Facile Synthesis of Pentafluoroorthotelluric Acid
Israel Journal of Chemistry, Volume 66, Issue 5, September 2026.Access to teflate chemistry has been limited by the cumbersome established syntheses of HOTeF5. Here, we present a simple synthetic route to this compound and several OTeF5 transfer reagents from readily available starting materials, enabling their preparation in any standard laboratory.

MedComm – Biomaterials and Applications, Volume 5, Issue 3, September 2026.The current systematic review revealed that stromal cell‐derived factor‐1α (SDF‐1α)‐gene‐activated scaffolds have a beneficial impact on promoting SDF‐1α gene expression and protein production. However, this effect is not observed for vascular endothelial growth factor (VEGF) gene expression and protein quantity and endothelial formation, which may be ...
