Modular 3D shape programming method for multiple substrates

Yizheng Tan, Yiheng Dai, Peng Zhao, Cheng Liu*, Huaping Xu* Matter; 2024, 7, 1117. Modular strategy is specialized in universality, compatibility, and simplicity. Although previous strategies still rely on highly customized processes, our research uses modular design to improve the simplicity and compatibility of shape programming. The module we used has a predefined hexagonal shape, which is mass-producible and can be transferred to a 2D substrate to produce controllable deformation in situ through nonpattern stimuli. This process can be finished in seconds due to the great responsiveness...

Polyurethane with β-Selenocarbonyl Structure Enabling the Combination of Plastic Degradation and Waste Upcycling

Chaowei He, Cheng Liu, Shuojiong Pan, Yizheng Tan, Jun Guan*, Huaping Xu* Angew. Chem. Int. Ed.; 2024, 68, e202317558. Degradable polymers offer a promising solution to mitigate global plastic pollution, but the degraded products often suffer from diminished value. Upcycling is a more sustainable approach to upgrade polymer waste into value-added products. Herein, we report a β-selenocarbonyl-containing polyurethane (SePU), which can be directly degraded under mild conditions into valuable selenium fertilizers for selenium-rich vegetable cultivation globally, enabling both plastic degradatio...

Selenium-Containing Nanocomplexes Achieve Dual Immune Checkpoint Blockade for NK Cell Reinvigoration

Banruo Xianyu, Shuojiong Pan, Shiqian Gao, Huaping Xu*, Tianyu Li* Small, 2023, 2306225. The blockade of immune checkpoints has emerged as a promising strategy for cancer immunotherapy. However, most of the current approaches focus on T cells, leaving natural killer (NK) cell-mediated therapeutic strategies rarely explored. Here, a selenium-containing nanocomplex is developed that acts as a dual immune checkpoint inhibitor to reinvigorate NK cell-based cancer immunotherapy. The Se nanocomplex can deliver and release siRNA that targets programmed death ligand-1 (PD-L1) in tumor cells, there...

Hyper-stable cholesteric heliconical architectures for monochromatic light separation

Yizheng Tan, Jun Guan, Huaping Xu* Matter; 2023, 6, 3121. A hyper-stable cholesteric heliconical superstructure has been achieved at room temperature through a simple strategy of mixing liquid crystal dimers. This breakthrough, recently reported in Matter by Li and colleagues, demonstrates an unprecedented and practical optic system for monochromatic light filtering important for various fields.

Extreme long-lifetime self-assembled monolayer for air-stable molecular junctions

Ningyue Chen, Shuwei Li, Peng Zhao, Ran Liu, Yu Xie, Jin-Liang Lin, Christian A. Nijhuis, Bingqian Xu, Liang Zhang*, Huaping Xu*, Yuan Li* Sci. Adv.; 2023, 9, eadh3412. The molecular electronic devices based on self-assembled monolayer (SAM) on metal surfaces demonstrate novel electronic functions for device minimization yet are unable to realize in practical applications, due to their instability against oxidation of the sulfur-metal bond. This paper describes an alternative to the thiolate anchoring group to form stable SAMs on gold by selenides anchoring group. Because of the formation of...
