Micellles of poly(cyclohexyl metharylate)-block-poly(2-vinylpyridine) (PCMA-b-P2VP) block copolymer in methanol were used as nanoreactors to fabricate FeCl3 nanoparticles. Then the FeCl3-loaded micelles solution was used as an ink to print films with polydimethylsiloxane (PDMS) stamps, different morphologies of the FeCl3-loaded micellar films were left onto silicon substrates after printed. After...
In this work, we report on the use of an AFM - Atomic Force Microscope for positioning of 50 nm-diameter, gold nanoparticles protected by an octanethiol monolayer into a gap between two nanoelectrodes realized by AFM lithography. Nanoparticles depositions were performed by using the spin casting technique, in order to obtain isolated nanoparticles, uniformly dispersed on the sample. Then, the manipulation...
This paper summarizes a Ag carboxylate ink technology for patterning circuits on heat-sensitive substrates. Low temperature processes for making circuits is becoming one of the key issues for printed electronics primarily because of the potentials of heat-sensitive substrates such as PET films and papers. The authors have developed ??-ketocarboxylate Ag inks that can be cured around 100??C. The electrical...
Highly oriented polytetrafluoroethylene (HOPTFE) was prepared by friction-transfer method on glass substrates under uniform deposition conditions. The distribution of finely divided HOPTFE macromolecular ridges was investigated by atomic force microscopy, pointing out that HOPTFE molecular films may induce topographically directed self-assembly processes. Furthermore, on the basis of their surface...
We present a new class of plasmonic substrates where silver nanoparticles are impregnated into a polycarbonate host. The substrates are shown to be exceptional candidates for SERS and metal enhanced fluorescence applications.
Zinc oxide (ZnO) nanoparticles is an attractive candidate and gain attention for their novel properties and promising applications such as optoelectronic devices by virtue of their high surface to volume ratio and molecular absorption and desorption characteristics. Ultraviolet light emmiters, gas sensor (particularly for hydrogen) etc. are some of the potential applications of this wide direct band...
