Many aspects of glial development are regulated by extracellular signals, including those from the extracellular matrix (ECM). Signals from the ECM are received by cell surface receptors, including the integrin family. Previously, we have shown that Drosophila integrins form adhesion complexes with Integrin-linked kin…
The polymer-supported transfer of chemical vapor deposition (CVD)-grown graphene provides large-area and high-quality graphene on a target substrate; however, the polymer and organic solvent residues left by the transfer process hinder the application of CVD-grown graphene in electronic and photonic devices. Here, we…

In this article we present a novel route to high quality GaAs thin films via a solution processing technique (aerosol assisted chemical vapor deposition) using a novel single source precursor [Me 2 GaAs(H) t Bu] 2 . The thin films, grown on inexpensive glass substrates, were polycrystalline in nature with a Ga to As r…
Inspired by model studies under ultrahigh vacuum (UHV) conditions, inverse monolithic gold/ceria catalysts are prepared using thermal decomposition of a cerium nitrate precursor on a nanoporous gold (npAu) substrate. Cerium oxide deposits throughout the porous gold material (pores and ligaments 30–40 nm) are formed. n…
N ‐Acetylneuraminic acid (sialic acid, Neu5Ac) has recently gained interest as a potential marker for a variety of pathophysiological processes, although no Raman study has been reported for this important biomolecule. In this paper, the vibrational properties of Neu5Ac were studied by means of Raman, surface‐enhanced…
The structural stabilities of the molecular chain sheets constituting the crystal structures of the cellulose allomorphs Iα, Iβ, II, and IIII were investigated by density functional theory (DFT) optimization of the isolated chain sheet models with finite dimensions. The DFT-optimized chain sheet models of the two nati…
In bulk applications, it is essential that graphene sheets disperse individually in solvents or matrices, and therefore, suitable functionalisation regimes are crucially important. Here, isolated, highly soluble, alkyl-grafted graphenes were synthesised by reacting exfoliated Na-reduced graphite intercalation compound…
Dendrimers are nanosized hyperbranched polymers synthesized through an iterative step-by-step process; their size and structure are perfectly controlled, and they are widely used for biomedical purposes. Previously, we showed that a phosphorous-based dendrimer capped with anionic AzaBisPhosphonate groups (so-called AB…
Enhancement of critical current densities by high-pressure sintering in (Sr,K)Fe2As2 PIT wires, Pyon, Sunseng, Tsuchiya, Yuji, Inoue, Hiroshi, Kajitani, Hideki, Koizumi, Norikiyo, Awaji, Satoshi, Watanabe, Kazuo, Tamegai, Tsuyoshi
AIMS: Morphological, biochemical and genotypic characterization of a halophilic bacterium isolated from hypersaline ponds located at Las Coloradas (Río Lagartos, Yucatán, Mexico). Characterization of polymer produced by this strain was also performed. METHODS AND RESULTS: Twenty strains were isolated from water sample…
A kinetically selective thiol–Michael addition “click” reaction was employed for facile and efficient synthesis of dendrimers as a first example of using solely a single chemistry without protection/deprotection reactions in dendrimer synthesis. First, a wide range of thiols and vinyls were assessed for their reaction…
Magnesium alloy is a potential biomedical implant because of its outstanding biodegradability and mechanical properties. But the poor corrosion resistance of AZ91 magnesium alloy in physiological solution limits its biomedical applications. In order to improve the corrosion resistance and biological performance of AZ9…
Synthetic replacement grafts for heart valves and small-diameter blood vessels such as coronary arteries have the potential to circumvent many of the limitations of currently available autologous grafting materials. Cell-free material incorporating biologically active compounds may guide the formation of fully autolog…
A major challenge in plasmonic hot spot fabrication is to efficiently increase the hot spot volumes on single metal nanoparticles to generate stronger signals in plasmon-enhanced applications. Here, the synthesis of designer nanoparticles, where plasmonic-active Au nanodots are selectively deposited onto the edge/tip…
Highly pure semiconducting single-walled carbon nanotubes (SWNTs), sorted by density-gradient ultracentrifugation, undergo self-assembly using depletion attraction forces into rafts along lithographically defined patterns of narrow pitch (100 or 200 nm). The arrays demonstrate high pattern fidelity and channel filling…
Serials of Mn doping by substituting Cd sites on Cu2CdSnSe4 are prepared by the melting method and the spark plasma sintering (SPS) technique to form Cu2Cd1-xMnxSnSe4. Our experimental and theoretical studies show that the moderate Mn doping by substituting Cd sites is an effective method to improve the thermoelectric…
Thick polycrystalline pure PbTiO3 films with nano size grains were synthesized for the first time by aerosol deposition. Annealed 7 μm thick films exhibit well-saturated ferroelectric hysteresis loops with a remanent polarization and coercive field of 35 μC/cm(2) and 94 kV/cm, respectively. A large-signal effective d3…
Abstract The mechanistic aspects of supramolecular ordering of synthetic β‐amino acid based peptides in different organic solvents and fuel oils are reported. The peptide Boc‐ cis ‐ACHC‐Aib‐Phe‐OMe (Boc= tert ‐butyloxycarbonyl, cis ‐ACHC= cis ‐2‐aminocyclohexanecarboxylic acid, Aib=α‐amino isobutyric acid, Phe=phenyla…
Carbon fiber-reinforced epoxy composites (CFEC) were fabricated infusing 0–0.40 wt% XD-grade carbon nanotube (XD-CNT) using the compression molding process under 16 kips. XD-CNTs were infused into Epon 862 resin using a mechanical stirrer followed by a high intensity ultrasonic liquid processor. The mixture was then p…
