Determination of lipoic acid in human plasma by high-performance liquid chromatography with ultraviolet detection

This paper describes the development and validation of an HPLC method for the determination of protein bound and total lipoic acid in human plasma. The essential steps in the total lipoic acid assay include reduction of disulfide bridge with tris(2-carboxyethyl)phosphine, derivatization via thiol group with 1-benzyl-2-chloropyridinium bromide and HPLC analysis of S-pyridinium derivative. Protein-bound lipoic acid is first separated from free lipoic acid with the use of liquid extraction, converted to its reduced counterpart then processed as total lipoic acid. The method is reproducible, precise and accurate. The inter- and intraday related standard deviation varied from 1.5% to 11.5% and from 1.8% to 19.6%, respectively, while recovery is in the range of 80.0-106.0% and 80.4-110.8%, respectively. The mean concentration of total lipoic acid in healthy donors after supplementation with 600 mg and 1200 mg was 0.67 +/- 0.40 mu mol L-1 (137.6 +/- 82.1 mu g L-1) and 1.57 +/- 0.34 mu mol L-1 (323.34 +/- 70.07 mu g L-1), respectively.

Preparation of Chitosan and Glycol Chitosan Coated Magnetic Nanoparticles Loaded with Carboplatin as Anticancer Drug

Surface modified Fe3O4 nanoparticles ( Fe3O4-OA) with an average diameter of 10 nm were synthesized, coated by chitosan (CS) and glycol chitosan (GCS), thus magnetic polymer nanocomposites were obtained. The magnetic nanostructures were analyzed by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and vibrating sample magnetometer (VSM). All magnetic structures synthesized in this study exhibited superparamagnetic properties. Loading carboplatin (CPt) as anticancer drug to Fe3O4-OA-GCS nanocomposites were carried out with 13.17 % drug content and 38 % encapsulation efficiency. The cytotoxicity studies were occured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay on L929 mouse fibroblasts and MCF-7 human breast cancer cells. Fe3O4-OA-GCS-CPt nanocomposites showed higher cytotoxicity than free CPt on the MCF-7 cells at 50 mu g/ml drug concentrations during 72 h.

Probe Molecules for Pulsed-Field-Gradient Diffusion Nuclear Magnetic Resonance Experiments on Micelles

Nuclear magnetic resonance (NMR) diffusion measurements of surfactants suffer from fast exchange of the surfactant between the micellar aggregate and bulk solution. Therefore, hydrophobic probe molecules are commonly used to directly measure aggregate diffusion under the assumption that the probe molecules remain solubilized inside the micelles. Aggregate size is then determined or estimated from the aggregate diffusion value. Unfortunately, the probe molecule also experiences rapid exchange between the aggregate and bulk, leading to inaccurate or unreasonable micelle diffusion values, a fact that has often been ignored in the literature. In this article, we present a systematic evaluation of probe molecules in cationic and anionic surfactants, obtained by measuring the diffusion of probe molecules with varying hydrophobicity. We find that an octanol-water partition coefficient of at least similar to 5 is required for correct measurements of aggregate diffusion in the systems studied. Notably, some commonly used probes have a partition coefficient much lower than five and are therefore not suitable for aggregate diffusion measurements. Consideration of these results will help researchers obtain accurate results for micelle sizing or partitioning studies with pulsed-field-gradient NMR.

Characterization of Substituted 1,3-Dioxolanes and 1,3-Dioxanes by Gas Chromatography-Mass Spectrometry

Until recently, one of the reasons for the unsatisfactory characterization of alicyclic ketals of aliphatic and alkylaromatic ketones was the absence of any mention of the presence of such compounds in natural samples. Another reason is in the low yields of such ketals on the interaction of ketones and diols under the conditions of conventional acid catalysis. To optimize the synthesis of trace amounts of such ketals, we used cobalt(II) bromide and dimethyl glyoxime as catalysts. The simplest chromatographic parameters, including the difference between the retention indices of the products and the starting compounds (difference in retention indices, DRI), are effective for identifying the target ketals in reaction mixtures. Such combined chromatography-mass spectrometric characteristics as homologous increments of retention indices (i(RI)) are informative not only for the group identification of analytes (assignment to the corresponding homologous series) and the assessment of their molecular weights (at low-intense signals of molecular ions). They are also useful for the determination of the total number of branches of the sp(3)-carbon skeleton of molecules (N) using the regression of N approximate to ai(RI) + b.

