Sensors, Vol. 16, Pages 219: Poly(Ionic Liquid) Semi-Interpenetrating Network Multi-Responsive Hydrogels

06.02.2016 | Tudor, Alexandru ; Florea, Larisa ; Gallagher, Simon ; Burns, John ; Diamond, Dermot, Sensors, 2016

Herein we describe poly(ionic liquid) hydrogel actuators that are capable of responding to multiple stimuli, namely temperature, ionic strength and white light irradiation. Using two starting materials, a crosslinked poly ionic liquid (PIL) and a linear ...

Chloride and Indium‐Chloride‐Complex Inorganic Ligands for Efficient Stabilization of Nanocrystals in Solution and Doping of Nanocrystal Solids

05.02.2016 | Vladimir Sayevich, Chris Guhrenz, Maria Sin, Volodymyr M. Dzhagan, Alexander Weiz, Daniel Kasemann, Eike Brunner, Mi ..., Advanced Functional Materials, 2016

Here, the surface functionalization of CdSe and CdSe/CdS core/shell nanocrystals (NCs) with compact chloride and indium‐chloride‐complex ligands is reported. The ligands provide not only short interparticle distances but additionally control doping and passivation of surface trap states, leading ...

Unveiling the Mode of Interaction of Berberine Alkaloid in Different Supramolecular Confined Environments: Interplay of Surface Charge between Nano-Confined Charged Layer and DNA

05.02.2016 | Niloy Kundu; Arpita Roy; Debasis Banik; Nilmoni Sarkar, Journal of Physical Chemistry B, 2016

In this Article, we demonstrate a detailed characterization of binding interaction of berberine chloride (BBCl) with calf-thymus DNA (CT-DNA) in buffer solution as well as in two differently charged reverse micelles (RMs). The photophyscial properties of this alkaloid have been modulated within ...

ChemInform Abstract: Creating Reactivity with Unstable Endmembers Using Pressure and Temperature: Synthesis of Bulk Cubic Mg0.4Fe0.6N.

04.02.2016 | George Serghiou, Gang Ji, Nicholas Odling, Hans J. Reichmann, Jean‐Paul Morniroli, Reinhard Boehler, Dan J. Frost, J ..., ChemInform, 2016

Abstract A novel rock salt Mg0.4Fe0.6N solid solution is obtained by hot pressing a 70:30 at.% mixture of Fe and Mg together with NaN3 (MgO capsule in multianvil cell, 15 GPa, 1800 K, 1 min).

Ultrasensitive pH-Induced Water Solubility Switch Using UCST Polymers

04.02.2016 | Hu Zhang; Shengwei Guo; Weizheng Fan; Yue Zhao, Macromolecules, 2016

For some thermosensitive polymers, the absence of an upper critical solution temperature (UCST) in water in an accessible temperature range (say, 5–90 °C) can be attributed to the influence of charged groups in the polymer structure. This property was exploited in the present study to achieve ...

Dextran‐Coated Antiferromagnetic MnO Nanoparticles for a T1‐MRI Contrast Agent with High Colloidal Stability

03.02.2016 | Herbert R. Neves, Rafael A. Bini, Jeam H. O. Barbosa, Carlos E. G. Salmon, Laudemir C. Varanda, Particle & Particle Systems Characterization, 2016

A simple approach to synthesize carboxymethyl dextran‐coated MnO nanoparticles (CMDex‐MnONPs) with high colloidal stability in physiological saline solutions is described here for potential applications as a magnetic resonance imaging (MRI) T1 contrast agent. The thermal decomposition ...

Multiferroic broken by commensurate magnetic ordering

02.02.2016 | Guo Bao Li, Hao Zhang, Roxana Flacau, Xin Du, Pascal Manuel, Junzhuang Cong, Young Sun, Junliang Sun, Sihai Yang, Fu ..., ChemPhysChem, 2016

TbMnO3 is an important multiferroic showing strong coupling between magnetic and ferroelectric orderings. Incommensurate magnetic ordering is suggested to be vital for this coupling in TbMnO3, which can be modified by doping at the site of Tb and/or Mn. Our study shows that a self‐doped solid ...

Phosphidoboratabenzene–rhodium(I) complexes as precatalysts for the hydrogenation of alkenes at room temperature and atmospheric pressure

02.02.2016 | Viridiana Perez; Pierre Audet; Wenhua Bi; Frédéric-Georges Fontaine, Dalton Transactions, 2016

The di-tert-butylphosphido-boratabenzene ligand (DTBB) reacts with [(C2H4)2RhCl]2 yielding the dimeric species [(C2H4)Rh(DTBB)]2 (1). This species was fully characterized by multinuclear NMR and X-ray crystallography. Complex 1 readily dissociates ethylene in solution and upon exposure to 1 atm ...

Hierarchical Sol–Gel Transition Induced by Thermosensitive Self-Assembly of an ABC Triblock Polymer in an Ionic Liquid

02.02.2016 | Yuzo Kitazawa; Takeshi Ueki; Lucas D. McIntosh; Saki Tamura; Kazuyuki Niitsuma; Satoru Imaizumi; Timothy P. Lodge; M ..., Macromolecules, 2016

We investigated a hierarchical morphology change and accompanying sol–gel transition using a doubly thermosensitive ABC-triblock copolymer in an ionic liquid (IL). The triblock copolymer contains two different lower critical solution temperature (LCST) thermosensitive polymers, poly(benzyl ...

Intraband Luminescence from HgSe/CdS Core/Shell Quantum Dots

01.02.2016 | Zhiyou Deng; Philippe Guyot-Sionnest, ACS Nano, 2016

HgSe/CdS core/shell CQD are synthesized, and the changes in the optical absorption and luminescence are investigated. While HgSe quantum dots are naturally n-doped after synthesis, both as colloidal solutions and as films, the HgSe/CdS core/shell dots in solution lose the n-doping, as seen from ...
