Application of a quantum cascade laser aperture scanning near-field optical microscope to the study of a cancer cell

This work reports the first images obtained by combining an infrared aperture scanning near-field optical microscope (SNOM) with a quantum cascade laser (QCL). The future potential of this set-up is demonstrated by a preliminary study on an OE33 human oesophageal adenocarcinoma cell in which the cell is imaged at 1751 cm(-1), 1651 cm(-1), 1539 cm(-1) and 1242 cm(-1). In addition to the 1651 cm(-1) image, three other images were acquired within the Amide I band (1689 cm(-1), 1675 cm(-1) and 1626 cm(-1)) chosen to correspond to secondary structures of proteins. The four images obtained within the Amide I band show distinct differences demonstrating the potential of this approach to reveal subtle changes in the chemical composition of a cell.

Nicotinamide Promotes Cell Survival and Differentiation as Kinase Inhibitor in Human Pluripotent Stem Cells

Nicotinamide, the amide form of vitamin B3, is widely used in disease treatments and stem cell applications. However, nicotinamide’s impact often cannot be attributed to its nutritional functions. In a vitamin screen, we find that nicotinamide promotes cell survival and differentiation in human pluripotent stem cells. Nicotinamide inhibits the phosphorylation of myosin light chain, suppresses actomyosin contraction, and leads to improved cell survival after individualization. Further analysis demonstrates that nicotinamide is an inhibitor of multiple kinases, including ROCK and casein kinase 1. We demonstrate that nicotinamide affects human embryonic stem cell pluripotency and differentiation as a selective kinase inhibitor. The findings in this report may help researchers design better strategies to develop nicotinamide-related stem cell applications and disease treatments.

Nano-dispersion of organo-modified nanofiller in partially fluorinated matrix as the polymer/magnetic nanoparticle composites

A transparent and flexible crystalline polymer nanohybrid was fabricated, containing well-dispersed magnetic nanoparticles (MNPs) with organic chain-modified surfaces. The partially fluorinated copolymer matrix used is composed of switchboard-type lamellae. These become transparent owing to the creation of high-density amorphous regions on drawing the corresponding film at just below the polymer melting point. Although the creation of oleo- and hydrophobic fluorinated polymer/organo-modified MNP nanohybrids is generally difficult, formation via melt compounding was confirmed using wide-angle X-ray diffraction and thermal analysis. On organo-modification of the hydroxyl-terminated MNP surface with long-chain fatty acids, the resulting improvement in wettability aids the dispersion of the particles and hence maintains transparency. Nano-dispersion of the organo-filler was considered to result from surface modification-induced improvement of particle miscibility and melt compounding. These nanohybrids have enhanced thermal degradation temperatures and mechanical properties, derived from the nucleation effect caused by the adsorption of the terminal polymer chains onto the organic modifier.

Study on the evolution characteristic of intermediate during the pyrolysis of oil shale

The pyrolysis of oil shale is a complex process including a myriad of chemical reactions. A widely approved understanding suggests a two-step decomposition process for oil shale pyrolysis, considering bitumen as the intermediate product. In this study, intermediates derived from various pyrolysis conditions are comprehensively studied by FTIR, GC, GC-MS and NMR methods to understand the pyrolysis mechanism of oil shale and composition feature of intermediate. The pyrolysis of oil shale is a dynamic process, and the results show that the intermediate is continuously generated before 400 A degrees C, accompanying with the formation of final products from both intermediate and kerogen. The maximum yield of intermediates is presented at the fastest oil-producing temperature range (375 A degrees C in this study). Carbon chains in intermediate become short with the increase in temperature. Most components in pyrolysis intermediate are long straight aliphatic chains; thus, intermediate is much heavier than shale oil. Further reactions make intermediate convert into shale oil product. Aliphatic hydrocarbons occupied the biggest proportion over 86% at 375 A degrees C, mainly in the form of straight-chain alkanes. A few parts of aromatic fragments with small ring numbers will also transfer into intermediate. The heteroatom-containing compounds are mainly alcohols, ketones, amides and halohydrocarbons. High aromaticity in shale oil at high temperatures can be attributed to the condensation reaction of abundant aliphatic hydrocarbons in intermediate. During the conversion process from intermediate to final products, the generating capacity of oil is evidently higher than that of gas.

