Graphene oxide (GO) sheet is used as a novel substrate for dip-pen nanolithography (DPN). After GO is transferred onto SiO(2) using the Langmuir-Blodgett technique, CoCl(2) is patterned on both GO and exposed SiO(2) substrates simultaneously by DPN, which is used for growth of different structured carbon nanotubes.
Single Langmuir-Blodgett (LB) bilayers derived from calix[n]arene-based surfactants (n = 4, 5 and 6) and poly(acrylic acid) (PAA) exhibit exceptional H(2)/CO(2) permeation selectivities. Evidence for the importance of ionic crosslinking and self-healing processes is presented.
Optical second harmonic generation (SHG) is used as a noninvasive probe of two-dimensional (2D) ferroelectricity in Langmuir-Blodgett (LB) films of copolymer vinylidene fluoride with trifluorethylene. The surface 2D ferroelectric-paraelectric phase transition in the topmost layer of LB films and a thickness independent (almost 2D) transition in the bulk of these films are observed in temperatur...
Stable, reversible conductance transitions and memory effects were observed in solid-state rotaxane-based Langmuir-Blodgett (LB) thin films. Taking advantage of the switching property, we have achieved reproducible nanometer-scale recording dots on rotaxane LB films via voltage application using a scanning tunneling microscope probe. The stable and easily controlled conductance switching makes ...
Multi-emissive compounds have attracted significant attention from the research community owing to wide array of potential application areas. However, move towards application, such systems should be readily immobilized by solution-based methods form soft materials as gels and films. Herein we report use Langmuir–Blodgett (LB) deposition easily immobilize luminescent lanthanide-based amphiphili...
