Three‐Dimensional Hierarchical Nanowire‐Networks with Deep‐Focus Tolerance and Adhesion Robustness for Harsh‐Environment SERS Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

open access: yesAdvanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...

1980—1981年院士制度在中国的筹备与搁浅 [PDF]

open access: yes, 2013
基于档案资料,考察了1980—1981年院士制度在中国的筹备经过与搁浅的原因及影响。这次院士制度的筹备导因于中国社会科学院院长、中央委员胡乔木的提议。筹备工作由中国科学院、中国社会科学院和国家科学技术委员会联合进行。1980年筹备期间,在胡乔木、方毅的推动下,经由钱三强、于光远、武衡等负责操办,形成《中国科学院、中国社会科学院院士条例(草案)》定稿和《关于建立院士制度问题的请示报告》。1980年10月21日,国务院常务会议同意了这3个单位上报的该请示报告。按照这次建立院士制度的计划 ...

Immune Predictors of Radiotherapy Outcomes in Cervical Cancer

open access: yesAdvanced Science, EarlyView.
This study reveals dynamic immune remodeling in cervical cancer following radiotherapy. Single‐cell analysis identifies the C3/C3AR1 axis as a central mediator of epithelial–myeloid crosstalk, whose inhibition reduces treatment efficacy in mice. Guided by these insights, the eight‐feature machine‐learning model: Cervical Cancer Radiotherapy Immune ...
