The six-electron-donating ligand tribenzylidenemethandiide has been used to form a tantalum (group 5) mimic, ( 775 -cyclopentadienyl )( 77 -tribenzy lidenemethandiide )dimethyltantalum, of a group 4 bent metallocene. The material crystallizes with two molecules in the asymmetric unit with quite different packing arrangements, although the overall structures of the two are similar. The Cp and me...

Two-dimensional (2D) group-III-V honeycomb films have attracted significant interest for their potential application in fields of quantum computing and nanoelectronics. Searching for 2D III-V films with high structural stability and large-gap are crucial for the realizations of dissipationless transport edge states using quantum spin Hall (QSH) effect. Based on first-principles calculations, we...

An intentionally grown GaN film with laterally patterned Gaand N-face polarities is studied using in situ UV-photoelectron emission microscopy ~PEEM!. Before chemical vapor cleaning of the surface, the emission contrast between the Gaand N-face polarities regions was not significant. However, after cleaning the emission contrast between the different polarity regions was enhanced such that the ...

Symmetry-breaking in a quantum system often leads to complex emergent behavior. In bilayer graphene (BLG), an electric field applied perpendicular to the basal plane breaks the inversion symmetry of the lattice, opening a band gap at the charge neutrality point. In a quantizing magnetic field, electron interactions can cause spontaneous symmetry-breaking within the spin and valley degrees of fr...

Seismic Inversion methods have been routinely used for estimating attributes like P-impedance, Simpedance, density, ratio of P-wave and S-wave velocity and elastic impedances from seismic and well log data. These attributes help to understand lithology and fluid contents in the subsurface. The objective of this research is to use several standard seismic post-stack inversion methods for reservo...

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

In recent years, a number of extensive applications difference operators through sequence spaces have been developed. The most crucial application is being used in the study functional analysis, operator theory and matrix theory. this context, present article makes an attempt to provide survey on various unify them by introducing two m+ 1-th sequential band matrices. purpose work also extend de...

Biochemicals, such as chlorophyll (Chl) and nitrogen (N), are closely related to photosynthesis process of vegetation. Their accurate estimation is an important topic in remote sensing Previous studies mainly focused on Chl-N content inversion leaf canopy level, few cared about their 3D distributions, which was also indicator for the growth status vegetation (GSV). Hyperspectral LiDAR (HSL) a n...

generally, the measured secondary field data is inverted into resistivity using two principal models; the homogeneous half-space model and the layered half-space model. while the homogeneous half-space inversion uses single frequency data, the inversion is done individually for each of the frequencies used, the multi-layer 1d inversion is able to take the data of all frequencies available into ...
