Benedetto, Antonio published the artcileAbsorption of the [bmim][Cl] Ionic Liquid in DMPC Lipid Bilayers across Their Gel, Ripple, and Fluid Phases, Computed Properties of 79917-90-1, the publication is Journal of Physical Chemistry B (2022), 126(17), 3309-3318, database is CAplus and MEDLINE.

Lipid bilayers are a key component of cell membranes and play a crucial role in life and in bio-nanotechnol. As a result, controlling their physicochem. properties holds the promise of effective therapeutic strategies. Ionic liquids (ILs)-a vast class of complex organic electrolytes-have shown a high degree of affinity with lipid bilayers and can be exploited in this context. However, the chem. physics of IL absorption and partitioning into lipid bilayers is yet to be fully understood. This work focuses on the absorption of the model IL [bmim][Cl] into 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) lipid bilayers across their gel, ripple, and fluid phases. Here, by small-angle neutron scattering, we show that (i) the IL cations are absorbed in the lipid bilayer in all its thermodn. phases and (ii) the amount of IL inserted into the lipid phase increased with increasing temperature, changing from three to four IL cations per 10 lipids with increasing temperature from 10 °C in the gel phase to 40 °C in the liquid phase, resp. An explicative hypothesis, based on the entropy gain coming from the IL hydration water, is presented to explain the observed temperature trend. The ability to control IL absorption with temperature can be used as a handle to tune the effect of ILs on biomembranes and can be exploited in bio-nanotechnol. applications.

Zhang, Zeyu published the artcileSynthesis of renewable soybean protein and acrylate copolymers via ATRP in ionic liquid, COA of Formula: C8H15ClN2, the publication is Industrial Crops and Products (2022), 114720, database is CAplus.

In this paper, acrylate and glycidyl methacrylate (GMA) were grafted onto the main chain of soy protein isolate (SPI) in 1-butyl-2,3-dimethylimidazole chloride ionic liquid ([BDMIM][Cl]), to prepare a renewable soy protein graft copolymer via atom transfer radical polymerization (ATRP). The effect of unfolding degree of soy protein structure on pretreated SPI was studied via Fourier-transform IR spectroscopy (FT-IR), hydrogen NMR spectroscopy (¹ H NMR), surface tension (ST) and contact angle (CA) measurements. The results of FT-IR, ¹ H NMR and energy dispersive spectrometry (EDS) indicated the successful synthesis of 2-bromoisobutyryl-functionalized SPI. The anal. of FT-IR and ¹H NMR spectra showed that the soybean protein graft copolymer was successfully synthesized. In addition, the grafting of acrylate onto soybean protein enhanced the hydrophobicity of the copolymer, and the static contact angle was above 90°. Differential scanning calorimetry (DSC) anal. revealed that the thermal stability of pretreated SPI was reduced. The new glass transition temperature in the copolymers also proved the successful synthesis of the copolymers. The tensile strength of the carbon fiber multifilament infiltrated with the copolymers was improved, indicating their potential application in the reinforcement of carbon fiber material.

A review. Ionic liquids (ILs) are powerful media for the modification and functionalization of cellulose. This review article discusses the preparation of cellulosic soft and composite materials through the dissolution and gelation of cellulose with ILs. Based on the fact that the IL, 1-butyl-3-methylimidazolium chloride (BMIMCl) forms a cellulosic ion gel, the gel formation process has been employed to prepare a variety of cellulosic materials, of which the following are examples. The gel is converted into a thermoplastic composite film. The cellulose/BMIMCl composite film is reinforced with self-assembled chitin nanofibers. Solutions of cellulose in BMIMCl are converted into hydrogels, organogels, or organic solutions Binary ion gels of cellulose with other natural polysaccharides, such as starch, chitin, and hydrocolloid polysaccharides, are fabricated using BMIMCl and other ILs. The binary ion gels are converted into composite materials, such as films and fibers.

Watanabe, Hironobu published the artcileRole of the Counteranion in the Stereospecific Living Cationic Polymerization of N-Vinylcarbazole and Vinyl Ethers: Mechanistic Investigation and Synthesis of Stereo-Designed Polymers, COA of Formula: C8H15ClN2, the publication is Macromolecules (Washington, DC, United States) (2022), 55(11), 4378-4388, database is CAplus.

The effects of counteranions in the cationic polymerization of N-vinylcarbazole (NVC) and vinyl ethers were investigated to develop guidelines for stereospecific living cationic polymerization The counteranion structure, such as the charge number, metal center, and ligand, was systematically examined using the CF₃SO₃H/onium halide/metal halide initiating system. As a result, the electronic properties rather than the steric bulkiness of the counteranion were demonstrated to be key to stereoregulation during the polymerization of N-vinylcarbazole. Fine-tuning the stereoregularity of the resultant polymers was achieved (mm = 45-95%) while maintaining the living nature of polymerization Computational anal. indicated that the stereoregulation was attributed to electrostatic interactions between the counteranion and pendant aromatic rings. These findings also allowed stereospecific polymerization of vinyl ethers containing an aromatic ring in the pendant. Moreover, the successful synthesis of “stereo-designed” polymers, such as stereoblock and stereocontrolled block copolymers, was achieved by appropriately designing counteranions for living cationic polymerization

Kurtoglu-Oztulum, Samira F. published the artcileThermal stability limits of imidazolium, piperidinium, pyridinium, and pyrrolidinium ionic liquids immobilized on metal oxides, Safety of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Molecular Liquids (2022), 119804, database is CAplus.

