A New Low-Rate Stable Hydrogel Cathode For Aqueous Zn-Ion Batteries, Roya Rajabi, Shichen Sun, Jamil A. Khan, Morgan Stefik, Kevin Huang

Faculty Publications

Aqueous Zn-ion batteries (ZIBs) are attractive candidates for large-scale energy storage owing to the abundance, low cost, and intrinsic safety of Zn metal. However, their practical application is hindered by poor cycle stability, especially at low current densities, due to cathode dissolution and limited electrochemically active sites (EAS). Herein, a hydrogel-based cathode comprising ammonium vanadate, carbon black, and a Zn-ion-conducting carboxymethyl chitosan–acrylamide hydrogel matrix doped with Zn(ClO4)2 is reported. This design establishes a continuous Zn-ion-conducting network, thereby maximizing EAS density throughout the electrode volume. The ZIB with the hydrogel cathode exhibits outstanding cycling stability, with 77% capacity retention after 2000 …

Subjective Excessive Daytime Sleepiness And Frailty Progression In Veterans Over 50 With Insomnia, Mona Amirmazaheri

Walden Dissertations and Doctoral Studies

Frailty is common in aging veterans and linked to adverse outcomes. This retrospective cohort study of 6,824 veterans with insomnia examined whether excessive daytime sleepiness, sleep treatments, and PTSD affected frailty progression over four years. Frailty was measured using a validated index, with models adjusted for demographics and comorbidities, including chronic coronary insufficiency. Manuscript 1 showed that a higher Epworth Sleepiness Scale (ESS) score (range 0-24) was independently associated with a higher frailty index (FI) (p < .001). A clinical threshold of ≥11 indicated EDS and greater odds of frailty worsening compared to scores <11 (adjusted odds ratio (aOR) = 1.16, 95% CI [1.02, 1.32], p = .021). There was no significant interaction between ESS and time, suggesting that sEDS reflects persistently elevated frailty levels rather than accelerated decline. Manuscript 2 showed that nonpharmacologic sleep interventions were protective, while pharmacotherapy was associated with increased frailty risk. Cognitive behavioral therapy for insomnia was associated with lower odds of frailty worsening (aOR = 0.31, 95% CI [0.19, 0.53], p < .001), and continuous positive airway pressure therapy also reduced risk (aOR = 0.55, 95% CI [0.39, 0.76], p < .001). In contrast, sleep medications were associated with increased odds of frailty progression (aOR = 1.16, 95% CI [1.02, 1.32], p = .021). Manuscript 3 showed that PTSD was not associated with baseline frailty levels but showed a significant time interaction (B = 0.001, p = .008), indicating modest acceleration of frailty progression among affected veterans. Findings support positive social change through early sEDS screening and trauma-informed, nonpharmacologic sleep care to reduce frailty in veterans.
