  • Publication number: 20220242976
    Abstract: Disclosed are support-activators and catalyst compositions comprising the support-activators for polymerizing olefins in which the support-activator includes clay heteroadduct, prepare from a colloidal phyllosilicate such as a colloidal smectite clay, which is chemically-modified with a heterocoagulation agent. By limiting the amount of heterocoagulation reagent relative to the colloidal smectite clay as described herein, the smectite heteroadduct support-activator is a porous and amorphous solid which can be readily isolated from the resulting slurry by a conventional filtration process, and which can activate metallocenes and related catalysts toward olefin polymerization. Related compositions and processes are disclosed.

  • Publication number: 20220244916
    Abstract: A compute-in-memory (CIM) device has a memory array with a plurality of memory cells arranged in rows and columns. The plurality of memory cells includes a first memory cell in a first row and a first column of the memory array and a second memory cell in the first row and a second column of the memory array. The first and second memory cells are configured to store respective first and second weight signals. An input driver provides a plurality of input signals. A first logic circuit is coupled to the first memory cell to provide a first output signal based on a first input signal from the input driver and the first weight signal. A second logic circuit is coupled to the second memory cell to provide a second output signal based on a second input signal from the input driver and the second weight signal.
