Asta Tamulevičienė (Lithuanian SME Partner Nanoversa) completed a full-time secondment at Aveiro University (UAvr), under supervisor Nikolai Sobolev, from 2026-06-27 to 2026-07-13, under Work Package 1, Task 1.2. The secondment focused on an initial assessment of ZnO tetrapod network (TN) functionalization methods and their impact on material properties, serving as an initial training and knowledge-building stage for subsequent experimental and functionalization work.
During the secondment, the researcher gained an initial understanding of ZnO nanostructure functionalization using molecular coatings and nanoparticles, and explored nanoparticle-based approaches for tuning electronic, chemical, and UV-sensitive material properties. She observed and analysed nanoparticle self-assembly and deposition methods used in functionalization processes, and reviewed the relationships between functionalization methods and resulting material properties in ZnO tetrapod networks. The stay also included participation in internal meetings and technical discussions with host institution researchers, along with knowledge exchange sessions on functionalization strategies and their applicability to neuromorphic systems, including in-sensor signal processing.
Training received covered ZnO nanostructure functionalization techniques using molecular coatings and nanoparticles, nanoparticle self-assembly and surface modification methods, linking functionalization approaches to material properties and device-relevant performance, and an introduction to neuromorphic application concepts related to functional materials.
As a result, the researcher acquired foundational knowledge of ZnO TN functionalization strategies, identified key nanoparticle-based approaches for tuning material properties, and developed an understanding of functionalization-property relationships relevant to neuromorphic applications, while assessing the potential of functionalized ZnO TNs for such systems. These outcomes align with the purpose of the secondment – building initial competence in functionalization approaches to support further experimental and application-oriented work within Task 1.2. For the project, this strengthens the knowledge base on functionalization strategies within WP1, supports development of tunable ZnO TN systems for neuromorphic applications, facilitates future experimental collaboration between partners, and contributes to linking material functionalization with device-level performance.
