Carbon nanotube particulates, compositions and use thereof
InactiveUS20050002851A1Suitable for useMaterial nanotechnologyNanoinformaticsParticulatesContact time
A method for making carbon nanotube particulates involves providing a catalyst comprising catalytic metals, such as iron and molybdenum or metals from Group VIB or Group VIIIB elements, on a support material, such as magnesia, and contacting the catalyst with a gaseous carbon-containing feedstock, such as methane, at a sufficient temperature and for a sufficient contact time to make small-diameter carbon nanotubes having one or more walls and outer wall diameters of less than about 3 nm. Removal of the support material from the carbon nanotubes yields particulates of enmeshed carbon nanotubes that retain an approximate three-dimensional shape and size of the particulate support that was removed. The carbon nanotube particulates can comprise ropes of carbon nanotubes. The carbon nanotube particulates disperse well in polymers and show high conductivity in polymers at low loadings. As electrical emitters, the carbon nanotube particulates exhibit very low “turn on” emission field.

Forming nanoscale patterned thin film metal layers
The specification describes a contact printing technique for forming patterns of thin films with nanometer resolution over large areas. The procedure, termed here “nanotransfer printing (nTP)”, relies on tailored surface chemistries for transferring thin films, typically metal films, from the raised regions of a stamp to a substrate when these two elements are brought into intimate physical contact. This technique is purely additive, it is fast (<15 s contact times), and the printing occurs in a single processing step at room temperature in open air. nTP is capable of producing patterns with a wide range of features with sizes down to ˜100 nm, and edge resolution better than 25 nm. Electrical contacts and interconnects have been fabricated for high performance organic thin film transistors (TFTs) and complementary inverter circuits, to demonstrate one of the many potential applications for nTP.

InactiveUS20090269287A1Prevent significant water lossGood dispersionCosmetic preparationsToilet preparationsCarrageenanRelative humidity
Disclosed are oral care compositions, particularly thickened dentifrices in liquid, paste or gel form comprising a binding / thickening system that also function effectively as humectant agent thereby replacing a significant portion or all of traditional humectant components such as glycerin, sorbitol and other polyols. The binding / thickening system comprise select carrageenans that provide a water viscosity of at least about 20 mPa·s in a 1.5% solution at 25° C. and effective water-binding capacity to prevent significant water loss from the composition when exposed to air to cause unacceptable drying out. For example, the water-binding capacity of the carrageenan must be effective such that there is no more than about 0.75% water loss from a dentifrice composition when exposed to air for 30 minutes at room temperature conditions and 50% relative humidity. The present dentifrice compositions exhibit increased dispersibility in saliva during use, which provides for increased contact time of the composition with the user's teeth and oral cavity tissues such that the active dental agents contained therein are more rapidly available to effect their beneficial activity.

Fuel reformer for mounting on a vehicle
InactiveUS6390030B1Keep for a long timeImprove fuel performanceHydrogen separation using solid contactChemical industryContact timeVaporization
A fuel reformer suited for mounting on a vehicle is provided. A raw material gas containing methanol and water is vaporized at a vaporization section 30. The vaporized gas flows horizontally to a reforming section 60 with monolithic catalyst 70. The reforming section is divided into two sides, a front side 62 and a rear side 64, with an interconnecting pipe 66 bent at 180 degrees, for connecting the front and rear sides. By making the material gas flow horizontally, even when the reformer is mounted to a vehicle which has a larger space in its horizontal direction than in its vertical direction, especially a small passenger car, the contact time period between gas and catalyst can be extended. By bending the reforming section by 180 degrees, the size of the reformer can be reduced so that the reformer is suited for mounting on a vehicle having limited space. Because the vaporization section 30 and the CO reducing section 80 can be placed adjacent to each other, by using heat generated at the CO reducing section, the heat loss during pre-heating of the methanol and water can be reduced.

Methane is used as the selective dehydrating agent for the production of 2,3,3,3-tetrafluoro-1-propene (R1234yf) from 2,2,3,3,3-pentafluoro-1-propanol. Supported transition metal catalysts are prepared and used for this reaction with high activity. Almost 58% selectivity to R1234yf is obtained at an alcohol conversion level of 60% using unsupported Ni-mesh as the catalyst. Pd and Pt show almost similar level of conversion; however, the selectivity to the desired product is low. The activity of the metal catalyst was found to be a function of the type of support material, activated carbon showing better activity than alumina. Different important process parameters such as temperature, pressure, and contact time are studied to optimize the process. High pressure and temperature are deleterious to the rate of 1234yf formation; yet, the highest yield to 1234yf is obtained while performing a reaction at 494° C. with a contact time of 23 sec.
