  • Deformation behaviors of dislocation cellular structures in alloys produced by additive manufacturing
    Jinqiao Liu, Hao Wang, Ranming Niu, Chuanxi Ren, Kevin Sisco, Ying Liu, Zibin Chen, Julie Cairney, Yiu-Wing Mai, Simon Ringer, Xiaozhou Liao
    Materials Today, 2026
    • Additive manufacturing produces two distinct types of dislocation cell walls. • Different types of cell walls exhibit contrasting deformation behaviours. • Cell-wall fractions can be tuned by varying additive manufacturing parameters. • Improved mechanical properties are achieved by adjusting the cell-wall fractions. The dislocation cellular structure is a typical microstructural feature in additively manufactured alloys. A persistent debate surrounds how dislocation cellular structures strengthen materials. This study, utilizing in-situ tensile straining transmission electron microscopy, unveils the presence of two distinct types of cell walls, differentiated by the presence or absence of discernible crystallographic misorientations across the cell walls. Cell walls with misorientations act as dislocation sinks and absorb dislocations, whereas cell walls without misorientation hamper dislocation motion by forest dislocation entanglement. These contrasting cell wall–dislocation interaction mechanisms lead to different structural stabilities of cell walls. Cell walls with misorientations tend to maintain their structural integrity during deformation, while cell walls without misorientation are prone to dissolution under high strain. These deformation behaviors suggest that the dislocation cellular structure enforces both dislocation hardening and boundary hardening mechanisms, contingent on the type of dislocation cell walls. This study further demonstrates that by varying additive manufacturing parameters, the fractions of different types of cell walls can be adjusted, thereby enhancing the overall mechanical properties.
  • Effects of twinning configurations on the mechanical performance of small-scale FCC metallic materials
    Jinqiao Liu, Ranming Niu, Ji Gu, Ying Liu, Song Ni, Julie Cairney, Min Song, Yiu-Wing Mai, Ting Zhu, Xiaozhou Liao
    Acta Materialia, 2026
    The increasing demand for high-performance miniaturised devices has sparked extensive interest in enhancing the mechanical properties of micro- and nano-sized materials. Deformation twinning, a fundamental mechanism known for enabling strength–ductility synergy in bulk materials, has emerged as a potential strengthening strategy for small-scale systems. However, the relationship between twinning behaviour and the mechanical performance of small-sized materials remains poorly understood. This study employs quantitative in-situ tensile straining transmission electron microscopy combined with comprehensive microstructural characterisation to investigate the effects of three critical aspects of twinning behaviour on mechanical performance in small-sized face-centred cubic metallic materials: twin density, twin–twin interactions, and modes of twin boundary motion. The findings reveal that: (1) increasing twin density improves ductility of small-sized samples, but this effect hinges on the absence of stress-concentration sites; (2) twin–twin interactions, caused by their intersecting behaviour, induce stress concentration and promote necking, resulting in a distinct fracture mechanism compared to single-system twinning; and (3) twin-boundary sliding, in contrast to twin-boundary migration, leads to highly localised deformation, pronounced softening, and significantly reduced ductility. These results provide important insights into the structural design of small-sized single-crystalline materials where twinning-induced plasticity is a dominant deformation mechanism.

  • Enhanced Ammonia Electrosynthesis via In-Plane Integration of Fe2O3Dual-Phase Nanodomains
    Sandra Elizabeth Saji, Kaili Liu, Ying Liu, Zhehao Sun, Yi-Lun Chen, Hang Yin, Chengjun Dong, Xiaozhou Liao, Zongyou Yin
    ACS Applied Materials and Interfaces, 2025
    Iron oxides are notable among oxide semiconductors for their abundance and environmental friendliness, positioning Fe2O3 as a promising candidate for industrial nanotechnology. However, polymorphic Fe2O3 presents up to four phases, posing significant challenges in customizing them for nanocatalysis, including tasking a single phase with complex catalytic reactions, harnessing synergistic advantages during phase integration, and achieving selective reactivity amidst competing side reactions. Here, we developed a 2D-templated Z-direction-confining strategy combined with dual-phase nanocrystallization to synthesize thin-layered Fe2O3 with an in-plane nanoscale integration of α- and γ-phases. The resulting dual-phase Fe2O3 achieved superior electrochemical nitrate reduction to ammonia, yielding 4329.8 μg/mgcat/h at −0.8 V vs a reversible hydrogen electrode with high faradaic efficiency (∼95.7%) and outstanding selectivity (99.9%). Combined computational and experimental studies revealed that the enhanced performance arises from the synergistic integration of electron transport through the γ phase and active sites within the α phase, facilitated by ultrafine nanophase domains. Electrons reaching the α phase selectively drive nitrate reduction over proton reduction. The electrocatalyst exhibited exceptional stability across 28 cycles. This catalyst, with its high yield, faradaic efficiency, selectivity, stability, and low cost, outperforms previous catalysts under comparable conditions, highlighting the potential of nanophase manipulation for sustainable ammonia electrosynthesis from nitrate waste.

