in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
We investigate using Monte Carlo simulations in the NPT ensemble the self-assembly of disk-coil macromolecules with stacking interactions. The disk-coil molecules are composed of a planar disk that is covalently bonded to a single coil. In addition to commonly used amphiphilic interactions between the disk and coil portion of the molecules, we employ an attractive interaction between central mo...
Geholaspis (Geholaspis) pennulatus sp. nov. is described from females and males collected from forest leaf litter in Northern Iran. The new species can be easily recognised by its barbed setae j2 and z1, dorsal shield seta j5 located posterior to j6 and z6, a very wide ventri-anal shield, and the shape of the epistome. Geholaspis (G.) comelicensis Lombardini, 1962 is considered as a junior syno...
Brasilycus peruanus sp. nov. is proposed as new to science. Photographs of the habitus, antenna, pronotum, and aedeagus of the single specimen are presented. This new species represents the first record of the genus Brasilycus from Peru and is the fourth species in the genus recorded from South America.
The insect growth regulator methoprene can be mixed into the matrix used to comprise bags and other packaging materials. Different methodologies were utilized to evaluate the efficacy of different types of methoprene-treated packaging towards Tribolium castaneum (Herbst), the red flour beetle, and T. confusum Jacquelin duVal, the confused flour beetle, two common insect species that infest stor...
Highly ordered periodic mesoporous organosilica synthesized from a newly designed 9(10H)-acridone bridged organosilane precursor exhibited efficient light-harvesting antenna properties for visible light, at wavelengths up to 450 nm.
