Abstract:

Rapid endothelialization and healing are critical for successful blood vessel reconstruction following vascular injury (stent placement). Our recent research efforts have demonstrated the ability of our novel technologies, including magnetic stents and PEG-coated magnetic nanoparticles, to enable magnetic targeting and retention of injected particles to diseased artery segments. This approach promotes rapid healing after implantation and may alleviate the need for long-term dual antiplatelet therapy and improve long-term patency. The present proposal focuses on (1) demonstrating the feasibility of functionalized magnetic nanocluster, to controllably delivered and maintained at the site of stent implantation (both on the surface of the implanted magnetic/non-magnetic stent and the surrounding arterial wall); (2) facilitated stented arterial wall endothelialization to mitigate thrombosis and restenosis, as well as signiﬁcantly, reduce or eliminate the need for long-term dual antiplatelet therapy. The project novelty consists in (i) Synthesis and comprehensive characterization of ten PEGylated SPIONs samples with different crystal sizes and PEG lengths; (ii) EX_ VIVO investigations (Seeding efficacy will be studied in the presence and the absence of a magnetic field by placing a magnet (single or array) near the implanted stent (magnetic and non-magnetic stent) in the umbilical artery; (iii) Construction of phantom sets for experimental investigations (made of glass and transparent silicone to highlight the effect of wall roughness for particle deposition); special attention will be paid to the Nanoparticle agglomeration which is a factor with solid adverse consequences in vivo; computational fluid dynamics can model and clarify the entire process of drug administration and drug delivery from the injection site to absorption site in terms of nanoparticles volume fraction, magnetization, artery–magnet distance, size and shape of the coated nanoparticles.

Abstract:

The development of complex nanocomposite materials consisting of different matrices (polymer-like, oxides, intermetallics, liquids) functionalized by different nasnostructured additions (carbon allotropes, magnetic nanoparticles with different organizations, nanostructured semiconductors, etc.) is the aim of this project. The unique combinations of interacting nanophases offeres to the hybrid nanocomposite material new or enhanced proprieties of high interest for applications. In this context, according to the previous experience of the involved teams, the complex project (formed by 4 component projects) is focused on the development of new optimized nanocomposite systems to be included in experimental demonstrators or final products to be transferred to economical companies. The project will contribute both to an increased scientific visibility of the partners as well as to enhancing the institutional performances by the development of new technical and scientific capacities.

Abstract:

Document forgery is a criminal activity that causes billion dollar losses each year worldwide. Security paper is among the most important ingredients used in the fight against the forgery of private or public documents. The continuous diversification and sophistication of the paper securing techniques is one of the most important ways to erect fences against forgery attempts. The NanoMagSecurityPaper project aims to expand the diversity of high tech means for paper securing. The project’s strategic objective is to bring magnetic security paper on the security paper market. It is estimated that the Romanian security paper market alone will demand for tens of tons of magnetic security paper each year.

NanoMagSecurityPaper brings in the idea to obtain magnetic security paper by dispersing superparamagnetic nanoparticles in the wet cellulose pulp. The superparamagnetic paper thus obtained gets the functionality of security paper only together with appropriate validation methods and instruments. In order to meet this goal, joint applied research from the following three fields is necessary: 1. paper making, 2. magnetic nanoparticle/composite synthesis, and 3. magnetic sensing and validation. In order to meet the highest security standards, the authenticity checking procedures should make possible both a fast, handy and reliable first instance validation, and a sophisticated, albeit laborious, high security level validation. The NanoMagSecurityPaper will elaborate and test methods to produce high security level magnetic paper, by embedding in the paper composition magnetic nanoparticles and, for white color paper, magnetic composites. A handy and high sensitivity first instance validation method and instrument will be developed.

NanoMagSecurityPaper will achieve its objectives by transferring fundamental and applied knowledge on magnetometry, magnetogranulometry, magnetic sensing and magnetic nanoparticle/composite synthesis, from three Romanian academic institutions to three Romanian industrial partners: SC CEPROHART SA - security paper producer, SC ROSEAL SA - magnetic nanoparticle/composite producer, and SC DATRONIC-NCIP SRL – electronic equipment producer. NanoMagSecurityPaper will provide high-tech added value to the product portfolio of the consortium industrial partners, as well as a deeper scientific knowledge transfer expertise to the academic institutions of the consortium.

