One of the central topics in environmental bioremediation research is to identify microorganisms that are capable of degrading the contaminants of interest. Here we report application of combined microautoradiography (MAR) and fluorescence in situ hybridization (FISH). The method has previously been used in a number of systems; however, here we demonstrate its feasibility in studying the degrad...

The paper is a short review on the soil decontamination applying ex-situ techniques. Some sources and pathways of soil contamination are discussed. It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-...

We report on the loading and release of curcumin (a hydrophobic polyphenol with anti-inflammatory and anti-bacterial properties) from polyelectrolyte multilayers composed of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS). We have used the in situ techniques of attenuated total reflectance (ATR) FTIR spectroscopy and quartz crystal microbalance with di...

Contamination of the environment resulting from anthropogenic activities such as mining, smelting and agriculture is of great public and political concern. As such, a greater understanding of the mobility, bioavailability and long-term fate of the materials resulting from these activities is needed in order to make more accurate decisions when devising remediation and legislative strategies. To...

Scientific visualization for exascale computing is very likely to require in situ processing. Traditional simulation checkpointing and post hoc visualization will likely be unsustainable on future systems at current trends due to the growing gap between I/O bandwidth and FLOPS. As a result, the majority of simulation data may be lost if in situ visualization techniques are not deployed. In situ...

A number of automated techniques for point measurement of soil moisture content have been developed to an operational level over the past few decades. While each of those techniques have been individually evaluated by the thermogravimetric (oven drying and weighing) method, typically under laboratory conditions, there have been few studies which have made a direct comparison between the various...
