Influence of sr doping on magnetic and magnetocaloric properties of Nd₀,₆Sr₀,₄MnO₃Where Mi and Mi+1 are magnetization values measured in a magnetic field H at temperature Ti and Ti+1, respectively. Figure 3(a) show the dependence of -ΔSm on temperature, -ΔSm(T), for different field variations at interval of 5 kOe. Clearly, at a specific temperature, -ΔSm increases with increasing ΔH from 5 kOe to 50 kOe. As expected from Eq (...

Fabrication of organic solar cell utilizing mixture of solution - Processable phthalocyanine and fullerene derivative with processing additive solventFigure 5(a) shows the absorption spectra at the Q band of the C6PcH2 and C6PcH2:PC70BM composite in solution and solid thin films. It indicated that the width of the Q band was changed by adding PC70BM and/or DIO processing additive solvent. Figure 5(b) shows the the Davydov splitting at the Q band or the width of Q band of the C6PcH2 and C6PcH2...

Magneto - Thermoelectric effects in cylindrical quantum wire under the influence of electromagnetic wave for electron-optical phonon scatteringConclusion In this paper, we have analytically investigated EC in cylindrical quantum wire. The electronoptical phonon interaction is taken into account at both low and high temperatures. We expose the analytical expression of the coefficient EC in CQWIP. The results have been evaluated in GaAs/Al:GaAs CQWIP to see the EC's dependence on electro...

Transfer of ²³⁸U and ²³²Th from soils to tea leaves on Luong My farm, Hoa Binh province, Viet NamResults showed that the 232Th combination in leaves varied from 12.70 to 18.30 Bq/kg dry, while 238U changed from 18.77 to 27.64 Bq/kg dry. The average activity of 238U in leaves is about 3-5 times higher than that of trucks and roots. Similar to 238U, 232Th is also concentrated mainly in leaves, in trucks and lower in roots. The average activit...

Original article high - Pressure melting curves of and phases of ironAs observed from Fig. 1, the melting curves of α and γ phases of iron are increasing functions of pressure. Our calculations of melting temperatures of iron are reasonably consistent with most of those of previous works but they overestimate the measurements performed by Komabayashi et al. [25]. The maximum difference between our predictions and...

Higgs and vector unparticle production via collision in the randall – sundrum modelHere, the cross-section increases fastly as 1.8 2 dU . Therefore, we evaluated it at dU 1.9. In Fig. 5 we charted the differential cross-section of the Higgs and vector unparticle production as a function of cos at 1.9 dU . The center-of-mass energy is chosen as s GeV 500 . The figure shows that the value of the differential cross-sec...

Preparation of ZnO nanoflowers for surface enhanced raman scattering applicationsFigure 5 shows the Raman spectra of 10-7 Mb measured on ZnO/Au nanorods and bare ZnO nanorods. As can be seen in the spectra, without gold layer, only a background noise was recorded. In contrast, clear Raman peaks of MB were observed when measured on ZnO/Au nanoflowers substrate. Characteristic peaks of MB can be detected clearly at 765, 1144, ...
