A tree-inspired liquid‐managing scaffold with radial-axial continuity for wound exudate management

Xiu-Juan Zhao, Zhao Pan, Lai-Xi Zhao, Zi-yi Shang et autres

Effective exudate management remains challenging in complex wounds because most dressings rely on local absorption or surface wetting, which readily fail under persistent, heterogeneous, and three-dimensional fluid input. Here, inspired by the radial–axial transport organization of trees, we developed an annealed bioinspired …

Evidence for magnetic order in the transverse field Ising magnet TmZn 2 GaO 5

Guangkai Zhang, Xubin Ye, Maocai Pi, Jie Zhang et autres

Abstract It has been theoretically predicted that the transverse-field Ising model on a triangular lattice undergoes two successive Berezinskii-Kosterlitz-Thouless (BKT) phase transitions into an ordered clock phase, separated by an intermediate quasi-long-range BKT phase. Experimentally, while this model has been realized in …

Disorder-tuned magnetism and magnetocaloric response in a layered SrGd2Al2O7 single crystal

Wenlong Yang, Guoliang Gong, Feifei Yuan, S. L. Tang et autres

We report the magnetic and magnetocaloric responses of SrGd 2 Al 2 O 7 single crystals, a Ruddlesden-Popper oxide that exhibits intrinsic A-site cation disorder. Structural analysis reveals significant Sr-Gd intermixing, which suppresses long-range magnetic order down to at least 2 K …

Negative Thermal Expansion in Metastable PbVO 3 : High‐Pressure Synthesis, Advances, and Perspectives

Zhao Pan, Takumi Nishikubo, Hajime Yamamoto, Xubin Ye et autres

ABSTRACT Most materials expand on heating; however, some materials show the opposite trend, in which the overall volume contracts upon heating, a phenomenon known as negative thermal expansion (NTE). Materials exhibiting NTE are highly valued for their unique ability to tailor thermal …

Characterization of large ferroelectric polarization and high- T C in sol–gel deposited PbTiO 3 -based perovskite thin films

Mengqi Ye, Zhao Pan, Weibin Song, Jin Liu et autres

Abstract Bi Me O 3 –PbTiO 3 (where Me represents transition metals) perovskite-type thin films have been widely studied due to their superior ferroelectric properties, including robust ferroelectric polarization and high Curie temperatures. In this study, PbTiO 3 -based perovskite thin films …

Achieving negative thermal expansion over an extended temperature range in rare‐earth‐modified PbTiO 3 ‐based perovskites

Zhao Pan, Meng-Qi Ye, Yan Suo, Fengyi Zhou et autres

Abstract Negative thermal expansion (NTE) is a notable physical property where a material’s volume decreases instead of increasing when heated. The identification of NTE materials is crucial for thermal expansion control engineering. Most NTE materials exhibit NTE only within a narrow temperature …

Realizing negative thermal expansion over an extended temperature range in PbTiO 3-based perovskites

Zhao Pan, Fengyi Zhou, Mengqi Ye, Duo Wang et autres

Negative thermal expansion (NTE) is fascinating as it involves a material’s volume contraction rather than expansion upon heating. Although NTE lattices typically have highly flexible frameworks, the magnitude of NTE is often very small, and they frequently behave a narrow temperature range …

High-temperature ferrimagnetic order triggered metal-to-insulator transition in CaCu3Ni2Os2O12

Xubin Ye, Yunyu Yin, Yingying Cao, Xiao Wang et autres

Ferromagnetic order-induced insulator-to-metal transitions via the double exchange mechanism have been studied widely. In contrast, ferromagnetic or ferrimagnetic spontaneous magnetization induced metal-to-insulator transitions (MITs), especially occurring above room temperature, remain extremely limited, although such magnetoelectric materials hold great potential for low-loss multifunctional …
