Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

open access: yesAdvanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Smoking and Health Investments: Impacts of Health Adaptation and Damage Reversibility [PDF]

open access: yes
In the present paper we examine how different sets of beliefs about the health effects of smoking would influence a rational smoker. By embedding the rational addiction theory in a Grossman model of health investment modified to take account of ...

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Rational Assent and Self–Reversion: A Neoplatonist Response to the Stoics [PDF]

open access: yes, 2016
This paper begins by arguing that, according to the Stoics, humans are accountable for assenting (and withholding assent) just because of the way in which the capacity for assent is reason-responsive. The paper then goes on to raise a question for this view.
