چکیده
Nanoporous materials with 3-D interconnected channels and large surface areas have been known to be technologically useful for a wide spectrum of applications, particularly in the fields energy storage conversion, supported catalysis separation technology. For first time, we herein report upon an original approach elaborate nanoporous polymers, especially thermosets, bicontinuous morphology. The versatility this strategy stems from possibility using gold (np-Au) as template replicate any polymeric material. Depending on solubility behavior polymer, infiltration solution used step pore filling is different, i.e. preformed polystyrene (PS) or pure liquid dicyanate monomers followed by in-situ polymerization case thermosetting polycyanurate (PCN). After selective quantitative dissolution np-Au KI/I2 solution, resulting np-PS np-PCN, respectively, takes inverse morphology np-Au, evidenced SEM Fourier transform analysis. Both np-PCN frameworks present well-defined nanostructures homogeneous size distribution over entire volume processed samples. This new pathway very promising not only because its terms polymer diversity but also precisely tuning nanostructure polymers.

DNA-templated synthesis: more versatile than expected.
It has been known for almost twenty years that nucleic acids may promote chemical reactions. Catalytic nucleic acids can be found in nature or evolved through in vitro selection processes.[1] Structural and functional investigations suggest that catalytically active nucleic acids act in a similar manner to enzymes: they promote chemical reactions through the precise spatial alignment of the rea...

Gold nanoparticles were synthesized by chemical reduction of HAuCl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. Sonication time as the main affecting factor on the nanoparticle size was investigated. The characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...

متن کاملImprinted Polymers: Versatile New Tools in Synthesis
The use of molecularly imprinted polymers in synthetic organic chemistry is reviewed. These materials are prepared in the presence of a template for which they carry a functional and stereochemical “memory” and can be likened to artificial antibodies or enzymes. Their unique properties have been exploited by the use of imprinted polymers as stereoand regio-selective solid supports in condensati...