Facile assembly of mesoporous silica nanoparticles with hierarchical pore structure for CO2 capture

In the work, we propose an efficient one-pot approach for synthesis of a new type of mesoporous silica nanoparticles (MSNs). That can be successfully realized by using tetraethylorthosilicate (TEOS) and N-[3-(trimethoxysilyl)propyl]ethylenediamine (TSD) as the silica precursors and cetyltrimethylammonium bromide (GAB) as the structure-directing agent through a facile assembly process. The as-synthesized MSNs possess a spherical morphology with about 230 nm, a relatively high surface area of 133 m(2)/g, and a hierarchical pore size distribution. When applied as the sorbents, the amine-functioned MSNs demonstrate the enhanced adsorption capacity for CO2 capture (at 1 bar, 15 vol% CO2, up to 80.5 mg/g at 75 degrees C), high selectivity, and good cycling durability, benefiting from the suitable modification of polyethyleneimine.

Advanced Modification of Perovskite Surfaces for Defect Passivation and Efficient Charge Extraction in Air-Stable CsPbBr3 Perovskite Solar Cells

An all-inorganic cesium lead bromide (CsPbBr3) halide has attracted growing attention for carbon-based perovskite solar cells (PSCs) owing to its inherent stable lattice in thermal and/or moisture ambient. The main drawback for carbon-based CsPbBr3 PSCs is the low power conversion efficiency (PCE) caused by serious charge recombination at perovskite surfaces and/or device interfaces. To address this problem, an interface engineering strategy by modifying a polyvinyl acetate (PVAc) polymer with a carbonyl group at the interface of CsPbBr3/carbon is implemented to passivate perovskite surface defect states and also to improve energy-level alignment between the valence band of CsPbBr3 and work function of carbon, suppressing charge recombination and accelerating charge separation. By introducing the graphene oxide (GO) layer for further promoting hole extraction and decreasing energy-level difference, the PSC with an architecture of FTO/c-TiO2/m-TiO2/CsPbBr3 /PVAc/GO/carbon achieves a champion PCE as high as 9.53%, yielding an improvement by 44.0% compared with 6.62% for the original device. Furthermore, the optimal device free of encapsulation exhibits remarkable long-term stability under high humidity, high temperature, and continuous illumination in air. This work provides a new polymer as the interface modification material for reducing defect states as well as enhancing energy-level alignment and suggests an effective approach for fabricating efficient and stable carbon-based CsPbBr3 PSCs.

On-Surface Intramolecular Dehalogenation of Vicinal Dibromides for the Direct Formation of C-C Double Bonds

The intramolecular dehalogenation reaction as an essential step is generally involved in the deprotection of carbon-carbon double bonds in solution chemistry. However, harsh reaction conditions often limit the functional group compatibility and cause the selectivity problems. In comparison with traditional solution reactions, on-surface chemical reactions always occur on metal substrates, which could serve as catalysts to effectively reduce the reaction barriers in many cases. On the other hand, on-surface intermolecular dehalogenative homocoupling reactions have been extensively demonstrated, while, to our knowledge, intramolecular dehalogenation reactions are less discussed on surfaces. Herein, by the combination of high-resolution scanning tunneling microscopy imaging and density functional theory calculations, we introduce the vicinal dibromo group on chemically different surfaces, such as Cu(110), Ag(110), and Au(111), respectively, to investigate the generality of intramolecular dehalogenation reactions. As a result, we successfully achieved the direct formation of C-C double-bonded products in a facile manner on all three surfaces.
