One-step fabrication of ultralong nanobelts of PI-PTCDI and its optoelectronic properties

21-10-2014 | Bo Yang; fengxia wang; Kai-Kai Wang; Jinghui Yan; yongqiang Liu; Ge-Bo Pan, Physical Chemistry Chemical Physics, 2014

The ultralong nanobelts of N,N-bis-(1-propylimidazole)-3,4,9,10-perylene tetracarboxylic diimide (PI-PTCDI) were fabricated by one-step solution process. The prototype devices based on the PI-PTCDI nanobelts exhibited excellent photodetector and photoswitching performance. The highest Ion/Ioff ...

Sol-gel deposited Cu2O and CuO thin films for photocatalytic water splitting

21-10-2014 | Yee-Fun Lim; Chin Sheng Chua; Coryl Jing Jun Lee; Dongzhi Chi, Physical Chemistry Chemical Physics, 2014

Cu2O and CuO are attractive photocatalytic materials for water splitting due to their Earth-abundance and low cost. In this paper, we report the deposition of Cu2O and CuO thin films by a sol-gel spin-coating process. Sol-gel deposition has distinctive advantages such as low-cost solution ...

Solution structure of a cucurbit[8]uril induced compact supramolecular protein dimer

21-10-2014 | Dang Dang; Ralph Bosmans; Christian Moitzi; Ilja Karina Voets; Luc Brunsveld, Organic & Biomolecular Chemistry, 2014

Supramolecular assembly of a beta-barrel protein via cucurbit[8]uril results in compact z-shaped protein dimers. SAXS data reveal the formation of a well ordered protein dimer, notwithstanding being connected by a reversible and flexible peptide linker, and highlight the supramolecular induced ...

Model-potential-free analysis of small angle scattering of proteins in solution: insights into solvent effects on protein-protein interaction

21-10-2014 | Tomonari Sumi; Hiroshi Imamura; Takeshi Morita; Yasuhiro Isogai; Keiko Nishikawa, Physical Chemistry Chemical Physics, 2014

To extract protein-protein interaction from experimental small-angle scattering of proteins in solutions using liquid state theory, a model potential consisted of a hard-sphere repulsive potential and the excess interaction potential has been introduced. In the present study, we propose a ...

Luminescence Color Tuning of PtII Complexes and a Kinetic Study of Trimer Formation in the Photoexcited State

20-10-2014 | T. Kayano, S. Takayasu, K. Sato, K. Shinozaki, Chemistry - A European Journal, 2014

Abstract We investigated the luminescence properties and color tuning of [Pt(dpb)Cl] (dpbH=1,3‐di(2‐pyridyl)benzene) and its analogues. An almost blue emission was obtained for the complex [Pt(Fmdpb)CN] (FmdpbH=4‐fluoro‐1,3‐di(4‐methyl‐2‐pyridyl)benzene), modified by the introduction of F and ...

Efficient Coupling of Solar Energy to Catalytic Hydrogenation by Using Well‐Designed Palladium Nanostructures

20-10-2014 | Ran Long, Zhoulv Rao, Keke Mao, Yu Li, Chao Zhang, Qiliang Liu, Chengming Wang, Zhi‐Yuan Li, Xiaojun Wu, Yujie Xiong, Angewandte Chemie International Edition, 2014

Abstract A Ru3+‐mediated synthesis for the unique Pd concave nanostructures, which can directly harvest UV‐to‐visible light for styrene hydrogenation, is described. The catalytic efficiency under 100 mW cm−2 full‐spectrum irradiation at room temperature turns out to be comparable to that of ...

Effect of fiber size on structural and tensile properties of electrospun polyvinylidene fluoride fibers

18-10-2014 | Avinash Baji, Yiu‐Wing Mai, Shing‐Chung Wong, Polymer Engineering and Science, 2014

We use electrospinning to obtain polyvinylidene fluoride (PVDF) fibers and demonstrate simultaneous improvements in β‐crystal microstructure and in tensile properties of fibers with reduction of their diameter. PVDF fibers with average diameters ranging from 70 to 400 nm are obtained by ...

Electrical conductivity and tensile properties of block‐copolymer‐wrapped single‐walled carbon nanotube/poly(methyl methacrylate) composites

18-10-2014 | Alejandro Ansón‐Casaos, F. Javier Pascual, Cristina Ruano, Natalia Fernández‐Huerta, Isaías Fernández‐Pato, Juan C. ..., Journal of Applied Polymer Science, 2014

ABSTRACT Poly(methyl methacrylate) (PMMA) composites containing raw or purified single‐walled carbon nanotubes (SWCNTs) are prepared by in situ polymerization and solution processing. The SWCNTs are purified by centrifugation in a Pluronic surfactant, which consists of polyethyleneoxide and ...

Preparation and evaluation of nonphosphate terpolymer as scale inhibitor and dispersant for Ca3(PO4)2, BaSO4, and Iron (III) hydroxide scales

18-10-2014 | Yunyun Bu, Yuming Zhou, Qingzhao Yao, Yiyi Chen, Wei Sun, Wendao Wu, Journal of Applied Polymer Science, 2014

ABSTRACT The polymeric scale inhibition and dispersion agents (PAYS) were prepared by graft copolymerization of acrylic acid, allylpolyethoxy carboxylate (APEY) and 2‐acrylamido‐2‐methyl‐propanesulfonic acid by using ammonium persulfate as a radical initiator in aqueous solution, among which ...
