Chiral Monodentate Trialkylphosphines Based on the Phospholane Architecture

Nicolai Cramer, Tanguy Jean Daniel Saget, Pavel Alexandrovich Donets

The development of efficient chiral monodentate phosphine ligands lags behind that of the bidentate congeners. This holds especially true for highly electron rich chiral phosphine analogues able to replace the ubiquitous tricyclohexylphosphine and tri-tert ...

Modular synthesis of supramolecular ureidopyrimidinone–peptide conjugates using an oxime ligation strategy

Maartje Martina Cornelia Bastings

A convenient method to prepare supramolecular bioconjugates in a facile and scalable manner is by a modular approach, whereby self-assembling units and peptides are coupled using oxime chemistry. We here report syntheses of bioactive ureidopyrimidinone-bas ...

Additive Envelopes of Continuous Functions

Thomas Alois Weber

We present an iterative method for constructing additive envelopes of continuous functions on a compact set, with contact at a specified point. For elements of a class of submodular functions we provide closed-form expressions for such additive envelopes. ...

Comfusy: A Tool for Complete Functional Synthesis

Viktor Kuncak, Mikaël Mayer, Philippe Paul Henri Suter, Ruzica Piskac

Synthesis of program fragments from specifications can make programs easier to write and easier to reason about. We present Comfusy, a tool that extends the compiler for the general-purpose programming language Scala with (non-reactive) functional synthesi ...

Synthesis of Chiral Bifunctional (Thio)Urea N-Heterocyclic Carbenes

Jérôme Waser, Jonathan Brand, Jose Ignacio Osuna Siles

The rapid and modular synthesis of the first bifunctional N-heterocyclic carbenes bearing a (thio)urea moiety as H-bond donor group was reported. Different analogues could be accessed in seven steps from cheap (S)-pyroglutamic acid in good overall yields ( ...

Low power frequency synthesizer for mobile communications systems

Imre Kovacs

A novel frequency synthesizer with a strong emphasis on low-power consumption (2mW) was developed for this thesis. A BAW-resonator was used for the design of the high-frequency oscillator. The BAW's high Q-Factor ensured a minimal power consumption, while ...

Autonomous effects of shear stress and cyclic circumferential stretch regarding endothelial dysfunction and oxidative stress: an ex vivo arterial model

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Paolo Silacci, Tyler Nerton Thacher

Cyclic circumferential stretch and shear stress caused by pulsatile blood flow work in concert, yet are very different stimuli capable of independently mediating endothelial function by modulating eNOS expression, oxidative stress (via production of supero ...

Synthesis parameter space of bismuth catalyzed germanium nanowires

Anna Fontcuberta i Morral

The synthesis parameter space of bismuth catalyzed germanium nanowires by chemical vapor deposition is determined. The process window for high aspect ratio nanowires is found to be extremely narrow. The optimal conditions are found to be 300 degrees C and ...

Synthesis and biological activity of largazole and derivatives

Nicolai Cramer

A modular synthesis of the marine natural product largazole and related synthetic analogs is described. Largazole was prepd. in 10% overall yield through a synthetic route with a longest linear sequence of nine steps. Activity tests showed the necessity of ...

Growth parameters and shape specific synthesis of silicon nanowires by the VLS method

Cyril Cayron

In this paper the effect of varying temperature, pressure and chemical precursors on the vapour-liquid-solid (VLS) growth of silicon nanowires (Si NWs) have been investigated. Some aspects of nucleation and growth mechanisms are discussed. Control on Si NW ...
