Alkylimidazolium-based ionic liquids with tailored anions and cations for CO capture.

A systematic investigation was conducted in the present study to determine how various cations and anions affected the solubility of CO. To investigate the influence of different cations and anions on the solubility of CO, twelve ILs were synthesized, characterized, and utilized. These ILs comprised five distinct anions (dioctylsulfosuccinate [DOSS], triflouromethanesulfonate [TFMS], dodecylsulfate [DDS], 3-sulfobezoate [SBA], and benzene sulfonate [BS]), and four distinct cations (1-butyl-3-propanenitrile imidazolium [CCN Bim], 1-hexyl-3-propanenitrile imidazolium [CCN Him], 1-octyl-3-propanenitrile imidazolium [CCN Oim], and 1-decyl-3-propanenitrile imidazolium [CCN Dim]).

Metal complex as p-type dopant-based organic spiro-OMeTAD hole-transporting material for free-Li-TFSI perovskite solar cells.

Lithium bis(fluorosulfonyl)imide (Li-TFSI) is an efficient p-dopant that has been used to enhance the conductivity of perovskite solar cells (PSCs). However, the performance of the corresponding devices is still not satisfactory due to the impact of Li-TFSI on the fill factor and the short-circuit current density of these PSCs. Herein, a new Mn complex [(Mn(Me-tpen)(ClO4)2-)]2+ was introduced as a p-type dopant into spiro-OMeTAD and was successfully applied as a hole transport material (HTM) for PSCs.

Application of capillary electrophoresis with capacitively contactless conductivity detection for biomedical analysis.

The coupling of capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection (C D) has become convenient analytical method for determination of small molecules that do not possess chromogenic or fluorogenic group. The implementations of CE with C D in the determination of inorganic and organic ions and amino acids in biomedical field are demonstrated. Attention on background electrolyte composition, sample treatment procedures, and the utilize of multi-detection systems are described.
