A review on lithium recovery using electrochemical capturing systems
( Elsevier , 2021 , Article Review)Resource recovery from natural reserves is appealing and Li extraction from different brines is in the forefront. Li extraction by membranes is reviewed in the literature much more than electrochemical processes. However, ... -
Review on PCL, PBS, and PCL/PBS blends containing carbon nanotubes.
( Budapest University of Technology and Economics , 2018 , Article Review)Biodegradable polymers received considerable attention due to their contribution in the reduction of environmental concerns and the realization that global petroleum resources are finite. The development of double crystalline ... -
Review on recent advances in polythiophene based photovoltaic devices
( Elsevier Ltd , 2016 , Article Review)Discovery of conducting polymer introduced us to the total polymeric solar cells (PSC). During the last decade, power conversion efficiency (PCE) of these solar cells has increased from 1% to 11.5% (with the bulk heterojunction ... -
Review on Surfactant Flooding: Phase Behavior, Retention, IFT, and Field Applications
( American Chemical Society , 2017 , Article Review)Surfactant flooding is an important technique used in enhanced oil recovery to reduce the amount of oil in pore space of matrix rock. Surfactants are injected to mobilize residual oil by lowering the interfacial tension ... -
Review on two-terminal and four-terminal crystalline-silicon/perovskite tandem solar cells; progress, challenges, and future perspectives
( Elsevier , 2022 , Article Review)Silicon (Si) solar cells are the dominant and well-developed solar technology holding more than 95% share of the photovoltaic market with efficiencies over 26%. Still, this value is far away from the Shockley–Queisser limit ... -
Revisiting the economic theory of crime A state-level analysis in India
( Cogent OA , 2023 , Article)The economic theory of crime tends to suggest that deterrence variables have a significant impact on crime rates in a society. From an economic perspective, criminals are rational economic agents who weigh the likelihood ... -
Revolutionizing Emergency Healthcare with a Mobile App
