Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

Large-scale modular and uniformly thick origami-inspired adaptable and load-carrying structures

open access: yesNature Communications
Existing Civil Engineering structures have limited capability to adapt their configurations for new functions, non-stationary environments, or future reuse. Although origami principles provide capabilities of dense packaging and reconfiguration, existing

Reducing Personalization Time and Energy Cost While Walking Outdoors with a Portable Exosuit

open access: yesAdvanced Robotics Research, EarlyView.
Rapid Real‐World Optimization! An AF‐based human‐in‐the‐loop optimization strategy rapidly personalizes a portable hip extension exosuit for incline walking. Real‐time Bayesian optimization of assistive force significantly reduces metabolic energy—up to 16.2%—while converging in just 3 min 24 s.

Cut‐Enabled Mechanical Metamaterials for Multimodal and Reprogrammable Static Nonreciprocity

open access: yesAdvanced Science, EarlyView.
Cut‐enabled mechanical metamaterials are designed to overcome the challenge of obtaining multiple and reprogrammable static nonreciprocal modes in a single microstructural topology. It offers a pathway to synthesize multiple nonreciprocal modes and control the nonreciprocal responses, enhancing the functionality of metamaterials.

Nanomaterials Trigger Functional Anti‐Tumoral Responses in Primary Human Immune Cells

open access: yesAdvanced Science, EarlyView.
Nanoparticles are used to improve immunomodulatory therapies, but the impact of drug‐free nanomaterials on the immune system remains unknown. Screening common biomedical nanoparticles (NPs) reveals that PLGA NPs enhanced NK cell anti‐tumoral activity and transcriptional activation in human NK and pan T cells.
