Enhanced ion transport by graphene oxide/cellulose nanofibers assembled membranes for high-performance osmotic energy harvesting

, 2020
As an emerging potential energy source to address the energy crisis, osmotic energy has attracted increasing attention. Fast ion transport is essential for this blue energy and for other membrane-based energy systems to achieve low membrane resistance ...

Active ion transport by mitochondria

Protoplasma, 1967
The ability of isolated mitochondria to accumulate very large amounts of Ca++ by an active transport mechanism was discovered by V a s i n g t o n and M u r p h y in 1961 [1]. The accumulation process was found to be blocked by respiratory inhibitors and by uncouplers of oxidative phosphorylation, and thus was completely dependent on electron transport

2D Laminar Membranes for Selective Water and Ion Transport

Advanced Functional Materials, 2019
Selective water and ion transport are essential in fields related to the environment, resources, energy, and more. Membranes, especially those constituted by 2D materials, are promising to control mass transport within nano‐ and sub‐nanoscales.

A review: applications of ion transport in micro‐nanofluidic systems based on ion concentration polarization

, 2020
Lab‐on‐a‐chip has been used widely in rapid, high‐throughput and low‐consumption analysis of samples in biochemistry. The ion concentration polarization (ICP) produced by ion‐selective transport of nanochannels provides a novel solution for problems in ...

Localized Electrons Enhanced Ion Transport for Ultrafast Electrochemical Energy Storage

Advances in Materials, 2020
The rate‐determining process for electrochemical energy storage is largely determined by ion transport occurring in the electrode materials. Apart from decreasing the distance of ion diffusion, the enhancement of ionic mobility is crucial for ion ...

Transport Energy – Lithium Ion Batteries

2014
This chapter focuses on the technological status and most common chemistries of lithium ion batteries. According to IEA, in the year 2012, the global stock of plug-in hybrid electric vehicles (PEHVs) and electric vehicles (EVs) amounted to more than 18 0000, representing only 0.02 % of all vehicles.

Ion Transport in Excitable Cells

Protoplasma, 1967
All the available evidence indicates that there are two different and entirely distinct pathways by which sodium and (potassium ions can cross the membranes of nerve and muscle fibres—the excitability mechanism and the pump (or recovery) mechanism. The two types of channel for the passage of cations exist side by side in the membrane, but as can be ...

Transport of Ions

1977
We can begin the discussion of ion equilibria by considering a particularly simple practical instance. Let there be two solutions, say 10 mM and 100 mM potassium chloride, separated by a cation-permeable membrane. The membrane may be made, e.g., of a cation-exchange resin and contain pores lined with fixed negative charges.
