molecular electronics growing, and prospects of single-molecule electronics improving, there is an increasing need to understand the interactions and electronic structure at interfaces between molecular and nonmolecular phases1-3. The level of activity in new materials for organic light-emitting diodes, organic field-effect transistors, and organic solar cells; optical or transport characteriza...

In the frame of a long-term experiment carried out in Central Italy, conventional and organic winter wheat cropping systems were compared in 2004 and 2005 to evaluate the effect of system management on wheat grain yield and quality. The organic system showed grain and straw yield about 50% lower than the conventional system. Organic grain samples resulted 20% lower in protein content and exhibi...

Fuzzy adaptive least-squares (FALS), a pattern recognition method recently developed in our laboratory for correlating structure with activity rating, was used to generate quantitative structure-activity relationship (QSAR) models on the carcinogenicity of organic compounds of several chemical classes. Using the predictive models obtained from the chemical class-based FALS QSAR approach, the ro...

Following to the recent development of the organic-templated growth of materials, new types of photonic hybrid composite materials have emerged whose structure and function are organized hierarchically. Ordered, periodic mesoscopic materials allow the construction of composites with many types of guest, such as organic molecules or polymers. These host–guest materials combine the high stability...

A novel metal-organic framework based on 1,3-bis-(imidazol-1-ylmeth-yl)benzene (1,3-bimb), [Cd(NO(3))(2)(C(14)H(14)N(4))(2)](n), has been synthesized hydro-thermally. The structure exhibits a two-dimensional metal-organic (4,4)-net composed of Cd(II) atoms and bimb ligands, and such layers are further joined through inter-layer C-H⋯O hydrogen bonds to generate a three-dimensional supra-molecula...
