Water Absorption and High Electric Conductivity in betha-PbO2 and Ag5Pb2O6 [PDF]

open access: yesarXiv, 2004
Water absorption in lead peroxide betha-PbO2 and Bystroem-Evers compound Ag2[Ag3Pb2O6] has been investigated by infrared spectrometry and electric conductance measurements. Hydrated Ag5Pb2O6 exhibits, between room temperature and 690 K, electric conductivity, at least, order of magnitude higher than pure silver.

Form invariant Sommerfeld electrical conductivity in generalised d dimensions [PDF]

open access: yesComm. Theo. Phys. Vol-56, (2011) 943, 2011
The Sommerfeld electrical conductivity is calculated in d dimensions following Boltzmann kinetic approach. At T=0, the mathematical form of the electrical conductivity is found to remain invariant in any generalised spatial (d) dimensions.

Research on Nonlinear EPDM for ±525kV HVDC Cable Accessories

open access: yesMATEC Web of Conferences, 2019
High voltage direct current (HVDC) cable accessories are usually the weak link in the cable system for the electric field distribution is often extremely uneven, and it has a range of adverse effects in design and manufacture.

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models

open access: yesAdvanced Engineering Materials, Volume 27, Issue 8, April 2025.
In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.