    Nano Energy, 2025
    The photocatalytic reduction of CO 2 to CH 4 offers a promising path for sustainable energy conversion, but its complexity, requiring an eight-electron transfer, poses significant challenges. This study presents a novel method to enhance the activity and selectivity of this reaction using Ag nanoparticles as cocatalysts on a mesoporous perovskite semiconductor, NiTiO 3 . By leveraging the synergistic effects of localized surface plasmon resonance (LSPR) and strategically engineered vacancies, the Ag-NiTiO3 catalyst achieves a 15-fold increase in CH 4 production and near-perfect selectivity, up from 92.4 % in pristine NiTiO 3 . Advanced simulations, including finite-difference time-domain (FDTD) and density functional theory (DFT), highlight the crucial role of LSPR-induced local electric fields and vacancies in enhancing methane selectivity. The integration of Ag nanoparticles into the NiTiO 3 matrix not only facilitates efficient electron-hole separation but also promotes the formation of vacancies essential for the CO 2 to CH 4 conversion. This work offers profound insights into the interaction between light, plasmonic materials, and semiconductor properties, providing a robust platform for optimizing photocatalytic performance. These findings advance our understanding of photocatalytic CO 2 reduction mechanisms, paving the way for designing more efficient and selective photocatalysts, contributing to broader CO 2 utilization strategies and addressing global carbon emissions and energy challenges. • Plasmon-Enhanced Photocatalysis: Ag-NiTiO 3 catalyzes the reduction of CO 2 via localized surface plasmon resonance effect. • Vacancy Engineering Synergy: Oxygen vacancies significantly boosting catalytic efficiency and methane production. • Mechanistic Insights via Simulations: FDTD and DFT analyses reveal the synergistic of LSPR effect and vacancies. • Exceptional Performance and Scalability: Chemical reduction method achieves higher CH 4 production and selectivity.
  • Ferroelectric Translational Boundaries Separating Antiferroelectric Domains in Y-Doped HfO2
    Ying Liu, Xianghan Xu, Fei-Ting Huang, Ranming Niu, Jinqiao Liu, Julie M. Cairney, Sang-Wook Cheong, Xiaozhou Liao
    ACS Applied Electronic Materials, 2024
    Domain walls in complex perovskite oxides are known for their unique functional properties and potential in electronic devices. Hafnium oxide (HfO 2 )-based ferroelectric and antiferroelectric materials, as a simpler transition-metal oxide system compared to perovskite-derived complex oxides, have gained significant interest due to their compatibility with silicon electronics and their lead-free composition, aligning with sustainable development goals. Nevertheless, research into the functionalities and structural characteristics of domain walls in hafnia is still limited, limiting their applications in domain wall electronic devices. In this work, using aberration-corrected scanning transmission electron microscopy high-angle annular dark field and integrated differential phase contrast imaging techniques, we revealed three types of translational boundaries (TBs), two with a phase difference of π and another one with a phase difference of π/2. The π TBs (or antiphase boundaries) show either a ferroelectric phase structure with a 0↑0↑ dipole pattern or a monoclinic phase structure, while the π/2 TB shows a reduced dipole magnitude. The ferroelectric TB is anticipated to enhance residual polarization within the polarization–electric field hysteresis loop. Its reversible switching capability indicates significant potential for implementation in domain wall memory devices, which are projected to be more energy efficient than traditional ferroelectric domain memories.
