Title: Novel sensing and actuating optical fiber devices

Place: A. Payatakes Seminar Room

Date: 10/07/2018
Time: 16:00 (coffee & cookies at 15:45)

Abstract:
In a world with steadily increasing energy demands, miniaturization and optimization of energy efficiency is becoming a key design element of devices. Optical fibers have proven excellent platforms for the realization of miniature, flexible and energy efficient sensors and actuators. In this work we present two different classes of optical fiber based devices: First, a miniature magnetic field sensor with field amplitude and direction sensing capability, realized by encapsulating ferrofluids on a D-shaped optical fiber. The total footprint of this sensor is of the order of a few hundred micrometers with possible applications in magneto-optical switching or sensing. Second, a novel-photonic bandgap optical fiber is presented, which was realized by infiltrating 2-methyl 4-nitroaniline (MNA) in the capillaries of a commercially available microstructured optical fiber. The resulting composite fiber exhibits a wavelength dependent guidance mechanism and second harmonic generation, both of which depend on MNA solidification inside the fiber capillaries. Post processing the composite fiber by means of thermal annealing and poling is used to alter the structure of the MNA material in the capillaries which affects both fiber transmittance characteristics and second harmonic generation efficiency. Such a type of optical fiber could be used in all-optical gating and wavelength conversion devices.

Title: Simulation of transport and reaction processes

Place: “Stelios Orphanoudakis” Seminar Room

 

Date: 03/07/2018
Time: 16:00 (coffee & cookies at 15:45)

Abstract: Aided by modern hardware and software advances, state-of-the-art computational techniques and virtual reconstructions have emerged recently as essential tools for the design of novel or improved materials, and for the discovery of innovated or enhanced properties of existing ones, successively corroborated by experimentation. Candidates for components with enhanced properties and processes with elevated performances are often suggested, designed and screened through simulations, even ahead or in place of usually strenuous and costly synthesis and characterization experiments. Extensive knowledge of key aspects and mechanisms of the flow, transport, sorption and separation phenomena in the interior of membranes on micro- and nanoscales is able to provide valuable insights on a significant number of processes related to porous membranes, and facilitate membrane design and optimization. Recent studies have shown that the efficiency of modern hemodialysis processes is controlled by module geometry, membrane properties, and operating conditions. Optimization of membrane performance usually requires extensive and laborious experimentation. Detailed mathematical models are often necessary to predict the performance of hemodialysis operation under various operational conditions at more affordable accuracy and time scales. The primary purpose of this line of work is to develop detailed models that will predict the removal of blood toxins during hemodialysis using multi-layered mixed matrix membranes. The modeling and simulation background of relevant membrane separation processes will be presented, and focus will be placed on the computer-aided reconstruction of porous membranes for controlled transport and separation of biological fluids, along with the development of models and algorithms for the simulation of protein-bound toxin dissociation, transport, and sorption phenomena in digitized porous membranes either impregnated with sorbents or coupled with living cells for blood purification.

Title: Development of Polymeric Membranes for water purification

Place: A. Payatakes Seminar Room

Date: 12/06/2018
Time: 16:00 (coffee & cookies at 15:45)

Abstract: Water pollution is one of the most critical global challenges in the modern era. The need for an adequate supply of clean water has led to new emerging technologies. Due to its energy-saving and cost-effective features, membrane technology has become the most effective platform for water purification, including seawater as well as municipal or industrial wastewater treatment. Among them, organic polymeric membranes possess several advantages against inorganic membranes. In the present work, polymeric membranes based on a polysulfone-based polymeric matrix were successfully prepared via non-solvent induced phase separation (NIPS) method.

The polysulfonetype polymer poly[2-(4-(diphenylsulfonyl)phenoxy)-6-(4-phenoxy)pyridine] (PDSPP) was used as the hydrophobic matrix and combined with its sulfonated derivative (SPDSPP) and a polymeric porogen in order to enhance the hydrophilicity and increase the porosity of the overall membrane system. The variables tested included PDSPP/SPDSPP/porogen w/w composition, type of porogen, type of solvent, type and temperature of nonsolvent, etc. Scanning Electron Miscroscopy (SEM), Scanning Electron Miscroscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Water Uptake % (WU %), Porosity %, Pure Water Flux (PWF), Pure Water Permeability (PWP), Attenuated Total Reflectance-Infrared Spectroscopy (ATR-IR) and Thermogravimetric Analysis (TGA) were the driving procedures and techniques used to evaluate the impact of the different parameters. The results shown that using different conditions the morphology of the membranes can be altered and therefore optimized, making them ideal candidates for water purification membranes.

