Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

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.

Passively stabilized magnetic bearings

Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010
This paper presents a new passive magnetic bearing system that is capable to rotate without contact at a short distance from a dedicated stator. The magnetic suspension is assured by the repulsion between two arrangements of permanent magnets located both on toroidal shaped stator and rotor. The stator magnets are surrounded by a conductive sheet.

Sensors For Magnetic Bearings

[1993] Digests of International Magnetics Conference, 1993
A variety of distance sensors suitable for application to magnetic levitation is examined. The characteristics of the sensors regarding the phase shift between in- and outgoing signals, frequency response, DC-stability, stability to EMF interference, resolution and temperature stability are analyzed.
