Abstract
Since the discovery of catalysis, the identification of the different species in the mechanism involved in the reaction has been a challenge. When nanocatalysis entered the scene, the detection of material that came out from solutions attracted the attention and raised several questions: was this solid part of the nanocatalyst? was it the precursor of the nanocatalysts (the so-called precatalyst)? or was it the nanocatalyst itself? The discussion focuses on whether the catalysis is determined by the species that exist in solution or if it is generated from the support and hence the catalytic reaction is carried out with these soluble species. Furthermore, it appears that leaching is a phenomenon which occurs mainly in palladium- catalyzed reactions and that involves palladium nanoparticles (NPs). The research, findings and patents in the leaching process in catalytic reactions are reviewed in the present paper.

Advances in Vanadium and Titanium Resources for High-performance Materials via Nanostructuring and Nanoengineering (updated BMS-NANOTEC-2023-HT-31)
Vanadium and titanium-based materials are ideal candidates for structural and functional materials in aerospace, biomedical engineering, optics, catalysis, energy storage and conversion etc. Vanadium/titanium-based alloys, compounds and materials have a large family with different chemical compositions, dimensions, structures/morphologies, and chemical/physical/mechanical properties, which provides huge opportunities for the development of emerging ...read more
Green Nanotechnology and Nanomaterials for a Sustainable Environment
Green nanotechnology (GN) might wind up being the most efficient platform for achieving the goals of the 2030 Agenda. The goal of GN is to create goods and procedures that are secure, energy-efficient, waste-free, and emit fewer greenhouse gases. Such goods and procedures use renewable resources, and/or their environmental impact ...read more
Nano-coatings and Nanoscale Composites for Hazardous Environments
Automobile, defence, and aerospace sectors need lightweight material for fuel efficiency and lower emissions. Often these materials are added with nanoscale reinforcements or have to be coated with nanomaterials to improve the scratch resistance, self-healing behaviour and corrosion and wear resistance and are all much needed for hazardous environments without ...read more
NANOSTRUCTURED NEUROMORPHIC DEVICES: TOWARDS IN MATERIA COMPUTING
The efforts pursued in the last decade to build up brain-inspired systems with electronic hardware solutions to solve complex data processing tasks, have leaded to the development of a new generation of devices, as memristor crossbar arrays, and their different applications became more and more reliable. One of the basic ...read more
