Graphene oxide (GO) sheets were transferred by Langmuir-Blodgett technique on Si and SiO2/Si substrates. The surface pressure - area isotherms of 'amphiphilic' GO sheets at the air-water interface are found to be highly sensitive to subphase pH, whic

We have synthesized, characterized and studied the third-order nonlinear optical properties of two different nanostructures of polydiacetylene (PDA), PDA nanocrystals and PDA nanovesicles, along with silver nanoparticles-decorated PDA nanovesicles. T

A 'modified' Langmuir-Blodgett (MLB) technique has been developed as a simple, low cost, energy efficient and scalable alternative to conventional Langmuir-Blodgett (LB) technique for the transfer of graphene oxide (GO) monolayer sheets from air-wate

ZnO nanocrystallites were prepared by the oxidation of Zinc Arachidate-Arachidic Acid (ZnA-AA) composite multilayers grown on quartz and freshly cleaved mica substrates. Control of zinc content in the multilayers was achieved by the manipulation of t

Large area graphene oxide (GO) monolayer sheets were transferred on Si and SiO2/Si substrates by LangmuireBlodgett technique and reduced by heat treatment in the presence of graphite powder, inside an evacuated and sealed enclosure. Reduction at 1000

Graphene oxide (GO) monolayer sheets were transferred on to sputtered ZnO films and chemically grown ZnO nanorods by Langmuir-Blodgett technique. SEM images show that the GO sheets are well defined and uniformly distributed over both surfaces, namely

Nanocrystalline, zinc oxide films have been formed by the pyrolysis of zinc arachidate LB multilayers in oxygen ambient. FT-IR and UV–vis spectroscopy showed that on heat treatment, the pyrolysis began at ~200 °C and was complete at ~350 °C. TEM
