Abstract: A method for the fractionation of reclaimed polymer in at least one solvent in a process for purifying reclaimed polymers plastic recycling to increase their use in secondary applications. The reclaimed polymer is dissolved in a solvent within a reactor vessel having a stack of perforated discs which are oscillated. The linear motion of the stack speeds up dissolution time to minutes rather than hours and the required polymer to solvent ratio can be increased to 0.3 to 10% wt addition. Temperature and time effects are used to fractionate polymers of differing molecular weights to provide purified and graded plastics for secondary use at a commercially viable scale.

Abstract: Methods, systems, and devices for access heatmap implementations at a host device are described. A host device may leverage access operation monitoring that is performed at a memory device, including various examples of signaling and management of monitoring configurations. For example, a memory device may maintain a storage location for tracking access operation occurrence, for which access operations of a given address may be mapped to multiple fields, and for which each field may be associated with access operations of a respective subset of the addresses. In some examples, such registers may be configured or accessed based on indications (e.g., commands, requests) from a host device, which may support dynamic access operation monitoring that is responsive to various operating conditions. In some examples, the host device may perform evaluations based on such minimum values associated with respective addresses to determine a distribution of data across various portions of memory.

Abstract: Methods, systems, and devices for access heatmap generation at a memory device are described. In some examples, a memory device may maintain a register for tracking access operation occurrence, for which access operations of an address of the memory device may be mapped to multiple fields of the register. In some cases, in response to a first access operation performed on a first address of the memory device, the memory device may increment a first field and a second field of the register and, in response to a second access operation performed on a second address of the memory device, the memory device may increment the first field and a third field of the register. In some examples, the memory device may maintain a second register having a set of fields that each indicate a respective address for which an access occurrence satisfies a threshold.
