Dual-responsive vesicles formed by an amphiphile appended two tetrathiafulvalene units in aqueous solution

25-Nov-2015 | Li-Zhu Wu; Xiao-Jun Wang; Ling-Bao Xing; Bin Chen; Ying Quan; Chen Ho Tung, Organic & Biomolecular Chemistry, 2015

The first example of tetrathiafulvalene (TTF)-based vesicle fabricated in water solution with 1 vol% tetrahydrofuran that could be prevented by chemical oxidant Fe(ClO4)3 or electron-deficient cyclobis(paraquat-p-phenylene) tetracation cyclophane (CBPQT4+) is described.


Optofluidic tunable lenses using laser-induced thermal gradient

25-Nov-2015 | Qingming Chen; Aoqun Jian; Zhaohui Li; Xuming Zhang, Lab on a Chip, 2015

This paper reports a new design of optofluidic tunable lens using a laser-induced thermal gradient. It makes use of two straight chromium strips at the bottom of the microfluidic chamber to absorb the continuous pump laser to heat up the moving benzyl alcohol solution, creating a 2D refractive ...


In situ 2D-extraction of DNA wheels by 3D through-solution transport

25-Nov-2015 | Yusuke Yonamine; Keitel Cervantes-Salguero; Waka Nakanishi; Ibuki Kawamata; Kosuke Minami; Hirokazu Komatsu; Satoshi ..., Physical Chemistry Chemical Physics, 2015

Controlled transfer of DNA nanowheels from a hydrophilic to a hydrophobic surface was achieved by complexation of the nanowheels with a cationic lipid (2C12N+). 2D surface-assisted extraction, ‘2D-extraction’, enabled structure-persistent transfer of DNA wheels, which could not be achieved by ...


A Light Sensitive Self-Assembled Nanogel as a Tecton for Protein Patterning Materials.

25-Nov-2015 | Tomoki Nishimura; Masahiro Takara; Sada-atsu Mukai; Shin-ichi Sawada; Yoshihiro Sasaki; Kazunari Akiyoshi, Chemical Communication, 2015

A self-assembled nanogel is constructed from light-sensitive cholesteryl pullulan (Ls-CHP) by using photo-labile ortho-nitrobenzyl (o-NB) units. The nanogel-based film is obtained by evaporation of the Ls-CHP nanogel solution. Exposure of the resulting nanogel-based film to light with a mask ...


Electrochemically aminated glassy carbon electrode for simultaneous determination of hydroquinone and catechol

25-Nov-2015 | xiuyun wang; Min Xi; Mengmeng Guo; Fangmeng Sheng; Guang Xiao; Shuo Wu; Shunichi Uchiyama; Hiroaki Matsuura, Analyst, 2015

In this contribution, a very simple and reliable strategy based on the easy modification of glassy carbon electrode (GCE) by pre-electrolyzing GCE in ammonium carbamate aqueous solution was employed for the simultaneous determination of hydroquinone (HQ) and catechol (CC). Compared with bare GCE, ...


A flow visualization and superposition rheology study of shear-banding wormlike micelle solutions

25-Nov-2015 | Hadi Mohammadigoushki; Susan J. Muller, Soft Matter, 2015

In this paper, we use rheometry and flow visualization to study the dynamics of the interface between shear bands in a wormlike micellar solution sheared between concentric cylinders, i.e., in a Taylor–Couette (TC) cell, and to evaluate the stress diffusion coefficient and the stress correlation ...


Accordion-like swelling of layered perovskite crystals via massive permeation of aqueous solutions into 2D oxide galleries

25-Nov-2015 | Yeji Song; Nobuo Iyi; Tatsumasa Hoshide; Tadashi C. Ozawa; Yasuo Ebina; Renzhi Ma; Nobuyoshi Miyamoto; Takayoshi Sasaki, Chemical Communication, 2015

Platelet crystals of a layered perovskite showed massive accordion-like swelling in a tetrabutylammonium hydroxide solution. The permeation of the solution induced the huge expansion of the interlayer spacing as well as the crystal thickness up to 50-fold, leading to a very high water content of


Phototransformation-Pattern of Antiplatelet Drug Tirofiban in Aqueous Solution, Relevant To Drug Delivery and Storage.

25-Nov-2015 | Théo Henriet; Philippe Henri Secretan; Fatma Amrani; Hassane Sadou-Yaye; Mélisande Bernard; Audrey Solgadi; Najet Ya ..., New Journal of Chemistry, 2015

Tirofiban is a synthetic, nonpeptidic fibrinogen receptor antagonist used as antiplatelet drug by intravenous delivery. As the active pharmaceutical ingredient may undergo light exposure during manufacturing, storage and/or delivery, there is a need to acquire an extensive knowledge of its major ...


On the stability of foams made with surfactant bilayer phases

25-Nov-2015 | Zenaida Briceño; Amir Maldonado; Marianne Imperor-Clerc; D Langevin, Soft Matter, 2015

The stability of foams made with sponge phases (L3 phases) and lamellar phases (L phases), both containing surfactant bilayers, has been investigated. The extreme stability of foams made with lamellar phases seems essentially due to the high viscosity of the foaming solution, which slows down ...


Nickel Cobalt Phosphides Quasi-Hollow Nanocubes as an Efficient Electrocatalyst for Hydrogen Evolution in Alkaline Solution

25-Nov-2015 | Yi Feng; Xinyao Yu; Ungyu Paik, Chemical Communication, 2015

A template-engaged strategy is used to synthesize nanostructured metal phosphides with different compositions. Among the as-synthesized metal phosphides, nickel cobalt phosphides quasi-hollow nanocubes exhibit the best electrocatalytic activity for hydrogen evolution reaction in terms of lower ...
