Nanoelectronics – the highlight of the NANOCON´21 conference

The XIII. international conference NANOCON took place in Brno on October 20 – 22, 2021. In total 280 participants from 19 countries listened 84 lectures and could see 150 posters. Their common theme was nanomaterials and the latest advances in their research and applications. In the Czech Republic, it is the largest event of its kind, and one of the largest in the Central European region. After a one-year break caused by the coronavirus pandemic, it could take place in the traditional format this year.

Professor Yury Gogotsi, director of the Drexel Nanomaterials Institute at the Drexel University in Philadelphia (U.S.A.) and currently one of the most world renowned materials scientists, opened the conference with his overview and, to some extent, futuristic lecture. He gave an insight into the world of 2D carbides and nitrides. Thanks to the attractive properties of these nanomaterials (mainly high electronic conductivity and outstanding electromagnetic interference shielding), their promising use in telecommunications, energy or medical and electronic devices is expected.

Nanotechnologies and nanomaterials in electronics was the highlight topic of the NANOCON´21. The reason is obvious. Current society is increasingly dependent on mobile devices, massive quantities of data need to be stored and analyzed, the semiconductor industry is significant driver in the global economy, and high-performance computing supports human actions in science, technology, engineering, medicine, industry and in daily life. 

The topic of nanoelectronics resonated in practically all thematic program sections of the NANOCON´21 and also in two plenary lectures. Professor Dieter H. Bimberg from the Technical University of Berlin and the Executive Director of the Chinese-German Center for Green Photonics at Changchun presented the results of his research relating to a novel quantum dot based electronic memories and their advantages, especially long storage times, short write, read and erase time. Professor Tomáš Jungwirth from the Institute of Physics of the CAS in Prague presented excellent discoveries of his team in the field of antiferromagnetic crystals enabling to store electronic data much faster than ever before.

However, the thematic scope of the conference lectures was traditionally much broader. In Brno researchers presented their R&D in the preparation, characterization of the properties of nanomaterials and their applications in various sectors, including medicine and the environment. Monitoring and potential toxicity of nanomaterials, as well as their impact on health and the environment were also discussed. Special attention in this direction raised the lecture of Prof. Tomáš Cajthaml from the Faculty of Science, Charles University in Prague, focused on toxicity of microplastics. He presented the results of studies confirming that fish living in the sea and other water sources intensively accumulate small plastic particles (of diameter 1 µ and less) in various organs which significantly burden their organism. And because they are mostly hydrophobic, they cannot be easily removed from the body.

The prize for the best poster has been awarded to Rodrigo Ferreira from the Institute of Physics of the CAS. The young scientist in his work presented the results of his study of optoelectronic properties of single-molecule emitters and their aggregates and indicated also the possibilities of their promising use for the development of quantum computers and molecular storage devices and sensors.

Two Best Lectures for the Young scientists (up to 33 years of age) has been awarded. The PhD student Hadi Hematian from the Faculty of Electrical Engineering of the Czech Technical University in Prague won the award for his talk relating to the use of zinc oxide as a semiconductor in biomedical and pharmaceutical applications. Jiří Doležal from the Faculty of Mathematics and Physics of Charles University in Prague received the prize for a lecture presenting a developed and easily applicable procedure for effective compensation of high-frequency lines and for determining the size of the transmission function in the GHz band. In the contest named after Dr. Tasilo Prnka – a major promoter of nanotechnology in the Czech Republic, a record number of 34 competitors participated.

The next, 14th NANOCON conference will take place on October 19 – 21, 2022. It will accentuate the latest scientific and technological challenges in nanomedicine. More information can be found at www.nanocon.eu

Abstract: This contribution is focused on utilization of a sequential chemical fractionation method for determination of organic matter content, its distribution in biochar and the possible use of biochar as a soil conditioner in agriculture. For these purposes the optimized chemical fractionation procedure was used to reveal the content of organic matter in different biochar samples with different properties (samples with European biochar certification for usage in agriculture) which depend significantly on the temperature used during a pyrolysis of biomass residues in the process of biochar production.

Abstract: It is already known, that porphyrin–bases are offering better protection against steel corrosion than metalloporphyrins due to their ability to form very stable metallic complexes by linking in their inner core the iron contained in different steels. In this respect, 5-(4-carboxy-phenyl)-10,15,20-tris-(4-phenoxy-phenyl)-porphyrin was synthesized by multicomponent Adler-Longo synthesis, using two different aldehydes and pyrrole, characterized to certify the structure and further used for formulating double thin layers in all possible combinations with MnTa2O6.

Abstract: In recent years the study of mechanical properties using atomic force microscopy (AFM) has become very popular. As it uses much lower forces than nanoindentation methods it allows to focus on smaller volumes which makes it an excellent tool for the study of thin films and the creation of high-resolution maps.
