2 Convergenta stiintelor si a tehnologiilor in PC7 Convergenta stiintelor? De fapt o cercetare multidisciplinara. Exista de multa vreme biofizica, biochimie, chimie fizica etc.Convergenta tehnologiilor: apar atunci cand anumite tehnologii patrund intr-un nou domeniu de aplicatii, de fapt un domeniu care isi are deja tehnologiile proprii.Convergenta tehnologiilor in PC7.Micro-nano-bio-info sau micro-nano-bio-cogno. Suprapuneri intre tema ICT (TIC) si NMP, dar si cu tema Health (Sanatate). Aceasta arata interesul exceptional pentru anumite subdomenii.

4 New!Micro-OptoRF (Microwave, Millimeter Wave)Opto (Photonics)Two laboratories from IMT (former centres of excellence in RELANSIN and MATNANTECH, respectively)Now designed as a common structure: a Centre of excellence of EU in RF and Opto MEMS (MIMOMEMS).
5 A new project was invited for negotiation in Brussels MIMOMEMSA new project was invited for negotiation in BrusselsEuropean Centre of Excellence in Microwave, Millimetre Wave and Optical Devices, based on Micro-Electro-Mechanical Systems for Advanced Communication Systems and Sensors – MIMOMEMS►Capacities - Part 4 - Research Potential.Activity: 4.1.Unlocking and developing the research potential in the EU´s convergence regions and outermost regions (REGPOT )►Cooperation – Theme 3 - Information & Communication Technologies.Challenge 3: Components, systems, engineering● The overall aim of the MIMOMEMS project is to bring the research activity in RF and Optical-MEMS at the National Institute for R&D in Microtechnologies (IMT) to the highest European level and create a European Centre of Excellence in Microwave, Millimeter Wave and Optical Devices, based on Micro-Electro-Mechanical Systems (MEMS) for Advanced Communication Systems and Sensors.● The Centre of Excellence will be created by developing IMT- Bucharest’s existing scientific expertise and capacities and collaborating closely with specialist research groups at LAAS-CNRS in Toulouse and FORTH-IESL-MRG in Heraklion.

8 O perspectiva mai larga Convergenta tehnologiilorNu este ceva nou (v. exemple mai departe)Ridica dificultati suplimentarePoate duce la convergenta industriilor (v. exemple mai departe)Un cocktail exploziv: micro-nano-bioIn general – noile materiale si tehnologii pot afecta industriile traditionale
9 Convergenta in “tehnologia electronica” Ultimul deceniu al secolului trecut: convergenta intre industria comunicatiilor si industria calculatoarelor (de fapt tehnica calculatoarelor digitale (cifrice, numerice) a patruns in tehnica comunicatiilor (initial analogica).Astazi avem TIC = tehnologia informatiei si a comunicatiilor (si industria TIC), dar are loc un alt fenomen: convergenta TIC cu “industria media”.Un contraexemplu: TIC se aplica si in constructia automobilului (gasim produse TIC in automobil, pe liniile de fabricatie), dar aceasta nu inseamna convergenta tehnologiilor.
10 Care sunt implicatiile? Potentialul este enorm, dar apar si o serie de dificultatiNecesitatea unei formatii interdisciplinare a specialistilor (de ex. pentru proiectarea unui microsistem electro-mecanic, MEMS).Abordari diferite (paradigme diferite) care ingreuneaza mult colaborarea. Colective “mixte” de cercetare – esentiale pentru formare.Sunt interesate firme de diverse “calibre”, dar ele nu au toate mijloacele necesare (expertiza, dotari) pentru a aborda produse noi cu tehnologii avansate, neconventionale (v. platforma MINAM).Micro-nanofabricatie: accesul firmelor! ... Cel mai practic “One-stop shop”?
11 A new concept for a new era! An “open” lab is containing various (up-to date) equipments. An equipment may incorporate a immense amount of new knowledge; at the same time it may be seen as a platform for creating, disseminating and using this knowledge (most of it as “know-how”)Open to researchers from other labsOpen to researchers from other organizationsLaboratory open for companiesLoboratory open for educationThe so-called “knowledge triangle”: research, education, innovation

22 New Equipments in the NANOSCALE- LAB ► SPM - Multifunctional Scanning Probe Microscope NTEGRA Aura (NT-MDT) has been recently installedIt allows operation in air, liquids, low vacuum (10-2 torr) and controlled gaseous atmosphere.Vacuum operation optimises the resonance frequency or "Q factor" of the cantilever, producing better images for semi-contact AFM modes and increased sensitivity for non-contact modes such as MFM (magnetic force microscopy) and EFM (electrostatic force microscopy).Temperature control of the sample is possible up to 200°C. The special Thermohead™ provides extremely low thermal drift , which allows long-term measurements to be done in pre-defined points on the specimen surface.
