Crystallization-Driven Self-Assembly of a Block Copolymer with Amphiphilic Pendant Groups

Crystalline-coil block copolymers (BCPs) with an amphiphilic corona-forming block broaden the range of solvents in which crystallization-driven self-assembly experiments can be carried out. These materials allow one to examine how rather large changes in solvent polarity can affect the self-assembly process, leading to novel uniform structures. Here, we describe the synthesis and self-assembly properties of a crystalline-brush BCP, PFS27-b-P(EG-E) MA(48) (PFS, poly(ferrocenyldimethylsilane), and P(EG-E)MA, poly(tetraethylene glycol monododecyl ether methacrylate); the subscripts refer to the mean degrees of polymerization). Tetrahydrofuran (THF) is a common good solvent for both blocks, whereas the corona polymer itself is soluble in alcohols ranging from 2-propanol to 1-decanol and in octane and decane. Self-assembly in 2-propanol was normal, forming long (>5 mu m) fiber-like micelles of uniform width when the polymer suspended in solvent was heated (i.e., 80 degrees C) and cooled. Micelles of similar width but uniform and variable length were obtained when micelle fragments were subjected to seeded growth or self-seeding conditions. In primary alcohols (1-butanol to 1-decanol), direct self-assembly led to uniform scarf-like structures (total length similar to 2 mu m) in which the length of the central platelet increased with the carbon number in the solvent, offset by shorter fiber-like protrusions at the ends. We speculate that these changes are related to the temperature at which core crystallization occurred as the samples cooled. Selfassembly in decane was more complicated. Large (>10 mu m) aggregated structures consisting of fiber bundles formed initially. Sonication followed by seeded growth with additional BCP or self-seeding led to relatively uniform elongated lenticular micelles, substantially wider than those formed under these protocols for this BCP in 2-propanol. Solvent polarity has a profound effect on the self-assembly of this BCP with a brush-like amphiphilic corona-forming block.

Application of Monopotassium Dipropylene Glycoxide for Homopolymerization and Copolymerization of Monosubstituted Oxiranes: Characterization of Synthesized Macrodiols by MALDI-TOF Mass Spectrometry

Monopotassium dipropylene glycoxide, activated by a 18-crown-6 cation complexing agent (K-DPG/L, where DPG (dipropylene glycol) is a mixture of isomers) was used as an effective initiator of the homopolymerization and copolymerization of several monosubstituted oxiranes, i.e., propylene oxide (PO), 1.2-butylene oxide (BO), and some glycidyl ethers such as allyl, isopropyl, phenyl, and benzyl ones (AGE, IPGE, PGE, and BGE, respectively). The copolymers are novel and can be prospectively used for the fabrication of new thermoplastic or crosslinked polyurethanes. All processes were carried out in homogeneous mild conditions, i.e., tetrahydrofuran solution at room temperature and normal pressure. They resulted in new unimodal macrodiols with M-n = M-calc in the range of 1500-8300, low dispersity M-w/M-n = 1.08-1.18 and a chemical structure well defined by several techniques, i.e., MALDI-TOF, size exclusion chromatography (SEC), C-13 NMR, and FTIR. Monopotassium salts of homopolyether-diols, i.e., PPO-diol, PBO-diol, and PAGE-diol, appeared to be useful macroinitiators for the preparation of new triblock copolyether-diols by polymerization of glycidyl ethers. In BO/BGE random copolymerization initiated with K-DPG/L, macromolecules of copolyether-diol were exclusively formed. Macromolecules of copolyether-diol accompanied by homopolyether PPO-diol were identified in the PO/PGE system. However, AGE and PGE reacted by giving random copolyether-diol as well as homopolymer-diols, i.e., PAGE-diol and PPGE-diol. Macromolecules of prepared copolyether-diols contain various numbers of mers deriving from comonomers; the kind of comonomer determines the composition of the product. Several prepared homopolyether-diols and copolyether-diols could be useful for the synthesis of new thermoplastic polyurethanes.

