An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring

open access: yesAdvanced Science, EarlyView.
Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...

Catalyst‐Free Collagen Filament Crosslinking for Engineering Anisotropic and Mechanically Robust Tissue Scaffolds

open access: yesAdvanced Science, EarlyView.
A bioorthogonal rhodamine/PEG crosslinking strategy is introduced to engineer dense collagen hydrogels with high mechanical resilience and cytocompatibility. Integration with wet‐spinning enables the fabrication of uniaxially aligned, cell‐laden collagen filaments that activate mechanotransductive signaling and support functional muscle regeneration in

Improved Similarity Law for Scaling Dynamic Responses of Stiffened Plates with Distorted Stiffener Configurations

open access: yesApplied Sciences
Experimental analysis on small-scale models is widely used to predict the dynamic responses of full-scale structures subjected to impact loads. However, due to manufacturing constraints, achieving a perfectly scaled model under a large scaling factor is ...

Development of a Degradation Model for the Collapse Analysis of Composite Aerospace Structures [PDF]

open access: yes, 2006
For stiffened structures in compression the most critical damage mechanism leading to structural collapse is delamination or adhesive disbonding between the skin and stiffener.

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

open access: yesAdvanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

GOT1 Inhibition Induces Extracellular Matrix Remodeling in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Using tumor tissue engineering, we recreated pancreatic cancer and found that inhibiting glutamic‐oxaloacetic transaminase 1 (GOT1) induces extracellular matrix remodeling and secretome rewiring, as well as promotes cell death. ABSTRACT Pancreatic cancer cells rely on glutamine to sustain their survival in the stiff and poorly vascularized tumor ...

Analyses of stiffened plates resting on the viscoelastic foundation subjected to a moving vehicle by a cell-based smoothed triangular plate element

open access: yesHo Chi Minh City Open University Journal of Science - Engineering and Technology, 2014
Recently, a cell-based smoothed discrete shear gap method (CS-FEM-DSG3) based on the firstorder shear deformation theory (FSDT) was proposed for static and free vibration analyses of Mindlin plates.

Effective Breadth of Stiffened Plate

open access: yesJournal of Zosen Kiokai, 1934
As a practical application of the method given in the preceding section, the author investigates the effective breadths in the following cases of plates with parallel sitiffeners, corresponding to the most usual ship structures, such as decks, shells and bulkheads etc., i.e.1.

Mechanical Overloading‐Induced Nanomineral Crystal Perturbation from the Osteochondral Interface: A Potential Initiator of Osteoarthritis

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...
