On the Conservatisms of Nepheline Predictors for Canister Centerline Cooled (CCC) High‐Level Waste (HLW) Glasses

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Multiple models and feature sets have been generated, which attempt to predict the crystallization of nepheline (NaAlSiO4) in high‐level radioactive waste (HLW) glasses under canister centerline cooling (CCC) conditions. Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and ...

Impact of V2O5 on the Dissolution Behavior of Sodium Aluminoborosilicate‐Based Model Nuclear Waste Glass

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Understanding how vanadium oxide (V2O5) influences the dissolution behavior of nuclear waste glasses is essential for optimizing their waste loading and long‐term durability. In this work, a series of sodium aluminoborosilicate‐based model glasses—(100−x) (30Na2O–5Al2O3–15B2O3–50SiO2)—xV2O5, where x = 0, 2.5, and 5 mol.%—were synthesized to ...

Methodical Fiber Push‐In Indentation for Improved Statistical Assessment of Interfacial Shear Strength in CMCs

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
Quantitative Microscopy combined with nano‐indentation was used to evaluate fiber–matrix sliding stress in CMCs. This approach enabled application of a push‐in shear‐lag model to a large fiber population, providing robust statistical analysis. ABSTRACT Ceramic matrix composites (CMCs) are advanced materials known for their exceptional thermal stability,

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Influence of Processing Variables on the Hydrothermal Synthesis of Zeolite–Geopolymer Aggregates from Kaolin

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT This study addresses the influence of key processing variables on the hydrothermal alkaline treatment of low‐temperature fired kaolin‐aggregates for the development of zeopolymers (zeolite–geopolymer composites). Parameters such as hydrothermal treatment temperature (90 and 150°C), reactor volume (250 and 500 mL), liquid‐to‐solid (L/S) ratio ...

Connecting Bond Switching to Fracture Toughness of Calcium Aluminosilicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Fracture toughness is a critical mechanical property of glasses, but a detailed understanding of its link to composition and structure is still missing. Here, focusing on the industrially important family of calcium aluminosilicate glasses, we measure the fracture toughness of two glass series using the single‐edge precracked beam method, one ...

The Transcription Factor OsWRKY64 Interacts With OsART1 to Positively Regulate Al Resistance in Rice

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4656-4671, July 2026.
A proposed working model illustrating the cooperative regulation of Al tolerance by OsWRKY64 and OsART1 in rice. Under Al stress conditions in acidic soil, the transcription factor OsART1 directly binds to the promoter of OsWRKY64 to activate its transcription. The synthesized OsWRKY64 protein then physically interacts with OsART1 in the nucleus.

Proton‐Exchanged Montmorillonite With Interlayer Accessibility as a Solid Acid Catalyst for the Upcycling of Polyoxymethylene

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The first microwave‐assistance‐free heterogeneous catalytic upcycling of polyoxymethylene (POM) into valuable cyclic acetals is achieved with a reusable proton‐exchanged montmorillonite (H‐Mont) catalyst. Combining interlayer accessibility with strong acidity, H‐Mont enables efficient, regenerable, and versatile transformations with potentially biomass‐
