Recent rapid progress in nanotechnology has focused research and development efforts on new high performance materials. Organic-inorganic hybrid materials such as nylon-layered silicate nanocomposites have attracted special interest and various studies continue to be conducted on thermoplastic resins.In this study, we…
Plain and fretting fatigue properties of β type titanium alloy, Ti-29Nb-13Ta-4.6Zr, underwent various thermo-mechanical treatments were investigated in order to judge its potential for biomedical applications. Ti-29Nb-13Ta-4.6Zr aged directly at 723 K for 259.2 ks after cold rolling shows the greatest fatigue strength…
A functionalized monomer based on 3,4-propylenedioxythiophene, namely ProDOT-OH, was synthesized easily in a single step from commercially available starting materials and was successfully polymerized electrochemically resulting in the formation of an electroactive conjugated film on the working electrode. The presenc…
A nano fabrication process using caesium chloride in an island lithography scheme has been used to make wells in a silicon dioxide layer on silicon. Silver structures have been made in these wells using an electroless process that involves the reduction of silver ions and oxidation of silicon in the presence of fluori…
Semiconducting nanoparticles of indium and thallium oxides (In2O3 and Tl2O3) have been successfully synthesized in high yield (>95%) by microwave irradiation. The oxides are synthesized in a simple domestic microwave oven (DMO) by adding an aqueous ammonia solution to the aqueous solutions of indium chloride (InCl3) a…
Selecting thermoplastics for a wide industrial application (automotive, appliances, lawn and garden, power tools, etc.) strongly depends on the plastic material composition, part design, processing (molding and welding) conditions. The structure of used thermoplastics, mechanical properties and composition (reinforcem…
Introduction of a long alkoxy chain at an sp3 carbon of the ethylenedioxy bridge of EDOT induces a large increase of the band gap of the resulting polymer.
Pores arranged in a two-dimensional hexagonal structure inside spherical mesoporous silica particles help to prevent the thermal sintering of gold nanoparticles compared to straight pores in MCM-41.
The emission and excitation spectra of single crystals of doped with and were measured with the aim to determine the location of the lanthanide energy levels relative to the valence and conduction band of the host crystal. By combining energies known for charge transfer bands involving trivalent lanthanides with syste…
Porous iron whose long cylindrical pores are aligned in one direction has been fabricated by unidirectional solidification of the melt in a mixture gas of hydrogen (nitrogen) and argon. Both hydrogen and nitrogen saturated in the molten iron are rejected at the solid–liquid interface during the solidification due to t…
The purpose of this study was to evaluate the effects of the silane coupling agent amount on the flexural properties and hydrolytic durability on an experimental composite resin for understanding the optimum amount of silanation. A spherical filler was silanated with 7 different amounts of gamma-MPTS, 0, 0.17, 0.34, 0…
La-modified bismuth titanate ceramics with compositions of Bi4−xLaxTi3O12 (x = 0, 0.2, 0.5, 0.75) were fabricated using powders prepared by a hydrolysis method. It was found that the partial substitution of lanthanum for bismuth in the Bi4Ti3O12 lattice significantly influenced the crystallization behavior, IR charact…
The first three chiral dodecamanganese clusters that behave as single-molecule magnets are reported. All reveal natural optical activity, which is stronger for the 2-chloropropionate derivative than for either the (S)-6-methoxy-α-methyl-2-naphthaleneacetate or the (S)-2-phenylbutyric acetate compounds. For the cluster…
A new, thermally initiated hydrogermylation-based method for the synthesis and surface functionalization of air- and moisture-stable germanium quantum dots is reported.
We present the in situ formation of crystalline CdSe quantum dots on the surfaces of oxidized, ozonized single-walled carbon nanotubes, which is a rational synthetic route to the synthesis of complex hierarchical assemblies.
Custom-engineered functionally-specific properties leading to greatly enhanced design versatility have drawn designers to composites, but will make these materials-of-preference only if better ways can be found for producing better joints. The very micro- and macrostructure that gives rise to the unparalleled properti…
Photo-reversible Pb2+-complexation in a purely aqueous environment exhibiting a thermosensitive phase transition at a lower critical solution temperature was achieved using a synthetic copolymer composed of N-isopropyl acrylamide and spiropyran acrylate.
A conducting polymer shunt capable of providing overcharge protection for rechargeable lithium batteries via a reversible, internal, self-actuating mechanism is described. A microporous separator was impregnated with poly(3-butylthiophene), an electrochemically active polymer that becomes electronically conducting whe…
Thermally-initiated living radical graft polymerization of poly(ethylene glycol) methyl ether methacrylate (PEGMA) with ozone-pretreated fluorinated polyimide (FPI) via the reversible addition–fragmentation chain transfer (RAFT)–moderated process was carried out. The chemical composition and structure of the copolymer…
Monolayer protected nanoclusters are of current interest due to their ease of synthesis, high stability and possibility to precisely control their aspect ratio by preparation procedures, so that they can be tuned for a wide range of applications. Since these nanostructured metallic particles show fascinating size depe…
