Electrokinetic techniques are a staple of microscale applications because of their unique ability to perform a variety of fluidic and electrophoretic processes in simple, compact systems with no moving parts. Isotachophoresis (ITP) is a simple and very robust electrokinetic technique that can achieve million-fold preconcentration and efficient separation and extraction based on ionic mobility. ...

The H NMR relaxometry in combination with water proton spin–spin relaxation time measurements and rheometry have been applied to study the ionic gelation of 1% w/w aqueous low methoxyl pectin solution induced by divalent Ca cations from a calcium chloride solution. The model-free approach to the analysis of H NMR relaxometry data has been used to separate the information on the static (β) and d...

The electrolytic conductivities for C.I. Acid Orange 15 and C.I. Acid Red 97 have been studied. The electrolytic conductivities have been analyzed by Deby HUckel-Onsager theory, The degree of ionization, , Van’t Hoffs factor, i, and thickness of ionic atmosphere, X. were calculated. Each value diminishes with increasing dye concentration. The dye anion transport number, t, mobility’s,  were a...

Biomolecules assemble to conduct: An ion conducting transparent hydrogel with thermo-reversibility, self-healing and injectable properties can be developed spontaneously through a supramolecular self-assembly of phytic acid guanosine monophosphate at room temperature. The efficient ionic mobility in the self-assembled crosslinked G-quadruplex nanofibres resulted its applicability as gel electro...

We are interested in the class of systems for which the satisfaction of code dependencies is a dynamic process rather than one which is determined purely at load-time. Examples include dynamic delegation, mobile code and agent systems. Such systems exhibit properties which are not well-captured by current typing models. We describe a system of ionic object types which capture these effects and ...

Cardiac activation and consequently performance of the heart can be severely affected by certain electrophysiological anomalies such as irregular patterns in the activation of the heart. Since the wavefront propagation occurs through the diffusion of ions (Na, K, etc.) the reduced mobility of ions can be equivalently represented as a reduction of ionic diffusivity causing irregularities in hear...

12 tracted much attention due to unsur13 passed carrier mobility and high thermal 14 conductivity, 4 combined with excellent 15 chemical and thermal stability down to 16 the nanometer scale. The major drawback 17 is the absence of fundamental band gap, 18 which makes semimetallic graphene unsui19 table for conventional digital logic applica20 tions. Sustained efforts to engineer a band 21 gap i...

Little is known about uranium, U(VI), transport in alkaline and saline solutions. However understanding U(VI) mobility in these conditions is critical due to the storage of U(VI) at high pH and ionic strengths (I). To this end we have studied the geochemical processes taking place in a reservoir, and during transport through quartz sand packed columns. The results show that at pH 10.5 and 11.5 ...
