OCTOID: A Soft Robotic System Featuring Programmable Shape Morphing and Dynamic Structural Coloration

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by octopuses, actuating legs based on soft materials are fabricated with programmed chiroptical properties and mechanical behaviors to achieve dynamic color modulation and reversible shape morphing, and these legs are developed into a modular OCTOID system.

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

THE METHODOLOGY USED TO INTERPRET CUSTOMARY LAND TENURE

open access: yesPotchefstroom Electronic Law Journal, 2012
Customary land tenure is normally not based on codified or statutory sources, but stems from customary traditions and norms. When westernised courts have to interpret and adjudicate these customary traditions and norms, the normal rules of statutory ...

Controlled Movement of Soft Actuators using Multi‐Responsive Microgel Arrays and Microcirculatory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Microscale hydrogels (microgels) feature improved mass transport characteristics supportive of fast actuation and chemical tunability amenable to programmed stimuli response. A unique soft actuator architecture is realized by encapsulating microgels in soft microcirculatory systems which enable the convenient delivery of liquid stimuli for powering and

From Ethical Naturalism to Aquinas’ Notion of Natural Law: A Non-Trivial Convergence?

open access: yesReligions
Is it possible for Aquinas’s moral theology to engage constructively with contemporary moral naturalism? The proposed question has already been a subject of scholarly interest, eliciting various responses.

Hobbes and Selfish Morality in the State of Nature [PDF]

open access: yesIdeas y Valores, 2008
In this paper I explore the controversial claim that morality exists in the Hobbesian state of nature (represented in the rationality and prudence of natural laws), and how this moral is a necessary condition to achieve civil state.

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

open access: yesAdvanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.
