A good trend between the present calculated and available theoretical size dependent Young's modulus of different NWs is found, which supports the DNA NWs mechanical strength. We have extended our view to predict the behavior of the DNA NWs and see their resemblance to the behavior of either metallic or semiconducting nature of NWs. We have also demonstrated the variation in Young's modulus of the DNA NWs with the variation of relaxed material property of DNA NWs. This study extrapolates key factors in modelling DNA NWs for the electronic device applications.

A red colorant, which occurs on the outer surfaces of the ceramic pieces excavated from archaeological finding sites Čepin-Ovčara and Kneževi Vinogradi-Osnovna škola and in earth piece from Aljmaš-Podunavlje locality was analyzed. Using the UV-Vis FORS and Raman spectroscopy, red colorant is found to be red ochre. Raman spectrum of red ceramic colorant agrees with the spectrum of the colorant from the earth piece, leading to the conclusion that the Neolithic culture living in today Slavonija and Baranja region used the same colorants for decorating their ceramics as other nearby Neolithic cultures of Pannonian Basin. Black colorations are found to be made of soot.

It is observed from the theoretical investigation that GNR has highly length and width dependent thermal conductivities due to difference in the in/out-plane phonon mode in the phonon dispersion curve (PDC). The calculations show that thermal conduction of graphene nanoribbon increases with increasing edge roughness of graphene nanoribbons. Our findings are helpful for understanding and engineering of the thermal conductivity of graphene nanoribbons in potential electronic devices.
The efficiency of ten differently colored modified box traps for collecting tabanids was studied ... more The efficiency of ten differently colored modified box traps for collecting tabanids was studied in the Monjoroš Forest in eastern Croatia. A total of 5,436 specimens belonging to 16 species of tabanids grouped into six genera were collected. The genus Tabanus was the most represented with 98% of all collected tabanids. Tabanus bromius comprised 90% of tabanids collected, and was the most abundant species collected in all box traps. The majority of tabanids (74%) were collected from black, brown, bordeaux, red, and blue traps (dark group), whereas 26% were collected from green, light violet, white, orange, and yellow traps (light group). The black modified trap was the most successful and collected 20% of all collected tabanids, whereas the yellow trap was the least effective with 1%. The number of collected specimens of species T. bromius differed significantly between the dark and light group of traps. Traps with lower reflectance from green color collected 77% of T. bromius. The ...

Of all the photocatalytic materials TiO2 has been proved as the most useful one, with the most efficient photoactivity, the highest stability and the lowest cost. Moreover, it is safe for humans and the environment. The development of new types of photocatalytic cells is driven by the need for clean and sustainable energy. In this respect best doped materials are considered as a promising route for departing from the traditional photocatalytic cells. The physical insight provided by computational modeling may help develop improved photocatalytic devices. To this end it is important to obtain an accurate description of the electronic structure and phonon dynamics, including the fundamental gaps and level ali...

From the calculated electronic band structure and density of states we concluded that the doping induces significant changes in the band structure of TiO 2 , highlighting B-and Pt-doped TiO 2 as the best candidates for photocatalytic materials for visible light absorption. On the other hand, N-doped TiO 2 appears to be active only for the photoreduction processes, although N doping introduces midstates into the band gap. Only N-doped TiO 2 proved to have stable phonon dispersions and showed interesting band doubling. Ó 2013 Elsevier Masson SAS. All rights reserved.
