The rheological properties of soft materials often exhibit surprisingly universal linear and nonlinear features. Here we show that these properties can be unified by considering the effect of the strain-rate amplitude on the structural relaxation of the material. We present a new form of oscillatory rheology, strain-r…
Aperiodic crystals are crystalline materials with atomic structures that lack translational symmetry. This book gives a comprehensive account of the superspace theory for the description of the crystal structures, and symmetries of incommensurately modulated crystals and composite crystals. It also gives a brief intro…
Single-molecule chemical reactions with individual single-walled carbon nanotubes were observed through near-infrared photoluminescence microscopy. The emission intensity within distinct submicrometer segments of single nanotubes changed in discrete steps after exposure to acid, base, or diazonium reactants. The steps…
The peculiar nature of electron scattering in graphene is among many exciting theoretical predictions for the physical properties of this material. To investigate electron scattering properties in a graphene plane, we have created a gate-tunable potential barrier within a single-layer graphene sheet. We report measure…
Abstract Single crystals of methylammonium tetrachlorocuprate (II) dihydrate were obtained by slow evaporation method at room temperature. The crystals were characterized through powder XRD, thermogravimetric (TG‐DTA), low temperature DSC studies and FTIR and far IR spectra. While the powder XRD confirms the crystalli…
Abstract Hyperbranched polymers constitute a unique class of branched macromolecules, where structural complexity is complemented by relative ease of synthesis. The increasing interest in the study of these materials is due to their distinctive properties, inherently tied to their complex molecular architecture, and i…
This paper reviews the analyses and the experimental results of Micro-reflector optical disc system. In Micro-reflector optical disc, data are recorded on multiple virtual planes in a monolithic holographic medium. We have demonstrated the possibility of huge capacity from our analyses of readout characteristics of th…
Spinel NiZnCo ferrite granular films 1.5 μm in thickness were prepared on glass substrates by the spray plating method at 90°C with a bias magnetic field of 300 Oe. The soft magnetic film exhibited large saturation magnetization of 270 kA/m and high resistivity of 127Ω cm. The coercivity and in‐plane anisotropy field…
The thermodynamic and electrical effects of residual carbon in glass–barium titanate composites were investigated. Thermodynamic arguments are made suggesting that new phases form through carbothermal reactions between carbon and titanate‐based dielectrics. Experimentally, it was shown that the reduced dielectric sepa…

Ashes produced by the combustion of two types of biomass waste one generated during the extraction of olive oil (olive pomace) and the other during rice-husking were used, without any prior treatment, to make insulating plates with fire-resistant properties by means of simple molding and curing methods. The plates, wi…
In this study, photoisomerizable polyacrylate containing spiropyran moieties was synthesized. By taking advantage of the photoinduced structural transformations of the spiropyran moieties, photoinduced microscopic ordering and eventually macroscopic patterns were formed in the polymer films consisting of spiropyran-co…
In this paper, we reported that optically active supramolecular assemblies of an achiral phthalocyanine derivative, silicon 2,3,9,10,16,17,23,24-octakis(octyloxy)-29 H,31 H -phthalocyanine dihydroxide ( Pc 1), could be easily achieved through the Langmuir and Langmuir−Schaefer (LS) technique. We have found that the LS…
Abstract A series of symmetrical and unsymmetrical azoalkanes were synthesized and their potential as a free‐radical source for rheology modification of polyolefins was investigated. The experimental results show that unsymmetrical azoalkanes, in particular N ‐cyclohexyl‐ N' ‐ tert ‐octyldiazene ( 13 ), can be success…
In this work, we report on the interdiffusion of Ge and Si in Ti 3 SiC 2 and Ti 3 GeC 2 , as well as that of Nb and Ti in Ti 2 AlC and Nb 2 AlC. The interdiffusion coefficient, D int , measured by analyzing the diffusion profiles of Si and Ge obtained when Ti 3 SiC 2 –Ti 3 GeC 2 diffusion couples are annealed in the 1…
Abstract The semiconducting compound TlGaSe 2 was grown by solid state reaction technique. The crystal structure of this material was confirmed by single‐crystal X‐ray diffraction. TlGaSe 2 crystallizes in the monoclinic system with space group C2/c (No. 15), Z = 16 and unit cell parameters a = 10.779(2) Å, b = 10.776…
Nano‐crystalline 8YSZ was synthesized by the glycine‐nitrate process in a muffle furnace using zirconyl nitrate and yttrium nitrate as sources of oxidants. The effect of changing the elemental stoichiometric coefficient over a wide range (0.756–1.605) on the product characteristics (crystallite size, percent unreacted…
The design and optimization of a vapor-phase analyte deposition method for limit of detection (LOD) studies on engineered surface-enhanced Raman scattering (SERS)-active substrates is presented. The vapor deposition method was designed to overcome current challenges in quantitative analysis of lithographically produce…
Tantalum oxynitride powder with a baddeleyite crystal structure was synthesized and densified by hot pressing in Ar and under high pressure using a belt‐type high‐pressure apparatus. The tantalum oxynitride powder could not be densified completely under hot‐pressing conditions at 1400°C. The use of high pressure resul…
Optical signal amplification by a homodyne detection scheme is proposed and experimentally demonstrated. We estimated that this scheme improved the signal-to-noise ratio of an 8-layer 3x read-speed Blu-ray Disc (BD) by more than 20 dB.
