Abstract The diffusion kinetics of a molecular probe—rhodamine B—in ternary aqueous solutions containing poly(vinyl alcohol), glycerol, and surfactants was investigated using fluorescence correlation spectroscopy dynamic light scattering. We show that the characteristics rhodamine B in such complex systems is determined by synergistic effect crowding intermolecular interactions between chemical...
We describe a transparent and flexible field-effect transistor (FET) made from graphene and single-walled carbon nanotubes (SWNT) hybrid system. Graphene and vertically aligned SWNTs simultaneously grown by alcohol catalytic chemical vapor deposition (ACCVD) were employed as channel and source-drain electrode, respectively. Gate electrode was also made of SWNTs separated with a thin poly(vinyl ...
Mesoporous alumina and magnesia were prepared using various polymers, poly(ethylene glycol) (PEG), poly(vinyl alcohol) (PVA), poly(N-(2-hydroxypropyl) methacrylamide) (PHPMA), and poly(dimethylacrylamide) (PDMAAm), as porogenic structure matrices. Mesoporous alumina exhibits large Brunauer–Emmett–Teller (BET) surface areas up to 365 m2 g−1, while mesoporous magnesium oxide possesses BET surface...
