Numerical optimization of ion transport in electrospray mass spectrometry
Electrospray ionization (ESI) has developed into a key component of investigative analyses of samples in numerous biological, chemical, and geological contexts due to its unique ability to preserve the structure of ionized species without fragmentation. It is thus important that we fully understand …

The influence of temperature on ion transport in nanofiltration membranes
Nanofiltration (NF) is a pressure-driven membrane-based solution treatment technology, similar to reverse osmosis (RO). The niche set of applications for NF includes those requiring selectivity between monovalent ions and multivalent ions. Incoming streams to be treated can occur over a wide range …

Beam-Ion Transport in Tokamaks: Thermalization in Large Orbit-Width Regime
… shows that the small orbit-width approximation introduces $\ge$5% errors in the density, parallel momentum, and energy moments when $\rho\sb{\theta}/L = 0.86$ in low-$Z\sb{\rm eff}$ plasmas. These results are observed for all source pitch-angles studied except the deeply passing sources, …

Systems-level design of ion transport membrane oxy-combustion power plants
Oxy-fuel combustion, particularly using an integrated oxygen ion transport membrane (ITM), is a thermodynamically attractive concept that seeks to mitigate the penalties associated with CO 2 capture from power plants. Oxygen separation in an ITM system consists of many distinct physical processes, …

Ion transport in the ileum of the desert locust Schistocerca gregaria, forskal
… gregaria. ScgITP stimulates ileal reabsorption of Cl⁻, K⁺, Na⁺ and fluid and inhibits acid secretion. Stimulation with scgITP causes an increase in both Cl⁻ dependent short-circuit current and transepithelial voltage (Vt) and a decrease in transepithelial resistance (Rt; Irvine et al 1988). …

Influence of external environment on fluid/ion transport in confined nanoscale systems
… significant leap in understanding the nuances of transport phenomenon in nanopore architecture. The large nanopore surface compared to the volume favors a predominant transport of ions. The environment results in a near ideal ion-selective nanoporous membrane. The selective nature of ions can be …

Experimental investigations of oxygen-separating ion transport membranes for clean fuel synthesis
Ion transport membranes (ITMs) are dense ceramic membranes which have the potential for 100% selective separation of oxygen from air. ITMs operate at extreme temperatures (>800°C), necessary for the mobility of lattice oxygen ions: this can result in significant experimental challenges. …

Monte Carlo simulation of ion transport of high strain ionomeric polymer transducers
Ionomeric polymer transducers exhibit electromechanical coupling capabilities. The transport of charge due to electric stimulus is the primary mechanism of actuation for a class of polymeric active materials known as ionomeric polymer transducers (IPTs). The research presented in this dissertation …
