In the present paper, the origin of midrib in lenticular martensite is clarified by examining the similarity between midrib and thin plate martensite in detail and studying the stress-induced growth behavior of thin plate martensite at various temperatures. Although lenticular martensite, especially midrib, exhibits a…
The application of transistors based on poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid) (PEDOT:PSS) in chemical and biological sensing is reviewed. These devices offer enormous potential for facile processing of small, portable, and inexpensive sensors ideally suited for point-of-care analysis.…
The concentrations of hydroxyl groups located inside and on the surface oxide films of a commercially pure titanium, cp-Ti, a type 316L austenitic stainless steel, SS, and a cobalt-chromium-molybdenum alloy, Co-Cr-Mo, were evaluated using X-ray photoelectron spectroscopy, XPS, and a zinc-complex substitution technique…
Al2O3-cubic boron nitride (cBN) composites were prepared from Al2O3 and cBN powders by spark plasma sintering (SPS) at temperatures of 1200 to 1600°C for 600 s under a pressure of 100 MPa. Densification, phase transformation, microstructure and mechanical properties of the Al2O3-cBN composites were investigated. Fully…
With the simple dinuclear Zn–Nd complex [ZnNdL(H2O)(NO3)3] (1) (H2L = N,N′-bis(3-methoxysalicylidene)ethylene-1,2-diamine) as the precursor, tetranuclear [Zn2Nd2L2(4,4′-bpy)(NO3)6]·Et2O (2) and [Zn2Nd2L2(4,4′-bpe)]·2H2O (3) (4,4′-bpy = 4,4′-bipyridine, 4,4′-bpe = trans-bis(4-pyridyl)ethylene) complexes are formed: sui…
In this tutorial review, the underlying principles of vibrational pumping in surface enhanced Raman scattering (SERS) are summarized and explained within the framework of their historical development. Some state-of-the-art results in the field are also presented, with the aim of giving an overview on what has been est…
The effect of high temperature treatment of ordered mesoporous carbons (OMCs) under neutral atmosphere is studied for OMCs prepared by using different carbon precursors (furfuryl alcohol, sucrose, acenaphthene and mesophase pitch) and different ordered mesoporous silica (OMS) templates (MCM-48 and KIT-6). The OMS-temp…
A novel nonadecanuclear silver double cage was isolated, in which a square antiprism and a pentacapped pentagonal prism templated by a chloride ion share a tetragonal face to form a snowman-like cluster that is held together by bridging alkynyl groups and trifluoroacetates.
The hydrogenation of phenol to cyclohexanol under mild conditions (∼340 K) was achieved over Raney Ni catalyst in the aqueous phase. The adsorption–desorption properties of the reactants (phenol and H2) and the products (cyclohexanone and cyclohexanol) on the Raney Ni catalyst are different in the aqueous phase and th…
The investigations of sequential cyclic reduction and oxidation (redox) of solid oxide fuel cell (SOFC) Ni–yttria-stabilized zirconia (YSZ) anode substrates presented here are aimed at monitoring and understanding changes in critical physical and mechanical properties as a function of degree of oxidation at . The comm…
Nanotechnologies are already interacting with the environment. Scientists and engineers are manipulating matter at the nanoscale, and these nanoscale processes and products are being used by industry in commercially available products. These products are either applied directly to the environment or end up in the envi…
Nanostructured nickel hydroxides are galvanostatically deposited onto a stainless steel substrate by a plating bath of nickel sulfate, sodium acetate, and sodium sulfate at room temperature. The anodically deposited nickel hydroxide electrodes are highly porous and composed of interconnected nanoflakes about in thickn…
This article examines the feasibility of using multiwall carbon nanotubes (MWCNTs) as a fire retardant in silicone-based foams. MWCNTs were mechanically blended with polydimethylsiloxane reactants without any previous functionalisation treatment. The flammability of the materials was characterised as a function of the…
Degradation profiles induced by partial discharges and those induced by oxygen plasmas are compared for polyamide/mica nanocomposites. Both the resistances to partial discharges and to plasmas improve with an increase in nanofiller content. On the other hand, the partial discharge resistance is not improved if mum-siz…
Efficient post-functionalization of conductive polymer films was achieved by Cu(+)-catalyzed "click"-cycloaddition of novel poly(azidomethyl-EDOT) and various functionalized terminal alkynes under mild heterogeneous conditions with high conversion efficiencies.
Microporous titanosilicate Ti-MCM-68 (Ti-MSE) was successfully synthesized by post-synthetic isomorphous substitution of Ti for Al and proved to be a high-performance catalyst, in particular showing superior performance to TS-1, Ti-BEA, and Ti-MWW for phenol oxidation using H(2)O(2) as an oxidant.
The thermal conductivities of vinyl endblocked polymethylsiloxane reinforced with silicone nitride (Si 3 N 4 ) particles alone or in combination with silicone carbide whisker (SiC w ) were investigated in this article. The results indicate that the silicone rubber incorporating of 50 vol% hybrid Si 3 N 4 particles of…
Polyanline (PANI)–silica and poly(3,4-ethylenedioxythiophene) (PEDOT)–silica colloidal composite particles having a diameter of 200–300 nm were synthesized, then converted to intrinsically conducting polymer (ICP)-inks viasolvent exchange. These inks could be inkjet-printed on indium tin oxide-coated poly(ethylene ter…
Well-aligned rectangular-shaped nanodiamond fibers (NDFs) with a length-to-width ratio of over 1000 were formed on a large-scale via a self-assembly process by drying acid-treated nanodiamonds of a uniform size (∼4 nm) from an aqueous solution. Nanodiamond thin films (NDTFs), instead of NDFs, have also been prepared b…
Solid tumors have an acidic extracellular environment and an altered pH gradient across their cell compartments. Nanoparticles responsive to the pH gradients are promising for cancer drug delivery. Such pH-responsive nanoparticles consist of a corona and a core, one or both of which respond to the external pH to chang…
