Trojaning the Alignment: Stealthy Backdoor Attacks against Graph Foundation Models

Minhua Lin, Zhicheng Gao, Yilong Wang, Hanqing Lu et autres

Graph Foundation Models (GFMs) on text-attributed graphs (TAGs) align graph representations with language semantics to support transferable graph learning. Despite these advantages, the backdoor vulnerability of GFMs on TAGs remains insufficiently understood, especially under graph-language alignment, where graph and text representations are …

Observation of bandgaps in multilayer silicon nanoribbons

Zhicheng Gao, D Li, Hui Zhou, Jisong Gao et autres

One-dimensional (1D) materials have attracted significant interest due to their unique quantum properties and potential applications in nanoscale devices. Pentagonal silicon nanoribbons (SiNRs), a prototypical 1D material, have been recently reported to host gapless Dirac fermions. However, for practical applications such as …

Synthesis of One- and Two-Dimensional Carbon Nitrides on Cu(111)

Yudian Zhou, Dong Li, Zhicheng Gao, Qiaoxiao Zhao et autres

Abstract Low-dimensional carbon nitrides are expected to exhibit rich structural diversity and tunable electronic properties; however, their controlled synthesis remains challenging. Here, we demonstrate the synthesis of one- and two-dimensional carbon nitride phases on Cu(111) using ion-beam-assisted epitaxy. By systematically tuning the …

Realization of Iodinene with Tunable Topological Edge States and Flat Bands

Dong Li, Yu Wang, Xinlei Zhao, Jisong Gao et autres

Halogens, known for their diatomic molecular structures, typically do not form extended covalent materials. The development of 2D elemental materials from halogens is therefore significant for both fundamental research and practical applications. Here, we report the realization of a monolayer iodine sheet, …

Synthesis of Monolayer Ice on a Hydrophobic Metal Surface

Qiaoxiao Zhao, Meiling Xu, Dong Li, Zhicheng Gao et autres

Understanding water-metal interactions is central to disciplines spanning catalysis, electrochemistry, and atmospheric science. Monolayer ice phases are well established on hydrophilic surfaces, where strong water-substrate interactions stabilize ordered hydrogen-bond networks. In contrast, their formation on hydrophobic metals has been deemed ther-modynamically unfavourable, …

Deep potential molecular dynamics study on the hydrogen bonding interactions and diffusion behavior of fluorine in wet-process phosphoric acid production

Kangming Wu, Xiumin Chen, Jie Zhou, Wei Liu et autres

). DPMD simulations further demonstrate that the evaporation-concentration process densifies the global HBN, increasing its connectivity and structural compactness. Collectively, it can be concluded that residual fluorine is immobilized by a dual constraint: strong localized H-bond interactions and global HBN confinement. This …

Evidence of a two-dimensional nitrogen crystalline structure on silver surfaces

Xuegao Hu, Zhicheng Gao, Hui Zhou, Daiyu Geng et autres

Nitrogen, the most abundant element in Earth’s atmosphere, exists as a diatomic gas under standard temperature and pressure. In the two-dimensional (2D) limit, atomically thin nitrogen, termed nitrogene, has been theoretically predicted to form crystalline materials with various polymorphic configurations, exhibiting diverse …
