NbN Broadband Plasmonic Absorbers for Efficient Hot‐Carrier Injection Toward Improved Solar‐to‐Hydrogen Conversion

open access: yesAdvanced Science, EarlyView.
Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

Experimental research on bonding mechanical performance of the interface between cementitious layers

open access: yesScience and Engineering of Composite Materials
Interfaces of cementitious layers have widely existed in construction projects, and they are the weakest part of the whole building. In this article, laser scanning and ultrasonic pulse, splitting tensile, and semi-disc fracture tests were carried out to

Arrayed Magnetic Accelerator Synergistically Enhances Orthodontic Tooth Movement via Microtubule Assembly‐Mediated Periodontal Remodeling

open access: yesAdvanced Science, EarlyView.
Mechanical orthodontic treatment for malocclusion is limited by slow remodeling and risks due to poor biomechanical sensing. This study shows that static magnetic fields (SMFs) enhance mechanical sensation in periodontal ligament cells, promoting inflammation and osteoclast activity.

Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

open access: yesAdvanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

open access: yesAdvanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Mechanically Robust, Self‐Healable, and Cryotolerant GelMA Hydrogel for Wearable Tactile Sensors with Enhanced Durability, Lifetime, and Environmental Stability

open access: yesAdvanced Science, EarlyView.
A mechanically robust, self‐healable, moisturizing, cryotolerant and adhesive GelMA hydrogel is developed by incorporating polyvinyl alcohol, acrylic acid, sodium tetraborate, and glycerol into GelMA matrix via a photoinitiated polymerization process. The hydrogel‐derived omni‐healable ionotronic pressure sensor can sensitively and consistently monitor

Service: IGEO Ultrasonic pulse velocity (UPV)

open access: yes
The method is based on the propagation of a high frequency sound wave (20 kHz - 500 kHz) through the stone material. The waves are introduced into the surface by a transducer coupled to the surface with a gel and received by a similar transducer coupled ...

Mechanophore‐Based Multichannel Colorimetric Force Sensors: Ultrasound‐Driven Stress and Strain Quantification

open access: yesAdvanced Science, EarlyView.
ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
