The cellulose-based dispersant forms hydrogen bonds with one or more carbonyl-groups on the capacitive particles comprising carbon. The dispersion is combined with an electroactive material, an electrically conductive material, and a binder to form a slurry. The slurry is applied to a current collector and solidified to form the capacitor-assisted hybrid electrode having a composite hybrid active layer on the current collector. Capacitor-assisted hybrid electrodes formed from such methods are also provided.

  • Patent number: 11838806
    Abstract: Techniques for multiple call types for a call event are described and may be implemented via a wireless device to enable multiple connections for wireless calls. For instance, redundant connections for a call event of a wireless device are established via different call types and utilized to exchange call media of the call event. In at least some implementations, call media from the different call types is combined to provide a combined media stream for output as part of the call event. Thus, techniques for multiple call types for a call event are applicable to increase call quality in different scenarios and environments, such as in situations where a primary call connection experiences an anomaly condition that causes quality call degradation.

  • Patent number: 11833212
    Abstract: A linker peptide for constructing a fusion protein. The linker peptide comprises a flexible peptide and a rigid peptide. The flexible peptide consists of one or more flexible units. The rigid peptide consists of one or more rigid units. The flexible unit comprises two or more amino acid residues selected from Gly, Ser, Ala, and Thr. The rigid unit comprises a human chorionic gonadotropin ?-subunit carboxy-terminal peptide (CTP) bearing a plurality of glycosylation sites. The linker peptide can more effectively eliminate mutual steric hindrance of two fusion molecules, decreasing a reduction/loss of polymerization or activity resulting from improper folding of an active protein or a conformational change. On the other hand, the negatively charged, highly sialylated CTP can resist renal clearance, further prolonging a half-life of a fused molecule and enhancing bioavailability of a fused protein.
