Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, Volume 32, Issue 4, Page 1049-1077, July 2026.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Kinetics of Mg-Ni saponite crystallization from precursor mixtures

International audienceSmectite growth is of importance across various fields due to its abundance on the surface of both Earth and Mars. However, the impact of the crystallinity of initial materials on smectite growth processes remains poorly understood.

A Free and Open‐Source Tool for Spectral Unit Mapping Through Clustering of NIR Hyperspectral Images on Mars

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Spectral and hyperspectral data provide essential information on the surface composition of rocky planetary bodies, through which we can reconstruct and understand their origin and geologic evolution. In this field, applications of advanced tools, such as machine learning‐based algorithms, are steadily increasing.

ZnO-Porous Clay Heterostructure from Saponite as Green Catalyst for Citronellal Cyclization

Bulletin of Chemical Reaction Engineering & Catalysis, 2020
Green conversion in organic synthesis is one of the interesting and important topics in green chemistry. The use of heterogeneous catalysis instead of homogeneous catalysis offers some advantages, such as easy separation and reusability. In this research,

The beidellite-saponite series: an experimental approach

European Journal of Mineralogy, 1993
The study of the octahedral Al-Mg series in smectites was conducted using synthesis methods at 200-250°C. All synthesized clays were tetrahedrally charged thus leading to a solid-solution between beidellite and saponite end-members. The TEM chemical microanalyses indicated that the Al-Mg series was continuous between these two end-members without ...
