Nafion Spin Coating inside Nano/micro Structured Cathode for Three-phase Interface Control in Micro-dmfc
A high surface area and micro process integrated cathode for μ-DMFC is introduced in this study. CNTs growth inside micro structured cathode for catalyst support was employed for reaction surface increment, while liquid Nafion spun into radial arranged micro reaction holes controlled by centrifugal force was carried out to provide proper immersion ratio of CNTs in Nafion. The process is all int...
متن کاملHPLC separations with micro-bore columns using high-temperature water and flame ionization detection.
Previous work demonstrates that a flame ionization detector (FID) may be used as a detector for high-temperature water separation. However, the relatively high flow rate of the eluent required by standard high-performance liquid chromatography columns causes instability of the FID. In this work, micro-bore columns are packed with poly(styrene-divinylbenzene) (PRP-1) or Daiso gel octadecylsilane...
متن کاملA Self-Consistent Model for Negative Glow Discharge Lasers: The Hollow Cathode Helium Mercury Laser
A model for negative glow metal-vapor ion lasers that self-consistently describes the dynamics of the negative glow and the cathode sheath regions of the discharge has been developed. The model computes the electron energy distribution and the population of relevant excited states in the negative glow self-consistently with the charged particle fluxes and electric field distribution in the cath...
متن کاملAnalysis of Wood Pore Characteristics with Mercury Intrusion Porosimetry and X-ray Micro- Computed Tomography
The size and distribution of wood pores greatly influence its properties like density, thermal conductivity and permeability as well as acoustical property. Different techniques were developed to measure wood pore characteristic parameters. In this paper, mercury intrusion porosimetry (MIP) and X-ray Micro-computed tomography (μCT) were used to characterize pore characteristics of Populus L. wo...
متن کاملQuasar pairs with arcminute angular separations
We use the Véron-Cetty & Véron (2000) catalog (VV) of 13 213 quasars to investigate their possible physical grouping over angular scales 10′′ ≤ ∆θ ≤ 1000′′. We first estimate the number of quasar pairs that would be expected in VV assuming a random distribution for the quasar positions and taking into account observational selection effects affecting heterogeneous catalogs. We find in VV a stat...
