European Research Institute
During the week of the 16 th March 2026 took place the EUT + Week at Troyes. The EUT + is the European University of Technology which is an alliance formed of 9 european universities: the Hochschule Darmstadt, University of Applied Sciences( Germany), Rīgas Tehniskā universitāte( Latvia), Technological University of Dublin( Ireland), Technical University of Sofia( Bulgaria), Cyprus University of Technology( Cyprus), Universidad Politécnica de Cartagena( Spain), Universitatea Tehnică din Cluj- Napoca( Roumania), Università degli studi di Cassino e del Lazio Meridionale( Italy) and the Université de technologie de Troyes( France) which is the coordinating university of this alliance. The EUT + is getting structured to become a unique, single university with 9 different sites and within this structuration, research also needs to be structured. The alliance thus created a new‘ tool’ for doing research at the EU level via a European Research Institute or ERI. More specifically, the ERI EUTINN, for the EUT + Institute of Nanomaterials & Nanotechnologies, has been officially recognised by the EUT + in 2025. This new model for a future European research is based on 6 Research Streams: Nanomaterials, Nanotechnologies and sensors, Nanotechnologies for communication and information technologies, Nanotechnologies for energy applications, Nanomedicine & nanobiology, Nanomaterials & nanotechnologies: toxicology, pollution, food and agriculture. The NANO- PHOT graduate school is fully involved. More info here: https:// www. univ-tech. eu / eutinn

MICROGRAPH AWARD 2026
Currently third-year PhD student within the NANOPHOT graduate school, Antoine Dussard is carrying out his CIFRE thesis between the Université de Technologie de Troyes at the laboratory L2n( Light, nanomaterials, nanotechnologies- UTT) and the company SURYS( IN GROUPE) within the framework of the joint laboratory In-Fine( Innovation center for industrial nanostructured foils), which focuses on the fabrication of large-scale nanostructures. Antoine had the opportunity to participate and win one of the prizes of the“ Micrograph Award 2026” organized each year by the company Raith, a world leader in maskless nanofabrication systems. Antoine ' s thesis focuses on the development of largescale 2.5D electron beam lithography, consisting in the fabrication of hierarchical structures over several square centimeters by electron beam lithography for the production of structural colors. Structural colors are generated by different physical mechanisms such as diffraction, resonance phenomena, cavities, waveguides, etc. Hierarchical structures( nanostructures on microstructures) make it possible to create colored animations, where the microstructures can selectively redirect the incident light which is colored thanks to the nanostructures. These effects can be observed in specular reflection, diffuse reflection or transmission. The awarded design consists of a Tulip pattern, 5 cm high and 1.6 cm wide, fabricated using a Raith eLINE electron beam lithography system. This tulip is composed of structures producing structural colors, without the use of pigments. These patterns make it possible to obtain a first color in diffuse reflection, as well as a second one in specular reflection. The elementary structure consists of a Fabry – Perot cavity, in which a fine control of the depth and the refractive index makes it possible to modify the optical path difference between the different interfaces, and consequently the interferometric conditions and the resulting colors.
