Student nations or simply nations are regional corporations of students at a university. Once widespread across Europe in medieval times, they are now largely restricted to the ancient universities of Sweden and Finland. The students, who were all born within the same region, usually spoke the same language, and expected to be ruled by their own familiar law. The most similar comparison in the Anglo-world to the nation system is in the collegiate system of older British universities or fraternities at American universities; however, both of these comparisons are imperfect. In Portugal and Brazil, there are fraternities called Repúblicas, but this has nothing to do with the natio original concept of nations . Wikipedia.

A discontinuous capillary coating device is disclosed. At least one capillary tube is filled with a coating material. At least one flexible member is disposed in the capillary tube and is immersed in the coating material. The flexible member extends to the exterior of the capillary tube, guiding and outputting the coating material. At least one coating substrate receives a liquid coating film from the coating material via the flexible member. At least one capillary tube holder holds the capillary tube, guiding movement of the capillary tube. At least one traversing mechanism drives the capillary tube holder or coating substrate to move.

Thin Solid Films | Year: 2011

Inorganic-solid-state electrolyte tantalum oxide thin films were deposited by reactive DC magnetron sputtering to improve the leakage and deterioration of traditional liquid electrolytes in electrochromic devices. O2 at 1-20 sccm flow rates was used to deposit the tantalum oxide films with various compositions and microstructures. The results indicate that the tantalum oxide thin films were amorphous, near-stoichiometric, porous with a loose fibrous structure, and highly transparent. The maximum charge capacity was obtained at an oxygen flow rate of 3 sccm and 50 W. The transmission change of the Ta 2O5 film deposited on a WO3/ITO/glass substrate between colored and bleached states at a wavelength of 550 nm was 56.7%. The all-solid-state electrochromic device was fabricated as a multilayer structure of glass/ITO/WO3/Ta2O5/NiOx/ITO/ glass. The optical transmittance difference of the device increased with increasing applied voltage. The maximum change was 66.5% at an applied voltage of ± 5 V. © 2011 Elsevier B.V. Source

Triazoloisoquinoline-based organic dyestuff was synthesized and used in the fabrication of dye-sensitized solar cells (DSSCs). After co-sensitization with ruthenium complex, triazoloisoquinoline-based organic dyestuff overcomes the deficiency of ruthenium dyestuff absorption in the blue part of the visible spectrum. The incident photon-to-electron conversion efficiency (IPCE) of cis-dithiocyanate-N,N′-bis-(4-carboxylate-4-tetrabutyl ammoniumcarboxylate-2,2′-bipyridine)ruthenium(II) (N719) at shorter wavelength regions (~350-500 nm) is 35 %. After addition of triazoloisoquinoline-based dyestuff for co-sensitization, the IPCE at 350-500 nm increased significantly. This can be attributed to the increased photocurrent of the cells, which improves the dye-sensitized photoelectric conversion efficiency. After optimization of the cells, an energy conversion efficiency of 8.83 % was achieved using an 12 + 4 μm TiO2 electrode, under simulated solar illumination (AM 1.5G). As a consequence, this low molecular weight organic dyestuff is a promising candidate as a co-adsorbent and co-sensitizer for highly efficient DSSCs. © 2013 Springer Science+Business Media New York.
