Galvanic replacement reactions of Ga and In with Cu for the synthesis of bimetallic nanoparticles
The need for efficient and selective catalysts, capable of driving important conversions to build a more sustainable society, encourages the development of synthetic approaches towards new nanomaterials. Cu-based bimetallic nanoparticles (NPs) promise to f ...
EPFL2022Mapping Catalyst‐Solvent Interplay in Competing Carboamination/Cyclopropanation Reactions
Nicolai Cramer, Matthew Wodrich, Miyeon Chang, Simone Gallarati
Group 9 metals, in particular Rh III complexes with cyclopentadienyl ligands, are competent C–H activation catalysts. Recently, a Cp*Rh III catalyzed reaction of alkenes with N -enoxyphthalimides showed divergent outcome based on the solvent, with carboami ...
2022Chiral Diimine Complexes of Earth-Abundant Transition Metals for Asymmetric Catalysis
The application of Earth-abundant metals in asymmetric catalysis is key to transition towards a more sustainable chemistry. In particular, expanding the library of redox-active ligands capable of supporting Earth-abundant metals is essential in order to re ...

Andreas Mortensen, Yves Bellouard, Raphaël Charvet, Fatmah Ebrahim, Cyril Dénéréaz, Léa Deillon, Tao Yang, Enrico Casamenti, Luciano Borasi, Sacha Jérémy Florentin Pollonghini
Despite remarkable progress made in recent years, producing freeform three-dimensional micro-components out of copper, silver or gold and their alloys remains an engineering challenge: current processes are either too slow to be economically viable, or pro ...
2021Elemental and Thermo-gravimetric Characterization of Trace Metals in Leaves and Soils as Bioindicators of Pollution in Kyiv City
Christian Ludwig, Ajay Bhagwan Patil, Mohamed Tarik
In this study, leaf and soil samples were used as bio-monitors for different alkali and heavy metals at six different locations in Kyiv city. Using x–y plots of the inductively coupled plasma optical emission spectroscopy (ICP-OES) data measured the discre ...
2021High resolution meandering metal patterns enabled by nano-bridge stencil
Jürgen Brugger, Giovanni Boero, Yi-Chiang Sun
We present a new strategy for the fabrication of long meander-like metallic patterns based on the use of nano-bridges to stabilize fragile SiN stencils. Continuous metal traces are obtained by taking advantage of a controllable blurring effect introduced b ...
2021Activation of small molecules promoted by multimetallic complexes supported by redox active ligands
The activation of small molecule is a topic of high current interest. A variety of homogeneous end heterogeneous catalysts have been studied to be able to promote chemical transformation of industrial relevance under mild condition and therefore decrease t ...
EPFL2020Theory of double-kink nucleation in dilute BCC alloys
William Curtin, Alireza Ghafarollahi
Yielding in pure BCC metals and dilute substitutional alloys occurs by double-kink nucleation and propagation along screw dislocations. At low temperatures, the yield stress is controlled by double-kink nucleation. Here, an analytical statistical model is ...