The controllable nanostructure and photocatalytic behaviour of 5,10,15,20-tetra-(3,4,5 trimethoxyphenyl)porphyrin through solvophobic supramolecular self-assembly

In this study, the self-assembly of 5,10,15,20-tetra(3,4,5-trimethoxyphenyl)porphyrin (coded as: TTOP) in a mixture of tetrahydrofuran (THF) and H2O and the photocatalytic activity of the resulting self-assembled aggregates toward the degradation of organic compounds were investigated. TTOP was well dispersed as monomers in THF, however, it stacked into aggregates upon the addition of water (20-90%). Depending on the THF/H2O mixture various nanostructures were observed. Microrods with an average width of 0.62 +/- 0.22 mu m and length of 10.17 +/- 2.04 mu m and sphere-like particles with diameters ranging from 0.5 to 1.2 mu m were obtained in 70% water in THF. Nonetheless, the particles disappeared and the rods turned to slabs with the same length but much larger width (4.48 +/- 2.27 mu m) when 80% water in THF was used. Particles with irregular shapes, which connected into large aggregates, were obtained at 90% water in THF. These structures exhibited a significant difference in photocatalytic ability for the degradation of dye (rohdamine B, RhB and methylene blue, MB). The rate constants of RhB degradation were 4.35 x 10(-4) min(-1), 1.13 x 10(-3) min(-1), 2.63 x 10(-3) min(-1), and 3.52 x 10(-3) min(-1) for the porphyrin monomer in THF and its aggregate states obtained by mixing 70%, 80%, and 90% water in THF, respectively. These results indicated the important role of solvent in the formation and control of the structures of porphyrin aggregates, which are crucial to an effective porphyrin-based photocatalyst.

Composition dependence on the spectral behavior of magnesium aluminum chloride complex electrolytes

A composition-dependent study is presented for 1:1 and 2:1 MgCl2:AlO3 (MACC)-tetrahydrofuran (THF) electrolytes and the findings very well support electrochemical data reported in the literature. Quantitative Raman analyses in the region characteristic of the nu(cc) and nu(co) modes of THF at around 915 cm(-1) were performed and correlated with the low wavenumber region. The nu(Al-O) and nu(Mg-O) vibrations are reported for the first time and are in excellent agreement with the solvates identified in the IR and Raman spectra. Although AlCl3.xTHF (x = 1-2) are present in these solutions, the systems are governed by the [AlCl4](-) anion. In light of our spectroscopic results, [Mg(THF)(6)](2+) is the major species and responsible for the lower electrochemical performance of the 1:1 electrolyte, whereas [MgCl2(THF)(4)] and [(mu-Cl)(3)Mg-2(THF)(6)](+) are the complexes related with the higher electrochemical activity of the 2:1 proportion.

Electrolyte design for Li metal-free Li batteries

Li metal, with the lowest thermodynamically achievable negative electrochemical potential and the highest specific capacity (3860 mAh g(-1)), is the ultimate anode choice for Li batteries. However, the highest reported Li plating/stripping Coulombic efficiency (CE) of 99.5% after extensive efforts is still too low for the Li metal-free (all the Li metal in cycling comes from cathode, without anode prelithiation) Li metal batteries. The low CE is attributed to both non-uniform Li plating/stripping on the lithiophobic Cu current collector and Li dendrite growth through lithiophilic organic-inorganic solid electrolyte interphase (SEI) formed in carbonate electrolytes. Here, we use a lithiophilic Bismuth graphite blend (Bi-Gr) substrate to replace lithiophobic Cu current collector to seed a uniform Li nucleation, and form a lithiophobic LiF-rich SEI rather than lithiophilic organic-rich SEI to suppress Li dendrite growth. Molecular dynamics simulations reveal the preferential reduction of anions in 2.0 M LiPF6 in tetrahydrofuran/2-methyl tetrahydrofuran (2.0 M LiPF6-mixTHF) electrolyte to generate LiF-rich SEI on plated Li. Bi-Gr substrate and 2.0 M LiPF6-mixTHF electrolyte enable the Li anodes to achieve a record high CE of 99.83% at a high capacity of 1.0 mAh cm(-2) and current of 0.5 mA cm(-2). The Bi particles serve as dispersed nucleation centers that promote uniform Li deposition with strong adhesion to the substrate to avoid dead Li, while the lithiophobic LiF-rich SEI promotes lateral Li growth and suppresses the vertical Li dendrite growth even at a high current density of 3.0 mA cm(-2) and high areal capacities of 3.0 mAh cm(-2). The regulation of Li nucleation and growth enables the Li metal-free LiFePO4 full cells to achieve 100 cycles at a practical areal capacity of >2.0 mAh cm(-2). This manuscript highlights the benefits of simultaneous substrate design to improve Li nucleation and electrolyte design to promote lithiophobic SEI growth, enabling a promising and practical route Li metal-free Li metal batteries.

