The temperature and magnetic field of the critical current density four selected pure C-doped ${\text{MgB}}_{2}$ samples have been investigated in detail flux pinning mechanism has analyzed. It was found that sintering substitution carbon can significantly modify mechanism. Below 30 K, reduced dependences force for all were to closely obey one scaling law, reflecting presence only dominant A $\ensuremath{\delta}{T}_{c}$ be mainly responsible while $\ensuremath{\delta}l$ becomes samples.
Random lasers (RLs), which possess peculiar advantages (e.g., emission and coherence tunable) over traditional with optical resonators, have witnessed rapid development in the past decades. However, it is still a challenge to tune lasing peak of an RL wide range. Here, temperature-dependent Förster resonance energy transfer (FRET) demonstrated pyrromethene 597 (PM597, “donor”) Nile blue (NB, “acceptor”) doped chiral liquid crystals. By changing temperature that drives crystal bandgap shift,...
具有白光发射性质且发光可调的超分子水凝胶在发光材料和荧光检测领域具有广泛的应用前景.采用双(2-氨基丙基醚)聚丙二醇(PPG-NH2)链穿线带有正电荷的6-乙二胺修饰β-环糊精构成准轮烷,进而与锂皂石作用构筑了超分子水凝胶,并通过流变、zeta电势和扫描电镜等手段对凝胶性质进行了表征.当将扭曲分子内电荷转移(TICT)型的有机染料分子硫黄素T(ThT)和碘化4-[4-(二甲基氨基)苯乙烯基]-1-甲基吡啶鎓(DASPI)引入到水凝胶中,这两种有机染料能够在凝胶相中发生荧光共振能量转移(FRET),从而产生包括白光在内的不同颜色的荧光发射.本研究为水基超分子发光软材料提供了一种新的构筑方法.
A fiber Fabry-Perot interferometer (FPI) based on a bubble-expanded microcavity is investigated in this paper. Due to the expanded bubble microcavity, FPI exhibits high strain sensitivity of 30.66 pm/με. To best our knowledge, such three ten times higher than that FPIs microcavities previously reported. The response with different shapes analyzed, and experimental results are consistent theoretical analysis.
The influences of connectivity and disorder on the critical current density Jc are discussed to clarify different mechanisms Jc(H) enhancement in magnetic field ranges. Excess Mg MgxB2+10 wt % SiC composites effectively improves connectivity, as evidenced by both resistivity properties Raman scattering. promising Mg1.15B2+10 is attributed high improved irreversibility field, Hirr, which agreement with fitting analysis. scattering measurements suggest a strengthened electron-E2g coupling...
We present a new scheme of high-efficiency one-dimensional (1D) atom localization via measurement upper state population or the probe absorption in four-level N-type atomic system. By applying two classical standing-wave fields, peak position and number, as well conditional probability, can be easily controlled by system parameters, sub-half-wavelength is also observed. More importantly, there 100% detecting probability subwavelength domain when corresponding conditions are satisfied. The...
A simple and green method for the synthesis of fluorescent silver nanocluster–nanoparticle complexes (AgNCs–AgNPs) is presented.
We report a systematic study of the effects polymer addition on lattice parameters, microstructure and superconducting properties MgB2. Polyvinyl alcohol [−C2H4O−]n (PVA) as typical was used an additive to It found that PVA additions have following features: (1) can very low oxygen (O) content or even none at all, has O (C:O = 2:1), which reduces impurities brought into MgB2 from doping, (2) decomposes temperature 400–650 °C, means reaction occurs in same range formation, providing highly...
We demonstrated the enhanced nonradiative resonant energy transfer (NRET) process by localized surface plasmon (LSP) in hybrid InGaN quantum well (QW) and CdSe/ZnS dot (QD) structures. The LSP wavelengths could be adjusted silver (Ag) nanoparticle (NP) arrays annealed from different thicknesses of Ag films. that are close to peak QD emission helped enhance NRET between QW QDs. Compared original absence NPs, LSP-enhanced rate was improved 6.9 times at wavelength 600 nm. calculated efficiency...
Firewalls are one of the essential components secure networks. However, configuring firewall rule tables for large networks with complex security requirements is a difficult and error prone task. A method representing table that allows comparison two developed, an algorithm determines if equivalent provided. (That set packets permitted by same.) How such can assist system administrators to correctly implement organisational policy discussed. The proposed approach implemented results...
Based on the formalism developed in another paper [Phys. Fluids 31, 3362 (1988)], three analytical results are obtained relating to (1) a WKB type of equation inhomogeneous plasma, (2) Raman process at (1/4) nc, and (3) two plasma decay processes nc. Interesting scaling found.
The effect of thermal annealing Ni∕AlxGa1−xN∕GaN structures on electric properties AlxGa1−xN∕GaN heterostructures has been studied by means temperature-dependent Hall measurements and deep level transient spectroscopy. It is found that the mobility two-dimensional electron gas (2DEG) decreases from 1530to986cm2∕Vs at room temperature (RT) after Al0.25Ga0.75N∕GaN heterostructure with a 10nm thick Ni cap layer 600°C. density 2DEG also reduced 2.0×1012cm−2 RT annealing, increasing between 100...
