An air-stable star-shaped CoIICoIII3 complex with only one paramagnetic Co(II) ion in the D3 coordination environment has been synthesized from a chiral Schiff base ligand. Magnetic studies revealed that this exhibits slow magnetic relaxation absence of an applied dc field, which is main characteristics single-molecule magnets (SMMs). The barrier as high 109 K, quite large among transition-metal ion-based SMMs. represents first example zero-field SMM behavior mononuclear six...
Considering the energy consumption of crushed zone caused by blasting, dissipation characteristics were investigated through theoretical calculation and a plug-in for reduction was made. As result, an improved CDEM method suitable studying blast-induced crack propagation proposed. The then used to numerically simulate under three different in-situ stress conditions: uniaxial stress, biaxial equal stresses unequal stresses. It found that conditions had significant effects on distribution...
A pair of enantiopure star-shaped FeIII4 clusters were constructed from simple chiral ligands. AC field frequency dependence and a hysteresis loop, which are very important features SMMs, observed. Circular dichroism (CD) spectra demonstrated that the chirality was successfully transferred ligand to coordination environment Fe3+ ions.
In this paper, analytical solutions for Rayleigh wave in a transversely isotropic piezoelectric semiconductor (PSC) substrate with covering layer of different type doping are obtained. The PN junction (called also the depletion layer), which is created by diffusion and drifting due to layer, can be considered as an electrically gradient between substrate. Making use state transfer equation method, matrix vector derived mathematically. Based on numerical calculations, we investigate physical...
In this paper, a theoretical model of the propagation shear horizontal wave in piezoelectric semiconductor semi-infinite medium is established using optimized spectral method. First, basic equations are derived with consideration biased electric fields. Then, considering medium, two equivalent mathematical models established. first model, Schottky junction theoretically treated as an electrically imperfect interface, and interface characteristic length utilized to describe effect junction....
This paper theoretically investigates the influence of homo- and hetero-junctions on propagation characteristics radially propagated cylindrical surface acoustic waves in a piezoelectric semiconductor semi-infinite medium. First, basic equations medium are mathematically derived. Then, based these transfer matrix method, two equivalent mathematical models established concerning this Based interface effect theory, or hetero-junction is treated as two-dimensional electrically imperfect first...
