Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics
Advanced Materials, Volume 37, Issue 13, April 2, 2025.Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Valve Traction Motors in Vehicle Electric Drive
Izvestiya MGTU MAMI, 2008 A valve traction motor (VTM) is a contactless analogue of a DC traction motor (there is a mechanical collector-brush contact). The VTM with permanent magnet excitation has supplementary advantages: reliable exitation and its loss absence, the possibility of working with 1 or less zero coefficient of power.
