61% para 76% na concentração de O2 e a amostra oxidada apresentou-se rica em óxidos como TiO2. Na caracterização por AFM as amostras oxidadas apresentaram defeitos nas superfícies com geometria variada para picos e vales. As diferenças topográficas entre a superfície oxidada e controle são discutidas em termos das dimensões médias dos poros e dos parâmetros de rugosidade Ra, Rp e Rz. Ensaios biológicos foram também realizados com o intuito de observar a adesão e proliferação celular. No SEM observou-se espraiamento celular, uma maior quantidade de projeções de filopódios e diferenças morfológicas nas células das amostras oxidadas em comparação com a amostra controle. Na proliferação celular as células mostraram uma preferência por superfícies oxidadas onde o número de células aderidas foi comparativamente superior, em relação à amostra controle. Concluímos que o processo foi eficiente na remoção dos óxidos primários bem como na oxidação da superfície do titânio.

Modified montmorilonite additivated films of poly 3 (hydroxybutyrateco-8%-hydroxyvalerate) were formulated by solvent evaporation technique and then characterized by means of X-ray diffraction, scanning electron microscopy, atomic force microscopy and scanning differential calorimetry. A preliminary characterization using these analyses revealed the formation of nanocomposites with partially exfoliated and interlayered structures. These nanocamposites display changes in the crystalline structure of the precursor biodegradable polymer.
