The most da advantage of this design is that it solves the PEG-Dilemma. Peg-dilemma has three main points: 1. The steric hindrance of PEG chains shields the interaction between liposomes and cell membranes and inhibits the uptake of liposomes by target cells; 2. Shielding the interaction ...
Lithium bistrimethylsilylamide is also called lithium hexamethylsilylamide (LiHMDS). Lithium bistrimethylsilylamide can be used to prepare low-coordination metal complexes because the ligand (TMS) 2N- has a large steric hindrance. Such examples are M[N(TMS)2]3 (M=Sc,Ti,V,Fe; TMS=(CH3)3SCh...
What is the hybridization of the central atom in {eq}NI_3 {/eq}? Nitrogen triiodide: Nitrogen triiodide is a compound of nitrogen and iodine as it is made up of one nitrogen and three iodides. It is an unstable compound as there is steric hindrance due to the small size of nitrogen....
