Web15 dec. 2024 · The fundamental mechanism of ion selectivity is that ion translocation through atomically thin pores is influenced by electrostatic interactions with charges, chemical affinity with functional groups at pore edges, and steric exclusion of the ion hydration shell in different degrees, etc. Web24 mei 2024 · This manuscript explores the mechanisms of permeation and selectivity in the unusual potassium-selective ion channel TMEM175, which lacks a canonical selectivity filter. The study is led by molecular dynamics simulations and free energy calculations, complemented by a cryoEM analysis and electrophysiological recordings.

WebAbstract Oxygen transport membranes made of Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3− δ (BSCF) were manufactured by tape casting and co-firing. The disk-shaped membranes consisted of a top gastight layer (70 μm thick) and a porous substrate (830 μm thick) with 34% open porosity. The variation of the permeation operation conditions allowed (i) the …
