Supporting a Healthy Ocean: The Far-reaching Benefits of Large, Fully Protected Areas [PDF]

, 2015
The ocean covers nearly three-quarters of the planet and plays an essential role in supporting life on Earth. Its waters help regulate global chemistry and climate, and are home to over 2 million species, many of which still await discovery.1 This rich ...

Ultrafast, High‐Capacity Uranium Harvesting From Seawater via a Hierarchically Porous Polymer Electrode

Advanced Science, EarlyView.
A hierarchically porous AOPIM‐CNT electrode enables uranium harvesting from seawater via adsorption‐promoted electrodeposition. Rapid diffusion and selective adsorption are coupled with electrochemical crystallization and spontaneous detachment, creating a self‐refreshing process that sustains high‐capacity, continuous extraction from ultradilute ...

Heterointerface Engineering of Bismuth Nanosheets/Nitrogen‐Doped Carbon Nanoleaves Enables High‑Performance Electrochemical Dechlorination

Advanced Science, EarlyView.
Bismuth nanosheets integrated with nitrogen‐doped carbon nanoleaves are constructed via a 2D‐on‐2D heterointerface engineering strategy. The resulting BiNS/NCL electrode delivers high chloride adsorption capacity, fast kinetics, and stable cyclability. A built‐in electric field at the heterointerface promotes chloride electrosorption and stabilizes the

SOUTHERN OCEAN CURRENTS AND RECURVATURE CURRENT

Antarctic Record, 1963
Of the surface ocean currents in the Antarctic seas, there are found the eastward-flowing current running east in the water Lat. 50°-60°S and the westward-flowing current more or less circling Antarctica in the water. South of Lat. 60°S, the latter being

Simulation of Ocean Responses to an Idealized Landfalling Tropical Cyclone Using a Coupled Atmosphere-Wave-Ocean Modeling System

Tropical Cyclone Research and Review, 2012
: Oceanic responses to a hypothetical landfalling tropical cyclone (TC) are studied by using a coupled atmosphere-wave-ocean modeling system (CAWOMS). A set of experiments are conducted to compare the effects of atmosphere-wave-ocean interaction on ocean

A Universal Approach to Enhancing Silicon Hot‐Carrier Photodetectors for CMOS‐Compatible SWIR Imaging

Advanced Science, EarlyView.
Silicon hot‐carrier photodetectors offer a CMOS‐compatible pathway for SWIR detection but suffer from intrinsically low quantum efficiency. Here, we introduce a quasi‐generalized antireflection coating (QARC) that universally enhances optical absorption and quantum efficiency, enabling the first CMOS‐compatible SWIR imaging with silicon hot‐carrier ...
