Light confinement strategies in thin film silicon solar cells play a crucial role in the performance of the devices. In this work, the possible use of Ag coated stamped polymers as reflectors to be used in n-i-p solar cells is studied. Different random roughnesses (nanometer and micrometer size) have been transferred on poly(methylmethacrylate) (PMMA) by hot embossing. Morphological and optical...

we report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, ii in these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

The electromagnetic interference shielding properties and the electrical of poly (methylmethacrylate) (PMMA) based composite materials prepared using different types fillers (multi-wall carbon nanotubes, black, silver coated glass microfibers) have been investigated in a broad frequency range. By combining theoretical an experimental analysis we show that, irrespective nature conductive materia...

In this study, poly(allylphenol-co-methylmethacrylate-co-vinyl imidazole) (PAMV) terpolymer adsorbents were synthesized using the photopolymerization method with 1-vinyl imidazole, methyl methacrylate, and 2-allylphenol monomers. Structural surface analyzes of PAMV polymers obtained different mole ratios 1H-Nuclear Magnetic Resonance, Fourier-Transform Infrared Spectroscopy, X-Ray Photoelectron...
