A new method to measure oxygen concentration in air-saturated organic solvents and binary mixtures has been developed. The methodology relies on the ability of HPLC columns to retain the molecular oxygen contained in different types of solvents which are injected into the system at 298.15 K. The outlet of the HPLC is coupled with an optical oxygen sensor which continuously measures changes in oxygen partial pressure.

The determination of solubility parameters for solutes represents a challenging mathematical problem of locating the central tendency of solvent affinity based on a limited set of data taken from expe...
The dielectric nature of organic ligands capping semiconductor colloidal nanocrystals (NCs) makes them incompatible with optoelectronic applications. For this reason, these ligands are regularly subst...
Mycobacterium sp. can convert steroids such as β-sitosterol, campesterol, and cholesterol into commercially interesting products. In aqueous systems, the biocatalysis is limited by the low solubility...
The ortho, meta and para isomers of 9,10-dipyridylanthracene 1 have been synthesized and converted into their endoperoxides 1-O2 upon oxidation with singlet oxygen. The kinetics of this reaction can b...
Using p-phenylenediamine as a precursor, p-carbon dots (p-CDs) with strong red-light emission were encapsulated into a metal-organic framework (MOF) followed by introduction of green light-emitting Tb...

In Quebec, thousands of workers are concomitantly exposed to heat and chemical compounds. Exposure to heat induces physiological responses that help maintaining a stable body temperature. ...
Comparison of an optical method to continuously measure blood pressure against an invasive arterial catheter.
The study aims to evaluate the hypothesized benefits of a systematic organic diet for children, over those of a conventional diet. The specific objectives of this study are to: i) Demonstr...
Many grafts placed for dialysis access fail which causes patients to undergo additional operations, decreases their quality of life, and increases health care costs. The purpose of this s...
An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.
A measure of the ability of a substance, such as a food, to quench oxygen free radicals in vitro.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
Homogeneous liquid preparations that contain one or more chemical substances dissolved, i.e., molecularly dispersed, in a suitable solvent or mixture of mutually miscible solvents. For reasons of their ingredients, method of preparation, or use, they do not fall into another group of products.
Organic compounds having two alkyl or aryl groups bonded to an oxygen atom, as in the formula R1–O–R2.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
