"Palladium-Catalyzed Diamination of Alkynes in Synthesis of Tetracycles" and "Copper-Catalyzed Cyanoalkylation of Unactivated Alkenes"

Minh Tu Ha

The thesis deals with the development of transition metal-catalyzed difunctionalization of alkenes and alkynes, which can be categorized into two major topics: (1) palladium-catalyzed diamination of alkynes for the synthesis of tetracycles; (2) copper-cata ...

Effect of a halogen-based precursor on dopant incorporation in 3C-SiC film epitaxy

Marco Negri

Silicon carbide thin films were synthesised by vapour phase epitaxy technique on silicon substrates using silane and propane as precursors. Methyltrichlorosilane (MTS) was added, and nitrogen was used as dopant precursor. Samples with different doping conc ...

Pressure drop prediction in annular two-phase flow in macroscale tubes and channels

John Richard Thome, Andrea Cioncolini

A new prediction method for the frictional pressure drop in annular two-phase flow is presented. This new prediction method focuses on the aerodynamic interaction between the liquid film and the gas core in annular flows, and explicitly takes into account ...

Fully inkjet printed SnO2 gas sensor on plastic substrate

Nico de Rooij, Danick Briand, El Hadji Malick Camara

A tin dioxide (SnO2) sensor was fabricated by inkjet printing onto polyimide foil. Gold electrodes and heater were printed on each side of the substrate. A SnO2 based ink was developed by sol-gel method and jetted onto the electrodes. A final annealing at ...

One-Pot Three-Component Synthesis of Vicinal Diamines via In Situ Aminal Formation and Carboamination

Jérôme Waser, Ugo Jonathan Orcel

A synthesis of vicinal diamines via in situ aminal formation and carboamination of allyl amines is reported. Employing highly electron-poor trifluoromethyl aldimines in their stable hemiaminal form was key to enable both a fast and complete aminal formatio ...

Neutral Aminyl Radicals Derived from Azoimidazolium Dyes

Rosario Scopelliti, Kay Severin, Henrik Moodysson Rønnow, Philip Pattison, Matthew Wodrich, Ivica Zivkovic, Andrzej Sienkiewicz, Euro Solari, Léonard Yannick Maurice Eymann, Alexander Tskhovrebov, Laurent Alexis Clément Vannay, José Luis Bila

The synthesis and characterization of a new class of neutral aminyl radicals is reported. Monoradicals were obtained by reduction of azoimidazolium dyes with potassium. Structural, spectroscopic, and computational data suggest that the spin density is cent ...

Gas Sampling Using Convection and Humidity Stabilization to Improve Point Gas Sensor Responses

Emily Ann Hammes

Many diseases including sick building syndrome, respiratory problems and cancers can be caused by exposure to high concentrations of toxins commonly used in modern building materials, paints, glues and furniture. To minimize exposure to these toxins, it is ...
