Virial expansion for charged colloids and electrolytes

, 2002
Using a field-theoretic approach, we derive the first few coefficients of the exact low-density (``virial'') expansion of a binary mixture of positively and negatively charged hard spheres (two-component hard-core plasma, TCPHC).

Morphology, Electrical Performance and Potentiometry of PDIF-CN2 Thin-Film Transistors on HMDS-Treated and Bare Silicon Dioxide

, 2014
In this work, the electrical response of n-type organic field-effect transistors, achieved by evaporating PDIF-CN2 films on both bare and Hexamethyldisilazane (HMDS) treated SiO2 substrates, was investigated by standard electrical characterization and ...

Local non-equilibrium distribution of charge carriers in a phase-coherent conductor

, 1998
We use the scattering matrix approach to derive generalized Bardeen-like formulae for the conductances between the contacts of a phase-coherent multiprobe conductor and a tunneling tip which probes its surface.

Label-Free Potentiometry for Detecting DNA Hybridization Using Peptide Nucleic Acid and DNA Probes

Italian National Conference on Sensors, 2013
Peptide nucleic acid (PNA) has outstanding affinity over DNA for complementary nucleic acid sequences by forming a PNA-DNA heterodimer upon hybridization via Watson-Crick base-pairing.

All-solid-state poly (vinyl chloride) membrane thiocyanate–selective potentiometric electrode

Journal of New Results in Science, 2021
A novel all-solid-state contact poly (vinyl chloride) (PVC) membrane–containing thiocyanate-selective electrode has been prepared. The electrode exhibits the best performance with a membrane composition of PVC:BEHS:ionophore:KTpClPB of 33.0:64.0:2.0:1.0 (

Continuum Theory for Piezoelectricity in Nanotubes and Nanowires

, 2005
We develop and solve a continuum theory for the piezoelectric response of one dimensional nanotubes and nanowires, and apply the theory to study electromechanical effects in BN nanotubes.

Potentiometric Studies on Ion-Transport Selectivity in Charged Gold Nanotubes

Nanomaterials
Under ideal conditions, nanotubes with a fixed negative tube-wall charge will reject anions and transport-only cations. Because many proposed nanofluidic devices are optimized in this ideally cation-permselective state, it is important to know the ...
