The monomer 3-hexylthiophen-2,5-dicarboxaldehyde was synthetized from precursor 3-hexylthiophene by VilsmeierHaack reaction. Three p-type semiconductor polymers (PHT-P, PHT-B and PHT-H) were aldol condensation this with three different ketones (propanone, butanone hexanone). composites created adding PbS/ZnS nanoparticles to these polymers. Light absorption increased the red composites. Electri...

Arsole-containing conjugated polymers are a practically unexplored class of materials despite the high interest in their phosphole analogues. Herein we report the synthesis of the first dithieno[3,2-b;2',3'-d]arsole derivative, and demonstrate that it is stable to ambient oxidation in its +3 oxidation state. A soluble copolymer is obtained by a palladium-catalyzed Stille polymerization and demo...

We show that a relatively simple approach for controlling the colloidal synthesis of anisotropic cadmium selenide semiconductor nanorods can be extended to the size-controlled preparation of magnetic cobalt nanorods as well as spherically shaped nanocrystals. This approach helps define a minimum feature set needed to separately control the sizes and shapes of nanocrystals. The resulting cobalt ...

In this paper, a discrete event dynamic system (DEDS) approach is utilized to improve the reliability of a system from the faulttolerance viewpoint. We propose a systematic way to classify faults and failures quantitatively and to find tolerable fault event sequences embedded in DEDS’s. After this, the synthesis of a fault-tolerant supervisory control system is investigated. A case study of a p...

The synthesis and assembly of components are key steps in micro/nano device manufacturing. In this article, we report an optically controlled assembly method that can rapidly pattern micro/nano devices by directly assembling ions and nanomaterials without expensive physical masks and complex etching processes. Utilizing this controllable process, different types of device components (e.g., meta...
