Preparation of Organotrifluoroborate Salts: Precipitation‐Driven Equilibrium under Non‐Etching Conditions

17-Aug-2012 | Alastair J. J. Lennox, Guy C. Lloyd‐Jones, Angewandte Chemie International Edition, 2012

Simple, rapid, and scaleable: In contrast to current procedures using corrosive HF/MF or MHF2 reagents (M=e.g. K), a wide range of trifluoroborates can be rapidly, simply, and safely prepared from MF (M=K, Cs), RCO2H, and a boronic acid/ester in regular glassware (see figure; left versus ...


A ruthenium-catalyzed coupling of alkynes with 1,3-diketones

13-Aug-2012 | Megan K. Pennington-Boggio, Brian L. Conley, Travis J. Williams, Journal of Organometallic Chemistry, 2012

Ruthenium(III) chloride hydrate is a convenient catalyst for the addition of active methylene compounds to aryl alkynes. These reactions are rapid, operationally simple, and high yielding in cases. Most significantly, no precautions are required to exclude air or water from the reactions. All ...


High Density Growth of Indium seeded Silicon Nanowires in the Vapor phase of a High Boiling Point Solvent

15-May-2012 | Hugh Geaney; Tadhg Kennedy; Calum Dickinson; Emma Mullane; Ajay Singh; Fathima Laffir; Kevin M. Ryan, Chemistry of Materials, 2012

Herein, we describe the growth of Si nanowires (NWs) in the vapor phase of an organic solvent medium on various substrates (Si, glass, and stainless steel) upon which an indium layer was evaporated. Variation of the reaction time allowed NW length and density to be controlled. The NWs grew via a ...


“In situ” extraction of essential oils by use of Dean–Stark glassware and a Vigreux column inside a microwave oven: a procedure for teaching green analytical chemistry

18-Apr-2012 | Farid Chemat, Sandrine Perino-Issartier, Emmanuel Petitcolas, Xavier Fernandez, Analytical and Bioanalytical Chemistry, 2012

One of the principal objectives of sustainable and green processing development remains the dissemination and teaching of green chemistry in colleges, high schools, and academic laboratories. This paper describes simple glassware that illustrates the phenomenon of extraction in a conventional ...


Topological Principles of Borosilicate Glass Chemistry

18-Oct-2011 | Morten M. Smedskjaer; John C. Mauro; Randall E. Youngman; Carrie L. Hogue; Marcel Potuzak; Yuanzheng Yue, Journal of Physical Chemistry B, 2011

Borosilicate glasses display a rich complexity of chemical behavior depending on the details of their composition and thermal history. Noted for their high chemical durability and thermal shock resistance, borosilicate glasses have found a variety of important uses from common household and ...


A serendipitous phosphonocarboxylate complex of boron: when vessel becomes reagent

09-May-2011 | Katarzyna M. Błażewska; Ralf Haiges; Boris A. Kashemirov; Frank H. Ebetino; Charles E. McKenna, Chemical Communication, 2011

Under certain conditions, the phosphonocarboxylate analogue (3) of the bisphosphonate drug minodronate (4) in contact with borosilicate glassware reversibly forms an isolable dimer complex of boron, as revealed by the X-ray crystallographic structure of the (R,R/S,S) complex and supported by NMR ...


Suspension Stability and Fractal Patterns: A Comparison using Hydroxyapatite

01-Mar-2011 | Gao, Feng; Yang, Shoufeng; Hao, Pengwei; Evans, Julian R. G., Journal of the American Ceramic Society, 2011

Hydroxyapatite suspensions were prepared in water, isopropyl alcohol, and hexadecane representing polar, semipolar, and nonpolar media, respectively. A range of dispersants were added and pH was adjusted where appropriate in an attempt to modify stability against sedimentation and hence provide ...


Surface‐Induced Synthesis and Self‐Assembly of Metal Suprastructures

06-Dec-2010 | Li, Shaozhou; Huang, Xiao; Li, Hai; Cai, Hui; Gan, Chee Lip; Boey, Freddy; Zhang, Hua, Small, 2010

Abstract A systematic study on the synthesis of a series of self‐assembled suprastructures, such as cubes, stars, belts, and microspheres, of Ag nanoparticles (AgNPs) in borosilicate glassware heavily cleaned with aqua regia is presented. These self‐assembled structures are mostly formed from ...


Investigating Acrylic Acid Polymerization by Using a Droplet‐Based Millifluidics Approach

01-Oct-2010 | Lorber, Nicolas; Pavageau, Bertrand; Mignard, Emmanuel, Macromolecular Symposia, 2010

Abstract Summary: We present herein the basic concept of droplet‐based millifluidics as an original tool to monitor polymerization kinetics. As a proof of concept, we use aqueous droplets of acrylic acid mixed with sodium persulfate at various pH as polymerization microreactor models. According ...


Laborgerätebibliotheken für ACD ChemSketch. Glassware libraries für ACD ChemSketch

01-Jul-2010 | Reiß, Philipp, CHEMKON, 2010

Die Abbildung von Versuchsaufbauten kann viele Anleitungen erheblich vereinfachen, allerdings waren die entsprechenden Gerätebibliotheken bisher nur begrenzt verfügbar. Mittlerweile gibt es für das weit verbreitete Zeichenprogramm ACD‐ChemSketch zwei kostenlose Gerätebibliotheken, mit denen ohne ...
