Abstract:

This project will materialize in transdisciplinary collaboration between the team of specialists: archaeologists, archaeometry, and computer scientists and will lead to the development of 3D technologies (3D laser scanners and photogrammetric methods) for storing information in digital format about the Dobrogean medieval heritage built of stone (Sacidava Fortress) which has not been investigated so far. The new 3D technologies proposed to be used for scanning, photography and moving, will serve to map the archaeological site and will be supplemented with physicochemical and biological studies, through analytical techniques of structural, compositional, and morphological characteristics to assess chromatic uniformity, degradation status, and other information related to the period, geographical location, shape, construction material, level of degradation. It is known that the artifacts are particularly vulnerable, and their release from the environment where they were buried accelerates the processes of corrosion and degradation, which can lead to the destruction of archaeological evidence.

The characterization of historical materials will include non-destructive methods in situ and in the laboratory: chromatic analysis, UV-Vis and FTIR spectroscopy, X-ray diffraction and fluorescence, Raman spectroscopy, optical microscopy, SEM / EDS, thermal analysis, compressive strength, strength to frost, the crystallization of salts. Based on the results obtained, tests will be performed on model substrates prepared in the laboratory and on real samples (received from site archaeologists, in compliance with legislation) by using nanomaterials (substituted hydroxyapatite derivatives) that meet the criteria of compatibility with historical materials. The mapping of this archeological site, its degradation state, the elaboration of new solutions for the conservation of the stone surfaces exposed in the atmosphere and humidity due to the proximity of the Danube, will be achieved.

Abstract:

ASPIRATION will create a strong relationship between cultural heritage, conservation, technological innovation, economic development and competitiveness, contributing to the safeguarding and understanding of cultural property, in its aesthetic and historical meanings, physical integrity, context and social aspects. The project will respond to serious preservation/restoration problems of paper historical objects, offering solutions through a new multi-steps preservation process, such as cleaning fragile cellulose-based documents, metal-inks ‘corrosion’, conservation treatments by mass de-acidification, creating an alkaline reserve, a proper storage environment for the treated bio-based materials (books, papers, textiles, leather, wood) within archives or museum collections, combining the eco-friendly solvents and nanotechnology and with a protection process for storing the artefacts in an oxygen depleted atmosphere. The project will offer a clear presentation and argumentation of TRL, the solutions already patented being transferred from the experimental proof of concept (TRL3) (EP2626464 B1) technology validated in lab (TRL4) through testing and validation of the whole treatment process: non aqueous de-acidification, significant improvements of paper cleaning surface (by gellan, psyllium and synthetic silicate colloidal gels), dye corrosion, strengthen with polysaccharide compounds (CMC) with a minimal stress. Also, will be a transferring process from technology formulated concept (TRL2) to (TRL4), for the storage steps in order to reduce the degradation for a long time (> 20 years) by setting a protective oxygen depleted atmosphere storage process, to avoid the impact of degradation due to the presence of atmospheric oxygen and with low protection costs. In integrum, will be a concerted treatment/cleaning/storage technology of conservation for the books and manuscripts paper from library and archive materials.

Abstract:

Although in 2016, at global level, the quantity of WEEE was over 45Mt (increasing 3-5% yearly), the estimated recycling rate only reaches 15-20%. Out of the total WEEE quantity, IT and telecommunication equipment waste (WEITT) represents c.a.15%, while printed circuit board waste, albeit only 3-6% of the total DEIT waste, concentrates 40% of the recoverable metals. At international level, the usual industrial technologies are mainly based on physical-mechanical and pyro-metallurgic procedures, but require high energy consumption and generate toxic by-products. At national level, reported research on WEITT processing is limited to the laboratory, while industrial processing agents only collect DEIT for export.

