<div style="text-align:center"><b>Two‑dimensional assembled membranes and selective ion transport</b></div><div><br /></div><div><font size="1">The interlayer‑confined space of two‑dimensional assembled membranes provides a unique platform for the directional and selective transport of substances. Through geometric modulation, low‑tortuosity ion migration can be induced in electrochemical reactions to boost reaction kinetics. Furthermore, by regulating the interlayer spacing and interlayer chemical environment of two‑dimensional membranes, selective transmembrane transport from molecules to monovalent ions can be further tuned. Based on the above mechanism, we have constructed a variety of two‑dimensional assembled membrane layers, which have demonstrated promising performance in surface modification of lithium‑ion battery anodes and high‑efficiency lithium extraction from salt lakes.</font></div>

<div style="text-align:center"><b>Molecular-thin bilayer carbon membranes for high-performance CO2 separation</b></div><div><br /></div><div><div><font size="1">Next-generation carbon capture relies on membrane materials that simultaneously achieve molecular-level thinness, precise nanopore control, and exceptional mechanical robustness, a longstanding trilemma in membrane science. Here, we report graphene–amorphous carbon (GAC) bilayer membranes that overcome this challenge via a graphene-guided polymer conversion approach. Leveraging a super‑spreading effect, we uniformly coat graphene with an ultrasmooth, polymer‑derived carbon layer as thin as 2 nm, yielding outstanding mechanical strength with a Young’s modulus around 26.8 GPa. Meanwhile, controlled pyrolysis of the polymer precursor on graphene generates a carbon network containing high‑precision, narrowly distributed ultramicropores, as confirmed by atomic‑resolution electron microscopy. The resulting GAC membranes exhibit sharp molecular sieving (CO2/N2 &gt; 60, H2/CO2&gt; 70, CO2/CH4 &gt; 70) alongside exceptionally high CO2 permeance up to 5000 GPU, surpassing the state-of-the-art membranes. This combination of normally conflicting properties enables highly efficient carbon capture from flue gas, syngas, and natural gas streams, establishing GAC membranes as a versatile and energy‑efficient platform for sustainable molecular separations.</font></div></div>

<div style="text-align:center"><b>Yunting graphene Chip Interconnection and Displacement Sensing System</b></div><div><br /></div><div><div><font size="1">Graphene-based chip interconnect materials, characterized by their compact size, ultra-low resistivity, and high thermal stability, help overcome computational bottlenecks in 5G communications and AI chips. Graphene capacitive displacement sensors are being used in industrial applications—such as semiconductor equipment and precision machine tools—to replace imported products, thereby breaking foreign technological monopolies. </font></div><div><font size="1">1. Graphene is compatible with standard lithography processes; it can be fabricated into self-supporting thin films or beam structures at the atomic scale. As an interconnect conductor, graphene's cross-sectional area is 10⁻³ times smaller than that of copper, enabling interconnect and via dimensions to be maintained within the range of approximately 5–10 nm. By adjusting the angle between two graphene layers, the electric field can be altered, causing the bilayer graphene to transition into a superconductor. The British academic journal Nature published two consecutive articles detailing a groundbreaking discovery by Cao Yuan, a student from the USTC Young Talent Program, regarding graphene superconductivity: when two layers of parallel graphene are stacked at a subtle angle of approximately 1.08°, a superconducting effect is induced. This achievement is hailed as the "fifth great invention" in the world. </font></div><div><font size="1">2. The electron mobility of graphene (up to 2×10⁵ cm²/V·s) is significantly higher than that of copper (approximately 0.003 cm²/V·s), which can substantially reduce resistance and signal delay, making it ideal for high-frequency, high-density integrated circuits. Thermal management breakthrough: The thermal conductivity of graphene (5000 W/m·K) is more than 10 times greater than that of copper, enabling the resolution of thermal management challenges in chips fabricated using processes below 3 nm, thereby extending device lifespan and improving reliability. Beam structure: This enables the formation of self-supporting thin films or beam structures at the atomic scale. The nanoscale thickness of graphene helps mitigate edge effects and enhances the accuracy of surface roughness measurement and thin-film thickness determination. Graphene-based piezoresistive sensors can now detect surface fluctuations at the single-atom level, providing critical data for quantum computing research. The multi-parameter response characteristics of graphene enable the simultaneous monitoring of displacement and other physical quantities, allowing for the real-time generation of 3D pressure distribution maps of object surfaces and facilitating slip-free robotic grasping.</font></div><div><br /></div></div>
