The band gaps of seven stacking patterns of bilayer hexagonal boron nitrides(h-BNs) are regulated by changing the doping positions of carbon atoms using density functional theory calculations.The calculation results dwell on that the AA1 stacking pattern h-BN Outdoor has the largest band gap among seven stacking patterns of h-BNs.The influences of
Regional lymph node metastasis (LNM) increases the risk of distant metastasis in papillary thyroid cancer (PTC) patients.However, it remains unclear how tumor cells in PTC patients Slippers with LNM evade immune system surveillance and proceed to colonize distant organs.Here, we comprehensively characterize the tumor-infiltrating immune cell landsc
Stainless steels (SS) are one of the Arch most widely used, affordable materials in public areas, but suffer from a lack of antibacterial property.Unfortunately, traditional steel casting alloying strategy has limits to add Ag due to the extremely low solubility of Ag in SS.The present work demonstrates a novel powder metallurgy technology to fabri
