laser pulses to “clone” gold nanoparticles

Researchers and students from the Institute of Nuclear Fusion at UPM participate in a paper published in the journal Science, which shows that a solution with nanorods modified by ultrashort laser pulses has an optical quality never seen before.

Researchers and students from Universidad Politécnica de Madrid (UPM) / Institute of Nuclear Fusion, located in the Higher Technical School of Industrial Engineers, participate in a study that reports the use of ultra-short laser pulses to mold gold nanorods in aqueous solution. The work shows that the solution with the modified particles has an optical quality never seen before. The study was published on November 3rd, 2017 in the journal Science.

Forst meeting Towards Understanding and Modelling Intense Electronic Excitation

The First General Meeting of the COST Action CA17126 was held at Escuela Técnica Superior de Ingenieros Industriales (ETSII) belonging to Universidad Politécnica de Madrid on the 19th and 20th of November 2018.

The Action was approved on April 2018, the first Management meeting took place on September 12 and will run until September 2022. Researchers from twenty-five countries have joined the Action so far, constituting a very multidisciplinary network interested in different phenomena, effects and applications related to electronic excitation.

Together with groups from Mexico, Argentina and the Autonomous University of Madrid, we have just published in the journal Scientific Reports a study leaded by Dr. Ovidio Peña Rodríguez. The paper, entitled Understanding the ion-induced elongation of silver nanoparticles embedded in silica, we have studied the elongation of silver nanoparticles irradiated with swift heavy ions. The localized surface plasmon resonance of silver nanoparticles has a strong dependence on the particle shape and size, which allowed us to obtain the geometrical parameters with remarkable accuracy by means of a fit of the optical spectra.

Eduardo Oliva, Marie Sklodowska-Curie Fellow of the Instituto de Fusión Nuclear has attended to the 66th Lindau Nobel Laureate Meeting. He has been one of the only 16 MSC fellows and one of the only 11 Spaniards to be selected by the Council to attend. Once every year, 30 to 40 Nobel Laureates convene at Lindau to meet the next generation of leading scientists: undergraduates, PhD students, and post-doc researchers from all over the world.

Current trends in the automotive industry to improve engine efficiency such as down-sizing, start stop engines, turbo-charging and the use of lower viscosity oils demand new coatings to withstand higher temperatures and higher loading densities on components.

DIMMAT 1

High-performance racing car piston coated with DLC

Diamond-like carbon (DLC) coatings are the best-suited solution to enhance engine efficiency. However, poor adhesion is of particular concern for in-service operation. DIMMAT project aims to develop novel High Power Impulse Magnetron Sputtering to solve adhesion issues of DLC coatings.

Highly ionized metal flux generated with HiPIMS allows to efficiently remove contaminants of the surface and to incorporate metals into the substrate. By promoting metallic bonding in the coating-substrate interface, the work of adhesion is increased and the detachment of coatings is prevented.
