On the formaldehyde-bisulfite-hydroxymethanesulfonate equilibrium
Shen Dong,Purnendu K. Dasgupta +1 more
TL;DR: The dissociation constant for the aqueous equilibrium OHCH 2 SO 3 − = HCHO + HSO 3 − (where HCHO includes the hydrated form) has been determined via vapor pressure measurements to be 1.17 ± 0.14 × 10 −7 at pH 4 and 293 K, in excellent agreement with kinetic and spectroscopic measurements as discussed by the authors.
Journal ArticleDOI
Oxygen-independent poly(dimethylsiloxane)-based carbon-paste glucose biosensors
TL;DR: Several silicone oils have been assessed and compared as an internal source of oxygen in connection to their use as binders for carbon-paste glucose biosensors and indicate favorable dynamic properties with no carry-over effects over the physiological and pathophysiological range.
Journal ArticleDOI
Liquid Chromatographic Arsenic Speciation with Gas-Phase Chemiluminescence Detection
TL;DR: This analyzer demonstrates the robustness of the CL detection system for arsenic and provides an affordable alternative to atomic spectrometry for use as a detector after chromatographic speciation.
Journal ArticleDOI
Measurement of gaseous hydrogen peroxide with a liquid core waveguide chemiluminescence detector
TL;DR: In this article, a simple luminol chemiluminescence (CL) measurement of H 2 O 2 with a liquid core waveguide (LCW)-based instrument is presented.
Journal ArticleDOI
Entropy driven spontaneous formation of highly porous films from polymer-nanoparticle composites.
Venumadhav Korampally,Minseong Yun,Thiruvengadathan Rajagopalan,Purnendu K. Dasgupta,Keshab Gangopadhyay,Shubhra Gangopadhyay +5 more
TL;DR: A simple method for the rapid fabrication of nanoporous materials from colloidal dispersions of Polymethyl Silsesquioxane nanoparticles is described and the entropic gain experienced by the nanoparticles in this rubric is harnessed to fabricate novel highly porous films composed of nanoparticles.
