Structural and Dynamic Properties of Lipid‐Coated Gold Nanoparticles

Advanced Materials Interfaces, EarlyView.
Atomistic molecular dynamics simulations reveal how lipid chemistry governs the behavior of coatings on the surface of a gold nanoparticle. Variations in headgroup charge and acyl‐chain saturation produce distinct monolayer‐like lipid organization, ranging from compact, ordered coatings to extended, dynamic shells. These findings establish a foundation

Boosting lubrication and wear resistance by alkyl chain-dominated network design for balanced confinement effect in supramolecular gels

Nano Research
Supramolecular gelators can confine lubricating oils into gels and anchor them to the substrates, reducing friction and wear in mechanical engineering. However, excessive gel network confinement traps lubricants within gel clusters, hindering lubricant ...

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in
