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:

Electricity demand has a high impact on a broad range of applications in the automotive industry. Due to the higher costs and energy consumption growth, in most of the automotive applications the electromechanical devices are replaced by embedded semiconductor devices. A specific design feature within this field is to guarantee the circuit operation under repetitive stress for a minimum number of switches (repetitive clamping or short), until 0 defect rate. Most of the times such a design is faced to extensive trial and error, involving huge human resources and a considerable time to market.

Infineon Technologies Romania (IFRO) has as main activity the design of power integrated circuits (IC) for automotive industry. In IFRO activates a research group in the development of methods and methodologies - including simulators – for the optimization of power IC’s. The main objective of the project SET4CIP is the developing of a new generation of electro-thermo-mechanical simulator pf power IC’s by integrating the numerical simulation models and software developed by the research team of the Technical University of Cluj Napoca (TUCN) on top of the simulation and testing platform used by IFRO. The multiscale-multigrid concept (iterative simulation by progressively increased resolution based on the extended finite element and level set methods) developed by TUCN allows: a) the correct assessment of the most likely failure mechanisms; b) the correct assessment of the most likely failure points and; c) the comparison of relative robustness between variations (layout, bonding diagram or package) of the same design.

The proposed innovative concept sustains the development of a new theory and new approaches of the electro-thermo-mechanical simulations and provides a high degree of interdisciplinary. The new approach will allow the migration towards new applications, such as electroless deposition, corrosion, cracks due to corrosion, oxide layer growth and formation, etc.

Abstract:

The present proposal answers to two challenges of the electrification of passenger cars: noise-vibration-harshness (NVH) and electromagnetic compatibility (EMC) issues connected to the electrical actuators integration in different subsystems of the vehicle from auxiliaries to powertrain. The thematic of the project is correlated with 7.5.4. (Products and technologies for automotive industry), touching also 7.5.3 (Increasing of safety and security of the transport).

The automotive industry has a continuous high demand for electric drives. The field of actual automotive electric powered units spans a broad range including cooling fans, window and chair actuation, steering, braking, suspension, starter-alternator (integrated or belt driven), HVAC, propulsion for hybrid and full electric vehicles (HEV/EV). The further enhancement of high-performance automotive electric actuation requires energy-efficient, reliable, robust, low-cost electrical machines and highly integrated, energy-efficient power electronics and control modules. For achieving these requirements, the R&D activities should focus on the analysis and development of new topologies and concepts of electrical machines, taking into account the need for energy efficient drives, the harsh automotive environment (high temperature, vibrations, standards for the measurement of pass-by noise, etc.) and the availability of raw materials (in particular rare-earth materials for permanent magnets). Moreover, the integration of electric powered units in vehicles represents an important challenge due to strict and specific noise-vibration-harshness (NVH) and electromagnetic interferences (EMI) requirements.

Therefore, in the context of this new vehicle design paradigm, it becomes critical to understand and manage the interaction between different fields of physics (electromagnetism, thermal, mechanics, acoustics) for the design and development of electrical machines and drives (EMDs) for automotive applications, where both the environment and the specifications are placing more severe restrictions and demands. Moreover, the multi-physics approach should be extended from component- to system-level taking into account the multiple domains that are interconnected and influence each other. The electromagnetic, thermal, mechanical and vibro-acoustic design of the system must be considered simultaneously if the specifications are to be satisfied in the given environment and under specific NVH and EMI requirements. The four designs required for system integration are tightly interconnected and any change in one design will have consequences on the remaining three.

The interdependencies between the electromagnetic design of the most used electrical machines - induction machine (IM), permanent magnet synchronous machine (PMSM) and switched reluctance machine (SRM)- and their thermal and vibro-acoustic behaviour are already under study since several years. However, the generated vibrations are not only an important cause of faults in the driving motor and of annoying noise, but also cause distortions of the controlled excitation current and consequently affect the EMI characteristics at component- and system-level.

In this context, the present proposal unifies knowledge, equipment, and competences in a coupled EMI and vibration analysis in order to identify the key factors in the development of safe electrical actuators for automotive applications and the integration of NVH and EMI issues from the early beginning of their development phase.

