We report first-principles density-functional pseudopotential calculations on the atomic structures, electronic properties, and band offsets of ${\mathrm{B}\mathrm{a}\mathrm{O}/\mathrm{B}\mathrm{a}\mathrm{T}\mathrm{i}\mathrm{O}}_{3}$ and ${\mathrm{S}\mathrm{r}\mathrm{O}/\mathrm{S}\mathrm{r}\mathrm{T}\mathrm{i}\mathrm{…
Based on the high-temperature organometallic route (Sun et al. Science 287, 1989 (2000)), we have synthesized powders containing CoPt_3 single crystals with mean diameters of 3.3(2) nm and 6.0(2) nm and small log-normal widths sigma=0.15(1). In the entire temperature range from 5 K to 400 K, the zero-field cooled susc…
The equivalence between quasi-unit-cell models and Penrose-tile models on the level of decorations is proved using inflation rules for Gummelt coverings with decorated decagons. Due to overlaps, Gummelt arrangement of decorated decagons gives rise to nine different (context-dependent) decagon decorations in the coveri…
Protein mechanosensitive channels (MS) are activated by tension transmitted through the lipid bilayer. We propose a theory of lateral stress relaxation in a bilayer lipid membrane exposed to external pressure pulse in the patch-clamp experimental setting. It is shown that transfer of lipid molecules into a strained re…
Open single-wall carbon nanohorns (SWNHs) were compressed repeatedly at 50 MPa to generate a nanocarbon material of high bulk density. TEM observations and Raman spectroscopy revealed a significant distortion in the structure of the compressed SWNHs. The obtained nanostructured disordered carbon exhibits a high methan…
Abstract High density nanoparticle arrays on surfaces have been created using a template‐assisted approach. Templates were produced by evaporating aluminum onto substrates and subsequently anodizing the aluminum to produce nanoporous alumina films. The resulting templates have a narrow distribution of pore sizes tunab…
A Fourier modal method for analysing crossed anisotropic gratings is presented without any restrictions on the permittivity and permeability tensors of the medium in the grating region and the angle between the two periodic directions. A skew Cartesian coordinate system with skew angles both in and out of the grating…

In this paper, the phonon system for a perfect silicon lattice is obtained by means of a model considering a phenomenological potential that includes both two- and three-body contributions. Phonon dispersions are discussed, and anharmonic contributions to the phonon Hamiltonian are evaluated. The model is compared wit…
A fast Q-tensor method, which can model the defect dynamics in a liquid crystal director field, is presented. Conceptually based on the Oseen-Frank approach, we have added temperature energy density terms in addition to the strain energy terms, and an improved normalization method for fast calculations. The method is…
(ABSTRACT) This study examined the effects of household fabric softeners on the thermal comfort and flammability of 100 % cotton and 100 % polyester fabrics after repeated laundering. Two fabric properties related to thermal comfort, water vapor transmission and air permeability, were examined. A 3 X 2 X 3 experimenta…

A Chinese-vaselike cage, depicted, is contained within the crystalline nanoporous [Ga2(VO)3K2(OH2)3(C2H4P2O6)4(H2O)13] structure, NCHU-3, and is thermally stable up to 550 °C. NCHU-3 exhibits a highly reversible lithium-ion-intercalation and de-intercalation cycle between +3 and +5 volts. Such cyclability is a key asp…

A reaction system consisting of terephthalic acid, NaOH, inorganic Mn(II) or Mn(III) salt, and salicylidene alkylimine resulted in dinuclear manganese complexes (salpn)(2)Mn(2)(mu-phth)(CH(3)OH)(2) (1, salpn = N,N'-1,3-propylene-bis(salicylideneiminato); phth = terephthalate dianion), (salen)(2)Mn(2)(mu-phth)(CH(3)OH)…
Abstract The theoretical thermopower of a two‐dimensional electron gas (2DEG) is studied in a clean AlGaN/GaN heterostructure of zincblende (ZB) and wurtzite (WZ) symmetry over the temperature range 0.1–10 K. The phonon drag thermopower ( S g ) due to 2DEG coupling with 3D longitudinal and transverse acoustic phonons…
Abstract The object of this study was the synthesis of thermoplastic elastomer compounds by direct copolyesterification of reactive oligomers of poly(ethylene terephthalate) (PET) and of poly(tetramethylene oxide) (PTMO). PET was glycolysed to synthesise hydroxytelechelic oligomers of PET. Commercially available hydro…

Abstract Aliphatic polyesters containing thioester linkages were enzymatically prepared by both the copolymerization of lactone with mercaptoalkanoic acid and by the transesterification of polyesters with mercaptoalkanoic acids. The enzymatic copolymerization of ε ‐caprolactone with 11‐mercaptoundecanoic acid (11MU) a…
