A Vacuum Vapor Deposition Strategy to Fe Single‐Atom Catalysts with Densely Active Sites for High‐Performance Zn–Air Battery

Abstract Iron single?atom catalysts (SACs) have garnered increasing attention as highly efficient catalysts for the oxygen reduction reaction (ORR), yet their performance in practical devices Tank remains suboptimal due to the low density of accessible active sites.Anchoring iron single atoms on 2D support is a promising way to increase the accessi

Significant Depletion of CD4+ T Cells Occurs in the Oral Mucosa during Simian Immunodeficiency Virus Infection with the Infected CD4+ T Cell Reservoir Continuing to Persist in the Oral Mucosa during Antiretroviral Therapy

Human and simian immunodeficiency virus (HIV and SIV) infections are characterized by manifestation of numerous opportunistic infections and inflammatory conditions in the oral mucosa.The loss of CD4+ T cells that play a critical role in maintaining mucosal immunity likely contributes to this process.Here we show that CD4+ T cells constitute Crop T
