Abstract:

Reducing electromagnetic interference over a broad band of radio frequencies is crucial to eliminate the adverse effects of the increasingly complex electromagnetic environment. Current shielding materials or methods suffer from tradeoffs between optical transmittance and EMI shielding capability. Moreover, poor mechanical flexibility and manufacturing complexity significantly limit their additional applications in flexible electronic devices. In this project a technology will be developed to manufacture transparent conductive thin layer structures with thicknesses of max. 600 nm, with a surface resistance of max. 100 ohms / square for a shielding efficiency of at least 25 dB and for anti-static effect with a surface resistance of maximum 1000 ohms / square, on flexible and rigid transverse substrates for transmissions in visible of at least 80%. Transparent EMI shielding components will be made and tested. The thin layers of electromagnetic protection will be made in the form of a suitable design (eg conductive-dielectric-metal-dielectric) to improve the electro-optical compromises, to obtain a transmittance in the visible spectrum of at least 80% in relation to the substrate and an excellent efficiency. of shielding effect (SE-shielding effectivnes)> 25 dB, over a broadband bandwidth of up to 30 GHz, covering all bands X, Ku, Ka and K. An efficiency of EMI shielding> 30 dB is estimated to be achieved by the overlap of at least two transparent conductive thin layers and could be further improved up to 50 dB by separating two layers with a quarter-wavelength space. High-performance flexible or rigid substrate thin-layer structures have high potential for various applications such as: portable electronics, medical devices and electronic safety zones.

Abstract:

Proiectul propune designul conceptual (TRL2), dezvoltarea (TRL3) si validarea la scala de laborator (TRL4) a unui model demonstrator de mediu de filtrare textil cu straturi micro sau nanometrice realizate prin electrofilare, pentru separarea particulelor in suspensie din solutii apoase. Proiectul FILTER furnizeaza medii de filtrare multistrat imbunatatite, ce includ o structura textila mono sau multistrat, un strat subtire din fibre polimerice electrofilate si un invelis protector dintr-un strat continuu de fibre. Structura cu 3 straturi a mediilor de tesaturi filtrante avute in vedere vor fi caracterizate prin eficienta ridicata de captare a particulelor si o restrictie minima a curgerii. Proiectul furnizeaza un nou concept pentru mediile de filtrare pe baza de tesaturi foarte subtiri ce permit utilizarea mai multor straturi functionale/unitatea de volum si au o eficienta imbunatatita. Principalele obiective: (i)design conceptual si demonstrarea funcționalității conceptului pentru modelul demonstrativ de mediu de filtrare textil cu straturi polimerice electrofilate/strat de acoperire si structuri textile inovative cu dublu rol (ranforsare si filtrare); (ii) dezvoltarea si validarea in laborator a modelului demonstrator de medii de filtre tesutura cu straturi polimerice electrofilate. Latura inovativa a cercetarilor ICPE-CA consta in sinteza/caracterizarea de micro(nano) fibre electrofilate, selectate in functie de utilizarea materialului in filtrarea solutiilor apoase. Latura inovativa a cercetarilor INCDTP se reflecta in dezvoltarea structurii textile mono si multistrat cu componenta cu dublu rol pentru filtrul flexibil compozit: structura textila este realizata astfel incat sa asigure o comportare uniforma a filtrului compozit flexibil in timpul utilizarii si mentinerea unui strat superficial suport al micro si nanofibrelor; compozitia structurii textile va fi completata cu un strat de fibre electrofilate astfel incat sa asigure functii optime de filtrare.

Abstract:

The large concern of global energy challenges has greatly increased the interest and investments in renewable and clean energy that can replace fossil fuel. Among all known systems to generate energy, solar power is the most promising one. Hence, no one doubts the important role that photovoltaics (PV) are going to play in the energy of the future. The main drawbacks of the current PV technologies are their high production cost and rigid structure in the case of traditional silicon and inorganic semiconductors, or their reduced efficiency and durability in the case of organic and DSSC photovoltaics. One of the bottlenecks of increasing the conversion efficiency in DSSC is the transport of photogenerated electrons. The general approach to surpass these limitations is employing one of the following strategies: doping, growing vertically oriented porous structures on top of the conducting substrate, interconnecting TiO2 nanoparticles with charge carriers to direct the photogenerated current or find alternative materials with higher electronic mobility. Due to the richness of its optical and electronic properties, 3D graphene is the material of choice for our proposed studies. The ability to develop free-standing 3D graphene structures with large specific surface area will enable the successful realization of fast transport channels of charge carriers, thus leading to high electrical conductivity. Moreover, by combining their good electrical conductivity with their porous structure, the 3D graphene structures will increase the photocurrent density of DSSC by enhancing light absorption (sensitizer loading), enabling efficient charge separation and light scattering. In this context, the general objective of the project is: to evaluate the functionality of the 3D graphene structures in optoelectronic devices, specifically in photovoltaic cells (DSSC).
