Knowledge of geometrical and physico-chemical properties of the sugar-phosphate backbone substantially contributes to the comprehension of the structural dynamics, function and evolution of nucleic acids. We provide a side by side overview of structural biology/bioinformatics, quantum chemical and molecular mechanical…
High-aspect-ratio TiO(2) nanotube arrays formed by anodic oxidation have drawn extensive attention due to their easy fabrication and various excellent optical, electrical and biomedical properties. In contrast to conventional single-layer TiO(2) nanotubes prepared via constant-voltage anodization, we synthesize multil…
A visible-light responsive C, N and Ce co-doped TiO2 mesoporous membrane has been synthesized via a weakly alkaline sol–gel route using P123 template. The co-doping of C, N and Ce resulted in a lowered band gap of 2.14 eV which improved the photocatalytic activity in visible light. The Ce-dopant was found to strengthe…
A new family of linear structure Pt(II) (triphenylamine alkynyl) 2(triethyl-phosphine) (2-carboxy-2-cyanovinyl-X-alkynyl) (where X = thiophene (PT1), [2, 2′]-bi-thiophene (PT2) or 1,2-di(2-thienyl)ethylene) (PT3)) complexes have been synthesized and characterized. The introduction of thiophene π-bridges enhanced the e…
Development of Mg batteries relies heavily on the thermodynamics and kinetics of the magnesiation of cathode materials that favor the high mobility of Mg ions in the host lattice and energy densities at least comparable to Li ion batteries. In this paper, we performed Density Functional Theory studies to understand th…
We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \\sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The modification of the dispersio…
Abstract: The electron backscatter diffraction (EBSD) technique and EBSD-based orientation microscopy (ORM) are very powerful techniques for the comprehensive characterization of crystalline microstructures in the scanning electron microscope. ORM delivers accurate and quantitative data about the morphology and crysta…
A novel glutathione (GSH) photoelectrochemical biosensor was fabricated using the newly synthesized graphene-CdS (GR-CdS) nanocomposites. The GR-CdS nanocomposites were prepared by a fast, one-step, aqueous reaction. The as-prepared GR-CdS structure inherited the excellent electron transport of GR and facilitated the…
Highly improved negative bias illumination stress stability was achieved in a Zn–Sn–O field effect transistor after an ozone (O3) treatment. The untreated ZTO FET exhibited a huge negative threshold voltage shift of 4.2 V but the O3 treated device exhibited superior stability under NBIS conditions: the Vth value of th…
The combined use of soft carbon (PeC) as anodic material, and propylene carbonate (PC) as electrolyte solvent is a promising strategy for the realization of high performance lithium-ion capacitors (LIC). PeC electrodes display a capacity of around 80 mAhg −1 during cycling carried out at 5C, which can be maintained fo…
A novel Raney Fe@HZSM-5 Fischer–Tropsch synthesis catalyst was synthesized via a facile one-pot strategy using an FeAl alloy as the Fe precursor and as the Al source. Aside from cracking/isomerization of heavy hydrocarbons, HZSM-5 also stabilizes Hägg carbide, resulting in excellent selectivity to gasoline fraction an…
Due to the π-conjugation of the whole molecule along with the push–pull property of a newly designed conjugated donor–acceptor porphyrin, the solution processed solar cells using the blend of the porphyrin small molecule with PC71BM exhibit a promising performance with a power conversion efficiency of up to 4.02%.
Triazolophanes have recently surfaced as a new class of shape-persistent macrocycles that bind anions. Bearing only triazole- and phenyl-derived CH hydrogen bond donors, these receptors have shown extraordinary Cl(-) binding strengths (>10(6) M(-1), CH(2)Cl(2)). The attributes of the triazolophane that are responsible…
Monodisperse ultrathin SnO₂ nanorods on nitrogen-doped graphene were firstly synthesized by a facile one-step hydrothermal strategy. The uniformed composites with high nitrogen content and ultrathin SnO₂ nanorods of 2.5-4.0 nm in diameter and 10-15 nm in length show a high reversible specific capacity, superior rate c…
SnS2 hollow microspheres and SnS2 3D nanoflake-based hollow microspheres are successfully synthesized via a one-step hydrothermal process. From the experimental results, a mechanism based on bubble-templating, self-assembling and subsequent shell evolution was proposed. These hollow spheres were tested as anode materi…
In this study, we demonstrate that Cu2ZnSn(SxSe1−x)4 nanocrystals with a tunable bandgap could be synthesized by a “hot-injection” protocol. In this protocol, metal stearates dissolved in oleylamine were injected into a hot solution of anion precursors in 1-octadecene (ODE) at a given reaction temperature. ODE, which…
Photochemical degradation at 1 sun under AM1.5G illumination was performed on six conjugated polymers and five different electron acceptors. Additionally, the respective polymer:PC60BM and P3HT:electron acceptor blends were studied, and all degradations were resolved in terms of film thickness and absorbance. A fully…
A low cost, low-temperature processable, highly efficient nickel sulfide counter electrode is demonstrated. Using the tailored, preformed nickel sulfide nanoparticles and electrostatic self-assembly, a novel counter electrode was fabricated that exceeded the efficiency of a conventional Pt-based cell.
We report the nonvolatile memory characteristics of pentacene-based organic field-effect transistors (OFET) using polystyrenepara-substituted with π-conjugated oligofluorenes (P(St-Fl)n (n = 1–3)) as chargeable polymer electrets. Effects of fluorene conjugated length on the surface structure and memory characteristics…
