acid methyl ester (TBAMES) and tetra-n-butylphosphonium dodecylsulphate (TBPDS) were synthesized. Though all the surfactants are ionic in nature, they show the clouding phenomenon on heating. The effect of temperature on the solution behaviour (micellization and clouding) of the synthesized surfactants was studied by conductometry, dynamic light scattering (DLS), nuclear magnetic resonance (NMR), small
An ion-selective electrode of improved performance, particularly in mixed solvent systems, for example in analysis of ionic surfactants, consists of a solid support (1), preferably spectrographically pure graphite, on which is deposited a polyvinylchloride membrane (5) containing a minor proportion of an electroactive substance.
Provided herein are systems and methods for processing and analyzing nucleic acids and other biomolecules. Methods may include processing nucleic acid molecules in an emulsion of droplets. Methods of analyzing nucleic acid molecules may include coupling nucleic acids to a bead or other support. Methods may include analysis of nucleic acid molecules using a redox mediator. In some cases, analysis of the nucleic acid molecule includes determining a nucleotide sequence of the nucleic acid molecule.
