The study of drying and wetting cycles in soils is important due to their effects on plant nutrition and soil fertility as well as environmental issues. Therefore, a laboratory experiment was set up with a completely randomized design and factorial arrangement in three replications to identify the influence of wetting and drying cycles in combination with or without application of organic acids...

Introduction: Organization structure and manpower constitute two basiccomponents of anorganization and both are necessary for stablishing anorganization. The aim of this survey was to investigate the type of theorganization structure (mechanic and organic) from viewpoint of senior andjunior managers in Shiraz teaching hospitals and creativity in each of these two structures.Methods: In this cro...

Abstract Organic–metal and organic–organic interfaces play crucial roles in charge injection in, and transport through, organic thin film devices. Their electronic structure, chemical properties and electrical behaviour must be fully characterized and understood if engineering and control of organic devices are to reach the levels attained for inorganic semiconductor devices. Recent fundamental...

The historical background and recent progress in the development of organic electronics and photonic crystals, particularly tunable photonic crystals realized by combining photonic crystal structure with functional organic molecules, are discussed. The novel characteristics of organic electronic devices with mainly conducting polymers, which are related to the optical effects, and the tunable p...

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.

The electronic structure of an electron-acceptor molecule, tetracyanoethylene (TCNE), on graphene was investigated using the first-principles method based on density functional theory. It was theoretically demonstrated that a p-type graphene can be obtained via charge transfer between an organic molecule and graphene. Both the carrier concentration and band gap at the Dirac point can be control...

Blue top-emitting organic light-emitting devices (TOLEDs) with highly saturated color were developed by microcavity effect. The device structure studied was glass/reflective silver/indium-tin oxide (ITO)/organic electroluminescent stack/semi-transparent cathode (calcium/silver). By changing the thicknesses of ITO and organic layers in the microcavity structure device doped with p-bis(p-N, Ndi-p...

Inorganic-organic hybrid crystals containing α-octamolybdate (Mo8) or hexamolybdate (Mo6) were isolated by using hexadecyltrimethylammonium (C16) surfactant. The packing mode of the inorganic layers depended on a difference in the polyoxomolybdate molecular structure. The structure for both crystals consisted of alternate stacking of C16 organic bilayers and polyoxomolybdate inorganic layers wi...

A new class of organic-inorganic hybrid aerogels having small pores and narrow pore size distribution are synthesized from well-dispersed clay platelets in water as base catalyst. Clay-catalyzed organic gels have strong advantage in controlling nanopore structure as well as reducing drying shrinkage by reinforcing the organic network with inorganic platelets.
