Interest in the properties of thin-film organic materials, especially regard ing organized monoand multilayer assemblies, has grown enormously recent years. The impetus for this renaissance-the relevance such structures and materials to biological interfaces membranes, corrosion protection, electrochemistry, wetting, adhesion, microelectronic cir cuit fabrication, example-has been discussed extensively (1,2). Such are clearly contributing significantly our more general under standing...

Flexible, stretchable, and spanning microelectrodes that carry signals from one circuit element to another are needed for many emerging forms of electronic optoelectronic devices. We have patterned silver by omnidirectional printing concentrated nanoparticle inks in both uniform high-aspect ratio motifs with minimum widths approximately 2 micrometers onto semiconductor, plastic, glass substrates. The can withstand repeated bending stretching large levels strain minimal degradation their...

Popping materials and devices from 2D into 3D Curved, thin, flexible complex three-dimensional (3D) structures can be very hard to manufacture at small length scales. Xu et al. develop an ingenious design strategy for the microfabrication of geometric mesostructures that derive out-of-plane buckling originally planar structural layout (see Perspective by Ye Tsukruk). Finite element analysis mechanics makes it possible two patterns, which is then attached a previously strained substrate...

We developed a simple approach to combine broad classes of dissimilar materials into heterogeneously integrated electronic systems with two- or three-dimensional layouts. The process begins the synthesis different semiconductor nanomaterials, such as single-walled carbon nanotubes and single-crystal micro- nanoscale wires ribbons gallium nitride, silicon, arsenide on separate substrates.

In this report, we describe the use of several analytical techniques, including X-ray absorption spectroscopy (XAS), electron microscopy, and diffraction, as tools for characterizing structural dynamics supported Pt nanoscale particles. We examined carbon-supported samples. Electron microscopy shows that particles in these samples (S1−S3) have average particle diameters roughly 20, 40, 60 Å respectively, while microdiffraction data provided evidence long-ranged ordering form face centered...

The future of nanoscience and nanotechnology depends critically on techniques for micro- nanofabrication. An emerging set methods, known collectively as soft lithography, uses elastomeric stamps, molds, conformable photomasks patterning two- three-dimensional structures with minimum feature sizes deep into the nanometer regime. powerful capabilities these together their experimental simplicity make them useful a wide range applications.

Low-energy electron diffraction and reflection-absorption infrared spectroscopy were used to study the monolayers formed by adsorption of n-alkane thiols [HS(CH2)mCH3] on both (111) (100) single-crystal gold substrates. Samples prepared dosing either from solution (m=15, 17, 18, 21) or in ultrahigh vacuum (m=0–9). On Au(111), ordered surface structures are obtained which can be indexed as (n√3×√3)R30°, where n varies 1 6. Au(100), short chain leads formation a c(2×2) overlayer while longer...
