Direct amidation of esters with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Esters are one of the most common functional groups in natural and synthetic products, and the one-step conversion of the ester group into other functional groups is an attractive strategy in organic synthesis. Direct amidation of esters is particularly ap ...

Mechanical signatures of degradation of the photovoltaic perovskite CH3NH3PbI3 upon water vapor exposure

László Forró, Endre Horvath, Wanda Andreoni, Bálint Náfrádi, Massimo Spina, Ayat Karimi

We report on the mechanical properties of CH3NH3PbI3 photovoltaic perovskite measured by nanoindentation. The Young's modulus (E) of the pristine sample is 20.0 +/- 1.5GPa, while the hardness (H) is 1.0 +/- 0.1GPa. Upon extended exposure to water vapor, bo ...

Multi Seasonal Functional Group Analysis by FT-IR Spectroscopy of Atmospheric Aerosol in Zurich

Satoshi Takahama, Matteo Reggente

Atmospheric particulate matter (PM) has been associated with increased morbidity and mortality, reduced visibility, and is one of the least understood components of the climate system. Organic matter (OM) constitutes a substantial fraction (up to 80%) of P ...

Strong Improvement of Long-Term Chemical and Thermal Stability of Plasmonic Silver Nanoantennas and Films

Olivier Martin, Christian Santschi, Xiaolong Wang

Silver (Ag) nanostructures and thin films are advantageous plasmonic materials as they have significantly lower losses than gold (Au). Unfortunately, Ag nanostructures suffer from poor chemical and thermal stability, which limit their applications. Here, t ...

On Decoupling Chemical Reaction Systems

Sriniketh Srinivasan

Chemical reaction systems act as the basis to get the desired products from raw materials. An in-depth understanding of all the underlying rate processes is necessary for monitoring, control and optimization of chemical reaction systems. Traditional repres ...

Deguelin exerts potent nematocidal activity via the mitochondrial respiratory chain

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Abdul Jabbar

As a result of limited classes of anthelmintics and an over-reliance on chemical control, there is a great need to discover new compounds to combat drug resistance in parasitic nematodes. Here, we show that deguelin, a plant-derived rotenoid, selectively a ...
