Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Height-dependent differential rotation of the solar atmosphere detected by CHASE

Nature Astronomy
Rotation is an intrinsic property of stars and provides essential constraints on their structure, formation, evolution and interaction with the interplanetary environment.

Periodic Change of Solar Differential Rotation [PDF]

The Astrophysical Journal, 2005
The periodic oscillation of the inhomogeneous rotation of the Sun is studied by use of the MHD dynamo theory. There exists a turbulent electromotive force that is driven by the vorticity of the flow (i.e., the γ dynamo). In addition, its counterpart exists in the vorticity equation, that is, the rotation is induced by an inhomogeneous magnetic field in

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts

Advanced Functional Materials, EarlyView.
The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...

Towards inertial-mode helioseismology: Direct sensing of solar rotation at 75° latitude and 0.8 R⊙

Astronomy & Astrophysics
Context. Because solar global inertial modes are highly sensitive to differential rotation, they may provide new diagnostics of internal rotation at high latitudes, where acoustic-mode helioseismology provides only weak constraints. Aims.

Rotating Turbulent Thermal Convection and Solar Differential Rotation

, 2023
The expansion of the rotating fluid will change the vorticity and rotational speed of the expanding region. In turbulent thermal convection, this microscopic effect is preserved.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

SoHO/EIT, Stereo-A, and SDO/AIA View for Solar Coronal Differential Rotation [PDF]

Iranian Journal of Astronomy and Astrophysics
Differential rotation of the solar corona is challenging due to the nature of short-wavelength emissions. In this study, we aim to measure coronal differential rotation from different perspectives using observations from SoHO/EIT at 195 Å, Stereo-A/EUVI ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Ray Tracing of MHD Rossby Waves in the Solar Tachocline: Meridional Propagation and Implications for the Solar Magnetic Activity

Frontiers in Astronomy and Space Sciences, 2022
Rossby waves have been recently recognised for their role in the large-scale spatio-temporal organisation of the solar magnetic activity. Here, we study the propagation of magnetohydrodynamic Rossby waves in a thin layer, representing the solar ...
