MOF-Derived Hollow C, N-Doped CoO Dodecahedral Nanostructure Enwrapped with MgInS Nanosheets for Enhanced Photocatalytic N Reduction.

Design of hierarchical hollow nanoheterostructure materials through interfacial and defect engineering is an innovative approach for achieving optimal charge separation dynamics and photon harvesting efficiency. Herein, we have described a facile technique to fabricate hollow MOF-derived C, N-doped-CoO (C, N-CoO) dodecahedral particles enwrapped with MgInS nanosheets for enhanced N reduction performance. ZIF-67 was initially used as a sacrificial template to prepare hollow C, N-CoO using a carbonization route followed by low-temperature calcination treatment.

Hierarchical UiO-66(-NH)/CuInS S-Scheme Photocatalyst with Controlled Topology for Enhanced Photocatalytic N Fixation and HO Production.

The fabrication of defect rich S-scheme binary heterojunction system with enhanced space charge separation and mobilization is a pioneering approach for improving photoreduction efficiency towards the production of value added chemicals. Herein, we have rationally fabricated an atomic sulfur defect-rich hierarchical UiO-66(-NH)/CuInS n-p heterojunction system by uniform dispersion of UiO-66(-NH) (UN66) nanoparticles over the surface of hierarchical CuInS nanosheets under mild conditions. The designed heterostructures are characterized by using different structural, microscopic, and spectroscopic techniques.

Takayasu's Arteritis in Pregnancy: Challenges During the Ongoing Coronavirus Disease 2019 Pandemic for Optimal Maternal and Neonatal Outcomes.

Takayasu's arteritis is a rare systemic vasculitis affecting the aorta and its primary branches. In developing countries, it is often associated with late diagnosis and high morbidity and mortality. We report a case of Takayasu's arteritis diagnosed in the postpartum period and discuss the challenges faced for optimal outcomes during the ongoing coronavirus disease 2019 pandemic.
