In this paper, we report direct patterning of metal nanostructures using an embossed solid electrochemical stamp. Microforming of solid superionic stamps using Si templates-analogous to polymer patterning in nano-imprint lithography-is explored. Silver sulfide (Ag(2)S)-a superionic conductor with excellent microforming properties-is investigated as a candidate material. Important parameters of the superionic stamp, including mechanical behavior, material flow during forming and feature recovery after embossing, are studied. Excellent feature transferability during embossing as well as etching is observed. To illustrate the capability of this approach silver nano-antennas with gaps < 10 nm were successfully fabricated. The possibility for large area patterning with stamp diameters > 6 mm is also demonstrated. Embossing-based metal patterning allows fabrication beyond two-dimensional nanofabrication and several patterning schemes are reported.

A particular kind of learning characterized by occurrence in very early life, rapidity of acquisition, and relative insusceptibility to forgetting or extinction. Imprinted behavior includes most (or all) behavior commonly called instinctive, but imprinting is used purely descriptively.
A nonlinear electrophoretic technique used to separate a variety of ionic compounds, ranging from small metal ions to large molecules like proteins. Unlike "linear" zone electrophoresis in which separating solute bands continually spread by diffusion or dispersion, isotachophoresis forms self-sharpening, adjacent zones of substantially pure solute whose concentrations often exceed several mgs/ml. In isotachophoresis a multianalyte sample is introduced between the leading electrolyte and the terminating electrolyte where the sample ions have lower electrophoretic mobilities than the leading ion but larger than the terminating ion.

A small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions.

Genetically and clinically heterogeneous disorder characterized by low birth weight, postnatal growth retardation, facial dysmorphism, bilateral body asymmetry, and clinodactyly of the fifth fingers. Alterations in GENETIC IMPRINTING are involved. Hypomethylation of IGF2/H19 locus near an imprinting center region of chromosome 11p15 plays a role in a subset of Silver-Russell syndrome. Hypermethylation of the same chromosomal region, on the other hand, can cause BECKWITH-WIEDEMANN SYNDROME. Maternal UNIPARENTAL DISOMY for chromosome 7 is known to play a role in its etiology.
