Preventing hydrates cohesion with a bio-inspired vitamin E derivative

A solidified natural gas (SNG) technology was investigated to transport natural gas in a hydrate slurry. A Vitamin E derivative (D-alpha tocopherol succinate, Vitamin E-TS), which is naturally derived and readily available, was used to disperse water in the decane phase under the turbulent mixing condition. Compared to other non-ionic or cationic surfactants, Vitamin E-TS induced fast hydrate formation and a high conversion rate with an advantage of maintaining flowability during hydrate formation. For example, when using sorbitan monostearate (Span-60), hydrates grew to form a thick layer at the decane/water interface. Due to the strong cohesion of hydrate in the layer, a high relative torque was observed on mixing and the impeller was stopped. Moreover, dodecyl-trimethylammonium bromide (DTAB) showed increased relative torque in the early stage of hydrate formation. From the experimental results under both steady and dynamic operating conditions, Vitamin E-TS showed the optimal performance in quickly producing hydrate slurries and high conversion while maintaining fluid flowability. Accordingly, a continuous process was proposed to use water and decane as feed to produce the hydrate slurry in the presence of Vitamin E-TS.

Influence of surfactant and molarity on the properties of bacterial cellulose/polyaniline: Experimental and density functional theory

In this work, the structure-property relationship was evaluated in the synthesis of bacterial cellulose (BC)/polyaniline (PANI) nanocomposite aerogels in terms of both experimental and density functional theory (DFT) simulation. The molarity of HC1 solution (0.01 and 0.5 M) and the presence/absence of cetyltrimethylammonium bromide (CTAB) were the main parameters of synthesis conditions. DFT simulation showed that the formation of hydrogen bonds governed interaction between BC and PANI, and PANI had more tendency to BC than that of CTAB at 0.5 M. It was confirmed by the formation of shorter hydrogen bonds between BC and pmtonated PANI at 0.5 M. Regarding this fact, prepared samples at 0.5 M of HCl solution and the presence of CTAB experienced higher storage modulus and electrical conductivity by 2000 Pa and 4 order of magnitude than those of lower molarity (0.01 M). These findings were in accordance with simulation outcomes.

Mono- and Tri-Functionalization of Trimethylresorcin[4]arenes

Short and efficient syntheses of mono- and tris-functionalized resorcin[4]arenes were developed. The co-condensation of resorcinol and 2-methylresorcinol was optimized, targeting for the trimethylresorcin[4]arene, easy to isolate. Complementary regiospecific conditions for the mono- and tris-halogenation in almost quantitative yields are setting the stage for subsequent functionalizations: radicalic bromination leads to the trisbromomethyl compound, while the polar bromination and iodination via the mono-lithiated species leads to the aryl bromide and iodide in excellent yields.

Role of Carbonate Species on General Acid Catalysis of Bromide Oxidation by Hypochlorous Acid (HOCl) and Oxidation by Molecular Chlorine (Cl-2)

Kinetic models for disinfectant decay and disinfection byproduct (DBP) formation are necessary for predicting water quality from the treatment plant to the tap. A kinetic model for conditions relevant to chloramine disinfection of drinking water (pH 6-9 and carbonate-buffered) was developed to simulate incomplete bromide (Br-) oxidation during short prechlorination periods because it is the first step in a complex system of reactions that leads to disinfectant loss and DBP formation. Hypochlorous acid (HOCl + Br- ->(kHOCl) HOBr + Cl-) and molecular chlorine (Cl-2 + Br- + H2O ->(KCl2) HOBr + 2Cl(-) + H+) were the free chlorine species relevant to Br- oxidation, and Cl-2 hydrolysis and formation reactions (Cl-2 + H2O + A(-) reversible arrow(k4)(k-4) HOCl + HA + Cl-) were necessary to accurately simulate Cl-2 concentrations instead of assuming equilibrium. Previous work has shown that Br- oxidation by HOCl and Cl-2 formation are acid-catalyzed and Cl-2 hydrolysis is base-catalyzed, but the impact of carbonate species had not been studied. This work showed that the carbonate species have an enhanced catalytic impact with rate constants up to 1000 times larger than would be estimated by the Bronsted relationship for similar acids, which causes the oxidation by HOCl rate constant (kHOCl) to nearly double and oxidation by Cl-2 to occur above pH 7 in high-alkalinity waters.

