Fluorophores for Excited-State Intramolecular Proton Transfer by an Yttrium Triflate Catalyzed Reaction of Isocyanides with Thiocarboxylic Acids

Qian Wang, Jieping Zhu, Shuo Tong, Shun Zhao, Qing He

Discovery of new chemical reactivity of a given functional group can often result in innovative synthesis of important chemical entities that possess unprecedented properties. We designed and developed a one-step synthesis of 5-amino-4-carboxamidothiazoles ...

Quantum state resolved gas–surface reaction dynamics experiments: a tutorial review

Rainer Beck, Helen Jane Chadwick

We present a tutorial review of our quantum state resolved experiments designed to study gas–surface reaction dynamics. The combination of a molecular beam, state specific reactant preparation by infrared laser pumping, and ultrahigh vacuum surface analysi ...

Application of Ionic Liquids in the Downstream Processing of Lignocellulosic Biomass

Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

Chemical transformations of lignocellulosic substrates to valuable platform chemicals are challenging as lignin and cellulose have high thermal and chemical stabilities. However, certain ionic liquids are able to dissolve and deconstruct biomass and, in th ...

Homogenous catalytic hydrogenation of bicarbonate with water soluble aryl phosphine ligands

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis

The chemical transformation of CO2 and bicarbonates into useful products becomes increasingly impor- tant as the atmospheric CO2 level has reached 400 ppm. Here a small library of sulfonated aryl mono- phosphines and aryl diphosphines was tested as stabili ...

Reversible hydrogen storage in Mg(BH4)(2)/carbon nanocomposites

Mg(BH4)2 exhibits a high hydrogen content of 14.9 wt% and thermodynamic stability in the overall decomposition reaction that corresponds to hydrogen desorption at around room temperature. However, the potential applications in hydrogen storage are restrict ...

Cu-based p-type Oxide Photocathodes for Solar Hydrogen Production

Adriana Paracchino

The actualization of a hydrogen economy requires cost-effective and environmentally benign solutions to hydrogen production. Chemical energy in the form of hydrogen is more interesting than electricity to satisfy our ever-increasing energy demand because i ...

New synthetic seven-membered 1-azasugars displaying potent inhibition towards glycosidases and glucosylceramide transferase

Pierre Vogel, Claudia Bello, Sylvain Favre, Tao Liu

Several members of a new family of seven-membered azasugars, which can be seen as 1-azasugar ring homologues, have been I obtained by simple chemical transformations starting from a sugar-derived azidolactol. Unlike their piperidine counterparts, these mol ...

Er-Yb waveguide amplifiers in novel silicate glasses

Jana Jágerská

A set of novel silicate glasses containing ZnO and co-doped with Er3+ and Yb3+ was designed as substrates for optical waveguide amplifiers. Characterized by exceptionally low up-conversion, minimum Er concentration quenching and high mechanical as well as ...

Characterization of perfluorodecanoate self-assembled monolayers on aluminum and comparison of stability with phosphonate and siloxy self-assembled monolayers

The long term performance of micro-/nano-electromechanical systems (MEMS/NEMS) depends on their stability to operating conditions, contact friction, adhesion, and wear. Aluminum (Al) substrates have been chemically reacted with perfluorodecanoic acid (PFDA ...

Single-molecule-level characterization of supramolecular systems at surfaces

Dietmar Payer

This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...
