The monograph Tribology of Abrasive Machining Processes is written by highly esteemed experts in abrasive and grinding processes. The authors looked on these important, quality of high tech products determining processes from the view of tribological science which makes the book unique and most interesting both for ad…
Benthic diatom communities have been documented many times to exhibit a predictable pattern of migration entrained to diurnal and tidal cycles forming transient biofilms in the estuarine intertidal. The highly visible nature of these biofilms means that many anecdotal descriptions of this behaviour exist, yet much sti…
Nanoporous Materials -- An Overview (G Q Lu & X S Zhao) Advances in Mesoporous Materials Templated by Nonionic Block Copolymers (C Yu et al.) Zeolite/Mesoporous Molecular Sieve Composite Materials (D T On & S Kaliaguine) Chromium-Containing Ordered Nanoporous Materials (P Selvam) Surfactant-Templated Mesostructured Ma…
CaCu 3 Ti 4 O 12 (CCTO) was prepared by solid‐state reaction and identified by X‐ray diffractometry. The evolution of the microstructure was observed by scanning electron microscopy (SEM). It was found that discontinuous grain growth developed during sintering, and large abnormal grains played a very significant role…
We investigate a buckling instability by both small angle light scattering and atomic force microscopy, demonstrating that a tunable phase grating can be created with a mechanical instability. The instability is realized in a prestressed silicone sheet coated with a glassy polymer film. Compression of the sample resul…
There has been a growing interest and effort over the last few years in the development of novel food packaging concepts, which can play a proactive role regarding product preservation, shelf-life extension, and even improvement. Several strategies have been devised to exert a positive action over the packaged foodstu…
A chemical vapor deposition (CVD) process modified with vapor trapping method has been used to synthesize n -type ZnO nanowires with high carrier concentration without incorporating impurity dopants. With this method, a spatial variation of synthesis condition was created and the donors were directly introduced into t…
Transport and dielectric measurements have been performed in $\mathrm{Ca}{\mathrm{Cu}}_{3}{\mathrm{Ti}}_{4}{\mathrm{O}}_{12}$ ceramics. The bulk ac conductivity shows a power-law behavior at different temperatures, which is related to polaron relaxation. The temperature dependence of the bulk dc conductivity indicates…
Carbon nanotubes are promising for use in biomedical and pharmaceutical sciences. Therefore, it becomes imperative to know the basic biological properties of carbon nanotubes in vivo. We labeled the water-soluble hydroxylated carbon single-wall nanotubes with radioactive 125I atoms, and then the tracer was used to stu…
Light emission at the particle plasmon frequency is observed in optically excited spherical gold nanoparticles. We find a photoluminescence efficiency of ${10}^{\ensuremath{-}6}$, which is essentially independent of particle size and four orders of magnitude higher than the efficiencies determined from metal films. Ou…
Abstract We have investigated a wide variety of surfactants for their efficiency in dissolving isolated single‐walled carbon nanotubes (SWNTs) in water. In doing so, we have completely avoided the harsh chemical or mechanical conditions, such as acid or ultrasonic treatments, that are known to damage SWNTs. Bile salts…
We have characterized the vertical transport properties of epitaxial layered structures composed of Pr0.7Ca0.3MnO3(PCMO) sandwiched between SrRuO3(SRO) bottom electrode and several kinds of top electrodes such as SRO, Pt, Au, Ag, and Ti. Among the layered structures, Ti∕PCMO∕SRO is distinct due to a rectifying I–V cha…
The electromagnetic theory of diffraction and the Babinet principle are applied to the design of artificial metasurfaces and metamaterials. A new particle, the complementary split rings resonator, is proposed for the design of metasurfaces with high frequency selectivity and planar metamaterials with a negative dielec…
Single-walled carbon nanotube (SWNT)/poly(methyl methacrylate) (PMMA) nanocomposites were prepared via our coagulation method providing uniform dispersion of the nanotubes in the polymer matrix. Optical microscopy, Raman imaging, and SEM were employed to determine the dispersion of nanotube at different length scales.…
Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3–xLiNbO3 {[Lix(Na0.5K0.5)1−x]NbO3} (x=0.04–0.20) have been synthesized by an ordinary sintering technique. The materials with perovskite structure is orthorhombic phase at x⩽0.05 and becomes tetragonal phase at x⩾0.07, a phase K3Li2Nb5O15 with tetragonal tungsten br…
Molecular and cellular MR imaging is a rapidly growing field that aims to visualize targeted macromolecules or cells in living organisms. In order to provide a different signal intensity of the target, gadolinium-based MR contrast agents can be employed although they suffer from an inherent high threshold of detectabi…
In 1955, a phenomenological theory of ferromagnetism was well established and had been corroborated by a considerable amount of experimental data. However, there were problems in the phenomenological theory of the dynamics of the magnetization field. The Landau-Lifshitz equation for damping of the motion of the magnet…
We derive an exact representation of the exchange-correlation energy within density functional theory (DFT) which spawns a class of approximations leading to correct long-range asymptotic behavior. In what amounts to be the simplest approximation, we obtain an electronic structure theory that combines a new local corr…
We have found CueO from Escherichia coli to have a robust cuprous oxidase activity, severalfold higher than any homologue. These data suggest that a functional role for CueO in protecting against copper toxicity in vivo includes the removal of Cu(I).
When a ferromagnet is in proximity with an antiferromagnet, lateral length scales such as the respective magnetic domain sizes drastically affect the exchange bias. Bilayers of FeF2 and either Ni, Co or Fe are studied using SQUID and spatially resolved MOKE. When the antiferromagnetic domains are larger than or compar…
