Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques

ELECTROPHORESIS, Volume 44, Issue 1-2, Page 158-189, January 2023., 2023
Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...

Capillary supercritical fluid chromatography [PDF]

Analytical Chemistry, 1981
Publisher Summary This chapter discusses the capillary supercritical fluid chromatography (SFC). SFC, a separation method undergoing considerable renaissance lately, has its origins in a pioneering experimental study on metal porphyrins. Increased column performance and speed of analysis in SFC originate in the mobile-phase properties.

Enantioselective CE–MS analysis of ketamine metabolites in urine

ELECTROPHORESIS, Volume 44, Issue 1-2, Page 125-134, January 2023., 2023
Abstract The chiral drug ketamine has long‐lasting antidepressant effects with a fast onset and is also suitable to treat patients with therapy‐resistant depression. The metabolite hydroxynorketamine (HNK) plays an important role in the antidepressant mechanism of action.

Super/subcritical fluid chromatography with packed columns: state of the art and applications

Química Nova, 2014
Separations using supercritical fluid chromatography (SFC) with packed columns have been re-discovered and explored in recent years. SFC enables fast and efficient separations and, in some cases, gives better results than high performance liquid ...

The way to ultrafast, high-throughput enantioseparations of bioactive compounds in liquid and supercritical fluid chromatography [PDF]

, 2018
Until less than 10 years ago, chiral separations were carried out with columns packed with 5 or 3 μm fully porous particles (FPPs). Times to resolve enantiomeric mixtures were easily larger than 30 min, or so.

Organic Electrolytes Recycling From Spent Lithium‐Ion Batteries

Global Challenges, Volume 6, Issue 12, December 2022., 2022
Aged electrolytes inside spent lithium‐ion batteries consist of volatile organic solvents and toxic lithium salts, which can cause severe environmental pollution and safety issues without proper treatment. This review summarizes the reported methods to recycle aged electrolytes as well as achieve progress during industrial recycling technology and ...

Subcritical and supercritical bifurcations in axisymmetric viscoelastic pipe flows [PDF]

J. Fluid Mech. (2021), vol. 929, A16, 2021
Axisymmetric viscoelastic pipe flow of Oldroyd-B fluids has been recently found to be linearly unstable by Garg et al. Phys. Rev. Lett., 121.024502 (2018). From a nonlinear point of view, this means that the flow can transition to turbulence supercritically, in contrast to the subcritical Newtonian pipe flows.
