Spatially-Encoding Hydrogels with DNA to Control Cell Signaling Adv. Mater. (IF 32.086) Pub Date : 2023-05-23 Namrata Ramani, C. Adrian Figg, Alex J. Anderson, Peter H. Winegar, EunBi Oh, Sasha B. Ebrahimi, Devleena Samanta, Chad A. Mirkin
Patterning biomolecules in synthetic hydrogels offers routes to visualize and learn how spatially-encoded cues modulate cell behavior (e.g., proliferation, differentiation, migration, apoptosis). However, investigating the role of multiple, spatially defined biochemical cues within a single hydrogel matrix remains challenging because of the limited number of orthogonal bioconjugation reactions available

Printable High-efficiency and Stable FAPbBr3 Perovskite Solar Cells for Multifunctional Building-integrated Photovoltaics Adv. Mater. (IF 32.086) Pub Date : 2023-05-23 Wang Yue, Hang Yang, Haoyu Cai, Yiming Xiong, Tao Zhou, Yongjun Liu, Juan Zhao, Fuzhi Huang, Yi-Bing Cheng, Jie Zhong
Perovskite solar cells (PSCs) show great promise for next-generation building-integrated photovoltaic (BIPV) applications because of their abundance of raw materials, adjustable transparency, and cost-effective printable processing. Owing to the complex perovskite nucleation and growth control, the fabrication of large-area perovskite films for high-performance printed PSCs is still under active investigation

Does Water-in-salt Electrolyte Subdue Issues of Zn Batteries? Adv. Mater. (IF 32.086) Pub Date : 2023-05-23 Ziyauddin Khan, Divyaratan Kumar, Xavier Crispin
Zn metal batteries (ZnBs) are safe and sustainable because of their operability in aqueous electrolytes, abundance and recyclability. However, the thermodynamic instability of Zn metal in aqueous electrolytes is a major bottleneck for its commercialisation. As such, Zn deposition (Zn2+ → Zn(s)) is continuously accompanied by hydrogen evolution reaction (HER) (2H+ → H2) and dendritic growth that further
