Convective dynamics of traveling autocatalytic fronts in a modulated gravity field

28-10-2014 | Dezso Horvath; Marcello Antonio Budroni; Peter Baba; Laurence Rongy; Anne De Wit; Kerstin Eckert; Marcus J. B. Hause ..., Physical Chemistry Chemical Physics, 2014

When traveling in thin solution layers, autocatalytic chemical fronts may be deformed and accelerated by convective currents developing because of density and surface tension gradients related to concentration and thermal gradients across the front. On earth, both buoyancy and Marangoni related ...

Complexation mechanism of cucurbit[6]uril with hexamethylene diammonium cations in saline solution

28-10-2014 | Peng Liu; Xueguang Shao; Christophe Chipot; Wensheng Cai, Physical Chemistry Chemical Physics, 2014

Binding of cucurbit[6]uril (CB[6]) with the hexamethylene diammonium cation (HD2+) in the presence of sodium ions is elucidated at the atomic level. The most probable complex of CB[6] in saline solution is found to be CB[6]:Na+. A two-stage binding process of CB[6]:Na+ with HD2+ is proposed.

2D and 3D vanadium oxide inverse opals and hollow sphere arrays

28-10-2014 | Eileen Armstrong; Michal Osiak; Hugh Geaney; Colm Glynn; Colm O'Dwyer, CrystEngComm, 2014

High quality 2D and 3D inverse opals and hollow sphere arrays of vanadium oxide are grown on conductive substrates from colloidal polymer sphere templates formed by electrophoretic deposition or surfactant-assisted dip-coating. Inverse opals (IOs) are formed using variants of solution ...

Supramolecular Copolymer from Two-component gel: Metal Ion-Mediated Cross-Linking, Enhanced Viscoelasticity and Supramolecualr Yarn

28-10-2014 | Ling Wang; Yaqing Liu; Zhaocun Shen; Tianyu Wang; Minghua Liu, Chemical Communication, 2014

The hydrogels based on the co-assembly of bolaamphiphilic L-histidine and 2,2’-bipyridine-dicarboxylic acid have been transformed into viscoelastic supramolecular polymers by cross-linking with Cu(II) ions, and macroscopic supramolecular yarns were obtained by direct drawing from the dilute ...

Potential-Dependent Hydration Structures at Aqueous Solution/Graphite Interfaces by Electrochemical Frequency Modulation Atomic Force Microscopy

28-10-2014 | Toru Utsunomiya; Yasuyuki Yokota; Toshiaki Enoki; Ken-ichi Fukui, Chemical Communication, 2014

Potential-dependent solvation structures of aqueous electrolyte-graphite interfaces were studied using electrochemical frequency modulation atomic force microscopy. Oscillatory modulations on the force curves reversibly changed with the applied potential on the graphite electrode, and also ...

An FITC‐BODIPY FRET Couple: Application to Selective, Ratiometric Detection and Bioimaging of Cysteine

24-10-2014 | Dong Hee Ma, Dokyoung Kim, Takuya Akisawa, Kyung‐Ha Lee, Kyong‐Tai Kim, Kyo Han Ahn, Chemistry - An Asian Journal, 2014

Abstract A novel FRET couple of fluorescein is disclosed, and it was readily constructed by conjugating an amino‐BODIPY dye, a new FRET donor, with fluorescein isocyanate. Its potential was demonstrated by a fluorescence sensing system for cysteine, which was prepared by introducing acryloyl ...

Magnetically Aligned Supramolecular Hydrogels

24-10-2014 | Matthew Wallace, Andre Zamith Cardoso, William J. Frith, Jonathan A. Iggo, Dave J. Adams, Chemistry - A European Journal, 2014

Abstract The magnetic‐field‐induced alignment of the fibrillar structures present in an aqueous solution of a dipeptide gelator, and the subsequent retention of this alignment upon transformation to a hydrogel upon the addition of CaCl2 or upon a reduction in solution pH is reported. Utilising ...

N‐Heterocyclic Carbene Formation Induced Fluorescent and Colorimetric Sensing of Fluoride Using Perimidinium Derivatives

24-10-2014 | Dawei Zhang, Haiqiang Yang, Alexandre Martinez, Kelsey Jamieson, Jean‐Pierre Dutasta, Guohua Gao, Chemistry - A European Journal, 2014

Abstract In this study, two perimidinium derivatives (1 and 2) were designed, synthesized, and developed as efficient fluorescent and colorimetric chemodosisensors for F− in DMSO or more competitive media (DMSO containing 10 % water). In the presence of F−, the yellow and non‐fluorescent ...
