We are very happy that the traditional annual get together of the Physics Department is back, and that we can discuss science and education face-to-face with our colleagues and friends! The Day of the Physics Department (Día del DF, DDF) is a great meeting where professors, researchers, graduate and undergraduate students discuss the [...]
By nature, photon emission occurs without directionality. In most situations photon emission is dipolar, and multipolar emission may be obtained under very special conditions. Therefore, imposing directionality requires the mediation of specific devices. Directional optical nano antennas have been demonstrated over a decade ago using the Yagi-Uda concept; i.e. a phased array that produces constructive [...]
The iCANX talks is a wonderful initiative by Prof. Haixia (Alice) Zhang from Pekin University. Every Friday a new talk by top scientists from around the world. You can check them out here https://ican-x.com/talks This friday, it was the turn of Oscar Martinez, former Professor of the Physics Department, currently at the Faculty of Engineering [...]
Prof. Jochen Feldmann has been a great scientist and mentor for many younger researchers. On the occasion of his 60th birthday, several of his mentorees and collaborators have contributed to a special issue of Advances Optical Materials in his honor. Happy birthday Jochen!!! Advanced Optical Materiales - Special Issue Photonics and Optoelectronics of [...]
During two weeks of June, Prof. Stefani visited our close collaborator Prof. Guillermo Acuna at the University of Fribourg, Switzerland, where several former members of our group are currently working, like Dr. Mariano Barella and Ph.D. candidate Germán Chiarelli. Prof. Stefani gave lectures on the recent advances of our lab, and supervised projects in [...]
Fluorescence microscopy is a major workhorse in life sciences, biophysics, and physical chemistry, as it allows visualization with great specificity and sensitivity. In particular, the detection of single fluorescent molecules has been used to provide information beyond ensemble averages with applications in different fields of research. For example, super-resolution methods based on the localization of [...]
The morphology and composition of metallic nanoparticles (NPs) determine their optical response, so finely controlling them at the single particle level is a key to achieve tailored functionalities. In a recent publication by Luciana Martinez et al. we show that the plasmon-driven growth of Au NPs can be monitored in real time through photoluminescence measurements. [...]
Today, Cecilia "Chechu" Zaza defended her Ph. D. thesis “Impresión óptica de nanopartículas de silicio y métodos para medir temperatura con resolución espacial en la nanoescala”, obtaining the highest grade from the jury Dr. Gustavo Grinblat, Dr. Ana Sol Peinetti, and Dr. Ana María Huergo. Chechu joined the group in 2017 to work on her [...]
Starting in March 2022, Dr. Piotr Zdankowski has joined our group for a postdoctoral stay with a Research Fellowship of the National Agency for Scientific Exchange of Poland. The Research Fellowship programme aims to implement the Projects together with eminent foreign scientists and scientific teams as well as establish long-term relationship with foreign scientific teams. [...]
Founding Director of CIBION Prof. Dr. Pedro Aramendía has retired after 10 years leading the activities of the institute. Pedro has been a great researcher, teacher, and mentor of many young researchers. Thank you Pedro for all your work and [...]
