Review on the production of medium and small chain fatty acids through waste valorization and CO2 fixation
(
Elsevier Ltd
, 2020 , Article)
The developing approaches in the recovery of resources from biowastes for the production of renewable value-added products and fuels, using microbial cultures as bio-catalyst have now became promising aspect. In the path ...
Integrating electrochemical and bioelectrochemical systems for energetically sustainable treatment of produced water
(
Elsevier Ltd
, 2021 , Article)
Pollutants present in produced water (PW) are recalcitrant in nature and difficult to treat with simple processes. Energetically sustainable and novel approach was developed by integrating electrochemical cell (EC, Primary ...
Sewage enhanced bioelectrochemical degradation of petroleum hydrocarbons in soil environment through bioelectro-stimulation
(
Elsevier Ltd
, 2020 , Article)
The impact of readily biodegradable substrates (sewage and acetate) in bioelectroremediation of hydrocarbons (PW) was evaluated in a bench-scale soil-based hybrid bioelectrochemical system. Addition of bioelectro-stimulants ...
3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments
(
Elsevier
, 2020 , Article)
Production of methane from hydrate-bearing sediments requires hydrate dissociation for releasing
mobile methane gas in sediments prior to gas production operations. Fines may migrate through or
clog the pore space of ...
Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
(
American Society of Civil Engineers (ASCE)
, 2020 , Article)
The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ...
New model for estimating geometric tortuosity of variably saturated porous media using 3D synchrotron microcomputed tomography imaging
(
John Wiley and Sons Inc
, 2021 , Article)
Tortuosity has a significantimpact on flow and transport characteristics of porous media and plays a major role in many applications such as enhanced oil recovery, contaminant transport in aquifers, and fuel cells. Most ...
Enhancement of Naphthalene Degradation by a Sequential Sulfate Injection Scenario in a (Semi)-Arid Coastal Soil: a Flow-Through Reactor Experiment
(
Springer
, 2020 , Article)
Engineered sulfate injection has been introduced as an effective technology to enhance the remediation of soil and groundwater contaminated by petroleum hydrocarbons. While some studies indicate that sulfate injection is ...
Effects of soaking process on CH4-CO2 replacement efficiency for hydrate-bearing sediments
(
Elsevier
, 2021 , Article)
CH4-CO2 replacement method has the advantages of sequestering carbon dioxide and sediment stability compared to other methods such as depressurization and thermal stimulation. However, the production efficiency using CH4-CO2 ...
Effects of dissolved organic phase composition and salinity on the engineered sulfate application in a flow-through system
(
Springer
, 2020 , Article)
Engineered sulfate application has been proposed as an effective remedy to enhance the rate-limited biodegradation of petroleum-hydrocarbon-contaminated subsurface environments, but the effects of dissolved organic phase ...
Release of colloids in saturated porous media under transient hydro-chemical conditions: A pore-scale study
(
Elsevier
, 2021 , Article)
The deposition and consequent release of colloids pose a significant challenge to the environment, groundwater quality and human health. Subsurface soil contains numerous types of colloids that exhibit a diverse range of ...
