Effect of nepheline syenite particle size on diametrical compression strength and reliability of extruded ceramic Raschig rings used in packed towers

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2013
In order to understand the effect of nepheline syenite particle size on physico-chemical properties of ceramic Raschig rings, the fluxing agent was grinded at different milling times. The compositions were prepared by blending the illitic-kaolinitic clay

The Initial Middle Eastern Experience With the Alterra Adaptive Pre‐Stent: Single‐Center Outcomes From Saudi Arabia

open access: yesCJC Pediatric &Congenital Heart Disease, Volume 5, Issue 2, Page 107-114, April 2026.
Abstract Background The Alterra Adaptive Pre‐Stent, used with the Edwards SAPIEN 3 valve, offers a novel transcatheter option for patients with severely dilated right ventricular outflow tracts (RVOTs) previously unsuitable for conventional transcatheter pulmonary valve replacement (TPVR). No prior experience with this system has been reported from the

Novel Bio‐Based Polyurethane Elastomers Customizable for Orthopedic Devices: Toughness, Rapid Degradability, and Safety

open access: yesSusMat, Volume 6, Issue 1, February 2026.
ABSTRACT Given the increasing global demand for sustainable materials and growing concerns over the depletion of petrochemical resources, we report the synthesis of an amorphous bio‐derived polyester diol, and this diol was polymerized with various isocyanates and butanediol, yielding a novel series of bio‐based polyurethane elastomers (BPUEs). Notably,
