TL;DR: In this paper, a Nafion membrane-supported ionic liquid-solid phase microextraction (SPME) coupled with GC-MS technique for the simultaneous sampling and determination of ultra trace polycyclic aromatic hydrocarbons (PAHs) in aqueous samples has been developed.

TL;DR: In this article, six polyvinylimidazolium-based ionic liquids were prepared for use as stationary phases for gas chromatography, and linear solubility parameter experiments were conducted to characterize the specific interactions of these stationary phases.

TL;DR: In this article, the anion effects on the polymers were examined and discussed and the results indicated that anions significantly influence ionic liquid polymers which give them potential to extend the range of options for the stationary phases in gas chromatography.

TL;DR: In this article, a one-pot methodology was successfully developed to synthesize chiral imprinted silica nanospheres with hollow and mesoporous structures, which demonstrated high capacity and chiral selectivity for L or D-3,4-dihydroxyphenylalanine (L- or D -DOPA) and possessed potency for L-DOPA controlled release.

TL;DR: The main purpose of this study is to assess the chemistry competence of freshmen at technology colleges in Taiwan and the results will provide references for preparing remedial materials in chemistry for technology college students.
