Three-phase Half-controlled Boost Converter Operating in Quasi-critical Conduction Mode
(Ieee, 2018-01-01)
AC-DC converters, which operate in discontinuous conduction mode, can be used as power factor correction. Operating with constant duty cycle, the control system presents low complexity, however, for low static voltage ...
Conducting polymer formed by low energy gold ion implantation
(AMER INST PHYSICS, 2008)
A buried conducting layer of metal/polymer nanocomposite was formed by very low energy gold ion implantation into polymethylmethacrylate. The conducting layer is similar to 3 nm deep and of width similar to 1 nm. In situ ...
Stagnant effective thermal conductivity of agro-industrial residues for solid-state fermentation
(2013-10-03)
The stagnant effective thermal conductivities (K0) of sugar cane bagasse (SCB), wheat bran (WB), orange pulp and peel (OPP) and their combination (weight proportion 1:2:2 SCB/OPP/WB) were obtained using the line heat source ...
Field-dependent conductivity at low electric fields in pressed pellets of doped poly (3-methylthiophene): evidence of charge-density wave depinning
(Elsevier B.V., 2003-04-01)
Field-dependent conductivity at low electric fields was observed from low to room temperature in pressed pellets of doped poly(3-methylthiophene). The room temperature data showed good agreement with Bardeen's theory of ...
Effect of charge-spin separation on the conductance through interacting low-dimensional rings
(Elsevier Science, 2009-10)
We calculate the conductance through Aharonov-Bohm chain and ladder rings pierced by a magnetic flux which couples with the charge degrees of freedom. The system is weakly coupled to two leads and contains strongly interacting ...
Aluminum-induced stomatal closure is related to low root hydraulic conductance and high ABA accumulation
(2020-11-01)
Many studies ask how aluminum (Al) reduces the root growth, but as Al is mostly retained in the root system, physiological explanations for the also expected Al-induced decrease in stomatal conductance (gs) are unclear, ...
