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

06-Feb-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 ...


Sorption and Redox Speciation of Plutonium at the Illite Surface

03-Feb-2016 | Nidhu lal Banik; Rémi Marsac; Johannes Lützenkirchen; Alexandre Diascorn; Kerstin Bender; Christian Michael Marquard ..., Environmental Science & Technology, 2016

The geochemical behavior of Pu strongly depends on its redox speciation. In this study, we investigated Pu sorption onto Na–illite, a relevant component of potential host rocks for high-level nuclear waste repositories, under anaerobic conditions. When contacting Pu (85% Pu(IV), 11% Pu(V), and 4% ...


Highly Efficient Transition Metal Nanoparticle Catalysts in Aqueous Solutions

28-Jan-2016 | Changlong Wang, Roberto Ciganda, Lionel Salmon, Danijela Gregurec, Joseba Irigoyen, Sergio Moya, Jaime Ruiz, Didier ..., Angewandte Chemie International Edition, 2016

Abstract A ligand design is proposed for transition metal nanoparticle (TMNP) catalysts in aqueous solution. Thus, a tris(triazolyl)‐polyethylene glycol (tris‐trz‐PEG) amphiphilic ligand, 2, is used for the synthesis of very small TMNPs with Fe, Co, Ni, Cu, Ru, Pd, Ag, Pt, and Au. These TMNP‐2 ...


Modification of polydimethylsiloxane with polyvinylpyrrolidone: Influence of reinforcing filler on physico‐mechanical properties

28-Jan-2016 | Shib Shankar Banerjee, Indumathi Ramakrishnan, Bhabani K. Satapathy, Polymer Engineering and Science, 2016

The present article reports an approach for the modification of hydrophobic polydimethylsiloxane (PDMS) with low molecular weight hydrophilic polyvinylpyrrolidone (PVP) via solution blending method to develop new PDMS‐based materials with improved mechanical performance and wettability which can ...


Materials, Vol. 9, Pages 78: Metallurgical Parameters Controlling the Eutectic Silicon Charateristics in Be-Treated Al-Si-Mg Alloys

27-Jan-2016 | Ibrahim, Mohamed F.; Elgallad, Emad M.; Valtierra, Salvador ; Doty, Herbert W.; Samuel, Fawzy H., Materials, 2016

The present work was carried out on Al-7%Si-0.4%Mg-X alloy (where X = Mg, Fe, Sr or Be), where the effect of solidification rate on the eutectic silicon characteristics was investigated. Two solidification rates corresponding to dendrite arm spacings (DAS) of 24 and 65 μm were employed. Samples ...


Guanidinium: A Route to Enhanced Carrier Lifetime and Open-Circuit Voltage in Hybrid Perovskite Solar Cells

25-Jan-2016 | Nicholas De Marco; Huanping Zhou; Qi Chen; Pengyu Sun; Zonghao Liu; Lei Meng; En-Ping Yao; Yongsheng Liu; Andy Schif ..., Nano Letters, 2016

Hybrid perovskites have shown astonishing power conversion efficiencies owed to their remarkable absorber characteristics including long carrier lifetimes, and a relatively substantial defect tolerance for solution-processed polycrystalline films. However, nonradiative charge carrier ...


Dietary Strategies To Reduce the Bioaccessibility of Arsenic from Food Matrices

25-Jan-2016 | María Jesús Clemente; Vicenta Devesa; Dinoraz Vélez, Journal of Agricultural and Food Chemistry, 2016

The main route of exposure to arsenic (As) is the consumption of water and foods, in which the forms with greatest toxicity are inorganic As and dimethylarsinic acid, DMA(V). The objective of this study was to search for dietary components that reduce the bioaccessibility of As from food and ...


Cerium Complex‐Catalyzed Oxidation of Arylmethanols under Atmospheric Pressure of Dioxygen and Its Mechanism through a Side‐On μ‐Peroxo Dicerium(IV) Complex

21-Jan-2016 | Mitali Paul, Satoru Shirase, Yuma Morimoto, Laurent Mathey, Murugesapandian Balasubramanian, Shinji Tanaka, Shinobu ..., Chemistry - A European Journal, 2016

Abstract A new CeIV complex [Ce{NH(CH2CH2N=CHC6H2‐3,5‐(tBu)2‐2‐O)2}(NO3)2] (1), bearing a dianionic pentadentate ligand with an N3O2 donor set, has been prepared by treating (NH4)2Ce(NO3)6 with the sodium salt of ligand L1. Complex 1 in the presence of TEMPO and 4 Å molecular sieves (MS4 A) ...


Computational screening of renewably sourced polyalkylene glycol plasticizers for nylon polyamides

20-Jan-2016 | Jarod M. Younker, Raja H. Poladi, Herbert V. Bendler, Hari B. Sunkara, Polymers for Advanced Technologies, 2016

A high‐throughput computational method is used to screen new plasticizers for nylon polyamides. Condensed‐phase molecular dynamic simulations are used to describe the interaction of the plasticizer and the polymer. A radial distribution function is utilized to quantify the degree of hydrogen ...


Role of Aggregates in the Luminescence Decay Dynamics of Conjugated Polymers

20-Jan-2016 | Rajarshi Chakraborty; Lewis J Rothberg, Journal of Physical Chemistry A, 2016

Fluorescence quantum yields of conjugated polymer films are systematically lower than their counterparts in dilute solution. Films also exhibit a long “temporal tail” in their fluorescence decay dynamics not present in solution. We study the spectroscopy, excitation wavelength dependence, ...
