Sociolgy theory states that though the mutal dependence condition equaly aplies to al social structures, the performance valuation of the resultant coperation varies acording to the goals of each structure. Howevr, the extant management acountig and control structures literature implicitly presues that utal dependence is relvant only to the organic ontrol structures context and not he mechanica...

Introduction: Since their formation, many meteorites have experienced significant degrees of alteration, by heat, impact, and fluid-mediated processes on their parent bodies [1]. Carbonaceous chondrites contain significant amounts of organic materials; a small proportion is present as volatile or soluble compounds, but the majority comprises insoluble, macromolecular material (IOM) [2]. Using t...

Although organic solar cells are a promising source of inexpensive photovoltaic (PV) power, their low efficiency must be improved. We address this problem in a radical departure from the conventional model of organic solar cells. Our architecture is based on photosynthesis that other example of organic solar cell technology, albeit optimized for two billion years. As in biology, we separate the...

The impact of the submolecular electron density on the X-ray diffraction profile of a layer-stacked thin film is studied experimentally and compared with numerical simulations based on the molecular structure and angular arrangement. Important structural information is contained in the X-ray diffraction profile of highly anisotropic molecular thin films, such as phthalocyanines. The results sho...

There is a growing interest in the development of organic nanomaterials for biomedical applications. An increasing number of studies focus on the uses of nanomaterials with organic structure for regeneration of bone, cartilage, skin or dental tissues. Solid evidence has been found for several advantages of using natural or synthetic organic nanostructures in a wide variety of dental fields, fro...

In the asymmetric unit of the title compound, C19H23NO2S·H2O, there are two independent organic mol-ecules and two water mol-ecules. Both organic mol-ecules exist as the zwitterionic form. The dihedral angles between the planes of the rings in the organic mol-ecules are 86.84 (10) and 88.77 (11)°. An intramolecular N-H⋯S hydrogen bond occurs. In the crystal, organic and water mol-ecules are lin...

The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications. Practical transistors require high mobility, large on/off ratio, low threshold voltage and high stability. Development of new organic semiconductors is key to achieving these parameters. Recently, organ...

The photoresponse of reversed bilayer organic photovoltaic device based on pentacene and C60 is examined, and the mechanism of photocurrent generation is shown to be different to that in conventional heterojunction devices, with free charge carriers generated at the electrode-organic interfaces rather than the organic heterojunction. This hypothesis is tested with silver nanoclusters incorporat...
