Charge‐Trapping Multilayer Electrets for Partial Discharge Mitigated AlN Substrates

Advanced Materials Interfaces, EarlyView.
Multilayer electret films deposited on AlN substrates trap injected charge and generate an opposing electric field at the triple point. Finite‐element simulation shows the retained charge reduces the local field by about one third. Under steep high‐voltage pulses, the charged stacks raise the partial discharge inception voltage and lower the discharge ...

GOLD plasma bubble observations comparison with geolocation of plasma irregularities by back propagation of the high-rate FORMOSA7/COSMIC 2 scintillation data

Frontiers in Astronomy and Space Sciences
Using the high-rate phase and amplitude scintillation data from FORMOSA7/COSMIC two mission and back-propagation method, we geolocate plasma irregularities that cause scintillations.

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Interaction of plasma drifts: A hypothesis for equatorial spread F occurrence

Journal of Space Weather and Space Climate
Studies on the generation mechanisms of post-sunset ionospheric irregularities, which constitute a threat to trans-ionospheric radio propagation, particularly at the African sector, are quite sparse.

Temperature-dependent bubble growth under synergistic interactions of hydrogen and helium in tungsten

Nuclear Fusion
A novel theoretical model based on modified diffusion rate equations is proposed to simulate the retention of hydrogen isotopes and the dynamics of bubble growth in tungsten (W) when exposed to simultaneous hydrogen (H) and helium (He) plasma ...

Bubble, Bubble, Where's the Housing Bubble? [PDF]

Discussions of whether a housing bubble exists generally rely on indirect barometers such as rapidly increasing prices, unrealistic expectations of future price increases, and rising ratios of housing price indexes to indexes of household income.

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

Advanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...
