Nitrogen-doped carbon materials with controllable morphologies were prepared via a soft template method using chitosan as the carbon and nitrogen source and F127 or ionic liquid as the template. The performance of the materials as electrodes and adsorbents for carbon dioxide removal were evaluated. Carbon spheres (CSs) with developed micropore structures were obtained without a template, whereas a tubular structure (CSF) containing mesopores with long-range order was obtained using F127. Layered carbon (CSI) containing micro-/mesopores with short- and long-range order was obtained using an ionic liquid. The samples exhibited graphite-like structure and the soft template increased the graphitization degree. Nitrogen existed mainly in the form of pyridine and pyridone groups in CSs and CSF and as pyridine, pyridone, and quaternary groups in CSI. The specific capacitances of CSs, CSF, and CSI were 144, 161, and 178 F g−1, respectively, at a current density of 1.0 A g−1 in 1 M sulfuric acid. The carbon dioxide adsorption capacities of CSs, CSF, and CSI were 142, 73, and 115 mg g−1, respectively; CSs displayed the highest value because of its developed micro- and ultramicroporous structure. Our results indicated that these carbon materials with various morphologies can be used as both electrodes and adsorbents.

“…A value of the same order was obtained for 1-dodecyl-3-methylimidazolium 3-hydroxy-2naphthoate in water (α = −4.8 × 10 −3 K −1 ). 47 However, for mixed bilayers of dioleoylphosphatidylserine with long-chain alcohols 48 and for 1,3-didecyl-2-methylimidazolium chloride with decanol 49 the values of α are −1 × 10 −3 and −1.3 × 10 −3 K −1 , respectively. These data suggest that there are important differences in the thermal expansivity of bilayers formed by single-and double-tailed surfactants.…”

The lyotropic behavior of the ternary system formed by 1-tetradecyl-3-methylimidazolium chloride, 1-decanol, and water is investigated. A lamellar mesophase is formed for a wide range of compositions and is characterized by polarized optical microscopy, low-temperature scanning electron microscopy, small- and wide-angle X-ray scattering with synchrotron radiation, and differential scanning calorimetry. This phase presents onionlike structures. Two lamellar structures are formed: an L mesophase between 25 and 50 °C, with an isobaric thermal expansivity of the bilayer thickness of -3.2 × 10 K, and a lamellar gel phase, when the temperature decreases below 25 °C. This new medium is employed to perform in situ X-ray-initiated polymerization of N-isopropylacrylamide. When the monomer is incorporated in the lamellar structure, it is distributed between the water layer and bilayer interface and its polymerization can be followed by variations in the diffractograms with time.

“…Previous works [17] attributed the above behavior to changes in the liquid structure. The presence of lamellar lyotropic liquid crystal phases (arranged in parallel layers), favored at the highest shear rates, could explain the aforementioned behavior [27]. The apparent viscosity of the ternary systems at a constant shear rate increased (about 20 times) with increasing [ProC 4 ]DS content (from 20 to 84 wt %, T1-T6) (Supporting Information Tab.…”

Thermo‐Rheology of a Proline‐Based Surface‐Active Ionic Liquid: Mixtures with Water and n‐Octane

Surfactant flooding is one of the most promising techniques to recover oil from unprofitable reservoirs. Surface-active ionic liquids can overcome the limitations of the current surfactants. The rheology of the injecting solutions and the formed slugs is critical in the evaluation of an enhanced oil recovery process. The thermorheological behavior of a biodegradable surface-active ionic liquid, [ProC 4 ]DS, and the corresponding binary and ternary mixtures with water and n-octane was studied. All flow curves exhibited shear-thinning and thixotropic behavior. The viscoelastic behavior of the ternary samples depended strongly on the [ProC 4 ]DS content. Three different regions were identified: typical liquid-like behavior, weak gel, and true gel. The thermal profiles indicated that the tested systems were fully thermoreversible.
