Bu çalışmada, saf nikel oksit (NiO) ve Evropiyum (Eu) katkılı NiO nanoparçacıklar sol-jel yöntemi kullanılarak sentezlendi. Ni kaynağı olarak Nikel (II) asetat tetrahidrat Eu ise klorür kullanıldı. Sentezleme işlemi 80 ℃’de 3 saat sürede gerçekleştirildi. Sentezlenen 450 1 süreyle tavlandı. Nanoparçacıkları oluşturan bileşikler X-ışını kırınımı (XRD) analiz edildi. Nanoparçacıkların morfolojile...

For sensing systems that characterize the spectro-polarimetric radiance reaching the camera, the origin of the sensed phenomenology is a complex mixture of sources. While some of these sources do not contribute to the polarimetric signature, many do such as the downwelled sky polarization, the target and background pBRDF(polarimetric bi-directional reflectance distribution function), the upwell...

We examine the ability of the Expansionary Fiscal Contraction (EFC) hypothesis to explain the performance of of OECD economies during times of crisis. We ̄nd some limited evidence in its favour: if public consumption is reduced in response to a ̄scal crisis (as de ̄ned by a high level of debt), private consumption does seem to increase. However the size of the e®ect is smaller than that typicall...

We report on the non-destructive measurement of Young's modulus thin-film single crystal beta gallium oxide (beta-Ga2O3) out its nanoscale mechanical structures by measuring their fundamental mode resonance frequencies. From measurements, we extract in (100) plane, EY,(100) = 261.4+/-20.6 GPa, for beta-Ga2O3 nanoflakes synthesized low-pressure chemical vapor deposition (LPCVD), and [010] direct...
