Pulsed laser ablation in liquid is a very powerful technique that allows to synthesize colloidal solution of nanoparticles, starting from target and solvent, without waste. The performance this process terms ablated mass per time depends on the fluence, energy delivered unit (or effective) area. Experimentally fluence evaluation tedious indirect process, since optical path passes through lens an air–liquid interface, which not easy observe. In work, computational approach provides...
Hydrogen (HER) and Oxygen (OER) evolution reactions play a fundamental role in the field of green environmental sustainability, because they are key for water electrolysis. In this work copper (Cu) nanoparticles (NPs) produced by pulsed laser ablation liquid from target framework developing low-cost, earth abundant non-pollutant electrocatalyst. Various solvent energy fluence explored. Electrodes have been realized drop-casting Cu NPs onto Nickel foam (NF) substrate, with catalyst loading...
In the field of sustainability, hydrogen (H2) is considered a clean fuel and renewable energy source with no pollutant emissions. The production H2 by water electrolysis well-known among scientific community. Still, alkaline represents challenging process requires expensive materials have to be avoided in order lower impact production. This work deals copper (Cu) nickel (Ni) nanoparticles (NPs) as catalysts for splitting reactions. These NPs are synthesized using pulsed laser ablation liquid...
How nice would it be to obtain the size distribution of a nanoparticle dispersion fast and without electron microscope measurements? UV-Vis-NIR spectrophotometry offers very rapid solution; however, spectra interpretation can challenging needs take into account nanoparticles agglomeration. This work suggests Monte Carlo method for fitting using one or two distributions starting from dataset precomputed based on Mie theory. The proposed algorithm is tested copper produced with Pulsed Laser...
