Polyfluoroalkyl substances (PFAS) are a family of highly toxic fluorinated compounds used in hundreds of everyday consumer products. These chemicals are persistent in the environment and in the human body – meaning they don’t break down easily and they can accumulate over time. There is eviden...
The present invention relates to ionic compounds of quaternary ammonium cations with anions of preservative acids, which for the preservation of, for example, cosmetics, washing - and cleaners, pharmaceutical preparations, consumer articles or as preservatives, during and disinfecting agent in industrial ...
After printing upon solvent exchange with water, the quaternary ammonium groups on QCh will fully disassociate due to the property of quaternary ammonium compounds to fully disassociate in water (Bureš, 2019), and it will act as an ionic crosslinker for the supramolecular acrylate hydrogels. ...

metallic compounds in organisms results in cellular toxicity due to the formation of reactive oxygen species (ROS), which are neutralised by antioxidant defences, antioxidant substances (glutathione, vitamin E and carotenoids) and enzymes (catalase -CAT, glutathione reductase - GR, and superoxide ...
All test and reference compounds were tested at pH 7; in addition, the C12 carboxylate was also tested at pH 2 and pH 9. Standard aqueous buffer solutions of pH 2, 7 and 9 were prepared. Saturated aqueous andn-octanol phases for logKowslow-stirring studies were prepared by stirring over...
may include simple mixtures of two or more compounds, and optionally include reaction or decomposition products formed in situ. LTILs useful in connection with the present invention may be prepared by combining two or more individual component compounds, which are usually solid under ambient conditions...
The reactive functional groups on the cation allow the ionic compound to cross-link with a host charge transport compound. Such ionic compounds may have various properties, such as thermodynamic stability, hole injection/transport capabilities, electrochemical durability, and/or solubility in organic solv...
the sensor can be incorporated in a breath analysis detector to analyze and determine what a person has been exposed to or if they have a disease. A breath analysis detector can detect volatile compounds in breath, such as alcohol, ketones and other volatile compounds that can indicate physiolog...
Suitable Z alkyl components also include mixtures of such compounds, and where mixtures of alkyl components are used the ranges of carbon atoms indicated above are based on the weight average of the mixture. Exemplary commercial mixtures include alcohols sold under the tradenames Alfol® and ...
