The built-in electric field in compositionally graded (1 − x )Ba(Zr 0.2 Ti 0.8 )O 3 – x (Ba 0.7 Ca 0.3 )TiO 3 (BZT– x BCT) thin films prepared by pulsed laser deposition.
Improvement of the catalytic performances in thiophene HDS on NiW sulfides catalysts supported on commercial Beta (NiW/HB) and hierarchical Beta (NiW/HB-M) were studied by mechanical mixture with γ-Al 2 O 3 (NiW/Al 2 O 3 ) or Na + -exchange of the zeolites.
Graphene nanoribbons (GNRs) were successfully produced by using a laser to transform the tubular structure of multiwalled carbon nanotubes (CNTs).
The amount of energy carried by γ-rays during the fission process is an important consideration when developing new reactor designs. Many studies of γ-ray energy and multiplicity, from a multitude of fissioning systems, were measured during the 1970s. However the data from such experiments largely underestimates the h…
This contribution is a relativistic theoretical study to characterize systematically the main electronic transitions in a series of hexarhenium chalcogenide [Re6(μ3-Q8)X6](4-) clusters with the aim of understanding: (i) the terminal ligand substitution effect, (ii) the substitution effect of the chalcogenide ion on th…
We have studied the relationship between the π-topology and the photo-excited high-spin states of π-conjugated spin systems, 9-anthracen-(3-phenyl-t-butylnitroxide) radical (1m) and 9-anthracen-(4-phenyl-t-butylnitroxide) radical (1p) systems, by time-resolved ESR and transient absorption spectroscopies. For the meta-…
Monolithic ordered mesoporous silica with various sizes and shapes were prepared in one-pot modified Stöber synthesis using pomelo peel and CTAB as dual templates, and applied as packing adsorbents for peptide enrichment.
The ZnO ellipsoids and spheres are fabricated via a facile sonochemical process. Dye-sensitized solar cells based on 1D/3D double layered ZnO photoanode are designed. The ZnO ellipsoids and spheres show superior light scattering ability in DSSCs.
Gallium/gold composite microspheres fixed on a silicon substrate were successfully fabricated and used as a SERS substrate to detect malachite green molecules.
This work presents a simple method for post-processing of washing away the impurities formed on the films of solution processed CuInS 2 thin films.
Mn 6.87 (OH) 3 (VO 4 ) 3.6 (V 2 O 7 ) 0.2 microtubes have been fabricated by a simple one-step hydrothermal procedure.
A heat-capacity increase near the liquid-amorphous (glass) transition temperature (1060 K) is caused by dynamical instability leading to the freezing of the 4-coordinated network.
Fused aromatic ring extension strongly enhances the acceptor strength.
Water-soluble multi-arm star-shaped brush-like block copolymers of (PEO- g -PAA)- b -PEO were synthesized and exploited as polymeric nanoreactors to structure-direct in situ fabrication of CdSe QD colloidal nanocrystal clusters.
The thermal characteristic of a new out-rotor fault-tolerant permanent-magnet (FTPM) motor is modeled and predicted in this paper.Flow characteristics and thermal characteristics of this FTPM motor are calculated by using computational fluid dynamics method.The key is that an equivalent model is developed to replace t…
An MFI zeolite nanosheet-pillared montmorillonite clay (MPC) with a uniform hierarchical structure was synthesized by a recrystallization method.
We synthesized monomeric liquid crystals, M6R8 and I6R8, and nanoparticles of TiO 2 , to form a nanocomposite, which was characterized by polarized optical microscopy (POM), DSC and structurally with both wide angle X-ray diffraction and by X-ray scattering using the planar geometry.
Herein, we report on the intriguing electrical transport properties of compressed AlAs. The relative permittivity and the resistances of both the grain and bulk boundaries vary abnormally at ∼10.9 GPa, accompanied by the cubic-hexagonal structural transition of AlAs. With further compression, the boundary effect becom…
A simple, coarse-grained model of chiral, helical filaments is used to study the polymorphism of fibrous aggregates. Three generic morphologies of the aggregates are observed: ribbons, in which the filaments are joined side-by-side, twisted, helicoidal fibrils, in which filaments entwine along each other and tubular f…
It is important to understand the interface and interaction between graphene layers and SiC surfaces as well as the interaction of key intermediate Si and C atoms with these surfaces and interfaces in epitaxial graphene growth on SiC substrates.
