We introduce a two-dimensional method for mass spectrometry in solution that is based on the interaction between a nanometer-scale pore and analytes. As an example, poly(ethylene glycol) molecules that enter a single alpha-hemolysin pore cause distinct mass-dependent conductance states with characteristic mean residence times. The conductance-based mass spectrum clearly resolves the repeat unit...

Acute ethylene glycol ingestion classically presents with high anion gap acidosis, elevated osmolar gap, altered mental status, and acute renal failure. However, chronic ingestion of ethylene glycol is a challenging diagnosis that can present as acute kidney injury with subtle physical findings and without the classic metabolic derangements. We present a case of chronic ethylene glycol ingestio...

1. Oxalate crystals may occur in the CSF with ethylene glycol poisoning or primary hyperoxaluria type 1. Ethylene glycol is metabolized by alcohol dehydrogenase to form glycolic and oxalic acids. 2. Serum electrolytes and osmolality can be measured, and the anion and osmolar gaps can be calculated. Ethylene glycol poisoning is associated with an increased osmolar gap and increased anion gap met...

Although an uncommon cause of death in Great Britain, ethylene glycol poisoning is potentially serious in that renal and cardiopulmonary failure and central nervous system dysfunction can occur when doses of the order of 100 ml or more are ingested. A case is described in which a child who swallowed approximately 100 ml of ethylene glycol was treated by prolonged peritoneal dialysis. In additio...

We report zero-field NMR measurements of a viscous organic liquid, ethylene glycol. Zero-field spectra were taken showing resolved scalar spin-spin coupling (J-coupling) for ethylene glycol at different temperatures and water contents. Molecular dynamics strongly affects the resonance linewidth, which closely follows viscosity. Quantum chemical calculations have been used to obtain the relative...

in this study, the natural convection heat transfer of variable properties al2o3-eg-water nanofluid in a differentially heated rectangular cavity has been investigated numerically. the governing equations, for a newtonian fluid, have been solved numerically with a finite volume approach. the influences of the pertinent parameters such as ra in the range of 103-107 and volume fraction of nanopar...

Non-aqueous Pickering emulsions of 16-240 μm diameter have been prepared using diblock copolymer worms with ethylene glycol as the droplet phase and an n-alkane as the continuous phase. Initial studies using n-dodecane resulted in stable emulsions that were significantly less turbid than conventional water-in-oil emulsions. This is attributed to the rather similar refractive indices of the latt...

OBJECTIVES Ethylene glycol ethers and their acetates are widely used in industry, because of their hydrophilic and simultaneously lipophilic properties. Ethylene glycol ethers and their acetates are mainly metabolised to alkoxyacetic acids, but there is also a minor pathway through ethylene glycol to oxalic acid. The main pathway of ethylene glycol ethers is associated with significant clinical...

Calculation of excess quantities of ethylene glycol + water binary fluid systems at seven absolute temperatures (293.15 to 353.15) K from experimentally determined values of density and shear viscosity were presented in previous work. The examination of related functions beside the quality of correlation from several equations on these experimental values has also been reported. Considering...

The discovery that ethylene glycol monomethyl ether (EGME) could affect the testis and the developing fetus in laboratory animals prompted further work to understand the effect of EGME and to examine additional glycol ethers to see if they showed EGME's reprotoxicity. Propylene glycol monomethyl ether (PGME) was shown not to cause testicular atrophy or to affect the development of rats at 600 p...
