In coarse-textured soils and gravel pads found in cold regions, hydrocarbon contaminants often migrate into environmentally sensitive areas faster than the rate of in-situ bioremediation. Permeable Reactive Barrier (PRB) technology offers the potential to slow the rate of dispersal and allow remediation over a longer timeframe. Additionally, the reactive media in PRBs can deliver nutrients need...

The present research studies the performance of Converter Sludge (CL)as a nano-activator of persulfate (PS) in Permeable Reactive Barrier (PRB) as an in-situ technology for leachate treatment.In batch experiments, the acidic conditions (pH = 3) have been the most suitable for removal operations, where COD and NH3 removal efficiencies are 69.15% and 60.96%, respectively. The Box–Behnken design (...

Reactive oxygen species (ROS) have emerged as critical players in the pathophysiology of pulmonary disorders and diseases. Earlier, we have demonstrated that ROS stimulate lung endothelial cell (EC) phospholipase D (PLD) that generates phosphatidic acid (PA), a second messenger involved in signal transduction. In the current study, we investigated the role of PLD signaling in the ROS-induced lu...

The inability of most drugs to cross the blood-brain barrier and/or plasma membrane limits their use for biomedical applications in the brain. Cell Permeable Peptides (CPPs) overcome this problem and are effective in vivo, crossing the plasma membrane and the blood-brain barrier. CPPs deliver a wide variety of compounds intracellularly in an active form. In fact, many bioactive cargoes have neu...

soils. A natural obstacle to this practice is the accelerated aging of iron and loss of reactivity resulting from O2 Permeable zerovalent iron (Fe0 ) barriers have become an estabin the soil atmosphere. Despite this apparent limitation, lished technology for remediating contaminated ground water. This same technology may be applicable for treating pesticides amenable situations could arise wher...
