Investigation of femtosecond laser-enabled 3D micro-infiltration processes
In the last decades, the femtosecond laser micromachining of glass has attracted a lot of attention due to its three-dimensional manufacturing ability and flexibility both in terms of compatible substrates and modification types. Yet, to fully unravel its ...
EPFL2022Galvanic 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 ...
EPFL2022Theory-guided design of high-strength, high-melting point, ductile, low-density, single-phase BCC high entropy alloys
William Curtin, Christian Leinenbach, Carolina Baruffi, You Rao
The search for new high-temperature alloys that can enable higher-efficiency/lower-emissions power generation has accelerated with the discovery of body-centered cubic (bcc) refractory High Entropy Alloys (HEAs). These many-component, non-dilute alloys in ...
PERGAMON-ELSEVIER SCIENCE LTD2022Intrinsic luminescence blinking from plasmonic nanojunctions
Tobias Kippenberg, Christophe Marcel Georges Galland, Giulia Tagliabue, Magalí Alejandra Lingenfelder, Sachin Suresh Verlekar, Wen Chen, Karla Banjac, Aqeel Ahmed, Philippe Andreas Rölli
Plasmonic nanojunctions, consisting of adjacent metal structures with nanometre gaps, can support localised plasmon resonances that boost light matter interactions and concentrate electromagnetic fields at the nanoscale. In this regime, the optical respons ...
2021Anchoring single platinum atoms onto nickel nanoparticles affords highly selective catalysts for lignin conversion
Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Antoine Philippe Van Muyden, Lu Chen, Ulf Anders Hagfeldt, Jun Li, Lichen Bai, Linfeng Pan, Yun Tong
Due to the highly complex polyphenolic structure of lignin, depolymerization without a prior chemical treatment is challenging, and new catalysts are required. Atomically dispersed catalysts are able to maximize the atomic efficiency of noble metals, simul ...
ELSEVIER2021Noble Metal Nanoparticles Stabilized by Hyper-Cross-Linked Polystyrene as Effective Catalysts in Hydrogenation of Arenes
This work is addressing the arenes' hydrogenation-the processes of high importance for petrochemical, chemical and pharmaceutical industries. Noble metal (Pd, Pt, Ru) nanoparticles (NPs) stabilized in hyper-cross-linked polystyrene (HPS) were shown to be a ...
2021Photonic Flash Synthesis of Mo2C/Graphene Electrocatalyst for the Hydrogen Evolution Reaction
Hubert Girault, Danick Reynard, Bhawna Nagar
Nowadays, molybdenum carbides (Mo2C) represent alternative electrocatalysts to noble metal for the hydrogen evolution reaction (HER). Here, a fast and simple process is proposed for the fabrication of Mo2C-based electrocatalysts on a carbon cloth substrate ...
AMER CHEMICAL SOC2021High 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 ...
EPFL2020Colloidal copper-based nanocrystals: synthesis and mechanistic studies.
The growing interest in nanotechnology stems from its promise of developing new materials and devices by taking advantage of unique phenomena emerging at the nanoscale. In this size regime, parameters like size and shape strongly impact the physico-chemica ...
