Chirality‐Selective Photoluminescence Enhancement of ssDNA‐Wrapped Single‐Walled Carbon Nanotubes Modified with Gold Nanoparticles

29-Apr-2016 | Juan Yang, Qinghua Zhao, Min Lyu, Zhenyu Zhang, Xiao Wang, Meng Wang, Zhou Gao, Yan Li, Small, 2016

In this work, a convenient method to enhance the photoluminescence (PL) of single‐walled carbon nanotubes (SWNTs) in aqueous solutions is provided. Dispersing by single‐stranded DNA (ssDNA) and modifying with gold nanoparticles (AuNPs), about tenfold PL enhancement of the SWNTs is observed. More ...

Commercial Copper Foam as an Effective 3D Porous Electrode for Nonenzymatic Glucose Detection

29-Apr-2016 | Lili Bie, Xue Luo, Luqi Kang, Daiping He, Ping Jiang, Electroanalysis, 2016

Abstract Commercially available copper foam (CF) was used as a 3D porous electrochemical sensing platform for nonenzymatic glucose detection. CF shows high electrocatalytic activity towards glucose oxidation and can be used directly for glucose electrochemical sensing without any pretreatment. ...

Iron oxide nanotube film formed on carbon steel for photoelectrochemical water splitting: effect of annealing temperature

29-Apr-2016 | Hongda Deng, Mao‐Chia Huang, Wei‐Heng Weng, Jing‐Chie Lin, Surface and Interface Analysis, 2016

Carbon steels (CSs) were anodized in an ethylene glycol solution containing 3 vol.% H2O and 0.1 m NH4F to coat with nanotube arrays film. The as anodized nanotube arrays film were annealed in argon atmosphere at various temperatures ranging from 250 to 550 °C for 4 h. The morphology and crystal ...

Aqueous Solution-Based Fe3O4 Seed-Mediated Route to Hydrophilic Fe3O4–Au Janus Nanoparticles

29-Apr-2016 | Chenjing Jin; Yun Qu; Minggui Wang; Jie Han; Yimin Hu; Rong Guo, Langmuir, 2016

Hydrophilic Fe3O4–Au Janus nanoparticles have been synthesized through a facile aqueous solution-based Fe3O4 seed-mediated chemical reduction route, where Au nanoparticles can be in situ formed on surfaces of PVP-modified Fe3O4 nanoparticles by adopting the well-known citrate reduction route. The ...

New Perspectives on the Charging Mechanisms of Supercapacitors

29-Apr-2016 | Alexander C. Forse; Céline Merlet; John M. Griffin; Clare P. Grey, Journal of the American Chemical Society, 2016

Supercapacitors (or electric double-layer capacitors) are high-power energy storage devices that store charge at the interface between porous carbon electrodes and an electrolyte solution. These devices are already employed in heavy electric vehicles and electronic devices, and can complement ...

Mixed‐halide CH3NH3PbI3‐xXx (X = Cl, Br, I) perovskites: Vapor assisted solution deposition and application as solar cell absorbers

28-Apr-2016 | Rahime Sedighi, Fariba Tajabadi, Saeed Shahbazi, Somayeh Gholipour, Nima Taghavinia, ChemPhysChem, 2016

There have been recent reports on the formation of single halide perovskites CH3NH3PbX3 (X= Cl, Br, I) using vapor assisted solution processing. Herein, we report successful formation of mixed halide perovskites (CH3NH3PbI3‐xXx) using a vapor assisted solution method at ambient atmosphere. The ...

Employing Core‐Shell Quantum Dots as Triplet Sensitizers for Photon Upconversion

28-Apr-2016 | Keisuke Okumura, Kazuma Mase, Nobuhiro Yanai, Nobuo Kimizuka, Chemistry - A European Journal, 2016

Abstract A new family of surface‐functionalized CdSe/ZnS core‐shell quantum dots (csQD) has been developed, which work as triplet sensitizers for triplet‐triplet annihilation‐based photon upconversion (TTA‐UC). The surface modification of csQD with acceptor molecules plays a key role in the ...

Separation and Detection of Amino Acid Metabolites of Escherichia Coli in Microbial Fuel Cell with Capillary Electrophoresis

28-Apr-2016 | Wei Wang, Lihong Ma, Ping Lin, Kaixuan Xu, ELECTROPHORESIS, 2016

In this work, CE‐LIF was employed to investigate the amino acid metabolites produced by Escherichia coli (E coli) in microbial fuel cell (MFC). Two peptides, L‐carnosine and L‐alanyl‐glycine, together with six amino acids, cystine, alanine, lysine, methionine, tyrosine, arginine were separated ...

Advanced High‐Voltage Aqueous Lithium‐Ion Battery Enabled by “Water‐in‐Bisalt” Electrolyte

27-Apr-2016 | Liumin Suo, Oleg Borodin, Wei Sun, Xiulin Fan, Chongyin Yang, Fei Wang, Tao Gao, Zhaohui Ma, Marshall Schroeder, Art ..., Angewandte Chemie International Edition, 2016

Abstract A new super‐concentrated aqueous electrolyte is proposed by introducing a second lithium salt. The resultant ultra‐high concentration of 28 m led to more effective formation of a protective interphase on the anode along with further suppression of water activities at both anode and ...
