离子主要通过载体或通道机制跨膜运输。在此,据报道,一类独特的分子机器激发的膜转运蛋白称为分子摆动,它利用以前未探索的摆动机制以高效的方式促进离子传递。尤其是,带有15冠-5单元作为离子结合和传输单元的分子摇摆,具有极高的离子迁移活性,EC 50值为46 n m(通道:脂质摩尔比为1:相对于脂质为4800或0.021 mol%),对于K +和Na +离子分别为110 n m。值得注意的是,在富含胆固醇的环境中,这种离子迁移活性仍然很高,达到EC 50对于K +和Na +离子,其值分别为130(相对于脂质/胆固醇为0.045 mol%)和326 n m。

A polyviologen-based adsorbent was prepared via polymerization of a viologen-dialdehyde with a hydroxyl-substituted aryl-dihydrazide in acidified water.
copper selectivesensor 2 based on hydrazide and salicylaldehyde has been designed and prepared. Sensor 2 behaves a single selectivity and sensitivity in the recognition for Cu2+ over other metal ions such as Fe3+, Hg2+, Ag+, Ca2+, Zn2+, Pb2+, Cd2+, Ni2+, Co2+, Cr3+ and Mg2+ in DMSO. The distinct color change and the rapid changement of fluorescence emission provide naked‐eyes detection for Cu2+. The

An example of a multi-fluid kit for three-dimensional printing includes a binder fluid and an adhesion promoter fluid. The binder fluid includes water and polymer particles in an amount ranging from about 1 wt% to about 40 wt% based on the totalweight of the binder fluid. The adhesion promoter fluid includes water and an aromatic dihydrazide adhesion promoter in an amount ranging from about 0.1 wt% to about 10 wt% based on a total weight of the adhesion promoter fluid.

An electron-transporting anion prepared by anchoring a sulfonate group onto an electron-transporting molecule through a flexible alkyl chain and its use as the counter anion in a cationic iridium complex is reported. The flexible alkyl chain improves the solubility of the bulky anion in water or in polar organic solvents. The anion exhibits similar photophysical and electrochemical properties to the
