Green Biomaterials: Toward a Multidimensional Classification

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 10, October 2026.
A multidimensional framework is introduced to redefine green biomaterials beyond single descriptors such as bio‐based or biodegradable. By integrating material origin, processing, lifecycle performance, biofunctionality, and application context, the framework resolves inconsistencies in current terminology and provides a foundation for the rational ...

129Xe Nuclear Magnetic Resonance Spectroscopy of Metal–Organic Frameworks

open access: yesAnalysis &Sensing, Volume 6, Issue 4, July 2026.
129Xe NMR spectroscopy is a powerful technique to study porous materials. Properties such as pore sizes, pore connectivity, and dynamic switching processes associated with adsorption can be investigated. With its inertness and highly polarizable electron cloud, Xe allows for sensitive monitoring of small changes in the surface chemistry of materials ...

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

open access: yesJournal 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 ...

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Hydration of Na+, Ni2+, and Sm3+ in the Interlayer of Hectorite: A Quasielastic Neutron Scattering Study

open access: yes, 2017
Quasielastic neutron scattering experiments were performed with Na−hectorite, Ni−hectorite, and Sm−hectorite samples in order to find out whether Sm3+ is present in the clay interlayer as a fully hydrated cation (outer-sphere complex), or, as it follows ...

Delamination and Scrolling of the Phyllosilicate Kenyaite

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 6, 07 April 2026.
Kenyaite was delaminated via cation exchange with meglumine. Nanosheets of 1.6 nm thickness are initially locked in a coplanar arrangement but scroll up upon dilution. Kenyaite, Na[Si10O20(OH)] · 4H2O, is a phyllosilicate structurally related to Ilerite and Magadiite, whose platy, nonintergrown morphology makes it a promising precursor for high‐aspect ...

Hydrolysis and Decomposition of Hectorite in Dilute Salt Solutions

open access: yesClays and Clay Minerals, 1982
AbstractThe hydrolysis and decomposition of M-hectorite (M being Na, Li, Mg, or Ca) in dilute solutions of M-chlorides were studied by recording the changes in electrical conductivity (EC) of the clay suspensions with time, and by chemical analyses of the interclay solutions and resulting solid phases.
