Mixtures of two or more pesticides are very common in contemporary agriculture. However, changes their efficacy biological activity, such as synergism and antagonism, phytotoxicity, persistence, toxicity to non-target organisms, may occur a consequence. This study was conducted order evaluate the compatibility insecticides (cyantraniliprole - Exirel, chlorantraniliprole Coragen 20 SC), fungicid...

The vaporisation of ionic liquids has been investigated using temperature programmed desorption (TPD) and ultra-high vacuum (UHV) distillation. 1-Alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquids, [C(n)C(1)Im][Tf(2)N] (n = 2, 8), have been distilled at UHV and T > 500 K in a specially designed still. The distillation process yielded spectroscopically pure ionic liquid di...

Electrochemical SERS (E-SERS) was used for the first time to study the interfacial behavior of a class of pyridinium-based biodegradable ionic liquids at a silver nanoparticle (AgNP) electrode surface. An isomeric series of ionic liquids (IL) based on 3-butoxycarbonyl-1-methylpyridinium bis(trifluoromethanesulfonyl)imide were prepared, which have demonstrable biodegradability. It was found that...

A validated ion chromatographic method was developed and applied for the determination of the maximum solubility of pyridinium ionic liquids in several aromatic solvents. Elution was performed on a Metrosep C3-150 prototype column at 40°C with acetonitrile-water at a flow rate of 1.0 mL min(-1). Mixtures of pyridinium ionic liquids and aromatic solvents were diluted with acetonitrile and aceton...

We study the low-temperature thermodynamics of weakly-interacting uniform liquids in one-dimensional attractive Bose-Bose mixtures.~The Bogoliubov approach is used to simultaneously describe quantum and thermal fluctuations. First, we investigate detail two different mechanisms driving liquid-to-gas transition, dynamical instability evaporation, draw phase diagram. Then, compute main thermodyna...

This article summarizes the results of IUPAC Project 2002-005-1-100 (Thermodynamics of ionic liquids, ionic liquid mixtures, and the development of standardized systems). The methods used by the various contributors to measure the thermophysical and phase equilibrium properties of the reference sample of the ionic liquid 1-hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]amide and its mi...

Ionic liquids (ILs) are organic salts that have melting points around room temperature. They have received tremendous attention recently due to their low volatility and subsequent potential to reduce air pollution if used as replacements for volatile organic solvents. As a result, they have the potential to be used in a wide variety of chemical processing applications, including as solvents for...

Ionic liquids are promising candidates for novel electrolytes as they possess large electrochemical and thermodynamic stability offer a high degree of tunability. As purely-ionic electrolyte without neutral solvent exhibit characteristic structures near electrified interfaces in the bulk, both being described theoretically via separate frameworks methodologies. We present holistic continuum the...

We first review the development of a frequency domain quasi-optical terahertz (THz) chemical sensing and imaging platform consisting of a quartz-based microfluidic subsystem in our previous work. We then report the application of this platform to sensing and characterizing of several selected liquid chemical samples from 570–630 GHz. THz sensing of chemical mixtures including isopropylalcohol-w...
