The purpose of this paper is to study a ink surface morphology, quantify the chemical composition involved in processing of graphite ink printed by flexographic printing. The methodology is to use surface sensitive technique, X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) and Field Emission Scanning Electron Microscopy (FESEM). As a finding we successfully achieved 25 micron lines array using PDMS printing plate. The Originality and value of this work is surface sensitive techniques like XPS, AFM and FESEM were exclusively used in order to characterize graphite inks printed by flexographic method, using PDMS printing plate.

AbstractIn this paper, the suitability of DNA- and RNA-bases, nucleosides and nucleotides, and DNA itself as structure-directing agents for the mineralization of ZnO-based materials is discussed. Those bioorganic molecules are able to trigger the morphology of mineralization products ranging from smooth, homogenous thin films to sponge-like, sheet-like and fibrous products. Besides the investigation of morphological features by scanning electron microscopy, the structural characterization of these materials by X-ray diffraction, vibrational spectroscopy, photoluminescence spectroscopy and photoelectron spectroscopy is discussed.

The utilization of cottonseed meal products as valuable industrial materials needs to be exploited. We have recently produced water-washed cottonseed meal, total cottonseed protein, sequentially extracted water- and alkali-soluble proteins, and two residues after the total and sequential protein extractions at a pilot scale. In this work, the surface characteristics of the six cottonseed meal products were examined by scanning electron microscopy (SEM), scanning electron microscopy- energy dispersive spectrometer (SEM-EDS), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results showed that the surface properties of the six products differed from those of a commercial soy protein flour examined comparatively in this work. The compact morphology and relative-high N composition were observed in all three protein products, with greater similarity between the total protein and alkali-soluble protein. The surfaces of the two residue products were more porous with polysaccharide features. Washed cottonseed meal possessed the surface features similar to those of the residues. In the meantime, the N-associated functional groups were under-represented in the surfaces of all samples, compared to their bulk composition. Information derived from this work increased the understanding of the surface functional properties of cottonseed meal products, which would benefit their practical utilization.

AbstractCu-rich Cu(In, Ga)Se2 (CIGS) films were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive x-ray fluorescence spectroscopy (EDX) and x-ray photoelectron spectroscopy (XPS). The Cu-rich CIGS film were treated in KCN and NH3 solutions. In the as-deposited Cu-rich CIGS film, the cation ratio of Cu/(In+Ga) at the surface exceeded the bulk value. Cross-sectional TEM of the KCN-treated film suggested that Cu2-xSe existed both at the grain boundaries and on the grains near the surface of the Cu-rich CIGS film. The Cu2-xSe was completely removed by the treatment in the KCN solution and was removed only at the front surface by treatment in the NH3 solution.