NanoMagSecurityPaper will also open means for the development of securitization techniques for a wide range of diamagnetic materials like paints, textiles, polymeric composites, and others.

Abstract:

Roseal Co. is a SME specialized in manufacturing sealing systems aiming permanently to meet the market requirements. The primary concern regarding to the technology impact on the ambient environment leads for developing new, innovative and environment-friendly products through research. In this context stands the topic of the project – leakage-free sealing system for high peripheral speeds to be used in gas turbocompressors used in petroleum refining and chemical fertilizer industry.

Turbocompressors have large diameters and operates at high rotational speeds, having a high peripheral speed, approx. 30 - 70 m/s in the sealing area. Currently, mechanical seals with barrier fluid or non-contacting mechanical seals with inert gas are used, which don’t ensure hermetic sealing. Moreover, using seals with barrier fluid can contaminate the product, catalyst, etc. On the other hand, inert gas seals require special source supply of clean inert gas and rigouros control of the pressure difference. The maintenance of these seals requires periodical (~ 2 years) change of the rotating active components, a very expensive operation due to the fact that these spare parts must be processed with submicronic precission.

The project proposes the development of new magnetic nanofluid (MNF) seals which has significant advantages compared to conventional mechanical seals: hermetic sealing, exceptionally long lasting operation without intervention (~ 5 years), minimal wear (only viscous friction), virtually zero contamination, optimal torque transmission, wide operating range (10^-8 mbar - 10 bar), relatively simple and cost efficient execution.

The objectives and expected results give a very high degree of complexity and absolute novelty to the project by creating an entirely new generation of leakage-free seal system for high peripheral speeds (30 – 70 m/s) at experimental scale and developing new generation MNF with high temperature resistance up to 140 °C - 180 °C (generated in such type of seals).

The work plan includes tasks in order to achieve the final goal: the synthesis of surfactants for stable magnetic nanoparticles at high temperatures, components of MNFs; synthesis and production of MNF, stable at high temperatures; design, development and manufacturing experimental models of hermetic seals, testing and performance evaluation of experimental models of sealing systems.

Success of the project is assured by the exclusive character of the partnership: CO – ROSEAL is the only manufacturer of seals and producer of MNF with saturation magnetization up to 1450 G for seals in Romania and in Central and East Europe. Worldwide there are less than 10 MNF producers, however they don’t commercialize MNF with saturation magnetization over 600 G; P1 – ARFT, Laboratory of Magnetic Fluids - leader of the international community of magnetic fluids, the only research unit in Romania with well-defined profile in the field of synthesis and characterization of MNFs, being expert in magneto-optical investigation of the influence of magnetic field on the structure of magnetic fluids; P2 – INCDTIM with expertise and equipment in accordance to the European standards for synthesis and characterization of surfactants, characterization of MNF with specific analytical methods, P3 – UPT, RCESCF – expert in rheological, magnetorheological and magnetic characterization of MNFs; P4 – COMOTI – expert in gas turbocompressors with competence for testing at high peripheral speeds. The project implementation responds to SME strategy to develop new, innovative and environment-friendly products by using advanced materials and technologies, thus increasing the turnover and the net profit due to the demand for leakage-free seals in gas turbocompressors on national and international market. Developing a new generation of high temperature resistant MNF opens opportunities for new fascinating applications, as well.

Abstract:

There are three strategies that can be used for seismic protection of structures: 1) reduce seismic demands; 2) enhance structural damping and 3) use active or semi-active structural control. Present project is framed in the third strategy focusing on semi-active systems. A semi-active device has properties that can be adjusted in real time but cannot inject energy into the controlled system. Many of them can operate on battery power alone, proving advantageous during seismic events when the main power source to the structure may fail. One of the most promising devices suitable for implementation into a semi-active control appears to be magneto-rheological (MR) dampers, which succeed in overcoming many of the expenses and technical difficulties associated with other types of semi-active devices. Response characteristics of magneto-rheological devices can be changed by varying the magnetic field through different current inputs. In addition to its small power requirement, the MR damper can generate large forces at low velocities. Currently there are MR dampers with capacities up to 200 kN and research results proved the possibility to obtain capacities up to 400-500 kN.

