contaminants on the hydraulic conductivity of sand. Bulk sand samples from the Missouri River Valley aquifer— a major source of groundwater supply in the U.S. Midwest— were collected for this study. Sand samples, representing the aquifer and vadose zone...

This study investigates the biogeochemical and inorganic geochemical indicators for past environments and paleohydrology of a high resolution sediment record from the Al-Azraq Basin, Jordan. The second largest basin in ...

The bacterial cell wall is made up of peptidoglycan (PG) and its synthesis is of interest as a target for several antibiotics and for new inhibitor development. Peptidoglycan biosynthesis is a complex process which ...

Zeolitic imidazolate frameworks (ZIFs) are a rapidly emerging class of versatile porous material with many potential applications. Here, we report the construction of an amorphous ZIF (a-ZIF) model from a near-perfect ...

Pulsed ultraviolet light from a XeF excimer laser was used to grow thin films of zinc oxide and tin dioxide on (111) p-type silicon wafers within a versatile high vacuum laser deposition system. This pulsed laser deposition ...

Multidrug resistance (MDR), a clinical outcome characterized by subtherapeutic intracellular drug concentration, is one of the predominant factors limiting effective cancer chemotherapy. Several possible mechanisms and ...

There are twenty standard amino acids which are proteinogenic and can exist in two stereoisomeric forms, D- and L-enantiomers, except for glycine, which is achiral. The D-amino acids are not incorporated in proteins; ...

Controlling the interactions between incident electromagnetic energy and matter is of critical importance for many civil and military applications, such as photocatalysis, solar cells, optics, radar detection, communications, ...
