A highly efficient fast charger for high capacity batteries and methods for fast charging high capacity batteries. The fast charger preferably comprises a rectified AC input of single or preferably three phases, with an optional power factor corrected input, minimally filtered with high frequency, high ripple current capacitors, which is switched with a power switching circuit in the “buck” configuration into an inductor / capacitor output filter. Metallized film capacitors are employed, to minimize the rectified 360 Hertz AC component filtering while providing transient switch protection and ripple current requirements for the buck regulator, to provide a high current fast charger with substantially improved power factor. High power, high frequency switching with minimized output filter size provides a highly filtered DC output. The fast charger is adapted to be constructed in a modular design for simple maintenance.

Differentiated service classes on a label switch path are managed by comparing at least one packet field value included in a packet of data to mapping field values of a mapping that correlates the mapping field values with queues. The packet is stored into one of the queues based on the comparing. A first subset of the queues is scheduled using a first queue scheduling algorithm and a second subset of the queues is scheduled using a second queue scheduling algorithm. The packet is transmitted onto the label switch path in accordance with a predefined scheduling order of the first subset of the queues and the second subset of the queues.

Highly monodisperse nanocrystals (including CdSe, ZnSe, PbSe, Cu2-xSe, MnSe, Zn1-xCdxSe, CuInSe2, CuInSnSe2, CdTe, ZnTe, PbTe, etc) have been synthesized by using different “green” starting materials to prepare chalcogenide (Se and Te) precursors successfully. Air-sensitive compounds (alkylphosphine, such as trioctylphosphine (TOP) and tributylphosphine (TBP)) have been eliminated to use in the entire synthetic process. As surface coating agents, amphiphilic oligomer (polymaleic acid aliphatic alcohol ester) with different alkyl chain length has been utilized to form oligomer-coated water-soluble nanocrystals.