Title: High Performance Solid Polymer Electrolytes for Energy Storage via Macromolecular Engineering

Place: A. Payatakes Seminar Room

Date: 05/06/2018
Time: 16:00 (coffee & cookies at 15:45)

Abstract: Climate change, pollution and declining fossil resources are overwhelming challenges to humankind. Gaseous emission from burning fossil fuels pollutes the air in large modern cities creating a global warming with alarming climate changes. These concerns have led to national initiatives to reconsider the use of alternative energy sources such as solar radiation, wind, and waves. However, the intermittence of these resources (their variability in time and wide distribution in space) requires high energy storage systems. To this end, secondary batteries based on lithium metal anodes are the most sought-after candidates for next-generation storage systems since they can store a large amount of energy per unit mass or volume. However, unstable electrodeposition and uncontrolled interfacial reactions occurring in conventional liquid electrolytes cause unsatisfying cell performance and major safety concerns.

Solid polymer electrolytes (SPEs) could be a “real game-changer” as they hold the promise to solve most of the problems of liquid electrolytes. SPEs are inherently safe, nonflammable and compatible with lithium metal anodes. Despite the considerable research effort in SPEs, the primary challenge is the development of solid materials with good mechanical properties without sacrificing ionic-conductivity. In this talk, the use of novel polymer nanostructured nanoparticles will be introduced as additives to liquid electrolytes for the synthesis of SPEs that exhibit an unprecedented combination of high modulus and ionic conductivity. The nanoparticles are composed of high functionality mikto-arm star copolymers in which stiff insulating arms complement ion conducting arms. Because of their molecular design and their colloid-like structure, the materials constitute the first example of allpolymer nanostructured materials where each and every building block is a nano-sized polymeric nanostructured “molecular material”. It will be demonstrated that the final/desired morphology and phase dimensions of the SPEs may be precisely controlled as is encrypted within the macromolecular characteristics and the chemical composition of the “nanoparticles”. As the synthesis of mechanical robust electrolytes with superior ion-conductivity has been the subject in a wide variety of solid-state electrochemical devices, this approach may significantly contribute to other applications, beyond lithium metal batteries, such as anion exchange membranes for fuel cells, efficient active layers in dye-sensitized solar cells, electrochromic devices and water desalination systems.

Title: Listening to laser light interactions with objects of art: A novel photoacoustic diagnosis approach

Place: A. Payatakes Seminar Room

Date: 29/5/2018
Time: 14:00 (coffee & cookies at 13:45)

Abstract:

Photoacoustic imaging constitutes a novel, rapidly expanding diagnostic technique, which has been predominantly developed in the context of contemporary biomedical research. Recent implementations of various photoacoustic imaging systems have enabled high resolution in vivo imaging of intrinsic biological absorbers such as hemoglobin, melanin and lipids at various spatial scales ranging from cells and tissues to small animals.

In this presentation, I will demonstrate how photoacoustic imaging can break the barriers of biomedicine, and find innovative applications in cultural heritage (CH) diagnostics. Having over three orders of magnitude higher transmission through strongly scattering media compared to light in the visible and near infrared, the photoacoustic signal offers substantially improved detection sensitivity and achieves excellent optical absorption contrast at high spatial resolution.
In the first part of the talk, I will show that such a unique combination of advantages can be exploited to establish a radically new non-destructive methodology for the uncovering and differentiation of well-hidden features in multi-layered CH objects such as paintings and documents. Furthermore, I will demonstrate that the attenuation of the generated photoacoustic signals during their propagation through optically opaque media (e.g. paints) can be used to determine the thickness of thin layers, providing, in this manner, micrometric precision stratigraphic information on the artwork under investigation. Finally, I will present the capabilities of photoacoustic signal detection on the in situ real-time monitoring of laser cleaning interventions, which has the potential to promote an improved conservation outcome by safeguarding artworks’ original surfaces.

Title: Computational Modeling of Nanostructured Materials with Applications in Energy

Place: A. Payatakes Seminar Room

Date: 15/5/2018
Time: 16:00 (coffee & cookies at 15:45)

Abstract: We design nanostructured single-molecule nanoparticles by means of atomistic molecular dynamics simulations. The nanoparticles consist of star-shaped polymers with two types of chemically incompatible arms attached to the star core. This unique structural feature allows us to combine two materials with distinct properties in one single molecule. The immiscibility between the two components gives rise to a nanosegregation into domains and a formation of different intramolecular patterns. We explore wide range of star compositions and the behavior of the particles in two types of media in order to study the relation between the internal structure and final properties of the material. These polymer nanoparticles may serve as the building blocks for hierarchical bottom-up fabrication of targeted nanostructured materials for the realization of new emerging applications, as for example energy storage.
