    Abstract Over the past decades, the design of active catalysts has been the subject of intense research efforts. However, there has been significantly less deliberate emphasis on rationally designing a catalyst system with a prolonged stability. A major obstacle comes from the ambiguity behind how catalyst degrades. Several degradation mechanisms are proposed in literature,   but with a lack of systematic studies, the causal relations between degradation and those proposed mechanisms remain ambiguous. Here, a systematic study of a catalyst system comprising of small particles and single atoms of Pt sandwiched between graphene layers, GR/Pt/GR, is studied to  unravel the degradation mechanism of the studied electrocatalyst for oxygen reduction reaction(ORR). Catalyst suffers from atomic dissolution under ORR harsh acidic and oxidizing operation voltages. Single atoms trapped in point defects within the top graphene layer on their way hopping through toward the surface of GR/Pt/GR architecture. Trapping mechanism renders individual Pt atoms as single atom catalyst sites catalyzing ORR for thousands of cycles before washed away in the electrolyte. The GR/Pt/GR catalysts also compare favorably to state-of-the-art commercial Pt/C catalysts and demonstrates a rational design of a hybrid nanoarchitecture with a prolonged stability for thousands of operation cycles.

    Abstract The functional microporous layer, acting as a mass-transfer control medium with a rational structure and surface morphology as well as high electrical conductivity, significantly affects the performance of micro-direct methanol fuel cells (μDMFCs). Bioinspired by the architecture and multi-functional properties of mangrove roots, this study develops a simple and versatile strategy based on magnetron sputtering and chemical vapor deposition to fabricate a mangrove root-inspired carbon nanotube film (MR-CNTF) as the functional interface in μDMFCs. It has features such as ultralightweight, high porosity, and good electrical conductivity. During the synthesis process, an apex-growth model of CNTF is identified. The results indicate that the MR-CNTF used as a cathodic microporous layer can remarkably facilitate the oxygen transport and water management. Because of its multi-functional structure and excellent material characteristics, the passive μDMFC displays a peak power density of 14.9 mW cm–² at 68 mA cm–². This value is 88.6% higher than the highest power density of the one based on a carbon nanotube array (7.9 mW cm–²) and 45% higher than that of the conventional carbon black (10.7 mW cm–²). We believe that this novel material with its multi-functional structure illuminates a promising application for fuel cells and other energy storage and conversion devices.

    Abstract The performance of protonic ceramic electrochemical cells (PCECs) is largely restricted by the slow oxygen reactions on the oxygen electrode. Herein, an active composite oxygen electrode Ba₀.₅Sr₀.₅Co₀.₇Fe₀.₂Ni₀.₁O₃₋δ–BaZr₀.₁Ce₀.₇Y₀.₁Yb₀.₁O₃₋δ (BSCFN–BZCYYb) with various mass ratios (6:4, 7:3, 8:2, and 9:1) is electrochemically investigated on fuel electrode-supported PCECs. BSCFN powder, with rich oxygen vacancies, shows a good chemical compatibility with BZCYYb electrolyte, as confirmed by the analyses of thermal gravimetric analysis and X-ray diffraction patterns. It is indicated that composite electrode with a ratio of 8:2 shows the best performance. For example, a peak power density (Pₘₐₓ) of 1.14 W cm–², an electrode polarization resistance (Rₚ) of 0.062 Ω cm², and a reasonable durability test of 24 h at −0.5A cm–² are delivered at 750 °C for the fuel cells with BSCFN–BZCYYb electrode with the ratio of 8:2. In addition, a stable operation (∼50 h) of cell with BSCFN–BZCYYb electrode (8:2 mass ratio) in dual modes of electrolysis and fuel cell (2 h for each mode) at ±0.5 A cm–² is obtained, demonstrating a good reversibility.

    Abstract Background: Biomarker changes that occur in the period between normal cognition and the diagnosis of sporadic Alzheimer's disease have not been extensively investigated in longitudinal studies.
    Methods: We conducted a multicenter, nested case-control study of Alzheimer's disease biomarkers in cognitively normal participants who were enrolled in the China Cognition and Aging Study from January 2000 through December 2020. A subgroup of these participants underwent testing of cerebrospinal fluid (CSF), cognitive assessments, and brain imaging at 2-year-to-3-year intervals. A total of 648 participants in whom Alzheimer's disease developed were matched with 648 participants who had normal cognition, and the temporal trajectories of CSF biochemical marker concentrations, cognitive testing, and imaging were analyzed in the two groups.
    Results: The median follow-up was 19.9 years (interquartile range, 19.5 to 20.2). CSF and imaging biomarkers in the Alzheimer's disease group diverged from those in the cognitively normal group at the following estimated number of years before diagnosis: amyloid-beta (Aβ)
    Conclusions: In this study involving Chinese participants during the 20 years preceding clinical diagnosis of sporadic Alzheimer's disease, we observed the time courses of CSF biomarkers, the times before diagnosis at which they diverged from the biomarkers from a matched group of participants who remained cognitively normal, and the temporal order in which the biomarkers became abnormal.
