Luby Stefan

Is a senior researcher at the Institute of Physics, Slovak Academy of Sciences, and professor of physics at the Slovak University of Technology in Bratislava. He focused on semiconductors, thin films of metals, silicides and resistive material, trimming of resistors and reliability of integrated circuits at first. In the field of electromigration research he created a scientific school. Currently he deals with nanoscience and nanotechnology with a focus on nanoparticles, multilayers, graphene, supercrystals and applications of these structures in X-ray mirrors, gas-, vapor- and deformation sensors. He performed his research in Slovakia and at universities and research centres in Germany, Italy, USA, Japan and Greece. His publication activity includes more than 400 papers, 15 books and chapters, 9 patents and 18 books of the literature of the fact. He was supervisor of 40 PhD/CSc. and diploma works. He was awarded doctorates honoris causa, prizes and medals in Germany, Japan, Hungary and Czech Republic and Slovakia. HYDROGEN VS. GRAPHENE: SIMILARITIES AND PITFALLS IN THE APPLICATIONS OF TWO PROGRESSIVE MATERIALS S. Luby 1 , M. Lubyová 2 1 Institute of Physics SAS, Bratislava, Slovakia 2 Centre of Social and Psychological Sciences SAS, Bratislava, Slovakia BACKGROUND: 1st decade of 21st ct. brought us two important inventions. In 2004, monoatomic graphene flakes 0.34 nm thick with remarkable applications in material technology were exfoliated (Nobel prize 2010). In 2007, Ohta et al. drew attention to the healing effects of molecular hydrogen (H 2 ≈ 0.1 nm) reported already in more than 100 diseases. SIMILARITY: both substances are used in elementary form, which guarantees repeatable properties and interpretation of results in line with basic natural laws. Raw material resources are not limited and both elements belong to primary biogenic elements. Due to their small size, they easily penetrate cellular barriers. Based on these similarities, some experiences derived from graphene research are used here to inform hydrogen community. EXTRAPOLATIONS: • thanks to attractive properties and financial support, graphene has penetrated the field of sensors, composites, solar cells, batteries, etc. Similarly, H 2 penetrates many fields, including medicine, sports, agronomy, food conservation. It can be assumed that over time, H 2 applications might also receive systemic support at the EU level, analogous to the graphene flagship project. • In the area of graphene, we observe a huge publication boom based on multiplication of research, which is becoming too expensive. This is what the H 2 community should avoid. • Graphene was overhyped from the beginning (miraculous material, crown jewel, backbone of industry). In H 2 applications, metaphorical expressions also appear (miraculous substance, rising star). The result is a decrease in the trust of the public. • However, numerous communities are pushing for interdisciplinary research. We will present the case of H 2 monitoring using graphene gas sensors and hydrogen storage in defective graphene.
