Abstract
A solar cell based on the n-MoS2/i-SiO2/p-Si heterojunction is fabricated. The device exhibits a high power-conversion efficiency of 4.5% due to the incorporation of a nano-scale SiO2 buffer into the MoS2/Si interface. The present device architectures are envisaged as potentially valuable candidates for high-performance photovoltaic devices.

Abstract
A #-shaped gold wires metamaterial is designed for surface enhanced Raman spectroscopy (SERS) and sensing. The tunability of surface plasmon resonance (SPR) excitations, hotspots distribution, localized field enhancement and sensitivity of the structure are investigated. In contrast to most metamaterial, the #-shaped structure exhibits two pronounced SPRs that are insensitive to the polarization of excitation light. Pure electromagnetic Raman enhancement factors of about 10(6) are achieved on the symmetrically distributed field hotspots. It is possible to break the usable wavelength range of conventional gold SERS substrates via higher order excitations of the #-shaped metamaterial. In addition, the sensitivity and the figure of merits are found to be comparable or even higher than those of conventional SERS substrates. All these factors together with the high reproducibility nature of metamaterial and its simple planer structure suggest that this structure is very promising for surface enhanced spectroscopy and sensing applications.

Abstract
Dual-band left-handed transmissions in the near infrared frequencies through the metal-dielectric-metal metamaterial perforated with an array of asymmetric cross holes are demonstrated. It is shown that the left-handed bands originate from the SPP-associated magnetic response excited by different polarized light and their frequencies can be tuned by the arm's length or width of the cross-gaps. The structures are further optimized at 1.064 microm laser light excitation for elucidating the mechanism and possible application in surface enhanced Raman spectroscopy in sandwiched architectures. This study provides valuable information for the design of compact optical devices with dual left-handed bands in a single structure and may also pave the way toward stable and reproducible substrate design for surface enhanced Raman spectroscopy.

Abstract
The purpose of our work was to find an efficient and reliable chemically assisted procedure for enucleation of porcine oocytes connected to the handmade cloning (HMC) technique without the potentially harmful chromatin staining and ultraviolet (UV) irradiation for cytoplast selection. After 41-42 h in vitro maturation, porcine oocytes were incubated with 0.4 microg/mL demecolcine for 45 min. Subsequently, the cumulus cells were removed and zonae pellucidae were partially digested. Oocytes with extrusion cones or oocytes only with polar body (PB) were subjected to oriented bisection. Less than half of the cytoplasm with the extrusion cone or adjacent to the PB was removed with a microblade. The remaining putative cytoplasts, containing the major part of the cytoplasm, were used as recipients for reconstruction with porcine fetal fibroblasts as nuclear donors. The overall efficiency achieved with chemically assisted enucleation was higher compared to oriented bisection without demecolcine incubation (90 +/- 3% vs. 81 +/- 4%, respectively; mean +/- absolute deviation [AD]). Reconstructed and activated embryos were cultured in vitro for 7 days. Fusion, cleavage and blastocyst rates were 87 +/- 7%, 97 +/- 6%, and 28 +/- 9%, respectively. These rates are at least as good as those achieved with normal HMC (81 +/- 4%, 87 +/- 8%, and 21 +/- 9%, respectively). For traditional, micromanipulator-based cloning, fusion and blastocyst rates were similar (81 +/- 10% and 21 +/- 6%, respectively), but the cleavage rate was lower (69 +/- 9%). In conclusion, chemically assisted handmade enucleation seems to be a simpler and potentially superior alternative to more conventional methods used for somatic cell nuclear transfer in pigs.

Abstract
We present a novel model of the effective thermal conductivity for carbon nanotube composites by incorporating the interface thermal resistance with an average polarization theory. The dependence of the effective thermal conductivity on nanotube length, diameter, concentration, and interface thermal resistance has been taken care of simultaneously in our treatment. The model predicts that the large length of the carbon nanotubes embedded plays a key role in the thermal conductivity enhancement, while the large interface thermal resistance across the nanotube-matrix interface causes a significant degradation. Interestingly, the model predicts that the nanotube diameter has a very small effect on the thermal conductivity enhancement of the nanotube composites. In addition, the model predicts that the thermal conductivity enhancement of nanotube composites increases rapidly with decreasing the thermal conductivity of the matrix and increases with increasing the thermal conductivity of the carbon nanotube. Predictions from the novel model are in excellent agreement with the experimentally observed values of the effective thermal conductivity of carbon nanotube nanofluids which the classical models have not been able to explain.

Abstract
The genetic mechanism underlying panicle number per plant (PN), spikelet number per panicle (SNP) and its related traits in rice was analysed using 292 F13 RILs from the cross of Lemont/Teqing and a complete linkage map with 272 molecular markers. The RILs showed tremendous transgressive segregation for all traits studied. The weak negative correlation between PN and SNP was observed. Fifty-one QTLs and 45 epistatic QTL pairs affecting these traits were identified, collectively explaining over 60% of the total variation of individual traits. Almost all SNP-QTLs were attributable to one or more of its contributing components. Branching number traits had greater contributions to SNP than length traits, in which the first had twice as many QTLs mapped in the same or near regions with SNP as the latter. Only two PN-QTLs were mapped in the near regions with those of related traits of SNP, suggesting a reasonable recombination between PN and SNP would be available by marker-assisted selection (MAS). Some major QTLs including QPn4 for panicle number, QPbn3a, QPbn3b and QPbl4 for panicle branching and length would be of great value in MAS. It was discussed that a new high-yielding panicle type was resulted from reasonably deploying for QTLs of panicle traits by MAS.

Abstract
Agrobacterium-mediated transformation of two-line genic male sterile Indica rice variety Pei'ai 64S was conducted using a cloned gene, Xa21, as the foreign gene and mature embryo calli as the recipients. A total of 46 transgenic plants had been obtained. The PCR analysis and Southern blotting showed the integration of Xa21 gene into the genome the transgenic plants. Results of inoculation with philippine race 6 of Xanthomonas oryzae pv. oryzae indicated that most of transgenic plants obtained high resistance to rice bacterial blight disease (Xoo). Analyses of T1 plants of the tested transgenic lines showed that integrated Xa21 gene could be steadily inherited and segregated in a 3:1 ratio.