Wafer-Scale Diisopropylammonium Bromide Films for Low-Power Lateral Organic Ferroelectric Capacitors

Organic ferroelectrics, particularly the polymer polyvinylidene fluoride and its copolymer polyvinylidene fluoride-trifluoroethylene, have received much attention owing to their low cost, flexibility, and convenient thin film fabrication. However, development of this outstanding material for electronic applications is significantly impeded by its attributes of large coercive electric fields and poor spontaneous polarization. While the recent breakthroughs reveal that several kinds of molecular ferroelectrics (e.g., diisopropylammonium bromide (DIPAB)) can exhibit excellent properties comparable to inorganic ferroelectrics, it is still difficult to obtain high-quality continuous thin films for ferroelectric devices with high performance. In this work, a simple solution strategy is used for the preparation of large-area high crystallinity or even single-crystal DIPAB films. Subsequently, planar ferroelectric capacitors are developed with large in-plane ferroelectric polarization. These capacitors possess excellent memory function with small operating voltages (1-3 V), and a record remnant polarization of 13 mu C cm(-2) for organic ferroelectric devices. The findings have the potential to pave the way for the substitution of conventional ferroelectric polymers with DIPAB films for future organic ferroelectric devices.

Solid polymer electrolytes based on poly(vinyl alcohol) incorporated with sodium salt and ionic liquid for electrical double layer capacitor

Solid polymer electrolyte (SPE) based on poly(vinyl alcohol) (PVA) as a host polymer, sodium trifluoromethanesulfonate (NaTf) salt, and 1-butyl-3-methylimidazolium bromide (BmImBr) ionic liquid is fabricated using solution casting technique. The ionic conductivity, crystallinity, composition and thermal stability were characterized by electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), respectively. The optimum ratio between PVA and NaTf salt to obtain highest ionic conductivity was found to be as 60:40. The inclusion of BmImBr ionic liquid into the optimized PVA-based SPE significantly enhanced the ionic conductivity. XRD pattern indicated the successful dissolution of NaTf salt and complexation of BmImBr ionic liquid in the host polymer which has also been confirmed by FTIR spectra. The thermally stable SPE is suitable for electrical double layer capacitor (EDLC) application. The electrochemical studies of GPE for EDLC showed promising performance producing specific capacitance of 16.32 F g(-1).

Differential effect of surfactants tetra-n-butyl ammonium bromide and N-Cetyl-N, N, N-trimethyl ammonium bromide bound to nano-cellulose on binding and sustained release of some non-steroidal anti-inflammatory drugs

Nano crystalline cellulose (NCC) modified with cationic surfactant CTAB (N-Cetyl-N, N, N-trimethyl ammonium bromide) proved as effective drug delivery excipient for sustained release of non-steroidal anti-inflammatory drugs (NSAIDs). In the present work, our purpose was to study the effect of another cationic surfactant TBAB (tetra-n-butyl ammonium bromide) used to modify NCC on binding and sustained release of hydrophobic NSAIDs. NCC modified TBAB was characterized by FTIR & TGA analysis. TBAB-NSAID interactions have been assessed using CHEM3D. The sustained release character was monitored by time dependent serum protein protecting and time dependent anti-cathepsins activities. The NCC-TBAB exhibited the binding efficiency for NSAIDs in the range of 42-25% depending upon the hydrophobicity of NSAID and released the drug up to 60 min. The research problem added to the existing knowledge of suitable surfactants required to change the hydrophilic nature of NCC to act as carrier for hydrophobic drugs. TBAB surfactant having shorter alkyl chain length exhibited lower binding efficiency and decreased sustain release of drugs as compared to CTAB having longer alkyl chain length.

Highly Regioselective 5-endo-tet Cyclization of 3,4-Epoxy Amines into 3-Hydroxypyrrolidines Catalyzed by La(OTf)(3)

Highly regioselective intramolecular aminolysis of 3,4-epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)(3) catalyst and (2) excellent regioselectivity for anti-Baldwin 5-endo-tet cyclization. This reaction affords 3-hydroxy-2-alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed that the regioselectivity might be attributed to distortion energies of epoxy amine substrates. The use of this reaction was demonstrated by the first enantioselective synthesis of an antispasmodic agent prifinium bromide.