Twenty-nine different ionic liquids (ILs) consisting of imidazolium, pyridinium, piperidinium, and pyrrolidinium cations and I^–, Cl^–, Br^–, PF^–₆, BF^–₄, [DCA]^–, and [NTf₂]^– anions were immobilized on MgO and SiO₂. Their short-term thermal stability limits were investigated by thermogravimetric anal. and compared with those of the corresponding bulk ILs. Data showed that the thermal stability limits of ILs change significantly when the ILs are immobilized on metal oxides. These changes were evaluated based on the structural interactions determined by IR spectroscopy. Systematic structural differences were considered to investigate the factors affecting the thermal stability of bulk ILs, and their counterparts immobilized on MgO and SiO₂. These structural changes were the change in the alkyl chain length, the methylation on C2 site in imidazolium ILs, the change in substituent position in the pyridinium ring, the change in the anion, and the change in the IL family. The strongest factor controlling the thermal stability limits of both bulk ILs and their supported counterparts was determined as the anion type. Accordingly, the basicity of the anion and the surface acidity of the metal oxide and their resulting interactions were found to have a significant effect on the thermal stability limits. Data presented here offer the opportunity to pick a suitable anion and cation pair according to the metal oxide, so that the supported IL can withstand the desired operation conditions in various applications, such as catalysis or gas separation

Priyadarshini, Antara published the artcileNanofiltration of Aqueous Dye Solution through the Diffused Rough Pores of a Carbonaceous-Kaolinite Amalgamation Membrane, SDS of cas: 79917-90-1, the publication is ACS ES&T Water (2022), 2(3), 414-424, database is CAplus.

This study demonstrates a supported carbonaceous-kaolinite composite membrane that has a highly porous medium with prevalent submicron pores. These pores exhibit a diffused configuration assembled by carbonaceous (Cn) nodules and kaolin particles wrapped by a thin Cn sheath. The membrane was prepared by three steps: (i) applying an acrylic-kaolin coating to a porous stainless-steel tube; (ii) compressing the dried coated layer in an isopress chamber to ratchet the amalgamated coating layer; and (iii) conducting partial pyrolysis to achieve the Cn-kaolin membrane (CKM), exhibiting a rough and diffused CK amalgam frame inherited from the intense compression. The membrane displays attractive nanofiltration performance, i.e., >95% rejection over 30 h and mean permeances of 4-10 L/h·m²·bar for the four probe dyes in water (50 ppm) with different mol. masses and charge types. The intricate and rough pore channels of the membrane agitate tiny turbulences amid the thin permeate streams, which drives an effective solute interaction with the pore walls. Solute retention occurred through entrapment along the pore walls, leading to a boundary layer, which assists further retention via dragging, circulating solute mols., and transferring them to the retentate. The filtrate permeates through nanopores of the CK amalgam frame.

Knowledge of the interaction parameters for polymers in different solvents is crucial for exploring the viscoelastic properties and processing capabilities of polymer solutions Here, we apply a scaling theory of semidilute polymer solutions to quantify the solution properties of cellulose, poly(ethylene oxide), poly(Me methacrylate), and poly(acrylonitrile-co-itaconic acid) in different ionic liquids The starting point of our approach is a scaling relationship between the solution correlation length ξ = lg^ν/B and the number of repeat units g in a correlation blob for polymers with a repeat unit projection length l, chain segment fractal dimension 1/ν, and the corresponding interaction parameter B describing polymer-solvent affinity and assuming values B_g, B_th, and 1 in different solution regimes. In the framework of this approach, we obtain crossover concentrations to the semidilute solution regime, c*, the solution regime of overlapping thermal blobs, c_th, and the concentrated solution regime, c**. The method takes advantage of the linear relationship of the specific viscosity η_sp with the number of correlation blobs per chain N_w/g in the unentangled Rouse regime for polymers with a weight-average d.p. N_w. The application of our approach to entangled solutions provides the chain packing number, P_e, and completes the set of parameters {B_g, B_th, and P_e} that uniquely describes the static and dynamic solution properties for a given polymer/solvent pair. This approach also allows us to identify a trend relating the B_g parameter to the van der Waals volume of the ionic liquid anion, analogous to the Hofmeister series, and to obtain the temperature and solvent type dependence of the polymer excluded volume and Kuhn length.

Tailoring various architectures of electrode material has been deemed a feasible route for improving the surface reactivity, the contact area between electrode and electrolyte, and enabling shortened electronic pathways to realize higher performance lithium-ion batteries. Here, we rapidly synthesized the manganese fluoride (MnF₂) with various morphologies by microwave irradiation using ionic liquid as the fluoride source, soft template, and microwave absorber solvent. The hierarchical nanostructured MnF₂ were optimized by controlling the purity of ionic liquid, microwave heating rate, and precursor concentration The dominant factors influencing the morphologies of MnF₂ were systematically investigated and relevant descriptions for the formation mechanism were suggested. Also, we demonstrated the abnormal high-capacity lithium-ion battery anode using the hierarchical nanostructured MnF₂ anode based on the conversion mechanism. The prepared MnF₂ anode yielded a maximum reversible specific capacity of 986 mAhg^-1 at 0.1C after 30 cycles. This study provides a comprehensive understanding of the morphol. control of the hierarchical structured MnF₂ using the microwave-ionic liquid combination method for high-capacity lithium-ion battery anode.
