The crystallization behaviors of binary even-even normal alkane (n-alkane) mixtures (n-C(18)H(38)/n-C(20)H(42), abbreviated as C(18)/C(20)) with different compositions, both in the bulk state and in nearly monodisperse microcapsules, have been investigated by the combination of differential scanning calorimetry and te…
Multifunctional carboxylic acids have been used as durable press finishing agents for cotton with sodium hypophosphite (NaH 2 PO 2 ) as the most effective catalyst. In our previous research, we found that cellulose cross-linking takes place when cotton fabric treated with a combination of maleic acid and NaH 2 PO 2 is…
Mesoporous polymer and carbon thin films are prepared by the organic-organic self-assembly of an oligomeric phenolic resin with an amphiphilic triblock copolymer template, Pluronic F127. The ratio of resin to template is selected such that a body-centered cubic (Im3m) mesostructure is formed in the bulk. However, well…
This work investigates plasmon-enhanced multiphoton scanning photoelectron emission microscopy (SPIM) of single gold nanorods under vacuum conditions. Striking differences in their photoemission properties are observed for nanorods deposited either on 2 nm thick Pt films or 10 nm thick indium tin oxide (ITO) films. On…
We report on the glass-forming abilities of the homologous series 1,2-diphenylcyclo-butene, pentene, hexene and heptene-a series that retains the cis-phenyl configuration characteristic of the well-studied glass former, o-terphenyl. We find that the glass-forming ability shows a sharp maximum for the six-membered ring…
A kinetic study of the growth of BaTiO 3 under hydrothermal conditions using layered titanate nanotubes as precursors has been performed at 110 and 200 °C. At the early stages of crystallization, irrespective of temperature, pseudocubic BaTiO 3 nucleates on the surfaces of the nanotubes. Growth subsequently proceeds b…
Lipocalin-type prostaglandin (PG) D synthase (L-PGDS) catalyzes the isomerization of PGH(2) to PGD(2) and is involved in the regulation of pain and of nonrapid eye movement sleep and the differentiation of male genital organs and adipocytes, etc. L-PGDS is secreted into various body fluids and binds various lipophilic…
The polarization induced at the LaAlO${}_{3}$/SrTiO${}_{3}$ interface has been explored by optical second harmonic generation (SHG) spectroscopy. Our data reveal that an orbital reconstruction of the SrTiO${}_{3}$ surface occurs when three epitaxial monolayers of LaAlO${}_{3}$ are deposited on top of it. The reconstru…
A biomimetic was designed for the construction of a new efficient peroxidase-like nano artificial enzyme with a heme-imidazole component complexed with gemini 12-2-12/SDS supramolecules. The presence of a simple surfactant mixture (SDS/gemini 12-2-12 at a particular concentration) provided an apoprotein-like hydrophob…
The calculated optical effective masses of electrons, both orthogonal and parallel to the tetragonal axis of the crystal, are reported as a function of carrier concentration in Nb-doped anatase. The calculation is based on the band structure, obtained by density functional theory in the generalized gradient approximat…
The shear mechanical compliance of the glass−rubber transition or softening zone of high molecular weight amorphous polymers typically increases from the glassy compliance of ∼10 −10 cm 2 /dyn up to the rubbery plateau of ∼10 −6 cm 2 /dyn. The contributions from the local segmental relaxation and the Rouse modes canno…
Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) cathodes are prepared on NiO-yttria-stabilized zirconia (YSZ)/YSZ composite substrates using pulsed laser deposition (PLD) and the screen-printing method. The cathode by PLD outperforms that by screen-printing, with an enhancement of over 150% in the maximum power, which can be attribut…
Noscapine, the tubulin-binding anticancer agent, when administered orally, requires high ED(50) (300-600 mg/kg), whereas intravenous administration (10 mg/kg) results in rapid elimination of the drug with a half-life of 0.39 h. Hence, the development of long-circulating injectable nanoparticles can be an interesting o…
The time dynamics of the photoexcited carriers and carrier-multiplication efficiencies in PbS quantum dots (QDs) are investigated. In particular, we report on the carrier dynamics, including carrier multiplication, as a function of QD size and compare them to the bulk value. We show that the intraband 1$P$\ensuremath{…
Abstract Ultrathin β‐MnOOH nanofibers can be produced on a large scale via a green‐chemical method using an aqueous solution of very dilute Mn(NO 3 ) 2 and aminoethanol at room temperature. High‐magnification electron microscopy demonstrates that the β‐MnOOH nanofibers are 3–5 nm thin and up to 1 micrometer long and t…
In this study, advanced control of crystallographic orientations and magnetic properties of self-assembled nanostructures via rational selections of substrates is demonstrated. We show that in the perovskite-spinel BiFeO(3)-CoFe(2)O(4) model system the crystal orientation of self-assembled CoFe(2)O(4) nanopillars can…
Tb-doped ceria materials have been synthesized by the coprecipitation method. Cobalt oxide (2 mol %) has been added in order to improve the sinterability and conductivity. XRD measurements suggest that a part of the cobalt is incorporated in the ceria lattice. Ce 1− x Tb x O 2−δ materials showed predominantly ionic co…
The thermal conductivity of individual single-crystalline Bi nanowires grown by the on-film formation of nanowires (ON-OFF) has been investigated. We observed that the thermal conductivity of single-crystalline Bi nanowires is highly anisotropic. Thermal conductivity of nanowires (diameter ∼100 nm) in the off-axis [10…
High-speed and high-resolution photography have been used to investigate the relationship between creation, expansion, and collapse of a vapor cavity induced by a 6 ns laser pulse and the subsequent nucleation of crystals. A thin layer of supersaturated aqueous solutions of (NH 4 ) 2 SO 4 and KMnO 4 was confined betwe…
We investigate the role of substrates on the collective excitations of graphene by using a first-principles implementation of the density response function within the random-phase approximation. Specifically, we consider graphene adsorbed on SiC(0001) and Al(111) as representative examples of a semiconducting and meta…
