Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Electrochemical Cobalt‐Catalyzed C−H Activation
Chemistry – A European Journal, 2018 AbstractCarbon–heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C−H activation has emerged as arguably the most efficient strategy to construct C−Het bonds. Despite of major advances, these C−H transformations were largely dominated by precious transition metal catalysts,
