Abstract:
A carbon nanotube film includes a plurality of carbon nanotubes. The plurality of carbon nanotubes is arranged approximately along a same first direction. The plurality of carbon nanotubes are joined end to end by van der Waals attractive force therebetween. The carbon nanotube film has a uniform width. The carbon nanotube film has substantially the same density of the carbon nanotubes along a second direction perpendicular to the first direction. The change in density across the width is within 10 percent. The present application also relates to a carbon nanotube film precursor and a method for making the carbon nanotube film.
Abstract:
The present disclosure provides a method for making a carbon nanotube wire structure. A plurality of carbon nanotube arrays is provided. One carbon nanotube film is formed by drawing a number of carbon nanotubes from each of the plurality of carbon nanotube arrays, whereby a plurality of carbon nanotube films is formed. The carbon nanotube films converge at one spot. The carbon nanotube wire structure is formed by treating the carbon nanotube films via at least one of a mechanical method and an organic solvent method.
Abstract:
Blockchains operate as decentralized, self-regulating systems that involve contributions from hundreds of thousands of participants who work on the verification and authentication of transactions occurring on the blockchain. The consensus mechanism within such a system provides the set of rules that determine the legitimacy of contributions made by the various participants of the blockchain. The consensus mechanism should not only be tolerant of faults but also have low latency in establishing consensus. Prior art solutions either could tolerate at most (n+1)/5 faults reaching consensus or execution of three or more communication steps to provide tolerance of arbitrary (Byzantine) faults or cannot guarantee strong safety property for an honest primary. To improve the speed of the consensus mechanism the inventors have established a BFT consensus protocol that operates with just two communication steps. The proposed protocol tolerates at most (n−1)/3 faults and provides strong safety guarantees for an honest primary.

A method for measuring intensity distribution of light includes a step of providing a carbon nanotube array located on a surface of a substrate. The carbon nanotube array has a top surface away from the substrate. The carbon nanotube array with the substrate is located in an inertia environment or a vacuum environment. A light source irradiates the top surface of the carbon nanotube array, to make the carbon nanotube array radiate a visible light. A reflector is provided, and the visible light is reflected by the reflector. An imaging element images the visible light reflected by the reflector, to obtain an intensity distribution of the light source.
