We investigated the effect of microplastics on nitrogen removal in freshwater sediments where microorganisms and benthic invertebrates (i.e., chironomid larvae) co-existed. Using microcosm experiments, sediments with and without invertebrate chironomid larvae were exposed to microplastics (polyethylene) at concentrations of 0, 0.1, and 1 wt%. After 28 days of exposure, the addition of microplastics or chironomid larvae promoted the growth of denitrifying and anammox bacteria, leading to increased total nitrogen removal, in both cases. However, in microcosms with chironomid larvae and microplastics co-existing, nitrogen removal was less than the sum of their individual effects, especially at microplastics concentration of 1 wt%, indicating an adverse effect on microbial nitrogen removal mediated by macroinvertebrates. This study reveals that the increasing concentration of microplastics entangled the nitrogen cycling mediated by benthic invertebrates in freshwater ecosystems. These findings highlight the pursuit of a comprehensive understanding of the impacts of microplastics on the functioning in freshwater ecosystems.}, journal={SCIENCE OF THE TOTAL ENVIRONMENT}, author={Huang, Yuyue and Li, Wei and Gao, Jie and Wang, Fang and Yang, Wei and Han, Le and Lin, Dunmei and Min, Bolin and Zhi, Yue and Grieger, Khara and et al.}, year={2021}, month={Feb} }

In general, the enantioseparation systems in NACE are similar to those of aqueous capillary electrophoresis (CE) except pure organic solvents are used. The influence of important parameters such as concentration and type of chiral selectors, apparent pH, ionic strength, temperature, and control of electroosmotic flow is discussed. In addition, the reported applications of NACE separations of racemates are presented.}, number={1-2}, journal={JOURNAL OF CHROMATOGRAPHY A}, author={Wang, F and Khaledi, MG}, year={2000}, month={Apr}, pages={277–293} }

The charges of the basic enantiomers were controlled by adjusting the buffer pH. At pH 2.5, basic compounds are positively charged and interact stronger with the negatively charged CD than with neutral CDs, owing to the extra electrostatic interaction. This additional interaction is very useful for chiral separations of the enantiomers that interact weakly with the neutral CDs. For example, chiral separations of acebutolol, metanephrine, normetanephrine, nafronyl, labetalol, and nadolol were achieved at this pH. For labetalol and nadolol that have two chiral centers, three of the four isomers were separated. The capillary surface was dynamically coated with poly(vinyl alcohol) (PVA) to reduce the possible interactions between solutes and the capillary wall, to improve efficiency and reduce the electroosmotic flow (EOF) for enhancing resolution. PVA reduced the interactions between the analytes and the chiral selector; nevertheless, peak tailing was observed owing to the electrodispersion for the compounds that interact too strongly with the anionic CD. At pH 11.6, most of the basic test compounds (except those having phenol groups) are neutral and have weaker interactions with the negatively charged CD. The separation efficiency increased dramatically for all analytes at higher pH owing to the absence of electrodispersion. The existence of the neutral PVA polymer in the buffer solution increased the solubility of the neutral hydrophobic amines and reduced the solute–CD complexation. Chiral separations of a large number of compounds were achieved at a single concentration of the charged cyclodextrin. ©1999 John Wiley & Sons, Inc. J Micro Sep 11: 11–21, 1999}, number={1}, journal={JOURNAL OF MICROCOLUMN SEPARATIONS}, author={Wang, F and Khaledi, MG}, year={1999}, pages={11–21} }

Several profens and amino acids could only be separated by QA-β-CD in pure formamide system. No chiral separation of the profens was achieved in the following solvents: N-methylformamide, methanol, dimethyl sulfoxide, and water; however, chiral separations of most of the amino acids were obtained in all of these solvents. The effects of other experimental parameters such as the CD concentration and apparent pH (pH*) were also investigated. The first application of nonaqueous CE chiral separation of ketoprofen in a commercially available sample, Actron, was also examined. In addition, the reversal of electroosmotic flow by QA-β-CD was observed in water, formamide, N-methylformamide, methanol, and dimethyl sulfoxide media.}, number={1-2}, journal={JOURNAL OF CHROMATOGRAPHY A}, author={Wang, F and Khaledi, MG}, year={1998}, month={Aug}, pages={121–128} }
