Fabrication and characterization of bilayered tissue scaffolds incorporating bioactive agents for skin tissue engineering applications
Aktürk, Ömer; Keskin, Dilek; Bilici, Temel; Department of Engineering Sciences (2015)
In this study, it was aimed to fabricate tissue scaffolds from different biological polymers (collagen, silk fibroin and sericin) for skin tissue engineering applications. For this purpose, bilayered scaffolds composed of epidermal (collagen/sericin films) and dermal (collagen sponges, collagen matrices or silk fibroin matrices) layers were produced with different biomaterial fabrication methods. Casting and solvent evaporation (film), lyophilization/freeze-drying (sponge) and dry/wet electro-spinning (micr...

Poly (ether ether ketone) (PEEK) has attracted the interest of bone tissue engineers due to its close range of mechanical properties to that of human bones, its biocompatibility, and excellent chemical resistance. However, PEEK is bioinert and has very low hydrophilicity. Sulfonation can compensate for this by introducing hydrophilic sulfonate groups. Furthermore, hydroxyapatite (HA) which is the main component of the bone, can introduce bioactivity to the scaffold. Compared to pure HA, Fluoridated hydroxya...

This paper presents the fabrication of wafer-level hermetic encapsulation for MEMS devices using low-temperature (300 degrees C) Au-Sn bonding together with their pre- and post-bonding characterization. Thermal evaporation method was used for metallization which is easy and controllable method for low thickness metallization. In this respect, the current study represents preliminary characterization results of Au-Sn pre-and post-bonding with an average thickness of less than 1.5 mu m processed by thermal ev...

In this study, copper oxide (CuO) thin film/silicon (Si) nanowire heterojunctions have been fabricated and their optoelectronic performances have been investigated. Vertically aligned n-type Si nanowires have been fabricated using metal-assisted etching (MAE) technique. CuO thin films were synthesized by the sol-gel method and deposited onto the nanowires through spin-coating. Fabricated nanowire heterojunction devices exhibited excellent diode behaviour compared to the planar heterojunction control device....
Fabrication and characterization of porous tricalcium phosphate ceramics
Koc, N; Timucin, M; Korkusuz, Feza (Elsevier BV, 2004-01-01)
Preforms of beta tricalcium phosphate (beta-TCP) ceramics were produced by using a modified slip casting technique. The slip was prepared by suspending custom-made TCP powder and PMMA beads in an aqueous medium stabilized with an acrylic deflocculant. Porous TCP ceramics were obtained by sintering the polymer-free preforms for 2 h at 1000 degreesC. The XRD pattern for the TCP ceramic indicated that the product was essentially pure beta-TCP. SEM examination of pore size and pore size distribution revealed th...
