I am pleased to share that our article “𝐔𝐧𝐯𝐞𝐢𝐥𝐢𝐧𝐠 𝐭𝐡𝐞 𝐡𝐢𝐠𝐡 𝐜𝐚𝐩𝐚𝐜𝐢𝐭𝐢𝐯𝐞 𝐩𝐨𝐭𝐞𝐧𝐭𝐢𝐚𝐥 𝐨𝐟 𝐞𝐥𝐞𝐜𝐭𝐫𝐨𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥𝐥𝐲 𝐞𝐱𝐟𝐨𝐥𝐢𝐚𝐭𝐞𝐝 𝐬𝐮𝐩𝐞𝐫𝐢𝐨𝐫-𝐪𝐮𝐚𝐥𝐢𝐭𝐲 𝐛𝐢𝐥𝐚𝐲𝐞𝐫 𝐠𝐫𝐚𝐩𝐡𝐞𝐧𝐞" 𝐢𝐬 𝐧𝐨𝐰 𝐚𝐯𝐚𝐢𝐥𝐚𝐛𝐥𝐞 𝐨𝐧𝐥𝐢𝐧𝐞 𝐢𝐧 𝐭𝐡𝐞 𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥𝐬 𝐓𝐨𝐝𝐚𝐲 𝐂𝐡𝐞𝐦𝐢𝐬𝐭𝐫𝐲. Our bilayer graphene (BG) synthesis method surpasses the limitations of traditional liquid phase exfoliation by achieving: • 𝐋𝐚𝐲𝐞𝐫-𝐧𝐮𝐦𝐛𝐞𝐫 𝐌𝐨𝐧𝐨𝐝𝐢𝐬𝐩𝐞𝐫𝐬𝐢𝐭𝐲: We produce bilayer graphene (BG) with a 𝐜𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐭 𝐧𝐮𝐦𝐛𝐞𝐫 𝐨𝐟 𝐥𝐚𝐲𝐞𝐫𝐬, essential for high conductivity and a tunable bandgap, leading to reproducible performance in energy storage and electronic devices. • 𝐇𝐢𝐠𝐡 𝐎𝐩𝐭𝐢𝐜𝐚𝐥 𝐓𝐫𝐚𝐧𝐬𝐩𝐚𝐫𝐞𝐧𝐜𝐲: Our BG boasts exceptional transparency (∼𝟗𝟒.𝟖𝟕%), ideal for optoelectronic applications. • 𝐄𝐱𝐜𝐞𝐥𝐥𝐞𝐧𝐭 𝐂𝐨𝐧𝐝𝐮𝐜𝐭𝐢𝐯𝐢𝐭𝐲: The conductivity (∼𝟐.𝟑𝟗 × 𝟏𝟎⁶ 𝐒 𝐦⁻¹) rivals that of CVD-grown BG, a gold standard. Key to our success is the controlled exfoliation of 𝐬𝐢𝐧𝐠𝐥𝐞-𝐬𝐭𝐚𝐠𝐞 𝐈𝐈 𝐠𝐫𝐚𝐩𝐡𝐢𝐭𝐞 𝐛𝐢𝐬𝐮𝐥𝐟𝐚𝐭𝐞 (𝐆𝐁) – an intermediate 𝐞𝐥𝐞𝐜𝐭𝐫𝐨𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥𝐥𝐲 𝐞𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐞𝐝 for minimal defects and oxidation. Furthermore, the study explores the impact of oxygen content on the electrochemical performance of graphene. Our findings demonstrate a trade-off between specific capacitance and capacity retention: • 𝐋𝐨𝐰-𝐨𝐱𝐲𝐠𝐞𝐧 𝐁𝐆: Exhibits the highest capacity retention but lower capacitance. • 𝐇𝐢𝐠𝐡-𝐨𝐱𝐲𝐠𝐞𝐧 𝐆𝐎: Delivers superior capacitance but suffers from lower retention. This research paves the way for high-performance graphene-based supercapacitors with exceptional stability!

Key Points Demand for Carbon Nanotubes: #CarbonNanotubes (CNTs) are one-dimensional nanomaterials with excellent thermal, mechanical, and electromagnetic properties, making them highly sought after in fields such as carbon-based integrated circuits, super-strong and tough fibers, transparent conductive films, and flexible wearable devices. High-end applications demand stringent requirements for CNTs in terms of length, orientation, defect levels, and purity. Challenges in Growing Ultra-Long CNTs: Ultra-long CNTs, which follow a tip-growth mode, are essential for meeting these requirements and realizing the intrinsic superior properties of CNTs. However, the growth process involves the self-assembly of tens of billions of atoms under stringent conditions, leading to low yield and array density typically less than 50 tubes per mm, limiting application development. 3. New Method with Floating Bimetallic Catalysts (FBCs): Building on their previous strategy of substrate interception guidance, Zhang’s team proposed an in-situ gas-phase synthesis method using FBCs (Figure 1). They introduced ferrocene and acetylacetonate salts (as iron and secondary metal precursors) into the reactor. The diverse and easily sublimable nature of acetylacetonate salts facilitates the formation of new binary alloy floating catalysts. 4. Process Description: The precursors undergo sublimation, decomposition, and coalescence at the reactor inlet to form FBC nanoparticles, which are continuously introduced into the reactor with carrier gas. The carbon source decomposes on the FBC particles, growing CNTs floating in the gas phase. Substrate edges in the reactor intercept these floating CNTs, guiding their growth and significantly increasing the probability of “kite” mode growth. FeCu catalysts grown CNT horizontal arrays showed markedly improved yield, density, and uniformity compared to Fe catalysts. info@graphenerich.com More details: https://lnkd.in/grteyiCt

Thrilled to share that our latest collaborative research article, "Investigation of the physical properties through strain effect of monolayer silicon carbide material: DFT analysis," has been published in Physica B: Condensed Matter. In this work, Dr. Md. Rasidul Islam (BMSFMU), our first author Md. Mahfuzul Haque (my master's student), and I explore the fascinating physical properties of monolayer silicon carbide (SiC) under various strain conditions. Our DFT analysis reveals that SiC exhibits dynamic and mechanical stability across a range of strains, along with remarkable optical properties in the visible and IR regions. Notably, we found that SiC transitions from an indirect to a direct bandgap under tensile strain, underscoring its potential for advanced optoelectronic applications. 🌐 Read the full article here (open access until December 26, 2024):
