Influence of Ink Composition and Drying Technique on the Performance and Stability of Fe‐N‐C‐based High‐Temperature Proton Exchange Membrane Fuel Cells

ChemSusChem, Accepted Article.
Fe‐N‐C catalysts have emerged as a potentially cost‐effective alternative to Pt‐based catalysts in high‐temperature polymer electrolyte membrane fuel cell cathodes. However, the optimal design and deposition method of Pt‐free catalyst layer remains unclear.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

Contributions to Plasma Physics, EarlyView.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

β‐Hydroxy β‐Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile

Drug Testing and Analysis, EarlyView.
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

Analytical and Pharmacological Characterization of 1‐(Furan‐2‐Carbonyl)‐LSD (1F‐LSD) and Comparison With 1‐(Thiophene‐2‐Carbonyl)‐LSD (1T‐LSD)

Drug Testing and Analysis, EarlyView.
The novel lysergamide 1‐(furan‐2‐carbonyl)‐LSD (1F‐LSD) was analytically characterized. 1F‐LSD showed LSD‐like activity in vivo similar to 1‐(thiophene‐2‐carbonyl)‐LSD (1T‐LSD) used for comparison. Administration studies in mice and LC–MS analysis revealed that 1F‐LSD served as a prodrug.

Rapid and Simple Dispersive Liquid–Liquid Microextraction (DLLME) Sample Preparation for Propofol Analysis in Hair, Blood, and Urine by Gas Chromatography–Mass Spectrometry

Drug Testing and Analysis, EarlyView.
Development and validation of an extraction method based on dispersive liquid–liquid microextraction for the analysis by GC–MS of propofol in three different biological samples (blood, urine, and hair). The proposed method is very simple and rapid.

Identification of Three Novel Tetrahydrocannabinol Analogs in the European Market

Drug Testing and Analysis, EarlyView.
The major isolated ingredient of “CB9” was identified as [2‐(E)‐propen‐1‐yl]‐Δ8‐tetrahydrocannabinol‐acetate of “tresconol” as [2‐propen‐2‐yl]‐Δ9‐tetrahydrocannabinol and of “CBx” as [2‐propen‐2‐yl]‐Δ8‐tetrahydrocannabinol. These compounds have no available spectroscopic or chromatographic data and have never been identified in Cannabis plants, and ...
