The fast photopolymerization of different multifunctionalacrylates was analyzed by means of photorheology.The materials studied included a penta/hexaacrylatemonomer and two different acrylated hyperbranchedpolymers. The sensitivity of the commercial rheome ...
The objective of this study was to investigate the behavior of highly functional acrylates, during isothermal ultraviolet (UV) curing. The materials included a pentafunctional acrylate and two acrylated hyperbranched polymers, one with a stiff polyester co ...
Free radical polymerization is the most frequently used technique to produce synthetic polymers. They represent more than 25% of the total volume of materials made by the mankind. 3% thereof correspond to water soluble polymers with annual growth rates est ...
Carrier-mediated drug delivery has emerged as a powerful methodology for the treatment of various pathologies. The therapeutic index of traditional and novel drugs is enhanced via the increase of specificity due to targeting of drugs to a particular tissue ...
A precise data set describing the kinetics of the free radical copolymn. of acrylamide/acrylic acid (AM/AA) in the range of low total monomer concn. as a function of the pH, total monomer concn., initiator concn., and comonomer ratio is presented. Strong i ...
A new target in AIDS therapy development is HIV-1 integrase (IN). It was proven that HIV-1 IN required divalent metal cations to achieve phosphodiester bond cleavage of DNA. Accordingly, all newly investigated potent IN inhibitors contain chemical fragment ...
Three anthraquinone dyes with carboxylic acid as anchoring group are designed and synthesized as sensitizers for dye-sensitized solar cells (DSSCs). Preliminary photophys. and photoelectrochem. measurements show that these anthraquinone dyes have very low ...
A conceptually novel macrolactonization protocol has been developed. It is a domino process involving a sequence of: (1) protonation of 5-aminooxazole leading to the electrophilic iminium salt; (2) trapping of the iminium species by the neighboring C-termi ...
The dispersion of nanosized gamma aluminas with high specific surfaces areas (100 m2 /g) and primary particle sizes around 20 nm, using polyacrylic acid, has been investigated. The effect of pH and polymer concentration showed that the highest density gree ...
5-Pyrimidyllithium species are fairly stable when the metal is flanked by two electron-withdrawing substituents such as trifluoromethyl and chlorine or bromine. Thus, the corresponding 5-carboxylic acids are produced in high yields from 4,5-dibromo-6-(trif ...
