STANDARD IODINE SOLUTION FOR SULPHUR DETERMINATIONS.

modelling of westinghouse and sulphur-iodine water splitting cycles for hydrogen production

hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

High-performance iodine fiber frequency standard.

We have constructed a compact and robust optical frequency standard based around iodine vapor loaded into the core of a hollow-core photonic crystal fiber (HC-PCF). A 532 nm laser was frequency locked to one hyperfine component of the R(56) 32-0 (127)I(2) transition using modulation transfer spectroscopy. The stabilized laser demonstrated a frequency stability of 2.3×10(-12) at 1 s, almost an o...

Fuzzy Sets for Assessing the Profitability of Hydrogen Production by the Sulphur-iodine Thermochemical Cycle

A possibility to produce hydrogen without greenhouse gas emissions is to couple a thermochemical cycle with a nuclear reactor. Among the various thermochemical cycles, the Sulphur/Iodine process is currently the most studied. The production cost of hydrogen from this process is the sum of several cost accounts which are not at present known in any satisfactory way. In this paper we present an a...

Chemistry of +1 Iodine in Alkaline Solution

Zinc lozenges: cold cure or candy? Solution chemistry determinations.

Common colds were shortened by 7 days in a 1984 clinical trial using zinc gluconate throat lozenges each 2 h. Between then and 2004, 10 other double-blind, placebo-controlled clinical trials showed widely varying results. This re-analysis of these trials presents solution chemistry methods to elucidate differences in efficacy. Statistically significant correlation was shown between total daily ...
