This volume is part of the seventh set of Handbook of Porphyrin Sceince. Porphyrins, phthalocyanines and their numerous analogue and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorop…
Plasma treatment to wool fabrics is effective to the shrink-resistant performance without using chlorination and dyeing performance. The adhesive property between fabrics is growing by the treatment when we make two-layer fabric from face fabric and fusible interlining. During the process of apparel making, interlinin…
Transmission electron microscopy images of insulin-producing beta cells in the islets of Langerhans contain many complex structures, making it difficult to accurately segment insulin granules. Furthermore the appearance of the granules and surrounding halo and limiting membrane can vary enormously depending on the met…
Palladium atoms have been deposited onto graphene where they catalyse etching processes in conjunction with the e-beam, during/after which they reside at the edges of the holes, which have formed in the graphene. Energy filtered imaging reveals that the low loss feature at 2-4 eV constituting the shoulder of the graph…
The chain segment motion and charge trapping and detrapping in nylon 1010 films were investigated by means of thermally stimulated depolarization current (TSDC). There were three current peaks (named α, ρ1, and ρ2 peaks, respectively) in the experimental TSDC spectra above room temperature. The α peak is attributed to…
The structural and morphological features influencing the glass transition temperature of epoxy/silica nanohybrid and nanocomposite materials containing 25–30 phr of nanoscale silica phases are discussed in this letter to answer the questions related to the processing–structure–property relationships. X-ray photoelect…
Radiation damage in nuclear grade graphite has been investigated using transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS). Changes in the structure on the atomic scale and chemical bonding, and the relationship between each were of particular interest. TEM was used to study damage in n…
Due to conceptual difference between geometry descriptions in Computer-Aided Design (CAD) systems and particle transport Monte Carlo (MC) codes direct conversion of detector geometry in either direction is not feasible. The paper presents an update on functionality and application practice of the CATIA-GDML geometry b…
A new method of quantifying the HAADF STEM signal on absolute scale, building on the z-contrast nature of the technique, has been developed to address the problem of characterising nanoparticles to an atomic scale. Experimental images are scaled to a fraction of the incident beam intensity from a detector map. The int…
In the theory of ergodic one-dimensional Schrödinger operators, the ac spectrum has been traditionally expected to be very rigid. Two key conjectures in this direction state, on the one hand, that the ac spectrum demands almost periodicity of the potential, and, on the other hand, that the eigenfunctions are almost su…
A method for reducing the stress concentration in welded joints is proposed. The method is based on depositing a brazed bead in the weld zone produced from material with a melting point and elasticity modulus lower than those of the parent material. It is shown that zinc is the most efficient material for producing th…
Microwave-irradiation (MW) synthesis of nanostructured materials provides for the synthesis of metal nanoparticles, using fast and uniform heating rates. This procedure affords better control of the shape and size of the nanoparticles when compared to conventional methods. In this work, microwave-irradiation was used…
The impact of graphitisation-type processes on the carbon K -edge ELNES is explored for model systems using the CASTEP density functional theory code. For c lattice direction expansion, contraction of spectral peaks occurs between 20 and 27 eV above the edge onset, for a/b lattice dimension expansion spectral peaks ar…
An analysis technique for an ultra shallow junction in shrunk semiconductor devices was developed using medium energy ion scattering (MEIS) time‐of‐flight (TOF) elastic recoil detection analysis (ERDA). The energy of the recoiled and forward‐scattered ions was analyzed using a toroidal electrostatic analyzer with an e…
We optimized the culture medium for 3-hydroxycarboxylic acid production by Pseudomonas mendocina DS-04-T-biodegraded polyhydroxybutyrate (PHB) using the Plackett-Burman design, steepest ascent method, and Box-Behnken design. The optimized concentrations of the constituents of the culture medium were as follows: PHB (7…
All‐perovskite‐oxide heterojunctions composed with tetravalent cation‐doped La0.9Hf0.1MnO3 (LHMO) and 0.7 wt% Nb‐doped SrTiO3 were fabricated using pulsed laser deposition method. Compared to those hole‐doped manganites‐based junctions, much stronger rectifying characteristics were observed in the formed junctions. Sp…

The application of a static hydrostatic pressure drove an initial additional influx of solutes to the center of the constructs due to fluid advection. The advective transport has disappeared when homogeneous hydrostatic pressure in the whole construct was achieved, which was, for this case, 6 minutes after the applica…
