Innovative materials of this era for toughening the epoxy matrix: A review

This review aims to bring to light the potential efficiency of various materials as toughening agents for epoxy thermosets. The area of epoxy toughening has fascinated material scientists since toughened epoxies are employed as the appropriate candidates in a wide arena of applications. Based on the structure?property relationships, the traditional chemistry approaches have been tried so far to toughen the epoxy matrix. With the advent of the era of nanotechnology, the field of epoxy toughening has also gained momentum through the utilization of various types of modified and unmodified nanofillers in the epoxy matrix. In fact many new materials have replaced the conventional agents in the field of epoxy toughening. We are giving a comprehensive review which hints the various mechanisms of toughening as well as the novel materials used in the present scenario as potential toughening agents in the epoxy matrix with special reference to rubber, block copolymers, and nanofillers.

An approach for the surface functionalized gold nanoparticles with pH-responsive polymer by combination of RAFT and click chemistry

In this report, we demonstrated a novel efficient post-modification route for preparation of smart hybrid gold nanoparticles with poly(4-vinylpyridine) (P4VP) based on RAFT and click chemistry. A new azide terminated ligand was first synthesized to modify gold nanoparticles by ligand exchange reaction, and then click reaction was used to graft alkyne terminated P4VP which was prepared by RAFT onto the surface of gold nanoparticles. The functionalized hybrid gold nanoparticles were characterized by TEM, FTIR, and XPS etc. The results indicated that the P4VP was successfully grafted onto the surface of gold nanoparticles by click reaction. The surface grafting density was calculated to be about 6 chains/nm2. In addition, the hybrid gold nanoparticles showed a pH responsive phenomenon as the pH value changed around 5. Crown Copyright

A structural and spectroscopic overview of molecular lanthanide complexes with fluorinated O-donor ligands

The lanthanide elements are prevalent in modern electronics, contrast agents, and phosphors. Precursors for luminescent materials frequently use fluorinated ligands to promote volatility for chemical vapor deposition methods. In molecular complexes, fluorination is also a commonly used technique to reduce energy loss during luminescence, and the oxophilicity of the lanthanide ions makes fluorinated alkoxides an attractive tool for the design of luminescent lanthanide complexes. Herein, the structural and photophysical properties of lanthanide complexes ligated by fluorinated alkoxides have been reviewed. Selected examples of several categories are presented in detail, including carboxylates, chelating and non-chelating ligands, and systems with up to three metal centers. Potential areas for further investigation are highlighted.

Coordination polymer networks with s-block metal ions

Alkali and alkaline earth metal cations form the s-block elements of the periodic table where they belong to the groups 1 and 2, respectively. They play an important role in nature, for instance alkali cations Li+, Na+ and K+ have very specific functions such as the regulation of the ionic equilibrium of living cells in our body. Alkaline earth cations also have a contribution in our body, for instance calcium is the most important constituent of our organism. They above all, and always, find applications in man-made materials in a wide range of fields: catalysts, ferroelectrics, metallic conductors and superconductor materials. They are known for their mainly ionic chemistry in aqueous medium, and a varying coordination number, depending on the size of the binding partners as well as on electrostatic interactions between the ligands and the metal ions. This makes the strategic synthesis of coordination polymer networks with these metal ions a challenge and explains why few systematic results in the generation of metal-organic frameworks (MOFs) are found in the literature. This review highlights the recent results in the field, bringing together the systematic approaches with results obtained by serendipity, to give an overview on current and future possibilities.

