Metal–organic frameworks (MOFs) are superior sorbents for water adsorption-based applications. The unique step-like isotherm at a MOF-specific relative pressure allows easy loading and regeneration over small range of temperature conditions. With good hydrothermal stability cyclic durability, it stands out classical used in applications humidity control, harvesting, heating cooling. These easil...

Aging earth fill dams that were constructed in the mid-1950’s are beginning to show signs of instability associated with time-dependent degradation shear strength. The strength can be attributed fissures, leaching cementation, and creep highly plastic clays, among other issues. processes being examined an dam experienced slope but did not result a loss water. This paper discusses research findi...

We present the first femtosecond soft x-ray spectroscopy in liquids, enabling the observation of changes in hydrogen bond structures in water via core-hole excitation. The oxygen K-edge of vibrationally excited water is probed with femtosecond soft x-ray pulses, exploiting the relation between different water structures and distinct x-ray spectral features. After excitation of the intramolecula...

Last week we reviewed the history and current use of chlorination in the treatment of drinking water. Our discussion highlighted a number of potential risks associated with chlorine and some of its reaction products. 1 But what are the alternative methods currently under study for disinfecting public water supplies? Which organizations in the US and abroad are concerned with chlorination and wa...
