Abstract:

The project " Novel Mg-Ca-Zn biodegradable metallic materials used in orthopedic applications " proposes the elaboration of biodegradable materials from the Mg-0.5Ca-xZn system for use in medical implantology. In the last decade, many researchers have made progress on biodegradable Mg-based alloys with applications in medicine. The unique chemical composition of these alloys offers all the premises of promising results regarding bone regeneration and the elimination of the 2nd surgery. The use of these elements leads to a considerable increase in corrosion resistance, biocompatibility and mechanical properties. The project has a strong multidisciplinary character, due to the complexity of the the studies will focus on testing this class of biodegradable materials through microstructural analysis (OM, SEM and XRD), tribological tests, electrochemical behavior in SBF, cell viability tests (in vitro analysis –MTT method) and in vivo analysis on laboratory model animals. These results will contribute to the certification of the preliminary information obtained and the confirmation of the controlled and biocompatible biodegradable character of the Mg-0.5Ca-xZn alloys used in orthopedics. The project aims to identify an optimum concentration of the Mg-0.5Ca-xZn system, to publish the results in international journals with ISI impact factor, to submit the patent documentation and to identify the users and manufacturers of biocompatible materials for the technological transfer.

Abstract:

The Complex Project "OBTAINING AND EXPERTISE OF NEW BIOCOMPATIBLE MATERIALS FOR MEDICAL APPLICATIONS" - MedicalMetMat, is proposed by a consortium of 10 partners, coordinated by Technical Univ."Gh. Asachi" of Iasi. It is a complementary and interdisciplinary scientific consortium of specialists from 2 technical universities (TUIASI and UPBucharest), 2 medicine universities (UMF Iasi, UMF Tg Mures), a veterinary medicine university (USAMV Iaşi), UAIC Iasi and UDJG Galati universities and as well 3 R&D institutes with possibilities for economic recovery (IFT Iasi, INOE Magurele and ICPE-CA). The consortium proposes the realization of 5 research projects, 4 focusing on the production and expertise of metallic biomaterials for various medical applications (biodegradable materials for orthopedics-Pr1-ORTOMAG, biomaterials for medical prosthesis-Pr2-BioTIT, biomaterials for dental applications-Pr3-BIODENTRUT and biocompatible alloys with high entropy for medical applications-Pr4-HEAMED). These projects provided production stages, structural/physico-chemical/mechanical analyses performed by specialists from technical universities and research institutes; In vitro cell viability tests, conducted by specialists from the medicine universities and in vivo determinations (veterinary specialists) by osseointegration study and the resorption rate by animal experimental model, which will conduct to the expertise and approval of these metallic materials for the manufacturing of medical applications. Project Pr5-SOLION presents methods for increasing biocompatibility for the obtained biomaterials in the previous 4 projects, through specific coatings and aerosols systems.

Results dissemination of the Complex Project is aimed to patenting and recommending for the approval of optimal compositions, for implementation in the economic/medical environment and preparation of technology transfer to producers and beneficiaries in the field of production and distribution of medical devices.

Abstract:

Following the European policies on risk management in emergency situations, security systems and human health protection, it can be acknowledged the importance of the detection subsystem (that covers the protection against pollutants).

Since the sensing mechanism used by the gas sensors is based on a surface reaction and a high surface-to-volume ratio, it is unanimously accepted that the electrospun nanofibres, which are characterized by a specific surface area of about one to two orders of magnitude greater than the flat films, are exceptional candidates for applications in sensors.

Electrospun nanofibers can be easily molded into microelectrodes, which show a significantly better response to various gases than conventional films.

The operator holds the technology and the computer multijet needle electrospinning equipment. The operator needs to increase the production of electrospun nanofibers, a current goal in the international research, which is stipulated in the project through the assimilation / development / optimization of the electrospinning technology with debiting mechanism (jet and multi-jet) with interchangeable punctured electrodes (fixed / mobile) to obtain 3D structures for security applications.

In order to obtain bigger absorption, specific morphological characteristics are required and this is why the 3D nanostructures obtained by electrospinning are suitable for gas detection applications due to their multiple well-known advantages.

Replacing the needle mechanism with a interchangeable punctured electrodes mechanism ensures increased production of electrospun nanofibres and the possibility of obtaining 3D nanostructures capable of identifying harmful compounds (acid/alkali) in the environment; this constructive change of the debtor mechanism requires tests /analyzes/experiments/validations/ optimization obtained by the expertise of the university research team.

The project aims to develop at S.C. MECANO FUC SA, two innovative technical equipment (grasslands recovery machine and trailed windrower for forage conditioning and harvesting) that are used to develop rational grasslands in terms of climate change.

Grasslands recovery machine is designed for grasslands quality restoration technology through soil preparation in narrow bands and seeding directly in the grassy carpet of a mixture of herbs or even a single species, preserving all or a certain percentage of existing vegetation.

The trailed windrower is designed for harvesting and forage conditioning technology, performing a shift mowing operations, crushed and left on the soil in the furrow continues to dry naturally.
