We demonstrated a satisfactory diagnostic performance with a favorable safety profile of surgical lung biopsy in the diagnosis of suspected interstitial lung diseases. Surgical lung biopsy is especially recommended in patients with clinical information indicative but atypical of idiopathic pulmonary fibrosis, whereas the benefit of surgical lung biopsy should be carefully balanced against the risk for patients with immunocompromised status, mechanical ventilation dependence, or severe respiratory dysfunction.
γ‐Graphyne is a new nanostructured carbon material with large theoretical Li+ storage due to its unique large conjugate rings, which makes it a potential anode for high‐capacity lithium‐ion batteries (LIBs). In this work, γ‐graphyne‐based high‐capacity LIBs are demonstrated experimentally. γ‐Graphyne is synthesized through mechanochemical and calcination processes by using CaC2 and C6Br6. Brunauer–Emmett–Teller, atomic force microscopy, X‐ray photoelectron spectroscopy, solid‐state 13C NMR and Raman spectra are conducted to confirm its morphology and chemical structure. The sample presents 2D mesoporous structure and is exactly composed of sp and sp2‐hybridized carbon atoms as the γ‐graphyne structure. The electrode shows high Li+ storage (1104.5 mAh g−1 at 100 mA g−1) and rate capability (435.1 mAh g−1 at 5 A g−1). The capacity retention can be up to 948.6 (200 mA g−1 for 350 cycles) and 730.4 mAh g−1 (1 A g−1 for 600 cycles), respectively. These excellent electrochemical performances are ascribed to the mesoporous architecture, large conjugate rings, enlarged interplanar distance, and high structural integrity for fast Li+ diffusion and improved cycling stability in γ‐graphyne. This work provides an environmentally benign and cost‐effective mechanochemical method to synthesize γ‐graphyne and demonstrates its superior Li+ storage experimentally.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
