Stainless steel is gaining increasing use in construction because of its durability, favorable mechanical properties, and aesthetic appearance, with the austenitic grades being the most commonly used. Austenitic stainless steels have a high nickel content (8–11%), resulting in high initial material cost and significan…
Tuning of protein surface charge is a fundamental mechanism in biological systems. Protein charge is regulated in a physiological context by pH and interaction with counterions. We report on charge inversion and the related reentrant condensation in solutions of globular proteins with different multivalent metal catio…
In this study, Bi 2 WO 6 quantum dots (QDs) decorating reduced graphene oxide (RGO) sheets were produced by a facile one-step hydrothermal synthesis process, which converts the reactant precursors to Bi 2 WO 6 QDs and RGO simultaneously. The Bi 2 WO 6 QDs with a size of 3–5 nm anchored uniformly on the RGO sheets to f…
A new kind of ilmenite oxygen carrier was prepared by impregnating the raw ilmenite particles with K 2 CO 3, Na 2 CO 3, or Ca(NO 3 ) 2 . The cyclic reduction reactivity of the new oxygen carrier was investigated in a fluidized bed reactor. It has been found that the addition of foreign ions can significantly promote t…
Gold nanoparticles (AuNPs) have attracted increasing attention as catalysts for pollutant degradation because of their unique reactivity. Direct use of gold nanoparticles in water treatment faces prohibitive challenges from nanoparticle aggregation and post-treatment separation. To prevent nanoparticles from aggregati…
The transverse piezoelectric coefficient e31,f of Al1-xScxN thin films was investigated as a function of composition. It increased nearly 50% from x = 0 to x = 0.17. As the increase of the dielectric constant was only moderate, these films are very suitable for energy harvesting, giving a 60% higher transformation yie…
Here we provide a detailed X-ray photoelectron spectroscopy (XPS) study of the electrode/electrolyte interface of a graphite anode from commercial NMC/graphite cells by intense sputter depth profiling using a polyatomic ion gun. The uniqueness of this method lies in the approach using 13-step sputter depth profiling (…
11-Ring heterocyclic diimides were synthesized and found to be planar and to exhibit a slipped face-to-face π stacking. Variation of the substituents tunes the electronic structure and properties. In n-channel organic field-effect transistors, the new organic semiconductors have a high electron mobility. When they wer…
We present an ultrathin dual-band plasmonic waveguide and frequency splitter experimentally based on designer surface plasmon polaritons (DSPPs) of planar composite periodic gratings. In such planar plasmonic metamaterials, the electromagnetic wave can be tightly confined around an ultrathin metallic grating, and the…
Supramolecular polymers, whose building blocks are noncovalently connected, have attracted much attention over the last few decades. The noncovalent nature of these polymeric systems endows them with great potential for applications in the preparation of dynamic materials. Cucurbituril (CB)-based host-guest systems, w…
The strategic design of nanostructured materials, the properties of which could be controlled across different length scales and which, at the same time, could be used as building blocks for the construction of devices and functional systems into new technological platforms that are based on sustainable processes, is…
A facile synthetic route to dimethylsila[7]helicene by using a Lewis acid catalyzed double-cyclization reaction for construction of the twisted two phenanthrene moieties is described. Sila[7]helicene exhibited a high fluorescence quantum yield and a realatively large g value (dissymmetric factor) of circularly polariz…
PURPOSE: Taxanes are important chemotherapeutic agents with proven efficacy in human cancers, but their use is limited by resistance development. We report here the preclinical characteristics of cabazitaxel (XRP6258), a semisynthetic taxane developed to overcome taxane resistance. EXPERIMENTAL DESIGN: Cabazitaxel eff…
Ultrathin MoS2/N-graphene nanosheets with ≈4 nm thickness exhibit exceptional electrochemical performance. Extension of the defect sites and vacancies of the nanosheets results in the increase of capacity during cycling.
Recently, graphene oxide (GO) based nanocomposites have raised significant interests in many different areas, one of which being antibacterial agents where sliver nanoparticle (AgNPs) anchored GO (GO-Ag) has shown promising potential. However, to our best knowledge, factors affecting its antibacterial activity as well…
Recent progress in atmospheric plasmas has led to the creation of cold plasmas with ion temperature close to room temperature. This paper outlines recent progress in understanding of cold plasma physics as well as application of cold atmospheric plasma (CAP) in cancer therapy. Varieties of novel plasma diagnostic tech…
Preparation of potentially biodegradable poly(amide-ester-imide)s (PAEI)s with different amino acids was described. For the first time, the synthesis of diol N, N′-(1,3,5,7-tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6(1H,3H)-diyl)bis(4-hydroxybenzamide) (diol 4) was recounted. The diol 4 was supplied by Vitas-M Lab…
We propose a general theoretical solution by transforming to the loss problem of transformation media complex coordinates. In particular, this universal schematic has been demonstrated by two design examples of a loss compensated invisibility cloak and a loss compensated superlens with simple material parameters and s…
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…
