Anatomical adaptations of the hind limb musculature of tree-kangaroos for arboreal locomotion (Marsupialia : Macropodinae) [PDF]

open access: yes, 2012
Tree-kangaroos (Dendrolagini) are Australasian marsupials that inhabit tropical forests of far north-eastern Queensland and New Guinea. The secondary adaptation of tree-kangaroos to an arboreal lifestyle from a terrestrial heritage offers an excellent ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

open access: yesAdvanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Molecular Rotors: From Newtonian Fluids to Functional Materials as Viscosity and Temperature Sensing Tools

open access: yesAdvanced Functional Materials, EarlyView.
Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.

Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational

3D Hydrodynamic Flow Lithography

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Walking and jogging at similar speeds with a passive SLIP model based compliant biped

open access: yesJournal of Biomechanical Science and Engineering
This paper studies a 2D, spring-loaded inverted pendulum (SLIP) passive dynamic biped with two degrees of freedom (stance leg only) to find the existence of symmetric periodic walking and jogging gaits.
