p‐Si/SnO2/Fe2O3 Core/Shell/Shell Nanowire Photocathodes for Neutral pH Water Splitting

21-Mar-2015 | Alireza Kargar, Sung Joo Kim, Paniz Allameh, Chulmin Choi, Namseok Park, Huisu Jeong, Yusin Pak, Gun Young Jung, Xia ..., Advanced Functional Materials, 2015

Silicon is one of the promising materials for solar water splitting and hydrogen production; however, it suffers from two key factors, including the large external potential required to drive water splitting reactions at its surface and its instability in the electrolyte. In this study, a ...

In-line and selective phase separation of medium-chain carboxylic acids using membrane electrolysis

17-Mar-2015 | Jiajie Xu; Juan JL Guzman; Stephen John Andersen; Korneel Rabaey; Largus T Angenent, Chemical Communication, 2015

We had been successful in extracting a dissociated medium-chain carboxylate (n-caproate) solution from bioreactor broth. However, expensive hydroxide addition and a dilute product stream remained problematic. Here, we introduced in-line membrane electrolysis that utilized a pH gradient between ...

Solvent‐Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

17-Mar-2015 | Jeremy S. Luterbacher, David Martin Alonso, Jacqueline M. Rand, Ydna M. Questell‐Santiago, Jher Hau Yeap, Brian F. P ..., ChemSusChem, 2015

Abstract We recently reported a nonenzymatic biomass deconstruction process for producing carbohydrates using homogeneous mixtures of γ‐valerolactone (GVL) and water as a solvent. A key step in this process is the separation of the GVL from the aqueous phase, enabling GVL recycling and the ...

Device for dielectrophoretic separation and collection of nanoparticles and DNA under high conductance conditions

17-Mar-2015 | Youngjun Song, Avery Sonnenberg, Yvonne Heaney, Michael J. Heller, ELECTROPHORESIS, 2015

Most dielectrophoretic (DEP) separations of cells, nanoparticles and other entities are carried out on microelectrode arrays or in microfluidic device formats. Less work has been directed at designing pipette type formats that would allow dipping into and recovering specific analytes from ...

Electrochemical characterization of a responsive macromolecular interface on gold

13-Mar-2015 | Artur Fandrich, Jens Buller, Daniel Schäfer, Erik Wischerhoff, André Laschewsky, Fred Lisdat, physica status solidi (a), 2015

This study reports on the investigation of a thermo­responsive polymer as a thin film on electrodes and the influence of coupling a peptide and an antibody to the film. The utilized polymer from the class of poly(oligoethylene glycol)‐methacrylate polymers (poly(OEGMA)) with carboxy functions ...

Solubilization of Single-Walled Carbon Nanotubes Using a Peptide Aptamer in Water below the Critical Micelle Concentration

13-Mar-2015 | Zha Li; Tomoshi Kameda; Takashi Isoshima; Eiry Kobatake; Takeshi Tanaka; Yoshihiro Ito; Masuki Kawamoto, Langmuir, 2015

The solubilizing ability of single-walled carbon nanotubes (SWCNTs) in water with several dispersants was investigated. Among the dispersants, including low-molecular-weight surfactants, peptides, DNA, and a water-soluble polymer, the peptide aptamer, A2 (IFRLSWGTYFS), exhibited the highest ...

Controlled Synthesis of Fe3O4/ZIF‐8 Nanoparticles for Magnetically Separable Nanocatalysts

12-Mar-2015 | Fei Pang, Mingyuan He, Jianping Ge, Chemistry - A European Journal, 2015

Abstract Fe3O4/ZIF‐8 nanoparticles were synthesized through a room‐temperature reaction between 2‐methylimidazolate and zinc nitrate in the presence of Fe3O4 nanocrystals. The particle size, surface charge, and magnetic loading can be conveniently controlled by the dosage of Zn(NO3)2 and Fe3O4 ...

Synthesis of Novel Hyper‐Branched Polymers From Trimethoxysilyl‐Terminated Polylactides and Their Utilization for Modification of Poly(l‐Lactide) Materials

11-Mar-2015 | Jungyub Hyun, Chan Woo Lee, Yoshiharu Kimura, Macromolecular Materials and Engineering, 2015

Silyl‐terminated oligomers of poly(l‐lactide) (mSi‐PLLA) and poly(d‐lactide) (mSi‐PDLA) were synthesized by hydrosilylation of allyl‐terminated derivatives. They were readily hydrolyzed into hyper‐branched polymers having particulate morphology. When a mSi‐PDLA oligomer was blended with a PLLA ...

Synthesis, Structures, and Photophysical Properties of π-Expanded Oligothiophene 8-mers and Their Saturn-Like C60 Complexes

10-Mar-2015 | Hideyuki Shimizu; José D. Cojal González; Masashi Hasegawa; Tohru Nishinaga; Tahmina Haque; Masayoshi Takase; Hiroyu ..., Journal of the American Chemical Society, 2015

Two isomers of a multifunctional π-expanded macrocyclic oligothiophene 8-mer, E,E-1 and Z,Z-1, were synthesized using a McMurry coupling of a dialdehyde composed of four 2,5-thienylene and three ethynylene units under high dilution conditions. On the other hand, ...

A capillary zone electrophoresis method for the direct determination of amino acids in recombinant human erythropoietin preparations used for the treatment of anemia

09-Mar-2015 | Izabel Cristina de Souza Crespo, Matheus Troina Resende, Annibal Duarte Pereira Netto, Flávia Ferreira de Carvalho M ..., ELECTROPHORESIS, 2015

A method based on capillary zone electrophoresis for the determination of glutamic acid, glycine and alanine in a biopharmaceutical formulation containing recombinant human erythropoietin was developed. The separation was achieved within less than 5min, using a fused‐silica capillary column ...
