This paper concerns, the problem to assess 3-D distributions of magnetic induction in soft magnetic systems like machine cores of transformers or generators. Within bulk material, estimations of distributions are restricted to numerical methods like FEM, the application of sensors being hard. On the other hand, in lam…
Highly uniform and perfectly crystallized ZnGa <sub>2</sub> O <sub>4</sub> hollow NSs were successfully fabricated <italic>via</italic> carbon@Ga(OH)CO <sub>3</sub> @Zn(OH) <sub>2</sub> core–shell–shell nanostructures by a two step hydrothermal method.
A compact composite right/left-handed transmission-line (CRLH TL) stub resonator is presented. The bandpass frequency of the resonator and the adjacent transmission-zeros are determined by the negative order resonance modes of the stub line. We demonstrate that these resonance frequencies can be arbitrarily controlled…
Three aromatic poly(amides) ( <bold>PAs</bold> ) were prepared, one of them containing a dimethyldiphenylsilane unit from a new aromatic diamine monomer with a bulky pendant polar group.
A nanovalve system composed of a carrier based on mesoporous silica nanoparticles mechanized with a square planar Pd( <sc>ii</sc> )-templated pseudo-rotaxane was synthesized. This nanovalve system was responsive to a cyanide stimulus, which resulted in demetalation to concomitantly release both the macrocycles and the…
The damping capacity and mechanical properties of Mg-6Al-1Zn alloy after heat treatment were investigated. The damping characteristics of un-heat-treated, solution treated, and aged Mg-6Al-1Zn specimens were determined by measuring the damping ratio and the logarithmic decrement of free vibrations of a bending beam cl…
Herein we detail the synthesis and characterisation of a series of zirconium compounds featuring the bis(amido)silyl ligand [(i)Pr2Si(NDipp)2](2-) (Dipp = 2,6-diisopropylphenyl). The functionalisation of bis(amido)silyl zirconium halide complexes with a variety of nucleophiles, such as LiNMe2, LiBH4 and MeLi, was expl…
A newly emerged class of Janus polymer particles, so-called “hard-soft” ones, were produced using seeded dispersion polymerization (SDP) of 2-ethylhexyl methacrylate (EHMA) with polystyrene (PS) particles in the presence of <italic>n</italic> -paraffin droplets.
Atomic undercoordination shortens the interatomic bond, deepens the energy level, raises the local energy density and lowers the atomic cohesive energy of Na solid skins and clusters.
A delayed liquid–solid transition has been found in strongly segregated olefin multiblock copolymers, compared to that in weakly segregated systems.
On page 28, a fundamental study of the direct resistive heating of emulsion-templated graphene aerogels demonstrates reliable, fast, energy-efficient and uniform temperature control of the graphene framework. R. Menzel, M. S. P. Shaffer, and team's findings lay a framework that may be exploited in a wide range of nove…
Polymeric complexes exhibiting interesting suspension bridge type binding and dissimilarity in complex formation behavior of 8B group members were studied.
In this work, a novel nanoporous gold/silver oxide (NP Au/AgO) composite (NPAAC) was fabricated by a simple two-step partial dealloying–stripping process for supercapacitor applications.
Metal nanoparticles embedded in hollow materials are important due to their wide applications in catalysis. In this work, we disclosed a nontraditional synthetic pathway to prepare silica hollow nanospheres by hydrothermal treatment in the presence of compressed CO2. Especially, the silica hollow nanospheres with an o…
In nuclear power plants, fuel is subjected to a wide range of power and temperature transients during normal and abnormal conditions. The reactor setback and step-back power pattern, fast temperature profile occurred during Loss of Coolant Accident and decay power followed by shutdown of power plant are the typical tr…
A tetracarboxylic acid-appended calix[4]arene derivative <bold>1</bold> which were insoluble in water could form a supramolecular hydrogel upon addition of both amines and HCl.
This work was attempted in order to provide a new and well-established approach for the quantification of Fe(2+) sites in zeolites. The experimental procedure was based on carbon monoxide and nitrogen monoxide sorption in Fe-exchanged ZSM-5 zeolites with different pore hierarchies, which was followed by IR spectroscop…
This paper gives an overview of the development and prospect of nanotechnologies utilized in the solar cell applications. Even though it is not clearly pointed out, nanostructures indeed have been used in the fabrication of conventional solar cells for a long time. However, in those circumstances, only very limited be…
The catalytic performances of skeletal Cu prepared from Cu-Ti amorphous alloy heated at various temperatures were tested for the hydrogen generation from ammonia borane. The catalytic activity per surface area decreased with increasing heating temperatures of Cu-Ti amorphous alloy. The thermal treatment of Cu-Ti amorp…
On the basis of the evolutionary methodology for crystal structure prediction, the potential crystal structures of magnesium carbide with a chemical composition of Mg2C are explored. Except the known cubic phase (Fm3̅m), two novel tetragonal structures (P42/mnm and I41/Amd) and two novel hexagonal structures (P63/mmc…
