Abstract:

The research interest in methods and materials for clean energy generation and storage in a sustainable manner is driven by the rapidly growing global energy demand and the negative effect of greenhouse gasses. Converting solar energy in electricity and fuel is the main focus of renewable energy research. The world’s photovoltaic capacity of the existing technologies is still limited. Due to the intermittent nature of sunlight, a separate energy storage mechanism which is effective and environmentally harmless is required for solar energy to fully replace fossil energy. This makes photoelectrochemical cell an interesting alternative. The present proposal addresses these concerns for renewable energy production and storage by designing new nanostructured systems that are based on double oxide ferroelectric materials, for which recently reported experimental results and theoretical studies showed promising characteristics. High quality absorbing materials with structural, optical and ferroelectric properties that efficiently convert the solar energy into electricity will be obtained using new experimental configurations based on pulsed laser deposition and high power impulse magnetron sputtering. Also, different cell architectures with multi-layered configurations are considered. The achievement of this project general objective will bring significant contribution to the sustainability and future commercialization of photonic devices as sources of renewable energy.

Abstract:

Spacecrafts (such as CubeSat) in low Earth orbit (LEO) are exposed to several hazardous environments including the impact made by micrometeoroids and orbital debris (MMOD). There are 500,000 pieces of debris that are currently tracked and there are more than one million small debris pieces that can’t be tracked due to their small size. Collision results made by a piece of space debris can cause mechanical damage, material degradation, and, occasionally, the catastrophic breakup of operational spacecraft. Expeditions like Apollo 13 or STS-107 failed due to the lack of identification of external damages in the spacecraft. The project aims to develop a large-scalable method and a modular sensing technology based on silicone elastomers suppressing the disadvantages of other technologies intensely studied at the day. Basically, the proposed project aims to determine in real-time when an MMOD impact has occurred on a spacecraft shield or structure, area of the impact, depth, and importantly, where it occurred. Moreover, the proposed sensing technology will be operating on a wide temperature range (-70 to more than 150 oC), being lightweight and able to give real-time feedback to the operator, can detect simultaneous multiple damage impacts of different projectile sizes, as well as recovering the original shape after taking damage will be possible (self-healing properties).

Abstract:

Binary oxynitride-type compounds (Me1Me2OxNy) have received significant attention in recent years due to their original properties compared to their oxide or nitride parents. The project’s intention is to study the chemical, structural, morphological and, consequently, property variation concerning transitional metal-based multiple component oxynitride-type thin films (where Me1, Me2 = Ti, Ta, Zr), obtained by simultaneous sputtering of two metallic targets, with the addition in various proportions of reactive gases (N2 and O2). Novel multifunctional transitional metal binary oxynitride-type thin films will deliver enhanced performance and enhanced cost/benefit ratio for certain applications: protective coatings, microelectronic devices, optical coatings, biocompatible coatings.

Abstract:

The actual purpose of the fusion international community is to demonstrate the generation of electricity in fusion power plants .

Achieving the European Fusion Road Map requires solving several fusion challenges which are highlighted in the EUROfusion Consortium Work Plan 2014-2018.

In this long-term Work Plan, one Work Package is devoted to the “Preparation of efficient Plasma-Facing Component (PFC) operation for ITER and DEMO”, because

among the main problems related to magnetic fusion reactors is the behaviour of materials exposed to high fluxes of radiation and heat transported by particles

coming from the plasma core through the edge plasma, as well as the plasma-wall transition.

In this general context, the aim of the present project is to study the interaction of high density transient plasma with W and C targets (these materials being

among the main candidates for PFC) in laboratory devices. Two main aspects of this interaction are foreseen: the direct impact of the plasma on the target material

and the behaviour of the sputtered material into the discharge. To achieve the goals of the project we will investigate the erosion of the targets, the sputtered

material fluxes and the thin films resulted from the deposition of the sputtered material on different substrates, in hydrogen, deuterium and argon-nitrogen plasmas.

Abstract:

Thin films deposition is a process extensively used in almost every industrial branch, from ultra-high-tech to domestic commodities. Research on materials processing showed that physical and chemical properties of deposited films are different from the bulk material being highly dependent on the synthesis method.

The project has the main goal the manufacturing of a compact plant for thin films deposition, designed for applications and scientific research, training and education. The deposition plant works for a wide variety of materials (metals, alloys, oxides) due to the pulsed operated power supply incorporated. The sputtering system uses the magnetron cathode concept, resulting a plant based on the process known in the literature as High Power Pulsed Magnetron Sputtering (HPPMS).

The innovative feature of the plant is the control of the deposition process by managing the sputtered material losses through the successful combination of the pulsed power supply, cathode magnet configuration and the additional magnetic confinement. Compact, the deposition plant is highly recommended as laboratory device for educational purposes. It is also an excellent forerunner for large scale production, sustaining small scale pilot experiments to improve the technique and process of new materials deposition. The applicative value of our deposition device is sustained by the quality improvement of the thin films deposited by the new HPPMS technology. The plant is offered as low-cost basic equipment for training in the field of PCVD. Optional it can be upgraded to high-performance plant for research and small production.

The consortium brings together specialists from plasma physics (CO), engineers from a small enterprise (P1) and specialists in thin film coatings and film characterization (P2).

The prototype of the compact plant for films deposition, accompanied by users manuals describing the typical operation modes and facilities constitutes the end product of the project.

Abstract:

SNON project focuses on the complementary solution of using the sun light for hydrogen production the photo-electrolysis. A large panel of metal oxides and

nitrides are candidates, but most of them have the optical gap in the ultra-violet range. SNON project aim to explore a different class of materials based on Tantalum

and Zinc oxy-nitrides (from Ta2O5 to Ta3N5, and ZnO(N)) with different micro- and nano-structure, from nano-particles to the ultra-thin and dense films. The main

interest of them is the decrease of the gap making them sensitive to visible light range, which intensity is dominant on the Earth.

Abstract:

The present research project proposes the use of plasma techniques to functionalize nanoprobes in order to obtain surfaces properties required in biological applications of scanning probe microscopy and nanotechnology. Most of the effort is focused on functionalization of silicon and silicon nitride probes used in atomic force microscopy (AFM). The techniques proposed are an alternative to the common wet-chemistry functionalization method of self assembled monolayer (SAM) depositions of organothiol or organosilane molecules. Plasma cleaning, oxidation, and hydroxylation processes are used to chemically activate the silicon and silicon nitride nanoprobe surface by generating hydroxyl groups. These processes are followed by chemical vapor deposition (CVD) of organosilane molecules in order to generate surfaces reach in amino, carboxylic, or methyl functional groups. The novelty of the proposed method consists of using plasma activation of nanoprobe surface fallowed by CVD of monomer molecules. The capability of the obtained functionalized nanoprobes to offer bioconjugated surfaces to various biomolecules will be estimated by AFM measurements of surface-molecule bounding strength. Success and stability of functionalized AFM nanoprobes will be evaluated by AFM pH titration force spectroscopy and protein binding strength experiments. The plasma functionalization methods developed for the AFM probes will be extended to functionalization of silica nanoparticles.
