摘要： In some embodiments, the present disclosure pertains to methods of producing a graphene hybrid material by exposing a graphene precursor material to a laser source to form a laser-induced graphene, where the laser-induced graphene is derived from the graphene precursor material. The methods of the present disclosure also include a step of associating a pseudocapacitive material (e.g., a conducting polymer or a metal oxide) with the laser-induced graphene to form the graphene hybrid material. The formed graphene hybrid material can become embedded with or separated from the graphene precursor material. The graphene hybrid materials can also be utilized as components of an electronic device, such as electrodes in a microsupercapacitor. Additional embodiments of the present disclosure pertain to the aforementioned graphene hybrid materials and electronic devices.

摘要： The present invention provides methods of forming graphene films on various non-catalyst surfaces by applying a carbon source and a catalyst to the surface and initiating graphene film formation. In some embodiments, graphene film formation may be initiated by induction heating. In some embodiments, the carbon source is applied to the non-catalyst surface before the catalyst is applied to the surface. In other embodiments, the catalyst is applied to the non-catalyst surface before the carbon source is applied to the surface. In further embodiments, the catalyst and the carbon source are applied to the non-catalyst surface at the same time. Further embodiments of the present invention may also include a step of separating the catalyst from the formed graphene film, such as by acid etching.

摘要： The present invention discloses a digital signature scheme based on braid group conjugacy problem and a verifying method thereof, wherein the signatory S selects three braids xεLBm(l), x′εBn(l), aεBn(l), and considers braid pair (x′,x) as a public key of S, braid a as a private key of S; Signatory S uses hash function h for a message M needing signature to get y=h(M)εBn(l); generating a braid bεRBn−1−m(l) randomly, then signing the message M with the own private key a and the braid b generated randomly to obtain Sign(M)=a−1byb−1a; a signature verifying party V obtains the public key of S, calculating the message M by employing a system parameter hash function h, obtaining the y=h(M); judging whether sign(M) and y are conjugate or not, if not, sign(M) is an illegal signature, the verification fails; if yes, sign(M) is a legal signature of message M; the present invention avoids the problem of k-CSP in SCSS signature scheme of prior art, and improves the security of signature algorithm and reduces the number of braids involved and the number for conjugacy decision without reducing security, thereby improving the operation efficiency of signature.
