Programmable Tensegrity‐Inspired Metamaterials With Compression–Torsion Coupling and Tunable Energy Dissipation

Songyu Zhang, Meiling Zhang, Qi Wen, Keyu Li et autres

ABSTRACT Mechanical metamaterials with programmable deformation, tunable energy dissipation, and reusable impact‐mitigation capability are highly desirable for adaptive protective systems and multifunctional mechanical devices. However, achieving stable compression–torsion coupling together with post‐fabrication programmability and recoverable energy dissipation remains challenging. Here, we develop …

Layered Lipid Nanoparticle Adjuvants Coordinate Toll-Like Receptor 4 and Toll-Like Receptor 9 Activation with Enhanced Immunity and Improved Tolerability

Haolin Chen, Ruifeng Wang, Zhihui Zhang, Zeyu Yang et autres

Vaccines rely on adjuvants to stimulate the immune system, but achieving strong immune activation together with acceptable tolerability remains a major challenge. Lipid nanoparticles are widely used as delivery platforms, yet how their internal organization can be engineered to coordinate multiple innate …

A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus

B.Q. Chen, Honghong Su, Shuanglei Li, Zhonghan Li et autres

Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome these limitations in a Ti50.5Zr40Nb6Sn2O1.5 alloy through Zr/O co-doping to …

Temporally Programmed H 2 O 2 and H 2 S-Releasing Hydrogel Dressing for Accelerated Infected Wound Healing

Yan Xu, Yanwei Du, Jingshi Liang, Xiaochu Ding et autres

Endogenous signaling molecules are essential for coordinated wound healing, yet current donor-based dressings typically provide only single-mediator delivery with limited release duration. Here, a multifunctional hydrogel dressing, HEVCTM, is developed by free radical copolymerization of N -hydroxyethyl acrylamide (HEAA) with a hydrogen …

A Lung-Targeted γδ T Cell Nanovaccine Couples Pulmonary Immune Priming to Systemic Antitumor Immunity in Non-Small-Cell Lung Cancer

Z L Yang, Liyan Li, Zepeng He, H H. Chen et autres

Non-Small-Cell Lung Cancer (NSCLC) often responds poorly to immune checkpoint blockade due to its immunosuppressive, “cold” tumor microenvironment. Activating alternative immune effectors may overcome this limitation. Here we identified lung-enriched γδ T cells as a key compartment in NSCLC and developed a …
