Decennial Awards on Advanced Nanoparticle Generation & Excitation by Lasers in Liquids (ANGEL)

On the occasion of the 10th anniversary, the ANGEL conference Program Committee and International Advisory Board (http://angel-conference.org/) are proud to present the “ANGEL Decennial Award” selection to celebrate all those people who contributed to the success of the field of Advanced Nanoparticle Generation and Excitation by Lasers in Liquids. After serious selection, so honorable to announce the winners as follows:


There are three award categories:

Award 1: ANGEL Decennial Award for Best Image - The best image related to ANGEL research.

Winner 1: Torres Mendieta Rafael Omar

Technical University of Liberec, Institute for Nanomaterials, Czech Republic




Artwork representing the Coulomb explosion of a nanoparticle in a solution, a phenomenon that is closely related to the most iconic phrase of Richard P. Feynman “There’s plenty of room at the bottom”. As discovered by the end of the last century by Prochazka and co-workers, the laser irradiation of nanomaterials immersed in liquids enables the ejection of their constituent electrons. The continuous electronic ejection leaves an excessively ionized system that finally surpasses the nanomaterial’s cohesive energy ending up in its fragmentation. The finding of this phenomenon, therefore, unveiled a neat alternative to keep finding room at the bottom.


Winner 2: Ziefuss Anna Rosa

University Duisburg-Essen, Technical Chemistry 1, Germany



Artistic visualization of the laser fragmentation in liquids process – a process that takes place on ultra-short time scales. Coherent light can trigger a series of processes in metallic nanoparticles (NPs), which, if the energy input is sufficient, leads to downsizing of the metallic spheres. By appropriate variation of the energy deposition kinetics, the driving force for fragmentation, and the colloidal environment, a wide range of particle sizes can be adjusted. Fully inorganic gold nanoclusters (NP < 3 nm) are particularly interesting. They represent a completely new kind of matter and show a pronounced fluorescence instead of a plasmonic behavior.


Award 2: ANGEL Decennial Publication Award - Innovative research article related to ANGEL topic.

Nominator: Sven Reichenberger

University Duisburg-Essen, Technical Chemistry 1, Germany

Nominee:

Article: Atomistic modeling of nanoparticle generation in short pulse laser ablation of thin metal films in water (https://doi.org/10.1016/j.jcis.2016.10.029)

Authors: Cheng-Yu Shih, Chengping Wu, Maxim V. Shugaev, Leonid V. Zhigilei

Affilication: Department of Materials Science and Engineering, University of Virginia, 395 McCormick Road, Charlottesville, VA 22904-4745, USA

To understand the thermodynamic and kinetic processes occurring on ultrashort timescales during pulsed laser ablation is one of the, if not the biggest scientific question in current research of laser-based nanoparticle synthesis. Within the nominated article, the group of Leonid Zhigilei provided first mechanistic insight into the dynamics of the plasma plume, the related initial stages, and kinetics of particle nucleation and growth, thereby describing the origin of the bimodality often observed by laser ablation in liquids. The paper strongly inspired this research field and led to a new perspective on the limitations and possibilities for laser-based synthesis of nanomaterials.


Award 3: ANGEL Decennial Big Challenge Award - The next biggest challenge or imagined advance in the field of ANGEL research or application.

Winner 1: Coviello Vito

University of Padua, Department of Chemical Sciences, Italy

Challenge: Laser Ablation of Alloys

An important challenge for ANGEL could be the synthesis of nanoalloys with a specific composition. The generation of bimetallic nanoparticles (NPs) by laser ablation in liquid (LAL) is well established and is an important strength of LAL. Despite this, to date is impossible to control or drive the synthesis toward a specific NPs composition. This would make the technique even more promising and interesting.

Winner 2: Zhilnikova Margarita

Prokhorov General Physics Institute of the Russian Academy of Sciences and Moscow Institute of Physics and Technology, Russia

Challenge: Laser ablation of metals in salts melts

Salts melts is unexplored liquids as medium for laser ablation of metals and other solids. The main problem of ablation of metals such Al, Ti etc. in aqueous solutions is oxidation of generated nanoparticles. The environment in the form of salts melts helps to avoid this phenomenon. Our team has already realized the ablation of some targets (Au, Cu, Al) in salts melts (NaNO3, NaNO2, LiNO3) at temperature 300-350 °C. The choice these salts was related to their low melting temperatures. We obtained unusual nanocomposites of salts with nanoparticles. In other words, salts melts represent new interesting liquid medium that may be used in laser ablation of solids and eventually lead to generation of nanoparticles with completely new properties compared to well-known liquids.

Congratulations to the winners!Thank you all for your kind participation!
