Experimental and Theoretical Study of the Thermal Shock Behavior of Insulating Refractory Materials

Ceramics
This study investigates the thermal shock behavior of three Al2O3-SiO2 commercial insulating refractory materials (JM23, JM26, and JM28) used in high-temperature industries (>1000 °C). Thermal shock resistance was evaluated through experimental tests and

The Arico Ignimbrite—an iconic building stone from Tenerife

Geology Today, Volume 42, Issue 6, Page 305-314, November/December 2026.
Volcanic rocks are important building stones, playing a major role in architectural history, particularly in regions with volcanic activity. Among volcanic rocks, ignimbrites, the products of explosive eruptions, have been used extensively due to their widespread availability, workability and aesthetic qualities. The Arico ignimbrite on Tenerife in the

Rhizobial Symbiosis Enhances Salinity Tolerance in Legumes Through Coordinated Physiological and Molecular Responses: Evidence From Common Vetch and Pea

Plant, Cell &Environment, Volume 49, Issue 11, Page 8912-8931, November 2026.
ABSTRACT Soil salinisation severely constrains crop production. Legumes rely on rhizobial symbiosis for sustainable nitrogen acquisition. Although salinity is known to impair nodulation and nitrogen fixation, how symbiosis influences plant tolerance to salt stress remains unclear.
