S. P. C. Alves, C. Santos, A. P. da Costa, M. Silva, C. Baleizão, J. P. S. Farinha, "Smart polymeric nanoparticles for boron scavenging"

 

SMART MATERIALS FOR BORON REMOVAL

Novel boron scavenging process. At room temperature the nanoparticles are expanded, promoting boron chelation to diol groups. At higher temperature the polymer shell collapses inducing nanoparticle flocculation. The nanoparticles can then be regenerated by pH treatment and reused.

The cover image is a reproduction of the painting "Lucifer Yellow" by Ana Tristany , of four polymer chains (blue) labeled with several LY fluorophores (yellow), each with a biotin at one chain-end (blue/black). The biotin groups are in the process of interacting with a streptavidine protein (red).

J.P.S. Farinha, J.M.G. Martinho, "Resonance Energy Transfer Between Dyes in Nanosized Domains at Polymer Interfaces".

Resonance energy transfer in nano-size domains at the interface between different polymers: The cover is a reproduction of the painting "Interfaces" (acrylic on canvas, 1.5 m x 1.5 m), a personal interpretation by artist Ana Tristany of nano-size domains located at the interface between different polymers (in black and grey), labeled with energy donor (red) and acceptor (green) dyes. The plot in white was pasted onto the image and represents the concentration profile of the dyes at the interfacial domain. The nanometer size dimensions of the domains match the typical lengthscale of FRET, allowing the determination of the size and distribution functions. The review paper Energy Transfer in Polymer Nanodomains, describe the tools necessary to extract information on the dyes distribution and the morphology of the interfacial domains
