Metalloporphyrin‐Based Cathode for Rechargeable Magnesium‐Ion Batteries: Copper Leaching and Interphase Formation

open access: yesChemSusChem, EarlyView.
The initial cycling of [5,15‐bis(ethynyl)‐10,20‐diphenylporphinato]copper(II) electrodes in rechargeable Mg‐ion batteries is studied using electrochemical, spectroscopic, microscopic, and spectrometric methods such as total reflection X‐ray fluorescence spectrometry and time‐of‐flight secondary ion mass spectrometry .

Isomer Composition Assessment of Synthetic Phosphatidylethanol by Collision‐Induced and Ozone‐Induced Dissociation Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
This study examines the isomeric composition of PEth reference materials and compares it with the natural variation in isomer distribution found in blood samples. ABSTRACT The direct blood‐alcohol biomarker phosphatidylethanol (PEth), especially its most abundant analogue 1‐palmitoyl‐2‐oleoyl‐sn‐phosphatidylethanol (PEth 16:0/18:1) has gained ...

Analysing Effects of Birth Order on Intelligence, Educational Attainment, Big Five, and Risk Aversion in an Indonesian Sample

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract Few studies have examined birth order effects on personality in countries that are not Western, educated, industrialized, rich, and democratic (WEIRD). However, theories have generally suggested that interculturally universal family dynamics are the mechanism behind birth order effects, and prominent theories such as resource dilution would ...

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

open access: yesDrug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
