Abstract Bilayer graphene (BLG) is intriguing for its unique properties and potential applications in electronics, photonics, mechanics. However, the chemical vapor deposition synthesis of large-area high-quality bilayer on Cu suffering from a low growth rate limited coverage. Herein, we demonstrate fast meter-sized film commercial polycrystalline foils by introducing trace CO 2 during high-temperature growth. Continuous with high ratio AB-stacking structure can be obtained within 20 min,...
Metal-organic frameworks (MOFs) with controllable shapes and sizes exhibit tremendous potential in environmental remediation. However, the synergistic effects between shape photocatalytic performance have not been fully established. Herein, a...
Single-crystal graphene (SCG) wafers are needed to enable mass-electronics and optoelectronics owing their excellent properties compatibility with silicon-based technology. Controlled synthesis of high-quality SCG can be done exploiting single-crystal Cu(111) substrates as epitaxial growth recently. However, current films prepared by magnetron sputtering on sapphire still suffer from in-plane twin boundaries, which degrade the chemical vapor deposition. Here, it is shown how eliminate...
Bilayer graphene with an AB-stacking sequence has emerged as one of the promising materials owing to its unique band-gap structure and fascinating potential in electronic photonic applications. However, chemical vapor deposition growth bilayer on Cu substrates still suffers from limited coverage, poor uniformity, random distribution stacking order. Herein, we demonstrated efficient method synthesize centimeter-sized films a ratio over 80% space-confined substrates. Moreover, order...
Salt dissolution in shale increases pore connectivity, which helps improve the initial production of gas wells. In this study, soaking and imbibition experiments were carried out to simulate process rock coming into contact with hydraulic fracturing fluid. The results show that salt can promote release space communication pores within main size range 0.01–100 μm; number mesopores also increasing dissolution. rate salts increase specific surface area time. After dissolution, cation formed is...
Abstract The high-intactness and ultraclean fabrication of suspended 2D materials has always been a challenge due to their atomically thin nature. Here, we present universal polymer-free transfer approach for fabricating by using volatile micro-molecule cyclododecane as the medium, thus ensuring intact surface materials. For fabricated monolayer graphene, intactness reaches 99% size below 10 µm 36 µm. Owing advantages ultra-cleanness large size, thermal conductivity 4914...
