Ultrasound‐Activated Bifunctional Piezoelectric Hydrogel Dressings Promote Infected Wound Healing via Regulating Angiogenesis and Lymphangiogenesis

Advanced Science, EarlyView.
This study developed a double‐network hydrogel with piezoelectric properties, exhibiting excellent antibacterial activity and promoting fibroblast migration, angiogenesis, and lymphangiogenesis through piezoelectric stimulation, thereby accelerating the healing of infected chronic wounds.

A Method for Along-Track Interferometric Phase Elimination of Large Baseline Imaging Radar Altimeter

IEEE Access
The large baseline imaging radar altimeter (LB-IRA), deployed in a dual-satellite formation, enhances altimetric accuracy to sub-centimeter levels through the use of helical orbits to extend the interferometric baseline.

Physical Sources of High‐Frequency Seismic Noise on Cascadia Initiative Ocean Bottom Seismometers

Geochemistry, Geophysics, Geosystems, 2020
Physical sources of high‐frequency seismic noise in the ocean are investigated using data from the Cascadia Initiative (CI) ocean bottom seismometer (OBS) network, hindcasts of wind speed, waves, and the bottom currents predicted by a regional ocean ...

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

The Winds and Currents Mission Concept

Frontiers in Marine Science, 2019
The Winds and Currents Mission (WaCM) is a proposed approach to meet the need identified by the NRC Decadal Survey for the simultaneous measurements of ocean vector winds and currents. WaCM features a Ka-band pencil-beam Doppler scatterometer able to map

Microstructure‐Resolved Modeling to Predicting and Regulating Lithium Plating‐Stripping Dynamics on Graphite Electrodes

Advanced Science, EarlyView.
ABSTRACT The lithium plating reaction in graphite electrodes acts as a root cause for the accelerated degradation and the internal short circuits in lithium‐ion batteries. Here, an electrochemical model based on multi‐scale microstructural images was established to identify lithium plating‐stripping processes, thereby supporting the predictive outcomes

Calculation of wind-driven surface currents in the North Atlantic Ocean [PDF]

Calculations to simulate the wind driven near surface currents of the North Atlantic Ocean are described. The primitive equations were integrated on a finite difference grid with a horizontal resolution of 2.5 deg in longitude and latitude.

An improved dual-frequency technique for the remote sensing of ocean currents and wave spectra [PDF]

, 1984
A two frequency microwave radar technique for the remote sensing of directional ocean wave spectra and surface currents is investigated. This technique is conceptually attractive because its operational physical principle involves a spatial ...
