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 ...
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 ...
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 ...
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 ...
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 ...
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 ...

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 ...
