Electrochemical Sensors with Screen Printed Ag|AgCl|KCl Reference Electrodes
This paper presents the printed thick film Ag|AgCl|KCl reference electrodes for electrochemical or biosensors application and their electrochemical and analytical performance. The reference electrode exhibits a stable potential against standard glass reference electrode with a potential difference of 5 mV in the deionized water. The anodic and cathodic peak current of the electrode increase with the increase in scan rate in the range of 25-150 mVs-1. The open circuit potential response of thick film reference electrode in the NaCl concentrations range (30-100 mM) was measured and it shows a stable potential in each test solution. The fabricated reference electrode shows an excellent application for an electrochemical pH sensor
The Hierarchical Reference Theory as applied to square well fluids of variable range
Continuing our investigation into the numerical properties of the
Hierarchical Reference Theory, we study the square well fluid of range lambda
from slightly above unity up to 3.6. After briefly touching upon the core
condition and the related decoupling assumption necessary for numerical
calculations, we shed some light on the way an inappropriate choice of the
boundary condition imposed at high density may adversely affect the numerical
results; we also discuss the problem of the partial differential equation
becoming stiff for close-to-critical and sub-critical temperatures. While
agreement of the theory's predictions with simulational and purely theoretical
studies of the square well system is generally satisfactory for lambda greater
than about 2, the combination of stiffness and the closure chosen is found to
render the critical point numerically inaccessible in the current formulation
of the theory for most of the systems with narrower wells. The mechanism
responsible for some deficiencies is illuminated at least partially and allows
us to conclude that the specific difficulties encountered for square wells are
not likely to resurface for continuous potentials.Comment: 15 pages LaTeX/RevTeX, 3 tables, 4 figures. Also see

Self-accelerating solutions in massive gravity on an isotropic reference metric
Within the framework of the recently proposed ghost-free massive gravity, a
cosmological constant-type self-accelerating solution has been obtained for
Minkowski and de Sitter reference metrics. We ease the assumption on the
reference metric and find the self-accelerating solution for the reference
metric respecting only isotropy, thus considerably extending the range of known
solutions.Comment: 4 pages; matches the published version in Phys. Rev.
