Sputtering-Based Metal Ion Sources and their Applications

Metal ion-dependent DNAzymes and their applications as biosensors.

Long considered to serve solely as the genetic information carrier, DNA has been shown in 1994 to be able to act as DNA catalysts capable of catalyzing a trans-esterification reaction similar to the action of ribozymes and protein enzymes. Although not yet found in nature, numerous DNAzymes have been isolated through in vitro selection for catalyzing many different types of reactions in the pre...

Noble Metal Nanoparticles Prepared by Metal Sputtering into Glycerol and their Grafting to Polymer Surface

This chapter summarizes the basic information about elementary characteristics and tech‐ nology of preparation of noble metal nanoparticles. The introduction gives some basic in‐ formation on the history of development in this area, especially in terms of dimensionality of metal nanostructures and their possible applications.The first subsec‐ tion is devoted to the preparation and characterizat...

Emissive Membrane Ion Thrusters and Their Applications

The mechanism of operation of a new thruster concept that utilizes solid-state ionic membranes to convert molecules into ions and transmit them to a surface from which they can be extracted into energetic beamlets thereby producing thrust is described. Results of recent experiments are used to estimate the performance of the thruster and the masses of various components required for it to perfo...

Novel Metal Nanomaterials and Their Catalytic Applications.

In the rapidly developing areas of nanotechnology, nano-scale materials as heterogeneous catalysts in the synthesis of organic molecules have gotten more and more attention. In this review, we will summarize the synthesis of several new types of noble metal nanostructures (FePt@Cu nanowires, Pt@Fe₂O₃ nanowires and bimetallic Pt@Ir nanocomplexes; Pt-Au heterostructures, Au-Pt bimetallic nanocomp...