Effect of the Organic Functionality on the Synthesis and Antimicrobial Activity of Silver Nanoparticles

In this paper, the effects of the organic reducing agent and 3-aminopropyltrimethoxysilane on the synthesis and properties of mono-, bi-, and trimetallic noble metal nanoparticles were considered; the antimicrobial activity of these nanomaterials was also evaluated. It was shown that 3-aminoptopyltrimethoxysilane-treated noble metal cations undergo rapid conversion into nanoparticles in the presence of three organic reducing agents, namely, 3-glycidoxypropyltrimethoxysilane (3-GPTMS), cyclohexanone and formaldehyde; the nanoparticles were formed on the order of one minute under microwave incubation. Bimetallic nanoparticles were formed by simultaneous or sequential reduction of metal cations; the formation of trimetallic nanoparticles containing gold, silver and palladium was demonstrated using a similar approach. The nanoparticles were characterized using UV-Visible light spectrophotometry, transmission electron microscopy and zeta potential measurements. All three nanoparticles exhibited a size <= 10nm size. The nanoparticles showed antimicrobial activity against Acinetobacter baumannii. Scanning electron microscopy imaging showed an alteration in the size and shape of nanoparticle-treated bacterium, with bleb formation and cell wall disruption observed within 1 h of incubation at the MBC values of the nanoparticles. Fluorescence spectrophotometric imaging of silver nanoparticle-Acinetobacter baumannii interactions suggested selective binding of silver nanoparticles to surface proteins. Our results showed the preparation of the novel silver nanoparticles with potent Anti-Acinetobacter baumannii activity, which can serve as an alternative to conventional antimicrobial agents.

SIMULTANEOUS ESTIMATION OF DAPSONE AND ADAPALENE IN GEL FORMULATION BY UV- SPECTROSCOPY

Objective: A new, simple, sensitive, and economical UV spectrophotometric method was developed for the simultaneous analysis of Adapalene and Dapsone in pharmaceutical formulation. Method: This UV method was developed with Tetrahydrofuran and Distilled water as solvents. The wavelengths selected for analysis in the present method were 237 nm and 293 nm. The method was validated as per ICH guidelines. Results: The method was validated for linearity, accuracy, precision, specificity and robustness. Linearity was found to be within the concentration range of 0.05-0.25 mu g/ml for Adapalene and 2.5-12.5 mu g/ml for Dapsone. Accuracy for the method was determined by recovery studies. The % drug recovered was found to be 99-102% w/w. The % RSD values of repeatability and intermediate precision were found to be less than 2, providing method was precise in nature. From all these studies it was observed that there was no interference of excipients from the formulation during the analysis. Conclusion: The advantages of this method for analytical purposes lie in the rapid determination, its cost-effectiveness, easy preparation of the sample and good reproducibility. In addition to this, the present method can be recommended for the simultaneous determination of Adapalene and Dapsone in routine quality control analysis in combined drug formulations.
