Abstract:
... Hybrid siloxane-phosphocholines (SiPCs) are a unique class of lipids that possess the capacity to spontaneously form unilamellar vesicles (ULVs) that are ∼100 nm in diameter upon exposure to aqueous media without the need for extrusion. These hybrid SiPCs do not negatively impact the growth of a number of bacterial strains and were subsequently explored as candidates for the delivery of a model co ...

Abstract:
... Dibenzoarsacrowns have been synthesized as a novel class of heteroatom-fused crown ethers. The dibenzoarsacrowns can size-selectively capture alkali metal cations, and the arsenic atoms chemoselectively coordinated to gold(i) chloride (AuCl) due to the soft Lewis acid–base interaction. It is notable that the AuCl complex of 21-dibenzoarsacrown-7 further encapsulated Na⁺ with the enhanced associati ...

Currently, removing superficial sulfur is an effective way to solve this issue. Here, we successfully achieved the deep encapsulation of sulfur and removal of superficial sulfur by a simple filtration-washing approach. As expected, the obtained products ex ...
