In pharmaceutical R & D, drug stereochemistry, and consequently the rotation of enantiomers, is very important. Because they act as chiral selectors in vivo, biomacromolecules have been extensively used as chiral selectors for the liquid chromatographic (

Investigation of retention behavior of imidazoline receptor ligands on mixedmode HILIC stationary phase [PDF]
, 2018 Retention mechanism in the hydrophilic interaction liquid chromatography (HILIC) mode is complex and still a subject of many controversial interpretations. In order to describe the HILIC retention mechanism, different retention models can be employed.

A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery
Advanced Robotics Research, EarlyView.A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Advanced Science, EarlyView.This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

Using Thermodynamics to Evaluate Stationary Phase Polarity in Gas Chromatography- A New Look
, 2022 Gas chromatography is a separation method in which the components of a sample partition between a gaseous mobile phase (carrier gas) and a solid or liquid stationary phase.
