Mn-substituted 1D [Zn1−xMnxSe](DETA)0.5(DETA = diethylenetriamine, x 0−0.3) inorganic−organic hybrid nanobelts have been synthesized by a solvothermal reaction in mixed solvent media. Strong Mn2+ internal transition (4T1 → 6A1) emission peaks at 585 nm (2.12 eV) are detected room temperature photoluminescence (PL) spectra, and the highest intensity is obtained when nominal Mn content 0.15. Temperature- pressure-dependent photoluminescent properties as well electron paramagnetic resonance...
The evolution process of Ag plays a dominant role and presents an obvious effect on promoting the ordering transition FePt NPs.
Manipulation of internal strain by an external light beam called photoelastic effect has been firmly established in ZnO nanorods. The underlying mechanism this interesting phenomenon arises from the combination screening electric field and converse piezoelectric effect. We demonstrate that is more pronounced thinner nanorods due to a larger surface volume ratio. In addition giving good evidence for existence semiconductor nanorods, our finding also provides excellent possibility development...

Three aluminium alloy conductive wires, Al–0·16Sc (wt-%), Al–0·16Zr (wt-%) and Al–0·12Sc–0·04Zr were designed produced by continuous rheo-extrusion process. The influences of composition pouring temperature during cast process on the microstructure, mechanical properties wires studied.

Abstract Theory predicts Cu‐doped ZnO (ZnO:Cu) has p ‐conductivity; however, this only been demonstrated in a small number of experimental and mechanistic studies. In paper, ZnO:Cu films were grown situ with varying Cu content, prepared using radiofrequency atomic source–assisted molecular‐beam vapor deposition. The results indicate that dopant 2+ had n ‐type behavior. As the content increased, + was major However, excess resulted formation second phases 2 O Cu–Zn. Cu–Zn phase increased Zn...

In actual measurement, the vibration frequency of measuring object may change. order to improve accuracy parameter estimation and this paper introduced composition filter principle self-mixing interference system, used normalized LMS algorithm simulate experiment signal with variation. The simulation results show that when changes, weight coefficient is always in a small magnitude (10-3) dynamic change, which can quickly converge suitable value. filtering effect no different from single frequency.
Becasuse of the influnce coupling unit, generalized Hamiltonian theory is difficult to implement directly in a multi-machine power system. Firstly, model system after P.u. normalized was used. Considering premise mutual conductance, created new Lyapunov function based on and achieved pseudo-generalized system, as result addtion item problem due has been solved. Secondly, excitation controller nolinear designed. Finally through simulation analysis, proved better response curve faster speed model.
