The crown ethers were strategically integrated at the ... Analytical techniques used to characterize the samples included time-of-flight secondary ion mass spectrometry (ToF-SIMS), ultraviolet ...

Long phenylethynyl ligands were modified to bear macrocyclic polyether rings — 34- and 36-membered crown ethers that have been extensively used as receptors for electron-deficient molecules.

The researchers tested many crown ethers in this study to improve the ... photoelectric conversion efficiency to over 30% when used alongside existing silicon solar cells, thereby increasing ...

Nature ion channels play significant role in the living organisms, which can translocate physiological relevant ions across ...
