Part of DC arcs may levitate from the insulators' surface to form air-gap arcs in the process of insulator's flashover, especially in the low air pressure. The air-gap arcs can cause the bridging between ribs (or sheds) of insulators easily, and the U–I characteristics of air-gap arcs and surface arcs are di…
We show that NMR stimulated-echo experiments provide detailed information about the jump dynamics of each of the ionic species in mixed mobile ion glasses. The potential of this technique is exploited to measure two-time correlation functions of the lithium and silver ionic hopping motions in Li${}_{x}$Ag${}_{1\ensure…
Abstract Gleich der Welt von Abbotts “Flächenland” ist auch die Welt von Graphen eine zweidimensionale. Und ebenso wie “Flächenland” ein “Märchen mit vielerlei Dimensionen” ist, ist auch Graphen viel mehr als nur ein flacher Kristall. Graphen hat eine Vielzahl ungewöhnlicher Eigenschaften, die oftmals einzigartig oder…
Malate synthase catalyzes the Claisen-like condensation of acetyl-coenzyme A (AcCoA) and glyoxylate in the glyoxylate shunt of the citric acid cycle. The Mycobacterium tuberculosis malate synthase G gene, glcB, was cloned, and the N-terminal His(6)-tagged 80 kDa protein was expressed in soluble form and purified by me…
Zinc oxide (ZnO), including a variety of metal-doped ZnO, as one kind of most important photoelectric materials, has been widely investigated and received enormous attention for a series of applications. In this work, we report a new finding which we call as lateral photovoltaic effect (LPE) in a nano Al-doped ZnO (ZA…
Nucleation of diamond is of great importance for its growth, and a detailed understanding of the nucleation process is, therefore, desired for many applications. The pretreatment of the substrate surface may impact the initial growth period. This study demonstrates the synthesis of diamond films by microwave plasma ch…
A facile, efficient, and unique self-assembly process for the preparation of the macroscopic, free-standing, Ag-reduced, graphene oxide (Ag-RGO) Janus films, which exhibit a unique asymmetry of their two surfaces with macroscopic dimensions, is presented. A novel strategy using an evaporation-induced, self-assembly (E…
UNLABELLED: Fish gelatin is a potential alternative to mammalian gelatin. However, poor gel strength and low melting point limit its applications. The study was aimed at improving these properties by adding coenhancers in the range obtained from response surface methodology (RSM) by using Box-Behnken design. Three dif…
In the present study, Fenton and sono-Fenton processes were applied to the oxidative decolorisation of synthetic textile wastewater including CI Reactive Orange 127 and polyvinyl alcohol. Process optimisation [pH, ferrous ion (Fe2+) and hydrogen peroxide (H2O2)], kinetic studies and their comparison were carried out f…
The low temperature, magnetic phase transition in LuFe2Ge2 is thought to be associated with itinerant magnetism. The effects of Y and Sc substitutions on the Lu site, as well as Ru and Co substitutions on the Fe site, on the low temperature magnetic phase transition of LuFe2Ge2 compound have been studied in single cry…
Energy production by using hydrogen gas as a feedstock is considered to be one of the keys to creating clean energy, with the proviso that the gas is generated in a sustainable way with no emissions. A simple, self-sustaining process generating hydrogen gas from methane using inexpensive stainless steel wire-mesh cata…
We study the low-energy edge states of bilayer graphene in a strong perpendicular magnetic field. Several possible simple boundary geometries related to zigzag edges are considered. Tight-binding calculations reveal three types of edge-state behaviors: weakly, strongly, and nondispersive edge states. These three behav…
Cubic and circular hexagonal mesoporous carbon phases in the confined environment of the pores of anodic alumina membranes (AAM) were obtained by organic-organic self-assembly of a preformed oligomeric resol precursor and the triblock copolymer templates Pluronic F127 or P123, respectively. Casting and solvent evapora…
Wunderbare (Ge)schichten: In ihren Nobel-Aufsätzen berichten die Preisträger von ihrem wechselvollen, aufregenden wissenschaftlichen Weg, der sie letztlich – unter anderem mithilfe von schlichtem Klebeband – zur Entdeckung des Graphens geführt hat, einer Monoschicht aus Kohlenstoff mit geradezu magischen Eigenschaften…
Despite the many attractive properties of conjugated polymers, their practical applications are often limited by the lack of a simple, scalable, and nondisruptive patterning method. Here, a direct, scalable, high-resolution patterning technique for conducting polymers is demonstrated that does not involve photoresists…
Domains of remnant polarization can be written into ferroelectrics with nanoscale precision using scanning probe nanolithography techniques such as piezoresponse force microscopy (PFM). Understanding the structural effects accompanying this process has been challenging due to the lack of appropriate structural charact…
Plasmonic coatings have been proposed as a robust method to suppress the scattering signature of conventional dielectric objects, typically by surrounding a given object of moderate size with an isotropic, homogeneous, dispersive material that has a low or negative permittivity. In contrast to transformation-based clo…
We have investigated the surface photochemical properties of Fe “doped” and (Fe,N) codoped homoepitaxial rutile TiO 2 (110) films grown by plasma-assisted molecular beam epitaxy. Fe does not incorporate as an electronic dopant in the rutile lattice but rather segregates to the film surface. However, codeposition of Fe…
The thermal boundary resistance between an individual carbon nanotube and a Au surface was measured using a microfabricated hot-film sensor. We used both closed and open-ended multi-walled carbon nanotubes and obtained thermal boundary resistance values of 0.947-1.22 × 10(7) K W(-1) and 1.43-1.76 × 10(7) K W(-1), resp…
Poly(1,4-naphthalenevinylene), prepared from a water-soluble precursor, was used to fabricate hybrid solar cells by blending with water-soluble CdTe nanocrystals (NCs) to act as the photoactive layer. In composites with CdTe NCs as the electron acceptors in a bulk heterojunction configuration, the devices exhibited a…
