One-Step Synthesis of Antioxidative Graphene-Wrapped Copper Nanoparticles on Flexible Substrates for Electronic and Electrocatalytic Applications
In
this study, we report a novel, one-step synthesis method to fabricate
multilayer graphene (MLG)-wrapped copper nanoparticles (CuNPs) directly
on various substrates (e.g., polyimide film (PI), carbon cloth (CC),
or Si wafer (Si)). The electrical resistivities of the pristine MLG-CuNPs/PI
and MLG-CuNPs/Si were measured 1.7 × 10<sup>–6</sup> and
1.4 × 10<sup>–6</sup> Ω·m, respectively, of
which both values are ∼100-fold lower than earlier reports.
The MLG shell could remarkably prevent the Cu nanocore from serious
damages after MLG-CuNPs being exposed to various harsh conditions.
Both MLG-CuNPs/PI and MLG-CuNPs/Si retained almost their conductivities
after ambient annealing at 150 °C. Furthermore, the flexible
MLG-CuNPs/PI exhibits excellent mechanical durability after 1000 bending
cycles. We also demonstrate that the MLG-CuNPs/PI can be used as promising
source-drain electrodes in fabricating flexible graphene-based field-effect
transistor (G-FET) devices. Finally, the MLG-CuNPs/CC was shown to
possess high performance and durability toward hydrogen evolution

Growth of Large-Area Graphene Single Crystals in Confined Reaction Space with Diffusion-Driven Chemical Vapor Deposition
To synthesize large-area graphene
single crystals, we specifically
designed a low-pressure chemical vapor deposition (LPCVD) reactor
with confined reaction space (L 22 mm × W 13 mm × H 50 μm).
Within the confined reaction space, a uniform distribution of reactant
concentrations, reduced substrate roughness, and the shift of growth
kinetics toward a diffusion-limited regime can be achieved, favoring
the preparation of large-area, high-quality graphene single crystals.
The gas flow field and mass transport pattern of reactants in the
LPCVD system simulated with a finite element method support the advantages
of using this confined reaction room for graphene growth. Using this
space-confined reactor together with the optimized synthesis parameters,
we obtained monolayer, highly uniform, and defect-free graphene single
crystals of up to ∼0.8 mm in diameter with the field-effect
mobility of μ<sub>EF</sub> ∼ 4800 cm<sup>2</sup> V<sup>–1</sup> s<sup>–1</sup> at room temperature. In addition,
structural design of the confined reaction space by adjusting the
reactor’s dimensions is of facile controllability and scalability,
which demonstrates the superiority and preference of this method for
industrial applications
The selection of the participants and the primary outcomes of the patients.
<p>The baseline renal functions (proteinuria) of all patients were determined within 3 years before cardiac arrest. <sup>a</sup>In total, 52 had diabetes-related proteinuria. OHCA: out-of-hospital cardiac arrest; ED: emergency department; DNR: do not resuscitate; ROSC: return of spontaneous circulation; CPC: cerebral performance categories.</p
Urine output is associated with survival.
<p>The urine output of the patients with a sustained ROSC (A) in the ED and (B) during the first 24 hours of the ICU stay (Spearman’s rank correlation test). Urine output was significantly increased in proportion to the magnitude of the fluid challenge (A) during ED resuscitation (p<0.001, r = 0.86) and (B) in the first 24 hours of the ICU stay in the patients who survived until discharge (p = 0.002, r = 0.81). However, in the patients who died during the hospital stay, (A) urine output did not significantly increase in proportion to the amount of fluid that was administered during the initial ED resuscitation period (B) but did increase during the first 24 hours of the ICU stay when the total fluid administered was ≤6000 ml. <sup>a</sup>The number of patients with missing urine output information.</p
The severity of proteinuria is associated with outcomes.
<p>The severity of proteinuria was significantly associated with (A) survival and (B) neurologic outcomes at the time of discharge (Chi-squared test). More severe proteinuria might indicate significantly poorer neurologic outcomes in survivors.</p
