AlScN/GaN Multichannel Heterostructures Grown by Metal–Organic Chemical Vapor Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Growth of AlScN/GaN multichannel heterostructures by metal–organic chemical vapor deposition is demonstrated for the first time. The growth of such structures is detailed through changes in growth parameters, such as the number of periods and the thickness of the channel layers, as well as structural studies.

PCSK9 Loss‐of‐Function Disrupts Cellular Microfilament Network via LIN28A/HES5/JMY Axis in Neural Tube Defects

open access: yesAdvanced Science, EarlyView.
PCSK9 acts as a molecular chaperone promoting LIN28A lysosomal degradation. LIN28A elevates transcription factor HES5, increasing JMY expression. PCSK9 loss causes neural tube defects (NTDs) by disrupting the LIN28A/HES5/JMY axis, and high JMY disorganizes the neural progenitor cell microfilament network, leading to incomplete neural tube structure in ...

Nanofluid‐Enhanced Laser Lithotripsy Using Conducting Polymer Nanoparticles

open access: yesAdvanced Science, EarlyView.
Incorporating polymeric nanoparticles, PEDOT:PSS, with a high near‐infrared absorption coefficient into the fluid significantly enhances the dusting efficiency of Ho:YAG laser lithotripsy for kidney stone treatment. This approach, which leverages the control of light‐matter interactions, integrates seamlessly with the current laser lithotripsy workflow.

Morphological Indicators of a Mascon Beneath Ceres's Largest Crater, Kerwan

open access: yesGeophysical Research Letters, 2018
Gravity data of Ceres returned by the National Aeronautics and Space Administration's Dawn spacecraft is consistent with a lower density crust of variable thickness overlying a higher density mantle. Crustal thickness variations can affect the long‐term,

El'gygytgyn impact crater, Chukotka, Arctic Russia: Impact cratering aspects of the 2009 ICDP drilling project

open access: yesMeteoritics and Planetary Science, 2013
The El'gygytgyn impact structure in Chukutka, Arctic Russia, is the only impact crater currently known on Earth that was formed in mostly acid volcanic rocks (mainly of rhyolitic, with some andesitic and dacitic, compositions).

A Thermally Stable Piezoresistive Textile for Reliable Tactile Sensing

open access: yesAdvanced Science, EarlyView.
A heat‐resistant piezoresistive textile based on silicon oxycarbide/carbon core–shell fibers is developed using scalable airflow‐assisted spinning. The textile retains tactile sensing performance at 250°C for 24 h and endures temperatures up to 495°C for 4 h.

Impact Flux on the Moon

open access: yesSpace: Science & Technology
The crust of the Moon records the complete history of collisions by different-sized projectiles from various sources since its early solidification. Planetary bodies in the inner Solar System experienced similar sources of impactors, and the Moon is an ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

open access: yesAdvanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought
