Isolation Techniques of Micro/Nano‐Scaled Species for Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Separating micro/nano‐scale bioparticles from samples is essential for disease diagnosis, prevention, and monitoring. Therefore, a comprehensive overview of the latest advanced separation technologies is provided, and characteristics and limitations based on six key performance parameters, including purity, recovery rate, throughput, resolution, size ...

Holistic Optimization toward Ultrathin Flexible Perovskite Solar Cells with High Efficiency and Mechanical Robustness

open access: yesAdvanced Science, EarlyView.
In this manuscript, 2D perovskite grain boundaries are constructed to improve the intrinsic flexibility of perovskite films by efficiently releasing the strain. In addition, a novel additive, sucralose, is employed to enhance the conductivity and mechanical flexibility of PEDOT:PSS electrodes. Consequently, an ultrathin f‐PSC is successfully fabricated

Natural Crystal Structure for Generating Raman‐Like Orbital Angular Momentum States

open access: yesAdvanced Science, EarlyView.
This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route

Large Built‐in Fields and Tunable Ferroelectricity in Composition‐Graded ScAlN Thin Films Deposited by Reactive Sputtering

open access: yesAdvanced Science, EarlyView.
This study explores composition‐graded ScxAl1‐xN thin films grown by large‐scale and CMOS‐compatible sputtering that can effectively suppress abnormally‐oriented grains. Importantly, their ferroelectric properties can also be tuned owing to large built‐in fields induced by chemical/polarization gradient.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

open access: yesAdvanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Achieving High Damping Capacity in Oxygen‐Enhanced BCC Zr‐Hf‐Ti‐Nb Multi‐Principal‐Element Alloys with Low Young's Modulus

open access: yesAdvanced Science, EarlyView.
A series of oxygen‐enhanced Zr‐Hf‐Ti‐Nb MPEAs with high strength and outstanding damping capacity are developed through tailoring the BCC structural stability by an elaborate composition regulation. Strengthening mechanism for high strength and damping mechanism related to various Snoek‐type relaxations reveals that the existence of multiple separate O‐