The project will approach two new comers in the electric powered automotive units, i.e. switched reluctance machine (SRM) and synchronous reluctance machine (SyRM) and their drives, by comparing their global (torque and efficiency) and specific (NVH and EMI) performances to the ones of permanent magnet synchronous machine (PMSM) drives in order to develop safe automotive electrical actuators.

Abstract:

The project addresses a basic improvement of the present. widely used Electro Chemical Machining (ECM) technology. The new technology will be developed from the present laboratory stage to a reliable. predictable and ecological clean mass production technology for precision parts. The accuracy will be improved from the present 0.25 mm. by at least two orders of magnitude and recycling of the dissolved metals will solve the urgent waste problems as encountered with the present technology, that produces 8,000 tons/year of chemical waste containing highly toxic chromium 6 and other heavy metals. The feasibility of the SPECTRUM will be shown by producing key components and the technology will be made available to the partners as well as to the European industry.

Abstract:

The population dynamics of cyanobacteria in 3 reference lakes was described by a polyphasic approach. Thousands of DNA sequences from cyanobacterial strains and environmental samples were obtained from Finland, Poland, Czech Republic, Belgium, Luxembourg, France, Italy and Spain. The toxicity of selected strains and samples was determined. A demo version of the microarray has been successfully tested with strains. For environmental analyses, the use of the DNA microarray involves a quite long learning process. A research version of the special software to calculate diversity indexes using molecular data (Community Sequence Analysis)is available. The database was designed and is being populated with data.

The objective of this project is to develop reliable and generally applicable d esign and test methods for electrochemical reactors of various natures and indu strial relevance. The obtained results will yield essential design tools (CIME- tools) and methods to many branches of the electrochemical industry: plating i ndustry (contacts, PCB's, Semiconductor IC manufacture, Smart cards, spot plati ng, strip and wire plating, ...) where it is a major problem to obtain uniforml y deposited layers on well defined places, etching industry (for micro-mechanic al parts in valves, watches, offset printing plates, ... ), anodising industry (for complex shapes in aviation and aeronautics, for high quality offset printi ng), electrochemically made micro-systems and the electrochemical waste recover y industry. In all of these electrochemical systems, mass transport phenomena o f charged species (due to diffusion, convection and migration by electrical for ces) are strongly coupled with the electrochemical reaction(s) at the electrode s. Also temperature effects, gas formation and evolution are to be considered. Based on fundamental research results obtained so far within the scope of the B rite-EuRam II and the Brite-EuRam III programmes, a new partnership with mainly industrial partners is essential in order to achieve the following objectives: - Step by step elaboration of available numerical methods for modelling of el ectrochemical systems with complex electrode processes in order to reach a desi gn code at industrial level. - Adaptation to and integration of these numerica l tools with commercially available software (CAD, flow solvers, visualisation) . - Quantification of several electrochemical systems resulting into reliable model parameters. - Application of this new design environment to highly deman ding industrial electrochemical cells in diverse fields: copper, chromium and g old plating, micromachining and fabrication of micro-magnetic components. - Co nstruction of various electrochemical industrial test reactors for these proces ses. - Experimental verification of flow, mass transport, current density, thi ckness, temperature and potential distributions in these reactors. - Compariso n of measured and designed objectives with evaluation of the limits of applicab ility of reactor design tools (including correlation of local properties of a d eposit (hardness, wear resistance, ...) to local quantities such as partial cur rents, potential and concentrations of interfering ions). As most fundamental a nd theoretical aspects are already available, the proposed project is considere d as pre-competitive Industrial Research. The partnership structure contains tw o major manufacturing industries, one software company, one university and two research centres. The university elaborates the developed numerical methods to solve the electrochemical models and will perform research on the electrode rea ction kinetics. One research centre provides the numerical knowledge on automat ed grid generation and time integration. The software company is a young starte r that will bring the new scientific software to a pre-competitive level needed to perform the designs. The two major manufacturers and the second research ce ntre will apply the design tools, build several industrially relevant reactors in order to evaluate the methodology by measuring their performance. In this wa y an evaluation of several design options becomes possible, hence providing the data needed for general application of integrated and optimal design combining know-how with numerical and statistical tools.
