A review on multicomponent rare earth silicate environmental barrier coatings

Journal of Materials Research and Technology
Rare earth (RE) silicate environmental barrier coatings (EBCs), with superior physicochemical properties and resistance to hot water-oxygen and calcium-magnesium-aluminosilicate (CMAS) corrosion, are ideal candidates for safeguarding the next-generation ...

On the evidence for evidence‐based conservation

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
We explore the evidence base underlying evidence‐based conservation (EBC). Drawing on varied examples, we suggest that EBC is often (but not always) a justified investment to improve conservation outcomes. We offer suggestions for how to generate further evidence on EBC, framed around a theory of change for how EBC improves conservation outcomes ...

Rheological and Morphological Characterization of Acrylonitrile Butadiene Styrene (ABS)/Linear Low‐Density Polyethylene (LLDPE) Blends Containing Carbon Nanotubes

ChemistrySelect, Volume 11, Issue 8, 25 February 2026.
ABSTRACT Acrylonitrile butadiene styrene (ABS) is a widely used polymer in the automotive, electronics, and household appliance industries. Despite its extensive use, ABS suffers from low thermal stability, flammability, poor UV stability, and limited recyclability.

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of
