摘要:
An enhanced optically sensitive medium is disclosed which uses an organic charge transfer complex as the switching material. The organic charge transfer complex includes at least one moiety in an oxidized state. An enhancement mechanism is taught which provides a secondary source of neutral molecules of said at least one constituent moiety in the neutral or altered oxidation state. For example, with CuTCNQ used as the switching material, the erasing characteristics can be improved by using a covering dispersion having a matrix polymer interspersed with neutral molecules of TCNQ.degree..

The invention is a method and device providing very high density information storage on an organometallic charge transfer data storage medium. The medium is switched from one state to another through the application of an electric field to the medium by the probe tip of a scanning tunneling microscope resulting in an observable change in the electron density of the surface of the medium. A STM tip is used to write, read and erase data via the organometallic charge transfer medium (e.g. TCNQ, or derivatives thereof).
摘要:
The charge transfer apparatus of the present invention comprises an optical storage medium of either a mixture of several charge transfer compounds of varying redox potential or a single amphoteric organic charge transfer compound capable of undergoing a multistage charge transfer reaction, and a source of optical energy, typically a laser. When the optical energy illuminates a spot on the optical storage medium, the spot switches to one of a plurality of optically detectable states.

A method and apparatus is described for neutralizing airborne pathogens in ventilated air, and in heating or air conditioning systems. The pathogen neutralization system is effective against a wide spectrum of pathogens, it incorporates commercially available components, and it can be readily integrated into commercial HVAC systems where it neutralizes airborne pathogens in large volumes of ventilated air in real time without any chemical reagents. Typically, the system has a flow-through reaction chamber that contains a UV light source that emits short intense flashes of broad-spectrum UV light, a source of water vapor or spray, and an ozone generator. The system generates highly reactive ozone intermediates by irradiating ozone gas with UV light in the presence of water droplets or water vapor. The pathogens that can be neutralized by this system include bacteria, viruses, spores, fungi and parasites.
摘要:
A multistate organic optical storage medium is disclosed, wherein an optical beam can switch any "data storage spot" on said optical storage medium into three or more memory states. The optical storage medium may consist of a mixture of bistate switching modules, or it may consist of large delocalized amphoteric molecules. The illuminated area of said optical storage medium will undergo an electrochemical topactic redox reaction which will cause certain moieties in the illuminated area to change oxidation state. By changing the intensity of the optical "write" beam the illuminated area can be switched to a plurality of specific states each state having a unique set of oxidation species. An optical/spectroscopic means is used to identify the presence of oxidation species and to "read" the data stored.
摘要:
A current-controlled, bistable threshold or memory switch comprises a polycrystalline metal-organic semiconductor sandwiched between netallic electrodes. Films of either copper or silver complexed with TNAP, DDQ, TCNE, TCNQ, derivative TCNQ molecules, or other such electron acceptors provide switching between high and low impedance states with combined delay and switching times on the order of 1 nanosecond. Switching behavior of a complex of the present invention is related to the reduction potential of the acceptor molecule.

The invention is a method and device providing very high density information storage on an organomellic DCNQI charge transfer data storage medium. The medium is switched from one state to another through the application of an electric field to the medium by the probe tip of a scanning tunneling microscope resulting in an observable change in the electron density of the surface of the medium.
摘要:
Vanadium dioxide thin films have been prepared from tetrravalent vanadium organic compounds via the sol gel process. The vanadium dioxide was deposited from an alcoholic solution. Films were annealed between 200.degree.-700.degree. C. under nitrogen to achieve complete dehydration and crystallization.
