Optimal Linear Controller for Minimizing DC Voltage Oscillations in MMC-Based Offshore Multiterminal HVDC Grids

The paper aims at minimizing DC voltage oscillations in offshore multiterminal high-voltage direct current (HVDC) grids based on modular multilevel converters (MMCs). The DC voltage stability is a crucial factor in multiterminal HVDC networks since it is a ...

Influence of ion-induced secondary electron emission parameters in PICMC plasma simulations with experimental validation in DC cylindrical diode and magnetron discharges

Ivo Furno, Alban Sublet, Thibaut François Hugo Richard

Niobium thin lms are used at CERN (European Organization for Nuclear Research) for coatings of superconducting radio-frequency (SRF) accelerating cavities. Numerical simulations can help to better understand the physical processes involved in such coatings ...

Unique carbon-nanotube field-effect transistors with asymmetric source and drain contacts

Nicola Marzari, Ho Ling Li

We have fabricated a type of unique single-walled carbon nanotube field-effect transistor, in which the channel length is only 90 nm and aluminum and gold are used as its drain and source electrodes, respectively. The channel conductance oscillations cause ...

Use of Zr/ZrO2 as a counter electrode for the minimization of loss reactions in single compartment electrolysis cells

Christos Comninellis

A preliminary study was made of the cathodic properties (redn. of Ce(IV) and hydrogen evolution) of ZrO2 layer formed on Zr by thermal decompn. at high temp. Zr was chosen as base metal due to the fact that this valve metal is stable under conditions of hy ...
