Acetylene Gas-Sensing Properties of Layer-by-Layer Self-Assembled Ag-Decorated Tin Dioxide/Graphene Nanocomposite Film

This paper demonstrates an acetylene gas sensor based on an Ag-decorated tin dioxide/reduced graphene oxide (Ag-SnO₂/rGO) nanocomposite film, prepared by layer-by-layer (LbL) self-assembly technology. The as-prepared Ag-SnO₂/rGO nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectrum. The acetylene...

Layer-by-Layer DNA film synthesis via branched hybridization

A new Layer-by-Layer (LbL) DNA film synthesis, where the driving force is the natural DNA hybridization, is presented in this work. The DNA films were synthesized via a branched mechanism and do not include any chemical binders between each layer as it is the case for film obtained by other synthesis paths. Kinetics of film formation were monitored by mass measurements with an electroacoustic n...

Buffer-Layer-Assisted Growth of Nanocrystals: Ag-Xe-Si(111)

Silver nanocrystals have been grown on Xe buffer layers at 50 K. These 3D nanocrystals are delivered to Si(111)-s7 3 7d surfaces when the Xe layer is desorbed, but the density observed on the surface depends strongly on the buffer layer thickness. This dependence reflects an unusual desorption-assisted coalescence process. The results suggest that buffer-layer-assisted growth can be used to pre...

Layer-by-Layer Epitaxial Growth of Defect-Engineered Strontium Cobaltites.

Control over structure and composition of (ABO3) perovskite oxides offers exciting opportunities since these materials possess unique, tunable properties. Perovskite oxides with cobalt B-site cations are particularly promising, as the range of the cation's stable oxidation states leads to many possible structural frameworks. Here, we report growth of strontium cobalt oxide thin films by molecul...
