A portable vacuum interface allowing direct probing of the electrode-electrolyte interface was developed. A classical electrochemical system consisting of a gold working electrode, platinum counter electrode, platinum reference electrode, and potassium iodide electrolyte was used to demonstrate real-time observation of the gold iodide adlayer on the electrode and chemical species as a result of...

The passive mode locking of an argon-ion-pumped energy-transfer cw dye laser operating in the near infrared is reported. The dyes 1,1'-diethyl-4,4'-carbocyanine iodide and 1,1'-diethyl-2,2' -dicarbocyanine iodide were used separately to mode lock a gain medium comprising the dyes DCM and Rhodamine 700. Subpicosecond pulses were generated from 732 to 761 nm in a simple linear cavity, and pulses ...

The asymmetric unit of the title structure, C3H11NOP(+)·I(-)·C3H10NOP, consists of one (di-methyl-phosphor-yl)methanamine (dpma) mol-ecule, one (di-methyl-phosphor-yl)methanaminium (dpmaH) ion and one iodide counter-anion. In the crystal, medium-strong to weak N-H⋯O and N-H⋯N hydrogen bonds connect dpmaH cations and dpma mol-ecules into strands along [001]. The iodide counter-anions form only v...

BACKGROUND Perchlorate and thiocyanate interfere with iodide uptake at the sodium-iodide symporter and are potential disruptors of thyroid hormone synthesis. Perchlorate is a common contaminant of water, food, and human milk. Although it is known that iodide undergoes significant diurnal variations in serum and urinary excretion, less is known about diurnal variations of milk iodide levels. O...

Lactoperoxidase, in the presence of hydrogen peroxide and iodide is cytotoxic for human and mouse lymphoid cells, and human erythrocytes. Myeloperoxidase, in amounts equivalent to 1.5 x 10(6) neutrophils, readily replaces lactoperoxidase, and allows the substitution of the iodide ion by chloride. The myeloperoxidase-mediated reaction is rapid, and highly efficient, leading to 85-90% cell death ...

In the title compound, C(14)H(14)N(+)·I(-), the cation exists in an E configuration with respect to the ethenyl bond and is slightly twisted, the inter-planar angle between the pyridinium and phenyl rings of the cation being 4.8 (2)°. In the crystal packing, the cations are stacked in an anti-parallel fashion along the a axis by a π-π inter-action involving both pyridinium and phenyl rings; the...

The structure of catena-poly[[potassium-tri-μ-di-methyl-acetamide-κ(6) O:O] iodide], {[K(C4H9NO)3]I} n , at 120 K has trigonal (P-3) symmetry. The structure adopts a linear chain motif parallel to the crystallographic c axis. Two crystallographically independent K(+) cations are present in the asymmetric unit located on threefold rotoinversion axes at [0, 0, 0] and [0, 0, 1/2] and are bridged b...

The title compound, [Cu(6)I(6)(C(2)H(6)N(2)S)(6)], was obtained from the reaction of copper(I) iodide with N-methyl-thio-urea (Metu) in equimolar amounts in acetonitile. The complex consists of two six-membered trinuclear Cu(3)S(3)I(3) cores that combine through triply bridging Metu, forming a hexa-nuclear core which has -3 symmetry. The Cu(II) atom is coordinated by three S atoms of Metu and o...

A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, N-methyl-2,2'-dipyridinium iodide and N,N'-dimethyl-2,2'-dipyridinium diiodide, were used as the visualization reagents, forming ion-pair complexes with the sulfonate surfactants. This a...
