Alcids-like flapping wing for exploring the role of wing folding in underwater locomotion. [PDF]

J R Soc Interface
Alcids showcase excellent aerial–aquatic locomotion abilities benefitting from the morphing wing. In the aerial environment, alcids fully extend their wings, while underwater, they partly fold the wings. In this article, we mimicked the wing morphology of the alcids family to explore the hydrodynamic advantage of the folded configuration in the aquatic

Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

Advanced Healthcare Materials, EarlyView.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Additive Manufacturing of Ordered Polymer Nanostructures

Advanced Materials, EarlyView.
A new 3D printing strategy, Polymerization‐Induced Arrangement of Nanostructures with Order‐tunability (PIANO), enables the formation of ordered nanostructures in polymer materials by enhancing chain mobility during photopolymerization, overcoming the kinetic arrest that leads to disordered morphologies in the conventional Polymerization‐Induced ...

ANALYSIS OF AIRCRAFTS LAYOUTS WITH FOLDED WINGS

Information systems, mechanics and control, 2014
For determination of the aerodynamic characteristics we used Panel-vortex method of symmetrical features which was implemented in the program PANSYM by TsAGI creation. The characteristics of a number of configurations with different relative wings consoles positions which differ by sweepback consoles and layouts of Box-wing and Joined-wing were ...

The Coupled Wing Morphing of Ornithopters Improves Attitude Control and Agile Flight

Machines
Bird wings are exquisite mechanisms integrated with multiple morphological deformation joints. The larger avian species are particularly adept at utilizing their wings’ flapping, folding, and twisting motions to control the wing angle and area.

Resolving Heterogeneity of Targeted Lipid Nanoparticles Through Solution‐Based Biophysical Analyses

Advanced Materials, EarlyView.
AF4‐UV‐DLS‐MALS‐SAXS resolves previously inaccessible targeted lipid nanoparticle (tLNP) subpopulations that differ in size, shape, and composition. Correlation of subpopulation‐resolved biophysical properties with in vivo RNA delivery reveals that targeted placental transfection is associated with distinct tLNP subpopulations rather than ensemble ...
