Carbon Energy, EarlyView.Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...

Asymmetric‐Coordinated Indium Single Atoms for Highly Selective Photocatalytic CO2 Reduction
Carbon Energy, EarlyView.This work develops an indium single‐atom photocatalyst (In‐NTO) featuring unique Inδ⁺–N3O2 coordination sites for highly selective CO2 photoreduction. The specific atomic interface steers the reaction pathway exclusively toward CO (95.9% selectivity) by lowering the overall energy barrier and converting the critical *CO protonation step from ...

Efficacy, Safety and Tolerability of Volixibat, an IBAT Inhibitor, in Patients With Intrahepatic Cholestasis of Pregnancy. [PDF]
Liver IntABSTRACT Intrahepatic cholestasis of pregnancy (ICP) presents with cholestatic pruritus, elevated sBA and increased risk of adverse perinatal outcomes. Volixibat is a minimally absorbed IBAT inhibitor that interrupts enterohepatic recirculation. We describe four patients with ICP with pruritus and sBA > ULN treated with volixibat (20 or 80 mg BID ...
