The effects of zinc substitution on the electrical properties of MgNb2O6 thin films

open access: yesJournal of Asian Ceramic Societies, 2021
The effects of zinc substitution on the electrical properties of sol-gel derived MgNb2O6 (Mg1-xZnxNb2O6; MZxNO) thin films were investigated. Accordingly, the experimental results revealed that the optimal optical and electrical properties of the devices

Electrophysiological Consequences of Cardiac Fibrosis

open access: yesCells, 2021
For both the atria and ventricles, fibrosis is generally recognized as one of the key determinants of conduction disturbances. By definition, fibrosis refers to an increased amount of fibrous tissue. However, fibrosis is not a singular entity.

An Uncertainty Modeling Framework for Intracardiac Electrogram Analysis

open access: yesBioengineering, 2020
Intracardiac electrograms (EGMs) are electrical signals measured within the chambers of the heart, which can be used to locate abnormal cardiac tissue and guide catheter ablations to treat cardiac arrhythmias.

Luttinger-liquid-like transport in long InSb nanowires

open access: yes, 1999
Long nanowires of degenerate semiconductor InSb in asbestos matrix (wire diameter is around 50 \AA, length 0.1 - 1 mm) were prepared. Electrical conduction of these nanowires is studied over a temperature range 1.5 - 350 K.

Solid state physicochemical properties and applications of organic and metallo-organic fullerene derivatives [PDF]

open access: yes, 2016
We review the fundamental properties and main applications of organic derivatives and complexes of fullerenes in the solid-state form. We address in particular the structural properties, in terms of crystal structure, polymorphism, orientational ...

Electrical conduction in nanogranular cluster-assembled metallic films

open access: yesAdvances in Physics: X, 2021
A film fabricated by the assembling of nanoparticles that retain, at least partially, their individuality is expected to show substantially different structural and functional properties compared to the case where atoms or molecules are used as building ...

Structure and electrical properties of single-phase cobalt manganese oxide spinels Mn3xCoxO4 sintered classically and by spark plasma sintering(SPS) [PDF]

open access: yes, 2009
Cobalt manganese oxide spinels Mn3 xCoxO4 (with 0.98pxp3) were prepared by the thermal decomposition in air of oxalate precursors. The influence of the thermal treatments on the structure of these materials is emphasized.

Violation of Wiedemann-Franz law at the Kondo breakdown quantum critical point

open access: yes, 2008
We study both the electrical and thermal transport near the heavy-fermion quantum critical point (QCP), identified with the breakdown of the Kondo effect as an orbital selective Mott transition.
