Abstract: A device suitable for forming spherical particle clusters from fine powder is a device through which spherical particle clusters having a controlled particle size and a controlled hardness can be prepared from the fine powder by using a rolling granulation principle without adding any solution or solid binder. In particular, the device includes the following components: a) a preforming device for preforming particle clusters formed from fine powder, so that the particle clusters have a certain strength and shape while conveying the particle clusters to a next step at a certain speed; b) a spheroidizing device for further strengthening the particle clusters formed by a) the preforming device, so that the particle clusters have a higher sphericity and hardness; and c) a grading device for sieving the particle clusters spheroidized by b) the spheroidizing device to obtain particle clusters of different particle size ranges.

Abstract: Various methods of reshaping and recycling thermoset polymers and composites containing thermoset polymers are provided. The methods involve the bond exchange reaction of exchangeable covalent bonds in the polymer matrix with a suitable small molecule solvent in the presence of a catalyst.

Abstract: A system and method for securely sharing metadata among virtualized network functions (VNFs) disposed within a cluster of host computers includes a distributed forwarding and metadata sharing (DFMS) framework that forwards received data packets and provides remote direct memory access (RDMA) enabled sharing of secured metadata among the VNFs from more than one host computer in the cluster of host computers, and a DFMS controller that resides in the cluster of host computers as a VNF and registers VNFs in the cluster to at least one group of VNFs in the cluster and assigns access rights to the metadata of VNFs within respective groups of VNFs in the cluster. In operation, each registered VNF in a group in the cluster uses RDMA requests to access the metadata for other registered VNFs in the group in the cluster to which the each registered VNF in the group has access rights.
