Synthesis and properties of greenish-blue-emitting iridium dendrimers with N-phenylcarbazole-based polyether dendrons by a post-dendronization route

26-11-2014 | Yang Wang; Shumeng Wang; Shiyang Shao; Junqiao Ding; Lixiang Wang; Xiabin Jing; Fosong Wang, Dalton Transactions, 2014

A series of solution processible greenish-blue-emitting Ir dendrimers with polyether dendrons that consist of N-phenylcarbazole (NPC) are developed via a convenient post-dendronization method. It involves two steps: (i) the successful preparation of a reactive Ir core, namely m-HO-dfppyIr, only ...


Band gap grading and photovoltaic performance of solution-processed Cu(In,Ga)S2 thin-film solar cells

26-11-2014 | So Hyeong Sohn; Noh Soo Han; Yong Jin Park; Seung Min Park; Hee Sang An; Dong-Wook Kim; Byoung Koun Min; Jae Kyu Song, Physical Chemistry Chemical Physics, 2014

The photophysical properties of CuInxGa1−xS2 (CIGS) thin films, prepared by solution-based coating methods, are investigated to understand the correlation between the optical properties of these films and the electrical characteristics of solar cells fabricated using these films. Photophysical ...


“Bio-glues” to enhance slipperiness of mucins: improved lubricity and wear resistance of porcine gastric mucin (PGM) layers assisted by mucoadhesion with chitosan

26-11-2014 | Nikolaos Nikogeorgos; Petr Efler; A. Basak Kayitmazer; Seunghwan Lee, Soft Matter, 2014

A synergetic lubricating effect between porcine gastric mucin (PGM) and chitosan based on their mucoadhesive interaction is reported at a hydrophobic interface comprised of self-mated polydimethylsiloxane (PDMS) surfaces. In acidic solution (pH 3.2) and low concentrations (0.1 mg mL−1), the ...


Metal Sulfide Precursor Aqueous Solutions for Fabrication of Cu2ZnSn(S,Se)4 Thin Film Solar Cells

26-11-2014 | Qingwen Tian; Lijian Huang; Wangen Zhao; Yanchun Yang; Gang Wang; Daocheng Pan, Green Chemistry, 2014

Aqueous solution deposition of metal chalcogenide semiconductor thin films is considered a green and low-cost approach. However, it is hard to find a general aqueous solution approach to deposit various kinds of high-quality metal sulfide thin films. Here, we describe a green and robust ammonium ...


Bubble-Surface Interactions with Graphite in the Presence of Adsorbed Carboxymethylcellulose

26-11-2014 | Jueying Wu; Iliana Delcheva; Yung Ngothai; Marta Krasowska; David Beattie, Soft Matter, 2014

The adsorption of carboxymethylcellulose (CMC), and the subsequent effect on bubble-surface interactions, has been studied for a graphite surface. CMC adsorbs on highly oriented pyrolytic graphite (HOPG) in specific patterns: when adsorbed from a solution of low concentration it forms stretched, ...


Investigating Acid-Induced Structural Transitions of Lysozyme in an Electrospray Ionization Source

26-11-2014 | Jong Wha Lee; Hugh Inkon Kim, Analyst, 2014

The effect of acids on the structure of lysozyme (Lyz) during electrospray ionization (ESI) was studied by comparing the solution and gas-phase structures of Lyz. Investigation using circular dichroism spectroscopy and small-angle X-ray scattering demonstrated that the folded conformation of Lyz ...


Supramolecular interaction of labetalol with cucurbit[7]uril for its sensitive fluorescence detection

26-11-2014 | Changfeng Li; Jianxia Feng; Huangxian Ju, Analyst, 2014

This work studied the host–guest interaction between cucurbit[7]uril (CB[7]) and labetalol in acidic aqueous solution and proposed a simple competitive method for fluorescence detection of labetalol. The binding constant of labetalol–CB[7] was (1.83 ± 0.22) × 106 M−1, which was greater than those ...


Online photochemical vapour generation of inorganic tin for inductively coupled plasma mass spectrometric detection

26-11-2014 | Hualing Duan; Zhenbin Gong; Shifeng Yang, Journal of Analytical Atomic Spectrometry, 2014

Photochemical vapour generation (PCVG) as a sample introduction technique was adopted, for the first time, for the quantitative determination of trace levels of inorganic tin with inductively coupled plasma mass spectrometry (ICPMS). Volatile tin species could be generated online when a solution ...


NMR Studies of DNA Microcapsules Prepared By Sonochemical Methods

26-11-2014 | Irena Reytblat; Keren Adamsky; Jordan H Chill; H Gottlieb; Aharon Gedanken; Gil Goobes, Physical Chemistry Chemical Physics, 2014

DNA molecules were recently converted using ultrasonic irradiation into microcapsules that can trap hydrophobic molecules in aqueous solution. These DNA microcapsules are able to penetrate prokaryotic and eukaryotic cells, deliver drugs and transfer genetic information e.g. for protein expression ...


Hydrogen peroxide concentration by pervaporation of a ternary liquid solution in microfluidics

26-11-2014 | Iwona Ziemecka; Benoît Haut; Benoit Scheid, Lab on a Chip, 2014

Pervaporation in a microfluidic device is performed on liquid ternary solutions of hydrogen peroxide–water–methanol in order to concentrate hydrogen peroxide (H2O2) by removing methanol. The quantitative analysis of the pervaporation of solutions with different initial compositions is performed, ...
