Effect of the vintage year on strontium isotopic ratio (87Sr/86Sr) of wines: a Portuguese case study

Journal of the Science of Food and Agriculture, Volume 106, Issue 3, Page 1940-1947, February 2026.
Abstract BACKGROUND Currently, there is a growing need for wine authenticity tools to face the global wine market and deal with adulteration cases. Stable isotope analyses, recognized by the Organization of Vine and Wine as a tool for detecting authenticity fraud, form the basis of the European Wine Databank, which faces limitations concerning the ...

The Mobility of Major and Trace Elements in EOC Minerals on Parent Chondrite Bodies

Geosciences
The combined EPMA and SIMS study of the geochemical features of olivine, low-Ca pyroxene and plagioclase in equilibrated ordinary chondrites (EOCs) has revealed the effect of thermal metamorphism on trace element concentrations in EOC silicate minerals ...

Coupled Experimental Study and Thermodynamic Modeling of GeO2 and GeO2–CaO and GeO2–SiO2 Binary Systems

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...

Characterizing Martian Primary Crustal Compositions With Gamma Ray Spectroscopy

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Mars's global‐scale chemical maps of the midlatitudes, derived from Mars Odyssey gamma and neutron spectroscopy, have constrained martian geology across a multitude of processes. However, the chemical maps are often used to analyze pre‐defined regions based on mapped geology and/or mineralogy.

Full‐Wave SKS Splitting Intensity Tomography Suggests Depth‐Dependent Upper Mantle Fabrics and Anisotropy Beneath Alaska

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Alaska's tectonic complexity makes it ideal for probing upper mantle deformation. We present a 3D shear‐wave anisotropy model obtained by inverting 7,985 SKS splitting intensity measurements from 261 broadband stations using 941 events from 2000 to 2023.

Comparative Advances in Sulfide and Halide Electrolytes for Commercialization of All‐Solid‐State Lithium Batteries

Advanced Materials, Volume 38, Issue 2, 8 January 2026.
This review compares sulfide‐ and halide‐based solid electrolytes for all‐solid‐state lithium batteries (ASSBs), highlighting their ionic conductivity, chemical stability, manufacturability, and compatibility with lithium metal. Sulfides offer higher conductivity, while halides provide enhanced stability and scalability.
