Abstract:

Novel biomaterials for temporary orthopedic implants are one of the most challenging areas of exploratory research in advanced materials. Third generation biomaterials are designed to be both resorbable and bioactive, that is, the implant will be temporary, and once implanted, it will help the body heal itself. The aim of this project is to progress toward a novel absorbable scaffold biomaterial for temporary orthopedic implants, through hierarchically structured surfaces that protect the scaffold, effective to convey higher corrosion tolerance and increased scaffold strength retention for extended periods in body fluids while at the same time capable to stimulate human osteoblast cell proliferation behavior. Specific objectives are (i) the design and fabrication of 3D printed scaffold structures with biocompatible elements by rapid solidification from melt through laser additive manufacturing-3D printing; (ii) the development of original cost-effective surface modification procedures for surface protected scaffolds (SPS) with enhanced corrosion tolerance and bioactivity; (iii) the determination of bare and SPS corrosion rates and corrosion mechanisms in human physiological fluids of pH and chloride concentrations reproducing the most exigent conditions for implant use; and (iv) the assessment of the scaffold-cell constructs to initiate tissue repair processes and osteogenesis; contributing to Romanian research with: 1 patent, 4 scientific articles, 6 conference presentations

Micro-nanotechnologies for monitoring of greenhouse gases Call name: P 2 - SP 2.1 - Proiect experimental - demonstrativ

Abstract:

The main purpose is the monitoring of greenhouse gases which are directly linked with the human activities. To this scope the project will develop a new technology for the fabrication of smart, miniaturized sensor array for greenhouse gases monitoring. A microsensors array based on alumina transducers and MOx (metal oxides) and polymer materials will be developed. The targeted gases considered as main contributors to the greenhouse effect, are methane, ozone, carbon dioxide and water vapors. The microtransducers are made up of alumina µ-chips with interdigitated gold electrodes on top (front side of the transducer) and platinum microheater on the backside. The microsensors array will contain undoped and doped MOx sensitive films (SnO2, ZnO, SnO2-ZnO, CuO) and polymers deposited by safe and low-cost chemical routes (sol-gel and hydrothermal method).

The novelty of the project consists of: a) the significant improvement of properties of the proposed materials by controlling the nanometer-level architecture oxide (nanowires) and by utilizing the multilayered mixed structure containing MOx and polymeric films; b) new technology for microsensors fabrication on thin alumina with very low power consumption. A laboratory platform and a mobile apparatus for gas detection will be tested. In Romania a project focused on monitoring of greenhouse gases, comprising detection, correlated with geographical and environmental conditions, data acquisition and interpretation is new. The two years duration will allow to optimize and to demonstrate the technology up to TRL 4, to fabricate the sensors (TRL 4), to start the data acquisition and interpretation. All these developments will allow a long-term prediction algorithm for pollution evolution, geographical mapping of areas with the highest pollution, prediction of local and global warming, under different RCP scenarios (Representative Concentration Pathways), monitoring of local evolution of these gases.

Abstract:

Most human environments are characterised by the presence of a large number of chemical substances which mainly belong to the group of volatile organic compounds (VOC). Numerous studies revealed the toxic and carcinogenic effects of these VOCs which usually can be found in indoor air, but the tools for the detection of VOCs are still not very precise and too expensive.

The project will develop new sensors based on nano MOX and CNT materials for VOC detection, integrated into a smart portable system providing quantitative information about the concentration of Formaldehyde and Benzene in indoor air.

The results will be:

- Technology demonstrator and Smart, portable system prototype and new formaldehyde and benzene sensors;

- Technology for thin sensitive films deposition and integration in the microtechnology steps flow for sensors fabrication on silicon – Demonstration;

- E-Nose system, including sensor array, data processing algorithms and software for VOCs accurate detection.

Abstract:

The Complex Project “Sensors and Integrated Electronic and Photonic Systems for people and Infrastructures Security” aims to develop new sensors, new integrated electronic and photonic systems for detection of explosives used in terrorist attacks or accidentally released in military bases or industrial sites.

The Complex Project is developed through four distinct projects, called “components” which are converging to the Project goals by detection of explosive substances and increasing the security of people and infrastructures, as follows:

1) Design and development of a portable microsystem, based on TF BAR sensors arrays, for multiple detection of explosives (TATP, HMTD, TNT, RDX, NG, EGDN) used in terrorist attacks; 2) SiC-based hydrocarbons sensors for measuring the hydrogen and hydrocarbons in hostile industrial environments; 3) Infrared sensors for dangerous gases detection, such as explosive gases (methane) or pollutants (carbon dioxide / monoxide); 4) Design and development of a piezoelectric energy micro-harvester, able to generate electric power in the 100µW range, used for powering up sensors and portable microsystems used in explosive gases and substances detection.

The complex project description includes the novelty elements, detailed activities description, the working procedures within the consortium, expected results and deliverables. The deliverables has an average TRL 5, which means all four component projects will have a high technological level and the result’s maturity will reach at least successful laboratory testing.

The project will deliver the sensors and integrated systems along with the energy micro-harvester as physical objects and technologies, functional and laboratory- and real conditions tested, scientific papers and patents. The project’s high impact on the participants and also the social impact are detailed.
