We observed the reflectance spectra of three different nano-scale array structures of Au-coated silicon nanorods. The trends of the reflectance spectra indicate that the localized surface plasmon modes can be spatially controlled by manipulating geometric parameters, namely the lattice constants of the array. In addition, the experimental results were compared with 2D numerical simulations base...
In the current study, a magnetic inorganic–organic nanohybrid material (HPA/TPI-Fe3O4) was produced and used as an efficient, highly recyclable and eco-friendly catalyst for the one-pot and multicomponent synthesis of 3,4-dihydroquinoxalin-2-amine, diazepine-tetrazole and benzodiazepine-2-carboxamide derivatives with high yields and in a short range of time (20–35 min)...
Y2O3 thin films deposited on (001)-MgO substrate have been investigated by high-resolution transmission electron microscopy (HRTEM) and electron energy loss spectroscopy. Digital processing of the HRTEM images reveals the presence of grains with a crystallographic structure different from that of the rest of the film (Ia3). The spectrum imaging technique has been applied in vicinity of the Y2O3...
In this paper, the procedure of developing an unconstrained Genetic Algorithm code to solve mooring pattern optimization problems for floating structures is described. How to spread mooring lines around the offshore structures and tension level of these lines are the factors that have direct effect on response or offset of floating units which experience environmental conditions such as waves, ...
This paper addresses Paul Churchland’s (2007) attempt to identify colors with surface reflectance spectra. Of particular concern is Churchland’s novel method of approximating surface reflectance spectra. While those approximations are generated by objective means and yield a striking match with human phenomenological color space, they are not physically meaningful. The reason for this is that t...
the uses of non-steroidal anti-inflammatory drugs (nsaids) are limited by a variety of side effects. so research on preparing new analgesic agents is important. according to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. the final compounds 10a-10e and 15a-15d were prep...
Surface-enhanced Raman scattering (SERS) spectra were measured for monolayers of various amino acids: L-methionine (Met), L-cysteine (Cys), L-glycine (Gly), L-leucine (Leu), L-phenylalanine (Phe), and L-proline (Pro) and their homodipeptides (Met-Met, Cys-Cys, Gly-Gly, Leu-Leu, Phe-Phe, and Pro-Pro) deposited onto a colloidal gold surface. Orientation of amino acids and their homodipeptides, as...
For a computable structure M , the categoricity spectrum is the set of all Turing degrees capable of computing isomorphisms among arbitrary computable copies of M . If the spectrum has a least degree, this degree is called the degree of categoricity of M . In this paper we investigate spectra of categoricity for computable rigid structures. In particular, we give examples of rigid structures wi...
