Investigating the effect of Pb on As determination in soil materials using x‐ray fluorescence spectrometry at high levels of Pb contamination

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract X‐ray fluorescence spectrometry (XRF) is a method of quantifying elements in soil and other media widely used by researchers in many fields. Inaccuracy in XRF can result from spectral interference between Pb and As, two of the most toxic and highly prevalent soil contaminants.

Non‐Destructive Analysis of Phenolic and Flavonoid Contents in Medicinal Plant Powders Using Hyperspectral Imaging and Variable Selection

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Phenolic and flavonoid contents in medicinal plants are essential to their growth and development and provide numerous health benefits, yet their quantification using traditional wet chemistry is labor‐intensive and time‐consuming. This study utilized the combination of two benchtop hyperspectral imaging (HSI) systems, namely short‐wave ...

Model‐Data Comparison of Electron Energization Associated With Kinetic Alfvén Waves in the Near Earth Magnetotail

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract A model‐data comparison between Gyrofluid‐Kinetic Electron simulations and MMS satellite observations of kinetic Alfvén waves (KAW) and associated electron energization in the near Earth magnetotail is presented. The observations reveal 10 keV electron beams embedded within intense KAW field‐aligned currents.

The Exceptional Challenges of Si‐Based Anodes and the Eternal Hunt for Electrolyte Additives: A Perspective on the Example of a Novel Dioxazaborole‐Based Molecule

Small Science, Volume 6, Issue 11, November 2026.
An ideal electrolyte additive, particularly for Si‐based anodes, should (i) promote the formation of an effective SEI, i.e., passivating and suppressing LiPF6/SiOx‐contact, (ii) minimize active Li loss (ALL) through efficient SEI formation, (iii) ideally enable “SEI‐waste” recovery and/or (iv) undergo sacrificial oxidation for prelithiation purposes ...

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Is Magnetic Reconnection Dominantly Spatially or Temporally Variable: First Results From TRACERS

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites (TRACERS) small explorer mission was designed to: Determine whether magnetopause reconnection is primarily spatially or temporally variable for a range of solar wind conditions. Observations from the Analyzers for Cusp Ions (ACIs) on the two TRACERS spacecrafts are used

High Doses of N‐Acetyl‐P‐Aminophenol Cause Acute Changes in Electroencephalographic and Electrocardiographic Activities in Wistar Rats

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 5, November 2026.
ABSTRACT N‐acetyl‐p‐aminophenol (APAP), or acetaminophen, is the most prescribed analgesic and antipyretic, even used in association with other drugs. Because it is easily bought in drugstores, much evidence about its toxic effects is known due to high doses or continuous use, which can lead to death in cases of intoxication.
