Interrupted Polonovski Strategy for the Synthesis of Functionalized Amino Acids and Peptides

Jérôme Waser, Emmanuelle Madeline Dominique Allouche, Christine Alice Jacqueline Marty

The alpha-functionalization of carbamate-protected hydroxylamine glycine derivatives, acting as imine surrogates via an interrupted Polonovski reaction, is described to access functionalized amino acid derivatives. The addition of C, N, O, and S nucleophil ...

Paediatric Personalized Research Network Switzerland (SwissPedHealth): a joint paediatric national data stream

Jacques Fellay, Dylan Lawless, Mariam Ait Oumelloul, Simon Christian J Boutry

Introduction Children represent a large and vulnerable patient group. However, the evidence base for most paediatric diagnostic and therapeutic procedures remains limited or is often inferred from adults. There is an urgency to improve paediatric healthcar ...

Life cycle assessment of power-to-gas applications via co-electrolysis of CO2 and H2O

Ligang Wang

Solid-oxide electrolysis technology (SOEC) can efficiently convert electricity from renewable sources into H-2 via steam electrolysis, or syngas (a mixture of H-2 and CO2) via co-electrolysis of steam and CO2. Co-SOEC provides the advantage of better therm ...

Frequency selection in a gravitationally stretched capillary jet in the jetting regime

François Gallaire, Isha Shukla

A capillary jet falling under the effect of gravity continuously stretches while thinning downstream. We report here the effect of external periodic forcing on such a spatially varying jet in the jetting regime. Surprisingly, the optimal forcing frequency ...

Storing Renewable Energy in the Hydrogen Cycle

Andreas Züttel, Elsa Callini, Shunsuke Kato

An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydroge ...
