摘要:
A method of fabricating carbon nanotube arrays (CNTA) on an oxide catalyst layer is disclosed. In one embodiment, the oxide catalyst is a metal oxide. The metal oxide may be deposited on a substrate used as a support. The CNTA is grown on the oxide catalyst layer under conditions promoting CNT growth. CNT growth is dependent on temperature, concentration of oxidizing molecules and carbon availability. One embodiment of the method comprises depositing an oxide catalyst layer on the substrate, heating the catalyst layer at certain rates to the target temperatures, adding oxidation molecules for the pretreatment of the oxide catalyst layer, and growing the array on the substrate. The oxide catalyst layer may comprise a group VIII element.
摘要:
An electrical connector that comprises a connector body that has opposite first and second ends. The first end is configured to be coupled with a prepared end of a cable. A coupling member that has an interface end configured to interface with a mating connector and a free end opposite the interface end that is rotatable with respect to the connector body at the second end of the connector body. A resilient grounding member is disposed between an outer surface of the second end of the connector body and the free end of the coupling member. Each of the connector body, the coupling member, and the resilient grounding member is conductive thereby creating a grounding path between the connector body and the coupling member.
摘要:
A connector for terminating a coaxial cable that comprises a connector body that has a first end adapted to receive the coaxial cable and a second end adapted to couple with a mating connector. A locking sleeve that has an interface end is engageable with the first end of the connector body. The locking sleeve includes an outer engagement ring spaced from the interface end thereby defining an outer annular receiving area between the outer engagement ring and the interface end. The outer annular receiving area is configured to receive the first end of the connector body in an interference fit. The locking sleeve is axially moveable relative to the connector body between a holding position in which the locking sleeve is detachably coupled to the connector body and a locked position in which the locking sleeve is inseparably coupled to the connector body.
摘要:
The invention relates to methods for introducing target biopolymers (e.g., nucleic acid molecules, proteins, etc.) and other compounds (e.g., non-polymeric organic molecules, such as steroids) into cells (e.g., eukaryotic cells). The invention further relates to compositions comprising target biopolymers and other compounds. In certain aspects, the invention relates to the deposition of target biopolymer-containing mixtures onto surfaces optionally followed by contacting these target biopolymer-containing mixtures with cells (e.g., eukaryotic cells). Additionally, when the target biopolymers are nucleic acid molecules, expression of these nucleic acid molecules by cells which are contacted with the target biopolymers may be monitored or detected.

摘要:
A method of dispersing a metal or metal oxide within a CNT or CNT array, comprising exposing the CNT or CNT array to a solution containing a metal compound in a non-aqueous liquid; and removing the non-aqueous liquid from the CNT or CNT array. Nanoparticles were homogenously deposited within millimeter-long carbon nanotube array (CNTA). After modified with nanoparticles, CNTA changes from hydrophobic to hydrophilic. The hydrophilic composite electrodes present ideal capacitive behavior with high reversibility. The novel, nano-architectured composite demonstrates strong promise for high-performance thick and compact electrochemical supercapacitors.
