It is shown using full-wave simulations that several of the conventional assumptions made for extracting permeability data from a microstrip permeameter are not justified. In particular, the proportionality between the measured effective permeability in the device and the true permeability of the film is not a constan…
Degenerate interface layers in epitaxial scandium-doped ZnO thin films, Lorenz, Michael, Schmidt, Christian, Benndorf, Gabriele, Böntgen, Tammo, Hochmuth, Holger, Böttcher, Rolf, Pöppl, Andreas, Spemann, Daniel, Grundmann, Marius
We study the properties of wavefunctions and the wavepacket dynamics in quasiperiodic tight-binding models in one, two, and three dimensions. The atoms in the one-dimensional quasiperiodic chains are coupled by weak and strong bonds aligned according to the Fibonacci sequence. The associated d-dimensional quasiperiodi…
Nowadays, biomaterials are produced from a wide range of polymers. Among them, biodegradable and biocompatible aliphatic polyesters occupy a key position. Their chemical structure can be easily modi ed, which allows the tailoring of important properties such as bioadherence, mechanical properties, and kinetics of biod…
In an alternative approach to achieving nanoparticle-based enhanced surface plasmon resonance (SPR), we present a simple protein seeding-based method for the synthesis of a protein integrated, surface active silver nanoplanar structure, where the protein is cocrystallized with silver. The growth kinetics of this integ…
This work is concerned with the lattice energy of periodic assemblies of mass and charge distributions of the form, exp (-αp(2)), where α is an adjustable positive variable and p(̱) is the vector from the lattice site or average position. The energy of interaction between two distributions is the density-weighted inte…
High electric fields, that are characteristic of sub-micron devices, produce highly energetic electrons, lack of equilibrium between electrons and phonons and high rates of heat generation. This regime can be described using an extended hydrodynamic model, which is formed by a set of conservation laws of hyperbolic-ty…
Abstract N ‐isopropylacrylamide (NIPAM) is photopolymerized in a range of phosphonium‐based ionic liquids (ILs). The curing behaviour of polymer‐IL solutions (linear pNIPAM) and ionogels (crosslinked pNIPAM) is studied using rheometry, DSC, and GPC. It is found that the IL influences the mechanical properties, the rat…
An experimental study was conducted to investigate the influence of ageing on the morphological, thermal and mechanical properties of virgin and two types of recycled (from technological and postconsumer wastes) modified polyolefin blends. Immiscible blends of virgin low-density polyethylene (LDPE) and polypropylene (…
While the induction of teratology by cadmium (Cd) on diatoms is already known, reversal kinetics are not well documented. This study aims to understand the viability of diatoms exhibiting teratological frustules and their reproduction capacities within a Cd-impacted population to predict their return to normal diatom…
We experimentally and numerically investigated rf oscillation induced by spin transfer torque in a current-perpendicular-to-plane giant magnetoresistance (GMR) device with full-Heusler Co2MnSi (CMS) layers. High output power (Prf) of 1 nW was experimentally achieved owing to the large GMR effect resulting from the hal…
A new family of Y(4)/M(2) and Y(5)/M heterobimetallic rare-earth-metal/d-block-transition-metal-polyhydride complexes has been synthesized. The reactions of the tetranuclear yttrium-octahydride complex [{Cp''Y(μ-H)(2)}(4)(thf)(4)] (Cp'' = C(5)Me(4)H, 1-C(5)Me(4)H) with one equivalent of Group-6-metal-pentahydride comp…
This work reports the preparation of magneto-electric GaFeO(3) by the sol-gel route and its characterization by x-ray diffraction, dc-magnetization, ac-susceptibility, low temperature and high field (57)Fe Mössbauer spectroscopy and dielectric constant measurements. The prepared samples are found to be single phase fr…
Abstract Waste rubber powder (WRP) was modified by microwave, sol–gel method, and both microwave and sol–gel method, respectively. The mechanical and dynamic mechanical properties of natural rubber (NR)/modified WRP composite were investigated. The influence of bis‐(3‐(triethoxysilyl)‐propyl)‐tetrasulfide (TESPT) cont…
A Z-shaped junction constructed by a few-nanometer-long armchair-edged boron nitride nanoribbon (ABNNR) sandwiched between two semi-infinite zigzag-edged BNNR electrodes with different hydrogen-passivated edge treatment is proposed, and its spin-dependent electronic transport is studied by ab initio calculations. It i…
The mechanochemical fabrication of the composites between carbon fibers (CFs) and nylon-6 (N6) was investigated using a milling process. By the milling, defected surfaces were generated on CFs to obtain the homogeneous length with preserving the cylindrical shape of CF. Fourier transform infrared spectra revealed that…
Abstract Folate‐functionalized quantum dots, gold/silver nanoparticles, and magnetic quantum dots have been synthesized and used as fluorescence, dark‐field, and dual‐imaging probes for the detection of cancer cells and tissues. A very efficient and generalized folate‐functionalization method has been developed for va…
BACKGROUND: Peptide amphiphiles (PAs) are a class of amphiphilic molecules able to self-assemble into nanomaterials that have shown efficient in vivo targeted delivery. Understanding the interactions of PAs with cells and the mechanisms of their internalization and intracellular trafficking is critical in their furthe…
The paper presents a harmonized description of the diffusion of solutes with repeated aromatic jumping units (JU) in entangled aliphatic polymers above their T g . It is shown that the trace diffusion coefficients, D, are scaled with the number of JU or equivalently with solute molecular mass, M, as M –1 M – K α /( T…
Abstract Surface‐enhanced Raman scattering (SERS) imaging is a powerful technique for studying biological systems both in vitro and in vivo . In SERS, Raman scattering from molecules located near the surface of either gold or silver nanoparticles is enhanced by 10 5 –10 8 . This review describes the basic enhancement…
