In this review, we summarize recent progress in the application of synchrotron-based spectroscopic techniques for nucleic acid research that takes advantage of high-flux and high-brilliance electromagnetic radiation from synchrotron sources. The first section of the review focuses on the characterization of the struct…
Recent progress in the development of materials and devices for single-doped white devices is presented with a particular focus on the development of platinum complexes exhibiting excimer emission. White organic light emitting diodes (WOLEDs) are strong candidates for the next generation of solid-state lighting, yet m…
The present paper reports the investigations on sintering and hardness behavior of Fe-Al2O3 Metal Matrix Nanocomposites (MMNCs) prepared by Powder Metallurgy (P/M) route with varying concentration of Al2O3 (5–30 wt%). The MMNC specimens for the present investigations were synthesized by ball milling, followed by compa…
The influence of UV/ozone treatment on the property of polystyrene (PS) dielectric surface was investigated, and pentacene organic field-effect transistors (OFETs) based on the treated dielectric was fabricated. The dielectric and pentacene active layers were characterized by atomic force microscopy, X-ray photoelectr…
The synthesis of new conjugated building blocks, diselenolodiselenole (C4Se4) derivatives, is described for the first time. The structural and optoelectronic properties of C4Se4-derivatives are tuned by varying end-capping aromatic substituents. In cyclic voltammetry, all C4Se4-derivatives show two reversible oxidatio…
In this study, a small library of polyamidoamine (PAMAM) derivatives was prepared through the conjugation of its amines with various acrylates containing 5-21 carbon chain lengths at two different conjugation degrees, and the ability of the nano-sized PAMAM-based complexes to transfer the plasmid encoding interleukin-…
A recent study [C. Gainaru, R. Figuli, T. Hecksher, B. Jakobsen, J. C. Dyre, M. Wilhelm, and R. Böhmer, Phys. Rev. Lett. 112, 098301 (2014)] of two supercooled monohydroxy alcohols close to the glass-transition temperature showed that the Debye peak, thus far mainly observed in the electrical response, also has a mech…
Abstract The interaction of a highly dynamic poly(aryl acetylene) (poly‐1) with Li+, Na+, and Ag+ leads to macroscopically chiral supramolecular nanospheres, nanotubes, toroids, and gels. With Ag+, nanospheres with M helicity and tunable sizes are generated, which complement those obtained from the same polymer with d…
A new solid niobic acid phase, H2(H2O)Nb2O6, with fluorine (F) doping was crystallized using hydrothermal chemistry. F-doped H2(H2O)Nb2O6 octahedra could function as an efficient heterogeneous catalyst for the photodegradation of organic pollutants in water under UV light irradiation. The high photocatalytic activity…
A combined wet and dry cleaning process for GaN(0001) has been investigated with XPS and DFT-MD modeling to determine the molecular-level mechanisms for cleaning and the subsequent nucleation of gate oxide atomic layer deposition (ALD). In situ XPS studies show that for the wet sulfur treatment on GaN(0001), sulfur de…
Polyoxometalates (Ti0.75PW12O40, Ti-PTA)/TiO2 nanofiber composites were fabricated by a simple electrospinning technique and then high temperature calcination. In the structure, Ti-PTA, as an electron relay, can accept the photo-generated electrons from the conduction band of TiO2, which promote the separation of phot…
In the present work, organic/inorganic hybrid nanostructures comprised of polyaniline and vanadium oxide were synthesized via a simple hydrothermal technique. The polyaniline/vanadium oxide hybrid morphology was tailored from rods to spheres by controlling the relative concentration of the reactants. The synthesized c…
Despite their close structural similarity to nucleoside analogues such as the anti-HIV drugs AZT and d4T, 2',3'-dideoxyuridine (ddU) and 2',3'-dideoxy-2',3'-didehydrouridine (d4U) are entirely inactive against HIV in their nucleoside form. However, it has been shown that the corresponding triphosphates of these two nu…
Cost-effective production of lignocellulosic biofuel requires efficient breakdown of cell walls present in plant biomass to retrieve the wall polysaccharides for fermentation. In-depth knowledge of plant cell wall composition is therefore essential for improving the fuel production process. The precise spatial three-d…
Plasmonic nanoantennas exhibit various resonant modes with distinct properties. Upon resonant excitation, plasmonic gold nanoantennas can generate strong two-photon photoluminescence (TPPL). The TPPL from gold is broadband and depolarized, and may serve as an ideal local source for the investigation of antenna eigenmo…
Abstract The implementation of selective, energy efficient, direct alkane oxidation chemistry could lead to a new paradigm in materials and energy technologies for the 21st century that is environmentally and economically superior to current processes. Such processes would allow the vast reserves of natural gas to be…
Abstract We report mediated charge transfer across a nanoparticle that Faradaically interacts with its surrounding solution while impacting on an electrochemically inactive electrode. To this end, two different aspects of the process are elucidated and interconnected: The Faradaic reaction at the particle surface and…
The use of reversible covalent bonding in a four-component assembly incorporating chiral alcohols was recently reported to give a method for determining the enantiomeric excess of the alcohols via CD spectroscopy.
A bibliometric analysis based on the Science Citation Index Expanded was conducted to provide insights into the publication performance and research trend of quantitative structure-activity relationship (QSAR) and quantitative structure-property relationship (QSPR) from 1993 to 2012. The results show that the number o…
We demonstrate top-gate and bottom-gate structures of amorphous indium–gallium–zinc-oxide thin-film transistors and compare their device operation. A replica material stack is fabricated for depth profile characterization to correlate with device results. We mainly focus on the oxygen content at the top and bottom. Ke…
