Design and packaging: Impact to consumer decision

In marketing theory and practice, product packaging is getting more important. Changes in the market give to packaging a multifunctional phenomenon which is more that core product protection. It represent company marketing strategy and it is competitive tool, which needs to be integrated into a marketing plan and adapt to product, brand price distribution and promotion strategy. A focus to this approach is getting to know customer behavior

Electron Charge Density Distribution from X-ray Diffraction Study of the M-Nitrophenol Compound in the Monoclinic Form

At room temperature, the m-Nitrophenol (m-NPH) appears in two polymorphicstructures: orthorhombic and monoclinic forms. In the present work, we shall focus on themonoclinic form of this compound which has a centrosymmetric structure with the spacegroup P21/n. The molecular dipole moment has been estimated experimentally. Highresolution single crystal diffraction experiment was performed at low temperature withMoKα radiation. The crystal structure was refined using the multipolar model of Hansen andCoppens (1978). The molecular electron charge density distribution is described accurately.The study reveals the nature of inter-molecular interactions including charge transfer andhydrogen bonds. In this crystal, hydrogen bonds of moderate strength occur between thehydroxyl group and the O atom in the nitro one

A Comparative X-ray Diffraction Study and Ab Initio Calculation on RU60358, a New Pyrethroid

The crystal structure of RU60358, C20H21NO3, has been determined using X-raydiffraction to establish the configuration and stereochemistry of the molecule around theC15-C16 triple bond. The compound crystallises in the orthorhombic space group P212121, a= 7.7575, b = 11.3182, c = 21.3529Ã¥, V = 1874.80Ã¥3 and Z = 4. The structure has beenrefined to a final R = 0.068 for the observed structure factors with I ≥ 3à (I). The refinedstructure was found to be significantly non planar. A comparative study, using the ab initiocalculations of the structure at B3LYP/6-31G** levels of theory, shows good geometricalagreement with the X-ray diffraction data. Standard deviations between the calculated andexperimental bond values have been shown to be 0.01 Ã¥ and 0.5° for bond angles.Vibrational wavenumbers were obtained from a normal mode analysis using the ab initiocalculations
