  • Publication number: 20230227790
    Abstract: Disclosed are methods of a method of making a nanostructure, comprising adding a component A (compA) protein to a solution comprising a component B (compB) protein under conditions that minimize shear stress, thereby forming a compA:compB complex. Further disclosed are methods of making a nanostructure, comprising (i) providing a first inlet fluid stream comprising a first protein and a second inlet fluid stream comprising a second protein, and (ii) contacting the first inlet fluid stream and the second inlet fluid stream to form an outlet stream, wherein mixing of the first protein and the second protein occurs in the outlet stream, thereby forming a protein complex comprises the first protein and the second protein. A microfluidic mixer may be used. The methods may further comprise purifying the compA:compB complex from excess compA, excess compB, and/or other impurities by filtering the solution with a 1,000 kDa membrane or an equivalent thereof.

  • Publication number: 20220088050
    Abstract: The present invention relates to a method of treating fatty liver disease in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a compound of Formula (I) 5?-N1N2N3N4N5N6-N7N8-dCm-dGc-N11N12N13N14N15N16-N17N18-3?.

  • Patent number: 9997564
    Abstract: Embodiments of the present disclosure generally relate to data storage systems, and more particularly, to a SHE-MRAM device. The SHE-MRAM device includes a memory cell array having a plurality of first leads, a plurality of second leads, and a plurality of memory cells disposed between the plurality of first leads and the plurality of second leads. The second leads are made of a material having large spin orbit interactions and high electrical resistivity. The SHE-MRAM device further includes a periphery circuitry having multiple pairs of transistors. The multiple pairs of transistors reduce the length a current has to flow through a second lead of the plurality of second leads. By limiting the distance a current can flow through the second lead, applying excessive voltage to the second lead is avoided.

  • Patent number: 9992726
    Abstract: A wireless communication system for use in a process environment uses mesh and possibly a combination of mesh and point-to-point communications to produce a wireless communication network that can be easily set up, configured, changed and monitored, thereby making a wireless communication network that is less expensive, and more robust and reliable. The wireless communication system allows virtual communication paths to be established and used within the process control system in a manner that is independent of the manner in which the wireless signals are sent between different wireless transmitting and receiving devices within the process plant. Still further, communication analysis tools are provided to enable a user or operator to view the operation of the wireless communication network to thereby analyze the ongoing operation of the wireless communications within the wireless communication network.

  • Patent number: 9927788
    Abstract: A process control system coordinates with an associated asset management system to implement a plant safety mechanism and, in particular, to prevent unintended changes to, or otherwise undesired operation of, one or more process control equipment resources in a process plant. A maintenance technician uses the asset management system to request access to one or more of the process control equipment resources. A process operator receives the request via the process control system and grants or denies the request. Process control equipment resources for which a process operator grants a request are inoperable, in part or in whole, by the process control system. Upon completion of the maintenance task, the maintenance technician requests to return control of the process control equipment resource to the process operator. The return is complete when the process operator acknowledges the return of the resource to the process control system.

  • Publication number: 20180069573
    Abstract: A device and method for incrementally updating the error detecting and correcting bits for an error corrected block of data in a cross point memory array is disclosed. When an error corrected block of data is modified, only the modified data bits and the incrementally updated error detecting and correcting bits are changed in the cross point memory device for improved performant and reduced impact to device endurance.

  • Patent number: 9812503
    Abstract: The present invention is a method of incorporating a non-volatile memory into a CMOS process that requires four or fewer masks and limited additional processing steps. The present invention is an epi-silicon or poly-silicon process sequence that is introduced into a standard CMOS process (i) after the MOS transistors' gate oxide is formed and the gate poly-silicon is deposited (thereby protecting the delicate surface areas of the MOS transistors) and (ii) before the salicided contacts to those MOS transistors are formed (thereby performing any newly introduced steps having an elevated temperature, such as any epi-silicon or poly-silicon deposition for the formation of diodes, prior to the formation of that salicide). A 4F.sup.2 memory array is achieved with a diode matrix wherein the diodes are formed in the vertical orientation.

  • Publication number: 20170271407
    Abstract: The present invention is a means and a method for manufacturing large three dimensional memory arrays. The present invention is a means and a method for addressing the WL and BL resistance by creating arrays having not only large plane conductors for each of the memory layers (WLs) but also for the opposite polarity common layer (BL). The present invention is also a means and a method to form via interconnections between the substrate logic and the respective layers of a multidimensional array. The present invention is also a way to operate an array in which the select device is unipolar but the array is above to be operated in a bipolar way. This facilitates a bipolar operation for memory cell technologies such as Resistive RAM (e.g., RRAM, ReRAM and Mem resistors).
