The transport of hydrated ions across nanochannels is central to biological systems and membrane-based applications, yet little known about their structure during due the absence in situ characterization techniques. Herein, we report experimentally resolved ion dehydration transmembrane using modified liquid ToF-SIMS combination with MD simulations for a mechanistic reasoning. Notably, complete was not necessary occur membranes sub-nanometer pores. Partial shedding water molecules from...
State-of-the-art ion-selective membranes with ultrahigh precision are of significance for water desalination and energy conservation, but their development is limited by the lack understanding mechanisms ion transport at subnanometer scale. Herein, we investigate three typical anions (F − , Cl Br ) under confinement using in situ liquid time-of-flight secondary mass spectrometry combination transition-state theory. The operando analysis reveals that dehydration related ion-pore interactions...
Dehydration is a basic phenomenon in ion transport through confined nanochannels, but how it affects trans-membrane selectivity has not been understood due to lack of characterization techniques and suitable pore structures. Herein, hydration number distributions typical alkali metal ions were characterized by combining uniform subnanochannels ZIF-8-based membranes with the situ liquid time-of-flight secondary mass spectrometry (ToF-SIMS) technique, revealing that steric hindrance induced...
Pulsatile ion transport facilitates the adjusted transfer of substances, meeting requirements for gradient and timed separation multiple components in membrane processes. Responsive nanofiltration membranes are thus currently receiving widespread attention but face limitations due to their narrow performance adjustment range. Herein, hydroxyl functional groups were introduced into electrically responsive broaden range through a combination pore size sieving group interactions, resulting...
The effect of aqueous solution chemistry on the ionic hydration structure and its corresponding nanofiltration (NF) selectivity is a research gap concerning ion-selective transport. In this study, distribution two typical monovalent anions (Cl– NO3–) under different chemical conditions transmembrane during NF were investigated by using in situ liquid time-of-flight secondary ion mass spectrometry combination with molecular dynamics simulations. We demonstrate inextricable link between pore...
Multi-stage synchronous induction coil launcher (MSSICL) uses multi-stage drive coils to accelerate projectile. It can launch projectile of great mass. Because every has an optimal trigger time, the accurate control time ensure large muzzle velocity. With increase projectile's velocity, acceleration between different stages in decreases, making more difficult. In this paper, a method software is proposed. Simulation result shows that allow for greater accuracy and response speed, effectively...
Low-maintenance membrane cleaning is essential for the stable operation of bioreactors. This work proposes an in-situ electrical-cleaning method with electro-MBR. When applied bias was increased ephemerally, flux recovered rapidly because scouring effect from gas evolution reactions. The exfoliation cake layer played a major role in mitigating fouling, recovering transmembrane pressure (TMP) by 88.6% under optimal conditions. Membrane modules were not replaced electrical during operation,...
