The ability to design and fabricate advanced nanostructured materials is crucial for the development of emerging technologies in areas such as energy, optoelectronics, microelectronics, and sensing. Among the physical fabrication approaches, laser-based methodologies, particularly Pulsed laser Deposition (PLD), offer unique advantages in terms of flexibility, precision and material versatility, enabling the synthesis of a wide range of materials, from metals and oxides to structurally complex systems.
In this talk, I will present highlights of my research activities, focusing on the fabrication of nanostructured materials using PLD, and on the study of the optical properties of novel semiconducting systems based on ZnO, g-C3N4 etc. targeting to sensing applications.

Disordered systems subject to a fluctuating environment can self-organize into a complex history-dependent response, retaining a memory of the driving. In sheared amorphous solids, self-organization is established by the emergence of a persistent system of mechanical instabilities that can repeatedly be triggered by the driving, leading to a state of high mechanical reversibility. As a result, the response of the system becomes correlated with the dynamics of its environment. These correlations furnish a mechanism by which a system can sense and respond to its environment. They emerge across a wide variety of soft matter systems, suggesting that this form of self-organization is generic and hence may depend very little on the underlying specifics
In this talk I will first review self-organization in driven amorphous solids, and then turn to a discussion of what self-organization in driven disordered systems can teach us about how simple organisms lacking a brain, such as bacteria, can sense and adapt to their changing environment.

JOINT DEPT. OF CHEMISTRY AND IESL SEMINAR
Owing to their remarkable structural and photophysical properties—such as strong absorption and/or emission in the UV-vis and near-infrared (NIR) regions, excellent charge transport capabilities, and extensive chemical versatility—subphthalocyanines (SubPcs) have secured a prominent place among the most extensively studied and versatile porphyrinoid systems [1]. These aromatic macrocycles, distinguished by their unique non-planar geometry, demonstrate considerable potential for a wide range of advanced applications. These include the formation of polar superstructures, the development of thermotropic and lyotropic liquid crystals, and their use as non-fullerene acceptors. We will discuss how SubPcs can be employed in molecular photovoltaics [2], particularly as singlet fission materials [3], and examine the potential of their enantiopure derivatives [4] in chiral technologies [5]. Furthermore, we present the synthesis and characterization of SubPc-based columnar materials [2] and describe on-surface synthetic strategies for the construction of two-dimensional chiral polymers [4a].

Position Description
Structure, dynamics and rheology of biobased formulation and the viability of inserted microbes.
The 36 months PhD research project is located in the Polymer and Colloid Science lab in FORTH-IESL and is part of the BIOMAC-BP MSCA Doctoral Network aiming to optimize dispersing medium for microbes to be delivered to plants. In this experimental soft matter project, we will characterize the properties of the selected multiphase materials. Precise systems and preparation protocols will be selected in close collaboration with BIOMAC-BP partners. Typical systems consist of foams or emulsions stabilized by biobased nanocrystals (like starch or cellulose). The characterization of the microscopic structure will be done using combination of scattering and microscopies. Rheological properties will be measured. The mutual influence of the medium properties and of the microbe load will be studied in collaboration with UoC microbiologists.

12Position Description
The main aim of INERRANT is to drive genuine advancements for safe-and-sustainable-by-design materials, to ensure the economical and widespread utilization of safer LIBs in modern society. To realize this, INERRANT is formulating a holistic approach to enhance safety, boost performance and improve fast charging, of Gen 3 LIBs tailored for mobility applications. The pivotal S&T challenges encompass: development of functional materials, design sustainable fabrication and recycling processes and understanding of pertinent interfacial phenomena and degradation mechanisms. Specifically, INERRANT aims to pioneer: (i) innovative (nano)materials combinations for anodes and cathodes; (ii) nanofiber-based architectures for smart-functioning separators able to protect battery flaws; (iii) stimuli responsive electrolyte formulations designed for rapid reactions against external disturbances and mitigate degradation processes at the cathode; (iv) cutting-edge and eco-friendly recycling processes to improve the purity of recovered materials from end-of-life LIBs.
One of the objectives of the project is to develop novel electrolyte formulations to enhance battery safety and performance by improving the impact resistance and mitigate degradation of cathode materials. One of the main directions towards this goal is via the development of safe impact resistant electrolytes that possess a discontinuous shear thickening behavior at low particle concentration. The mechanical response of Gen 3 LIB electrolytes with various additives, will be explored to achieve optimal shear thickening (ST), maintaining or improving electrical conductivity of the composite electrolyte.
Within this framework the selected candidate will explore the rheological properties of complex composite suspensions and yield stress fluids with varying colloidal shapes (sphere, rods, platelets) and interactions, aiming to design impact resistant electrolytes for Li-ion Batteries. Our research plan will include a combination of state-of-the-art rheometry and imaging/microscopy and/or scattering probes (such as rheo-confocal microscopy and light scattering under shear). These will enable us to unravel links between rheological properties with microstructure and particle dynamics. Rheological measurements will also be complemented with in-situ conductivity measurements that will allow further fine-tuning structure and mechanical properties in conjunction with electric properties of the electrolyte suspension
