Abstract Dendritic BaTiO 3 ceramic powders (d‐ BT ) were prepared by hydrothermal method in order to improve the dielectric properties of d‐ BT /P( VDF ‐Tr FE ) composites, in which, KOH was used as the branch‐directing agent. The effect of hydrothermal time on the branch length of d‐ BT particle was mainly studied. T…
Abstract Molecular simulation has been successfully applied to sorption and hysteresis studies of various nanoporous materials, revealing underlying mechanisms that neither theoretical nor experimental approaches can achieve. In this work, the grand canonical Monte Carlo approach is used in a simplified wood-water sys…
(1), has shown an asymmetric current-voltage (I-V) curve in a conducting atomic force microscopy experiment on gold. Such molecular rectification has been ascribed to the asymmetric distribution of frontier molecular orbitals over its shuttlecock-shaped structure. Our nonequilibrium Green's function (NEGF) calculation…
Abstract One hundred and fifty GCN5-like acetyltransferases with amino acid-binding (ACT)-GCN5-related N-acetyltransferase (GNAT) domain organization have been identified in actinobacteria. The ACT domain is fused to the GNAT domain, conferring amino acid-induced allosteric regulation to these protein acetyltransferas…
In this work, wetting behavior of Ti–20Zr–20Cu–20Ni brazing filler on Ti–6Al–4V substrate was studied using sessile drop technique. Effects of the substrate surface roughness, R a of ~0.40 and 0.08 µm, and heating scheme on wetting and spreading of the filler metal were evaluated. The wetting mechanism was investigate…
The work in this paper presents the analyses of temperature-dependent simultaneous switching noise (SSN) and IR-Drop in multilayer graphene nanoribbon (MLGNR) power interconnects for 16[Formula: see text]nm ITRS technology node. A [Formula: see text] standard cell-based integrated circuit is designed to analyze the SS…
Motivation to study the ZnO channel for thin-film transistors (TFTs) is strong in light of its decent high mobility and large bandgap, enabling simultaneous coexistence of high on current and low off-state leakage. Nevertheless, the improvement in device performance for ZnO TFTs has not been fully exercised and even t…
In this work, AgNO 3 /CNTs composite is synthesized through a simple solution method. The morphology, electrochemical property, and lithium storage mechanism of AgNO 3 /CNTs are thoroughly investigated and compared with bare AgNO 3 . For AgNO 3, it can deliver an initial charge capacity of 552.3 mAh g –1 . After 100 c…
Technological activities to design, manufacture, and test new accelerating devices using different materials and methods is under way all over the world. The main goal of these studies is to increase the accelerating gradients and reduce the probability of radio-frequency (RF) breakdown. Indeed, it is still not clear…
A detailed account of the limiting factors of solvent-annealed bulk-heterojunction small-molecule organic solar cells is given. This account is based on the extensive characterisation of solar cell devices made from a library of five diketopyrolopyrole (DPP) donor dyes. Their chemical structure is designed in such a w…
Abstract Hybrid‐Halogenid‐Perowskit‐Solarzellen (PSCs) mit Wirkungsgraden über 22 % haben große Aufmerksamkeit auf sich gezogen. Trotz verstärkter Forschungen konnten die mit Perowskiten in PSCs zusammenhängenden grundlegenden Theorien aber noch nicht geklärt werden. In diesem Kurzaufsatz beurteilen wir die derzeitige…
The monoanionic bidentate ligand [(Ph 3 B)CH(3,5-(CH 3 ) 2 Pz) 2 )] − has been prepared from lithium bis(pyrazolyl)methanide and triphenylborane. This useful new ligand is closely related to the well-established bis(pyrazolyl)borate and bis(pyrazolyl)methane ligands but has key differences to both analogues as well. T…
Propagating spin waves excited by a micro-focused ultra-short pulse laser were investigated in Permalloy films with the thicknesses of 20, 50, and 100 nm by means of an all-optical space-and-time-resolved magneto-optical Kerr effect. Although various perpendicular standing spin-wave modes were excited, the propagating…
Abstract Three zirconium phosphate products A, B and C, made through different synthesis routes, were investigated for their europium and americium ion exchange properties utilizing radiotracers 152Eu3+ and 241Am3+. Aim of this investigation was to see how material properties change based on different synthesis, and h…
Abstract This study deals with the unprecedented reactivity of dinuclear non‐heme MnII–thiolate complexes with O2, which dependent on the protonation state of the initial MnII dimer selectively generates either a di‐μ‐oxo or μ‐oxo‐μ‐hydroxo MnIV complex. Both dimers have been characterized by different techniques incl…
Abstract Präzise Kontrolle über Morphologie und Funktion polymerer Nanostrukturen im Rahmen der Selbstorganisation stellt nach wie vor eine Herausforderung im Feld der Material‐ und biomedizinischen Wissenschaften dar, insbesondere wenn unabhängige Kontrolle über einzelne Partikeleigenschaften erwünscht ist. Hier wird…