  • Coexistence of ferroelectric and ferrielectric phases in ultrathin antiferroelectric PbZrO3 thin films
    Ying Liu, Ranming Niu, Roger Uriach, David Pesquera, José Manuel Caicedo Roque, José Santiso, Julie M. Cairney, Xiaozhou Liao, Jordi Arbiol, Gustau Catalan
    Microstructures, 2024
    Whereas ferroelectricity may vanish in ultra-thin ferroelectric films, it is expected to emerge in ultra-thin antiferroelectric films, sparking people’s interest in using antiferroelectric materials as an alternative to ferroelectric ones for high-density data storage applications. Lead Zirconate (PbZrO3, PZO) is considered the prototype material for antiferroelectricity, and indeed, previous studies indicated that nanoscale PZO films exhibit ferroelectricity. The understanding of such phenomena from the microstructure aspect is crucial but still lacking. In this study, we fabricated a PZO film with thicknesses varying from 5 to 80 nm. Using Piezoresponse Force Microscopy, we discovered that the film displayed a transition from antiferroelectric behavior in the thicker areas to ferroelectric behavior in the thinner ones, with a critical thickness between 10 and 15 nm. In this critical thickness range, a 12 nm PZO thin film was chosen for further study using aberration-corrected scanning transmission electron microscopy. The investigation showed that the film comprises both ferroelectric and ferrielectric phases. The ferroelectric phase is characterized by polarization along the [011]pc projection direction. The positions of Pb, Zr, and O were determined using the integrated differential phase contrast method. This allowed us to ascertain that the ferroelectric PZO unit cell is half the size of that in the antiferroelectric phase on the ab plane. The observed unit cell is different from the electric field-induced ferroelectric rhombohedral phases. Additionally, we identified a ferrielectric phase with a unique up-up-zero-zero (↑↑··) dipole configuration. The finding is crucial for understanding the performance of ultrathin antiferroelectric thin films and the subsequent design and development of antiferroelectric devices.
  • Switching Dynamics and Improved Efficiency of Free-Standing Antiferroelectric Capacitors
    Umair Saeed, David Pesquera, Ying Liu, Ignasi Fina, Saptam Ganguly, José Santiso, Jessica Padilla‐Pantoja, José Manuel Caicedo Roque, Xiaozhou Liao, Gustau Catalan
    Advanced Electronic Materials, 2024
    The switching dynamics of antiferroelectric lead zirconate (PbZrO3) freestanding capacitors compared to their epitaxial counterparts is reported. Frequency dependence of hysteresis indicates that freestanding capacitors exhibit a lower dispersion of switching fields, lower residual polarization, and faster switching response as compared to epitaxially‐clamped capacitors. As a consequence, freestanding capacitor membranes exhibit better energy storage density and efficiency.
  • Room-temperature super-elongation in high-entropy alloy nanopillars
    Qian Zhang, Ranming Niu, Ying Liu, Jiaxi Jiang, Fan Xu, Xuan Zhang, Julie M. Cairney, Xianghai An, Xiaozhou Liao, Huajian Gao, Xiaoyan Li
    Nature Communications, 2023
    Nanoscale small-volume metallic materials typically exhibit high strengths but often suffer from a lack of tensile ductility due to undesirable premature failure. Here, we report unusual room-temperature uniform elongation up to ~110% at a high flow stress of 0.6–1.0 GPa in single-crystalline <110>-oriented CoCrFeNi high-entropy alloy nanopillars with well-defined geometries. By combining high-resolution microscopy and large-scale atomistic simulations, we reveal that this ultrahigh uniform tensile ductility is attributed to spatial and synergistic coordination of deformation twinning and dislocation slip, which effectively promote deformation delocalization and delay necking failure. These joint and/or sequential activations of the underlying displacive deformation mechanisms originate from chemical compositional heterogeneities at the atomic level and resulting wide variations in generalized stacking fault energy and associated dislocation activities. Our work provides mechanistic insights into superplastic deformations of multiple-principal element alloys at the nanoscale and opens routes for designing nanodevices with high mechanical reliability.
