Highly Enhanced Energy Conversion from the Streaming Current by Polymer Addition
22-05-2013 | Trieu Nguyen; Yanbo Xie; Lennart J. de Vreede; Albert van den Berg; Jan C.T. Eijkel, Lab on a Chip, 2013
In this contribution, we present for the first time the experimental results of energy conversion from the streaming current when polymer is added to the working solution. We added polyacrylic acid (PAA) in concentrations of 200 ppm to 4000 ppm to a KCl solution. By introducing PAA, the input ...
Facile synthesis of single crystalline gold nanoplates and SERS investigations of 4-aminothiophenol
22-05-2013 | Jianhui Yang, CrystEngComm, 2013
Single crystalline gold nanoplates with size of micrometers and tens of nanometers in thickness were synthesized by reducing HAuCl4 with disodium salt of ethylenediaminetetraacetic acid (Na2EDTA) in the presence of hexadecyltrimethylammonium bromide (CTAB) in aqueous solution. The result ...
Effect of Soy Sauce on Lipid Oxidation of Irradiated Pork Patties

3D Structure, Dynamics, and Activity of Synthetic Analog of the Peptaibiotic Trichodecenin I
17-05-2013 | Emanuela Gatto, Gianfranco Bocchinfuso, Antonio Palleschi, Simona Oncea, Marta De Zotti, Fernando Formaggio, Claudio ..., Chemistry & Biodiversity, 2013
Abstract In this contribution, we report on the conformational preferences of synthetic analogs of the antimicrobial peptide trichodecenin I in solution. This 6‐amino acid residue long peptide is characterized by a single, strongly helicogenic Aib residue in the central part of the ...
Conformational Properties of Secondary Amino Acids: Replacement of Pipecolic Acid by N‐Methyl‐L‐alanine in Efrapeptin C
17-05-2013 | Anita Dutt Konar, Elemér Vass, Miklós Hollósi, Zsuzsanna Majer, Gerhard Grüber, Katrin Frese, Norbert Sewald, Chemistry & Biodiversity, 2013
Abstract The efrapeptins, a family of naturally occurring peptides with inhibitory activities against ATPases, contain several α,α‐disubstituted α‐amino acids such as α‐aminoisobutyric acid (Aib) or isovaline (Iva) besides pipecolic acid (Pip), β‐Ala, Leu, Gly, and a C‐terminal ...
Dramatic enhancement of carbon nanotube dispersion in polyimide composites by a two‐step amino functionalization approach
17-05-2013 | Yaqin Chen, Baoping Lin, Hong Yang, Ying Sun, Xueqin Zhang, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Amino modified multiwall carbon nanotubes (MWNTs) are prepared, respectively, by two ways: the conventional one‐step method that directly treats acyl chloride functionalized MWNTs with 4, 4′‐diaminodiphenyl ether (ODA), giving the amino modified MWNT (Di‐MWNT), as well as an ...
Covalent Inhibition of Serine β-Lactamases by Novel Hydroxamic Acid Derivatives
16-05-2013 | Ronak Tilvawala; R. F. Pratt, Biochemistry, 2013
The effectiveness of β-lactam antibiotics is greatly limited by the ability of bacteria to produce β-lactamases. These enzymes catalyze the hydrolysis of β-lactams and thus loss of their antibiotic activity. The search for inhibitors of β-lactamases began soon after β-lactams were introduced ...
Derivatization following hollow‐fiber microextraction with tetramethylammonium acetate as a dual‐function regent for the determination of benzoic acid and sorbic acid by GC
15-05-2013 | Yang Sun, Xiaoqing Wang, Yilei Huang, Zaifa Pan, Lili Wang, Journal of Separation Science, 2013
Derivatization at the injection port following hollow‐fiber‐based liquid–liquid–liquid microextraction with tetramethylammonium acetate as a dual‐function regent, i.e. an acceptor and derivatization reagent, for the determination of benzoic acid (BA) and sorbic acid (SA) in real samples by ...
Intermediate Structures for Higher Level Arrangements: Catching Disk-Like Micelles in Decane Phosphonic Acid Aqueous Solutions
14-05-2013 | Erica P. Schulz; Ángel Piñeiro; José L. Rodriguez; Rosana M. Minardi; Marisa Frechero; Pablo C. Schulz, Journal of Physical Chemistry B, 2013
It has been proposed that disk-like micelles may be precursors to the formation of lamellar liquid crystals. The possibility of obtaining n-decane phosphonic acid (DPA) disk-like micelles in aqueous solution without the addition of a second ionic surfactant led us to study in detail the ...
Multifunctional Dendritic Sialopolymersomes as Potential Antiviral Agents: Their Lectin Binding and Drug Release Properties
14-05-2013 | Ali Nazemi; S. M. Mansour Haeryfar; Elizabeth R. Gillies, Langmuir, 2013
Polymer vesicles, commonly referred to as polymersomes, are self-organized materials that result from the self-assembly of amphiphilic copolymers in solution. Recently, there has been increasing interest in biomedical applications of polymersomes due to the different functions that can be ...
