High-Resolution Wind Measurements for Offshore Wind Energy Development

A mathematical transform, called the Rosette Transform, together with a new method, called the Dense Sampling Method, have been developed. The Rosette Transform is invented to apply to both the mean part and the fluctuating part of a targeted radar signature using the Dense Sampling Method to construct the data in a high-resolution grid at 1-km posting for wind measurements over water surfaces such as oceans or lakes.

Measuring Air-Sea Exchange of Carbon Dioxide in the Open Ocean

A team led by scientists at the National Oceanography Centre of Southampton, UK have measured the air-sea exchange of carbon dioxide in the open ocean at the highest wind speed to date. Their findings are important for understanding how interactions between the ocean and the atmosphere influence climate.

Desalinate Water, Produce Hydrogen, and Treat Wastewater?

Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Researchers from the University of Colorado Denver College of Engineering and Applied Science have found a way to generate pure hydrogen gas and desalination facilitated by an external power supply.

Organic Solvent System May Improve Recycling of Catalysts

Noble metals such as platinum and palladium are becoming increasingly important because of growth in environmentally friendly applications such as fuel cells and pollution control catalysts. Because the world has limited quantities of these materials, manufacturers will have to rely on efficient recycling processes to help meet the demand.
