Colloidal Quasi-one-dimensional Zinc-based Semiconductor Nanocrystals
Get PDFIn the recent decades, colloidal nanocrystals, which also termed as quantum dots, have witnessed an extraordinary boom on the new synthesised structures and improved performances in relation to their applications. This thesis focuses on developing facile synthesis strategies, new properties and applications of the emerging colloidal quasi-one-dimensional zinc-based semiconductor nanocrystals. The novel structures have shown interesting properties with relevance to diverse applications
Stimulated brillouin scattering and rayleigh cooperative process in 300 km optical transmission
No full textThe generation high-order Brillouin Stokes is experimentally demonstrated in 300 km all-Raman transmission with normal Raman pumps and without mirror reflection, and a longest ever fiber laser is implemented at the same time. The OSNRs of the two Brillouin Stokes after 300 kin are both higher than 29 dB. (C) 2007 Wiley Periodicals. Inc.Engineering, Electrical & ElectronicOpticsSCI(E)EI2ARTICLE122939-29414
Changes in Gross Primary Production in Response to Afforestation in the Hilly Loess Plateau of Northern Shaanxi, China
No full textAs a large-scale afforestation initiative, the Grain for Green (GFG) program was implemented for more than decade in the hilly Loess Plateau of Northern Shaanxi starting in 1999 and inevitably affected plant biomass production. This study evaluated the trend and magnitude of gross primary production (GPP) changes with VPM in the study area over 2000–2012 and quantitatively identified GFG’s contribution. The results indicate that the regional mean GPP was 529.6 to 854.7 g C m−2 yr−1, which significantly increased by 1.63% per year during the period. At the pixel level, 80% of the pixels presented an increasing trend in annual GPP, and in nearly half of the region, the increasing trend was statistically significant. Spatial analyses showed that the GPP increased more significantly in the gully areas of the middle north area, while no evident change trend was observed in the southern forestland areas. Statistical data from relevant yearbooks and interpreted data from high-resolution images show that the GFG program promoted vegetation restoration. Taking the increased area of forestland to indicate the achievements of GFG, we estimated, using regression analyses, that the afforestation contributed 40%–60% to the increased GPP in the region during 2000–2012. Overall, the ecosystem had a positive response to the Grain for Green (GFG) program in Northern Shaanxi

No full textProducts of Hankel and Toeplitz Operators on the Bergman Space
No full textAbstractWe consider the question for which square integrable analytic functions f and g on the unit disk the densely defined products TfTg are bounded on the Bergman space. We prove results analogous to those obtained by the second author [17] for such Toeplitz products on the Hardy space. We furthermore obtain similar results for Hankel products HfH*g, where f and g are square integrable on the unit disk, and for the mixed Haplitz products HfTg and TgH*f, where f and g are square integrable on the unit disk and g is analytic
