We report superconducting properties of single crystalline Ca${}_{10}$(Pt${}_{4\ensuremath{-}\ensuremath{\delta}}$As${}_{8}$)(Fe${}_{2\ensuremath{-}x}$Pt${}_{x}$As${}_{2}$)${}_{5}$ by x-ray diffraction, magnetization, resistivity, and magneto-optical imaging measurements. The magnetization measurements reveal a fish-t…
In recent years the field of tissue engineering, or regenerative medicine, has developed from the need to replace damaged and/or diseased tissues and organs by combining biomaterial scaffolds, biological signaling molecules, and cells.The regeneration of tissues may be achieved using either one of two principle approa…
Previously, an efficient D-xylose utilizing Pseudomonas putida S12 strain was obtained by introducing the D-xylose isomerase pathway from Escherichia coli, followed by evolutionary selection. In the present study, systemic changes associated with the evolved phenotype were identified by transcriptomics, enzyme activit…
In our continued efforts in the synthesis of ruthenium(II) polypyridine complexes as potential dyes for use in varied applications, such as the dye-sensitized solar cells (DSSCs), this work particularly describes the synthesis, absorption spectrum, redox behavior and luminescence properties of a new homoleptic rutheni…
The collective mechanical behavior of multilayer colloidal arrays of hollow silica nanoparticles (HSNP) is explored under spherical nanoindentation through a combination of experimental, numerical, and theoretical approaches. The effective indentation modulus E(ind) is found to decrease with an increasing number of la…
We report results on ultrafast photothermal release of DNA from gold nanoparticles. We show that dehybridization of oligonucleotide duplex anchored on a gold nanoparticle surface occurs during a single laser pulse, leading to the release of single-strand DNA in solution. Breaking of the Au-S bond anchoring the duplex…
Chemical vapor deposition on copper substrates is a primary technique for synthesis of high quality graphene films over large areas. While well-developed processes are in place for catalytic growth of graphene on bulk copper substrates, chemical vapor deposition of graphene on thin films could provide a means for simp…
We present the results of the first-principle calculations of the energy bands in graphene and their symmetry classification. The valence bands and four lowest conduction bands are classified according to their symmetry at points $\ensuremath{\Gamma}$ and $K$. Merging of the bands is interpreted in the framework of th…
Abstract The main methods for the design and preparation of single-site heterogeneous catalysts on inorganic oxide supports are described and reviewed. Catalytically active metal sites can be either introduced into the framework of porous materials via direct synthesis or added to a pre-existing support by post-synthe…
A visible-blind UV photodetector (PD) using a double heterojunction of n-ZnO/LaAlO3 (LAO)/p-Si was demonstrated. Inserted LAO layers exhibit electrical insulating properties and serve as blocking layers for photoexcited electrons from p-Si to n-ZnO, leading to an enhanced rectification ratio and a visible-blind UV det…
The compact thermodynamic approach to the systems containing calcium, magnesium, and carbonate species is referred to dissolution of dolomite, as an example of nonequilibrium ternary salt when introduced into aqueous media. The study of dolomite is based on all attainable physicochemical knowledge, involved in express…
Multifunctional hybrid: A dendritic platinum nanoparticle/lucigenin/reduced graphene oxide (RGO) hybrid with chemiluminescence (CL) activity was prepared for the first time by using lucigenin as a linker through simultaneous reduction of H(2) PtCl(4) and a lucigenin-functionalized graphene oxide composite by sodium bo…
Correlations among compositions, microstructures, and fluidity properties of three typical Asian coal ashes and their rapidly quenched slags were systematically investigated using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and multinuclear solid-state nuclear magnetic resonance (SS-NMR).…
The interpretation of scanning tunneling spectroscopy (STS) and scanning tunneling microscopy measurements of epitaxial graphene on lattice-mismatched substrates is a challenging problem, because of the spatial modulation in the electronic structure imposed by the formation of a moir\'e pattern. Here we describe the e…
In the recent work by Song et al. [Science 332, 1410 (2011)], the scanning tunneling spectroscopy experiment in the stoichiometric FeSe revealed evidence for nodal superconductivity and strong anisotropy. The nodal structure can be explained with the extended $s$-wave pairing structure with the mixture of the ${s}_{{x…
Natural rubber (NR) latex collected from the Hevea trees exists as a colloidal suspension (Verhaar, 1959). The amount of latex obtained on each tapping is about 300 mL. The tapping is usually done once every 2–3 days for 9 months each year. Usually, the collected latex is treated with formic acid to coagulate the susp…
Amorphous calcium carbonate (ACC) plays important roles in biomineralization, and the phosphoproteins extracted from biogenic stable ACC can induce and stabilize synthetic ACC in vitro. Here, mineralization of square-shaped ACC plates with micrometer-sized channels has been reported in the presence of the amphiphilic…
A polyhedral oligomeric silsesquioxane (POSS)-based supramolecular amphiphile is prepared from the host-guest inclusion complexation between a mono adamantane-functionalized POSS (AD-POSS) and a β-cyclodextrin oligomer (P(β-CD)). Assisted by the interface of H(2)O/toluene, the obtained supramolecular hybrids self-asse…
Abstract Single montmorillonite platelets have been successfully encapsulated by polymer through both a conventional and a reversible addition‐fragmentation chain transfer (RAFT) based emulsion polymerization. For both synthetic methods, the encapsulation process basically consisted of three steps: (i) adsorption of c…
In this work, a recently developed electron diffraction technique called diffraction scanning transmission electron microscopy (D-STEM) is coupled with precession electron microscopy to obtain quantitative local texture information in damascene copper interconnects (1.8 µm-70 nm in width) with a spatial resolution of…
