By combining supercritical drying technique with AAO template-assisted electrodeposition, noncollapsed, vertically aligned, and free-standing nanowire arrays on a conductive Au film have been fabricated. We also demonstrate that these free-standing nanowire arrays can be feasibly used for fabricating nanowire-based electrically driven devices.

Particles of fungicide encapsulated in lecithin and β-glucans were obtained in order to improve the action of the product against Botrytis cinerea. For this purpose, supercritical drying processes such as PGSS and SAS were performed and compared to conventional spray-drying. It was concluded that SAS is not a suitable process for these products. However, particles were well dried by any of the ...

Synthesized new Al and Zr-MOFs with bipyridine • links for isoreticluar metallation. Developed aziridation reactions to introduce • ethanediamine group (-NHCH2CH2NH2) on newly prepared MOFs with amino groups. Began metal-doping experiments for immobilization • of metal complexes. Environment of the metal coordination sites was • studied by the extended X-ray absorption fine structure spectrosco...

Abstract In this paper we present a comparison of aerogels which are dried under different conditions. Of those, most important the solvent, temperature, and pressure. Criteria rely mostly on results from analysis nitrogen adsorption experiments, as well transmission electron microscopy imaging. Platinum loaded indium oxide were picked model system for study they can be used highly effective he...

A number of polymers used in the production of carriers for drug delivery applications, possessing high surface area, appropriate surface chemistry and porosity, chemical stability and low cost have been investigated. One of these promising candidates are natural polysaccharides such as alginic acid sodium salt, guar gum, xanthan gum and chitosan due to their outstanding merits. They are simila...

One of the most important goals of tissue engineering is the design and the generation of a biocompatible porous 3-D structure, with high porosity, high interconnectivity and homogenous morphology. Nevertheless, the implantation of engineered biomaterials might cause local inflammation because of the host’s immune response. To overcome this limitation, in this study, 3-D polymeric composite sca...
