Contamination in subsurface environment is a serious environmental hazard. Main sources of the contamination are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines and different industries. Permeable reactive barriers (PRBs), which promising technology to remediate groundwater in-situ, filled with materials for removal contaminants present groundw...

Soil is one of our most important natural resources. Regrettably, the expansion human activities has resulted in degradation soil resource due to contamination with a myriad organic and inorganic compounds. The remediation mixed contaminated soils, i.e. soils both compounds metals, challenging as it requires actions simultaneously decrease metal-induced risks contaminant concentrations. Here, w...

The use of nanomaterials has spread and been applied in different industries, including agriculture. Here, the possibilities presented by NMs are very varied, from biostimulation favorable responses, or control pests diseases, to monitoring characteristics interest with nanosensors. Particularly agricultural crops is relevant, since this process stress tolerance, higher content biocompounds, et...

Despite more than 30 years of experience with low level laser therapy (LLLT) or 'biostimulation' in dentistry, concerns remain as to its effectiveness as a treatment modality. Controlled clinical studies have demonstrated that while LLLT is effective for some specific applications, it is not a panacea. This paper provides an outline of the biological basis of LLLT and summarizes the findings of...

Sources of contamination in a subsurface environment are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines, and different industries. The permeable reactive barrier (PRB) is promising technology to remediate groundwater in-situ. In this study, synthetic samples containing toluene treated three reactor columns by biological processes. PRB-1 consis...
