A self-healing capability specifically targeted for sandwich composite laminates based on interfacial layers with built-in vascular networks is presented. The self-healing occurs at the facesheet–core interface through an additional interfacial layer to seal facesheet cracks and rebond facesheet–core regions. The effi…
Wann ist ein Acen stabil? Der multiradikalische Charakter von Graphen-Nanobändern unterschiedlicher Größe und Form wurde mit Multireferenzmethoden untersucht. Aus den erhaltenen quantitativen Informationen über die Zahl an effektiv ungepaarten Elektronen können spezifische Abschätzungen der chemischen Stabilität von G…
We measured the total AC loss in a 6/2 (i.e. 6 strands of 2 mm width) Roebel cable by incorporating a transport measurement method for Roebel cable into a total AC loss measurement system. The amplitude and frequency of the external magnetic field and applied transport current, and the field angle (the angle between t…
Symmetrical liquid crystal dimers bis{2-alkyl-(S)-(+)-2-(6-[4-4′-decyloxyphenylazo)-benzoyloxy]-2-naphthyl)propinate} have conveniently been designed, synthesised and their mesomorphic properties were investigated. These dimers possess two identical mesogenic units with each of them attached to the terminal end of a f…
A new iron selenide, K2FeGe3Se8, has been obtained by spontaneous crystallization. It adopts a new structure type in the noncentrosymmetric monoclinic space group P2(1). In the structure, FeSe4 and GeSe4 tetrahedra are connected alternately via corner-sharing to form one-dimensional (1D) (∞)(1)[FeGeSe6]6– chains along…
Abstract Nanomaterials gained great importance on account of their wide range of applications in many areas. Carbon nanotubes (CNTs) exhibit exceptional electrical, thermal, gas barrier, and tensile properties and can therefore be used for the development of a new generation of composite materials. Functionalized mult…
Control of the sidewall angle of diamond microstructures was achieved by varying the gas mixture, bias power and mask shape during inductively coupled plasma etching. Different etch mechanisms were responsible for the angle of the lower and upper part of the sidewall formed during diamond etching. These angles could t…
We have characterized the magnetoelectric (ME) properties of Pb(ZrTi)O 3 /LaNiO 3 /Ni (PZT/LNO/Ni) composites, which are fabricated using aerosol deposition.LNO acted as the bottom electrode for the PZT film and could effectively transfer the stress generated through the magnetostrictive effect of Ni into the piezoele…
We propose a method of generating entanglement using single photons and electron spins in the regime of resonance scattering. The technique involves matching the spontaneous emission rate of the spin dipole transition in bulk dielectric to the modified rate of spontaneous emission of the dipole coupled to the fundamen…
Th1−x U x O2 solid solutions were synthesized by solid-state reaction and pelletized using the spark plasma sintering (SPS) technique. Pellets with >90% theoretical density were easily obtained within 40 min of sintering without any additive. The thermal conductivity, Young's modulus, Debye temperature, Vickers hardne…
We report a magnetoelastic effect in doubly clamped ferromagnetic magnetostrictive Metglas resonators with electrically and magnetically reconfigurable frequency response. The field-induced resonance frequency shift is due to magnetostrictive strain, which is shown to have a strong dependence on uniaxial stress. Here,…
Abstract Polysiloxanes are commonly used in a myriad of applications, and the “click” nature of the thiol‐ene reaction is well suited for introducing alternative functionalities or for crosslinking these ubiquitous polymers. As such, understanding of the thiol‐ene reaction in the presence of silicones is valuable and…
The contribution of non-180° domain wall displacement to the frequency dependence of the longitudinal piezoelectric coefficient has been determined experimentally in lead zirconate titanate using time-resolved, in situ neutron diffraction. Under subcoercive electric fields of low frequencies, approximately 3% to 4% of…
LuFe1−xMnxO3 (x = 0, 0.05) ceramics with the orthorhombic distorted perovskite structure in space group Pbnm were synthesized using a solid-state reaction process. The dielectric, ferroelectric, and magnetic properties were investigated systematically. With Mn-substitution, the low temperature dielectric relaxation wa…
Abstract Amphiphilic polymer brushes grafted onto gold nanoparticles impart distinct solvent‐responsive behavior via the change to particle size and surface chemistry and, therefore, wide application prospects can be expected. Coarse‐grained simulations are performed for block and/or mixed polystyrene (PS)/poly(ethyle…
We report a current transport mechanism observed during electrochemical anodization of ion irradiated p-type silicon, in which a hole diffusion current is highly funneled along the gradient of modified doping profile towards the maximum ion induced defect density, dominating the total current flowing and hence the ano…
An efficient dissolution process was established for future reprocessing in which mixed-oxide (MOX) fuels with high plutonium contents and dissolver solution with high heavy-metal (HM) concentrations (more than 500 g dm−3) will be treated. This dissolution process involves short stroke shearing of fuels (∼10 mm in len…
Cross‐linked poly(orthocarbonate)s were prepared by condensation of the tetraethyl orthocarbonate with different length of aliphatic diols. The synthesized polymers have been characterized by Fourier‐transform infrared spectroscopy, solid‐state 13C cross‐polarization magic angle spinning (CPMAS) nuclear magnetic reson…
The FeCoNiB thin films with excellent soft magnetic properties were synthesized by radio frequency (RF) magnetron sputtering. Effects of RF noise suppression on the microstrip line using FeCoNiB films were investigated. It is found that FeCoNiB films with appropriate low Ni content exhibit excellent noise suppression…
A novel active fire protection approach, based on integrating a shape memory alloy, NiTi, with a steel structure, was proposed to satisfy the fire resistance requirements in structural design. To demonstrate the principles of this approach, a simple structure in the form of a simply supported steel beam was used. The…