Fabrication of a molecularly imprinted polymer immobilized membrane with nanopores and its application in determination of beta2-agonists in pork samples

In this paper, a method for the synthesis of ractopamine molecularly imprinted polymers (MIPs) nanotube membranes on anodic alumina oxide (AAO) nanopore surface by atom transfer radical polymerization (ATRP) was presented, in which methacrylic acid (MAA) was selected as functional monomer with a polymerization rate of 1:6 between ractopamine and MAA by the computational investigations. The morphology of MIPs nanotube membranes characterized by scanning electron microscope (SEM) suggested a well growth in the AAO nanopore surface. A series of adsorption experiments revealed that the MIPs nanotube membranes showed better extraction capacity and good selectivity for ractopamine and its analogues than that of non-imprinted polymers (NIPs) nanotube membranes. In order to evaluate the usability of the MIPs nanotube membranes, a methodology by combining MIPs nanotube membranes extraction couple with high performance liquid chromatography (HPLC) detection for the determination of beta2-agonists in complex samples was developed. The linear ranges were 10-1000mug/L for ractopamine, 100-1000mug/L for clenbuterol, epinephrine and dopamine, and 200-1000mug/L for terbutaline. The detection limits were within the range of 0.074-0.25mug/L and the RSDs (n=3) were from 2.8% to 4.3%. The method was successfully applied to the analysis of beta2-agonists in spiked real samples, The recoveries of all the beta2-agonists at the two concentration levels were found to be within the range of 86.3-97.0% and 82.8-95.7%, respectively. The RSDs were within 2.7-5.7%. The results demonstrated that the proposed method is very suitable for the determination of beta2-agonists in pork samples.

Stereochemistry of solvation of benzylic lithium compounds: Structure and dynamic behavior

Several sec-benzylic lithium compounds, both externally coordinated, [alpha-(trimethylsilyl)benzyl]-lithium¡¤PMDTA (12) and p-tert-butyl-alpha-(dimethylethylsilyl)benzyllithium¡¤TMEDA (13), and internally coordinated, [alpha-[[[cis-2,5-bis(methoxymethyl)-1-pyrrolidinyl]methyl]dimethylsilyl]-p- tert-butylbenzyl]lithium (14) and [alpha-[[[(S)-2-(methoxymethyl)-1-pyrrolidinyl]methyl]dimethylsilyl]benzyl] lithium (15), have been prepared. Ring 13C NMR shifts indicate that 12-15 have partially delocalized structures. Externally solvated allylic lithium compounds are found to be delocalized, and only some internally coordinated species are partially delocalized. Compound 15 exists as > 95% of one stereoisomer of the two invertomers at Calpha. This is in accord with a published ee of > 98% in products of the reactions of 15 with aldehydes. All four compounds show evidence of one-bond 13C-6Li spin coupling, ca. 3 Hz, which indicates a small detectable C-Li covalence. Averaging of the 13C-6Li coupling of 12 with increasing temperature provides the dynamics of intermolecular C-Li bond exchange, with DeltaH?ex = 9 ¡À 0.5 kcal mol-1. Carbon-13 NMR line shape changes due to geminal methyls, and ligand carbons gave similar rates of inversion at Calpha in 13 (externally solvated) and 14 (internally solvated), DeltaH?inv ? 4.9 ¡À 0.5 kcal mol-1. By contrast, barriers to rotation around the ring-Calpha bonds vary widely, depending on the mode of lithium coordination, DeltaH?rot ? 8 ¡À 0.5 to 19 ¡À 1.0 kcal mol-1. Some mechanisms for these processes are proposed.

General procedure: A general method was used to synthesize the copper(II) complexes 1-5: To a pre-heated equimolar amounts of Cu(ClO4)2¡¤6H2O (0.190g, 0.50mmol) and the amine ligand (pmedien or DPA, 0.50mmol) dissolved in H2O (15mL), an aqueous solution of the sodium salt of the polycarboxylate compound (0.25mmol) was added. The resulting intense blue solution was heated on a steam-bath for 15min, filtered through Celite and then allowed to crystallize at room temperature. The crystalline solid which separated over a period of 4-12days was collected by filtration, washed with propan-2-ol, ether and allowed to dry in air. Single crystals suitable for X-ray structure analysis were obtained from dilute solutions by crystallization from H2O.
