“…The cellulose films reconstituted from imidazolium ILs were also explored as a platform for noncovalent and covalent immobilization of several enzymes. 38,88,[104][105][106] The procedures for producing enzyme-containing films differed from each other by the cellulose content, conditions of its dissolution in ILs, and the features of adding biocatalysts into the matrix. Laccase from Rhus vernicifera was the first enzyme, immobilized into cellulose films.…”

“…Conditions of noncovalently and covalently immobilizing an enzyme into/on the cellulose films are under detailed investigation. Although there have been some attempts to determine the enzyme substrates (syringaldazine, 38,104,105 guaiacol, 70 aryldiamines, 88 catecholamines, 88 and o-nitrophenyl-β-D-galactopyranoside), 106 the practical use of such kinds of biosensing materials seems to be a future goal. Currently, there exists only one cellulosebased film sensor with a noncovalently immobilized catalytic indicator system of pyronin B-Mn(II)-sodium dodecyl sulfate for fluorescent determination of artemisinin in pharmaceuticals.…”

“…ILs can dissolve inorganic gases (O2, CO2, CO, SO2, NO2, H2S, etc. ), 24,27 silicon alkoxides (tetramethoxysilane, TMOS; tetraethoxysilane, TEOS; methyltrimethoxysilane, MTMOS), 28 mono-and polysaccharides (carbohydrates, starch, cellulose, chitin, chitosan, guar gum, and xanthan gum), 10,[29][30][31][32] natural organic materials (silk 17 and wood 29,33,34 ), some synthetic polymers, 35,36 enzymes, [37][38][39] etc. The listed substances can serve either as matrix materials (natural and synthetic polymers) or recognition elements (dyes, complexes, and biocatalysts), and target compounds (gases) for optical sensing platforms.…”

This paper reviews the primary literature reporting the use of ionic liquids (ILs) in optical sensing technologies. The optical chemical sensors that have been developed with the assistance of ILs are classified according to the type of resultant material. Key aspects of applying ILs in such sensors are revealed and discussed. They include using ILs as solvents for the synthesis of sensor matrix materials; additives in polymer matrices; matrix materials; modifiers of the surfaces; and multifunctional sensor components. The operational principles, design, texture, and analytical characteristics of the offered sensors for determining CO2, O2, metal ions, CN -, and various organic compounds are critically discussed. The key advantages and disadvantages of using ILs in optical sensing technologies are defined. Finally, the applicability of the described materials for chemical analysis is evaluated, and possibilities for their further modernization are outlined.

As a molecular weight (M ) estimation method for cellulose in ionic liquid solution, fitting procedure of dynamic viscoelastic data to Rouse-Zimm (RZ) model with a correction term (LT term), introduced by Osaki et al. and examined for standard polystyrene samples, is examined in this study. Since the RZ model calculation with and without LT term for loss modulus G" almost coincide, the data are first fitted to RZ model to get the best fit of G" by using M as a single fitting parameter, while fixing other parameters from experimental conditions and using experimentally determined relaxation time t RZ . Then the LT term, calculated from intrinsic viscosity [h ] and two adjusting parameters, is employed to judge the appropriateness of the estimation of molecular weight by further fitting storage modulus G'. The measured G' and G" can be well fitted with RZ model plus LT term in the terminal region though small discrepancy in the transition region was observed. The estimated M showed ±10% error due to ±15% error of t RZ . It is concluded that this procedure is useful when t RZ can be determined within a small error. The estimated M can be used at least for the comparison of cellulose/IL solutions differently prepared.

“…For example, the incorporation of electrolyte components in the anodic films was enhanced by decreasing water content, 16 and a film consisting of a nonstoichiometric compound (AlO x/2 F 3¹x ) was formed when an electrolyte such as LiBF 4 or LiPF 6 /PC+DME solution was used. 17 Room-temperature ionic liquids (IL) are attracting considerable attention as reaction solvents, 18 extraction solvents, 19 and electrolyte materials 20,21 as a result of their remarkable properties, including negligibly small vapor pressure, thermal stability, and high ionic conductivity. The most promising applications have been as electrolytes for aluminum electrolytic capacitors and lithium ion batteries.…”

Formation of Al2O3 Film and AlF3 Containing Al2O3 Film by an Anodic Polarization of Aluminum in Ionic Liquids

et al. 2012

Anodic polarization of aluminum in three kinds of ionic liquids was studied by the constant-voltage rising rate method and constant-current method, with characterization by X-ray photoelectron spectroscopy. Both the capacity for passive-layer formation and the composition varied depending on the ionic liquid, applied voltage and holding time. A passive film consisting of Al 2 O 3 and AlF 3 in which the concentration of AlF 3 became the highest at the Al 2 O 3 /Al interface was formed in 1-butyl-3-methylimidazolium trifluoromethylacetate (BMIm-TFA) at 40 V. In the case of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide (BMIm-TFSA), no passive film was formed at 40 V. However, a passive film in which the concentration of AlF 3 reached its maximum at the electrolyte/Al 2 O 3 interface was formed at 10 V, and the layer composition changed to pure Al 2 O 3 when held at 10 V for 20 min. On the contrary, pure homogeneous Al 2 O 3 film was formed in 1-ethyl-3-methylimidazolium lactate (EMIm-LAC) at 40 V. Although the oxygen source of the oxidation reaction was thought to be the small amount of water contained in the ionic liquids, the anion component of the ionic liquids appears to have had an important effect on the ability to form a passive layer and its composition.
