Enantioselective Determination of Upadacitinib in Pharmaceutical Formulations Using Reversed‐Phase Chiral Liquid Chromatography [PDF]

J Sep Sci
A reversed‐phase chiral HPLC method was developed for the enantioselective separation and quantification of upadacitinib using a Box‐Behnken design. The validated method was successfully applied to the quantification of upadacitinib in a commercial tablet formulation, and its environmental impact and practicality were evaluated using various assessment

Gas chromatographic enantiomer separation on long-chain alkylated beta-cyclodextrin chiral stationary phases

, 2000
Two new chiral stationary phases, heptakis(2,6-di-O-nonyl-3-O-trifluoroacetyl)-beta-cyclodextrin (DNTBCD) and heptakis(2,6-di-O-dodecyl-3-O-trifluoroacetyl)-beta-cyclodextrin (DDTBCD), were synthesized.

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

Laser &Photonics Reviews, Volume 20, Issue 18, 18 September 2026.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Beyond Batch Addition: Alternative Chemical Fueling Approaches for Enhanced Control of Dissipative Self‐Assembly

ChemSystemsChem, Volume 8, Issue 5, September 2026.
Artificial dissipative systems typically operate under batchwise fuel additions into closed reactors, leading to only transient nonequilibrium states. Alternative fueling approaches show how moving toward thermodynamically open conditions, sustained fuel supply, and reaction‐diffusion control provide enhanced regulation of self‐assembly and access to ...
