Superhydrophobic pure silver film composed of flower-like microstructures built by interconnected silver nanoplates on a copper plate without any modification was prepared by a facile galvanic exchange reaction between the aqueous [Ag(NH3)2]OH and the copper plate, giving rise to a contact angle as high as 157 degrees…
Monodisperse CeO(2) nanocrystals and superlattice-like colloidal particles have been successfully synthesized in ethanol-water mixed solvent by adopting a one-pot approach using icosahedral (NH(4))(2)Ce(NO(3))(6) as precursor.
A warm/hot formability testing apparatus was designed and fabricated for this study. The forming limit curve (FLC) and springback characteristics of AZ31B Mg alloy sheets at elevated temperatures of up to 300°C were investigated. The forming limit increased rapidly with temperature up to 200°C, and increased slightly…
The solidification structure of the coating layer on hot-dip Zn-11%Al-3%Mg-0.2%Si-coated steel sheet was studied by means of metallographic examinations together with calculation of phase diagram based on Thermo-Calc. The solidification structure observed, which exhibited a combination of the Zn/Al/MgZn2 ternary eutec…
In this review, a new method for the preparation of metal-assembled complexes based on copper(II) acetate type dinuclear systems has been reported. A variety of coordination modes of carboxylato group were classified into ten types of groups including bis-, tris-, and tetrakis-bridging based on our complexes and discu…
A simple electrospinning method is developed to introduce signal transduction ability into molecularly imprinted nanofibers.
A “subtractive” bacteriophage display biopanning approach has been used to identify 12-mer peptides that are capable of binding selectively to, and inducing the precipitation of, titania but not silica. Unlike the conventional bacteriophage display procedure, this approach consists of two selection steps: i) removal o…
Large porphyrinoids with three Rh(CO)2 groups at their dipyrrin units shows two-step metal transposition through the macrocycle in solution and the equilibrium between the C3v-isomer and the Cs-isomer depends on the solvent polarity.
Ru-incorporated TaN (Ru–TaN) films were investigated as a Cu diffusion barrier material. Ru–TaN films were prepared by sequential deposition of Ru and TaN using plasma-enhanced atomic layer deposition (PEALD). The film composition was controlled by the number of Ru unit cycles. While the resistivity of Ru–TaN films wa…
A series of star-shaped non-C3-symmetrical mesogens containing one naphthalene chromophore at a defined position have been synthesised to study the influence of phase symmetry and nano-segregation on the order of the chromophores and their interactions in potential semiconducting materials. Structural investigations r…
In this paper, we describe a green chemical route for highly selective growth of Au tips onto Te nanowires (NWs). We carefully selected the pH values to vary the redox reaction potential between Au3+ and Te NWs, allowing control of nucleation and growth rates of Au nanoparticles (NPs). In the presence of 10 mM CTAB, w…
The complexity of transformer design demands reliable and rigorous solution methods. Survey of current research reveals the continued interest in application of advanced techniques for transformer design optimization. This paper summarizes some of the most important developments in this research area. The main purpose…
Dibenzyl Disulfide (DBDS) is one of several sulfur compounds known to cause copper corrosion in transformers under certain circumstances. Remedial processes such as adsorbents, absorbents, and oil change-out have been known to reduce the concentration of DBDS in the oil. However, if not destroyed or removed below seve…
Although block copolymer motifs have received considerable attention as supramolecular templates for inorganic nanoparticles, experimental observations of a nanostructured diblock copolymer containing inorganic nanoparticles-supported by theoretical trends predicted from a hybrid self-consistent field/density function…
The new homoditopic ligand H2LC2′ self-assembles with lanthanide ions (LnIII) to yield neutral bimetallic helicates of overall composition [Ln2(LC2′)3]; it is fitted with two hexakis(oxyethylene) chains to test their effects on the thermodynamic, photophysical and biochemical properties of these complexes, with partic…
Nano-conductive adhesives have been attracting more and more interest in microelectronic packaging field due to their unique electrical and mechanical properties compared to conventional conductive adhesives. There has been extensive research on nano-conductive adhesives which contain nano-fillers such as nano-particl…
X-ray diffraction (XRD) and Raman spectroscopy were used to investigate stress dependence on thickness in PbTiO3 (PTO) films grown by pulsed liquid injection metalorganic chemical vapor deposition on a LaAlO3 (001) substrate (LAO). Films on sapphire substrate (R plane) were used as the polycrystalline film reference.…
Single-crystalline KNbO(3) nanocubes with orthorhombic phase were prepared in a large scale by a simple one-step molten salt route without using any surfactant as template; the nanostructures exhibited high piezoelectric properties such as d(33)=105 pC/N and k(p)=0.34 as piezoelectric materials.
Abstract Compounds with moderate and large negative dielectric anisotropy (Δɛ) are very attractive liquid crystal (LC) for vertical alignment mode (VA). Materials with such properties can be achieved by lateral substitution of a polar group into a mesogenic molecule. We synthesized some new LC materials with a negativ…
A general strategy in terms of large-scale and shape-controlled synthesis was used to design highly ordered mesoporous carbon spheres with controlled size from 50 to 500 microm by an evaporation induced organic-organic self-assembly inside ethanol-in-oil emulsions.
