The influence of finite ion temperature on plasma blob dynamics, Manz, P, Birkenmeier, G, Carralero, D, Fuchert, G, Müller, H W, Müller, S H, Scott, B D, Stroth, U, Ribeiro, T T, Wolfrum, E, the ASDEX Upgrade Team
The mechanical properties of Sheet Moulding Composite (SMC) have been analyzed by means of static and fatigue tests in tension. SMCs show a substantial in-plane anisotropy either in terms of stiffness or strength. Fatigue data were modeled adopting a fatigue model with two parameters, represented by the cyclic number…
Nanostructured Co 3 O 4 was synthesized through a gamma ( γ )-radiolysis technique using alcoholic (iso-propanol) salt solutions of cobalt ions with and without suspended graphene oxide (GO) nanoparticles, respectively. Formation of Co 3 O 4 accompanied with GO reduction takes place simultaneously ( in situ ) upon γ -…
A new term Volume Accessibility Factor (VAF), the product of micropore volume and acidity, correlates with ketone formation in modified montmorillonite.
The performance of polymer solar cells with a small molecule electrolyte interlayer (EDTA-N) was found to strongly depend on the external bias treatment and this behaviour could be ascribed to the ion motion in the electrolyte interlayer.
Centimetre-sized single crystals of high-quality CaBaCo2Fe2O7were synthesized by the optical floating zone technique. The metal-to-metal stoichiometry and oxygen content were confirmed by spectroscopy and thermal reduction experiments. The hexagonal symmetryP63mc(No. 186) well describes the powder X-ray and neutron di…
The article describes the view of the plasma surface engineering, assuming the role of non-thermal energy effects in the synthesis of materials and coatings deposition. In the following study it was underlined that the vapor excitation through the application of an electric field during coatings deposition gives new p…
Nanostructured copper thin films have been prepared using the pulsed laser deposition method. Optical absorption spectra of these films exhibit plasmonic absorption peaks around 619 nm, which suggests the formation of copper nanoparticles on their surfaces. Scanning electron micrographs of the films confirm the nanopa…
AIMS: Protoplast fusion between Aspergillus oryzae and Trichoderma harzianum and application of fusant in degradation of shellfish waste. METHODS AND RESULTS: The filamentous chitinolytic fungal strains A. oryzae NCIM 1272 and T. harzianum NCIM 1185 were selected as parents for protoplast fusion. Viable protoplasts we…
Abstract The particles of Mg–Zn–Gd icosahedral quasi‐crystal master alloy were added into the AZ31 alloy by the repeated plastic working (RPW) process in order to improve the mechanical properties of the AZ31 alloy at room temperature. The microstructure and tensile properties of composites were investigated by scanni…
In this work, we report the microfluidic preparation of monodisperse imidazolium-based poly(ionic liquid) (PIL) microgels with a controlled size and morphology, and show that the imidazolium units in the microgel network can be exploited as reactive sites to efficiently access desired functional materials by a simple…
In recent experiments at the HL-2A tokamak, dynamic features across the low–intermediate–high (L–I–H) confinement transition have been investigated in detail. Experimental evidence shows two types of opposite limit cycles (dubbed type-Y and type-J) between the radial electric field (Er) and turbulence evolution during…
Highly repeatable multilevel bipolar resistive switching in Ti/CeO x /Pt nonvolatile memory device has been demonstrated. X-ray diffraction studies of CeO 2 films reveal the formation of weak polycrystalline structure. The observed good memory performance, including stable cycling endurance and long data retention tim…
With the thickness of only a single atomic layer, graphene displays many interesting surface properties. A general observation is that wrinkles are formed on graphene oxide (GO) when it is dried in the presence of adsorbed inorganic nanoparticles. In this case, evaporation induced wrinkling is not an elastic deformati…
Motile filamentous cyanobacteria, such as Oscillatoria, Phormidium and Arthrospira, are ubiquitous in terrestrial and aquatic environments. As noted by Nägeli in 1860, many of them form complex three-dimensional or two-dimensional structures, such as biofilm, weed-like thalli, bundles of filaments and spirals, which w…
Mononuclear, acetato bridged dinuclear and phenoxo bridged trinuclear Zn( ii ) complexes have been synthesized. Their photophysical properties were characterized spectroscopically and with TDDFT and attributed to intra ligand (π → π*) charge transfer.
High-quality GaN films have been grown on nitrided LiGaO 2 substrates by pulsed laser deposition. The effect of nitridation on the properties of the GaN films and the growth mechanism of GaN films grown on nitrided LiGaO 2 substrates by pulsed laser deposition have also been systemically studied.
Abstract We synthesized hydrophilic and hydrophobic carbon nanoparticles (CNPs) by femtosecond laser (0.8 µm, 40 fs) irradiation of the water layer of an aerated benzene/water (B/W) bilayer solution. Focusing intense femtosecond laser pulses onto water creates a high density of reactive species such as hydroxyl radica…
The design and synthesis of ten novel coordination polymers was investigated. They have three structural types from 3D to 2D due to the synergistic effect of lanthanide contraction with diverse coordination modes and conformations of the ligand.
The objective of this research is to develop a novel, multimaterial additive manufacturing technique for fabricating laminated polymer nanocomposite structures that have characteristic length-scales in the tens of millimeters range. The three-dimensional (3D) printing technology presented in this paper combines the co…
