Abstract:

Wastes from agriculture and fishery cause harmful effects on the environment and implicitly on humans. But, many of these wastes can be recycled. One of the current global issues refers to minimizing waste production, effective wastewater treatment, biosafe food production, and reducing hazards from the exposure to pathogens. Most of the threatening microorganisms especially emerging pathogens (EPs) derive from wastewater. Moreover, antibiotics residues present in wastewater lead bacterial pathogens to develop antibiotic resistance genes (ARGs). In addition, heavy metals are among the most harmful non-microbial pollutants due to their toxicity to humans. BIOSHELL aims at synergistically solving economic, environmental and health problems. The project focuses on utilizing the wastes from sea food preparation such as crustacean carcasses in the development of innovative and efficient inorganic-organic functionalized hydrogel nanocomposites, suitable to facilitate the sustainable wastewater purification technologies about heavy metals retention, antibiotics elimination, EPs and ARGs removal.

Abstract:

The main objective of this project is represented by the transfer of an innovative decontamination technology that involves the utilisation of some strippable polymeric coatings for the decontamination of radioactive or heavy metals, from the academic research towards the industrial partner STIMPEX SA. This project idea appeared due to the extremely important problems related with environment protection, because every year increasing quantities of hazardous waste like radioactive or heavy metals are identified as result of the use of these contaminants in defense and security industry (primers, detonators), nuclear power industry, medicine, which lead to negative consequences. In order to reduce the harmful effects caused by these contaminants, this consortium aims to develop an innovative decontamination method for the surfaces. The polymeric films will be obtained on an industrial prototype scale, using a green synthesis method based on ecofriendly, biodegradable, nontoxic and low-cost raw materials. The synthesized decontamination solutions will be applied by spraying them over contaminated surface or they can be stretched with a roller or a brush and after drying, the resulting films can be removed by their simple exfoliation, thus removing also the contaminating agent embedded in their polymeric matrix.

Abstract:

The project TOXINSENS refers to designing innovative, versatile and re-usable biosensors for the fast, qualitative and quantitative detection and monitoring of lipopolysaccharides (LPS- endotoxin derived from Gram-negative bacteria, GNB) in various biological, food or water samples. For this matter, a medium consortium was created taking into account the project interdisciplinary and complexity, which includes the Project Coordinator ICECHIM that owns the background of the Concept approached in this project proposal, a Partner with state-of-the art facilities for characterisation i.e. UPB and a SME Partner-EPI SISTEM SRL capable of testing the project prototypes, adsorbing the know-how of manufacturing and commercialise the resulted LPS-biosensors. The project on-set refers to the following bioinspired concept: Methodology for the preparation of LPS-sensitive films-TRL 2. The concept was originally proposed by the Project Leader and developed within the Advanced Polymer Materials & Polymer Recycling Group from ICECHIM on project TE123/2018 BACTERIOSENS. Starting from this point, TOXINSENS targets first the upgrade of this former concept by addition of electro-active nanoparticles to the precursor films solution. In this way, an electro-active hybrid paste will be generated and used to print LPS-hybrid films directly on blank ceramic electrodes (TRL 3). The prepared LPS-Screen-printed hybrid electrodes will be further tested in laboratory-relevant environments and the innovative technologies will be thus validated (TRL 4). The specific output of the project will lead to several outcomes during project implementation (short-term scenario: at least 3 publications, 3 communications at prestigious Symposia or Congresses and 1 patent claim), and also after project end (long-term scenario: research and development roadmaps, performance data, transferable knowledge).

Abstract:

SECURE-NET is a Complex Project designed to improve the institutional performance of the Consortium Research Partners (Institutions with Re-launch Capabilities in the Field of National Security). In this respect, the Complex Project proposes five research themes corresponding to the five Component Projects, which aim at: (i) contingency of chemical, biochemical, radiological and nuclear (CBRN) hazards by developing new decontamination products and by developing specific sensors for detecting chemical agents of combat, and (ii) improving national security by developing shock-absorbing composites, solid rocket fuel and multispectral camouflages. This Complex Project brings together institutions with tradition, having either similar specialisation or complementary specialisation, to strengthen scientific and technical competences in the field of National Security and Advanced Materials for military applications. The Project Consortium has a gender-balanced staff and promotes the involvement of a large number of teachers, researchers, doctoral students and post-doctoral students in all activities proposed by the Common Agenda. In addition, the project facilitates the transfer of scientific knowledge between participating institutions as well as the recruitment and training of new staff. The multitude of results generated by the implementation of SECURE-NET express the potential for significant influence upon (i) the scientific community through communication and dissemination of results (as a short- and medium-term impact), and (ii) the public and private environment by promoting new research services and new transferable products / technologies to the external environment of the Consortium, particularly to the national defence industry (as a long-term impact).

Abstract:

Propulsion powders, which are the basic load of rocket engines, are found in the literature as propellants. Propellants are combustible materials containing high amounts of oxygen required for their combustion and, hence, their main function is to impart motion to a projectile or missile. For rocket engines, generally solid heterogeneous propellants are used. Propellants are composite materials made up of three basic components: a binder, a solid oxidant and a metallic fuel additive (carburant). The most used binder for propellants is hydroxyl-terminated polybutadiene (HTPB), which is expensive and implies specific transportation and manipulation requirements. Therefore, the aim of this study refers to partial or total replacement of HTPB with cheaper, more efficient and ecological products. In the literature, there are numerous studies on replacing HTPB with polyethers or polyesters to lower production the costs. Yet, no studies were found on the use of polyols obtained from polyethylene terephthalate (PET) waste. Preparing polyols from polyethylene terephthalate (PET) is cheaper mostly due to the synthesis method. In addition, the aromatic residue of PET confers rigidity, compared to aliphatic residues, which is a desired property for solid rocket fuels. Herein, the polyester-polyol synthesis was performed in successive steps: Glycolysis- PET depolymerization in the presence of polyethylene glycol 600 (PEG600); Transesterification with vegetable oils; Esterification, with aliphatic dicarboxylic acids or derivatives, of the PET solvolysis products (resulting from the glycolysis and transesterification reactions). The polyols obtained were reacted with different isocyanates to obtain rigid polyurethanes (example: PU-R9 and PU-R10) able to replace HTPB. The new formulations of polyurethane binders for rocket propellants were characterized by FTIR, TGA, DMA and tensile tests to emphases their structure and stiffness. In the next step, the carburant will be added and the binding properties will be assessed.