Autofluorescent Hyperbranched Poly(amide amine) as Effective Fluorescent Probe for Label-free Detection of Copper(II) Ions

A label-free fluorescent probe based on autofluorescent hyperbranched poly(amide amine) (HPAMAM) for copper ions was designed. HPAMAM is a cationic polymer containing many amino groups, which could bind Cu2+ ions to form cupric amine complexes, leading to a selective quenching of the fluorescence intensity of HPAMAM via inner filter effect. The fluorescence intensity of HPAMAM decreased with increasing concentration of Cu2+ ions and the linear response ranged from 0.05 to 25 mu M (R-2 = 0.995), with the corresponding detection limit (3 sigma /k) of 17.15 nM. The HPAMAM fluorescent probe provided a simple, rapid, selective and sensitive fluorometric method for detecting Cu2+ ions, which could be also applied for detection of Cu2+ ions in real water samples.

Synthesis of homoleptic, divalent lanthanide (Sm, Eu) complexes via oxidative transmetallation

The direct synthesis of neutral, divalent samarium and europium complexes supported by the bulky bis(tris-tert-butoxysilyl)amide (BTTSA) ligand via oxidative transmetallation is reported. Through the use of a copper(i) ligand complex, conventional lanthanide halide starting materials for complex formation are circumvented and the clean formation of divalent complexes is achieved directly from the bulk metal. The structures of the [Ln(BTTSA)(2)] (Ln = Sm, Eu) complexes are isotypic, presenting divalent lanthanide ions with distorted, six-coordinate geometries.

Ru-Catalysed synthesis of fused heterocycle-pyridinones and -pyrones

The synthesis of fused heterocycle-pyridinones has been achieved by oxidative coupling of N-unprotected primary heterocycle-amides with internal alkynes. The reaction, which is catalysed by Ru(II) and assisted by Cu(II), takes place through C-H and N-H bond activation of the heterocyclic unit. The scope of the reaction includes a variety of alkynes, electron-rich thiophenes, furans and pyrroles, and even electron-poor pyridines. The reaction is fully regioselective with respect to the position of the C-H bond activation due to the directing effect of the amide group. In the same way, the synthesis of fused heterocycle-pyrones (isocoumarins) has been developed by Ru-catalysed oxidative coupling of heterocyclic carboxylic acids and internal alkynes. The reaction involves C-H and O-H bond activation. This reaction also has a broad scope, from electron-rich thiophenes, furans and pyrroles to electron-deficient pyridines and quinolines.

Reusable Fe2O3-nanoparticle catalysed efficient and selective hydroboration of carbonyl compounds

The first Fe2O3-nanoparticle catalysed hydroboration of aromatic and aliphatic aldehydes and ketones with HBpin (pin = OCMe2CMe2O) is reported. The reaction proceeds under mild conditions (room temperature) and is moderately sensitive to air. This process is applicable to a broad range of substrates with high functional group compatibility. Moreover, aldehydes are selectively hydroborated over other reducible functional groups, such as ketone, nitrile, hydroxide, alkene, amide, ester, nitro and halide groups.

Preparation and characterization of ultra-thin poly ether block amide/nanoclay nanocomposite membrane for gas separation

Supported Mixed Matrix Membrane (SMMM) Polyether block amide/nanoclay (PEBA/Cloisite 30b), based on Polyacrylonitrile on nonwoven Polyester (PAN/PE), was fabricated by the spin coating method, following optimization of fabrication conditions for Single-Layer Mixed Matrix Membranes (SLMMMs). Cloisite 30b is a type of montmorillonite modified from nanoclays family. The fabricated membranes were examined structurally through The X-ray Diffraction (XRD), The Field Emission Scanning Electron Microscopy (FESEM), The Fouriertransform infrared spectroscopy (FTIR), and The Atomic force microscopy (AFM) analyses, and evaluated operationally by conducting permeability tests of the pure gases of CO2, CH4 and N-2. The effect of different Cloisite 30b loadings and the varying pressures on the gas separation performance of the membranes was investigated. Elevation of the loading up to 0.2 wt% Cloisite 30b increased the permeability and the selectivity, whereas further increase up to 1 wt% reduced the permeability and selectivity. After an increase in pressure from 4 to 14 bar, an elevated permeability and selectivity was observed. The membrane with a Cloisite 30b loading of 0.2 wt% had the best performance in the separation of the pure gases of CO2, CH4, and N-2 such that the permeability of CO2 , along with the selectivity of CO2/N-2, and CO2/CH4 had increase of about 55.55%, 26.45% and 38% in comparison with the Single Layer Neat Membrane (SLNM). The permeability of CO2, the selectivity of CO2/N-2, and the selectivity of CO2/CH4 of SMMM with a Cloisite 30b loading of 0.2 wt% also indicated an increase of about 364%, 18% and 47.8% in comparison to the Supported Neat Membrane (SNM). Furthermore, CO2 permeability through SMMM with cloisite30b loading of 0.2 wt% indicated a growth of about 562.5% in comparison to SLMMM with the same loading.
