Identification of the molecular carriers of diffuse interstellar bands (DIBs) requires gas phase electronic spectra of suitable candidate structures. Recording the spectra of these in the laboratory is challenging because they include large, carbon-rich molecules, many of which are likely to be ionic. The electronic spectra of ions are often obtained using action spectroscopy methods, which can induce small perturbations to the absorption characteristics and hinder comparison with astronomical observations.

Pyrene fluorescence in aqueous solutions of two surface active ionic liquids, namely, 1-decyl-3-methylimidazolium chloride, and 1-hexadecyl-3-methylimidazolium chloride was investigated in presence of a biopolymer sodium alginate. The principal objective of this study was to explore the influence of the length of the hydrocarbon tails of these surface active ionic liquids on the possible location of the probe (pyrene) molecules in presence of the additive. While an abrupt decrease in the values of the ratio of the intensity of the first vibronic band to that of the third band of pyrene emission spectrum with concentration was observed for 1-hexadecyl-3-methylimidazolium chloride in presence of sodium alginate like the polymer-free case reported earlier, there was a peculiar reversal for 1-decyl-3-methylimidazolium chloride + sodium alginate.

Heteroprotein complex coacervation has potential for a wide range of applications. However, the sensitivity of coacervates to slight changes in physico-chemical conditions may constitute a technological barrier for their development and deserves to be better understood. In this study, the rheological properties of β-lactoglobulin/lactoferrin (βLG/LF) heteroprotein complex coacervates were investigated with respect to narrow changes of temperature (5-40 °C) and ionic strength (0 to 10mM added NaCl).

Marine sulfated polysaccharides constitute a class of bioactive polymers commonly found in cell walls of macroalgae. Among these macromolecular substances, fucoidans, ulvans, and carrageenans have attracted considerable attention providing interesting therapeutic properties affected by a combination of various structural factors, such as sulfation pattern, molecular weight, monosaccharide composition, and glycosidic linkages. Remarkably, chemical modification, enzymatic hydrolysis and crosslinking are promising approaches for developing the application of these polysaccharides through enhancement and/or addition of new biological properties.

Compared to liquid electrolytes, gel polymer electrolytes (GPEs) offer enhanced safety and represent an up-and-coming option for high-energy-density lithium metal batteries (LMBs). However, several challenges hindered the practical application of GPEs for LMBs, such as low ionic conductivity at room temperature, decomposition at high voltage, and poor interfacial compatibility with lithium anode. In this study, a non-flammable fluorinated GPE was synthesized using 2,2,2-trifluoroethyl acrylate (TFEA) and ethoxylated trimethylolpropane triacrylate (ETPTA) as precursor materials, with succinonitrile (SN) incorporated as a plasticizer and a dual-salt system of lithium bis(trifluoro-methane) sulfonimide and lithium difluoroxalate borate.
