in this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. the benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (ch3coo)2cu.h2o individually as cu sources. al...

B Bader Theory for charge analysis 77 Bibliography 89 Introduction The wide eeort of the past decade to understand physical properties of the semiconductor heterojunctions has provided many fundamental and applica-tive results 1, 2]. The experience acquired on simple systems like isovalent common anion heterojunctions, e.g. GaAs/AlAs, has been successfully extended to heterovalent systems and a...

The measurement of long-range distances remains a challenge in solid-state NMR structure determination of biological macromolecules. In 2D and 3D correlation spectra of uniformly (13)C-labeled biomolecules, inter-residue, inter-segmental, and intermolecular (13)C-(13)C cross peaks that provide important long-range distance constraints for three-dimensional structures often overlap with short-ra...

Extended X-ray Absorption Fine Structure (EXAFS) has been one of the few structural probes available for crystalline, non-crystalline and even highly disordered specimens. However, the data analysis involves a patchy and tinkering process, including back-and-forth fitting and filtering, leading to ambiguous answers sometimes. Here we try to resolve this long standing problem, to extract the int...

Bacterial crystalline cellulose is used in biomedical and industrial applications, but the molecular mechanisms of synthesis are unclear. Unlike most bacteria, which make non-crystalline cellulose, Gluconacetobacter hansenii extrudes profuse amounts of crystalline cellulose. Its cellulose synthase (AcsA) exists as a complex with accessory protein AcsB, forming a 'terminal complex' (TC) that has...

this paper reviews the possible effects determined on polymeric food packaging films by the simultaneous application of pressure (p) and temperature (t) in high pressure pasteurization and sterilization treatments of packaged foodstuffs. both theoretical modeling and experimental issues are discussed. in fact reversible and irreversible effects that could occur in single film as well as in mult...
