Switching element

RCT are designed to successfully solve a whole number of tasks in nuclear power when testing fuel elements, in aviation and space industry when testing construction materials, nozzles and engine units, turbine blades and parts, in electromechanical industry-cables switching elements, electric motors in defense sphere- charges, equipment in prospecting for research of rock distribution and detection of precious stones in samples. 

Metal-free, chloroaluminum phthalocyanine [14154-42-8] vanadyl phthalocyanine [13930-88-6], or magnesium phthalocyanines are sufficiently soluble in organic solvents and show enough bleachable absorption at 694.3 nm to serve as repeated Q-switching elements for mby lasers (qv) (180). Phthalocyanines have been used in other lasers as weU (181).

In principle any molecule able to exist in two reversible, switchable states can represents a molecular switch (bistable device) with potential to form part of molecular circuitry or act as molecular memory. An excellent component for switchable molecular devices is the 1,2-dithienylethene system, which has been exploited ingeniously by Lehn in a number of bistable systems.54 The core switching element is the transformation of the dithienylethene unit between two stable states as a function of the wavelength of incident radiation (Scheme 11.8). 

A substrate 10 of silicon comprising an array of switching elements is prepared. Contact pads such as 16 and 18 are connected to inputs of the switching elements. A protective nitride layer 20 is formed, with openings for the contact pads, on top of the substrate. A layer of photoresist 25 is patterned on top of the nitride layer. A layer of indium alloy 26, fabricated from a combination of indium, bismuth, lead, cadmium and tin, is deposited on the substate so as to contact the contact pads. This layer is built up such that its upper surface is higher than the structures that constitute the topography of the substrate. Portions of the conductive layer overlying the photo-resist are removed by a lift off process...

The results of our calculations are in a reasonable accordance with the data of recently papers [3-5] devoted to research of the same problems. It s clear that nanotubes of variable diameter of such kind must possess anisotropic conductivity and therefore can be used as switching elements in future nanodevices [6-7]. 

The Y-junctions of the various types are ones of the most interesting and perspective objects of modem experimental and theoretical researches because they can be used as switching elements in the future nanodevices. The paper is devoted to the theoretical studying only one of the simplest kind of Y-junctions. 

After the series of publications with the results of Papadopoulos group and other authors researches [3-7] the possibility of working out the technology of synthesis of Y-junctions of the turnpike type became obviously though in the near future. Measurements performed in [3-7] show clearly the perceptivities of using them as switching elements of future nanodevices. 

Different values for the minimum ignition energy are obtained in low voltage circuits with an ohmic (R) and inductive (L) load. As a switching element, a spark test apparatus with counter-rotating tungsten wires and a cadmium...

Niziol et al. review the linear and NLO properties of some catenanes and rotaxanes studied in solutions or tliln films. Techniques like UV-Vis spectrometry, second and tlilrd harmonic generation in thin films and electro-optic Kerr effects in solution have been employed. They review the synthesis and material processing of tlrese derivatives. Niziol et al. describe how the rotation rate of the macrocycle in catenane solutions is more than an order of magnitude larger than in rotaxanes. They comment on the factors on which the rate of rotation depends. This new class of molecules, with mobile subparts, is very likely to have useful applications including tire construction of synthetic molecular machines and all-optical switching elements. 

When conferred with a hydrophilic head (in this case a substituted trityl unit), and a hydrophobic (benzylic alcohol) tail, rotaxanes - branched [55] or otherwise - can be formed into Langmuir films in a manner similar to catenanes. Rotaxane 224+ - synthesized from its corresponding thread via the slipping approach - when incorporated into a device in a manner similar to the catenane 214+ also exhibited interesting electron-transport properties [56], Unlike the catenane-based device, there is no switching element built into the molecule. However, like the switchable catenane, the rotaxane 224+ has electroactive bipyridinium sites, whose presence can mediate the tunneling of...
