    Single-Pot Fabrication of Cellulose-Reinforced Solid Polymer Lithium-Ion Conductors

    Flexible power sources are essential to enable the autonomous operation of portable electronic systems. Conventional liquid electrolytes are not desirable for flexible batteries because of safety concerns surrounding the use of flammable organic solvents. A polymer electrolyte presents a promising alternative due to its higher mechanical integrity and lower risk of leaking solvent. Though they have such advantages, these electrolytes have lower ionic conductivity compared to conventional liquid electrolytes and are typically prepared using multistep process sequences. Here, we demonstrate a “single-pot” synthetic approach that affords a flexible, free-standing solid polymer electrolyte comprising cellulose-based nanocrystals and a cross-linked interpenetrating polymer network. Polyethylene oxide (PEO) is blended with poly­(ethylene glycol) dimethacrylate (PEGDMA), cellulose nanocrystals, and a lithium salt to afford the cross-linked polymer electrolyte upon UV irradiation. The cross-linked PEGDMA matrix provides good mechanical properties, while PEO is known for excellent electrochemical stability and its ability to solubilize lithium salts. The nontoxic cellulose additive also contributes to good mechanical properties and serves as a reinforcing filler. Soft and flexible polymer electrolytes were prepared with this approach. When the cellulose nanocrystal content reached 10 wt % relative to the PEO fraction, ionic conductivity was retained at 20 °C compared to the PEO control. The results provide a path toward sustainable, polymer electrolytes with performance metrics suitable for applications having a lower energy demand

    Effects of the anti-CTLA-4 immune checkpoint inhibitor antibody ipilimumab against MC1 PDXs implanted in hNSG mice. Once tumors reached ~ 150 mm3, animals were treated weekly with 10 mg/kg intravenous injections for up to 3 weeks; tumor volumes were evaluated twice weekly. The values represent the mean ± SEM (n = 8). (PPTX 50 kb

    a Evaluation of the percentages of human CD45+ TILs present in MC1 PDX tumors engrafted in hNSG mice and collected from animals treated with either vehicle control or anti-PD-1 antibody. The values represent the mean ± SEM (n = 8). b Schematic representation of the method used to determine the cytotoxic activity of TILs by measuring the levels of the lactate dehydrogenase (LDH), a stable cytosolic enzyme that is released upon TIL-induced tumor cell lysis. TILs were isolated from MC1 PDX tumors engrafted in hNSG mice and treated with either vehicle or anti-PD1 antibody that were cocultured with disaggregated MC1 tumor cells obtained from the corresponding PDX grown in nonhumanized NSG mice.
