The present invention relates to carbon based materials that are employed for hydrogen storage applications. The material may be described as the pyrolysis product of a molecular precursor such as a cyclic quinone compound. The pyrolysis product may then be combined with selected transition metal atoms which may be in nanoparticulate form, where the metals may be dispersed on the material surface. Such product may then provide for the reversible storage of hydrogen. The metallic nanoparticles may also be combined with a second metal as an alloy to further improve hydrogen storage performance.
摘要:
A magnetron sputter reactor for sputtering deposition materials such as tantalum, tantalum nitride and copper, for example, and its method of use, in which self-ionized plasma (SIP) sputtering and inductively coupled plasma (ICP) sputtering are promoted, either together or alternately, in the same or different chambers. Also, bottom coverage may be thinned or eliminated by ICP resputtering in one chamber and SIP in another. SIP is promoted by a small magnetron having poles of unequal magnetic strength and a high power applied to the target during sputtering. ICP is provided by one or more RF coils which inductively couple RF energy into a plasma. The combined SIP-ICP layers can act as a liner or barrier or seed or nucleation layer for hole. In addition, an RF coil may be sputtered to provide protective material during ICP resputtering. In another chamber an array of auxiliary magnets positioned along sidewalls of a magnetron sputter reactor on a side towards the wafer from the target. The magnetron preferably is a small, strong one having a stronger outer pole of a first magnetic polarity surrounding a weaker outer pole of a second magnetic polarity and rotates about the central axis of the chamber. The auxiliary magnets preferably have the first magnetic polarity to draw the unbalanced magnetic field component toward the wafer. The auxiliary magnets may be either permanent magnets or electromagnets.
摘要:
A method of using Raman imaging microscopy to evaluate drug actions in living cells is disclosed. Specifically the invention describes the methods of using Raman imaging microscopy to detect drug uptake, distribution, binding, and metabolism in a single cell, and to study drug pharmacokinetics at the cellular level. The method involves measuring the Raman image of both the drug and the cell. Control images and post-treatment images of the cell were studied. Ratio images were calculated and the requisite information was obtained from a study of the intensity of the bright areas in the ratio images.
摘要:
A transducer cell array for electrochemical and electromechanical spectroscopy testing. The array has rows and columns of electrolytic volume cell elements that are spatially uniform. A reference electrode is common to all volume elements. Each counter electrode is individually addressable. The total impedance response provides a spatial image of the surface being tested.
摘要:
A novel plastic composition and method for making the same comprising a host polymer having substantially uniformly distributed therethrough a non-miscible liquid crystal polymer and red amorphous phosphorus. The liquid crystal polymer is present in a concentration sufficient to encapsulate said red amorphous phosphorus such that a substantial portion of the red amorphous phosphorus does not contact the host polymer.
摘要:
A double density plug and socket electrical connector employing the same form factor as existing 50 pin subminiature "D" connectors. Adapted for use on printed circuit boards the connector can compatibly interconnect 50 pin or 100 pin electrical connectors. The double fifty plug-socket connector can carry a multiple byte wide SCSI bus.
摘要:
A water well and storage tank control system for use in isolated areas that utilizes a solar power source in conjunction with pneumatic pump apparatus for lifting well from a well bore hole for surface deposit in a storage tank. A solar power panel functions to continually charge into a storage battery which, in turn, is periodically applicable to energize a pump/compressor to generate air at increased pressure for conduction down the well bore. An airjet chamber immersed beneath the water level in the well bore receives input of the air at increased pressure and evacuates well water upward through a delivery pipe to a surface storage tank.
摘要:
Raman instrumentation for detecting for the presence of a molecular species in a including: a source of radiation for pumping the sample; apparatus for controlling the frequency and pulse width of radiation from the pumping source; a Raman spectrometer including a detector and means for collecting scattered photons from the sample; a radiation source for probing the sample; means for directing radiation from the probing source to the sample; and means to interface the spectrometer with the source of radiation for pumping. The radiation source for probing is, preferably, a monochromatic light source emitting radiation in at least one of the group including UV, visible, and near infrared radiation and, preferably, in the range of 220-1080 nm. The photons collected from the sample include elastically and inelastically scattered photons, and the spectrometer further including means for rejecting the elastically scattered photons. The pumping source is a microwave source.
