All spacecraft systems must be minimized with respect to mass, power, and volume. Here, we focus on current efforts to improve system efficiency and reliability for water separation systems to be used on crewed vehicles. These development efforts combine sub-scale systems testing and multi-physics simulations to evaluate candidate approaches. The best performing options will then be ...

The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the nanometer scale. Using a multiscale imaging protocol, a Devonian shale rock sample with heterogeneities is ...

Water-and-energy supply is a global issue of paramount importance. The demand for safe potable water is quickly exceeding the limits of natural regional water resources. Like oil, water is a finite resource; unlike oil, however, water has no alternatives. Water, energy and their environmentally sound solutions are interrelated; and of all the present-day environmental problems, those related to ...
