We determined the three-dimensional crystal structure of the protein YML079wp, encoded by a hypothetical open reading frame from Saccharomyces cerevisiae to a resolution of 1.75 A. The protein has no close homologs and its molecular and cellular functions are unknown. The structure of the protein is a jelly-roll fold…
Phonon-induced spin relaxation rates in quantum dots are studied as function of in-plane and perpendicular magnetic fields, temperature and electric field, for different dot sizes. We consider Rashba and Dresselhaus spin-orbit mixing in diferent materials, and show how Zeeman sublevels can relax via piezoelectric and…
Vibration properties of Zn(1-x)Be(x)Se, a mixed II-VI semiconductor haracterized by a high contrast in elastic properties of its pure constituents, ZnSe and BeSe, are simulated by first-principles calculations of electronic structure, lattice relaxation and frozen phonons. The calculations within the local density app…
Ion beam implantation is attractive since it allows us to create very well-defined supersaturated concentration depth profiles in the near surface region. In this paper, thin layers of heterogeneous colloidal compound semiconductor nanocrystals will be discussed. We will focus on the synthesis of dense packed thin bur…
Abstract A new approach has been proposed and was shown to be a feasible method to produce nanosized polymer crystals of poly(acrylic acid). The new approach involves in situ polymerization of acrylic acid in the interlayers of a layered double hydroxides (LDHs) followed by exchange of the polymer anion for carbonate.…
We have demonstrated high-throughput synthesis and screening of a thin film photocatalyst library. Pulsed laser deposition enables us to grow the thin film photocatalyst epitaxially with atomically flat terraces and steps. A binary composition spread of [(SrTiO 3 ) 1− x (LaAlO 3 ) x ] (0 < x < 1) was fabricated by a c…
Abstract Colloidal dispersions of hybrid nanocomposite composed of gold nanoparticles (Au-NPs) and polypyrrole (PPy) were prepared by a sonochemical method, in which gold ion and pyrrole monomer in an aqueous solution were reduced and oxidized, respectively, by ultrasonic irradiation in the presence of poly(N-vinyl-2-…
The introduction of niobium into the FDU-1 structure has been studied. The evolution of the NbFDU-1 pore structure was deliberated using nitrogen adsorption at 77 K and X-ray diffraction. The influence of the niobium source on the structural properties and the incorporation of niobium species into the walls of FDU-1 m…
Abstract Combined a surface modification scheme with a neutralization reaction, accompanied with reduction procedure, highly dispersed gold nanowires within the pore channels of mesoporous silica thin films were prepared from organic–inorganic hybrid films modified with basic moieties.
In this work the first experimental observation of a peculiar behavior in the isotropic phase of liquid crystals by means of 2H NMR is reported. In particular, two five-ring banana-shaped mesogens, the 1,3-phenylenebis{4,4'-(11-undecenyloxy)benzoyloxy}benzoate (Pbis11BB) and its 4-chloro homologue (ClPbis11BB), select…
Wavelength-resolved femtosecond transient absorption spectroscopy is used to follow the electronic dynamics of single-walled carbon nanotubes in polymers following visible photoexcitation. Electron-hole (e-h) pairs give rise to sharp features in the transient spectra that decay in amplitude and exhibit rapid spectral…
Abstract Precise and uniform metallization of double-stranded DNA by the selective electroless plating method was investigated for the fabrication of nanowires. Cis-platin was bound to template DNA molecules and reduced to platinum which then catalyzed silver metal deposition. The DNA molecules combined with the plati…
[Structure: see text] Spiroconjugated TTF-type electron donors (13a-c) and TCNQ-type electron acceptors (10, 11) have been prepared from spiroquinone 9. Cyclic voltammetry reveals a relatively weak accepting ability for 10 and 11, and a strong electron-donor character for 13a-c. Whereas the spiroconjugation introduces…
A high-throughput screening technique has been developed and utilized in the discovery of a new n-type oxide possessing good thermoelectric properties. With this technique, 1000 samples can be prepared via a sol–gel method and their Seebeck coefficient ( S ) evaluated all within a day. For evaluation of S , a 'Seebeck…
An approach for high-throughput analysis of bulk and contact conductance of polymer layers is described and evaluated. The approach, based on s24-technique (simultaneous two- and four-point conductance measurements), was realized as a high-throughput method and applied for investigation of conductive polymers on an ar…
Due to the confusion in choosing coordinate systems, there occurred some misrepresentations/calculations of effective material properties of 0.67Pb(Mg1∕3Nb2∕3)O3–0.33PbTiO3 single crystals based on its single-domain data. This letter is to clarify these confusions by providing proper data set for each of the currently…
Indium–zinc-oxide (IZO) compositional libraries were deposited with dc magnetron sputtering onto glass substrates at 100 °C and analysed with high throughput, combinatorial techniques. The composition range from 4 to 95 at% In for Zn was explored. A peak in conductivity with σ > 3000 (Ω cm)−1 was observed at an indium…
Due to the limited number of cells available in endothelial cell (EC) seeding of small diameter vascular grafts, high seeding rate and ideal proliferation are normally required and can be achieved by optimizing the EC seeding and culture procedures. In this study, by using rotational seeding at 0.16 rpm for 12 h in an…
Herein, we describe the formation of silica structures on indium tin oxide (ITO) surfaces using poly-L-lysine (PLL) to template the condensation of silicic acid. Precisely controlled electrostatic fields were used to preposition PLL onto ITO surfaces. Subsequent polypeptide-mediated silicification resulted in the form…
A variety of machine learning algorithms, including hierarchical clustering, decision trees, k -nearest neighbours, support vector machines and bagging, were applied to construct models to predict the molecular weight of the polymers produced by a set of 96 homogeneous catalysts. The goal of the study was to develop m…