Present project intends to apply the nano-micro composite magnetizable fluids (MRF), whose properties may be tailored for the use in semi-active MR devices, with expectation to obtain appropriate and easy controllable performance for seismic protection applications, characterized by random low frequency motions of significant amplitudes. Previous experience (patents) of partners in the project consortium on using this technology to produce high pressure rotating seals already exists and offers a good starting base for present application. The possibility of fine tuning of the magneto-rheological response is a highly attractive feature of the nano-micro composite MR fluids, and that will be fully investigated and exploited. The MR response is dependent on the mean size and volume fraction of multi-domain ferromagnetic particles, but also on the volume fraction (saturation magnetization) of the magnetic nano-fluid carrier. The parameters of composition ensure manifold controlling mechanisms of the MR behavior of the nano-micro MR fluids and their fine tuning to the requirements of the envisaged MR damping devices for seismic protection of structures under different seismic motion characteristics. One MR damper of low capacity will be designed, fabricated and tested under different loading conditions (triangular, sinusoidal and random excitations). Numerical hysteretic models will be calibrated on the tested MR damper enabling modeling of structural response. Since the dampers in structural systems will be installed coupled with braces, both single damper and brace-damper assembly tests will be performed. With a numerically simulated control unit, structural systems equipped with brace-damper assemblies will be numerically tested in order to observe and characterize their behavior. The main outcomes of the project are: 1.Micro-nano composite MR fluid recipes for seismic semi-active dampers ; 2.Technical solutions for MR dampers; 3. A 10t MR damper prototipe; 4.Validation tests of brace-damper systems; 5.Numerical evaluation of effectiveness of MR dampers in reducing seismic effects in structural applications. Some of these results ((1) and (2)) might be patented. Moreover, the project will develop and provide an implementation plan, with the further research needs and technological developments aiming at implement in the current fabrication the MR nano-fluid dampers by the industrial partners. A consortium composed by two research centers of PU Timisoara, two research institutions of Romanian Academy, experienced in seismic engineering, complex ferro-fluid applications and structural control, and two industrial partners, with experience and capabilities for fabrication of MR fluids and dampers will be able to achieve the objectives of the project.

Abstract:

To reach the overall goal of developing and scaling-up nanotechnology based magnetofluidic lab-scale methods as innovative micropilot scale technologies, the MagNanoMicroSeal project consortium brings together the high level scientific and technological expertise, skills and know-how of four research groups from two research institutes and a technical university, as well as from a medium sized entreprise partner. A multidisciplinary approach will be dedicated to develop new magnetically controllable fluids, as well as leakage-free rotating seal and adaptive motion controlling devices for electronuclear and hydraulic power units. The workflow is organized along the following main directions: lab-scale and micropilot scale synthesis of high magnetization and radiation resistant magnetic nanofluids and nano-micro composite fluids for heavy duty (high pressure and /or rotation speed, contaminated medium) rotating seal and semi-active magnetorheological motion control applications; advanced structural, magnetic, rheological, magnetorheological characterization of the new magnetizable fluids; accelerated (irradiation) ageing and sealing capacity tests; design, manufacturing and experimental testing of leakage-free rotating seals for nuclear equipments and magnetorheological rotation speed controller devices for hydraulic turbomachines. The strong link to market needs is assured through the midsize company ROSEAL SA participating with major contributions in the project. The new rotating seal and motion control systems for nuclear and hydraulic equipments offer better quality than usual solutions have, will help to gain new market shares and open technological advantages over traditional manufacturing routes. The seal systems proposed for nuclear equipments offer much higher level of environmental protection over traditional sealing units due to the leakage- free property of magnetic fluid rotating seals, increasing the commercial value of the solutions proposed.
