An in solution assay for interrogation of affinity and rational minimer design for small molecule-binding aptamers

03-Sep-2015 | Nadine Frost; Maureen McKeague; Darren Falcioni; Maria DeRosa, Analyst, 2015

Aptamers are short single-stranded oligonucleotides that fold into unique three-dimensional structures, facilitating selective and high affinity binding to their cognate targets. It is not well understood how aptamer-target interactions affect regions of structure in an aptamer, particularly for ...

Few-layer, large-area, 2D covalent organic framework semiconductor thin films

03-Sep-2015 | Jeremy I. Feldblyum; Clara H. McCreery; Sean C. Andrews; Tadanori Kurosawa; Elton J. G. Santos; Vincent Duong; Lei F ..., Chemical Communication, 2015

In this work, we synthesize large-area thin films of a conjugated, imine-based, two-dimensional covalent organic framework at the solution/air interface. Thicknesses between ∼2–200 nm are achieved. Films can be transferred to any desired substrate by lifting from underneath, enabling their use as ...

Design Mass-controllable NiCo2S4/Ketjen Black Nanocomposite Electrodes for High performance Supercapacitors

03-Sep-2015 | Tao Peng; Tieliang Zhao; Qing Zhou; Hongyan Zhou; Jun Wang; Jinyuan Liu; qi liu, CrystEngComm, 2015

NiCo2S4/Ketjen Black nanocomposites have been successfully fabricated on nikcel foam by a facile two-step solution-based method. Compared with the pure NiCo2S4 electrode (Ni1K0), the NiCo2S4/KB nanocomposite electrodes (Ni1K0.5, Ni1K0.25, Ni1K0.125) with controllable mass loadings show ...

Synthesis and Stability of Cyclic [small alpha]-Hydrogen Nitroxides

03-Sep-2015 | Hila Toledo; Michal Amar; Sukanta Bar; Mark Alan Iron; Natalia Fridman; Boris Tumanskii; Linda Shimon; Mark M Botosh ..., Organic & Biomolecular Chemistry, 2015

Nitroxides (nitroxyl radicals) hold a unique place in science due to their stable radical nature. We have recently reported the first design concept providing a general solution to the problem of designing and preparing mono cyclic α-hydrogen nitroxides. The initial works were limited to aryl ...

Mechanism of Large Stokes Shift and Aggregation-Enhanced Emission of Osmapentalyne Cation in Solution: Combined MD Simulations and QM/MM Calculations

03-Sep-2015 | Guang-Xu Sun; Ming-Gang Ju; Hang Zang; Yi Zhao; WanZhen Liang, Physical Chemistry Chemical Physics, 2015

Osmapentalyne cations synthesized recently show remarkable optical properties, such as near-infrared emission, unusual large Stokes shift and aggregation-enhanced emission. Here, the mechanisms behind those novel optical behaviors are revealed from the combined molecular dynamics simulations and ...

Simulating growth morphology of urea crystals from vapour and aqueous solution

03-Sep-2015 | Manoj Kumar Singh, CrystEngComm, 2015

The molecular-scale understanding of the mechanism through which solvent interacts with the crystal surface during crystal growth process is still a formidable challenge. The quantitative understanding at this venture has paramount interest in chemical and pharmaceutical industries in controlling ...

Dissipative Particle Dynamics Simulation Study on Self-Assembly of Amphiphilic Hyperbranched Multiarm Copolymers with Different Degrees of Branching

02-Sep-2015 | Haina Tan; Wei Wang; Chunyang Yu; Yongfeng Zhou; Zhong-Yuan Lu; Deyue Yan, Soft Matter, 2015

Hyperbranched multiarm copolymers (HMCs) have shown great potentials to be excellent precursors in self-assembly to form various supramolecular structures in all scales and dimensions in solution. However, theoretical studies on the self-assembly of HMCs, especially the self-assembly dynamics and ...

Reductive amination of furfural to furfurylamine using aqueous ammonia solution and molecular hydrogen: an environmentally friendly approach

02-Sep-2015 | Maya Chatterjee; Takayuki Ishizaka; Hajime Kawanami, Green Chemistry, 2015

A simple and highly efficient method was developed for the transformation of furfural (a biomass derived aldehyde) to furfurylamine by reductive amination using an aqueous solution of ammonia and molecular hydrogen as an amine source and a reducing agent, respectively. By choosing a suitable ...

Extensional viscosity of copper nanowire suspensions in an aqueous polymer solution

02-Sep-2015 | Amarin George McDonnell; Naveen N. Jason; Leslie Yeo; James R. Friend; Wenlong Cheng; Prabhakar Ranganathan, Soft Matter, 2015

Suspensions of copper nanowires are emerging as new electronic inks for next-generation flexible electronics. Using a novel surface acoustic wave driven extensional flow technique we are able to perform currently lacking analysis of these suspensions and their complex buffer. We observe ...

A chemical method for stabilizing a new series of solid solution in Pr1-xCexScO3 (0.0 [less-than-or-equal] x [less-than-or-equal] 1.0) system

02-Sep-2015 | Farheen N Sayed; Rakesh R Shukla; A. K. Tyagi, Dalton Transactions, 2015

A new series of Pr1-xCexScO3 (0.0 ≤ x ≤ 1.0) compounds was synthesized by a two-step synthesis route, involving combustion reaction followed by reduction while heating in low partial pressure of O2, generated by zirconium sponge that acts as an oxygen getter. For the first time, a perovskite ...
