On the Golden Rule of capital accumulation under endogenous longevity [PDF]

open access: yes
This note derives the Golden Rule of capital accumulation in a Chakraborty-type economy, i.e. a two-period OLG economy where longevity is endogenous. It is shown that the capital per worker maximizing steady-state consumption per head is inferior to the ...

Structural and Dynamic Properties of Lipid‐Coated Gold Nanoparticles

open access: yesAdvanced 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

UCST‐Driven Shape Morphing in Digital Light Processing 4D‐Printed Hydrogels

open access: yesAdvanced Materials Technologies, EarlyView.
A DLP‐printable UCST hydrogel based on poly(acrylic acid‐co‐acrylamide) enables reversible thermally induced expansion and 4D shape morphing. Rational control of composition, porosity, and multimaterial architecture enables predictable 4D shape morphing through differential swelling and localized actuation, opening new opportunities for high‐resolution
