Two-dimensional self-assembly of diblock copolymers into nanoscopic aggregates: from dots to disks, then rings, and finally short and long rods
22-05-2013 | Xiaodong Hong; Shujuan Liu; You Wang, Soft Matter, 2013
This paper presents a simple strategy that enables the two-dimensional self-assembly of an amphiphilic polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) diblock copolymer into a variety of nanoscopic aggregates to proceed on a solid substrate. After being made by dripping several drops ...
Non-contact halogen lamp heating assisted LTP ionization miniature rectilinear ion trap: a platform for rapid on-site explosives analysis
22-05-2013 | Wendong Chen; Keyong Hou; Xingchuang Xiong; You Jiang; Wuduo Zhao; Lei Hua; Ping Chen; Yuanyuan Xie; Zhenxin Wang; H ..., Analyst, 2013
A platform consisting of a halogen lamp, a low temperature plasma (LTP) probe, and a miniature rectilinear ion trap mass spectrometer (RIT-MS) has been constructed and evaluated to detect the organic and inorganic explosives on solid surfaces. This platform features two attractive ...
Active Site of the Solvated Thiosulfate Ion Characterized by Hydration Structures and Dynamics
22-05-2013 | Montira Trinapakul; Chinapong Kritayakornupong; Anan Tongraar; Viwat Vchirawongkwin, Dalton Transactions, 2013
The reactivity of terminated sulfur atom within the thiosulfate ion involving in chemical reactions was investigated by the properties of molecular hydration shell obtained from the {\it ab initio} quantum mechanical change field molecular dynamics (QMCF MD) simulation. The average geometry ...
Highly durable and soft nanogenerator for mechanical energy harvesting
22-05-2013 | Wei Zeng; Xiaoming Tao; Song Chen; Songmin Shang; H L W Chan; Abert SH Choy, Energy & Environmental Science, 2013
Future generations of wearable electronic systems and mobile communication place a great demand for harvesting energy from ambient environments or human movements. Soft fiber-based electric power generators are attractive in meeting the requirements of wearable devices because of sufficient ...
Potentiometric sensors using cotton yarns, carbon nanotubes and polymeric membranes
22-05-2013 | Tomás Guinovart; Marc Parrilla; Gastón Adrian Crespo; F. Xavier Rius; Francisco Andrade, Analyst, 2013
A simple and generalized approach to build electrochemical sensors for wearable devices is presented. Commercial cotton yarns are first turned into electrical conductors through a simple dyeing process using a carbon nanotubes ink. These conductive yarns are then partially coated with a ...
Synthesis of bis-[small alpha],[small alpha]'-amino acids through diastereoselective bis-alkylations of chiral Ni(II)-complexes of glycine
22-05-2013 | Jiang Wang; Hong Liu; Jose Luis Acena; Daniel Houck; Ryosuke Takeda; Hiroki Moriwaki; Tatsunori Sato; Vadim A Soloshonok, Organic & Biomolecular Chemistry, 2013
The Ni(II) complex derived from glycine Schiff base with (S)-N-(benzylprolyl)-2-aminobenzophenone can be effectively alkylated with α,ω-dibromide reagents to furnish the corresponding bis-alkylated products. This method presents a direct approach for preparation of the corresponding ...
Mizoroki–Heck reactions catalyzed by palladium dichloro-bis(aminophosphine) complexes under mild reaction conditions. The importance of ligand composition on the catalytic activity
22-05-2013 | Miriam Oberholzer; Christian M. Frech, Green Chemistry, 2013
Dichloro-bis(aminophosphine) complexes of palladium with the general formula [(P{(NC5H10)3−n(C6H11)n})2Pd(Cl)2] (where n = 0–2) are easily accessible, cheap and air stable, highly active and universally applicable C–C cross-coupling catalysts, which exhibit an excellent functional group ...
Solution-cathode glow discharge – optical emission spectrometry using a compact spectrograph
22-05-2013 | Todd A. Doroski; Allison M. King; Michael P. Fritz; Michael R. Webb, Journal of Analytical Atomic Spectrometry, 2013
A solution-cathode glow discharge is coupled to a compact spectrograph. Such a coupling results in a small, potentially portable instrument that can simultaneously detect a range of metals by optical emission spectrometry. Detection limits were calculated for Ag (1 ppb), Cd (2 ppb), Cu (8 ...
A Facile and Green Synthesis Route toward Two-dimensional TiO2@Ag Heterojunction Structure with Enhanced Visible Light Photocatalytic Activity
22-05-2013 | Baojiang Jiang; Zhongwei Hou; Chungui Tian; Wei Zhou; Xian-Fa Zhang; Aiping Wu; Guohui Tian; Kai Pan; Zhiyu Ren; Hon ..., CrystEngComm, 2013
A facile and green route for the two-dimensional (2D) TiO2@Ag heterojunction structure had been developed for improving the visible light photocatalytic activity. The edible corn crispy was selected as the biomass template to fabricate 2D-TiO2@Ag heterojunction composites. The various ...
Rapid Sonogashira cross-coupling of iodoferrocenes and the unexpected cyclo-oligomerization of 4-ethynylphenylthioacetate
22-05-2013 | Michael S. Inkpen; Andrew J. P. White; Tim Albrecht; Nicholas J. Long, Chemical Communication, 2013
A systematic study into the Sonogashira cross-coupling of 1,1′-diiodoferrocene (fcI2) confirms that the Pd(0)–P(tBu)3 system provides a remarkable rate increase over Pd(0)–(PPh3)2. Attempts to couple 4-ethynylphenylthioacetate (2) with fcI2 instead produced a novel cyclic trimer of the ...
