Integration of a sensor system into microfluidic chips [PDF]

open access: yes, 2010
There have been considerable developments in the field of potentiometric sensors in recent years mainly with respect to lowering detection limits and making sensors smaller, solid-state, robust and less expensive.[1, 2] In potentiometric measurements two

Approaching Electroencephalographic Pathological Spikes in Terms of Solitons

open access: yesSignals
A delicate balance between dissipative and nonlinear forces allows traveling waves termed solitons to preserve their shape and energy for long distances without steepening and flattening out.

Superconducting crossed correlations in ferromagnets: implications for thermodynamics and quantum transport

open access: yes, 2001
It is demonstrated that non local Cooper pairs can propagate in ferromagnetic electrodes having an opposite spin orientation. In the presence of such crossed correlations, the superconducting gap is found to depend explicitly on the relative orientation ...

Depolarization field in thin ferroelectric films with account of semiconductor electrodes [PDF]

open access: yesarXiv, 2004
Within the framework of the phenomenological Ginzburg-Landau theory influence of semiconductor electrodes on the properties of thin ferroelectric films is considered. The contribution of the semiconductor electrodes with different Debye screening length of carriers is included in functional of free energy.

Thermoelectric energy recovery at ionic-liquid/electrode interface [PDF]

open access: yesarXiv, 2015
A Thermally Chargeable Capacitor containing a binary solution of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)-imide (EMIMTFSI) in acetonitrile is electrically charged by applying a tempera- ture gradient to two ideally polarisable electrodes.

Electrochemical performance of decorated reduced graphene oxide by MoO3 nanoparticles as a counter electrode [PDF]

open access: yesarXiv, 2019
We present an efficient electrocatalytic material based on anchored MoO3 nanoparticles on reduced graphene oxide (RGO) nanosheets. After preparation of graphene oxide (GO), the MoO3 nanoparticles anchored on GO nanosheet by using the arc-discharge method.
