Concentration‐Dependent Lamellar Organization and Structure–Property Relationships in Melt‐Processed EVA/Cloisite 20A Nanocomposites

Journal of Applied Polymer Science, EarlyView.
Cloisite 20A content tunes the structural and mechanical response of melt‐processed ethylene‐vinyl acetate (EVA) nanocomposites. Expanded basal spacings at 5.0 and 7.5 wt% clay are consistent with polymer‐chain intercalation within ordered clay domains.

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...
