Abstract: A given policy file is obtained at a publishing node of a decentralized system of nodes, wherein the given policy file defines a policy that applies to at least a subset of nodes in the decentralized system of nodes. The given policy file is sent to a decentralized storage network for storage therein. Storage metadata is received from the decentralized storage network, wherein the storage metadata represents address information associated with storage of the given policy file in the decentralized storage network. The publishing node generates policy file retrieval metadata based on the storage metadata received from the decentralized storage system. The policy file retrieval metadata is sent to a blockchain network for storage therein. One or more querying nodes of the decentralized system of nodes access the blockchain network to obtain the policy file retrieval metadata in order to then retrieve the policy file from the decentralized storage network.

Abstract: A boron heterocyclic compound has a structure represented by Formula (I): in which L represents a single bond, a substituted or unsubstituted phenyl, a substituted or unsubstituted naphthyl, a substituted or unsubstituted anthryl, and D is mainly selected from carbazolyl and derivative groups thereof, acridinyl and derivative groups thereof, or diarylamino and derivative groups thereof. In the boron heterocyclic compound, an acceptor unit is bonded through a boron heterocyclic SP3 linking moiety, which shortens the conjugation length, increases the energy level, and also further improves the thermodynamic stability of the molecule. In addition, the short conjugate axis reduces intramolecular charge transfer and narrows luminescence spectrum to some extent. The compound can be used as a TADF material. Since the light-emitting layer of the light-emitting device does not contain noble metals, the cost thereof can be greatly reduced.

Abstract: The present invention provides a method for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol. The catalyst used in the method is prepared by supporting a noble metal and a promoter on an organic polymer supporter or an inorganic hybrid material supporter, wherein the supporter is functionalized by a nitrogen-containing ligand. When the catalyst is used in the hydrogenolysis of tetrahydrofurfuryl alcohol to prepare 1,5-pentanediol, a good reaction activity and a high selectivity can be achieved. The promoter and the nitrogen-containing ligand in the supporter are bound to the catalyst through coordination, thereby the loss of the promoter is significantly decreased, and the catalyst has a particularly high stability. The lifetime investigation of the catalyst, which has been reused many times or used continuously for a long term, suggests that the catalyst has no obvious change in performance, thus reducing the overall process production cost.

Abstract: The precision lapping and polishing device for external cylindrical surface of disk part and its taper error adjustment method. The device composes a circular baseplate, slant rails, baffles, pressure plates, copper blocks, a washer blanket; blanket plates, a set of bead shafting, a friction driving wheel, a DC motor, a mobile power supply, a LED lamp and a cover body. By adopting the working principle that the generatrix rotates around the fixed axis to form the cylindrical surface, the ultra-precision machining of the cylindrical surface of disk part is realized. The radial-continuous-automatic-micro feeding of the disk part is realized by thinning the thickness of the circular baseplate which is internally tangent to the generatrix of the circular baseplate during the process of lapping and polishing. The device has the advantages of operating simply, adjusting conveniently, low cost and is of important value for popularization and application.