The consortium, composed of the Technical and Babeș-Bolyai universities of Cluj-Napoca, "1 Decembrie 1918" of Alba Iulia, Technical "Gheorghe Asachi" of Iași, INDO-INOE 2000 Research Institute for Analytical Instrumentation subsidiary ICIA and the National Institute for Research & Development in Chemistry and Petrochemistry, will elaborate, test and validate a complex of installations and optimised technologies for the integral reclaiming of WEITT materials, based on the following principles: 1) minimal energy consumption and reduced quantities of secondary waste, with reduced environmental impact, 2) smart disassembling and separation (mechanical, electrical and electrochemical) in order to obtain new or recycled materials with high purity and high economical value, 3) valorification of resulted plastic materials through non-polluting chemical technologies and their reintroduction in the production process, 4) development of a platform for monitoring environmental impacts and for learning reclaiming technologies for DEIT material 5) transfer of the developed technologies to companies in the Romanian reclaiming and recycling industry.

Abstract:

This project aims the development and implementation of an innovative obtaining process of high-impact resistant composites and endurance based on recovered polypropylene.

The practical objective of the project is to improve the competitiveness and the level of technological development of the beneficiary (S.C. BERIMPEX SRL) by implementing the obtaining procedure of innovative high-impact resistant recovered polypropylene composites.

The reintroducing into the economic circuit of recovered polypropylene especially from technological waste and packaging leads to significant energy and material savings compared to the monomer and subsequent polymer synthesis, contributing also to environmental decontamination.

The final point of the project will be the composites implementation to the beneficiary which will materialized in replacement the raw materials used in present (native polypropylene) to obtain different items by injection molding.

The use of the composites based on recovered polypropylene and styrene-diene block-copolymers as raw materials instead of native polypropylene will lead to a 32 % decrease of the manufacturing costs, also ensuring superior impact strength and an increase of about 50 % of endurance, elements that are prerequisites both for the production growth and diversification and for widening market outlets.

Peroxynitrite: Relevance for Food Safety and Novel Electrochemical Detection Call name: Exploratory Research Projects - PCE-2011 call

Abstract:

Considering this toxicity potential of peroxynitrite formation in meat with impact for food safety, it is proposed herein to develop advanced tools to quantify the presence of peroxynitrite in food: meat, in real-time in situ. While there are several detection methodsavailable for peroxynitrite (e.g. oxidation of fluorescent probes, EPR spectroscopy, probe nitration, chemiluminescence, immun-histochemistry) these tend to be more elaborate and difficult to apply for real-time quantification, due to their inherent complexity. The electrochemical detection of peroxynitrite would be a simpler and more convenient technique.

Based on initial results and specific knowhow, the team final goals are to develop electrochemical ONOO- sensitive in situ methods, based on new/improved (metalloporphyrins and conjugated polymers) nanocomposies, for detection its dynamics in foods such as meat-fish tissue and use the results to better understand ONOO− implications for food quality and safety. Once perfected as analytical tools, the peroxynitrite microprobes could be studied for possible use in pharmacology and toxicology.

Abstract:

The main goal of this project is to reintroduce the recovered polypropylene after its lifetime use in the economic circuit as high performance composite materials. There will be used the current industrial technology for melt alloying of the components. The project task consists in the obtaining of new styrene-isoprene block copolymers with thermoplastic elastomeric properties for advanced recycling of recovered polypropylene. A new technology is proposed for the obtaining of styrene-isoprene block copolymers-recovered polypropylene composite materials with high performance impact strength especially below 0°C. The recycled composite material is cheap and shows higher impact strengths (2-4 times higher) even than the unused initial polypropylene form current production according to our recent experimental results. Therefore, advanced recycling of polypropylene wastes could be ensured with favourable effects for depollution and environmental protection.

The present research focuses on establishing the molecular and compositional parameters for styrene-isoprene block copolymers resulting in recovered polypropylene composites with optimum properties.

The synthesis of styrene-isoprene block copolymers will be done by solution sequential anionic polymerization of monomers with n-BuLi as initiator which permits precise and reproducible block copolymers to be obtained. The molecular weights of the polystyrene and poly-isoprene blocks are well defined with a narrow distribution.

Solution polymerization is a modern non-polluting technique with low water consumption and the solvent is fully recovered at the end of the synthesis of styrene-isoprene block copolymers and then reused. In this way the resource is preserved and the environment is not polluted with waste waters.

These block copolymers will be obtained with certain structures and physico-mechanical properties so that their melt alloying with recovered polypropylene will lead to high impact composites.
