Advanced Healthcare Materials, EarlyView.This work introduces a microsphere‐templated strategy to fabricate reprocessable PEDOT:PSS syntactic foams with tunable porosity, stable conductivity, and 3D printability. In situ PEDOT:PSS coatings create a conductive network that maintains electrical performance at high void fractions.

Dynamics of active magnetic thrust-bearings.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 A linearlized model considering the effect of eddy currents is shown to be useful for the analysis of the dynamics of active magnetic thrust-bearings, in which electromagnet cores are composed of solid steel. The dynamics of a magnetic control-force is modeled by the first-order time-lag system with unknown parameters : a gain and a time constant.

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Experimental Identification of an Aerostatic Thrust Bearing [PDF]
, 2016 Conventional approaches to design aerostatic bearings are based on their static characteristics. However, dynamic predictions are fundamental in order to obtain very precise positioning since air bearings are frequently subjected to dynamic load variations.
