Digitization of multistep organic synthesis in reactionware for on-demand pharmaceuticals

19-Jan-2018 | Philip J. Kitson; Guillaume Marie; Jean-Patrick Francoia; Sergey S. Zalesskiy; Ralph C. Sigerson; Jennifer S. Mathie ..., Science , 2018

The infrastructure for chemical synthesis typically lies at either end of a spectrum: small-scale studies in ad hoc assemblies of glassware or large-scale production in capital-intensive custom reactors. Kitson et al. report a hybrid protocol that customizes a blueprint for synthesis of a target ...

Visible‐light Emulsion Photopolymerization of Styrene

06-Dec-2017 | Frédéric Le Quéméner, Daniel Subervie, Fabrice Morlet-Savary, Jacques Lalevée, Muriel Lansalot, Elodie Bourgeat-Lami ..., Angewandte Chemie International Edition, 2017

The photopolymerization of styrene in emulsion is achieved in a conventional double wall reactor equipped with a LED ribbon coiled around the external glass wall. Styrene mixed to acridine orange is added to the water phase containing sodium dodecyl sulfate, a water‐soluble N‐heterocyclic ...

Dust Effects on Nucleation Kinetics and Nanoparticle Product Size Distributions: Illustrative Case Study of a Prototype Ir(0)n Transition-Metal Nanoparticle Formation System

22-Jun-2017 | Saim Özkar; Richard G. Finke, Langmuir, 2017

The question is addressed if dust is kinetically important in the nucleation and growth of Ir(0)n nanoparticles formed from [Bu4N]5Na3(1,5-COD)IrI·P2W15Nb3O62 (hereafter [(COD)Ir·POM]8–), reduced by H2 in propylene carbonate solvent. Following a concise review of the (often-neglected) literature ...

Closed‐System One‐Pot Block Copolymerization by Temperature‐Modulated Monomer Segregation

03-Jun-2016 | R. Nicholas Carmean, C. Adrian Figg, Troy E. Becker, Brent S. Sumerlin, Angewandte Chemie International Edition, 2016

Abstract A biphasic one‐pot polymerization method enables the preparation of block copolymers from monomers with similar and competitive reactivities without the addition of external materials. AB diblock copolymers were prepared by encapsulating a frozen solution of monomer B on the bottom of ...

Problems and Pitfalls in the Analysis of Amygdalin and Its Epimer

02-Oct-2015 | M. Farooq Wahab; Zachary S. Breitbach; Daniel W. Armstrong; Rick Strattan; Alain Berthod, Journal of Agricultural and Food Chemistry, 2015

α-[(6-O-β-d-Glucopyranosyl-β-d-glucopyranosyl)oxy]-(αR)-benzeneacetonitrile, or R-amygdalin, is the most common cyanogenic glycoside found in seeds and kernels of the Rosaceae family and other plant genera such as Passiflora. Many commercially important seeds are analyzed for amygdalin content. ...

Pretreatment of Nitric Acid with Hydrogen Peroxide Reduces Total Procedural Os Blank to Femtogram Levels

09-Jul-2015 | Gang Yang; Aaron Zimmerman; Holly Stein; Judith Hannah, Analytical Chemistry, 2015

Determining and correcting for background contributions of Re and Os from chemical reagents is critical for accurate and precise Re–Os dating of materials with parts per billion to parts per trillion Re and Os concentrations. Here we investigate reducing Os content in nitric acid, as it is the ...

Combined analysis of enamelled and gilded glassware from Frederick II Castle at Melfi (Italy) to identify technology and raw materials

23-Feb-2015 | Maria Cristina Caggiani, Nicoletta Ditaranto, Maria Rachele Guascito, Pasquale Acquafredda, Rocco Laviano, Lorena Ca ..., X-Ray Spectrometry, 2015

A group of enamelled and gilded glass objects, coming from Melfi Castle (PZ ‐ Italy) from an area dated to the period between the end of the 12th and the last quarter of the 13th century, offered the opportunity to closely investigate this technology with the aim of understanding the raw ...

Synthesis of Tin Catalyzed Silicon and Germanium Nanowires in a Solvent–Vapor System and Optimization of the Seed/Nanowire Interface for Dual Lithium Cycling

04-Apr-2013 | Emma Mullane; Tadhg Kennedy; Hugh Geaney; Calum Dickinson; Kevin M. Ryan, Chemistry of Materials, 2013

Silicon and germanium nanowires are grown in high density directly from a tin layer evaporated on stainless steel. The nanowires are formed in low cost glassware apparatus using the vapor phase of a high boiling point organic solvent as the growth medium. HRTEM, DFSTEM, EELS, and EDX analysis ...

IJERPH, Vol. 9, Pages 4068-4082: Drunk and Disorganised: Relationships between Bar Characteristics and Customer Intoxication in European Drinking Environments

12-Nov-2012 | Hughes, Karen ; Quigg, Zara ; Bellis, Mark A. ; Calafat, Amador ; Hasselt, Ninette van ; Kosir, Matej ; Voorham, Lot ..., International Journal of Environmental Research and Public Health, 2012

Preventing alcohol-related harm in drinking environments is a growing international priority. Factors relating to the physical, social and staffing environments in bars can contribute to increased alcohol consumption and harm. Understanding the relationships between such factors and intoxication ...
