Ce promoted Cu/γ-Al2O3 catalysts for the enhanced selectivity of 1,2-propanediol from catalytic hydrogenolysis of glucose

open access: yesCatalysis Communications, 2022
Ce promoted Cu/γ-Al2O3 catalysts were prepared with varying amounts of Cu (x = 0–10 wt%) and Ce (y = 0–15 wt%). The prepared catalysts were characterized and tested for the conversion of aqueous glucose (5 wt%) to 1,2-propanediol in a batch reactor.

Ethylene glycol poisoning [PDF]

open access: yesMedical Journal Armed Forces India, 2015
Ethylene glycol (EG) is a common constituent of anti-freeze, coolants and other solvents and is responsible for both inadvertent and intentional poisoning.1 Ethylene glycol poisoning may pose diagnostic difficulties if the history of ingestion is not volunteered, or if the presentation is delayed. The toxicity is because of biochemical features of high

Ultrasonic and volumetric behaviour of glycols with sodium ethylparaben in aqueous medium from T = 293.15 to 308.15 K at atmospheric pressure

open access: yesResults in Chemistry, 2020
Volumetric and acoustic analysis is set in motion to inspect the sodium ethylparaben interaction with ethylene glycol, and propylene glycol as a function of temperature. The estimation of apparent molar volume and apparent molar isentropic compression of

FORMULATION AND STABILITY OF HEPTAMINOL SUPPOSITORIES [PDF]

open access: yesBulletin of Pharmaceutical Sciences. Assiut University, 1984
The chemical stability of Heptaminol Base and of Heptaminol Hydrochloride was determined after shelf-life storage in an aqueous solution at room temperature. Under these conditions, the Base was found about 10.54 times more stable than the hydrochloride.

Ethylene signalling receptors and transcription factors over the grape berry development: gene expression profiling [PDF]

open access: yes, 2010
The ethylene signalling pathway has never been fully described in grapes. Regarded as a non-climacteric fruit, grape berry seems to ripen independently to ethylene, however 1-methylcyclopropene (1-MCP), a specific inhibitor of ethylene receptors has been

Relationship between Friction Coefficient, Viscosity and Compressibility of Polyethylene Glycol

open access: yesTribology Online, 2008
An ultrasonic liquid processor with the frequency of 20 kHz was used to cleave a principal chain in a polyethylene glycol molecule. The amount of the lubricant molecules cleaved by the ultrasonic disruption was evaluated by the kinematic viscosity ...

A dominant repressor version of the tomatoSl-ERF.B3gene confers ethylene hypersensitivity via feedback regulation of ethylene signaling and response components [PDF]

open access: yes, 2013
Ethylene Response Factors (ERFs) are downstream components of the ethylene signal transduction pathway, although their role in ethylene-dependent developmental processes remains poorly understood. As the ethylene-inducible tomato Sl-ERF.B3 has been shown

Ethylene Glycol Toxicity [PDF]

open access: yesMilitary Medicine, 2004
Ethylene glycol is an inexpensive, readily available substance that may be associated with accidental or intentional toxicity. Toxicity from this substance may be encountered in the military and civilian populations. Because it is highly toxic and can result in death if not treated appropriately, it is imperative to recognize the signs and symptoms of ...
