Welcome to Xi an Jiaotong University School of Materials Science and Engineering
Ultra-high-strength metallic materials are urgently required in aerospace and defense applications, where weight reduction and extreme load-bearing performance are critically important. Developing advanced alloys that simultaneously achieve ultra-high yield strength (σy ≈ 2 GPa) and appreciable uniform elongation (εu > 5%) has therefore emerged as a key research focus. To date, only a limite...

To provide international students with a more intuitive understanding of the school'...
Atomic-scale manufacture is a critical technology required for future atomic-scale information devices. Among various techniques, scanning probe microscopy-based tip manipulation plays an essential role in atomic-scale manufacturing, enabling the construction and precise tuning of atomic structures with single-atom accuracy. For materials like graphene and other 2D materials, this technique all...
BackgroundThere is a significant demand for high-energy lithium-ion batteries (LIBs) with long cycle life, especially for electric vehicles. To achieve cell-level energy densities surpassing 400 Wh kg⁻¹, the ideal strategy is to pair high-voltage Ni-rich (NMC811) cathodes with silicon-majority-graphite (SmG, >1500 mAh g−1) anodes. Silicon offers a theoretical capacity far exceeding graphite, ...
Most engineering alloys are crystalline. When crystallization is bypassed by rapid quenching, the resulting alloy—though macroscopically indistinguishable from conventional metals—lacks long-range crystalline order (Fig. 1, left). A wide range of elements and combinations can form amorphous states, including elemental Ta and Au; binary, ternary, and multicomponent systems such as Ni–B, Cu–Z...
In aerospace, nuclear energy, and advanced manufacturing, structural materials must operate reliably from cryogenic to high temperatures. Conventional alloys face a persistent strength–ductility trade-off: strengthening typically comes at the expense of tensile elongation, and high-temperature strength degrades sharply. Refractory high-entropy alloys (RHEAs)—composed of high-melting elements ...
Under China’s “dual-carbon” goals, photovoltaic and wind power are becoming central to the energy mix, yet their intermittency and volatility impede large-scale grid integration. Aqueous organic redox flow batteries (AORFBs) are an attractive storage solution because of their low cost, intrinsic safety, and decoupled power/energy design. Among anolytes, viologen derivatives are widely used...
Photocatalysis is a promising approach for sustainable chemical synthesis, but its efficiency relies on precise control of electron transfer dynamics—a challenge that natural photosynthesis inspires but artificial systems struggle to replicate. While crystalline frameworks offer ordered structures for directing charge transport, their dense packing limits mass transport and light penetration. ...
A recent study has marked a significant breakthrough in atomic-scale simulations of phase-change memory (PCM) devices, providing a powerful theoretical tool for the research and design of next-generation memory devices and neuromorphic computing chips. The paper, titled “Full-cycle device-scale simulations of memory materials with a tailored atomic-cluster-expansion potential”, was published ...
