Observations of the Roots of Plasma Bubbles: Are they sometimes foamy?

Journal of Geophysical Research: Space Physics, 2023
Abstract Dramatic irregularities in the plasma density of the ionosphere, first discovered by their effects on radio wave propagation in 1938, despite decades of investigation, still remain puzzling. Their deleterious effects on radio wave communication, satellite command and control, and GPS navigation strongly motivate better ...

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Bubble evolution and fuzz formation in plasma-facing materials: from ridges to tendrils

Nuclear Fusion
Fuzz formation in plasma-facing materials remains insufficiently understood. We correlate subsurface helium-bubble evolution with surface morphological transitions in tungsten–rhenium (25 atomic %) exposed to high-flux, 90 eV He plasma at ∼1173 K ...

Inertially confined plasma in an imploding bubble [PDF]

Nature Physics, 2010
Theory predicts that the conditions generated by acoustic cavitation of a liquid could be enough to drive thermonuclear fusion. But convincing experimental evidence of this is lacking. New results now suggest that the conditions achieved are comparable to those produced in laser-driven fusion experiments.

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.
