Marker Compounds for the Determination of Retention Factors in EKC
Journal of Separation Science, 2010AbstractEKC and its sub‐techniques, such as MEKC and microemulsion EKC, have attracted wide interest in recent years. Investigations on this topic have covered several analytical applications, but attention has also been paid more and more to basic studies.

Recent advances in the development and application of microemulsion EKC
ELECTROPHORESIS, 2007AbstractMicroemulsion EKC (MEEKC) is an electrodriven separation technique. Separations are typically achieved using oil‐in‐water microemulsions, which are composed of nanometre‐sized oil droplets suspended in an aqueous buffer. The droplets are stabilised by a surfactant and a cosurfactant.

Sample stacking for the analysis of catechins by microemulsion EKC
ELECTROPHORESIS, 2007AbstractIn this study, an on‐line concentration method, ASEI (anion‐selective exhaustive injection)‐sweeping technology which was coupled with microemulsion EKC (MEEKC), was used to analyze and detect six catechins ((−)‐epicatechin, (+)‐catechin, (−)‐epigallocatechin gallate, (−)‐epicatechin gallate, (−)‐epigallocatechin, and (−)‐gallocatechin).

Recent Developments in Capillary EKC Based on Carbon Nanoparticles
Electrophoresis, 2009AbstractThis paper provides an overview of the use of carbon nanoparticles (CNPs) as pseudo‐stationary phases (PSPs) in EKC. Specifically, it describes the characteristics and properties of the major types of CNPs used as PSPs in EKC separations, namely C60 fullerenes, carbon nanotubes and covalently modified carbon nanotubes. Based on such properties,

A Test for Parameter Homogeneity in CO2Panel EKC Estimations
Environmental & Resource Economics, 2005This paper casts doubt on empirical results based on panel estimations of an “inverted-U” relationship between per capita GDP and pollution. Using a new dataset for OECD countries on carbon dioxide emissions for the period 1960–1997, we find that the crucial assumption of homogeneity across countries is problematic.

Virtual Water and an EKC for Water Pollution
Water Resources Management, 2016This paper includes country level virtual water data in an Environmental Kuznets Curve (EKC) for water pollution. Virtual water accounts for the total amount of water required to produce a good in all stages of production. This paper constructs a water independence index, defined as the water required in domestic production divided by the amount of ...

This chapter provides a methodological perspective and econometric estimates of delinking, for waste indicators in Europe. EKC are addressed as a natural extension of delinking analysis. They confirm the hypothesis that even European countries, characterized by high income levels and a relatively long waste policy history, are at best experiencing only
