Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

open access: yes, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

Locating the Cambrian Suture in Wilkes Land, East Antarctica, Based on Russian Geophysical Data

open access: yesRussian Journal of Earth Sciences
Interpretation of modern aeromagnetic and radar data, primarily from Russian surveys in East Antarctica between 88°–102°E, has resulted in a tectonic map of Precambrian provinces, including two protocratonic domains and two orogens of different ages. The

Environmental and climate changes in Antarctica in the Geological Past

open access: yesЛëд и снег, 2015
In the Cretaceous time, Antarctica was characterized by subtropical and tropical climate. The Early Eocene was warmest in the Antarctic history but this Climatic Optimum terminated with a long-term cooling trend that culminated in continental-scale ...

Pulsed Electrolysis Prevents Sulfur Poisoning for Sustained Sulfide Valorization

open access: yesAdvanced Materials, EarlyView.
Integrating pulsed electrolysis with Sc‐doped NiFe‐LDH enables sustainable sulfide valorization, achieving >500 h stability, 99.8% efficiency. Moreover, this technology produces high‐purity sulfur and sodium formate, boosting profit by 121% to $1,294.7 per tonne of hydrogen.
