Evaluation and Application of Stationary Phase Selectivity for Drug Analysis

Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...

The Analysis of Recreational Drugs in Biological Specimens Using Liquid Chromatography Mass Spectrometry

, 2008
In the last few years, the prevalence of legal party pills in New Zealand has risen dramatically. These pills contain new piperazine designer drugs, two of the more common being 1-benzylpiperazine (BZP) and m-trifluoromethylphenylpiperazine (TFMPP). This

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

Advanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Self‐Seeded Nucleation of PET in a Benign Solvent Yields a High Modulus Aerogel With Ultra‐Low Thermal Conductivity

Advanced Materials, EarlyView.
A new benign solvent (1,3‐diphenylacetone) enables a simple, safe, and sustainable dissolution and gelation method to convert waste PET into low density, monolithic aerogels with high mechanical strength (E = 20 MPa) and remarkably low thermal conductivity (k = 21.9 to 28.9 mW/m·K).

Suppressing Surface Degradation in Na‐Rich Prussian Blue Cathodes via Liquid‐Phase Dehydration

Advanced Materials, EarlyView.
Gas bubbling in a liquid medium lowers the local water vapor pressure and continuously removes desorbed water, enabling effective dehydration of Prussian Blue without inducing surface oxidation. This interfacial mass transfer‐driven process stabilizes the surface chemistry and improves electrochemical performance, providing a strategy for handling ...
