End-on oder side-on: Die Einelektronenreduktion des ansa-Zirconocenkomplexes mit einem Side-on-Distickstoffliganden ergibt das entsprechende Anion, in dem der Bindungsmodus des N2-Liganden zu end-on verändert ist. Die Oxidation des Anions stellt den neutralen Komplex wieder her, einhergehend mit einer Änderung der N2-…
Unidirectional current flow (diode-like behavior) is observed in Al/Nanostructured Porous Silicon/Al structures (Al/SP/Al) after applying a forming electric field (E) for a long time. We found that rectifying characteristics depend on the direction ofE. The forward direction coincides with the direction ofE. The diode…
Understanding the mechanism of enhanced luminescence of rare earth doped glasses in the presence of nanocrystallites and growth kineics is fundamentally important for optical devices. Tellurite nanoglasses of composition (80-x) TeO 2 − 5 Na 2 O − 15 MgO − (x) Eu 2 O 3 , over the concentration region of 0 to 2.5 mol% a…
Abstract The effects on the thermal, morphological, and crystallinity properties of the different loadings of magnesium oxide (MgO) blended with 10% rubbers [9:1 natural rubber (NR)/epoxidized NR] and metallocene linear low-density polyethylene (mLLDPE) in the presence of N,N-m-phenylenebismaleimide (HVA-2) compatibil…
Abstract A series of novel cyclic and V‐shaped cuprous clusters, (HNEt3)2 [Cu6(bmsapy)4] (1), [Cu8(banlny)4] (2) and [Cu6(ansny)4Cl] (CF3SO3) (3), were synthesized. Compounds (1) and (2) possess a similar cyclic metal structural arrangement, and the metallic arrangement of compound (2) is as in (1) with an insertion o…
Emerging intrinsically tunable film bulk acoustic wave(BAW) resonators allow the development of new generation reconfigurable and agile microwave circuits. In this paper, we demonstrate the enhancement of tunable performance of the high Q-factor BaxSr1−xTiO3 BAW – solidly mounted resonators (BAW–SMR) by varying Ba con…
Recently observed photoluminescence (PL) in ZnO, positioned at 3.324 eV and known to be related to Ge impurities, is investigated here by uniaxial stress and Zeeman spectroscopy measurements. The 3.324-eV PL line shifts but does not split under uniaxial stress both parallel and perpendicular to the $c$ axis, indicatin…
We report a unique approach to fabricating a large number of iron oxide nanowires from a Fe plate. This is realized with the aid of both oxidation (chemical reaction) and atomic migration (physical phenomenon). A polycrystalline Fe plate was prepared and its surface was oxidized in HNO3 solution. Then, the plate was b…
In this research the effect of purification of CdSe nanoparticles for application in quantum dots sensitized solar cells (QDSSC) photoanodes are studied. The CdSe nanoparticles are attached to the titanium dioxide surface using a linker based approached (CdSe nanoparticles disperse in toluene) and direct mode attachme…
Irigenin, an isoflavone (mol. formula = C18H16O8), was isolated from the plant Iris hookeriana using dichloromethane as solvent. The compound was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible spectroscopy measurements. Structural analysis of XRD data confirmed the ortho…
Complex oxide thin films and superlattices with the perovskite ABO3 structure have been found to possess multifunctional properties. Here, we present our discovery of antisite defects, La ions in Fe(Mn) sites (denoted as LaB), in a La0.7Sr0.3MnO3/La0.7Sr0.3FeO3 superlattice. The antisite defect was directly characteri…
Abstract Structurally ordered interfaces between ferromagnetic electrodes and graphene or graphite are of great interest for carbon spintronics, since they allow spin‐filtering due to k‐vector conservation. By solid phase epitaxy of amorphous/nanocrystalline CoFeB at elevated temperatures, the feasibility of fabricati…
One dimensional (1D) zinc oxide, ZnO nanostructures have shown promising results for usage in photodiode and optoelectronic device due to their high surface area. Faster and conventional method for synthesis ZnO nanorods has become an attention for researcher today. In this paper, ZnO nanorods have been successfully s…
The structure and physical properties of metallic magnetic conductor κ-(BDH-TTP)2FeBr4 (BDH-TTP: 2,5-bis(1,3-dithiolan-2-ylidene)-1,3,4,6-tetrathiapentalene) are investigated. It has a layered structure of BDH-TTP donor sheets extended along the \(ac\)-plane, which are sandwiched by FeBr4 anion sheets. The π electrons…
In this article, we describe a simple method to reversibly tune the wetting properties of vertically aligned carbon nanotube (CNT) arrays. Here, CNT arrays are defined as densely packed multi-walled carbon nanotubes oriented perpendicular to the growth substrate as a result of a growth process by the standard thermal…
Some selected acceptor-Be hydrocarbon complexes have been considered for evaluation of second hyperpolarizability at different DFT functional. All the complexes have been found thermally stable and there is a significant increase of second hyperpolarizability compared to the ligands. Second hyperpolarizability has bee…
Palladium (Pd) is a good candidate material for hydrogen gas sensing at room temperature due to its high affinity to hydrogen. Pd in the form of nanostructures has demonstrated better performance in its gas sensing property as compared to that in the form of bulk metal because of its large surface area to volume ratio…
The magnetic properties of axially confined, hydrogenated single-walled carbon nanotubes (SWCNTs) of the (n,0)-type with n=5-24 are systematically explored by density functional theory. Emphasis is placed on the relation between the ground-state magnetic moments of SWCNTs and zigzag graphene nanoribbons (ZGNRs). Compa…
This letter is the first to present a method to selectively hydrogenate the edges of sub-30-nm graphene nanoribbons (GNRs). After hydrogenation of the edges, the GNRs exhibit improved transport properties; carrier mobility increases by up to 50% at a carrier density of 5×1012cm-2at room temperature.
Three viologen derivatives with the ability to detect amines were synthesised. Upon interacting with amines, a rapid colour change caused by electron transfer and charge transfer between viologen derivatives and amines can be directly observed by naked eyes. With fluorine substituents, the detection sensitivity of the…
